Concrete Poles sustained and healthy development of the industry to
Electricity is the lifeblood of the national economy, is one of the important basic industries. Since the reform and opening up, increasing investment in power construction, the annual investment to more than an average of 8 percent growth rate, which led to the rapid development of the concrete pole industry, but also the resulting serious excess capacity, causing competing industry. "Twelve Five" period, the government on strengthening the quality of products, upgrade and major policies of the integrity of the building has been introduced, with the State Council to accelerate the pace of reducing political decentralization, administrative intervention, trade protection and market access barriers will also be with the market economic role continued to strengthen gradually weaken, while bidding gradually scientific and standardized. In this situation, product quality, market integrity will become the cornerstone of the survival and development of fundamental, evergreen industry.
First, companies should re-quality, integrity
Quality is the power grid and the majority of manufacturing enterprises lifeline, is the survival of the Founding of the base business. Strengthening quality management, enhance the competitiveness of industries and products, it has become an important trend and direction of development of modern business management.
1. The Government attaches great importance to the quality of work
Party "Eighteen big" proposed to achieve "two hundred years," the strategic objectives, requirements to promote economic development standpoint to improve quality and efficiency. State Department "Quality Development Outline (2011-2020)" proposed "quality development and rejuvenation of the road, the power policy, adhere to quality, construction quality power, is to enhance the comprehensive national strength and realize the great rejuvenation of the Chinese nation; to fully improve the quality of management, promote the construction of power quality, and promote sound and rapid economic development. " Recently, the State Administration of Quality Supervision, the National Development and Reform Commission, Ministry of Industry jointly issued the "on the strengthening of important equipment supervision work," which clearly contractors or suppliers of critical equipment or contractor responsible for the design of major equipment orders, manufacturing, installation quality , called for the effective implementation of the quality and safety of vital equipment responsibility to ensure the quality and safety critical equipment and investment efficiency, promote the upgrading of manufacturing quality. Grid Corporation of all levels has always adhere to the "quality first, price is reasonable, good faith win-win" concept of procurement, held a "re-quality, integrity," the initiative will promote.

2. The power grid construction equipment and materials for new requirements
Currently, new energy technologies, distributed generation technology, large-scale energy storage technology, ultra-long distance transmission of large-scale technology, information network technology and the rapid development of intelligent control technology, the world has entered the grid smart grid development stage. Future smart grid grid is strong and extensive network, highly intelligent, open and interactive "energy internet." Smart grid will promote energy development approach, configuration, consumption, production and lifestyle changes, and promote the development of strategic emerging industries, is carrying the basic platform of the third industrial revolution. We need to accelerate the development of smart grid construction of UHV power grid, with the construction of power grids to accelerate, accelerate the upgrade of interactive grid capacity. With the development of smart grid construction, we need a large number of new materials, new technologies, new processes, product quality and made more stringent requirements; With the growing market demand for grid materials for manufacturing enterprises supply schedule, and a higher quality of service requirements. To implement concrete pole industry, it is to give full consideration to improve the durability and green development, give full consideration to the distribution network complexity and diversity. China has a vast geographical and meteorological conditions differ greatly from industry to improve the applicability of concrete pole pole, developed a lightweight, high strength, for a variety of corrosive media and meteorological rod-geological conditions; to continue implementation of technological innovation and strengthen management, improve the quality and effectiveness of products; to establish a service concept, the implementation of service measures, honest and trustworthy, to improve the integrity of the industry.
3. The special nature of the grid determines the quality management needs unremittingly
As the relationship between China's energy security and national economy of the grid, a matter of social stability and economic development. Various types of grid failure may cause life and property of the state and the people suffered huge losses and serious social impact.
For example, in 2003 Canada '8.14' blackout, power range of 2.4 million square kilometers, up to 29 hours, the loss of load of 61.8 million kilowatts, an economic loss of $ 30 billion; 2005 Moscow "May 25 blackout" caused at least $ 1 billion in economic losses, 20,000 passengers were trapped underground; 2011 Korea "September 15" blackout caused traffic gridlock, commercial chaos. Strengthen the country's current industry safety regulation and accident investigation process, in 2012 the State Council issued the "electrical safety and accident investigation and handling of emergency regulations," the establishment of a safety accident accountability mechanisms electricity. In the construction and operation of the power grid, the grid company always put the security and stability of high-quality and reliable power supply and on the first one, the quality of the work in a prominent position. Concrete pole as a supporting structure of transmission and distribution lines, it is the grid security pillar. Therefore, the only industry colleagues to stresses integrity, quality, and firmly establish the awareness of quality-oriented, comprehensive quality guard against all kinds of risks and hazards, to ensure product quality to ensure safe and reliable power supply strong power grid.
4. To re-quality, integrity is the fundamental business survival and development, is the need to participate in market competition
Power Grid Corporation to carry out the qualification of suppliers capability verification, focusing on the competent supplier quality system, technology, production equipment and other nine aspects of document and on-site verification, played down the registered capital and performance, established supplier information files, to meet the requirements of suppliers to issue a "multi-paper proof" to strengthen the supplier performance evaluation and tendering linkage to develop a performance evaluation scoring rules, according to "who use, who evaluate" principle, the establishment and improvement of supplier performance evaluation information base, organizational units of the project after the successful vendor compliance (including product quality and after-sales service, etc.) regularly evaluate, quantify scoring, and evaluation results of the tender for the work of the supplier's.
Power companies continue to strengthen supervision and sampling work. State Grid Corporation of the Year 2013, sampling a total cement pole 9665, involving 206 suppliers; the first half of 2014, sampling a total of 4314, involving 141 suppliers. Spot checks found that the main problems include:
(1) The main appearance of inferior quality, including surface cracks, plasma leakage, bumps, broken ends, exposed tendons, sealing off the head, pockmarked face sticky skin;
(2) the size of allowable deviation unqualified, including rod length, wall thickness, the thickness of the protective layer, rod diameter, curvature, and some indicators of substandard quality steel skeleton and the like;
(3) Mechanical and chemical composition of steel, concrete strength, mechanical properties pole failure;
(4) in the presence of reinforcement welding defects.
In this regard, power companies regularly exchange director making, sampling, installation, commissioning and product quality problems found in the operational phase, the establishment of information base, and increase efforts to deal with quality issues. In follow-up in the bidding evaluation points, to suspend the tender for serious blacklisted before the completion of the rectification shall award. 2013 State Grid Corporation common occurrence product quality, integrity and non-compliance issues such as suppliers, dealt with a total of 77 105, the provincial network company handles a total of 628 suppliers 883 times. Which, due to product quality issues deal with suppliers relatively high, reaching 618 times, accounting for 63%; supplier compliance rate of 232 times a problem, 23%; Honesty 138 times, accounting for 14%. Power Grid Corporation launched gradually suppliers classified administration to carry out supplier credit rating, credit history build products, and linkage with the bidding.
Although there are some irrational evaluation methods in the current bidding activity, it may be some good quality and good reputation and outstanding enterprises suffer a temporary phenomenon exists, power companies also failed to some of the larger scale, strong technical force, product quality and stability reliable, high integrity of enterprises to develop a favorable scientific evaluation methods, to give some protection; but we should also see that the grid company has taken strong measures to carry out the tasks referred to above and continue to actively explore and improve, guarantee entire bidding science, open, fair and impartial manner.
We firmly believe that with the grid companies gradually improve materials management, systems, measures increasingly comprehensive, scientific evaluation methods gradually standardized, quality priority will be to build a competitive platform supporting the superior and inferior punishment, a large number of high quality, stresses integrity outstanding enterprises will certainly emerge, grow and develop.
5. Concrete Poles quality is still much room for improvement
After several years of quality supervision authorities and users at all levels continue to increase quality control and treatment efforts, as well as the tireless efforts of all my colleagues in the industry, the quality of the concrete pole made great progress, quality sampling pass rate of over 90%. But the quality of the accident still occur, the product quality from the standard requirements are still gaps, such as: reinforcement spacing deviation, pitch deviation erect circle, spiral reinforcement spacing deviation exceeded; pole geometry exceeded; the thickness of the protective layer does not meet the requirements; 28 days and stripping strength of concrete is low; the appearance of the main substandard quality, including surface cracks, plasma leakage, bumps, exposed tendons, heads off, sticky skin pockmarked face, end breakage; pole mechanical properties; steel butt weld defects test failed. The root of these problems, there is not strong sense of quality, failure to strictly enforce product standards, lack of technical personnel, business quality assurance system is not perfect or may not be implemented, the raw materials into the plant strict, strict process control, production conditions simple, tooling equipment behind the lack of test equipment inspection instruments. At the same time due to the overall overcapacity, fierce competition in the market, some companies at the expense of product quality and to reduce costs, the use of inferior materials, the system does not execute processes, reduce design safety factor, and even act as a high-grade low-grade pole pole, etc., which are the actual problem is the quality of work and the need to improve the presence of the current.
Second, actively create a "re-quality, integrity" business
And ensure and improve product quality, in the final analysis have to rely on their own.
1. Establish quality to win the core concept and the correct concept of efficiency
Enterprise is the product manufacturer, is the main guarantee of product quality, product quality bears a fundamental responsibility. To win in the competition to win more market share, we must adhere to quality as the fundamental enterprise development. Power companies will create a fair competition, survival of the fittest in the market environment, and will be excellent quality, honest and trustworthy, reasonably priced enterprises to establish strategic cooperative partnership, and jointly safeguard the quality of the first values.
As the saying goes: a gentleman's love of money, in a proper way. Industry colleagues should establish a correct concept of efficiency, ensure the quality of the premise, to create greater efficiency. To optimize the design work hard, work hard in the transformation process, efforts in the management of the energy saving efforts, rather than opportunistic, shoddy, shoddy to obtain benefits. No quality, companies will no dignity.
2. Implementation of specific measures of quality assurance
Industry colleagues should abide by the commitment to quality when bidding, strict implementation of the measures of the corporate quality assurance system. Strengthen the selection of raw materials, process control, factory testing to ensure that products manufactured zero defect; strengthen poles during transport management, technical and management measures to prevent damage are not in place; enhance on-site technical guidance to ensure the quality of the installation; do service strengthen the operation of the network products monitoring and analysis, continuous improvement and improve product quality. Re-quality, integrity can not just empty slogans, must implement specific measures.
(1) To design is reasonable, rational use of high strength materials, after experimental verification before market. The current three, four rebar used more often, from the theoretical calculation, it is easy to meet the requirements of flexural strength, deflection but can not meet the requirements. Many big moment pole, configured with a number of non-prestressed reinforcement, bending strength is rapidly increasing, but the degree of cracking does not meet the standard requirements; many ordinary reinforced concrete poles cramps or unreasonable in order to save material, resulting in substandard pole deflection . Therefore, to conduct a comprehensive design calculations, including normal section bearing capacity, Shear Resistance, rupture strength and fracture width, deformation calculation, the new rod-type test to be carried out to ensure that the mechanical properties of all meet the national standard " annular rib concrete pole "(GB / T 4623-2006), can be put into mass production. Many companies do not test chamber, concrete mix generous, never adjust; not with the actual situation of their own raw materials, applied on books or other business mix, resulting in unnecessary waste or concrete strength less than the design requirements.
(2) To strengthen technological innovation, preferred the new equipment, new technology to ensure product quality, improve labor efficiency, reduce labor intensity and improve the working environment. Such as the use of automatic batching system with a concrete mixing station mixing or mixing building, while providing the necessary measurement basis for the introduction of admixtures and admixture; steel frames are made; the use of concrete pumping technology feeding, metering charging can improve work efficiency roller welder skeleton made entirely satisfy the "ring of reinforced concrete pole" (GB / T 4623-2006) demands, while downsizing to improve efficiency, reduce costs, improve shop dust pollution of the environment; the implementation of conservation or conservation kiln pit, to be supporting automatic control systems for steam, steam curing system controllable process parameters, both to ensure quality and save energy; automatic lifting clamps, can improve work efficiency, reduce the occurrence of accidents.
(3) capacity building to strengthen the quality inspection, sound laboratory. From raw materials into the plant re-examination, to finished product factory testing to detect the full control. Shall be equipped with gravel, cement, concrete specimens with concrete strength, curing room, the mechanical properties of the steel, mechanical properties seized pole test equipment, equipped with trained forensics testing personnel to ensure that data used to speak, rather than empirical judgment qualified or not.
(4) To carry out technical R & D innovation, improve product quality, and promote the transformation and upgrading. The past two years, most of the production conditions and production technology has been improved and enhanced. High-strength steel, high-performance concrete, concrete and even powdered active pole start applying to production; all kinds of additives, admixture, artificial sand there are some enterprises began to apply; prestressed steel tension, ordinary steel straight dual control technology; applicable to a specific natural conditions of special poles also successfully developed, such as sulphate resisting poles, chlorine resistant poles, freeze-thaw resistance poles, light poles and other; for a variety of specific areas pole also on the market, such as wind power pillars, mobile communication base stations, oilfield special rods, bars and other high-speed rail; carried out on durability of concrete poles, such as follow-up study on alkali aggregate reaction, fracture effect mechanism, anti-corrosion and so on; part enterprises over secondary use of slurry, gravel washing water recycling, reduce production costs, implements energy conservation, green development. The next two years will be a key moment to upgrade technology industry, the overall level of technology and equipment will be a fundamental change, to accelerate the joint development and research institutes, universities, equipment manufacturers, to promote the industry to accelerate the mechanization and automation, digital, information technology and other technological advances.
(5) to strengthen management, improve quality and efficiency. Improve management is a deep understanding of long-term behavior, not a whim or a short-term behavior. To concentrate, can not rely on small smart, do not blindly deliberately bigger and stronger, we must make solid. Quality and efficiency to the long-term management, to develop labor quota and material consumption norms, implementation of performance appraisal; clear quality standards, standardized process discipline, increase enforcement. For some quality details to attach great importance to efforts to solve, and must not turn a blind eye. To do equipment maintenance and repair, never sick operation, in particular centrifuges and steel, but also often maintenance. Boilers, pressure vessels, cranes to inspection, and the operator should certificates. Regarding safety, quality measurement equipment according to test cycle timely check. Pole industry also belong to high-risk industries, training and management should pay attention to safety, to prevent the occurrence of major accidents.
(6) to strengthen the training and exchange of learning. Publicizing the relevant standards should be organized, and timely investigation new; the quality assurance system, technical rules, operating procedures, product quality inspection standards, to adhere to long-term training, so well-known applications. Such as "Concrete Structures for Construction Quality Acceptance" (GB50204-2011) provides: rebar into the factory inspection, the first for weight deviation test, then take two specimens mechanical properties testing; Yield strength reinforcement ratio of not less than 1.25 super flexor ratio should not exceed 1.3 bars maximum force, the total elongation of not less than 9%; mechanical properties and should be tested after weight deviation of reinforcing bars straight, strength, elongation after fracture, weight deviation should meet the standards provisions. It provides bar straightening process control requirements. Steel straightening machine straightening method should be used, there should be no extension of their equipment function; when cold straightening pull method, cold-drawn round bar rate should not be more than 4%, ribbed cold-drawn steel rate of not more than 1%. Has promulgated the "ring of reinforced concrete pole" (GB / T 4623-2006), clearly expressed by cube specimens to evaluate the concrete strength, but some companies still using centrifugal concrete strength, which uses cube strength multiplier centrifuged increase coefficient to assess the strength of concrete.
Peer learning should strengthen exchanges, learn from each other, which is the minimum investment, detours, effective way to improve the fastest. Some outstanding enterprises not close our doors to go abroad for international academic exchanges, so as to enhance the industry's quality and technical level, and enhance the industry's competitiveness and vitality.
3. actively build corporate integrity
Credibility is one of the manifestations of morality is to ensure the quality of the bottom line, and so is the business management and technical factors into full play the role of a cornerstone. If you lack credibility, advanced management and technology will not be able to uphold and comply with, the product quality can not be guaranteed. Can not effectively guarantee product quality companies will inevitably lose the trust of users, lose the trust of society, and ultimately be eliminated.
Enterprises should actively participate in the first to excellence activities, the implementation of quality and integrity as the core content of the brand development strategy; to carry out quality management system certification, product quality certification, measurement certification, environmental and occupational health and safety certification, laboratory accreditation, etc; carry out credit management, performance management Excellence model Standards Implementation activities; strengthen ideological and cultural construction, the development of corporate vision, mission, core values, business development planning in the future. Through a series of effective work and activities to promote the quality, honest work in depth, and actively create the quality of corporate integrity.
Industry colleagues should maintain a strong sense of crisis and urgency, a sense of honor, to establish a correct concept of quality, competition, values, inspire a strong sense of responsibility, initiative, professionalism. Treat the quality and integrity of the work can not have the slightest slack, treatment quality and integrity issues can not have the slightest negligence.
"Twelve Five" period, the State Grid Corporation of an annual investment of about 300 billion yuan, of which 200 billion yuan for the purchase of equipment and materials; 2020, to build "five vertical and five horizontal" backbone UHV power grid, most cities formed 220 kilovolt (kV or 110) bicyclic grid, 500 kV (or 330 kV) substation in-depth urban load centers and the formation of 500 kilovolt (kV or 330) ring structure, to achieve 500/220 kV (or 330 / 110 kV) between electromagnetic loop operation, low voltage distribution network with the "Hand in Hand" loop-powered or dual power supply; the initial formation of 220 kV voltage level as the central hub, 110 kilovolt (one thousand 66/35 V) grid voltage level based strong distribution network in rural areas, county medium voltage distribution network to achieve ring network power supply, power supply capacity of the overall level of technical equipment and reliability has been further improved to meet the economic and social development in rural areas and the new rural construction demand for electricity; the promotion of large-scale, oil-free, insulated, low (Free) maintenance, energy-efficient, intelligent devices. Faced with good opportunities for development, industries and enterprises still have hard skills, strengthen themselves, dare to play, honest and trustworthy, to provide quality products and excellent service for the power construction and transformation, and jointly promote the healthy and sustainable concrete pole development.
