Research On The Quality Management Of The Zhuyan Bridge Reconstruction Project Of Yanshang National Highway

Highway Bridge is an important infrastructure of the country, which is to ensure the smooth flow of all kinds of materials in the throat. Once the Highway Bridge is damaged, it is difficult to be repaired, which is need to spend a lot of manpower, material resources, financial resources, and which will cause a long traffic inconvenience.With the rapid development of our economy, because of the insufficiency of the early construction of the bridge standard and low bearing capacity, and thus hinder the smooth flow of traffic, road traffic "bottleneck". Especially large, heavy vehicles grow with each passing day, the highway traffic safety and smoothness is seriously affected, therefore strengthening, reconstruction, widening the existing bridge for improving capacity and service level, in order to ease the growing tension traffic pressure, so that the bridge construction sustainable development becomes more and more important and prominent. Increasing the bridge reconstruction project, the bridge construction project quality has an important influence on the whole network. Under the influence of the objective factors, there is a Greatly problem. Those factors is include the construction personnel improper operation and the construction method is not scientific, and so on. Those problem is not only led to the emergence of many quality problems in bridge construction, shortening the service life of the bridge, but also bring hidden dangers to the vehicle and pedestrian safety.Zhuyan bridge which was evaluated by the testing agency is the four types of bridge and it need to be reconstructed. Pearl rock bridge reconstruction project tender notice issued in August 16,2013. On September 10, signed construction contract. Construction started in September 12,2013.2013 11 at the end of the opening plan. Quality management as an important part of project management, the bridge safety, responsibility be weightier than Mount Tai, concerning the road traffic safety, is related to the safety of people’s life and property, which is the image of the industry and the credibility of the government. In this paper, through the National Tobacco on-line pearl rock bridge reconstruction project as the research object, by using of the method of the total quality management and building all kinds of systems. and using the method of 4M1E. Further research and analysis of the factors affecting quality management and safeguard measures. research and analysis of the influence factors in quality management, and various methods and control measures, Especially the histogram method is used to control bridge reconstruction in cement concrete strength, And the method of three phase control which has achieved remarkable results and will help to control the quality of bridge.
