Study On Construction Quality Management Of Twin-block Ballastless Track In Hu-kun Passenger Dedicated Lines

High-speed rail is a special construction engineering products, the characteristics of the high-speed rail reveal that the quality of high-speed rail is very important. CRTS I type twin-block ballastless track is a kind of embedded type and has characters of low track structure, low construction difficulty, low engineering cost and good performance of engineering structure. Those advantages make it being the relatively advanced and safe high-speed rail construction mainstream form orbit, which has been used widely.In order to guarantee high quality of the Shanghai-Kunming Gao Tie Chang Kun segment part Ⅱ project which is undertaken by East China road &bridge engineering co., LTD., and guarantee the twin-block ballastless track can meet the design requirements, and guarantee the safety of Shanghai-Kunming Gao Tie which may bring huge economic value and social benefits, we must strengthen the construction quality management. This thesis has summarized the engineering quality management theory at home and abroad, and has analyzed the drawbacks of Shanghai-Kunming Gao Tie Chang-Kun segment part II project. Basing on that, we combine the thesis and drawbacks with the character and target of quality of this project and refer to the management method of the project, then construct a quality management system which may suitable to this project. The main aspect of the quality management system includes:By cultivating the comprehensive quality management consciousness, we intend to optimizing the quality management organization of high-speed railway construction project. We establish a quality management mechanism which include all employee. We establish scientific construction procedures which may help us guarantee the quality of the project. We try to obtain harmonious resource configuration position among manpower resource, production equipment, raw materials and construction environment by optimizing the configuration of factors of production. We try to establish comprehensive quality monitoring and measuring system of the project. Eventually, we establish a quality inspection group to inspect the effects of quality management system and found that this system can improve the quality of the project.Eventually, we try to guarantee a high-quality high-speed CRTS I type twin-block ballastless -track and hoping that this research can provide a good theoretical guidance to other high-speed project.
