Research On The Quality Control Of Civil Construction Of Harbin Metro Line 2 Project

Metro is an important transportation system in a city.It can effectively solve the traffic congestion problem,improve the efficiency of residents' travel,save land,protect the environment,and stimulate the surrounding economy.Therefore,in recent years,it has become the mainstream of infrastructure construction in China's first and second-tier cities.It can be said that the current metro construction has entered a peak period.Usually the service life of Metro is 100 years,so the construction quality of metro construction is an important prerequisite to determine whether the expected use goal can be achieved,and the quality of civil construction is the most important.According to the prese nt situation of quality control of International Metro construction projects.According to the current situation of quality control of International Metro Construction projects,this paper summarizes the relevant international research literature and draws on the research experience of related project construction.In view of the actual situation of the civil engineering project of Harbin Metro Line 2,the research contents,research methods and technical routes are formulated.According to the current situation of quality control of International Metro Construction projects,this paper summarizes the relevant international research literature and draws on the research experience of related project construction.In view of the actual situation of the civil engineering project of Harbin Metro Line 2,the research contents,research methods,technical routes and quality control measures are formulated.Guarantee measures should be taken to manage the key parts and construction links of the project in an all-round way,to promote the quality of the project to become excellent at one time.Because of the long winter,cold and other unfavorable factors,the construction of Harbin Metro is at the initial stage,and only one metro line is in operation.This paper takes the quality control of civil construction of Harbin Metro Line 2 as the research object,and studies the quality control in three stages of pre-construction,mid-construction and post-construction.The purpose is to explore the quality control methods of Metro Construction in alpine areas,accumulate experience,improve the construction quality of Harbin Metro Line 2 and provide reference for similar projects in the follow-up.Firstly,this paper makes a comprehensive investigation and analysis of the project(including the general situation of construction and construction proce ss),decomposes the project,analyses the internal and external environmental impact factors,and plans out various key difficulties that may be encountered in the process of project construction.It lays a foundation for the formulation of the construction quality plan of the project,and provides a basis for the quality assurance and control measures of the project.On this basis,the construction quality management plan is worked out.Plan for project quality policy,goal and excellence creation,and formulate various quality control measures.In the process of construction,it should be controlled and implemented.Finally,according to various control measures,from the aspects of organization,system,margin,assessment,construction scheme and so on,the construction quality assurance measures are put forward.Ensure that the construction site is strictly in accordance with the design requirements,and successfully complete the designated quality management objectives.
