Study On The Quality Control Method Of Mechanized Maintenance Construction Of Railway Engineering Project

With Chinese railways development, the requirement for aualitv is increasing higher. At present, the domestic repair and maintenance of the railway line has been widely used in large maintenance machinery for construction operations. Kunming Railway line have some bridges, tunnels and more with the design slope, small curve radius situation, repair and maintenance is very difficulty. study on the quality control method of mechanized maintenance construction of railway engineering project, which can substantially improve the quality and efficiency of maintenance operations.This paper introduces large track maintenance machinery construction quality control Principle, analyzes the impact of large maintenance machinery maintenance Road mattress knot, the lack of ballast, sleepers irregular spacing of unfavorable factors, diseases such as rail, set forth in a seamless and seam line, the line and the station line, automatic block section and semi-automatic block section, bridges and general lines, day and night, before and after the section of the line with the turnout, differences under different conditions of construction and engineering lines existing lines.Explore the use of measures and methods to large maintenance machinery in line maintenance tamping, tamping turnouts, rail grinding, dynamic stability and other construction operations to improve operational efficiency, control construction costs, improve quality and other aspects of the job.Content of Large Maintenance Machinery construction organization, operating procedures and requirements, construction coordination and other aspects of emergency response, and actual construction cases demonstrate, So eliminate the interference of various factors, choose a reasonable way construction organization, and strictly control the construction process to improve operational efficiency, control of construction quality, reduce maintenance costs with a strong practical significance, improve Railway maintenance operations and quality control to provide reference.
