Study Of Construction Technology On Crts I Block Ballastless Track

Ballastless track is made of concrete or asphalt mixture instead of granular ballast track bed and the composition of the track structure type, and CRTS I type double block ballastless track is a kind of ballastless track structure designed by ourselves in our country. At present, the domestic construction of ballastless track in different ways, ballastless track construction technology research "this paper focuses on the rail frame method", by providing integrated set of ballastless track equipment, take corresponding construction technology, quality inspection standards, measurement methods and scientific number correctly according to the measures, improved the precision of orbit control and the slab construction quality; the innovation of construction technology of this study is to more than double block ballastless track "of traditional instrument method" construction technology to improve the construction precision level.No construction technology research track comprises a double block type I of CRTS ballastless track base plate construction, slab construction and construction organization scheme of three part logistics. The main research work and results:First of all, in the construction of double block type I of CRTS ballastless track base plate and slab as basis, the research and design of the slab "rail frame method" of the construction process, focusing on analysis of rail frame assembly, coarse, fine, coarse measurement system using efficient rail frame coarse, intelligent, automation, high precision track measuring instruments and advanced measurement technology for accurate harmonic measurement, improve the track construction process to adjust the speed and control precision.Secondly, aiming at the key factors of construction without track--Construction of logistics, to optimize the design of ballastless track construction logistics organization, formulated the ballastless track construction organization plan. Through the research on the logistics organization scheme, effectively ensure the construction material logistics and smooth, speed up the construction progress, is an important part of the construction process on the track without.Third, with the new Great Western Railway Passenger Station Project IV standard ballastless track project as "rail frame method" construction technology application, the optimization is no track engineering construction organization, management and good organizational measures, measures and economic measures, improves working efficiency, ensure the construction progress.Research on scientific research and the construction of combining production, from the construction practice and process test, continuous analysis summary, improve, improve, sums up the system of construction technology, concise and write technical documents used in the practice of production, improve the construction quality and efficiency. The research results of this paper has great reference value on ballastless track construction technology innovation.
