Abstract

The invention belongs to the technical field of repair of a ballastless track of a high-speed railway, and aims to provide a renovating method for gaps and mud spillover between a CRTSI template type ballastless track base plate and the surface layer of a roadbed of a high-speed railway, which can fundamentally solve the problems of gaps and mud spillover and guarantee the operating stability and the operating safety of the ballastless track. Grouting holes are drilled in the base plate, grouting pipes are mounted, and high polymer materials are poured into the grouting pipes, so that accumulated water between the base plate and the surface layer of the roadbed is absorbed, besides, crevices between the base plate and the surface layer of the roadbed are tightly stuffed, and the effects are good; enclosing holes are formed in side seams on two sides of the base plate, grouting pipes are mounted, enclosing materials are poured into the enclosing holes through the grouting pipes, and a tight water-blocking heavy curtain is formed on a crushed stone layer of the roadbed, so that water in the roadbed is prevented from penetrating into a part between the base plate and the surface layer of the roadbed, and phenomena of the gaps and mud spillover are prevented from occurring once again. The operation is precise, practical and economic, repair of gap damage between the base plate and the surface layer of the roadbed can be completed through limited skylight time, and the ride comfort of a line is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of ballastless track repair of high-speed railways, and in particular relates to a method for treating slurry leakage between a base plate of a CRTSI-type ballastless track and a surface layer of a roadbed. Background technique

[0002] Ballastless track is a form of low-maintenance track structure for high-speed railways. It uses reinforced concrete base plates instead of ballasted track beds to distribute and transmit wheel-rail forces to the subgrade foundation. Ballastless track has the characteristics of good track stability, continuity and smoothness, good structural durability, less maintenance workload, and long service life. Therefore, most of the high-speed railways we are building at this stage are based on ballastless track. The ballastless track is generally closed with sealing material to prevent water from penetrating into the track structure. When water infiltrates between the track base pla...
