Track slab banding and pressing process for plate-type ballastless tracks

Abstract

The invention discloses a track slab banding and pressing process for plate-type ballastless tracks. In the invention, banding and compaction construction can be carried out on multiple sections from front to back. The construction process is as follows: 1, crosswise banding of track slabs: supporting a vertical board, filling narrow seams to be compacted, laying exhaust pipes and completing the banding process of all the narrow seams in the constructed ballast bed slab sections; 2, longitudinal banding of the track slab: laying out, compacting and fixing a left longitudinal banding device and a right longitudinal banding device and completing the longitudinal banding process of all concrete ballast bed slabs in all of the constructed ballast bed slab sections; and 3, completing the banding and pressing process of all track slab sections in the ballastless track bed slabs. The process disclosed by the invention has the advantages of reasonable design, simple process steps, good using effect and high construction quality, and is convenient to realize, and the problems that the existing track slab banding and pressing process for the plate-type ballastless tracks has complicated process steps, low efficiency of construction, difficultly in construction quality control, high level of pollution to the environment and the like can be solved.

Description

technical field [0001] The invention relates to the technical field of construction of comfortable and ballastless track, and in particular relates to a track plate edge sealing and compaction process of a slab ballastless track. Background technique [0002] In recent years, with the large-scale construction of passenger-dedicated railways in my country, CRTSⅡ ballastless track has been more and more widely used. One of the key technologies, it is a key process to ensure high precision and high smoothness of the track. The track slab laying accuracy control is the core technology in the track slab laying process. If the control is not proper during the construction process, the track slab laying accuracy will be low, which will increase the difficulty of track fine adjustment and the amount of fastener rework in the later stage, which will not only cause Huge pressure on the construction period, and will greatly increase the construction cost of the project. At present, mo...
