Post-cast strip pouring supporting system and post-cast strip pouring construction method

Abstract

The invention provides a post-cast strip pouring supporting system and a post-cast strip pouring construction method, and belongs to the technical field of rail engineering. The post-cast strip pouring supporting system comprises a limiting side mold, an inserting plate and a supporting assembly. Technical effects are that: before the self-compacting concrete filling layer is poured, an insertingplate is arranged on the post-cast strip to block the previous self-compacting concrete filling layer, and the post-cast strip and the lower space of the next track plate form a communicating structure; when the post-cast strip is poured, pouring of the self-compacting concrete filling layer is synchronously achieved, pouring does not need to be conducted after the self-compacting concrete fillinglayer meets the strength requirement; the time difference between the post-cast strip and the next track plate is reduced, the construction efficiency is improved, and continuous line production canbe achieved; and meanwhile, the limiting side molds and the supporting assemblies are used for achieving position fixing and position adjusting of the inserting plates, the supporting assemblies can avoid steel bars between the adjacent track plates, the operability is high, the problem that a traditional end mold is difficult to take out is solved, the dismounting and mounting are easy and convenient, the turnover rate is high, and the construction difficulty is reduced.

Description

technical field [0001] The invention belongs to the technical field of track engineering, and more specifically relates to a post-cast tape pouring support system and a post-cast tape pouring construction method. Background technique [0002] Ballastless track has the characteristics of no ballast splash, good smoothness, good stability, long service life and good durability, and is more and more used in urban rail transit construction. Generally, the ballastless track includes a base, a self-compacting concrete filling layer and a track slab arranged in sequence, and the self-compacting concrete filling layer is arranged correspondingly to the circumferential contour of the track slab. In the construction stage, the gap area formed by the adjacent self-compacting concrete filling layer and the adjacent track slab is defined as the position of the post-pouring belt. [0003] In the construction process of the ballastless track, the base and multiple track slabs are set firs...
