Method for quickly adjusting elevation of rail embedded part
The invention relates to the technical field of rail traffic, and in particular relates to a method for quickly adjusting the elevation of a rail embedded part. The method comprises the steps that the lower part of a rail foundation is poured, and a plurality of vertical rods are inserted along the two sides of the rail foundation at intervals; vertical rods on the two sides of the rail foundation are each provided with a through long transverse rod in a welded mode, and the bottom elevation of the through long transverse rods is made to be consistent with the top elevation of the embedded part; the upper surface of the rail embedded part and the lower ends of the transverse rods are fixed through spot welding for acceptance inspection; a secondary grouting layer is poured out, and the through long transverse rods are dismantled; overlong vertical rods are cut, and the surface of the rail embedded part is cleaned and repaired. The method can use local materials, and is simple and easy to operate; the transverse rods are detachable, green and environment-friendly, and can be repeatedly used, so that the construction cost is reduced; rapid adjustment of the elevation of multiple rail embedded parts is facilitated, and the construction efficiency is improved; after the vertical rod are cut off, the exposed parts can play a role in anchoring reserved joint bars, and a cushion layer can be better bonded.
本发明涉及轨道交通技术领域，特别是涉及一种轨道埋件标高快速调整方法，包括如下步骤：浇筑轨道基础下部，沿轨道基础的两侧间隔插入若干根立杆；在轨道基础的两侧的立杆上分别焊接一根通长横杆，使通长横杆的底部标高与埋件的顶部标高一致；将轨道埋件的上表面与横杆的下端点焊固定，进行验收；浇筑出二次灌浆层，拆除通长横杆；切除过长立杆，清理修复轨道埋件表面；本方法能够就地取材，操作简单易行；横杆可拆除，绿色环保、能够重复利用，降低了施工成本；便于多个轨道埋件标高的快速调整，提高了施工效率；立杆切除后，外露部分能够起到预留插筋锚固作用，以便和垫层更好粘结。
