Method for quickly adjusting elevation of rail embedded part

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method for quickly adjusting the elevation of rail embedded parts. Background technique [0002] With the advancement of production technology, handling equipment is usually used in modern production workshops to cooperate with rails for material transportation, for example, straddle cars, ladle cars, transport cars, battery cars, etc., the basic rails are almost in the form of one-step caps. For a shaped foundation, when the design adopts the method of setting embedded parts to fix the foundation track, ensuring that the elevation of the foundation embedded parts is consistent is a problem that needs to be paid attention to when setting the embedded parts. [0003] Usually, the current practice is to set up brackets separately under each embedded part or directly weld and fix the embedded parts with the foundation steel bars. However, when setting up brackets separately, ...

Problems solved by technology

[0003] Usually, the current practice is to set up brackets separately under each embedded part or directly weld and fix the embedded parts with the foundation steel bars. However, when setting up brackets separately, there are many brackets, and it is very troublesome to ensure that the elevation of each embedded part is consistent. The method of welding and fixing the embedded parts and the foundation steel bars has the disadvantages of low rigidity and easy deformation of the foundation steel bars, and the embedded parts are prone to displacement when pouring concrete
