Method for penetrating I-steel transverse beam in reinforcing process of jacking bridge and culvert line

Abstract

The invention discloses a method for penetrating an I-steel transverse beam in the reinforcing process of a jacking bridge and culvert line. The method comprises the following steps: setting a row of fixed pulley anchor columns, fixed pulleys, moving pulley set anchor columns, moving pulley sets and a windlass on the outer side of an existing line, winding a steel wire rope wound on the moving pulley sets and the fixed pulleys in a manual windlass rotating manner, enabling an I-steel transverse beam connected with the steel wire rope to penetrate into a transverse beam groove from a lower part, and the like. The method for penetrating the I-steel transverse beam in the reinforcing process of the jacking bridge and culvert line, which is disclosed by the invention, has the advantages that the power of the pulleys is taken, the mechanical principle is sufficiently utilized, construction convenience is achieved, the power and labor are saved, the penetration speed of the I-steel transverse beam is increased, the working efficiency is improved, running security of lines is ensured, and the like.

Description

technical field [0001] The invention belongs to the technical field of railway site construction, and in particular relates to a method for passing down I-shaped steel beams during the reinforcement process of jacking bridges and culverts. Background technique [0002] During the construction of jacking bridges and culverts, line reinforcement is a key process that has a great impact on the operation of existing lines. Therefore, how to improve the efficiency of existing line reinforcement has become an important issue for those skilled in the art. [0003] At present, the basic process of existing line reinforcement is: (1) mark the position of the I-beam beam at the construction site according to the requirements of the design drawings; (2) move the position of the concrete sleeper occupying the position of the I-beam beam; (3) Multiple beam grooves are excavated under the rail; (4) An I-beam beam is inserted into each beam groove; (5) Buckle rails and I-beam longitudinal ...

AI Technical Summary

Problems solved by technology

However, since the I-beam beam usually adopts I40b type I-beam, which is characterized by its own weight, the friction coefficient is high when penetrating the beam groove, and the required traction force is large, resulting in high labor intensity for the construction personnel.

In addition, because the reinforcement of the existing line is a labor-intensive process, usually affected by the construction site, the manual pulling force of the labor operation team cannot be fully utilized, so the work efficiency is low, and the pulling of the hoist is not completely controllable, which is likely to cause railway damage. The equipment is damaged, which brings safety hazards to railway traffic
