A construction method for steel truss girder inspection vehicle track installation

Abstract

The invention relates to the technical field of rail installation of a steel truss girder inspection vehicle, in particular to a construction method for the installation of a steel truss girder inspection vehicle rail; the invention includes the following installation steps: construction preparation, installation of a temporary operating platform for the first section of the track, and installation of the first section Rails, installation of running devices, installation of remaining rails, removal of electric hoists and temporary operation platforms; compared with the traditional steel truss girder inspection vehicle rail installation and construction method, only the first section of rail needs to be installed by a crane, and other sections of rails are installed by electric The hoist, the traveling platform and the temporary platform can realize the continuous installation of the track. The whole construction method is relatively less affected by the weather, does not need to use the crane repeatedly, and has higher efficiency, better economy and operability.

Description

technical field [0001] The invention relates to the technical field of rail installation of a steel truss girder inspection vehicle, in particular to a construction method for the rail installation of a steel truss girder inspection vehicle. Background technique [0002] With the rapid development of my country's highway transportation infrastructure, steel truss girders play an increasingly important role in the transportation field. The harsh conditions such as strong wind, wave height, surge, strong typhoon, and complex geology are faced. Due to the harsh environment, it will bring challenges to the daily maintenance, maintenance and maintenance of the bridge in the future. Therefore, the steel truss girder must be set Bridge inspection vehicle. [0003] The traditional steel truss girder inspection trolley track installation method includes the method of transport ship + hoist. In practice, this construction method has the following disadvantages: First, the entire constr...

Problems solved by technology

[0003] The traditional installation method of steel truss girder inspection trolley track includes: transport ship + hoist. In practical application, this construction method has the following disadvantages: First, the entire construction process is greatly affected by the environment. , is greatly affected by the weather, the operation time is short, and the risk is also high. Secondly, every time a section of track is installed in this way, the winch and the operation platform need to be disassembled once, and the winch needs to be installed repeatedly by the crane, which will seriously affect The construction progress and the economy are also very poor

[0004] The method of hoisting by car crane, this method is mainly used for the installation of the upper chord track of the steel truss girder inspection trolley, has the following disadvantages: this method needs to often use the car crane to hoist the track, which is greatly affected by the construction environment and is not suitable for windy weather At the same time, the safety and economy are poor, and the construction efficiency is also very low.
