Problems solved by technology

[0002] At present, in the process of TBM construction, its transportation guarantee is an important process to ensure the tunneling construction of TBM, and the meeting platform is an important configuration in the transportation process. Therefore, the existing TBM will be equipped with a two-way meeting platform. The installation of the car platform is particularly important for the construction project of single-track transportation in long tunnels. At present, the main method of installing the car meeting platform is to use the drill and blast method to excavate a step-in hole that meets the length of the TBM and the car meeting platform. The TBM is assembled at the same time; the installation of the meeting platform in this way, the assembly site and the length of the step-in hole must be completed before the TBM is assembled. The time limit is tight, and the cost of drilling and blasting is relatively high.

Abstract

The invention discloses a method for installing a trailer on a TBM meeting platform. The method includes the following steps: 1) construction preparation; 2) installing an electric crane; 3) stopping excavation; 4) supporting a tail drag plate after separation; 5) installing 6) Transportation of the meeting platform outside the cave; 7) Transportation of the meeting platform inside the cave; 8) Installation of the meeting platform; 9) Connection of the meeting platform; 10) Assembly completed. The invention has the advantages of flexible and convenient installation and reliable operation. Adopting it can not only reduce manual push and save labor, but also facilitate fine adjustment of the meeting platform, thereby reducing the installation error of the meeting platform and improving the assembly of the meeting platform At the same time, the method also shortens the assembly time, saves equipment costs, reduces costs, and improves safety performance.

Description

technical field [0001] The invention relates to the field of TBM construction, in particular to a method for installing a trailer on a TBM meeting platform. Background technique [0002] At present, in the process of TBM construction, its transportation guarantee is an important process to ensure the tunneling construction of TBM, and the meeting platform is an important configuration in the transportation process. Therefore, the existing TBM will be equipped with a two-way meeting platform. The installation of the car platform is particularly important for the construction project of single-line transportation in long tunnels. At present, the main method of installing the car meeting platform is to use the drill and blast method to excavate a step-in hole that meets the length of the TBM and the car meeting platform. The TBM is assembled at the same time; the installation of the meeting platform in this way, the assembly site and the length of the step-in hole must be compl...
