Abstract

The invention discloses a trailer mounting method for a TBM meeting platform. The method includes the following steps of (1) construction preparation, (2) mounting of an electric hoist, (3) stopping of tunneling, (4) matching of a tail carriage after separation, (5) mounting of a variable-slope track, (6) transportation of an outside meeting platform, (7) transportation of an inside meeting platform, (8) mounting of the meeting platforms, (9) connection of the meeting platforms and (10) completion of assembling. The method has the advantages of flexible and convenient mounting manner and reliability in operation, with the adoption of the method, manual pushing can be reduced, the labor can be saved, and fine adjustment can be performed on the meeting platforms conveniently, so that mounting errors of the meeting platforms can be reduced, and the assembling quality of the meeting platforms can be improved; and meanwhile, with the method, the assembling time is further shortened, the equipment cost is saved, the cost is reduced, and the safety performance is improved.

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...
