Embodiment 1

[0047] Generally, the length of the receiving shaft of the shield machine in most subway construction stations is about 12 meters, with a net height of 7-8 meters and a net width of about 10 meters. The standard section of the station is about 120-200 meters long and 7 meters high and 7 meters wide. As long as the space design size can satisfy the passing capacity of the shield machine, the station passing trolley 2 can be used to pass the station. Taking the 15th mark of Xi'an Metro Line 4 as an example, the following is an introduction to the construction method of the shield machine using the station-passing trolley 2 to quickly pass through the station.

[0048] Scope of application: mainly for the subway stations that have been capped and the stations that have not reserved crane exits, the station passing trolley 2 is used to carry out the shield machine passing construction. The construction site has been capped, and the internal structure is narrow enough for the shie...

Abstract

Provided is a construction method of shield machine rapid station passing in small space. Through the use of an over station trolley and a shield machine, the rail is laid on the ground, and the over station trolley is erected on the rail. The trolley is provided with wheels, and walks on the steel rail, the resistance is small, and the directional control performance is good. Not only construction can be conducted in small space, but also the technical problems in the prior art of tedious construction, complex process and high labor intensity of workers are solved. The method is high in station passing efficiency, accurate in directional control, and the construction cost is low.

Description

technical field [0001] The invention relates to a construction method for rapidly passing a station, in particular to a construction method for rapidly passing a station in a small space of a shield machine. Background technique [0002] With the acceleration of urbanization, subway construction has become an indispensable part of urban construction. During subway construction, when the construction space is small, the application conditions cannot meet the normal starting of the shield machine. The existing non-negative ring starting construction method needs to hoist the shield machine equipment and mainly use concrete guide platform, which can only be applied to the starting stage and cannot be applied to the passing construction. In addition, the traditional crossing is to use the steel plate to move the shield machine. The friction resistance of the steel plate is relatively large and requires a lot of thrust, which makes the translation of the shield machine inflexible...
