Abstract

The invention discloses a shield transverse moving station crossing method, and belongs to the technical field of shield construction. The problems that in the prior art, a transverse moving station crossing device is large in transverse moving difficulty of a shield tunneling machine, operation is not convenient, and construction efficiency is low are solved. The method comprises the following steps of S1, construction preparation; S2, putting of the shield tunneling machine (1) on a bracket (20); S3, transverse moving of the shield tunneling machine (1); S4, longitudinal moving of the shieldtunneling machine (1); and S5, in-place operation of the shield tunneling machine (1). Through cooperation of a lifting hydraulic cylinder and a bracket transverse moving hydraulic cylinder, transverse moving of the shield tunneling machine can be conveniently carried out, the operation process is simple, construction efficiency can be improved, construction cost is saved, and the method is suitable for shield station passing construction.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling, and in particular relates to a method for shield tunneling to move over stations in translation. Background technique [0002] With the development of the city, the urban underground rail transit is becoming more and more mature, and the shield tunneling method is currently the safest tunnel construction method in tunnel construction. In subway construction, there are many stations and short intervals. In most cases, the shield machine needs to pass through one or more stations. Due to the large size of the shield machine, passing the station is a difficult problem in shield tunneling construction. [0003] At present, the traditional shield tunneling methods mainly include dismantling, hoisting and moving. Dismantling and lifting requires frequent hoisting in and out, as well as dismantling, secondary assembly, and secondary commissioning of the shield machine and supporting equipment,...
