Problems solved by technology

Construction enterprises without military beams are all specially manufactured, which not only increases investment, but also is inconvenient to use
Compared with the prefabricated bedding method, the cover-and-excavation method currently used in my country requires a large number of temporary supports. The manufacture and use of these temporary supports are not standardized, and there are many unreasonable points in the design calculation method and the structural form of the support. Too safe, wasting materials and increasing construction costs

Abstract

The invention discloses a method for building a subway station, and the method comprises the following construction steps of: sorting underground pipelines, and carrying out diversion on the pipelines needing diversion; modifying traffic guide; constructing a foundation pit enclosure structure; constructing a cover system, and taking part of a constructed cover plate as a half cover part; recovering a temporary pavement on the constructed cover plate; excavating a foundation pit, carrying out suspension treatment on the pipelines which are not moved away, and transporting the soil body excavated from the open cut part out from the foundation pit; constructing a main body structure of the station, and lifting material and constructors to pass in and out from the open cut part; and backfilling earthwork, dismounting the cover system and recovering a pavement.

Description

technical field [0001] The invention relates to a subway station construction method in underground engineering, in particular, the invention relates to a construction method suitable for constructing a subway station in a city. Background technique [0002] In the construction of urban subway stations in my country, the cover-excavation method, open-cut method and mine method are mostly used for construction. When using the open cut method, the problem of dust is serious, affecting the environment and traffic. When the cover-excavation method is used for construction, because there is no standard temporary pavement pavement components, military beams and temporary steel plates are used instead. Construction enterprises without army beams are all specially manufactured, which not only increases investment, but also makes it inconvenient to use. Compared with the prefabricated bedding method, the cover-and-excavation method currently used in my country requires a large numb...
