Method for constructing underground space by shield-shallow buried covered excavation composite method

Abstract

The invention relates to a method for constructing an underground space by a shield-shallow buried covered excavation composite method, and belongs to the technical field of construction methods of the underground space. The construction method comprises the following steps of: constructing two or more shield tunnels in advance by a shield method; and excavating a soil body between the shield tunnels by a shallow buried covered excavation method. By the method, the construction of the underground space with a large cross section is safe and high-efficiency, a structure is definitely stressed, construction speed is high and construction cost is low. The method can be used for constructing large-scale underground spaces in various forms.

Description

The Construction Method of Building Underground Space by Shield Tunneling and Shallow Buried Underground Excavation Combined Method technical field The invention relates to a construction method for constructing an underground space. Background technique At present, the main methods of domestic urban underground space structure construction are open-cut method, shallow-buried underground method and shield method, but these three methods are restricted by the surrounding environment to varying degrees in the actual use process. (1) Open cut method In the case of the construction of underground space structures under the conditions of heavy traffic on the ground in the city, many surrounding buildings and many underground pipelines, traffic must be dredged or even interrupted, and pipelines must be relocated when necessary. In addition, during the construction process of open cut method, the demolition workload of ground structures is heavy, and the noise and vibration gene...
