Abstract

An embodiment of the present invention provides a method for opening a shield machine under normal pressure. The method for opening a shield machine under normal pressure includes the following steps: setting a plurality of hollow piles arranged at intervals along a preset direction at a preset opening position, Among them, the preset direction has an included angle with the tunneling direction of the shield machine; the shield machine tunnels to the preset opening position, and the cutter head of the shield machine extends into multiple hollow piles; the multiple hollow piles are located on the outermost side The two hollow piles are respectively the first hollow pile and the second hollow pile, and the orthographic projection of the front end face of the cutter head along the direction parallel to the axis of the hollow pile has a first part located in the first hollow pile and a first part located in the second hollow pile. In the second part, the length of the first part is different from the length of the second part; open the warehouse at normal pressure. The opening of the shield machine under normal pressure has high safety, and there is enough room for movement to carry out the inspection and maintenance of the shield machine.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a method for opening a shield machine under normal pressure. Background technique [0002] During tunnel construction, after the shield machine is driven to the set position, it is necessary to overhaul or maintain the shield machine to ensure that the shield machine can work normally. Before the shield machine needs to be inspected or maintained, it is necessary to stop the excavation operation of the shield machine at the set position, so that the shield machine can be opened, so that maintenance personnel can enter the shield machine for inspection or maintenance. [0003] The inventors found that the existing shield machines have at least the following disadvantages when they are overhauled or repaired: [0004] There are few parts of the shield machine exposed to the external environment, so it is not easy to overhaul or repair. Contents of the invention [0...
