Problems solved by technology

The traditional shield method construction has the disadvantage of high risk of overall shield hoisting
Due to the need to increase the temporary land acquisition for the installation of the shield receiving shaft, in areas without receiving conditions, the shield machine can only move forward and cannot retreat in the tunnel, and the receiving of the shield machine cannot be completed

Abstract

The invention discloses a method for disassembling an earth pressure balance shield machine in a tunnel. The method comprises the following steps: step 1, dismantling a cutterhead; step 2, dismantling a cylinder; step 3, dismantling a trolley; step 4, dismantling a screw conveyor; step 5, dismantling an erector; step 6, dismantling a motor and a reduction gear; step 7, dismantling a middle body structure; step 8, dismantling a masterdrive; and step 9, conveying the cutterhead out and cutting and dismantling the remaining structure. The invention provides the method for disassembling the earth pressure balance shield machine in the tunnel for a bored tunnel reverse-excavating shield receiving method, so that receiving of a shield machine is finished at a section without receiving conditions.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling, in particular to a method for dismantling an earth pressure balance shield machine in a tunnel. Background technique [0002] The Shield Method is a fully mechanized construction method in underground excavation construction. It propels the shield machine in the ground, and supports the surrounding rock through the shield casing and segments to prevent collapse into the tunnel. At the same time, a cutting device is used to excavate the soil in front of the excavation face, and it is transported out of the hole by the excavation machine, and the jack is used to pressurize and push in the rear, and the prefabricated segments are assembled to form a mechanized construction method of the tunnel structure. [0003] Compared with traditional construction methods, shield tunneling method is widely used in rail transit construction because of its high safety, fast construction speed and low cost...
