Abstract

The invention discloses a shield cutter head overhaul working well support device and equipment and belongs to the field of foundation pit support. The device comprises a splicing type support structural body and a air-water isolation layer. The splicing type support structural body is an annular structure connected by a plurality of support structural units, a plurality of circumferential connecting component, and a plurality of pretightening components. The air-water isolation layer is spirally wound on the outer surface of the splicing support structural body from top to bottom and located between the outer surface of the splicing type support structural body and the inner wall of a working well. The lap joint width of the air-water isolation layer is not smaller than the height of a single-layer support structure steel piece. The invention further provides shield cutter head overhaul working well support equipment. The device is convenient to mount and demount, reusable, capable of isolating air and water by the air-water isolation layer and effectively removing underground water by a vacuum plastic pipe water descending device, simple in structure, convenient, easy to use, economical, environmental friendly, safe and efficient, and the lateral deformation of a foundation pit wall can be controlled effectively.

Description

technical field [0001] The invention relates to the field of support for working wells, in particular to a support device and equipment for working wells for shield cutter head maintenance. Background technique [0002] In recent years, the shield method is one of the most important methods for the construction of urban subway tunnels. During the tunnel construction process of shield tunneling method, it is often necessary to overhaul or replace the cutter (cutterhead), so the construction of the foundation pit (well) for shield cutterhead maintenance work is an indispensable part of the shield tunneling method. Compared with conventional foundation pits, the shield machine maintenance work pit (well) has many characteristics. For example, the plane size of the shield machine maintenance work well is relatively fixed. For common shield machines, it is generally a circle with a diameter of about 7 meters. The depth is relatively deep compared with trenchless construction (ho...
