Problems solved by technology

[0006] Aiming at the deficiencies of the existing technology, the present invention provides a waterproof shield segment, which solves the problem that the traditional shield segment has poor ability to guide and divert the outer water flow, and it is easy to cause the soil above the shield segment to flow with water , which poses a threat to the stability of the shield segment, which is not conducive to the support and fixation of the shield segment, and the traditional water filtration equipment will be blocked after a long period of use underground, reducing the effect of water filtration

Abstract

The invention discloses a waterproof shield segment. The waterproof shield segment comprises a segment body, wherein an assembly clamping plate is fixedly connected to the top end of the segment body, mounting through holes are respectively formed in both ends of the surface of the assembly clamping plate, mounting bolts are respectively arranged on the left and right sides of the bottom of the segment body, a water diversion separation mechanism is arranged on the surface, which is close to the outer side, in the segment body, an inner conduction through pipe is arranged in the middle of the interior of the segment body, a liquid drainage guide pipe is arranged on the outer side, which is close to the lower part, in the segment body, and the output end of the bottom of the inner conduction through pipe communicates with the liquid drainage guide pipe. The invention relates to the technical field of shield segments. According to the waterproof shield segment, accumulated liquid is prevented from flowing to the inner side of the shield segment, and additionally, soil is isolated from liquid, so that the phenomenon that water and soil are lost because the soil flows along with the liquid is avoided.

Description

technical field [0001] The invention relates to the technical field of shield tunneling segments, in particular to a waterproof shield tunneling segment. Background technique [0002] The shield segment is the main assembly component of shield construction and the innermost barrier of the tunnel, which bears the role of resisting soil pressure, groundwater pressure and some special loads. The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel. [0003] For example, the Chinese invention publication number is: CN107762531A, a subway shield segment, including: sheet body, sheet ridge, upper boss, lower boss, through hole, bolt groove, first waterproof layer, second waterproof layer, butt joint The sheet body is an arc-shaped sheet body, with a ridge on the central axis of the inner surfac...
