AI Technical Summary

Technical Problem

In the prior art, water seepage in the rock wall during the construction of the shield causes sludge and impurities to block the drainage hole, affecting the normal use of drainage equipment, causing water to accumulate in the hole, and affecting the safety of the machine.

Method used

A drainage equipment for top shield construction is designed, including construction pipelines, drainage beds, drainage chambers, drainage holes and drainage rings. Through the design of the drainage ring, the water flow is filtered and guided through the water guide tank and drainage channel to prevent silt and sand from being blocked, while providing a convenient cleaning method.

Benefits of technology

It effectively prevents the drainage hole from being blocked, ensures the normal use of drainage equipment, prevents water accumulation, and ensures the safety of the machines in the hole.

Abstract

The utility model discloses drainage equipment for top shield construction, and relates to the technical field of top shield construction, the drainage equipment comprises a construction pipeline, the inner ring surface of the construction pipeline is fixedly connected with a drainage bed, in the drainage equipment, a mounting sleeve block can be detached through a bolt, meanwhile, an inserting groove is separated from the drainage bed, and a drainage ring can be detached from the inner wall of the construction pipeline. Silt accumulated on the inner wall of the drainage ring can be conveniently cleaned, the first drainage hole and the second drainage hole are prevented from being blocked to affect drainage, the safety of a machine in a hole is guaranteed, and during drainage, a water guide groove and a drainage channel are formed in the drainage ring, so that water flow in a construction pipeline can be guided; the drainage ring is arranged in the construction pipeline, water flow is guided into the second drainage hole through the interior of the drainage ring and then enters the drainage cavity, meanwhile, water in the construction pipeline enters the drainage cavity through the first drainage hole and is uniformly collected into the first drainage pipe to be drained, and drainage of the interior of the construction pipeline is facilitated.
