Segment caulking and hand hole blocking trolley for large-diameter shield tunnel

Abstract

The invention discloses a segment caulking and hand hole blocking trolley for a large-diameter shield tunnel, which comprises an arched frame. The arched frame is of an arch shape, the middle part of the arched frame is provided with a through chamber, the bottoms of the two sides of the arched frame are provided with universal wheels, universal wheel clamping plates are arranged on the universal wheels, the upper part of the arched frame is provided with a top construction platform, and the two sides of the arched frame are respectively provided with a side construction platform. The invention has the advantages of: overcoming the defects of the prior art, reducing the construction input and improving the construction efficiency since the mobile trolley can move along with the progress of works; realizing the all-round construction of the top part of the tunnel within 162 degrees and satisfying the construction requirements; due to the arched frame of an arch shape, ensuring the normal transportation of tunnel materials; making the construction safe, eliminating safety risks of the overhead operation, and ensuring the smooth progress of the works; and simplifying the structure and the like.

Description

Technical field [0001] The invention relates to the field of large-diameter shield tunnel construction, in particular to a large-diameter shield tunnel segment caulking and hand hole blocking trolley. Background technique [0002] At present, during the construction of large-diameter shield tunnel segment caulking and hand-hole plugging, the establishment of the construction platform has a major impact on the progress and safety of the project. Especially in the tunneling process of the shield machine, it is necessary to carry out simultaneous construction of segment caulking and hand hole plugging. The range of segment caulking and hand hole treatment: circular seams, longitudinal seams and hand holes within 162 degrees of the top of the tunnel. The existing construction method is to set up scaffolding in the tunnel, and then the construction personnel stand on the scaffolding to construct. The problems in the construction process are: [0003] 1. The erected scaffolding will bl...

AI Technical Summary

Problems solved by technology

[0003] 1. The erected scaffolding will block the traffic in the tunnel and cannot guarantee the normal transportation of materials in the tunnel;

[0004] 2. Use the conventional method of erecting scaffolding for construction. As the construction continues, it is necessary to repeat the process of erecting scaffolding, dismantling, changing the work site, and re-establishing. Repeatedly, it requires a lot of manpower and material resources, and the construction efficiency is low.
