Novel plate anchor structure

Abstract

The invention discloses a novel plate anchor structure. The plate anchor structure includes corrugated plates and expansion bolts. The corrugated plates are anchored on the inner surface of a lining through a bolt structure. One ends of the upper corrugated plates and one ends of the lower corrugated plates are overlapped at the connection of the adjacent two corrugated plates. The wave peaks of the upper corrugated plates and the lower corrugated plates are connected and fixed to the lining surface by the expansion bolts. The novel plate anchor structure has the beneficial effects that the tensile bending and compressive shear properties of the lining can be effectively enhanced, and the further development of lining cracks can be effectively inhibited; and the corrugated plates can forma drainage channel similar to a water channel in a wave trough area that is separated from the lining structure, the leakage water of the lining drained to ditches on both sides, so that it is ensuredthat a rich water tunnel has sufficient drainage capacity, and the adverse effects of the lining structure cracking is minimized. According to the novel plate anchor structure, by changing the relevant design parameters of the corrugated plates, the reinforcement and repair of different degrees for different lining crack conditions can be realized.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering and relates to a novel plate anchor structure. Background technique [0002] With the development of engineering equipment and technology, tunnels have gradually become a common architectural form. The tunnels that have been built in my country are limited by the survey methods, design technical standards and construction technology levels at that time due to the different construction years, coupled with the differences in engineering hydrogeology, etc. After decades of operation, most of the tunnels have been affected Diseases of railway operation safety such as tunnel water leakage, lining cracks, frost damage and lining corrosion. The commonly used methods for strengthening the tunnel structure in the prior art schemes include methods such as bolt-spray reinforcement, W-steel strip reinforcement, and pasting of fiberboard reinforcement to reinforce the tunnel. In the tunnel disease...

AI Technical Summary

Problems solved by technology

Although the above-mentioned maintenance method is a common method for strengthening tunnels at present, it still has certain limitations. Not only the construction process is relatively cumbersome, the construction period is long, and some measures need to occupy a large tunnel clearance

In addition to the above limitations, conventional repair measures cannot solve the problem of tunnel water leakage well
