A kind of equipment for single-track tunnel inverted arch construction

Abstract

The invention discloses a device for invert construction of a single-line tunnel, which comprises a horizontally stable fixed base plate and a vertically connected support column, and both sides of the top of the horizontally stable fixed base plate are fixedly connected to the bottom ends of the vertically connected support column , the top end of the vertically connected support column away from the horizontally stable fixed bottom plate is fixedly connected with a horizontally stable top plate. The present invention relates to the technical field of inverted arch construction. The equipment used for single-line tunnel inverted arch construction enables the device to drive the rolling wheel to move on its own or on the track surface under the rotation of the auxiliary motor, thereby realizing the on-site stirring of the maintenance liquid on the working surface, and the new mixed maintenance liquid is effective. It greatly improves the functionality of the maintenance liquid, avoids the problems of unevenness and low efficiency of manual on-site modulation, greatly enhances the maintenance effect, effectively guarantees the use function of the maintenance bench, and improves the safety of the maintenance bench sex.

Description

technical field [0001] The invention relates to the technical field of inverted arch construction, in particular to a device for invert arch construction of a single-line tunnel. Background technique [0002] The inverted arch is a reverse arched structure set at the bottom of the tunnel to improve the stress conditions of the upper support structure. It is one of the main components of the tunnel structure. The load on the road surface can be effectively transmitted to the ground, and it can also effectively resist the reaction force from the lower layer of the tunnel. The inverted arch and the secondary lining constitute the tunnel as a whole, which increases the structural stability (the maintenance platform is cleaned and maintained by non-destructive preparation of the mixed solution, reducing the oxidation and corrosion of the platform and improving the service life). [0003] During the normal inverted arch construction on the tunnel site, it is often necessary to su...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a device for single-line tunnel inverted arch construction, which solves the need to support large-scale maintenance benches inside the tunnel for auxiliary work when performing normal inverted arch construction on the tunnel site. The construction is carried out by personnel, and the construction environment inside the tunnel is extremely harsh. The maintenance platform is not maintained in the traditional construction process. The iron maintenance platform is very easy to be oxidized and corroded. The platform will be damaged if it is used for a long time, and the construction cost is relatively high. question
