Problems solved by technology

Although the support area can be adjusted in this patent, the support panel in this patent can only form a support plane in the axial direction of the tunnel, and the support angle cannot be adjusted in the circumferential direction of the tunnel, nor can it be supported on both sides of the tunnel wall. The adjustment and deployment mechanism cannot notify the construction personnel at the first time in case of danger

Abstract

The invention discloses a collapse-prevention tunnel construction disaster prevention and reduction structure, and mainly relates to the technical field of tunnel construction. The collapse-prevention tunnel construction disaster prevention and reduction structure comprises a supporting device and a protection device, wherein the protection device is mounted on the supporting device; the supporting device comprises a supporting frame; the protection device comprises a supporting adjusting rack, a lifting plate and a sliding assembly; the supporting adjusting rack is used for controlling the supporting frame to be in contact with the ground so as to support the whole structure; a main transmission rod is mounted on the lifting plate; a gear assembly is mounted on the main transmission rod; the gear assembly drives a first arc-shaped rack and a second arc-shaped rack to move; the first arc-shaped rack and the second arc-shaped rack are fixedly mounted with a left protection plate and a right protection plate respectively; alarm sensors are arranged on the left protection plate and the right protection plate; when collapse occurs, an alarm prompt is given at the first time; and when the first arc-shaped rack and the second arc-shaped rack move, the sliding assembly is driven to slide on the supporting frame, so that the protection space is expanded.

Description

technical field [0001] The invention mainly relates to the technical field of tunnel construction, in particular to a collapse-proof tunnel construction disaster prevention and mitigation structure. Background technique [0002] Tunnels are engineering buildings buried in the ground, and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and military tunnels. The structure of the tunnel includes the main building and There are two parts of auxiliary equipment. The main building is composed of the cave body and the cave door. The auxiliary equipment includes car shelters, fire-fighting facilities, emergency communication and waterproof and drainage facilities. The long tunnel also has special ventilation and lighting equipment. During the construction of cave tunnels, it is often necessary to use anti-collapse support devices to support the top of the tunnel. The current anti-collapse ...
