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

Embodiment

[0032] Example: as Figure 1-Figure 13 The shown anti-collapse tunnel construction disaster prevention and mitigation structure includes a support device 1 and a protection device 2. The protection device is installed on the support device 1, the support device includes a support frame 101, and the protection device 2 includes a support adjustment frame 204. Plate, slide assembly.

[0033] The support frame 101 is as figure 2As shown, two arched brackets 1011 are included. The two arched brackets are installed on the two bottom brackets 1012 according to the front and rear positions. The middle of each bottom bracket is provided with a long hole 1013 for the support adjustment frame 204 to pass through. An opening 1014 for installing the dust removal fan 217 is provided near the elongated hole, and a vertical plate 1015 for installing the supporting motor 201 is opened next to the elongated hole on a bottom bracket; the top center of the arched bracket is provided with an up...

Abstract

The invention discloses an anti-collapse tunnel construction disaster prevention and mitigation structure, which mainly relates to the technical field of tunnel construction, including a support device and a protection device, the protection device is installed on the support device, the support device includes a support frame; the protection device includes a support adjustment frame , lifting plate, sliding assembly; the support adjustment frame is used to control the support frame to contact the ground to carry out the support of the overall structure of the present invention; the main transmission rod is installed on the lifting plate, and the gear assembly is installed on the main transmission rod, and the first arc is driven by the gear assembly. The arc-shaped rack and the second arc-shaped rack move, the first arc-shaped rack and the second arc-shaped rack are fixedly installed with the left fender and the right fender respectively, and alarm sensors are arranged on the left fender and the right fender , When encountering a collapse, the alarm prompts at the first time; when the first arc-shaped rack and the second arc-shaped rack move, the sliding assembly is driven to slide on the support frame, expanding the protective space.

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 stratum and a form of human utilization 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 main buildings and Ancillary equipment is divided into two parts. The main building consists of a tunnel body and a tunnel door. Ancillary equipment includes vehicle shelters, firefighting facilities, emergency communication and drainage facilities. Long tunnels also have special ventilation and lighting equipment. During the construction of a cave tunnel, it is often necessary to use an anti-collapse support device to support the top of the tunnel. The current anti-collapse support device...
