Subway tunnel anti-collapse structure and corresponding construction method thereof

Abstract

The invention belongs to the technical field of metro tunnel anti-collapse structures, and particularly relates to a metro tunnel anti-collapse structure and a corresponding construction method thereof.The metro tunnel anti-collapse structure comprises a base, a cavity is formed in the base, an electromagnetic plate is embedded in the cavity, and the electromagnetic plate is fixedly connected with a permanent magnet pressing plate through a plurality of reset springs; the permanent magnet pressing plates are slidably connected with the cavities, a plurality of sliding cavities are formed in the lower end of the base, inserting rods matched with the permanent magnet pressing plates are slidably connected into the sliding cavities, and clamping mechanisms matched with the inserting rods are arranged on the inner walls of the two sides of each sliding cavity. The supporting plate can be controlled to ascend and descend, then a user can adjust the height of the supporting plate according to needs, the device can control the permanent magnet pressing plate to collide with the inserting rods in a reciprocating mode so that the inserting rods can be rapidly inserted into the ground, and complexity and labor loss caused by manually knocking the inserting rods to be inserted into the ground are avoided.

Description

technical field [0001] The invention belongs to the technical field of anti-collapse structures for subway tunnels, and in particular relates to an anti-collapse structure for subway tunnels and a corresponding construction method. Background technique [0002] Tunnel is an engineering building buried in the ground, and it is 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 subway is a rapid , large-capacity, and electric traction rail transit, the trains run on fully enclosed lines, and the lines located in the central urban area are basically located in underground tunnels. [0003] At present, during the construction process of subway tunnels, anti-collapse structures are often used to support the top wall of subway tunnels to prevent landslides. The support plates on traditional anti-collapse structures are generally fixed on the support frame. During use, ...

AI Technical Summary

Problems solved by technology

[0003] At present, during the construction process of subway tunnels, anti-collapse structures are often used to support the top wall of subway tunnels to prevent landslides. The support plates on traditional anti-collapse structures are generally fixed on the support frame. During use, The height of the support plate cannot be adjusted according to the needs, which brings inconvenience to the use, and when the traditional anti-collapse structure is fixed, it is generally necessary to manually knock each insertion rod and insert it into the ground to realize the fixation of the anti-collapse structure. The whole process is more labor-intensive
