Automatic monitoring and early warning device for tunnel construction surrounding rock loosening circle deformation

Abstract

The invention discloses an automatic monitoring and early warning device for tunnel construction surrounding rock loosening circle deformation, and relates to the technical field of tunnel construction early warning, the automatic monitoring and early warning device comprises an early warning device body, the bottom of the early warning device body is movably connected with supporting legs, and one end of the top of the early warning device body is fixedly provided with an alarm. A warning lamp is fixedly connected to the upper portion of one side of the early warning device body, a level gauge is fixedly connected to the lower portion of one side of the early warning device body, and a control module is fixedly installed on the outer surface of the early warning device body. Through cooperation of the suckers and the limiting blocks, the suckers enlarge the contact area between the supporting legs and the ground, meanwhile, the adsorption force of the supporting legs to the ground is improved, the limiting blocks extrude the ground when the T-shaped rods are pressed, the sharp parts make full contact with the ground, the road holding force is improved, and the early warning device is prevented from toppling over; the problem that the early warning device is prone to toppling over on the unstable ground is solved, and the effect of preventing the early warning device from toppling over is achieved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction early warning, in particular to an automatic monitoring and early warning device for deformation of surrounding rock loose circles during tunnel construction. Background technique [0002] Tunnels are buildings built underground or underwater or in mountains, laying railways or building roads for the passage of motor vehicles. According to their location, they can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. A tunnel that passes under a mountain or hill to avoid a large ramp is called a mountain tunnel; a tunnel that passes under a river or under the sea in order to cross a river or strait is called an underwater tunnel; a tunnel that passes underground in a city to meet the needs of a railway passing through a large city is called a tunnel. For urban tunnels, the most built of these three types of tunnels are mountain tunnels. [0003] The...

Problems solved by technology

[0006] The invention provides an automatic monitoring and early warning device for the deformation of the surrounding rock loosening circle during tunnel construction. One of the purposes is to have the function of removing dust, so as to solve the problem that a large amount of dust will be generated during the tunnel construction, and the dust will affect the loosening of the surrounding rock during tunnel construction. The monitoring accuracy of the ring deformation automatic monitoring and early warning device leads to potential safety hazards; another purpose is to solve the problem that the tunnel construction surrounding rock loosening ring deformation automatic monitoring and early warning device cannot be placed horizontally, which will affect the measurement and even cause the early warning device to fall and damage parts. problems, in order to achieve the effect of protecting early warning devices and improving monitoring accuracy
