Description

Technical Field

[0001] The invention belongs to the technical field of tunnel spraying and relates to a tunnel spraying fault early warning system. Background Art

[0002] A tunnel is a structure built underground, underwater or in a mountain for laying railways or building roads for the passage of motor vehicles. According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. Mountain tunnels are those that pass under mountains or hills to shorten the distance and avoid steep slopes; underwater tunnels are those that pass under rivers or on the seabed to cross rivers or straits; urban tunnels are those that pass underground in cities to meet the needs of railways passing through large cities. Of these three types of tunnels, mountain tunnels are the most commonly built.

[0003] After searching, a Chinese patent discloses a tunnel spraying device (authorization announcement number CN216518038U). The patent technology can conveniently and quickly adjust the spraying position and angle through the rotation of the turntable and the swing of the bottom adjustment arm and the end execution arm. However, during the spraying process, the pipeline is often blocked by cement slurry, resulting in the nozzle being unable to discharge slurry. If it is not discovered in time, it will affect the progress of the spraying operation. Therefore, a person skilled in the art provides a subject to solve the problems raised in the above background technology. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a tunnel shotcreting fault warning system, which solves the problem in the related art that during the shotcreting process, the pipeline is often blocked by cement slurry, resulting in the nozzle being unable to discharge slurry.
