Description

Technical Field

[0001] The present invention relates to the technical field of tunnel safety construction, and in particular to a geological disaster early warning and protection system for tunnel construction. Background Art

[0002] Tunnel construction is an industry that is being vigorously developed by society. There are many harmful factors in tunnels that affect people's health. There are combustible materials such as coal and natural gas on some tunnel construction paths, and there may also be combustible gases such as gas in coal seams. During the tunnel construction process, the presence of natural gas and gas can easily lead to the risk of fire and explosion. Natural gas and gas pollute the air inside the tunnel and easily cause people to suffocate. The main components of natural gas and gas are methane, ethane, propane and hydrogen sulfide. At the same time, there are places prone to landslides on the tunnel construction path, and the geological hardness in some geological structures is low. These unstable factors pose a threat to the safety of construction workers.

[0003] The defects of the existing tunnel early warning system are:

[0004] 1. Existing technology CN211291565U discloses a dynamic monitoring and early warning system for tunnel construction. This technology does not have the function of judging the geological structure and hardness behind the tunnel face during tunnel construction, resulting in people being unaware of dangers during tunnel construction. Therefore, a geological disaster early warning and protection system for tunnel construction that can easily detect the geological structure and hardness behind the tunnel face is needed to solve this problem.

[0005] 2. Existing technology CN108643930A discloses a real-time early warning method for TBM tunnel construction. This technology does not have the function of detecting the size of voids in the geology behind the tunnel face, which makes it inconvenient for people to analyze the geological structure. Therefore, a geological disaster early warning and protection system for tunnel construction that can measure the pore size in the geology behind the tunnel face is needed to solve this problem.

[0006] 3. The prior art CN114485570A discloses a system and method for intelligent monitoring, measurement and early warning of construction safety in tunnels under construction. This technology does not have the function of detecting whether there is combustible gas in the geology behind the tunnel face. When combustible gas exists behind the tunnel face, blind construction will cause a large amount of combustible gas to exist in the tunnel, which is dangerous. Therefore, a geological disaster early warning and protection system for tunnel construction that can detect whether there is combustible gas in the geology behind the tunnel face is needed to solve this problem.

[0007] 4. Prior art CN119244316A discloses a method and system for monitoring rockburst risks during tunnel construction. This technology does not have the function of detecting whether there is combustible gas in the geology behind the tunnel face. When a drilling rig is used to drill the tunnel face to determine the geological structure behind the tunnel face, if combustible gas escapes through the drill hole, it is easy to cause danger. Therefore, a geological disaster early warning and protection system for tunnel construction that can seal the holes drilled on the tunnel face is needed to solve this problem.
