[0009] Preferably, the inner wall of the support column is provided with a cavity, and the sensor wire passes through the cavity of the support column to form a circuit connection with the alarm light.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model effectively solves the problem of insufficient stability of the tunnel through a multi-layer composite support structure. Specifically, through technical means such as grouting anchor rods and shotcrete, the rock mass around the tunnel is effectively reinforced, thereby enhancing the overall bearing capacity of the tunnel. At the same time, a high-strength steel mesh is used as the outer support to further improve the stability of the tunnel. In addition, adding a waterproof layer to the support structure, such as a polyvinyl chloride (PVC) waterproof board, not only plays a waterproof role, but also helps to improve the overall stability of the tunnel. These measures work together to significantly enhance the stability of the tunnel, ensure that the tunnel can resist various external pressures and deformations during use, and ensure the safe operation of the tunnel. At the same time, the pressure in the tunnel is relieved by support rods and support columns.

[0012] 2. The utility model sets up multiple monitoring points inside the tunnel and on the supporting structure. By establishing a complete monitoring system, real-time monitoring of parameters such as tunnel deformation, stress distribution and water pressure is realized. Sensors are installed in key positions, which can sense the internal conditions of the tunnel in real time and transmit the data to display devices such as alarm lights through sensor lines. This design enables tunnel managers to detect abnormal conditions in time and take maintenance measures quickly, thus avoiding potential safety hazards. At the same time, through the collection and analysis of real-time monitoring data, it can provide a scientific basis for the maintenance and management of the tunnel, help managers better understand the operation status of the tunnel and optimize the maintenance plan.
