[0002] The tunnel floor refers to the bottom part of an underground tunnel or tunnel, also known as the channel bottom or tunnel bottom. In underground engineering, the tunnel floor usually refers to the bottom structure of the underground passage, which is used to support and carry the load of the passage, and plays the role of dispersing the load, protecting the foundation and providing traffic passage. The design and construction of the tunnel floor is very important because it needs to withstand the pressure from the ground, vehicles or other loads, while also ensuring the stability, safety and comfort of the passage. The design of the tunnel floor usually takes into account factors such as geological conditions, groundwater conditions, channel purpose, load requirements, etc. to ensure that the floor has sufficient bearing capacity and stability.

[0003] At present, the structure of the tunnel floor is simple, mostly a rectangular plate structure, and is fixed by pouring concrete during the installation process. After long-term use, the concrete connected to the tunnel floor may be damaged, causing the tunnel floor body to fall off, resulting in the structural instability and affecting the overall firmness. It is also inconvenient to disassemble and recycle, with high use costs, which reduces the use efficiency of the tunnel floor. Utility Model Content
