Description

Technical Field

[0001] This invention belongs to the technical field of tunnel water and mud inrush sealing devices, and specifically relates to a tunnel water and mud inrush sealing device and method. Background Technology

[0002] The construction and use of tunnels face serious risks of geological disasters such as water inrush and mud inrush. In particular, water inrush and mud inrush disasters in deep-buried tunnels are often characterized by suddenness, large flow, and high water pressure. Once a disaster occurs, it may cause the tunnel to be flooded and construction to be interrupted, or it may cause significant casualties and economic losses. In some cases, projects may even be forced to stop construction or be rerouted. Most water inrush and mud inrush in tunnels occur in karst areas, and some occur in water-rich fault zones. Water inrush and mud inrush in tunnels is a phenomenon in which, during the tunnel construction process, due to the release of stress during tunnel excavation, groundwater in the aquifer overcomes the resistance of aquitards, faults, and fracture zones under the action of water head pressure, and suddenly rushes into the tunnel, enveloping mud and sand.

[0003] A search revealed a Chinese patent with publication number CN115596501A, which describes a device and method for sealing tunnel water and mud inrush. The invention states that when the two sides of the gathering plates rotate and gather the mud and sand together, some of the mud and water in the mud and sand will flow out through the filter cloth and water-permeable holes to the outside of the gathering plates.

[0004] However, the filtered water was not treated and dripped directly onto the tunnel floor, causing the surface to become wet, messy, and slippery, which increased the difficulty of construction for the workers. Summary of the Invention
