[0002] A tunnel is an engineering structure buried in the stratum, which can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and military tunnels. When a tunnel is excavated, water leakage or water gushing may occur at the fault fracture zone. At this time, it is necessary to drain the water in time to avoid affecting subsequent construction.
[0003] After retrieval, the utility model patent with the publication number of CN220621962U discloses a drainage device for tunnel construction, including a carrier vehicle. It is characterized in that a support frame is installed on the carrier vehicle, rotating shafts are symmetrically and rotatably installed at the top ends of the support frame, a water collecting cover is fixedly installed between the inner surfaces of the two rotating shafts, a water storage tank is fixedly installed on the upper surface of the carrier vehicle, a water guide pipe is installed between the water drainage port of the water collecting cover and the water storage tank, a water pump is fixedly installed on the upper surface of the carrier vehicle, a water suction pipe is installed between the water inlet end of the water pump and the water storage tank, a water discharge pipe is installed at the water outlet end of the water pump, support plates are fixedly installed on the front and rear surfaces of the support frame, and an angle adjusting device is installed on the upper surface of the front support plate and is connected to the front rotating shaft; this patent can use the lifting of the support frame to buckle the water collecting cover at the water leakage or water gushing place on the tunnel wall for collection, and the drainage process can bypass the tunnel ground, thus ensuring the construction operation environment.
[0004] However, the above patent still has the following deficiencies: The water collecting cover is located above the carrier vehicle.

[0028] In this embodiment, the water falling from the tunnel leakage or water gushing place is filtered by the filter holes on the arc-shaped filter screen 17 to prevent sand and gravel from falling into the water guiding hose 14 and causing blockage. In addition, the sand discharging cylinder 16 is inclined and arranged outside the water guiding cylinder 11 to prevent water from being discharged from the sand discharging cylinder 16, so that the water can only be introduced into the water storage tank 13 from the water guiding hose 14 under its own weight.

[0036] In this embodiment, the top surface of the truncated cone plate 4 is used to support the telescopic cylinder 7 to ensure the water connection strength of the telescopic cylinder 7 to the extension column 9, the fixing ring 10 and the water collecting cover 12, and also to ensure the stability of the extension column 9 in the telescopic cylinder 7.
[0037] Working principle: When in use, first hold the push handle 25 to push the device to move in the tunnel, so that the water collecting cover 12 is located below the water leakage or water gushing in the tunnel to collect water. When the water collecting cover 12 is not convenient to move to the bottom of the water leakage or water gushing, start the first motor 6 to drive the telescopic cylinder 7, the extension column 9 and the water collecting cover 12 to rotate horizontally, and at the same time start the second electric hydraulic rod 8 to drive the extension column 9 to extend and retract on the telescopic cylinder 7, thereby changing the horizontal position of the water collecting cover 12, so as to adjust the water collecting cover 12 to the bottom of the water leakage or water gushing, and then start the first electric hydraulic rod 2 to drive the lifting frame 3, the telescopic cylinder 7 and the water collecting cover 12 to move upward. , use the water collecting cover 12 to receive the water in the tunnel, and the water is introduced into the inner cavity of the water storage tank 13 from the water guide tube 11 and the water guide hose 14 below the water collecting cover 12. In addition, start the water pump 23 to discharge the water in the inner cavity of the water storage tank 13 from the drain pipe 24 to the outside of the tunnel. Finally, when receiving the water, use the arc filter screen 17 in the inner cavity of the water guide tube 11 to filter the sand and gravel in the water. In addition, use the second motor 19 to drive the spiral feed rod 20 to rotate. The rotation of the spiral feed rod 20 drives the sand and gravel on the arc filter screen 17 to tilt upward. When the sand and gravel move to the top of the sand outlet pipe 18, the sand and gravel fall from the sand outlet pipe 18.
