The mobile pumping station is located at the tunnel face and can move relative to the tunneling direction. The fixed pumping station is located at the completed secondary lining section of the tunnel. The external sedimentation tank is located outside the tunnel. The mobile pumping station and the fixed pumping station, as well as the fixed pumping station and the external sedimentation tank, are connected by pipelines. A temporary sump is provided at the tunnel face for temporarily collecting water accumulated inside the tunnel.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides two technical solutions:

[0026] Example 1: A comprehensive drainage and prevention device for karst water-rich tunnels, comprising:

[0027] The base frame 1 has reinforcing ribs on its surface, and a power supply device 2 is fixedly connected to one side of the top of the base frame 1.

[0028] Install the movable component 3. The bottom of the movable component 3 is fixedly connected to the top of the base frame 1. The movable component 3 is used for the quick installation and overall movement of the drainage pump.

[0029] The filter assembly 4 is fixedly connected at one end to the side of the installation and moving assembly 3. The filter assembly 4 is used to filter and maintain the dirt drawn in during the pumping process. With the installation and moving assembly 3, the pump body 36 can move quickly and stably. The mobile pump station is cleverly set at the tunnel face and has the ability to move flexibly along the tunnel face excavation direction. The pump body 36 is fixed by bolts 37. During installation, the pump body 36 can slide into the predetermined position through the track plate 31 and dovetail groove block 35 on the top of the base frame 1, which facilitates quick disassembly and assembly during maintenance.

[0030] Example 2 differs from Example 1 in that: a comprehensive drainage device for karst water-rich tunnels includes a movable component 3, which is fixedly connected to the top of the base frame 1. A movable rail sleeve 32 is slidably connected to the surface of the rail sleeve 31. A bearing plate 33 is fixedly connected to the top of the movable rail sleeve 32. A dovetail plate 34 is fixedly connected to the middle of the bottom of the bearing plate 33. A dovetail groove block 35 is movably fitted onto the surface of the dovetail plate 34. A water pump body 36 is fixedly connected to the middle of the top of the bearing plate 33. Bolts 37 penetrate the surface of the bearing plate 33. A telescopic rod 38 is fixedly connected to one side of the base frame 1 via a base. A handle 39 is fixedly connected to the top of the telescopic rod 38. Anti-slip protrusions are provided on the surface of the handle 39. Universal brake wheels 310 are provided at the bottom of the base frame 1. The filter component 4 includes a fixed frame 41 fixedly connected to the movable component 3. A sliding connection is made to the inner wall of the fixed frame 41. A movable plate 42 is fixedly connected to a spring 43 on one side. The spring 43 has a damper inside. The other end of the spring 43 is fixedly connected to the other side of the inner wall of the fixed frame 41. A round shaft 44 is rotatably connected to one side of the movable plate 42. One end of the round shaft 44 is fixedly connected to a clamping sleeve 45 through a connecting block. A U-shaped tube 46 is fixedly connected to the inner wall of the clamping sleeve 45. A filter screen 47 is fixedly connected inside the U-shaped tube 46. One end of the outer side of the U-shaped tube 46 is connected to the water inlet of the water pump body 36, and the other end is connected to an external pipe. Sealing rings are set at both ends. With the filter assembly 4, the device can effectively filter gravel in the tunnel water through the U-shaped tube 46 and the filter screen 47. The U-shaped tube 46 can be directly pulled apart from the top working pipe, which is convenient for workers to maintain on-site at the working face. The structure is simple and easy to operate.

[0031] The karst water-rich tunnel comprises a mobile pumping station, a fixed pumping station, and an external sedimentation tank. The mobile pumping station is cleverly positioned at the tunnel face and can be moved flexibly along the excavation direction, allowing for timely adjustments to the drainage layout based on the tunnel's progress. The fixed pumping station is located within the tunnel where the secondary lining (the second layer of support structure in tunnel lining, used to further reinforce the tunnel and improve its overall stability and safety) has been completed. The external sedimentation tank is located outside the tunnel, and all three are connected by pipelines.

[0032] A temporary sump is set up at the tunnel face to collect accumulated water from inside the tunnel. The sump is equipped with a primary water pump, and its outlet is connected to a drainage pipe leading to a mobile pumping station. This unique layout allows for efficient and rapid drainage of water from the tunnel, greatly reducing the adverse effects of water accumulation in the reverse slope tunnel on reverse slope construction and ensuring smoother construction.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, simply pull handle 39 to extend telescopic rod 38 to the appropriate length, pull base frame 1 and universal brake wheel 310 to roll, moving the entire device along with the working face. Turn on power supply 2 and water pump body 36, connect the drain pipe of water pump body 36 to the inlet of external fixed pump station through a pipe, and connect one end of U-shaped pipe 46 to suction pipe. Gravel and other debris in the accumulated water are filtered by filter screen 47 in U-shaped pipe 46 and will settle at the bottom of U-shaped pipe 46. After working for a period of time, pull down moving plate 42. Moving plate 42 drives the round shaft 44 and clamping sleeve 45 to move downwards. When the spring 43 is compressed, the round shaft 44 is rotated to 180 degrees, the clamping sleeve 45 and the U-shaped tube 46 are flipped, and the gravel and other debris in the U-shaped tube 46 fall directly into the garbage bag. Then, the bag is restored. After the water pump body 36 has been working for a period of time, the bolt 37 is rotated to separate the bolt 37 from the bottom of the base frame 1. Then, the sliding movement of the track sleeve 32 is made on the surface of the track plate 31, and the dovetail plate 34 is slid in the dovetail groove block 35. The water pump body 36 at the top of the dovetail plate 34 is directly disassembled. After the water pump body 36 is maintained, it is restored and continues to work. When the device has finished working, the device is restored.
