[0032] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example:

[0034] like Figures 1 to 6 As shown, a drainage device for tunnel construction includes a separation box 2, which is hollow inside; and further includes:

[0035] The water inlet pipe 3 is arranged at the front end of the separation box 2, and the water inlet pipe 3 is fixedly connected to the separation box 2;

[0036] The drain pipe 1 is provided at the rear end of the separation box 2. The drain pipe 1 is fixedly connected to the separation box 2. A mounting groove 21 is provided on the separation box 2 at a position corresponding to the drain pipe 1.

[0037] The filter plate 5 is arranged in the mounting groove 21 and is connected to the separation box 2;

[0038] The stone discharge pipe 20 is arranged at the center of the bottom plate of the separation box 2, and the stone discharge pipe 20 is fixedly connected to the separation box 2;

[0039] There are two groups of vertical rods 8 and they are symmetrically arranged on the top of the inner wall of the separation box 2. The lower ends of the symmetrical vertical rods 8 are respectively connected to the central axis of the impeller 9 by bearings. The two ends of the central axis of the impeller 9 are respectively connected to the turntable 10. The edges of the symmetrical turntable 10 are respectively connected to the power round rods 15.

[0040] The mounting blocks 7 are provided with two groups and are symmetrically fixed on the left side inside the separation box 2. The upper ends of the symmetrical mounting blocks 7 are respectively connected with guide round rods 6, and a slidable slider 18 is provided on the guide round rod 6. A rotatable brush roller 17 is installed between the two groups of sliders 18 through a bearing. The brush roller 17 is in conflict with the filter plate 5. This design solves the problem that the existing device is not convenient for separating gravel in the water, and cannot store gravel in a centralized manner. At the same time, the filter plate 5 cannot be cleaned, and the filter plate 5 is easily blocked, resulting in poor drainage, which is not conducive to construction drainage.

[0041] In this embodiment, a transversely arranged U-groove 16 is fixed on the right side of both sets of sliders 18, and the power round rods 15 at both ends of the turntable 10 are inserted into the U-groove 16 and slidably connected thereto. This design facilitates the transmission of the rotational power of the turntable 10 to the slider 18 through the U-groove 16, thereby driving the brush roller 17 to move along the surface of the filter plate 5 to prevent the filter plate 5 from being blocked.

[0042] In this embodiment, a bucket-shaped convergence groove 11 is provided on the right side of the separation box 2, and the convergence groove 11 is located below the impeller 9. Short shafts 14 are fixedly connected to the front and rear sides of the convergence groove 11. The short shaft 14 is rotatably connected to the inner wall of the separation box 2 through bearings. Connecting rods 13 are rotatably connected to the front and rear end surfaces of the convergence groove 11. The upper end of the connecting rod 13 is rotatably connected to the L rod 12, and the other end of the L rod 12 is connected to the outer end of the power round rod 15. By adopting the rotatable connection method of the connecting rod 13, the reciprocating swing of the convergence groove 11 is achieved, which facilitates the collection of small gravel.

[0043] In this embodiment, a U-shaped limiting groove 19 is formed at the upper end of the stone discharge pipe 20. The left end of the convergent groove 11 is inserted into the U-shaped limiting groove 19. The convergent groove 11 has an inclined structure with the left side lower and the right side higher. The left end of the convergent groove 11 swings within the U-shaped limiting groove 19, facilitating the entry of crushed stone into the stone discharge pipe 20 through the U-shaped limiting groove 19 for discharge.

[0044] In this embodiment, the right end of the convergent groove 11 is configured as an arc-shaped structure and is in close contact with the inner wall of the separation box 2 to prevent crushed stones from falling through the gap therebetween.

[0045] In this embodiment, the position of the impeller 9 corresponds to the position of the water inlet pipe 3, and the central axis height of the impeller 9 is higher than the axis height of the water inlet pipe 3, which facilitates the water flow to impact the lower part of the impeller 9 and drive the impeller 9 to rotate.

[0046] In this embodiment, the height of the drain pipe 1 is lower than that of the water inlet pipe 3 to facilitate the discharge of water.

[0047] In this embodiment, support rods 4 that can be raised and lowered are respectively provided at the four corners of the bottom of the separation box 2. The design of the support rods 4 enables the entire device to be raised and lowered as needed to adapt to different construction environments.

[0048] In this embodiment, a detachable sealing cover is installed at the lower end of the stone-removing pipe 20. The sealing cover allows the lower end of the stone-removing pipe 20 to be easily disassembled and sealed, thereby facilitating drainage and gravel cleaning.

[0049] The working principle of this drainage equipment for tunnel construction is as follows: first, connect the water pump to the water inlet pipe 3 through a hose, then use the hose to connect the drain pipe 1 and the external water collection system, and use a sealing cover to block the lower end of the stone discharge pipe 20. Then start the water pump and use the water pump to make the accumulated water flow from the water inlet pipe 3 into the separation box 2, use the filter plate 5 to filter the impeller 5 to remove impurities in the accumulated water, and then drain the accumulated water from the drain pipe 1. During this process, the water flow hits the impeller 9, causing the impeller 9 to rotate. When the impeller 9 rotates, it collects the gravel in the water flow and transports the collected gravel to the convergence groove 11 below. The convergence groove 11 can swing back and forth as the impeller 9 rotates, making it convenient for the gravel to enter the stone discharge pipe 20 through the U-shaped limit groove 19 and finally realize the discharge of the gravel. The impeller 9 drives the turntable 10 to rotate, and the turntable 10 drives the power rod 15 to swing in the U groove 16. The power rod 15 drives the U groove 16 to move back and forth. The U groove 16 drives the slider 18 to move back and forth along the guide rod 6. The slider 18 drives the brush roller 17 to move back and forth along the surface of the filter plate 5 to clean the filter plate 5 and prevent the filter plate 5 from being blocked.

[0050] After the drainage is completed, a collection bucket is placed below the stone discharge pipe 20 , and the sealing cover is opened to allow the stones to be discharged through the stone discharge pipe 20 .

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
