[0026] Embodiment 1: This embodiment aims to propose a flood discharge culvert for a tailings pond.

[0027] According to Figures 1 to 4 As shown, it includes a construction main body and a tunnel base soil layer 1;

[0028] A tunnel that is transparent from front to back is dug inside the construction main body. The bottom of the tunnel is the tunnel base soil layer 1. A plurality of arched supports 2 are inserted on the tunnel base soil layer 1. The arched supports 2 are arranged along the front-rear direction. Arch-shaped concrete linings 3 are poured between the arched supports 2. In this embodiment, the arch-shaped concrete lining 3 is formed by welding a steel reinforcement cage between two adjacent arched supports 2 and then pouring concrete into the steel reinforcement cage.

[0029] The arched support 2 and the concrete lining 3 form a support arch roof, and secondary reinforcement is carried out on the inner wall of the support arch roof by concrete spraying.

[0030] The tunnel base soil layer 1 located inside the support arch roof is paved with a concrete pouring layer 4. In this embodiment, the concrete pouring layer 4 is laid by laying a steel reinforcement cage and then pouring concrete. A waterproof layer 5 is laid on the concrete pouring layer 4. The waterproof layer 5 can be made of waterproof materials. Common waterproof materials include polymer modified asphalt waterproof coiled materials, cement-based waterproof materials, etc.

[0031] An interceptor 6 is provided on the waterproof layer 5. The interceptor 6 is inclined forward from bottom to top. The interceptor 6 seals the water inlet of the tunnel. The interceptor 6 includes a mounting frame 601. A rotating frame 602 is hinged on the mounting frame 601. The upper surface of the rotating frame 602 is fixedly connected with an intercepting grille 603 extending vertically. The intercepting grille 603 seals the water inlet of the tunnel, and the intercepting grille 603 is inclined forward from bottom to top.

[0032] A plurality of ground nails 8 extending in the vertical direction are fixedly connected to the bottom of the mounting frame 601. After the concrete pouring layer 4 is laid, the mounting frame 601 is inserted into the concrete pouring layer 4 through the ground nails 8. After the concrete pouring layer 4 reaches the specified strength, the ground nails 8 are fixedly installed in the concrete pouring layer 4.

[0033] A locking member is provided on the rotating frame 602. The locking member includes a locking frame 604. The locking frame 604 is fixedly connected to the rear side of the rotating frame 602. A through hole penetrating left and right is formed in the locking frame 604. A threaded structure adapted to the locking screw 605 is provided in the through hole. The locking screw 605 is threadedly connected in the through hole. An insertion hole adjacent to the locking frame 604 is formed in the support arch top. One end of the locking screw 605 away from the locking frame 604 is inserted into the insertion hole.

[0034] A sedimentation tank 7 with an upper opening is provided on the tunnel foundation soil layer 1. The top of the sedimentation tank 7 is flush with the tunnel foundation soil layer 1, and the sedimentation tank 7 is located below the front side of the interceptor 6. A filter screen 702 is also included. A plurality of hooks 701 are provided on the inner wall of the sedimentation tank 7. A plurality of hanging buckles are provided on the filter screen 702. The hanging buckles are hooked and connected with the corresponding hooks 701.

[0035] A valve 9 is provided in the tunnel. The valve 9 fills the gap between the arch-shaped supports 2. An inlet valve 901 is provided on the valve 9.

[0036] Working principle: When flood drainage is required, the inlet valve 901 on the valve 9 is opened. Water flows through the gaps on the intercepting grille 603 and into the tunnel, while debris such as gravel and branches in the water is intercepted by the intercepting grille 603.

[0037] After the water flow disappears, since the intercepting grille 603 is inclined from bottom to top, under the action of gravity, debris such as gravel and branches falls into the sedimentation tank 7. Then, construction workers use a water pump or other pumping devices to pump the water flow in the sedimentation tank 7 away. The debris falls into the filter screen 702 of the sedimentation tank 7. By removing the filter screen 702, the debris can be quickly packed and collected, which is convenient for processing the debris.

[0038] When personnel need to enter the culvert for maintenance, rotate the locking screw rod 605 to disengage it from the socket, so that the interception grille 603 is unlocked. Then pull the interception grille 603, and the interception grille 603 drives the rotating frame 602 to rotate around the hinge point with the mounting frame 601, so as to lay the interception grille 603 flat. Then the construction personnel lay a cover plate on the sedimentation tank 7 to facilitate the passage of personnel and the transportation of materials.

[0039] Thus, sundries in the water flow can be quickly filtered, and the sundries fall into the sedimentation tank and are uniformly collected through the filter screen, which is convenient for cleaning the sundries. At the same time, when the culvert is maintained, the interception grille (603) can be quickly laid flat, which is convenient for material transportation and personnel entry.

[0040] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
