Description

Technical Field

[0001] The utility model relates to the field of water conservancy facilities, in particular to a prefabricated culvert with a gate slot. Background Art

[0002] A culvert refers to a drainage channel (water passage) built under the roadbed and below the road surface during highway construction in order to allow the highway to pass through the canal smoothly without hindering traffic. This structure allows water to flow under the highway.

[0003] A Chinese utility model patent with publication number CN206538784U disclosed a prefabricated assembled box culvert on October 3, 2017, which includes a box culvert body in the shape of a cube, a socket and a spigot respectively located on both sides of the box culvert body, and a plurality of through holes arranged around the wall of the box culvert body along the laying direction of the prefabricated assembled box culvert. A connecting groove is provided in the central part of the inner wall of the box culvert body along the length direction, and the connecting groove is located on the through hole. The sockets and spigots on both sides of the box culvert are mainly used for connecting the box culverts with each other. Tight connection can achieve a good waterproof effect inside the box culvert. The connecting groove on the box culvert body can achieve further fixation between the mutually connected box culverts. The prefabricated assembled box culvert is easy to install and construct, has a large internal space, and can inspect and repair the pipeline without affecting the surrounding environment of the pipeline.

[0004] However, the above-mentioned publicly disclosed scheme has the following shortcomings: the existing box culvert does not have a gate slot adapted for the gate, so that the box culvert cannot be closed by the gate, and the flow rate and on-off of the water flow cannot be manually controlled. The subsequent installation of the gate and the hoist will damage the box culvert and affect the structural strength. Utility Model Content

A prefabricated culvert with a gate slot is provided.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model discloses a prefabricated culvert with a gate slot, comprising a box culvert, a gate culvert and a gate slot; a gate culvert is fixedly connected to the box culvert; a gate slot is provided in the gate culvert; a gate plate is slidably inserted in the gate slot; a weight-reducing slot is provided on the upper surface of the gate plate; an external cover plate is detachably fixedly connected to the upper end of the weight-reducing slot; a threaded shaft is inserted in the upper limit position of the external cover plate.

[0008] Furthermore, a plurality of central shafts are symmetrically fixed in the gate groove; a coil spring and a swing plate are rotatably sleeved on the central shaft; and an avoidance groove is provided on the gate plate corresponding to the swing plate.

[0009] Furthermore, a limiting groove is provided on the swing plate; the limiting groove is fixedly connected to one end of the coil spring; and the other end of the coil spring is fixedly connected to the central axis.

[0010] Furthermore, the swing plate is made of plastic.

[0011] The utility model provides a prefabricated culvert with a gate slot, which has the following beneficial effects:

[0012] 1. The utility model adds a gate culvert in the box culvert, a gate slot is opened in the gate culvert, a gate plate is slidably inserted in the gate slot, and the gate plate cooperates with an external cover plate and a threaded shaft, so that an external hoist can be connected to move up and down to adjust the flow rate of the water flow in the box culvert, solving the problem that the existing culvert does not have a slot for gate installation and the rear slot reduces the structural strength;

[0013] 2. The utility model has a coil spring and a swing plate sleeved on the central axis, so that the swing plate can rotate around the central axis and can be driven by flowing water to swing and clean the mud and debris in the gate groove, so that no accumulation will occur to affect the up and down movement and sealing of the gate plate, thereby solving the problem that mud and debris are easily accumulated in the existing gate groove to affect the switch and sealing.
