Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, in particular to an anti-seepage ecological protection structure for a dam of a water conservancy project. Background Art
[0002] The main reason why floods cause river embankments to be in danger or burst is that the scouring and pressure penetration of the embankments by the floods causes a large amount of water to seep into the embankments, thereby greatly reducing the embankments' ability to resist flood pressure. Under the continuous scouring and pressure penetration of the floods, the embankments will leak, pipe burst, and collapse. At present, the dangerous sections of the embankments are reinforced during flood prevention and control, mainly by using stones and sandbags to thicken and reinforce them.
[0003] After searching, the existing patent (publication number: CN212801421U) discloses an anti-seepage ecological protection structure for a water conservancy project dam to solve the technical problem that the lower end of the anti-seepage cloth in the prior art is not fixed and the anti-seepage effect on the dam body close to the bottom of the river is poor. The structure comprises a base, a dam, an anti-seepage cloth and a cloth pressing weight block. The base is connected to the riverbed, and the dam is constructed at the upper end of the base. A water-facing slope is formed on one side of the dam close to the riverbed, and a water-receiving slope is formed on the other side. The water-facing slope is paved with several anti-seepage cloths. A weight groove is formed on the upper end surface of the base close to the bottom of the water-facing slope. The upper end of the anti-seepage cloth bypasses the top of the dam and is fixed to the upper part of the water-receiving slope. The lower end of the anti-seepage cloth is laid in the weight groove. The cloth pressing weight block is located in the weight groove and presses the lower end of the anti-seepage cloth.
[0004] However, in the above scheme, the drainage performance of the waterproof dam is poor when in use, which easily leads to the accumulation of rainwater on the surface on rainy days. Moreover, when the dam is in use, the surface will be eroded by river water for a long time, and the surface will be slowly corroded.
[0005] In view of this, the utility model proposes an anti-seepage ecological protection structure for a water conservancy project dam. Utility Model Content
[0006] The utility model proposes an anti-seepage ecological protection structure for a water conservancy project dam, which solves the problem in the related art that the waterproof dam has poor drainage performance when in use, which easily leads to rainwater accumulation on the surface on rainy days, and the surface of the dam will be eroded by river water for a long time when in use, and the surface will be slowly corroded.
[0007] The technical solution of the utility model is as follows: an anti-seepage ecological protection structure for a water conservancy project dam, comprising a dam body, a guardrail fixedly connected to the top of the dam body, a drainage mechanism arranged on the surface of the dam body, the drainage mechanism comprising a protection component and a drainage component, the drainage component comprising a water discharge hole, a connecting hole and a drainage port, the water discharge hole being arranged at the top of the dam body, a connecting hole located inside the dam body being arranged below the water discharge hole, and the drainage port being arranged on both sides of the dam body and communicating with the connecting hole.

[0011] Preferably, the support plate, the baffle plate and the dam body form a triangular structure, and the baffle plate blocks the surface of the dam body.
[0012] The working principle and beneficial effects of the utility model are:
[0013] 1. In the utility model, by setting a baffle, when the water level rises, the water will continuously impact the surface of the dam body, and the baffle can well block the water flow to prevent the water flow from continuously impacting the dam body and causing the dam body to be corroded by the water flow. By setting the stairs, it is convenient for people to approach the river water for sampling or water level monitoring, without having to walk on the inclined surface of the dam body, and by setting the gravel layer, the gravel layer can prevent people from slipping when walking on the stairs.
