Water conservancy project flood discharge anti-seepage dam

Abstract

The invention discloses a water conservancy project flood discharge anti-seepage dam. The dam comprises a dam body and a dam body base, the dam body base is arranged on a foundation, the dam body is arranged on the dam body base, one side of the dam body is a water storage area, one side, close to the water storage area, of the dam body is sequentially provided with a masonry stone layer, a brickmasonry layer and a concrete layer from inside to outside, and one side, far away from the water storage area, of the dam body is sequentially provided a first reinforced layer and a second reinforcedlayer from inside to outside, a flood discharge channel is arranged between the top of the dam body base and the dam body, guide grooves are symmetrically formed in the dam body and the dam body base, a water gate for cutting off the flood discharge channel is installed between the two guide grooves, the water gate comprises a pull rod, a unit plate and an installation frame, two ends of the installation frame are respectively arranged in the two guide grooves, and the installation frame is a rectangular frame. According to the dam, the dam body is stable in structure, the water gate is switched on and off slowly, water flow cannot be suddenly increased or reduced during flood discharge, and the dam body is effectively protected.

Description

technical field [0001] The invention relates to the field of water conservancy projects, in particular to flood discharge and seepage prevention dams of water conservancy projects. Background technique [0002] At present, water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. Also known as water engineering. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, canals, rafts, and fishways to achieve their goals.

Problems solved by technology

[0005] Traditional dams are mostly earth-rock dams or concrete dams. Due to the long-term erosion of the dam body by flowing water, erosion or concrete aging, etc., the pressure will be too high and the seepage volume will be large, which will cause the dam body to deform, and more seriously lead to accidents.

Moreover, after long-term use, the left and right dams will deviate due to water erosion and geological changes.

[0006] Some existing dams have simple structures, poor anti-seepage and anti-corrosion performance, and the sluice in the dam flood discharge channel is an integral structure. Decreased safety of the dam
