Embodiment Construction

[0014] A rockfill dam structure, comprising a dam main body 1 and a water channel main body 2, the bottom of the dam main body 1 is provided with a drainage pipe 3, and the drainage pipe 3 extends to the water channel main body 2, and the water channel main body 2 is provided with On the spillway 4.

[0015] In the aforementioned rockfill dam structure, the upstream water inlet 6 and the downstream water outlet 7 of the drainage pipe are provided with rotating cover plates 8 at intervals.

[0016] In the aforementioned rockfill dam structure, the dam protection slope 5 of the main body of the dam is provided with grid-shaped water channels.

[0017] During specific implementation, start from the dam foundation along the upstream direction to tamp the foundation for constructing drainage pipes to the upstream water inlet, make the foundation tilt toward the downstream water outlet during tamping, and then pour reinforced concrete on the rammed foundation along the foundation su...

Abstract

The invention relates to dams at the foot of the hill, in particular to a rockfill dam structure. The rockfill dam structure comprises a dam body and a water channel body. A water drainage pipeline is arranged at the bottom of the dam body and extends to the water channel body all the time. The water channel body is provided with flood discharge ports located in the different horizontal planes. Rotating cover plates arranged at intervals are arranged at an upstream water inlet and a downstream water outlet of the drainage pipeline. A grid-shaped trench is arranged on the dam protection slope surface of the dam body. The rockfill dam structure is provided. The drainage pipeline in the structure is arranged at the rear portion of the dam body, in terms of environmental protection, the staying time of water in the dam body is prolonged, and the precipitation capacity of soil is increased. The impact force to the dam body from water is greatly reduced, and the dam body is protected accordingly. The water channel body is provided with the flood discharge ports, and when the rainfall is large, water in the dam body can be drained in time.

Description

technical field [0001] The invention relates to a dam at the foot of a mountain, in particular to a rockfill dam structure. Background technique [0002] The main body of the rockfill dam is a dam that is filled with stone materials and equipped with anti-seepage bodies. It is a kind of earth-rock dam. The advantages of this kind of dam are that it can make full use of local natural materials, can adapt to different geological conditions, the construction method is relatively simple, and its anti-seismic performance is good. The rockfill dam at the foot of the mountain mainly plays the role of preventing water and soil loss. The upstream of the rockfill dam is also equipped with a waterway main body. The drainage pipes of the traditional rockfill dam are built in front of the rockfill dam. Look, the impact force of the flood on the stone dam cannot be reduced, especially during the flood period, the water flow in the stone dam is almost towards the main body of the stone d...
