Example Embodiment

[0030] Hereinafter, the present invention will be further described with reference to the drawings and specific implementations. It should be noted that, provided that there is no conflict, the following embodiments or technical features can be combined to form new embodiments. .

[0031] An anti-flood dam with a mud-water separation device can remove the mud and sand accumulated at the bottom of the dam, and at the same time separate the mud and water, so as to facilitate subsequent collection and transportation of the mud and sand for treatment.

[0032] Such as figure 1 As shown, the flood prevention dam includes a bottom surface 2 and a water facing surface 1. The bottom surface 2 is the bottom of the river course. The bottom surface 2 of the dam can be set to be horizontal or inclined toward the water facing surface 1. The structure, that is, the side close to the waterfront surface 1 is relatively low, and the side far away from the waterfront surface 1 is relatively high, so...

Abstract

The invention discloses a flood control dam with a mud-water separation device. The flood control dam comprises a dam body, a mud guiding device, a stirring pool and the mud-water separation device. The dam body comprises a bottom face and an upstream face. A dam opening is formed in the included angle position between the bottom face and the upstream face. The mud guiding device comprises a drivedevice and a water intercepting valve connected with the drive device. The water intercepting valve is located at the dam opening and shields the dam opening when the water intercepting valve is closed. The stirring pool communicates with the dam opening and is connected with the mud-water separation device through a pipeline provided with a water pump. The mud-water separation device comprises an inner wall arranged to be of a hollow inverted-cone-shaped structure. A feeding port of the mud-water separation device is located in the top of the inner wall, and the water outlet direction of thefeeding port is tangent to the cross section of the mud-water separation device where the feeding port is located. A plurality of meshes are formed in the inner wall, mud water sprayed out of the feeding port spirally flows downwards along the inner wall, the mud water is made to do centrifugal motion, water in the mud water is thrown out of the meshes, and sediment accumulated at the bottom of the dam is collected.

Description

technical field [0001] The invention relates to the field of small flood control dams, in particular to a flood control dam with a mud-water separation device. Background technique [0002] A dam is a water-retaining structure that intercepts the water flow of a river channel to raise the water level or regulate the flow. However, the existing dams all have an inclined water-facing surface, that is, there is a certain angle between the water-facing surface and the river ground. When the river water hits the dam, the water-facing surface can intercept the river flow while buffering part of the potential energy of the water flow, preventing the river from Across the dam, thus having the effect of flood control. [0003] However, when the river water flows to the upstream side of the dam, the flow of the river will carry some sediment and wash it to the upstream side of the dam. When the dam is closed, the fluidity of the water is poor, making the sediment easy to accumulate o...
