Reservoir silt reduction structure combining sand retaining dam and diving ditch
The invention discloses a reservoir silt reduction structure combining a sand retaining dam and a diving ditch. The top of the diving ditch is a detachable top plate, and the top of the top plate is a circular hole. And the diving ditch is connected with the sand retaining dam through a rectification drainage channel. The sand retaining dam is of a trapezoidal dam body structure, and a circular hole is formed in the dam top. When water flows through the structure, the water flows into the diving ditch through the holes in the top plate at the top of the diving ditch and then flows into the sand retaining dam through the middle rectifying holes. Due to the trapezoidal structure of the dam body of the sand retaining dam, water flow can generate a turbulent flow field in the dam body, sediment accumulation in the dam body is accelerated, and a part of the dam body structure is formed. And finally, the water flow with low silt content flows out from an overflow hole in the top of the sand retaining dam. The top plate of the diving ditch is detachable, and follow-up centralized desilting is facilitated. The dam body structure of the sand retaining dam forms turbulent water flow, sediment is promoted to deposit in the dam body to form a part of the dam body, and the construction cost is reduced.
本发明公开了一种挡沙坝和潜水沟结合的水库减淤结构。潜水沟位于挡沙坝上游，潜水沟顶部为拆卸的顶板，顶板顶部为圆形孔洞。潜水沟与挡沙坝之间通过整流排水通道相连。所述挡沙坝为梯形坝身结构，坝顶开设圆形状孔洞。当水流经过结构时，将通过潜水沟顶部顶板的孔洞流入潜水沟，然后通过中间整流孔流入挡沙坝内部。由于挡沙坝坝身的梯形结构，水流会在坝体内部产生紊流流场，加速泥沙在坝身内部淤积，形成坝身结构的一部分。最后泥沙含量较低的水流从挡沙坝顶部的溢流孔流出。潜水沟的顶板可拆卸，方便后续集中清淤。挡沙坝坝身结构形成紊动水流，促进泥沙在坝体内部淤积，形成坝身一部分，降低建造成本。
