Sediment storage dam structure of counterfort type front desilting basin
The invention discloses a sediment storage dam structure of a counterfort type front desilting basin, and belongs to the technical field of water conservancy and hydropower engineering. The structure comprises a desilting basin and a sediment storage dam, the sediment storage dam is arranged on the downstream of the desilting basin, the sediment storage dam comprises a dam body and a front heel plate, and the front heel plate is arranged on the upstream face of the dam body. The weight of silt deposited on the front heel slab and the weight of water right above the front heel slab can be fully utilized, the section of the dam body is reduced on the basis of ensuring the stability of the dam body, and meanwhile, the sand settling basin is arranged in front, so that the flow velocity of water flow is reduced, the silt is settled in the basin, and the sand settling effect is improved. The invention provides a method for calculating the anti-sliding stability safety coefficient K of the sediment storage dam along the dam foundation surface and the anchoring force M of the joint bars to the sediment storage dam, and the anti-sliding stability and safety of the sediment storage dam are guaranteed.
本发明公开了一种扶壁式前置沉沙池的拦沙坝结构，属于水利水电工程技术领域。该结构包括沉沙池和拦沙坝，所述拦沙坝设在沉沙池的下游，所述拦沙坝包括坝体和前踵板，所述前踵板设在坝体的迎水面上。能充分利用沉积在前踵板上的泥沙重量，及前踵板正上方水的重量，在保证坝体稳定的基础上减小了坝体断面，同时前置沉沙池，以减小水流流速，将泥沙沉淀于池中，提高了沉沙效果。提供了拦沙坝沿坝基面的抗滑稳定安全系数K和插筋对拦沙坝锚固力M的计算方法，保证了拦沙坝的抗滑稳定性和安全性。
