River bed load sediment blocking structure for water diversion facility and construction method of river bed load sediment blocking structure
The invention discloses a river bed load sediment blocking structure for a water diversion facility and a construction method of the river bed load sediment blocking structure, and belongs to the technical field of water conservancy and hydropower engineering building design and construction. The silt blocking structure comprises an upstream silt blocking pier, a silt settling ditch and a downstream silt blocking pier. The upstream sand blocking piers and the downstream sand blocking piers are used for reducing the movement speed of part of bed load sediment and even stopping the movement of the part of bed load sediment, the sediment is intercepted and stored through the desilting ditches, the sediment in the desilting ditches is regularly cleaned in a mechanical mode, and finally the purpose of reducing sediment deposition near a water diversion facility is achieved. The invention further discloses a construction method of the structure. The sand blocking piers can be constructed by using steel barrel piles, and the sand sedimentation ditches can be directly excavated by a grab dredger. In addition, the structure is simple, construction is easy and convenient, and good application prospects are achieved.
本发明公开了一种用于引水设施的河道推移质泥沙阻拦结构及其施工方法，属于水利水电工程建筑物设计建造技术领域。所述的泥沙阻拦结构包括上游挡沙墩、沉沙沟和下游挡沙墩。本发明利用上游挡沙墩和下游挡沙墩，降低部分推移质泥沙的运动速度甚至使其停止运动，利用沉沙沟拦截、存储泥沙，使用机械方式定期清理沉沙沟内泥沙，最终达到减少引水设施附近泥沙淤积的目的。本发明还公开了上述结构的施工方法。所述挡沙墩可利用钢桶桩建设，所述沉沙沟可由抓斗式挖泥船直接挖掘形成。此外，本发明结构形式简单，施工简单便捷，具有良好的应用前景。
