七格下坝下游段合金网兜抛石施工

Construction of Alloy Net Riprap in Downstream Section of Qige Dam

合金网兜抛石支护能克服传统的单体块石、草包、编织袋等护岸固脚方法易被冲走、抗冲性能稳定差等不足,逐渐成为水利工程堤防建设和围海工程围堤建设最常使用的护岸固脚施工措施.钱塘江七格下坝下游段涌潮区使用合金网兜抛石护岸固脚施工技术方案,不仅为堤坝的稳定固脚起到了积极的作用,同时有利于涌潮区域开展施工作业以及开展海塘零星抢险机械化,是当前经济高效的堤塘稳定固脚方案.

The alloy net riprap support is used to overcome the technical shortcomings of revetment method by the traditional single stones, straw bags, and woven bags, which are easy to be flushed out with poor impact resistance. The new technolo-gy gradually becomes the most used approaches in bank protection and dike firming of levee construction in water conservan-cy projects and causeway construction in reclamation engineering. The technique scheme of revetment by alloy net riprap is analyzed in this paper based on the living example in Qige downstream tidal area of Qiantang River, with positive impact on dam stability and sporadic rescue , which proves to be cost effective in revetment construction.
