Construction method for rapidly heightening water retaining sub-weir of cofferdam
According to the construction method, flexible dam bags are arranged on a cofferdam body to serve as the heightened water retaining sub-weir, the dam bags and the cofferdam body are anchored, the dam bags are filled with water according to the requirements of actual working conditions such as the river water level and the upstream incoming water flow, the water filling amount is controlled in real time, and the water retaining sub-weir can be rapidly heightened. And the dam bag quickly forms a heightened water retaining sub-weir with a corresponding height. The heightened water retaining sub-weir is rapid in construction and development, high in overall structural strength, reliable in operation and low in overall manufacturing cost, effectively solves the technical problems that an existing heightened sub-weir is low in structural strength and reliability, quick in construction, relatively long in construction period, high in manufacturing cost and the like, and has good application prospects in the technical field of water conservancy cofferdam engineering.
本发明公开一种围堰快速加高挡水子堰施工方法，本发明采用在围堰体上布设柔性的坝袋作为加高挡水子堰，坝袋与围堰体进行锚固，根据河道水位及上游来水流量等实际工况的需求，对坝袋进行充水，通过实时控制充水量，坝袋快速形成相应高度的加高挡水子堰。本发明的加高挡水子堰施工展开快速、整体结构强度高、运行可靠、整体造价低，有效解决了现有加高子堰结构强度低、可靠性低、施工仓促、建设周期相对较长、造价高等技术问题，在水利围堰工程技术领域具有很好的应用前景。
