Environment-friendly filling cofferdam system for river regulation and construction method
The invention relates to an environment-friendly filling cofferdam system for river regulation and a construction method. The environment-friendly filling cofferdam system comprises a cofferdam body, the cofferdam body is of a trapezoidal structure and is formed by stacking a plurality of sand bags in a staggered mode, each sand bag comprises a coating layer and a filler, and the coating layers are filled with the fillers. According to the method, a plurality of woven bags are filled with river sand, the cofferdam body is formed in a staggered stacking mode, the woven bags have certain strength and good water filtering performance, after the process of flushing and filling and water filtering at the same time for a period of time, water in slurry in the sand bags and part of clayey soil are discharged from pores in the surface of the woven bag cloth under the action of pump pressure and self-gravity, and most of the soil particles are deposited under the action of self-gravity to gradually form a sandbag cofferdam body. According to the cofferdam system, the construction procedure is fast, the investment of constructors is small, the filling sand is easy to obtain and can be recycled, no pollution is generated to the natural ecology of a river channel during construction and dismantling, and secondary pollution to the river channel is avoided.
本发明涉及一种河道治理环保冲填围堰体系及施工方法，包括堰体，所述堰体为梯形结构且由若干砂袋交错堆积而成，所述砂袋包括包覆层和填充物，所述包覆层内填充有填充物。本发明方法由若干编织袋内填充河沙，并通过交错码放的方式形成堰体，编织袋具有一定的强度和较好的滤水性能,经过一段时间的边冲填边滤水过程后,沙袋内泥浆中的水和部分粉黏粒土在泵压力及自重力作用下,从编织袋布料表面孔隙中排出,而大部分土颗粒在自重力作用下沉积下来,逐渐形成沙袋堰体。本发明围堰体系施工工序快捷、施工人员投入少、冲填砂易获取并可重复利用、施工和拆除时不会对河道自然生态产生任何污染，避免了对河道的二次污染。
