The utility model discloses a flexible topological diversion wall for live water in a broken river, which comprises a positioning pile, a flexible anti-seepage membrane, a float and a sink; the sink and the float are connected in channeling shape respectively, the sink is fixed or sleeved at the lower part of the positioning pile, the float is sleeved at the upper part of the positioning pile, and the sink is fixed at the bottom of the flexible anti-seepage membrane. The float is fixed on the top of the flexible impervious membrane to form a flexible wall. When in use, one end of the wall is located about 1/2 of the width of the broken end river, and the other end is connected with the bank wall on the other side of the main river; the height of the wall is higher than the highest water level of the river. The wall changes the topological relationship between the main channel and the broken-end River on its side, so that the flow of water flows on the topological structure of a through line, and plays a role in guiding the flow of the broken-end river. The utility model adopts a flexible structure wall, which has the advantages of convenient implementation, good effect of connecting live water, low project investment, short construction period and low operation and maintenance cost.

一种用于断头河活水的柔性拓扑导流墙
本技术涉及一种用于断头河活水的柔性拓扑导流墙,特别适用于城市建成区的断头河连通活水。
技术介绍
城市河道水环境治理任务十分繁重,连通断头河实现畅流活水是其中一项极为重要的治理措施。在本技术作出之前,公开号为CN205804274U的中国技术专利提供了一种用于主河道一侧断头河水连通的拓扑导流墙,与传统的断头河连通方法相比(开河连通、管道连通、泵站注水),该专利技术提供的技术方案大幅度地提高了活水效果及节省了投资成本。然而,技术方案涉及的墙体形式分别是钢筋混凝土直立墙以及拉森板桩连续墙,该类墙体在施工程序上相对较复杂。此外,由于这类刚性墙体具有一定的截面厚度,因此将会减小河道的过水断面,从而对过水能力有所影响。
技术实现思路
本技术针对现有连通断头河的导流墙存在的不足,提供一种活水效果好,施工简便,成本节约的柔性拓扑导流墙。实现本技术目的的技术方案是提供一种用于断头河活水的柔性拓扑导流墙,它包括定位桩、柔性防渗膜、浮子和沉子;沉子和浮子分别连成窜状,沉子固定或窜套接于定位桩的下部,浮子窜套接于定位桩的上部;沉子固定于柔性防渗膜的底部,浮子固定于柔性防渗膜的顶部,形成柔性墙体。本技术技术方案中,所述的柔性防渗膜为土工布,其高度大于河道的最大水深10~20cm;所述浮子为轻质泡沫材料;所述沉子为铁块或石块。安装柔性拓扑导流墙时,在河面宽为B的断头河宽度的中心位置处,设置一道墙体,墙体的一端始于离断头河尽头B/2处,另一端与主河道另一侧边的岸墙连接。通过设置一道拓扑导流墙,把一条主河道和一条断头河原来4点3线的拓扑结构改成了2点1线的 ...
