Ecological spur dike with adjustable permeable rate and working method thereof
The invention relates to an ecological spur dike with an adjustable permeable rate and a working method thereof. The ecological spur dike comprises a dike body, one side of the dike body is fixedly connected to a river bank, a lower portion of the dike body is fixedly connected to a riverbed, the dike body is perpendicular to the river bank and the riverbed, the dike body comprises a rectangular frame body, and a shutter gate with an adjustable opening degree is arranged in a middle part of the rectangular frame body; and ecological net cages are arranged on an upstream side and a downstream side of the dike body, and filter screens are arranged between the ecological net cages and the dike body. The provided ecological spur dike with an adjustable permeable rate has a reasonable design and a simple structure, is convenient to construct and easy to maintain, has low manufacturing cost, and can adapt to changes of water flows in flood periods and dry periods of most rivers by controlling the opening degree of the shutter gate of the dike body; and the ecological net cages are arranged, an eutrophication degree of a water body can be reduced, biodiversity of a riverway is protected, an aesthetic feeling of the riverway is increased, and requirements of most riverways for water level control and ecology protection are met.
本发明涉及一种可调节透水率的生态丁坝及其工作方法，包括一侧固定连接于河岸、下部固定连接于河床的坝体，所述坝体垂直于河岸同时也垂直于河床，所述坝体包括矩形框体，所述矩形框体中间安装有开度可调的百叶闸门；坝体的上游侧和下游侧均设有生态网箱，所述生态网箱与坝体之间设有过滤网。本发明提供的可调节透水率的生态丁坝设计合理，结构简单、施工方便、易于维护、造价较低，通过控制坝体百叶闸门的开度，可以适应大多数河道洪水期与枯水期水流的变化；通过配置生态网箱，可以降低水体富营养化程度并保护河道生物多样性，增加河道的美感，满足多数河道控制水位、保护生态的要求。
