Ecological dredging device and method for sludge at bottoms of rivers, lakes and reservoirs
The invention provides an ecological dredging device and method for sludge at the bottoms of rivers, lakes and reservoirs, and relates to the technical field of dredging engineering.The device comprises a cover body, the bottom of the cover body is concaved inwards to form a cavity, an opening communicated with the cavity is formed in the top of the cover body, and the bottom of the cover body is used for being arranged on the interface of water and sludge; a stirring part of the twisting mechanism is arranged below the concave cavity; one end of the pipeline is connected with the opening, and the other end of the pipeline is placed at a set place; and the sludge suction assembly is arranged on the pipeline. Under the action of the cover body, slurry around the spiral reamer can be prevented from diffusing outwards, low-disturbance, anti-diffusion and high-concentration ecological dredging can be realized in river, lake and reservoir bottom sludge dredging engineering, and the spiral dredging device has the advantages that disturbance to water is small, dredging bottom sludge is not easy to diffuse, and dredging concentration is high.
本发明提供一种河湖库底部淤泥生态清淤装置及方法，涉及疏浚工程技术领域，该装置包括：罩体，罩体的底部向内侧凹陷形成有凹腔，罩体的顶部设有与凹腔连通的开口，罩体的底部用于设置在水和淤泥的界面上；绞动机构，绞动机构的搅拌部设置在凹腔的下方；管路，管路的一端与开口连接，管路的另一端放置在设定地点；吸泥组件，吸泥组件设置在管路上。在罩体的作用下可以防止螺旋绞刀周围的泥浆向外扩散，可以在河湖库底部淤泥清淤工程中，实现低扰动、防扩散、高浓度生态清淤，具有对水体扰动小，清淤底部淤泥不易扩散，挖泥浓度高的优点。
