Pipeline dredging method for trenchless large underground pipe network
The invention discloses a trenchless large underground pipe network pipeline desilting method, and relates to the technical field of trenchless underground pipeline desilting, in the spiral wriggling process of sludge in a spiral extrusion device, the inner diameter of the spiral extrusion device is gradually reduced from the feed port end to the discharge port end, and water in the sludge is gradually extruded out when the sludge is extruded to move forwards; the discharging port end of the spiral extrusion device inclines towards the feeding port end, water flows out of the feeding port through inclination potential energy of the inner wall of the spiral extrusion device, the dehydrated silt is guided out of the discharging port, and mud-water separation aftertreatment is directly completed in the desilting process.
本发明公开一种非开挖大型地下管网管道清淤方法，涉及非开挖地下管道清淤技术领域，淤泥在螺旋挤压装置内螺旋蠕动过程中，螺旋挤压装置内径从进料口端起逐渐向出料口端缩小，淤泥被挤压前行中逐渐挤出淤泥中的水；螺旋挤压装置出料口端向进料口端倾斜，水经螺旋挤压装置内壁的倾斜势能从进料口流出，脱水后的泥沙从出料口导出，清淤过程中同时直接完成泥水分离后处理。
