Method for treating foundation through stirring flocculation dehydration and vacuum preloading jointly
The invention discloses a method for treating a foundation through stirring flocculation dehydration and vacuum preloading jointly. The method is characterized by including the following steps that A, an automatic stirring device is gradually driven to a target region, in the driving process of the automatic stirring device, a stirring rod of the automatic stirring device extends deeply into sludge and stirs the sludge continuously, the stirring rod injects a flocculating agent into the sludge in the stirring process, and a vertical drainage board is then inserted in the sludge into which the flocculating agent is injected; B, the upper end of the vertical drainage board is connected with a drainage pipeline, the drainage pipeline is connected with the external environment, the top of sludge in a vacuum preloading water pond and the drainage pipeline are covered with sealing cloth, the edges of the sealing cloth are sealed with the sludge through sealing structures, and a vacuum pump is connected with the drainage pipeline and pumps water in the sludge; C, after vacuum preloading is finished, the vacuum sealing cloth on the surface is removed, and the drainage pipeline and the vertical drainage board are detached. By the adoption of the method for treating the foundation, the vertical drainage board can be prevented from being blocked through tiny soil particles and drainage efficiency can be improved.
