Draining device for internal soft silt layer of silt storage yard or fill area

Abstract

The invention discloses a draining device for an internal soft silt layer of a silt storage yard or a fill area. The draining device comprises a cylindrical draining body pressed in silt; the cylindrical draining body comprises a frame; a plastic blind ditch is plugged in a cylindrical part of the frame; a tooth-shaped sleeve is fixedly connected on one end part of the cylindrical part of the frame; a piece of filter cloth is wrapped on other cylindrical parts of the frame and fixedly connected with the tooth-shaped sleeve; a sealing end plate is respectively arranged on each of the two ends of the frame; the draining body is rotationally connected on two hard vacuum tubes via the sealing end plates on two ends of the draining body; the two hard vacuum tubes are also located on two ends of the draining body; an intake port of the hard vacuum tube is located in a hollow structure of the draining body while an exhaust port of the hard vacuum tube is connected with an external vacuum air extractor; the tooth-shaped sleeve is connected with an external motor via a transmission belt; and a hair brush is arranged on the draining body where the filter cloth is wrapped. The draining device disclosed by the invention can ensure high efficiency of the draining body and has the advantages of a simple structure, light weight, simple and convenient operation and high efficiency.

Description

technical field [0001] The invention relates to a silt drainage device, in particular to a drainage device for thin and soft silt layers inside a silt stockyard and a dredging reclamation site. Background technique [0002] In river dredging and dredging projects and sea reclamation projects, the problem of dredging and filling consolidation of soil with high water content will be encountered. For a site filled with high water content silt, if the drainage of the site is not smooth or the clay content of the dredged fill soil is high, the consolidation and settlement will be a long process. During this long process, after a long period of wind, sun and surface evaporation, a thick hard shell layer will be formed on the surface of the dredged fill soil layer, mixed with the rhizome residues of herbaceous plants, making the topsoil have a certain surface However, most engineering monitoring results show that the soil still maintains a high water content at a certain depth und...

AI Technical Summary

Problems solved by technology

Among the current drainage measures, the efficiency of vacuum pumping is the highest, but after a period of vacuum pumping in the soft, high-moisture silt yard, there will be a thick layer of wrapped mud around the drainage body, which hinders the drainage body and Contact with external silt, which reduces the rate of drainage
