Flocculating agent injecting and adding device for internal soft silt layer of silt storage yard or fill area

Abstract

The invention discloses a flocculating agent injecting and adding device for an internal soft silt layer of a silt storage yard or a fill area. The flocculating agent injecting and adding device comprises a motor, a stirring rod, a stirring head and a flocculating agent filling sleeve; the stirring rod is driven by the motor; the stirring head comprises a stirring shaft fixedly connected with a lower end of the stirring rod; a plurality of layers of propeller blades are arranged on the stirring shaft; the flocculating agent filling sleeve is sleeved outside the stirring rod, and two ends of the flocculating agent filling sleeve are hermetically and rotationally connected with the stirring rod respectively via a sealing end plate; a plurality of through holes are arranged on a sleeve wall of the flocculating agent filling sleeve; and a flocculating agent filling soft tube is connected on the sealing end plate on an upper end of the flocculating agent filling sleeve. In the invention, a flocculating agent is injected while rotating and stirring silt so that the uniformity of injection and the use efficiency of the flocculating agent are improved. The flocculating agent injecting and adding device disclosed by the invention has the advantages of a simple structure, light weight, simple and convenient operation, high efficiency and good reliability.

Description

technical field [0001] The invention relates to a flocculant adding device, in particular to a flocculant injection adding device for a thin soft mud layer inside a sludge 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 a...

Problems solved by technology

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 underground, even in a semi-fluid state close to the initial state; although the surface soil has a certain strength and can be walked on , but it is difficult for some small drilling machinery to enter the site, let alone large machinery

For projects that are eager to use land for further engineering and land acquisition as soon as possible, how to quickly reduce the moisture content of high-moisture silt in the storage yard, improve the degree of consolidation, and increase the bearing capacity is the key issue, so artificial means are required To speed up the consolidation process, adding chemical flocculants is one of the commonly used methods, but how to uniformly add flocculants to the thin and soft sludge deep inside the stockyard is still an unsolved engineering problem
