Scraping plate type anti-silting drainage device and drainage method thereof

Abstract

The invention relates to a scraping plate type anti-silting drainage device. The scraping plate type anti-silting drainage device comprises a hard vacuum pipeline support, a rotary cylinder drainage body and a spring scraping plate, wherein the two end surfaces of the rotary cylinder drainage body are connected with the hard vacuum pipeline support, connecting points are of the rotation centers of the rotary cylinder drainage body, and the two end surfaces of the rotary cylinder drainage body are sealed; and the spring scraping plate is connected with the hard vacuum pipeline support and in contact with the rotary cylinder drainage body by a certain angle, the length of the spring scraping plate is matched with that of the rotary cylinder drainage body, and a row of scraping heads are arranged at one end of the spring scraping plate, which is in contact with the rotary cylinder drainage body. The scraping plate type anti-silting drainage device disclosed by the invention can effectively solve the shortcoming that the drainage efficiency is reduced because the drainage body is easy to cause silting by a mud layer and ensure high-efficient drainage; and furthermore, the scraping plate type anti-silting drainage device has the advantages of simple and light-weight structure, simplicity and convenience in operation and good reliability.

Description

technical field [0001] The present invention relates to an anti-silting vacuum drainage device and its method, more specifically to a scraper-type silt accumulation and drainage device and its method applied to silt yards and dredging fields. Background technique [0002] In river dredging and dredging projects and land reclamation projects, the problem of dredging and 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 content of clay in the dredged soil is high, the natural 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 maint...

AI Technical Summary

Problems solved by technology

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