Abstract

The invention discloses a horizontal drainage plate combined geotextile vacuum preloading method sludge treatment system. The horizontal drainage plate combined geotextile vacuum preloading method sludge treatment system comprises a mud pit, transverse drainage plates, geotextile, a pumping and draining pipeline and a vacuumizing device; the mud pit is filled with sludge; the transverse drainage plates are transversely distributed in mud in the mud pit layer by layer; geotextile is correspondingly arranged on each layer of the transverse drainage plates in an attached mode, the geotextile is formed by needling or weaving synthetic fibers; vertical main pipes are vertically arranged at the positions, close to the two opposite side walls of the mud pit, in the mud pit, and the vertical mainpipes are connected with the transverse drainage plates through transverse branch pipes. The invention further provides a construction method of the system. The horizontal drainage plate combined geotextile vacuum preloading method sludge treatment system and the construction method are higher in drainage efficiency and wider in coverage range.

Description

technical field [0001] The invention relates to a system for treating sludge with a horizontal drainage board combined with a geotextile vacuum preloading method. The invention also relates to a construction method of the above-mentioned horizontal drainage board combined with geotextile vacuum preloading method for treating sludge. Background technique [0002] In traditional vacuum preloading, fine soil particles are easy to block in the pores of the filter membrane of the drainage plate, causing silting of the drainage plate, resulting in a decrease in drainage efficiency. Moreover, the degree of vacuum attenuates along the depth of the vertical drainage plate, resulting in poor treatment effect of traditional vacuum preloading on the underlying soil. [0003] Geotextile is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. In traditional vacuum preloading, geotextiles are often laid on the surface of the silt to prevent punct...
