Geotextile tube with inner cores and mud dehydration method combining geotextile tube with vacuum

Abstract

The invention discloses a geotextile tube with inner cores and a mud dehydration method combining the geotextile tube with vacuum. The geotextile tube comprises bottom cloth, top cloth, a plurality ofgeotextile inner cores, filtering tubes and sand, wherein the top cloth is in a shape of a polygon; a filling connector is arranged on the top cloth; the size and the shape of the bottom cloth are identical to those of the top cloth; the bottom cloth and the top cloth are overlapped together to form the sealed geotextile tube through sewing; the geotextile inner cores are arranged between the topcloth and the bottom cloth; the filtering tubes are round tubes with water drainage holes in the circumferences; and the geotextile inner cores are filled with sand or the filtering tubes are inserted into the geotextile inner cores to form internal water drainage channels. The geotextile tube combines circumferential water drainage, inner core water drainage and vacuum dehydration, thus water drainage ways and water drainage pressure differences can be increased, the water drainage distance can be reduced, the mud dehydration efficiency can be effectively improved, and the phenomenon of "wetmud core" of a conventional geotextile tube in dehydration can be avoided.

Description

technical field [0001] The invention relates to a geotechnical pipe bag in a geotextile fabric and a method for dehydrating mud in combination with vacuum, in particular to a geotechnical pipe bag with an inner core and a method for treating mud in combination with vacuum dehydration. Background technique [0002] In recent years, my country's infrastructure construction and environmental improvement projects have developed rapidly. A large amount of silt or mud will be produced in river channel dredging, ditch dredging, pile foundation hole excavation and other projects. These silt and mud are suspended liquids containing a certain amount of fine soil particles, have a certain viscosity, and need to stand for a long time before they can be deposited in layers. At present, the mud treatment methods mainly include the sedimentation and air-drying method in the mud pool, the method of transporting the tank truck to the designated place for stacking, and the mechanical pressin...

Problems solved by technology

However, in the process of actually using the geotechnical tube bag, the dehydration effect of the geotechnical tube bag will become worse and worse, so that there will be a certain amount (depending on the capacity of the geotechnical tube bag) inside the geotechnical tube bag with high moisture content and flowing state. Mud, the phenomenon of "sugar heart" appears, this part of the mud is difficult to dehydrate and solidify
