Description
Technical Field
The utility model relates to a repeatedly usable's dehydration geotechnological tube bag belongs to hydraulic engineering and dredges technical field.
Background
To the inventors' knowledge, a geotextile tube is a bag-like material made of geotextile. The solid-liquid mixture is filled in the geotextile, water permeates out of the pipe bag by utilizing the water permeability of the geotextile, and solid particles are remained in the pipe bag. The application of the geotextile tube bag technology mainly comprises two aspects, namely a geotextile tube bag cofferdam technology, namely a cofferdam or a dam with certain strength and stability is built by taking sand or dredged sludge as a filling material and carrying out layered water filtration or dehydration solidification according to a set section shape; the other is a geotechnical pipe bag dehydration technology, which aims at solid-liquid separation, fills conditioned sludge slurry into a pipe bag, allows water to seep out of the pipe bag, retains the sludge in the pipe bag, and treats the sludge (residual soil) after the sludge is dehydrated to reach a certain water content, such as application in the fields of municipal and industrial sludge, sludge in farming, fishery farms, dredging bottom mud in rivers and lakes, and the like.
For the dehydration technology of the geotechnical pipe bag, the working procedures are mainly divided into the steps of pipe bag manufacturing, slurry conditioning, slurry filling, dehydration and drying, soil taking and disposal and the like. The prior art is mainly realized in the following three ways: the first is a natural dehydration mode of the geotechnical pipe bag, slurry conditioning is carried out without adding a medicament, and the sludge is dehydrated through filling pressure, self-weight dehydration and natural evaporation, air drying and dehydration, so as to meet the sludge dehydration requirement; the second is a flocculation dehydration mode of the geotechnical pipe bag, namely, a flocculating agent is added after the mud is conditioned, and the flocculated mud is filled into the pipe bag, so that the mud and the water are quickly separated, and the dehydration efficiency is greatly improved; and the third mode is a vacuum dehydration mode of the soil engineering pipe bags, namely, on the basis of the two dehydration modes of the soil engineering pipe bags, a vacuum drainage system is additionally arranged, a vacuum pumping system is started after filling pressure dehydration is finished, vacuum negative pressure is formed in the soil body of the pipe bags to force drainage, and sludge dehydration and solidification are accelerated.
The main disadvantages of the three geotube bag dehydration modes are that: (1) under the existing construction conditions, the operation mode of bag-opening and soil-taking is limited after dehydration is finished, the pipe bag is mostly disposable, soil-taking usually damages the bag body, the bag body is discarded as waste, the construction cost is increased, and the environment is polluted. (2) Because the pipe bag is disposable, because of use cost consideration, the user often is difficult to select for use high strength, high permeability's novel geotextile, has restricted the progress of geotechnological pipe bag dewatering technology to a certain extent. (3) The traditional earthwork tube bag is manufactured by wrapping or overlapping earthwork fabrics, sewing the edges of the earthwork fabrics in a sewing way to form a bag body, and arranging a filling port at the upper part of the bag body. In the pressure filling process, the bag body is pressed and expanded, stress concentration is formed at the position of a sewing line, and sometimes, the edge of the sewing line is expanded or the bag body at the position of the sewing line is pulled to crack, so that slurry leakage is caused, and the using function of the tube bag is lost or reduced.
