Description

Anti-blocking automatic test device for vibrating geotextile tube bag

Technical Field

The utility model relates to a ground treatment research field, concretely relates to vibration geotechnique's pipe bag prevent stifled automatic test device.

Background

In the projects of river channel dredging, ditch and pond dredging and pile foundation hole excavation, a large amount of sludge or slurry is generated. These sludges and slurries often have the characteristics of high water content, large compressibility, strong fluidity and the like, and are difficult to meet the requirements of land transportation, recovery, reutilization and the like. The fluidity of the sludge after the dehydration treatment is reduced, and convenience can be provided for subsequent construction. The traditional slurry treatment methods, such as a slurry tank sedimentation air drying method, a tank outside vehicle transportation to a specified place stacking method, a mechanical squeezing method and the like, have the defects of high cost, low efficiency, easy leakage, pollution to the urban environment, potential safety hazard, post-land treatment and recovery and the like.

The geotextile tube bag method is developed on the background, overcomes the defects of the methods, has the advantages of low cost, high efficiency, quickness, convenience, environmental protection, large treatment capacity, easiness in operation and the like, and is widely applied to dehydration treatment of river and lake dredging sludge and municipal sludge.

However, the prior art still adopts a manual flapping method, and has the defects of uneven vibration, low efficiency, high labor consumption and the like.

The geotextile tube bag is used for treating a large amount of silt soil, so that the silt soil is drained and consolidated and has certain bearing capacity for foundation treatment and other geotechnical operations. However, when the conventional geotextile tube bag is used, because the soil particles contain more particles with small particle size and large specific surface area and sticky particles, sticky soil particle mortar is easily formed and adsorbed on the surface of geotextile and porous medium when water flows, a reverse filter layer appears in a drainage system, so that the permeability of the geotextile tube bag is poor, and the soil particles pass through the gaps of the coarse particles to move to the geotextile of the reverse filter layer in the water flow deposition and separation process, so that physical blockage is easily formed by deposition, and the number of effective seepage channels is reduced.

When the traditional geotube bag is used, the permeability of the geotube bag is deteriorated due to the formation of the reverse filter layer. The utility model discloses aim at slowing down the formation of reverse filter, the permeability of reinforcing geotechnological pipe bag shortens its water cycle, strengthens the work efficiency of arranging the system of oozing. Therefore, the method for deeply researching and slowing down the formation of the reverse filter layer has important guiding significance and reference value.
