Embodiment Construction

[0007] The present invention adopts the geotextile with good water permeability as the bag cloth of the upper and lower layers of the filling bag, so that the water between the silt soft soil layer 1 and the drainage filter layer 2 is smooth, and the filling thickness of the silt soft soil filled with the woven geotextile bag is 50cm-100cm; Layer 2 is filled with woven geotextile bags or composite geotextile bags with fine and silt sand, or horizontal drainage boards are used to facilitate the rapid drainage of water in the soil. The woven geotextile bags or composite geotextile bags are filled with fine and silt sand with a thickness of 10-20cm Left and right; a layer of silt soft soil, a layer of sand cushion or horizontal drainage boards are stacked alternately until the top elevation of the filling bag reaches the design level; the bag body of the silt soft soil layer and the drainage sand cushion can also be seamed in a multi-layer bag Make and sew two layers of bags, that...

Abstract

A method for solidifying mud in stuff bag comprises a soft mud stuff bag, a discharging filter layer, a rubber bag, and packing material. The invention is characterized in that the soft mud stuff bag and the discharging filter layer are up-and-down alternatively layered, until the top of stuff bag reaches needed height, the rubber bag is above the stuff bag and the stuff bag and the rubber bag are packed by the packing material, while the joint is sealed by ring, then the invention fills air or water to 0.15-0.30MPa pressure into the rubber bag to compress the mud and discharge the water in the mud via upper or layer filter layer to solidify the mud. The invention can be used in the mud soft stuff bag of bank, or the like.

Description

Technical field: [0001] The invention relates to a solidification technology for silt soft soil filling bag embankment used in coastal, river embankment, revetment and waterway regulation projects. Background technique [0002] Silt soft soil is a kind of soil with high water content, low permeability coefficient, and large compression deformation. It is difficult to discharge the water in the soil and the settlement of the bag after filling is large when using this soil to fill the embankment. Technical requirements for embankment construction. The currently used fine and silt-filled bag embankment has the advantages of fast drainage and easy compaction, so it is widely used. However, with the large amount of sand resource mining, the relationship between supply and demand is becoming increasingly tense. Sometimes it needs to be mined and transported from dozens of kilometers away to the filling area for filling bags. Some areas have listed sand as a local protected resour...
