Vacuum sludge filling bag

Abstract

The invention discloses a vacuum sludge filling bag and relates to equipment for a cofferdam in a coastal reclamation project and a project of land reclamation by mud hydraulic. The vacuum sludge filling bag comprises a bag body and sludge filled in the bag body, wherein drain boards arranged at intervals are uniformly fixed at the bottom of the bag body, and connected into a circle through double-hand board joints at the upper parts of the drain boards; each double-hand board joint comprises connecting pipe sections at two ends, a straight pipe in the middle, and two hollow case bodies vertically communicated with the straight pipe in the middle; the drain boards are inserted into the hollow case bodies; the two connecting pipe sections of each double-hand board joint are connected with a vacuumizing pipe; when the bag is in use, a complete vacuum system can be formed in the bag; the sludge can be separated from water within a relatively short time; the sludge in the bag is solidified rapidly; and a trapezoid dam body and the cofferdam formed by overlying several layers of bags are good in sealability, and are not easily pervious to water; the safety of the dam body is improved; low carbon and environmental protection are realized; resources are saved in deed; and the vacuum sludge filling bag is applicable to the coastal reclamation project and the project of land reclamation by mud hydraulic.

Description

technical field [0001] The invention relates to equipment for cofferdams of land reclamation from the sea and land reclamation by dredging and filling mud, in particular to a vacuum flushing mud bag for flushing mud into the bag for consolidation and stacking layers to form a dam body. technical background [0002] Sand washing bags are widely used in land reclamation and silt land reclamation projects in China, which contain sea sand and river sand. Due to the rapid formation of sand permeability, they are made into cofferdams and dam bodies. However, due to the lack of sand resources, The cost of land reclamation is getting higher and higher, and a lot of marine ecology is destroyed. Therefore, in order to achieve low-level environmental protection, silt is used instead of sand to fill cofferdams and dams. [0003] Since the sludge is filled in the bag, the sludge needs to be consolidated, and vacuuming is a better solution. Contents of the invention [0004] The presen...

[0002] Sand washing bags are widely used in land reclamation and silt land reclamation projects in China, which contain sea sand and river sand. Due to the rapid formation of sand permeability, they are made into cofferdams and dam bodies. However, due to the lack of sand resources, The cost of land reclamation from the sea is increasing, and a large amount of marine ecology is destroyed. Therefore, in order to achieve low-level environmental protection, silt is used instead of sand to fill cofferdams and dams.
