Drainage system using water drainable and permeable member for soil improvement of soft ground and soil improvement method for soft ground using the same

Abstract

The present invention relates to a water drainable and permeable drainage system and method for treatment of soft ground, which enable surface layer treatment of soft ground by installing open channels and collector wells of water drainable and permeable members on soft ground to drain surface water and subsurface simultaneously in order to remove surface water and subsurface water of soft groundcreated by dredging and filling, etc. The open channel is formed in a coverless type composed of sides and a floor surface without a cover, and the collector well is also formed in a coverless squarebody composed of sides and a floor surface. A frame structure is formed in a mesh form with metal material or synthetic resin material, and the outside is covered with permeable filter material and surface water flow holes are formed in the upper portion. Therefore, the manufacturing cost is reduced, and by adding and forming a plurality of surface water flow holes and styrofoam for buoyancy generation and heavy objects for buoyancy control, surface water and subsurface water are drained simultaneously with easy installation, so excellent installation is possible even on ground in a soft sludge condition.

Description

technical field [0001] The present invention relates to a drainable, permeable drainage system and method for treating soft soil foundations, by which surface water and groundwater can be drained simultaneously by installing open channels and sump wells using drainable, permeable components Drain to remove water from excavation and landfills on and below the surface of soft soil foundations. Background technique [0002] The soft ground of excavated and filled land is in the state of mud and therefore highly deformable, and because of this, the soil has a low load-bearing capacity. [0003] In the case of installing a conventional heavy-body drainage structure on a soft ground having a low load-bearing capacity, it is impossible to install and form a heavy-body drainage structure. And even if traditional open channels and catch wells could be installed, they are limited by the fact that only surface water is collected and drained and that there is a large amount of silt flo...

AI Technical Summary

Problems solved by technology

[0002] The soft soil foundation of excavated and filled land is in the state of mud and therefore has high deformability and because of this, the soil has a low load-bearing capacity

[0003] In the case of installing a conventional heavy object drainage structure on a soft ground with a low load-bearing capacity, it is impossible to install and form a heavy object drainage structure

And even if traditional open channels and catch wells could be installed, they are limited by the fact that only surface water is collected and drained and that there is a large amount of silt flowing into the drainage channels

[0004] In addition, although there are drainage materials made of pipe bodies connected horizontally and vertically, there are still the following problems: the production cost increases due to its structure when the drainage material is formed; and the amount of water to be discharged may be smaller than an open channel; and due to the need to improve the shallow layer of the soft ground, the project cost will be high
