Document Type and Number:
WIPO Patent Application WO/2018/151583
Kind Code:
A1
Abstract:
A soft ground improvement method is disclosed. The present invention is implemented through the steps of: forming a plurality of foundation piles in the soft ground by using high-density polyurethane; constructing stabilized soil mat on the provided foundation piles; constructing a replacement layer on the constructed stabilized soil mat; laying broken stones on the constructed replacement layer, and then providing conical piles according to the positions of arranged reinforced bars; filling an area around the provided conical pile with the broken stones; and constructing a finishing layer on the provided conical piles. According to the present invention, provided is the soft ground improvement method ensuring a required supporting force for an upper load of a design structure on the ultra-soft ground, restraining lateral deformation, and being capable of ensuring economical and environmental benefits.
