A Composition for Reinforcing Soft Ground and Restoring Depressed structures including Urethane for Solidifying Ground and Construction Methods Using Thereof

摘要

The present invention relates to a composition for reinforcing soft ground and restoring subsided structures including urethane for solidifying the ground which, based on 100 parts by weight of an oleophilic resin, comprises the following: 10 to 30 parts by weight of a polyol compound; 5 to 20 parts by weight of an isocyanate compound; 1 to 15 parts by weight of a foaming agent; 3 to 15 parts by weight of an amine compound; 1 to 10 parts by weight of a surfactant; 1 to 10 parts by weight of a dispersant; 2 to 20 parts by weight of a binder; and 3 to 15 parts by weight of nanoceramic particles. The present invention also relates to a construction method using the composition. The composition for reinforcing soft ground and restoring subsided structures contains urethane for solidifying the ground, etc., thereby being effective in completing a reinforcement and restoration work in a short time by a simple construction using the piercing.
