A Composition for Reinforcing Pile of Reinforcing Soft Ground and Restoring Disparity Sinking Construction Comprising Urethane for Solidifying Ground and Constructing Methods Using Thereof

摘要

The present invention relates to a composition for a reinforced pile and a construction method thereof. The composition for a reinforced pile of the present invention comprises: based on 100 parts by weight of a polymer resin, 20 to 80 parts by weight of a polyol compound; 10 to 60 parts by weight of an isocyanate compound; 5 to 20 parts by weight of an amine compound; 1 to 10 parts by weight of a surfactant; 5 to 30 parts by weight of re-emulsification type polymer powder; 1 to 10 parts by weight of a dispersant; 3 to 40 parts by weight of fiber; 2 to 20 parts by weight of a bonding agent; and 3 to 15 parts by weight of nanoceramic particles. According to the present invention, the reinforced pile can be manufactured by using the composition for the reinforced pile for reinforcing poor ground and restoring a subsided structure. Also, reinforcement and restoration operations can be completed in a short period of time based on simple construction using the composition. Further, according to the present invention, damage of human life and property can be prevented by reinforcing ground under and around an underground structure comprising subways, drainages, underground commercial facilities, and underground power stations, which is poor due to construction of the underground structure and by reinforcing ground which becomes poor over time or due to poor compaction of embankment which is embanked in the construction of housing sites, roads, and railways.
