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

摘要

The present invention relates to a composite for the reinforcement of soft ground and the recovery of a sunken structure and a construction method using the same. Based on 100 parts by weight of cement, the composite includes: 10-40 parts by weight of calcium sulfo-aluminate; 20-50 parts by weight of glycidyl methacrylate (GMA) resin; 10-70 parts by weight of a polyol compound; 5-40 parts by weight of an isocyanate compound; 2-20 parts by weight of a blowing agent; 5-20 part by weight of an amine compound; 1-10 parts by weight of a surfactant; 1-10 parts by weight of a dispersant; 2-20 parts by weight of an accelerating agent; 2-20 parts by weight of a bonding agent; 3-15 parts by weight of nanoceramic particles; and 0.1-10 parts by weight of water reducing admixture. Thus, the present invention is capable of completing reinforcement and recovery work for a short time through simple construction making holes with the composite.
