Study on Polymer Grouting Reinforcement Technology and its Application
Polymer grouting technology can realize the treatment of various diseases,such as foundation rein-forcement,collapse filling,floor jacking,and leakage plugging.At present,it has been widely used in engineering fields such as high ways,tunnels,bridges,embankments,and has achieved remarkable economic,social and ecologi-cal benefits.The technical core of polymer grouting is two-component foamed polyurethane material,which has the characteristics of good expansibility and controllability,fast and adjustable reaction speed,light weight,environmen-tal protection and durability.It plays an important role in civil engineering,water conservancy and other engineering construct ion,repair and reinforcement.The shear,tension compression and dynamic properties of polymer materials are tested and analyzed.It is found that the slurry density is an important factor affecting the mechanical properties of polymer materials.The higher the density of polymer slurry,the smaller the cell surface area after forming,the lower the surface energy,the more stable the molecular system,and the better the shear,tension compression and dy-namic properties.Finally,the application of polymer grouting technology in reinforcement and flood control is ex-plained,and the bottleneck and research prospect in its development are discussed and analyzed.The popularization and application of polymer grouting technology will improve the quality and level of water conservancy,civil engi-neering,mining and other engineering projects.
