Abstract

See full text

A karst channel type water inrush efficient-blocking ultra-high expansion grouting material, preparation, methods and application thereof, the grouting material includes macromolecule polymer particles A and a cross-linking solidifying fluid B, wherein the macromolecule polymer particles A are an inlaid type core-shell structure, primary macromolecule water-absorbent resin serves as an inner core, part of a gelling catalyzer is attached to an the inner core surface forming a shell, and the gelling catalyzer permeates the inner core forming an inlaid structure; before use, the macromolecule polymer particle A and the cross-linking solidifying fluid B are stirred; and then obtained mixed liquid is used as the grouting material to be injected into a fracture of a rock mass fracture zone. By means of the grouting material, high-pressure large-flow karst water inrush can be efficiently treated, the blocking efficiency of water inrush is improved, and major underground engineering construction of China is further facilitated.
