Chemical soluble glass slurry for reinforcing and preventing leakage

Abstract

The invention is a chemical soluble glass slurry for reinforcing and preventing leakage. The chemical slurry uses ethylene glycol monoethyl ether acetate as curing agent and soluble glass as main component. Based on 100 parts of slurry, the volume ratio of each component is as follows: 15-70 parts of soluble glass, 2.5-14 parts of ethylene glycol monoethyl ether acetate and water for the rest. Thegrouting material has the characteristics of large dispersion range, good penetration, adjustable curing time, simple operation, and the like. The slurry gel is nontoxic and has relatively higher pressure resistance. The invention can be widely used for preventing leakage in dam foundation, and has broad application prospect in water blocking and reinforcing project.

Description

Technical field: [0001] The invention can be used in water conservancy project plugging and anti-seepage, engineering fields such as water plugging and reinforcement of micro-cracked formations and porous formations in mine construction. In particular, a water glass reinforced plugging chemical slurry with long diffusion distance, high permeability, adjustable gel time and simple construction operation. Background technique: [0002] Water conservancy and hydropower projects, mine projects, geological exploration projects, tunnel underground chamber projects and municipal underground projects often use the grouting method for waterproofing and plugging. However, there are currently many grouting problems in many projects, such as the difficulty of water blocking in micro-cracked formations and the difficulty of water penetration in porous formations. Currently commonly used anti-seepage and plugging materials include cement-based grouting materials and cement-based grouting...

[0003] Water glass series chemical grouting material has been studied by many people as non-toxic grouting material. Invention patent CN 101265059A such as Li Zhiguo uses sulfuric acid as the water glass solution grouting material of curing agent. The environment causes pollution, causing defects such as corrosion to common grouting equipment; Guangzhou Institute of Chemistry invention patent CN 86107196A uses ethyl acetate as a coagulant, and additionally adds urea and C12-sodium alkylbenzene sulfonate components; CN 1032354A uses water glass as a coagulant As the main agent, glyoxal and anhydrous calcium chloride are used as curing agents, and sodium tetraborate and triethanolamine are added, which leads to complex slurry preparation and difficulty in ensuring the stability of engineering applications.
