Soluble glass slurry taking water-soluble ester as curing agent

Abstract

The invention relates to a soluble glass slurry taking water-soluble ester as curing agent. The soluble glass slurry taking water-soluble ester as curing agent uses carbitol acetate as curing agent; the main agent is soluble glass; based on 100 parts of slurry, the volume ratio of each component is as follows: 15-60 parts of soluble glass 38Be', 1-8 parts of carbitol acetate, and water for the rest. The invention is suitable for water plugging of water-bearing layer of quartz sandstone and grouting at the back of the well wall, and is particularly suitable for ground pregrouting and face pregrouting of porous stratum of the pit shaft of mine well; the invention takes carbitol acetate with excellent dissolving performance as curing agent; the grouting material has the characteristics of high permeability, high strength, adjustable gel time, and the like, has simple operation, easy storage and stable performance, and is chemical grouting material with high application value.

Description

Technical field: [0001] The invention relates to a sodium silicate chemical grouting material, which can be used for ground pre-grouting, working face grouting and back grouting of shaft wall for water blocking in mine construction. Background technique: [0002] The mining depth of mineral resources is getting deeper and deeper, and the difficulty of blocking water in mine construction is becoming more and more difficult. The effect of traditional ground pre-grouting is sometimes not ideal, which increases the cost of well construction and prolongs the construction period. Therefore, research on an ideal grouting material has great application value. Especially for deep wellbore, ordinary grouting materials are difficult to achieve the water shutoff effect. For special single aquifer formations such as micro-cracks and porosity, the present invention, which has stable performance and is easy to manipulate, is a good grouting material. This material can achieve higher ground pre...

Problems solved by technology

[0003] The economical sodium silicate chemical grouting material has a wide range of research areas. The research results of CN 101265059A, CN86107196A and CN 1032354A are limited in application due to material corrosion or complex composition and difficult control of stability.

Urea-formaldehyde resin slurries, which are widely used, are also difficult to popularize to a certain extent due to defects such as many components, difficulty in long-term storage, and high viscosity.
