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. The grouting 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:
This can be used for the hydro project leakage blocking and seepage-proofing, engineering fields such as the microfissure stratum of [underground, the reinforcing of porosity water exclusion of stratum.Particularly a kind of diffusion length is far away, hypertonicity, gel time is adjustable, the simple chemical soluble glass slurry for reinforcing and preventing leakage of constructing operation.
Background technology:
Hydraulic and Hydro-Power Engineering, mine engineering, geological prospecting engineering, tunnel underground opening engineering and municipal underground works are often used the slip casting method waterproofing and leakage-stopping.But there are the small slip casting problems such as aquaporin water blockoff difficulty, porosity stratum slurry infiltration difficulty of crossing in microfissure stratum in present many engineerings.Impervious blocking material now commonly used has cement based injecting paste material and cement based injecting paste material can only carry out the crack water blockoff of crack greater than 0.2mm, and cement based slurry material often need add components such as water-resisting agent, accelerating chemicals, prepares loaded down with trivial details.Department of chemistry's injecting paste material such as polyurethanes, acrylic amide, tannins and lignin or viscosity are big or have toxicity, component and reach factor engineering such as complex process more and use limited.Therefore with starting material be easy to get, avirulent water glass is that injecting paste material is an object, works out to be suitable for microfissure, porosity stratum, good penetrability, nontoxicity, the simple chemical slip casting material of composition have good using value.
Water glass is that chemical slip casting material was studied as the existing many people of nontoxicity injecting paste material, patent of invention CN 101265059A such as Li Zhiguo are the water glass solution injecting paste material of solidifying agent with sulfuric acid, slurries PH=5 acidity in the patent, have construction environment is polluted, common grouting equipment is caused defectives such as corrosion; The Guangzhou chemistry patent of invention CN 86107196A of institute is a peptizer with the vinyl acetic monomer, and other adds urea, C12-sodium alkyl benzene sulfonate composition; CN 1032354A is host with water glass, with oxalic dialdehyde, Calcium Chloride Powder Anhydrous is solidifying agent, other adds sodium tetraborate and trolamine component, causes grout coordinate ratio complicated, engineering is used stability and is difficult to shortcomings such as assurance.
Summary of the invention:
In order to solve the problem that exists in the background technology, the invention provides a kind of chemical soluble glass slurry for reinforcing and preventing leakage, this chemical pulp diffusion length water glass far away, that gel time is adjustable, hypertonicity is nontoxic is chemical slip casting material.
The technical solution used in the present invention is: this chemical soluble glass slurry for reinforcing and preventing leakage uses ethyl cellosolve acetate to be solidifying agent, water glass is host, and each component is counted by volume: in 100 parts of slurries: 15～70 parts of water glass, 2.5～14 parts of ethyl cellosolve acetates, residue component are water.
In 100 parts of above-mentioned slurries: 30～70 parts of water glass, 2.5～7 parts of ethyl cellosolve acetates, residue component are water; 70 parts of water glass, 7 parts of ethyl cellosolve acetates, water are 23 parts.
Water glass Be ' is 36～40 in the such scheme, modulus M=2.8～3.1.
Preparation method of the present invention: the water glass and the ethyl cellosolve acetate of measuring metering respectively place two containers, add the water of metering and go in the ethyl cellosolve acetate container, and two container solution are mixed, stir evenly, and wait to coagulate, and have both got the present invention.
The present invention has following beneficial effect: the present invention is a solidifying agent with water-soluble ethyl cellosolve acetate preferably, is host with water glass, controls the slurries gel time between 5S～1.5h by control slurry constituents proportioning, temperature of reaction.The slurries gel strength can be regulated by changing concentration of sodium silicate or ethyl cellosolve acetate concentration, can reach 3.0～4.5MPa.Slurry reaction mechanism at first is that ethyl cellosolve acetate hydrolysis in water medium goes out acetate, the sodium hydroxide reaction that the acetate of generation goes out with the water glass hydrolysis, and generate silicic acid gel, driving a reaction carries out to the right.Total reaction formula can be write as:
Na
2O·nSiO
2+CH
3COOCH

The invention solves existing water glass is that having improved water glass is the ultimate compression strength of injecting paste material on the problem and grouting process complicacy basis that exists in the slurries.This material can carry out effectively that hydro project is stifled oozes, and can be used for the slip casting of [underground special formation again.The present invention is not extruded successfully case after laboratory simulation pressure 12MPa, the slip casting of 1mm broad slit testing table are arranged.It is simple that the present invention has component in addition, and the proportioning modulability is good, advantages such as slurries non-corrosiveness.
Embodiment:
Below with the invention will be further described: this this injecting paste material curing mechanism is: a certain amount of water glass, add the solidifying agent ethyl cellosolve acetate, and stirring gets final product.Solidifying agent hydrolysis under alkaline condition goes out acetate, and water glass is solidified.
