Description
Technical field
The present invention relates to a kind of polyurethane cement composite grouting material.Be applicable to the shutoff of big flow water burst, the filling and the reinforcing in rock and concrete crack, building foundations such as dam, bridge, building reinforce and soil stabilization is handled.
Background technology
Grouting technique is divided into by the difference of forming slurry material: cementation process, sand-cement slurry grouting, clay grouting, cement clay grouting, cement-sodium silicate grouting and macromolecular solution chemical grouting.Up to now, cement is still most widely used basic material in the grouting work.During grouting treatment, should at first consider to select for use cement grouting material, demonstration is thought when adopting cement grouting material not solve engineering problem after deliberation, just considers to select for use chemistry to irritate material.This be because: (1) cement grouting material can satisfy the requirement of consolidation grouting, joint grouting and the curtain grouting of common engineering.(2) cement is inorganics, and its staple is the oxide compound of silicon, calcium, aluminium, iron, magnesium, sodium, potassium, manganese etc., does not have the toxic chemical substance that causes environmental pollution in the cement grouting material component.(3) the cement grouting material price processed of ordinary Portland cement is more much lower than chemical grouting material., because cement grouting material metal particles type material, can not obtain satisfied effect to the processing of some micro-cracks.In addition, to the leakage area of certain flow rate is arranged, priming charge mud is easy to by the water dilution before solidifying or washes away.The application that these all make cementation process has received certain restriction.Chemical grouting material is a true solution, and viscosity is low, and concrete castability is good, and seepage force is strong, and filling is closely knit, good waterproof performance, and the fixed back of slurry material intensity is high, and the gel time degree of amplitude modulation is big, and bonding strength is also high.Therefore, to the unsatisfactory grouting works of cement grouting material, multiselect is used chemical grouting material.At present the kind of chemical grouting material is a lot, as epoxy, first coagulate, third coagulate, acrylate, acidity and alkaline water glass, water-soluble and oil soluble polyurethane, urea-formaldehyde resin, chrome lignin etc., but also in continuous increase.Wherein the urethane injection material is the important injection material that is widely used in rising in the engineerings such as water conservancy, water power, tunnel, subway, mine, people's air defense, industry and covil construction antiseepage, leak stopping, reinforcement effect.
Polyurethane-reinforcement is irritated material has oil soluble (also claiming hydrophobic nature) and water-soluble (also claiming wetting ability) two big types; Free-NC0 group content in the oil soluble polyurethane is high, under the condition of selecting appropriate catalyst, and reaction rapidly behind the chance water; Will foamed solidification in several seconds～tens seconds; In confined conditions, just can generate ultimate compression strength in several hours and reach the above induration of 20MPa, the big flow water burst of blocking high-pressure proves effective especially.Therefore leak to high pressure is especially big, it should be a preferred material, but it is a macromolecular material, compares with the mineral-type cement material, and it is high that its price is wanted.
Summary of the invention
The technical problem that the present invention will solve is: a kind of polyurethane cement composite grouting material is provided; Be intended to urethane slurries and grout are re-dubbed composite grouting material, bring into play both chiefs, both cost-saved; Help the environmental protection of constructing again, and can reach the purpose of quick, effective water blockoff.
The technical scheme that the present invention adopted is: polyurethane cement composite grouting material, it is characterized in that forming by A, the two components of B, and composition of raw materials is distinguished as follows:
The A component:
Oil soluble polyurethane injection material 100 weight parts
Catalyzer 1～10 weight part
Silane coupling agent 0.5～2 weight part
The B component:
Cement 100～200 weight parts
Water 30～100 weight parts
Water reducer 0～10 weight part
Tensio-active agent 1～5 weight part;
A component raw material stirred in proportion is made into A liquid, and the slurry storing tank of packing into is put into the grout mixing apparatus in proportion with B component raw material again and stirred and be made into B liquid, another slurry storing tank of packing into;
With two inlet pipes of automatic variable grouting equipment respectively hand go in two slurry storing tanks; In A liquid: the cooperation ratio of B liquid=1: 0.5～3 is regulated grout absorption; The mixing process of two kinds of slurries can realize at the bottom of aperture or hole in the slip casting process; Through static mixing device, two components are mixed, and deliver to indication position, bonding part through pressure pump.
Said oil soluble polyurethane injection material is usual vehicle type or environment-friendly solvent type polyurethane injection material, in the slurries content of isocyano group 15～22%, viscosity 150～450mPas.
Said catalyzer is independent tertiary amine catalyst or tertiary amine catalyst and organotin catalysts compound catalyzer mutually.
Said silane coupling agent is the 3-glycidyl ether oxygen propyl trimethoxy silicane.
Said cement is ordinary Portland cement.
Water reducer is a naphthalene series high-efficiency water-reducing agent.
Said tensio-active agent is an aniorfic surfactant.
The invention has the beneficial effects as follows: this injection material is compared chance water and can be reacted rapidly with Portland cement class injection material, quick solidifying, and concretion body strength is high, and is effective to the big flow water burst of blocking high-pressure, and overcome grout easy shortcoming that runs off under moving water state; And compare with traditional urethane injection material, it both can practice thrift cost, and the environmental protection that helps again constructing makes the intensity of induration be improved again simultaneously, and therefore effect is more obvious when being used for the strengthening of foundation processing.Cement composite grouting material of the present invention is highly suitable for the shutoff of the big flow water burst in water conservancy, water power, tunnel, subway, mine, people's air defense, industry and the civil building engineering, and the quick reinforcing of rock stratum, ground and soil stabilization are handled.
