The present invention proposes the grouting material of a kind of foundation stabilization, choosing portland cement is major ingredient, add the admixtures such as sulphate aluminium cement, slag micropowder, flyash, Gypsum Fibrosum, Calx, waterglass, Paris white, calcium hydroxide, low-viscosity cellulose, make serosity, by loose earth or crack cementation solidifying originally, forming new Seed harvest, the many-side such as the composition of its soil structures, seepage flow performance, chemical stability and mechanical property all changes, and has more preferable engineering properties.
Description
Technical field
The present invention relates to the grouting material of a kind of foundation stabilization.
Background technology
Slip casting also known as grouting, with force feed equipment by pressure the slurry curing materials of certain proportioning is injected into soil layer or
In crack, and spread, be gelled and solidify to form new calculus thing, be used for reinforcing soil layer and impervious leakage-stopping, built reaching building
Build engineering construction requirement.
Slurry injection technique had the history of more than 200 year, and development experience four-stage is followed successively by: (1802-1857
Year) original clay serosity developmental stage, (1858-1919) primary cement serosity developmental stage, (1920-1969) middle rankization
Learn serosity slip casting developmental stage, (after 1969) modern slip casting developmental stage.Slip casting method mainly have permeation grouting method, filling or
Crack grouting method, fracture grouting method, press injecting method, jet groutinl method and electronic chemistry slip casting method etc., cover hydrodynamics,
Numerous subjects such as chemistry, rock mechanics, soil mechanics, extensively apply in the engineerings such as traffic, water conservancy, mining, subway, tunnel, place
The aspect effects such as reason antiseepage, water blockoff and reinforcing are obvious.
In highway and railway engineering, ground usually can run into sedimentation or deformation, Carrying Capacity, needs to carry out ground
Strengthening reconstruction.Using the direct consolidation effect of Portland cement serosity the best, this is owing to serosity setting time is longer, serosity
The deficiencies such as calculus after-contraction is big, poor stability affect consolidation effect.Mix flyash, clay, volcanic ash, swelled ground, waterglass
Deng admixture, it is effectively improved the mechanical property of ordinary cement serosity, there is good stability, occur without bleed precipitation, solidification
Rear calculus is the most closely knit firm, and therefore, research novel slurry filling material becomes the key problem in technology captured.
Summary of the invention
Based on above weak point, the present invention proposes the grouting material of a kind of foundation stabilization, and it is main for choosing portland cement
Material, adds sulphate aluminium cement, slag micropowder, flyash, Gypsum Fibrosum, Calx, waterglass, Paris white, calcium hydroxide, low viscosity
The admixtures such as cellulose, make serosity and incite somebody to action loose earth or crack cementation solidifying originally, form new Seed harvest, its soil structures
The many-side such as composition, seepage flow performance, chemical stability and mechanical property all change, there is more preferable engineering properties.
In order to realize the purpose of foregoing invention, technical solution of the present invention is as follows:
The grouting material of a kind of foundation stabilization, formula is as follows: portland cement 45-55 part；Aluminium sulfate
Cement 10-14；Slag micropowder 5-8 part；Flyash 8-12 part；Gypsum Fibrosum 6-10 part；Calx 5-8 part；Waterglass 8-10 part；Calcium carbonate
Powder 3-5 part；Calcium hydroxide 0.6-1.2 part；Low-viscosity cellulose 0.02-0.03 part；Extender 3-6 part；Water reducer 1-1.5 part.
The present invention also has a following technical characteristic:
Further, described portland cement is the Portland cement that strength grade is higher than 42.5, and portland cement is
Grouting major ingredient, shortens setting time, for the premise of regulation setting time；Described sulphate aluminium cement is that strength grade is higher than 42.5
Sulphate aluminium cement, in early days rapid condensation hardening, strengthen early strength, regulate setting time.
Further, described fineness of slag is 300-450 mesh, and specific surface area is 500-700m2/ kg, can increase service life,
Strengthen impermeability and the sulfate resistance of Seed harvest after grouting material hardens.
Further, described waterglass is solid sodium silicate.
Further, described Paris white fineness is 350-500 mesh.
Further, described calcium hydroxide fineness is 600-700 mesh.
Further, described low-viscosity cellulose viscosity is 100-300mpa s, for preventing the layering of composite with heavy
Fall.
Further, described extender is calper calcium peroxide, sodium peroxide and calcium sulphoaluminate mixture, and mass ratio is 2-4:2-3:
2-5, fineness is 300-400 mesh, and calper calcium peroxide compensates for early-age plastic shrinkage, and sodium peroxide is for shrinkage-compensating in mid-term, sulfur
Calcium aluminate compensates for final set after-contraction.Composite expanding agent can compensate for cement grouting material and shrinks, material microdilatancy, body after grouting
Long-pending more stable.
Further, described water reducer is polycarboxylate water-reducer, and water-reducing rate is 25-35%, and water-reducing rate is high, has good with cement
The good compatibility, can reduce amount of water, increases composite fluidity.
During use, need to add a certain amount of water, make serosity, water content is 14-22%.
Different according to water content, serosity fluidity is different, and physico mechanical characteristic index is different.In test, according to required
The difference of fluidity, regulates amount of water and proportioning raw materials.
Grouting material is in construction, first by proportioning by the raw material of constant weight and water mixing and stirring, it is ensured that serosity
Fluidity more than 150mm, closer for transportation range, will be stirred the static 15min of serosity can carry, for transport away from
From distant, pumping mode can be used.
The composite of proportioning of the present invention can improve the comprcssive strength of the soil body, and solution cement grout exists contraction fissure and asks
Topic, can effectively control the expansion rate of the soil body, and expansion rate, within 0.5%, has small expansion but will not produce spalling, to reach ground
Base is reinforced, is prevented the requirements such as crack.
The grouting grout cures of the present invention is fast, scalable setting time, engineering time are short, and consolidation effect is good, Seed harvest is strong
Degree is high, material loss is few, effect is very fast, it is easy to construct, noise is little in construct simple, low cost, work progress, the vibration that produces
Weak, little to surrounding environment influence, can be applicable to operating surface than narrow sitework, the degree of depth of grouting and reinforcing can be according to needs
Control the depth, be widely used in the fields such as traffic engineering, civil engineering, tunnel, water conservancy and hydropower, hypogee, bring huge
Economic benefit and social value.
