The present invention proposes a kind of grouting material of foundation stabilization, selection portland cement is major ingredient, add the admixtures such as sulphate aluminium cement, slag micropowder, flyash, gypsum, lime, waterglass, Paris white, calcium hydroxide, low-viscosity cellulose, slurries are made, by script loose earth or crack cementation solidifying, new Seed harvest is formed, the various aspects all have been changed such as ingredient, seepage flow performance, chemical stability and mechanical property of soil structures has better engineering properties.
Description
Technical field
The present invention relates to a kind of grouting materials of foundation stabilization.
Background technology
Slip casting also known as be in the milk, with force feed equipment by pressure by the slurry curing materials centainly matched be injected into soil layer or
In crack, and new calculus object is spread, is gelled and is formed by curing, for reinforcing soil layer and impervious leakage-stopping, is built with reaching building
Build engineering construction requirement.
Slurry injection technique had more than 200 years history at present, and development experience four-stage is followed successively by：(1802-1857
Year) original clay slurries developing stage, (1858-1919) primary cement slurries developing stage, (1920-1969) middle rankization
Learn slurries slip casting developing stage, (after 1969) modern slip casting developing 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 chemical slip casting method etc., cover hydrodynamics,
Numerous subjects such as chemistry, rock mechanics, soil mechanics, the extensive use in the engineerings such as traffic, water conservancy, mining, subway, tunnel, place
It is with obvious effects to manage antiseepage, water blockoff and reinforcing etc..
Ground can usually encounter sedimentation or deformation, Carrying Capacity in highway and railway engineering, need to carry out ground
Strengthening reconstruction.It is bad using the direct consolidation effect of Portland cement slurries, this is because slurries setting time is longer, slurries
The deficiencies of calculus after-contraction is big, stability is poor influences consolidation effect.Mix flyash, clay, volcanic ash, swelled ground, waterglass
Equal admixtures, are effectively improved the mechanical property of ordinary cement slurries, with good stability, do not occur bleed precipitation, solidify
Calculus is more closely knit firm afterwards, and therefore, research novel slurry filling material becomes the key problem in technology captured.
Invention content
Based on the above shortcoming, the present invention proposes a kind of grouting material of foundation stabilization, chooses based on portland cement
Material, addition sulphate aluminium cement, slag micropowder, flyash, gypsum, lime, waterglass, Paris white, calcium hydroxide, low viscosity
The admixtures such as cellulose are made slurries by script loose earth or crack cementation solidifying, form new Seed harvest, soil structures
Many-sided all have been changed such as ingredient, seepage flow performance, chemical stability and mechanical property, there is better engineering properties.
In order to realize that the purpose of foregoing invention, technical solution of the present invention are as follows：
A kind of grouting material of foundation stabilization, formula are as follows by weight ratio：45-55 parts of portland cement；Aluminium sulfate
Cement 10-14；5-8 parts of slag micropowder；8-12 parts of flyash；6-10 parts of gypsum；5-8 parts of lime；8-10 parts of waterglass；Calcium carbonate
3-5 parts of powder；0.6-1.2 parts of calcium hydroxide；0.02-0.03 parts of low-viscosity cellulose；3-6 parts of swelling agent；1-1.5 parts of water-reducing agent.
The present invention also has following technical characteristic：
Further, the portland cement is the Portland cement that strength grade is higher than 42.5, and portland cement is
Be in the milk major ingredient, shortens setting time, the premise adjusted for setting time；The sulphate aluminium cement is that strength grade is higher than 42.5
Sulphate aluminium cement, for early stage rapid condensation harden, enhance early strength, adjust setting time.
Further, the fineness of slag is 300-450 mesh, specific surface area 500-700m2/ kg can increase service life,
Enhance the impermeability and sulfate resistance of Seed harvest after grouting material hardens.
Further, the waterglass is solid sodium silicate.
Further, the Paris white fineness is 350-500 mesh.
Further, the calcium hydroxide fineness is 600-700 mesh.
Further, the low-viscosity cellulose viscosity is 100-300mpas, for prevent the layering of composite material with it is heavy
Drop.
Further, the swelling agent is calper calcium peroxide, sodium peroxide and calcium sulphoaluminate mixture, mass ratio 2-4:2-3:
2-5, fineness are 300-400 mesh, and calper calcium peroxide is compensated for early-age plastic shrinkage, and sodium peroxide is used for mid-term shrinkage-compensating, sulphur
Calcium aluminate is compensated for final set after-contraction.Composite expanding agent can compensate for cement grouting material contraction, material microdilatancy, body after grouting
Product is relatively stablized.
Further, the water-reducing agent is polycarboxylate water-reducer, and water-reducing rate 25-35%, water-reducing rate is high, is had with cement good
Good compatibility can reduce amount of water, increase composite fluidity.
In use, a certain amount of water need to be added, slurries, water content 14-22% is made.
According to water content difference, slurries fluidity is different, and physico mechanical characteristic index is different.In test, according to needed for
The difference of fluidity, to adjust amount of water and raw material proportioning.
The raw material of constant weight is mixed evenly with water according to the ratio first in construction for grouting material, ensures slurries
Fluidity be more than 150mm, it is closer for transportation range, will be stirred the static 15min of slurries i.e. can transport, for transport away from
From distant, pumping mode can be used.
The compression strength of the soil body can be improved in the composite material that the present invention matches, and solving cement grout, there are contraction fissures to ask
Topic, can effectively control the expansion rate of the soil body, and expansion rate has small expansion but not generate spalling, to reach ground within 0.5%
Base is reinforced, prevents the requirements such as crack.
The grouting grout cures of the present invention are fast, setting time is adjustable, the construction time is short, and consolidation effect is good, Seed harvest is strong
Degree is high, material loss is few, effect is very fast, is easy to the vibration that construction, construction is simple, at low cost, noise is small in work progress, generates
It is weak, small to surrounding environment influence, operating surface is can be applied to than narrow sitework, and the depth of grouting and reinforcing can be according to needs
The depth is controlled, is widely used in the fields such as traffic engineering, civil engineering, tunnel, water conservancy and hydropower, hypogee, brings huge
Economic benefit and social value.
