Description
Technical field
The present invention relates to transportation building engineering material, in particular to a kind of foam mud mix light-textured soil and its preparation side
Method.
Background technique
Foam lightweight soil is the novel coagulation fill material that last decade grows up, it is the foamed system by foaming machine
Foaming agent is mechanically sufficiently foamed, and foam and cement slurry and other addition materials is full and uniform according to a certain percentage
Then mixing carries out cast-in-place construction by the pumping system of foaming machine, be formed by through natural curing a kind of containing a large amount of closings
The light-duty filling material of stomata.Foam lightweight soil is since with lightweight, that intensity is adjustable, Gao Liudong, low bullet damping property are good etc. is more
The advantage of aspect, makes it have a good application prospect in traffic engineering, such as Soft Ground, cavity filling, city pipe
Corridor backfill, bridge (culvert) back filling behind abutment etc..Solve soft soil base sedimentation, bumping at bridge-head, high roadbed reclamation, save the area the problems such as
On also have significant advantage.But due to its higher cost, hardened foam light soil face checking causes to absorb a large amount of secondary waters
Point, cause service life to reduce, affects its application.
The mud roach for not having intensity largely is generated in many engineerings, these roach cannot apply to basic soil and return
It fills out, and the earthwork transportation of long range causes the loss of a large amount of economic resources.Take meet back filled foundation banket will cause it is big
The soil erosion of amount has extremely bad influence to ecological environment.Improve simultaneously the economy of backfill soil sample in engineering at
This.And China possesses a large amount of rivers, and there are a large amount of mucky soil layers for river two sides, takes at present these mucky soil layers
Measure be to take mucky soil layer to be buried nearby, this has greatly been lost national cultivated land resource and has deposited to the pollution of environment
It is seriously endangering.Another sludge treatment mode is to carry out support to mud to say, but sludge dewatering mode now only meets
Small-scale mud disposition, and processing cost is high, and the cost of projects is significantly increased.
Summary of the invention
The object of the present invention is to provide it is a kind of realize it is smaller to substructure pressure, intensity is higher, solve mud roach again
Foam mud mix light-textured soil of the advantages that utilization and preparation method thereof has industrial value.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of foam mud mix light-textured soil, calculates as mass fraction, is made of following component: raw material soil 45% ~ 50%, and water 15% ~
17%, desiccant 1% ~ 3%, cement consolidating agent 10% ~ 13%, foaming agent 12% ~ 17.5%, early strength agent 1.5% ~ 3%, thickening water-retaining agent 5% ~
7%；The raw material soil is that partial size is less than 4.5mm, and moisture content is 40% ~ 65% mud.Raw material grogs diameter is less than 4.5mm, to guarantee
There is certain pumpability through foam mud mix light-textured soil made of mixing mixing.Moisture content is 40% ~ 65% former to guarantee
Material soil has and additive mixed in level-one whipping process.
Further, cement consolidating agent is portland cement.
Further, portland cement is by 42.5 grades or more of cement and the mixture of SILICA FUME.
Further, foaming agent be α-olefin sulfonate, alkyl sulfate, three kinds of alpha-olefin sulfuric ester the inside any one
Or two kinds of mixture.
Further, desiccant is land plaster.
Further, early strength agent is the mixture of sodium sulphate and lithium carbonate.
Further, thickener is low-viscosity cellulose ether or low-viscosity cellulose.
A kind of preparation method of foam mud mix light-textured soil includes the following steps:
Step (1) acquisition mud soil sample is crushed, and is sieved to obtain partial size after broken greater than 4.75mm raw material soil.
Raw material soil obtained in step (1) is delivered to blender level-one agitator by step (2), is added water and stirred to raw material soil
Plastic limit water content be 9.5% ~ 12.5%.Its advantage is that on the basis of sufficiently mixing when the initial set of foam mud mix light-textured soil
Between be optimal state.
Step (3) weighs cement and SILICA FUME, transfers the raw material soil obtained to step (2) after completing weighing, adds
Water puts into blender second level agitator and carries out mixing mixing.
The preparation of step (4) additive: when the raw material soil and cement consolidating agent formation slurry in second level agitator, Xiang Qi
Middle addition desiccant, early strength agent, thickening water-retaining agent, sufficiently mix.
Step (5) foams to foaming agent, cement slurry and raw material of the foam in pump machine with preparation completion in step (4)
The mixture of soil is pumped to the construction part for needing to fill together.
Further, the measurement of the plastic limit water content of raw material soil uses liquid, plastic limit simultaneous determination method in step (2), takes circle
Bore the corresponding water content of embedded depth 2mm.Liquid, plastic limit simultaneous determination method precision meet site operation requirement, operation is simple,
Measuring tool is easy.
Further, the weighing of cement and SILICA FUME is claimed by the electronic induction in blender level-one material collecting barrel in step (3)
It completes.
Further, for foaming agent in foaming, the water of addition and the mass ratio of foaming agent are 60:1 in step (5).
In conclusion the invention has the following advantages:
1. the foam mud mix light-textured soil formed by above-mentioned mixing method, in the raw material soil and slurry that its broken preparation is completed
The cement consolidating agent of body form carry out it is more fully secondary mixes and stirs, avoid caused by the agglomeration of raw material soil plugging and raw material soil with
The lamination of cement consolidating agent；
2. the outer SILICA FUME and land plaster added during mixing keeps foam mud mix light-textured soil quickly solid in a short time
Knot shortens the presetting period, saves the time for pouring for upper layer；
3. being added to the portlandite that sodium sulphate and lithium carbonate form cement after aquation, make itself and sodium sulphate and lithium carbonate
In a large amount of Na+In the presence of generation chemical reaction obtains Na2O•Al2O3.The slurry made of raw material soil and cement consolidating agent mixing
In there is SiO2Chemical reaction occurs simultaneously and obtains albite.Ca in the slurry that Na+ present in albite and mixing are formed2+
Equivalent exchange is formed, slurry is made to form honeycomb cement crumb form, allows firm adhesion between each unit in entire slurry
It is formed whole；
4. being light soil by sludge treatment, utilize again, both environment was made to be improved, has saved the cost of processing mud, again
It economizes on resources, it is with good economic efficiency.
