Abstract
The invention discloses a bubble mixing light earth and the making method, the weight percentage of its components; cement 12-55%, arenaceous earth 0-66%, mixed water 21-40% and bubble 1-5%; making mixing and stirring ont he above three components and the pre-made bubble to get it.
Description
Affiliated technical field
The present invention relates to a kind of air bubble mix light-textured soil that is used for fields such as highway engineering, Tunnel Engineering and bridge construction; The making method that also relates to this air bubble mix light-textured soil.
Background technology
At present, domestic Expressway Ground Improvement is adopted various consolidations (surcharge preloading method, vacuum method, preloading are arranged) to promote sedimentation basically, improves the bearing capacity of soft base, for example, the Soft Foundation with Deep and Thick Silt Layer that the Delta of the Pearl River, area, Yangtze River Delta distribute is passed through construction plastic draining board, packed husky well, carry out methods such as preload then; These methods can make the primary consolidation sedimentation be controlled in the construction time basically and finish, because the creeping property of soft clay causes secondary consolidation settlement, though this sinkability ratio in total settlement is little, ratio shared in settlement after construction is generally bigger, and required time of sedimentation is long.In order to shorten the construction period, to reduce settlement after construction, also often adopt the surcharge preloading method, and this method not only increases executive cost, can not fundamentally eliminate the generation of settlement after construction; Also have in addition and use the flyash roadbed that constructs a railway, but, can't use as the householder method of treatment of soft foundation fully because the unit weight of coal ash soil is still bigger; Also have some that plastic grain is mixed with soil, the end of the bridge of one motorway once had and uses light-duty wall brick factory scrap stock to carry out the light-duty example that bankets as material in Jiangsu; Also once had ultra-light material EPS was applied to the construction example that end of the bridge bankets, but EPS is a kind of chemical materials of costliness, not only the cost height need be treated to a large amount of construction waste soil of filling EPS and excavating out, and the unit weight (0.016～0.03t/m of this material
3) too little, must consider the stability problem that buoyancy of water etc. causes.
Summary of the invention
The object of the present invention is to provide a kind of density can regulate less than general high-quality soil, intensity, can alleviate the pressure that bankets, sedimentation and the lateral flow that suppresses soft base, and the air bubble mix light-textured soil that can vertically banket, another purpose is to provide a kind of method of making this air bubble mix light-textured soil.
The object of the present invention is achieved like this, and a kind of air bubble mix light-textured soil contains weight ratio when moistening be 12%～55% cement, 0～66% sandy soil, 21%～40% mixing water, 1～5% bubble.Under the drying regime, the void volume by bubble formation in the air bubble mix light-textured soil accounts for 40%～65% of cumulative volume.
The concrete steps of said components being made air bubble mix light-textured soil are:
A, sandy soil is carried out pre-treatment; By sandy soil is sieved foreign material such as boulder and fragment of brick in the sandy soil are removed, filter out the sand of certain particle diameter;
B, get sandy soil, cement and water, mix into sand-cement slurry with stirrer by described part by weight;
C, adding dilution water dilution in pore forming material are poured pressurized air again in the pore forming material of dilution, produce bubble population;
D, the sand-cement slurry of getting the bubble population of step c and step b by described part by weight stir, and uniform mixing obtains air bubble mix light-textured soil.
The described cement of above-mentioned steps is trass cement, ordinary Portland cement or blast-furnace portland cement, also can add assistant agents such as flyash, terra alba, silica flour in described cement.
The described pore forming material of above-mentioned steps is interfacial activity class, protein, resinous material.
Air bubble mix light-textured soil of the present invention is because it has characteristics such as light weight, flowability and self-hardening property, not only can alleviate the pressure that bankets, the sedimentation and the lateral flow that suppress soft base, and the earth pressure that works such as abutment and retaining wall are born behind significantly reduces.Works such as the expanding that air bubble mix light-textured soil can be widely used in roadbed bankets, banketing on the soft base, abutment and retaining wall banket behind, and its concrete advantage is as follows:
1. light weight
The moistening density of air bubble mix light-textured soil is at 0.5～1.3g/cm
3Between, can cooperate the density of control soil recently by adjusting according to different purposes.
2. mobile
Air bubble mix light-textured soil can transport by the mode that pump pressure is sent, and maximum is transported distance can be big 500 meters.
3. application property
Air bubble mix light-textured soil has mobile high characteristics, and not only can grow distance and carry, and also evenly filling freely, do not need compacting operation, make the fill construction of narrow working space become easy.
4. the controllability of intensity
By adjusting the addition of stable material, can be with the uniaxial compressive strength of air bubble mix light-textured soil at 300～1000kN/m
2Freely control (the uniaxial compressive strength that generally bankets: 300～1000kN/m in the scope
2).
5. the independence after solidifying
Air bubble mix light-textured soil can be supported oneself after solidifying, and can carry out vertical fill construction.
6. weather resistance
A large amount of experiments show that the long durability of air bubble mix light-textured soil is very high.
7. uniformity
By stirring each composition of air bubble mix light-textured soil is distributed in heterogeneity.
8. thermal insulation
The bubbles volume of air bubble mix light-textured soil (voidage) is big, has the function of certain lagging material.
9. water-permeable
The water-permeable of air bubble mix light-textured soil is very little.
Embodiment
Embodiment one
1, gets the sandy soil 400Kg of foreign material such as removing boulder and fragment of brick;
2, get fire mountain ash concrete 300Kg, mixing water 270Kg pour three kinds of components in the stirrer into and to mix again; That trass cement mainly plays a part is fixed, strengthen soil body skeleton, also replacement such as the ordinary Portland cement of available equivalent or blast-furnace portland cement of trass cement, and these materials add and water take place between back and the water in burying and effect produces Ca (OH)
