Description
Technical field
The present invention relates to a kind of civil construction material, and in particular to a kind of premixing fluidised form solidified earth.
Background technology
At present during the construction of all kinds of engineerings in China, the place in terms of the improvement soil body, soil mass consolidation is often run into
Reason demand, such as basement process, subgrade strengthening etc., also frequently encounter the cast for privileged sites such as mine worked-out section, grooves
Construction operation in terms of backfill.For these construction demand, at present used by practitioner in design and construction method, all
Have some limitations.For example deep mixing method is mostly used for basement process, by being filled in the soil body in the original location into water
Action of forced stirring is carried out after the curing agent such as mud makes it be combined with the soil body to improve intensity, but this mix in situ flows due to lacking
It is uneven with the reason mix such as operating space and plant equipment, and cause the intensity after processing relatively low, for pattern foundation pit supporting structure curtain
Curtain wall is then more difficult to pile；For trench backfill and highway subgrade, handled more using sixteen dirt, 37 lime earth backfill, or
Person directly replaces the soil body using materials such as concrete, and complex procedures, cost are very high and cause largely to waste；Mine worked-out section, base
The special areas such as groove, fertile groove, all it is directly to be backfilled using industrial wastes such as mine tailings or using concrete, construction faciostenosis construction is tired
Difficulty, and construction costs is very high.
Still further aspect, in the dealing with foundation of all kinds of engineerings such as harbour, road, mine, urban construction, opened
The annual quantity of the soil, the dregs that dig, displace may be up to more than ten00000000, tens billion cubic meters, these soil, the dregs overwhelming majority
It is not efficiently recovered and utilizes, and be regarded as discarded object and bank up, abandon, therefore causes large amount of land resources and soil to provide
The waste in source, and secondary pollution easily is caused to surrounding environment.
Therefore, how it is maximally effective utilize these natural rock-filleds, and can improve soil capability with meet it is above-mentioned it is complicated,
Extensive construction needs, but also to reach cost-effective, reduces construction period, reduces the good result of working procedure, not only
It is current Geotechnical Engineering field, is also the key subjects that whole building industry all suffers from.
The content of the invention
To solve the above problems, the present invention provides a kind of premixing fluidised form solidified earth, the solidified earth main component is construction slag
Soil and industrial waste, cost is cheap and intensity is up to standard, it is characterised in that is reached according to the different adjustment ratios of engine request and soil nature
To the intensity, permeability and volume stability of needs, it can be used in foundation stabilization, trench backfill, highway subgrade, pattern foundation pit supporting structure curtain
Curtain wall, mine worked-out section backfill, the premixing fluidised form solidified earth are composed of the following components according to mass percent：
Water 15~18%
Soil 60~92%
Composite solid material 2.66~13.33%
Cement 5.33~26.66%.
Described water is industrial water, agricultural water.
Described soil be the natural earth such as mud, clay, silty clay, silt, sand, fine sand, middle sand or building waste again
Fecula and the two is compound.
Described composite solid material is a kind of by active silica-alumina material and dispersant, crystallization derivant, exciting agent and micro-
The powder body material of swelling agent composition, wherein active silica-alumina material account for 60%~70%, are levigate gangue, ground steel slag, levigate ore deposit
Slag, flyash, red mud, levigate ferronickel slag, silicon ash, the one or more of clinker, dispersant account for 1%, are lignosulfonates or naphthalene
Sulfonate and formaldehyde condensation product, crystallization derivant account for 25%~30%, are calcium carbonate superfine powder powder, and exciting agent accounts for 5%, be aluminium sulfate and
Its derivative, micro-expanding agent account for 4%, are the magnesia or calcium oxide of different degree of calcinations.
Described cement is common portland cement.
Compared with prior art, it is using the effect of the premixing fluidised form solidified earth of the technical program：
1. be advantageous to economize on resources, environmental protection.The solidified earth composition of the present invention is divided into water, soil, multi-functional compound material, cement,
Wherein soil comes from live earth work, can largely reduce the soil of roach occupancy, avoid after-treatment, realize reduction cost
Main purpose；Composite solid material is by levigate industrial waste and adds the functional materials of respective components and forms, thus of the invention
Solidified earth can largely consume accumulation at the construction field (site) around discarded soil, it is cost-effective.
2. the solidified earth of the present invention, the wherein main component of composite solid material are the Industry Wastes such as levigate clinker and flyash
Material, realizes effective utilization of industrial waste；With the premixing fluidised form solidified earth of the present invention in engineering, industry can be largely consumed
Waste material, resource is saved, cost is reduced, is advantageous to environmental protection, belong to low-carbon, green, environmentally friendly machine.
3. this solidified earth is better in piping lane backfill, the engineering characteristic required for piping lane backfill can be reached so that
The earthwork dug out during piping lane is built by adding water to stir, compactness increase, intensity is higher, later strength development potentiality is larger, anti-
Water stability is good.And in the prior art, the construction method such as concrete, sixteen dirt, plain soil, cost is high, and progress is slow, water stability
Difference, it is impossible to meet Engineering Control index.
