Description
Technical field
The present invention relates to stiffening basic ground field more particularly to the consolidation process fields of soft soil foundation, specifically
A kind of multifunction module formula soil body pressing formation device.
Background technology
Soil structures are usually to be mixed by solids, liquid water and air, and various material mixing ratios are different to be produced
The raw bearing capacity not waited is pressurized when exerting pressure more than soil body bearing capacity and generates sidesway and Compression Settlement, need to original state
The mixed structure ratio of the soil body carries out artificial change, is affixed by under the action of pressure outside so that in the soil body solids particles it
Between compactness improve, the adrainage material being arranged in the soil body changes the mixing of the soil body as the channel that liquid water and air is discharged
Structure makes solid contents that ratio be continuously improved, and to improve the compactness between solids particles, so that the soil body is obtained enhancing and adds
Gu improvement achievees the purpose that be pressurized again without will produce lateral soil movement and Compression Settlement when soil body bearing capacity is more than the when of exerting pressure,
To meet the requirement to soil body pressure-bearing.
Weak soil include mud, silt clay, mucky silt, become silted up knot sludge, riverway sludge, peat, cumulosol,
Table rare earth, surface dust etc. are that a kind of natural moisture content is big, compressibility is high, natural void ratio is more than or equal to 1, low thin of shearing strength
Grain soil.Common draining concretion method mainly has preloading and Vacuum-loading Pre-pressing Method.Preloading is in ground
Middle setting drainage channel and vertical drainage system drain span to reduce soil solidifying, and ground is under railway embankment load action
Discharging consolidation makes foundation bearing capacity improve, and settlement after construction reduces.Vacuum-loading Pre-pressing Method is on the basis of preloading
On, airtight layer is formed on load, is constantly drawn water by the normal time, is formed negative pressuren zone in ground, it is soft to make
Clay discharging consolidation achievees the purpose that improve bearing capacity, reduces sedimentation.Above-mentioned discharging consolidation method, construction period is very long, generally
It could be completed at six months to 1 year, thus construction cost is very high, efficiency is very low.
Above-mentioned draining concretion method is suitable only for large-area construction.Also, since the height of preloading is placed restrictions on, the soil body is held
Load requires high occasion that can not also be applicable in.

1）Referring to Fig.1 8, the multifunction module formula soil body pressing formation device 19 of the present invention is hung to construction area by loop wheel machine 18.
2）Referring to Fig.1 9, the dead weight of multifunction module formula soil body pressing formation device 19 imposes the soil body longitudinal static pressure
Power；Impact hammer 13 imposes the soil body longitudinal impact force；Vibrating device 15 makes device 19 generate vibration, and then imposes height to the soil body
The lateral pressure of frequency；Three of the above force action makes the soil body fully be squeezed in the soil body, the aqueous vapor in the soil body through reinforcing body 5,
Conduit pipe 203 on filter device 4 and convex body reaches vacuum collecting chamber 5, then is extracted out via drinking-water pipe 10.Pumping system uses
Two-way pattern includes a vacuum pump 7 and a preposition moisture trap 8 per road.The work of moisture trap 8 one of the first via
After the section time, when the moisture water isolated reaches setting water level, the vacuum pump 7 on the road is stopped, and moisture trap 8 carries out
Draining, the second tunnel still keeps work.Two-way alternately operating, sustainable pump drainage water.In this process, the air water in the soil body is by most
It is discharged to big degree, the compactness between solid particle is improved.Solenoid valve 19 controls vacuum pump 7 and moisture trap 8
It opens and closes.
3）With reference to Figure 20, multifunction module formula soil body pressing formation device 19 is sling.The processed soil body is in lateral shape
Soil structures 21 are molded at corresponding with pressing formation modular shape, it is corresponding with 17 shape of vertical pile body being longitudinally formed
Vertical stake holes 29.Reinforcing body 6 remains in the soil body, can bear tension, resistance to compression, shearing resistance effect, to improve foundation bearing capacity, subtracts
Few sedimentation and the stability for increasing the soil body.Meanwhile the reinforcing body 6 can also continue to drain.
4）With reference to Figure 21, filler 23 is backfilled in molding pit 22 and vertical stake holes 29.It can once fill up, Huo Zhe
It is tamped again after filling up.One layer can also be filled out, is tamped, then fill out last layer, then tamp, until filling up.
5）With reference to Figure 22, multifunction module formula soil body pressing formation device 19 is hung to next construction area with loop wheel machine 18
Domain repeats step 2）-4）, until all construction areas all handle completion.
Wherein, step 4）Backfill filler can be with step 5）Progress can be synchronized to the operation in next region.
It is to be understood that：Above-described embodiment is the description of the invention, rather than limiting the invention, any
Without departing from the innovation and creation within the scope of true spirit, each fall within protection scope of the present invention.
