Background technology
At present, construction industry large-area soft ground consolidation process and excavation of foundation pit, all refer to lowering of watertable, with
Meet the requirement of reduction water content of soil.The method for reducing soil body level of ground water typically uses well-points dewatering, the side of tube well dewatering
Method is realized, in both techniques, and its tube well dewatering can reach below 20m due to insertion soil body depth, and be released by waterpower
The principle of weight, precipitation depth can reach below 10m, be that soft soil foundation deep layer precipitation creates condition, therefore tube well dewatering is
It is widely used in reinforced soft soil ground processing.
But in work progress is implemented, infiltration coefficient requires higher to tube well dewatering, that is to say that tube well dewatering is typically suitable
It is 20 ~ 200m/d soil layers in infiltration coefficient, to the less muck soil of infiltration coefficient, can not be just applicable.According to this difficult point, it is
The strong point and advantage of tube well dewatering are given full play to, vacuum tube well precipitation is generated, i.e., by being closed to pipe well mouthful, and accessed
Vavuum pump, carries out vacuum-dewatering.But, needing in the range of reinforcement depth, its soil property is not quite similar, soil layer infiltration coefficient is also not to the utmost
It is identical.When vacuum tube well is under conditions of vacuum-dewatering, most of negative pressure of vacuum is melt into the preferable soil layer of soil property, in actual measurement
During the vacuum pressure of vacuum tube well, it can not measure substantially.Its main cause is exactly that most or whole vacuum pressures disappear
Lose in the preferable soil layer of infiltration coefficient, and need in the mud of negative pressure of vacuum, then because muck soil can not obtain vacuum
Negative pressure.It is basic without negative pressure of vacuum in other words.Therefore, vacuum tube well precipitation is unsatisfactory to the effect of mud.

It is as follows using the soft foundation Yield rainfall relation method and step of air-cushion type batch vacuum pipe well：
Step 1: assembling air-cushion type batch vacuum pipe well
Step 2: injection pipe well：
3.1st, injection pipe well is constructed according to conventional job specfication；
3.2nd, according to immersible pump is put into after the completion of code requirement injection pipe well, trial operation under conditions of pipe well normal operation, enters
Enter next step；
Step 3: batch vacuum precipitation
It is determined that layering position：Data or the construction experience according to well-digging process are surveyed in base area, determine the poor soil layer of infiltration coefficient
Position, puts into airfilled ring, after airfilled ring reaches defined location in pipe well, airfilled ring is inflated, airfilled ring is stuck in
Required position；
Put into inner ring cover plate：After all pipelines are connected firmly on inspection, inner ring cover plate is put into airfilled ring and covered in airfilled ring
On, after inner ring cover plate is covered on airfilled ring, open gear outside the sliding block on inner ring cover plate, sliding block and open and be stuck on pipe well wall,
Complete after the installation of inner ring cover plate, connect vavuum pump, vacuumized.

Compared with prior art, the beneficial effects of the invention are as follows：
1st, implement simple, it is applied widely
Using traditional precipitation pipe well, the soil layer poor to infiltration coefficient is layered by setting air-cushion type in pipe well, forms one
The dual-purpose function of pipe, had not only been drawn water using gravity precipitation but also using vacuum, and had made to need precipitation region by different dewatering modes, reach
Soil moisture content is uniform, meets weak soil Yield rainfall relation needs.And air cushion layering can arbitrarily set its vacuum according to the different layers of soil property
Negative pressure occurrence scope, expands the scope of application of tube well dewatering, it is ensured that the dewatering effect of the different soil properties of different thickness.
2nd, the engineering time is short, and speed is fast, low cost
Of the invention to expand applicability of the tube well dewatering to soil property compared with existing traditional pipe well, traditional tube well dewatering is applied to
Soil layer infiltration coefficient is 20 ~ 200m/d, and 20m/d soil property is less than to infiltration coefficient, and particularly muck soil is absolutely void, mainly
Reason is that tube well dewatering is to release water by gravity.Pipe well is layered using air-cushion type, due to being less than 20m/d soil property to infiltration coefficient
By vacuum-dewatering, and by layering, negative pressure of vacuum concentrates on the soil property that infiltration coefficient is less than 20m/d, therefore its tube well dewatering
Effect substantially, force of gravity releases water precipitation speed faster.
The present invention is compared with vacuum tube well, because vacuum tube well precipitation is generally used for the soil property that infiltration coefficient is less than 20m/d,
In the range of required drawdown, soil property is not quite similar, and when local infiltration coefficient is larger, then thus substantial amounts of negative pressure of vacuum can let out
Leakage, causes vacuum tube well without vacuum situation, makes existing vacuum tube well and to no effect.And the present invention is divided by being set in pipe well
Layer, the soil property that 20m/d is more than to infiltration coefficient releases water using gravity（That is tube well dewatering）, 20m/d soil is less than to infiltration coefficient
Matter is isolated using layering, carries out negative pressure of vacuum precipitation.So as to ensure that vacuum tube well precipitation is only used for the small soil layer of infiltration coefficient,
So as to reduce precipitation time, Rain quality is improved.
3rd, it is environment friendly and pollution-free, construction site civilization
Air-cushion type is layered tube well dewatering, and designed layering dewatering device is reusable device, is inflated when using, not the used time
It is i.e. recyclable after deflation, it is that civilized construction creates conditions.
4th, deep layer precipitation, efficiency high
The air-cushion type vacuum tube well layering dewatering device of the present invention, can arbitrarily be adjusted according to pipe well embedded depth, unrestricted, special
Be not large-area precipitation construction in, can be different because of well to different soil residing for group wells, the scope different depth that buried to each well enters
The different setting of row, the particularly consolidation process to interlayer soil, its dewatering effect are more obvious.Its negative pressure of vacuum can pass through layering
The vacuum meter set on cover plate is shown, is easy to the supervision and management of work progress.Therefore, this method cannot be only used for civil engineering work
Journey, it may also be used for the consolidation process of road, place, underground piping etc..
Air-cushion type batch vacuum pipe well of the present invention and its construction method step are simple, by taking difference to different soil layers
Precipitation method, reached that a well is dual-purpose, can both meet the dewatering effect of different soil, again can to bad ground carry out multilayer it is true
Airborne water.Therefore different soil property Yield rainfall relation constructions are suitable for, solving existing tube well dewatering, vacuum tube well precipitation can not go beyond
Obstacle, which is lowering of watertable, reduce water content of soil lays a good foundation.
