Description
Technical field
It the utility model is related to a kind of air-cushion type batch vacuum pipe well and apply its soft foundation Yield rainfall relation method.For
The quick lowering of watertable of soft soil foundation, construction cost can be reduced by this method, reduce labor intensity, improve efficiency of construction.
Possession base processing technology field.
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 for reducing water content of soil.The method of soil body level of ground water is reduced typically using well-points dewatering, the side of tube well dewatering
Method is realized, in both techniques, its tube well dewatering is released because insertion soil body depth can reach below 20m by waterpower
The principle of weight, precipitation depth can reach below 10m, create condition for soft soil foundation deep layer precipitation, 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, generates vacuum tube well precipitation, i.e., by being closed to pipe well mouth, and is accessed
Vavuum pump, carry out vacuum-dewatering.But needing in the range of reinforcement depth, its soil property is not quite similar, and 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, is surveying
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.In other words at all without negative pressure of vacuum.Therefore, vacuum tube well precipitation is unsatisfactory to the effect of mud.
The content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of that can different soil properties be carried out with different precipitation
Construction, can reach a bite pipe well can carry out tube well dewatering, and and can meets that the air-cushion type layering of this double action of vacuum-dewatering is true
Blank pipe well.
What the purpose of this utility model was realized in：
A kind of air-cushion type batch vacuum pipe well, it includes pipe well, air-cushion type vacuum tube well is provided with the middle part of the pipe well
Dewatering device is layered, air-cushion type vacuum tube well layering dewatering device includes the airfilled ring of inner ring cover plate and quality of rubber materials, described interior
Four slideways of right-angled intersection arrangement are provided with ring cover plate, one slide-plate is provided with each slideway, is set on inner ring cover plate
It is upward to put vavuum pump adapter hole, vacuum meter adapter hole, cable and suspending pump cord hole and drain tube holes, its intermediate pump adapter hole
Connect vacuum generator tube, vacuum meter adapter hole connects up vacuum meter pipe, cable and suspending pump cord hole connect up cable and
Suspending pump rope pipe, drain tube holes connect downwards drainage connecting pipe, and drain tube holes connect up drainpipe, downward in interior ring cover plate both sides
Tapping pipe is provided with, the airfilled ring is arranged at below inner ring cover plate, and the airfilled ring external diameter is slightly larger than the internal diameter of pipe well.
Compared with prior art, the beneficial effects of the utility model are：
1st, implement simply, it is applied widely
Using traditional precipitation pipe well, the soil layer poor to infiltration coefficient, by setting air-cushion type to be layered in pipe well, shape
Function dual-purpose Cheng Yiguan, not only drawn water using gravity precipitation but also using vacuum, and made to need precipitation region by different dewatering modes,
It is uniform to reach soil moisture content, meets weak soil Yield rainfall relation needs.And air cushion layering can arbitrarily set it according to the different layers of soil property
Negative pressure of vacuum occurrence scope, the scope of application of tube well dewatering is expanded, ensure that the dewatering effect of different thickness difference soil properties.
2nd, the engineering time is short, and speed is fast, and cost is low
The utility model expands applicability of the tube well dewatering to soil property, traditional pipe well drop compared with existing traditional pipe well
Water is 20 ~ 200m/d suitable for soil layer infiltration coefficient, and 20m/d soil property is less than to infiltration coefficient, and particularly muck soil is basic
Invalid, main cause is that tube well dewatering is to release water by gravity.Pipe well is layered using air-cushion type, due to being less than to infiltration coefficient
20m/d soil property is by vacuum-dewatering, and by layering, and negative pressure of vacuum concentrates on the soil property that infiltration coefficient is less than 20m/d, therefore
The positive effect of its tube well dewatering, force of gravity release water precipitation speed faster.
The utility model is compared with vacuum tube well, because vacuum tube well precipitation is generally used for infiltration coefficient less than 20m/d's
Soil property, in the range of required drawdown, soil property is not quite similar, and when local infiltration coefficient is larger, then substantial amounts of negative pressure of vacuum can be by
This leakage, causes vacuum tube well without vacuum situation, makes existing vacuum tube well and to no effect.And the utility model passes through in pipe well
Layering is set, water is released using gravity to soil property of the infiltration coefficient more than 20m/d（That is tube well dewatering）, 20m/ is less than to infiltration coefficient
D soil property is isolated using layering, carries out negative pressure of vacuum precipitation.So as to ensure that it is small that vacuum tube well precipitation is only used for infiltration coefficient
Soil layer, so as to reduce precipitation time, improve Rain quality.
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, inflates during use, no
It is i.e. recyclable after used time deflation, created conditions for civilized construction.
4th, deep layer precipitation, efficiency high
Air-cushion type vacuum tube well of the present utility model is layered dewatering device, can arbitrarily be adjusted according to pipe well embedded depth, no
It is restricted,, can be different because of well to different soil residing for group wells particularly in large-area precipitation construction, scope of being buried to each well
Different depth carries out different settings, and the particularly consolidation process to interlayer soil, its dewatering effect is more obvious.Its negative pressure of vacuum
The vacuum meter that can be set by being layered on cover plate is shown, is easy to the supervision and management of work progress.Therefore, this method not only can use
In civil engineering, it may also be used for the consolidation process of road, place, underground piping etc..
The utility model air-cushion type batch vacuum pipe well and its construction method step are simple, by taking different soil layers
Different precipitation methods, has reached that a well is dual-purpose, can both meet the dewatering effect of different soil, and and can carries out more to bad ground
Layer vacuum-dewatering.Therefore different soil property Yield rainfall relation constructions are suitable for, solve existing tube well dewatering, vacuum tube well precipitation can not exceed
Obstacle more, laid a good foundation for lowering of watertable, reduction water content of soil.
