Compared with prior art, the beneficial effects of the utility model are mainly reflected in：By in pile tube and drain pipeline structure
Air extracted out by evacuator, form pressure difference, moisture in weak soil is penetrated into by the hole on pile tube, and enter draining and lead to
Road, is extracted out by evacuator, makes soft soil foundation uniform-compression, in the case where not producing soil deformation, is reinforced.With
Pore pressure in the growth of time, soil is gradually reduced, and the pore pressure of reduction is changed into the effective stress in soil, and vacuum is higher, edge
Depth attenuation is smaller, then increased effective stress is bigger, and consolidation effect is better.Equipment is simple, and constructional difficulties are less, the scope of application
Extensively.
Further, air-locked diaphragm seal is laid on soft soil foundation, strict covering can preferably make the water in weak soil
Point penetrate into pile tube in, be not in ground water and air enter weak soil in, reduce the pressure difference inside and outside pile tube, the water in ground
It can not all discharge, cause the consolidation effect of soft soil foundation poor.
Brief description of the drawings
Fig. 1 is the structural representation of the pile tube device of reinforcing soft ground of the present utility model.
Embodiment
As shown in figure 1, the utility model proposes a kind of pile tube device of reinforcing soft ground, including it is concrete prefabricated
Pile tube 1, sealing device 2, drain pipeline structure 3 and evacuator 4；The pile tube 1 is cavity structure, and the two of the pile tube 1
End is respectively openend 11 and sealing end 12；The openend 11 is provided with sealing device 2, and the sealing end 12 is enclosed construction；
The side wall of the pile tube 1 is provided with ventilative and pervious function the hole 13 of several bands；The drain pipeline structure 3 includes the mouth of pipe 31
With multiple pumping conduits 32, an evacuator 4 is provided with the mouth of pipe 31, the free end of the pumping conduit 32 is through described close
Seal apparatus 2 is inserted in the cavity of the pile tube 1.
Further, in the utility model, its preferred scheme is：The sealing end 12 of the pile tube 1 is taper configurations, profit
It is pressed into pile tube 1 by pile driving equipment in soft soil foundation.(scheme not mark with permeable filter provided with that can breathe freely in the hole 13
Go out), it can effectively prevent other impurity such as silt from entering in the cavity of pile tube 1, level of the hole 13 along the side wall of pile tube 1
Direction is uniformly distributed, and is evenly arranged at a certain distance along the vertical direction of side wall.And the evacuator 4 can use vacuum
