Abstract
The utility model discloses a kind of reinforced soft soil ground to handle vacuum low-level prepressing device, including gully and the conduit being arranged in gully, the draining bottom is coated with filter membrane and stretches to soft soil foundation bottom, the gully is connected with vavuum pump and booster pump respectively, conversion valve is provided with the gully to be optionally connected with vavuum pump or booster pump, the conduit is provided with check valve, when soft soil foundation water level is higher, control conversion valve causes booster pump to be communicated with gully, discharged by being pressurized body of groundwater into gully through conduit, greatly reduce the water resistance in gully；In supercharging draining simultaneously, moreover it is possible to puncture the well resistance of draining well screen section, well inhibition effect can be effectively reduced so that the unimpeded draining of gully.
Description
Technical field
Reinforced soft soil ground field of engineering technology is the utility model is related to, more particularly to a kind of reinforced soft soil ground processing is true
Empty low-level prepressing device.
Background technology
For soft soil foundation, when carrying out processing reinforcing using the methods of vacuum preloading or piling prepressing, typically in weak soil
Vertical sand drain or plastic draining board are set in ground as drainage channel, is issued in heap material containing gravity load or vacuum load precompressed
Raw discharging consolidation, pore water pressure slowly dissipate, and effective stress slowly increases, and foundation strength gradually increases, ground consolidation sedimentation
The amount overwhelming majority is eliminated within the construction time, so that the bearing capacity of soft soil foundation is improved.
But there is following defect in the above method when carrying out highway on soft ground：One side mud particles are for a long time
Under osmosis, compacted zone can be formed in the vertical sand drain borehole wall, cause vertical drainage " well resistance " phenomenon；On the other hand, earth's surface is true
Reciprocal of duty cycle is transmitted acted on by water resistance downwards, and vacuum can not quickly be transferred to ground basal part undampedly, so as to influence to weak soil
The reinforcement effect and effect of base.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of reinforced soft soil ground processing vacuum low-level prepressing dress
Put.
Technical scheme used by solve above-mentioned technical problem：A kind of reinforced soft soil ground processing vacuum low-level prepressing dress
Put, including gully and the conduit that is arranged in gully, the draining bottom are coated with filter membrane and stretch to soft soil foundation
Bottom, the gully are connected with vavuum pump and booster pump respectively, and conversion valve is provided with the gully with selectivity
Ground is connected with vavuum pump or booster pump, and the conduit is provided with check valve.
Further, water level switch is provided with the gully.
Further, three-way pipe, described three-way pipe one end and vavuum pump and booster pump phase are connected with the top of the gully
Connection, the three-way pipe other end stretch out for conduit.
Beneficial effect：In this reinforced soft soil ground processing vacuum low-level prepressing device, when soft soil foundation water level is higher, control
Conversion valve processed causes booster pump to be communicated with gully, is outwards arranged through conduit by being pressurized body of groundwater into gully
Go out, greatly reduce the water resistance in gully；In supercharging draining simultaneously, moreover it is possible to puncture the well resistance of draining well screen section, can be effective
Ground reduces well inhibition effect so that the unimpeded draining of gully.By the utility model low-level prepressing device, water can be effectively reduced
Resistance, well inhibition effect are to the adverse effect of discharging consolidation, the drainage channel blind area of elimination traditional vacuum precompressed.
Brief description of the drawings
The utility model is described further with reference to the accompanying drawings and examples；
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Reference picture 1, a kind of highway on soft ground vacuum prepressing device of the utility model, including gully 1 and the row of being arranged on
Conduit 2 in well 1, conduit 2 select pvc pipe, and the bottom of gully 1 stretches to soft soil foundation bottom and is coated with filter membrane in bottom
3, the top of gully 1 is connected with three-way pipe, and one end mouth of pipe of the top of conduit 2 through three-way pipe is protruding, and enters at the mouth of pipe
Row encapsulation process, the other end mouth of pipe of three-way pipe are connected with vavuum pump and booster pump respectively（It is not drawn into）, gully 1 and vacuum
Pump, the junction of booster pump are provided with conversion valve（It is not drawn into）, by conversion valve gully 1 and vavuum pump can be controlled independent
Connection or gully 1 individually connect with booster pump, wherein, water level switch is provided with the gully 1, when water level is higher, is controlled
Conversion valve is connected with booster pump, carries out supercharging draining, and when water level is relatively low, control conversion valve is connected with vavuum pump,
Normally vacuum preloading is carried out to load.
Specifically, when being pressurized draining, booster pump is pressurized into gully so that body of groundwater discharges through conduit 2, greatly
The big water resistance reduced in gully；In supercharging draining simultaneously, moreover it is possible to the soil formed in back draught impact draining well screen section
Body compacted zone, that is, well resistance is broken up, gully inhibition effect can be effectively reduced so that the unimpeded draining of gully.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Embodiment is stated, in the technical field those of ordinary skill possessed knowledge, this practicality can also not departed from
Various changes can be made on the premise of new objective.
