Description
Technical field
The invention belongs to civil construction technical fields, and in particular to a kind of vacuum tube well precipitation system.
Background technique
When certain locations carry out construction, due to the loose either underground water of ground soil property is more, even if
Consolidation it is solid again, it is also not possible to guarantee that foundation strength reaches specified requirement, this this all seriously affected During Initial Stage Construction work
The progress of journey, and the safety and reliability of construction is had a serious impact, therefore geology reinforcing is carried out to certain geology,
It solves the problems, such as ground water drainage, is nowadays unusual stubborn problem present in many fields.
Summary of the invention
Mesh of the invention, which has, is to provide a kind of vacuum tube well precipitation system.The system can efficiently solve under ground
The influence of Groundwater base keeps ground soil property closely knit, increases the intensity of ground.
The technical solution adopted by the present invention: vacuum tube well precipitation system, including header tank, centrifugal pump, vacuum pump, catchment it is total
The surface level of certain depth and smooth foundation pit are managed and dug on ground, is moved towards in length and breadth in foundation pit soil property lower edge by identical
Away from the pipe well for drilling through display shape arrangement, a well-point pipe is fitted in each pipe well, the outer wall along well-point pipe is laid with suction hole,
Filled with the filter material layer that water penetration is strong between pipe well inner wall and well point pipe outer wall, fill out above the filter material layer in pipe well equipped with one
The argillic horizon for determining thickness is embedded with the interconnected latticed collection being made of transverse pipe and longitudinal pipe intersection in argillic horizon
Supply mains is the position of pipe well below the latticed intersection of water header, and the end of each transverse pipe and longitudinal pipe is equal
It is connected to the well-point pipe in pipe well, is equipped with a layer concrete layer in foundation pit upper surface, the nozzle of well-point pipe is exposed at concrete layer
Outside, water header passes through centrifugal pump respectively and vacuum pump is connected to header tank.
Further, the diameter of the well-point pipe is 800 millimeters, and distance of the well-point pipe bottom end apart from pipe well bottom is
500 millimeters.
Further, the well-point pipe is provided with the suction hole of the certain queueing discipline of spacing on along its length.
The present invention compared with prior art the beneficial effect is that: the present invention will be arranged by being laid with drainage pipeline networks under ground
After pipe network is connected to filter well, groundwater mining is fallen using pump, ensure that the tightness degree and intensity of ground soil property, after being
The safety of continuous construction provides reliable guarantee.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the longitudinal sectional drawing of pipe well part of the present invention.
Specific embodiment
7 precipitation system of vacuum tube well under as shown in Figure 1, including header tank 1, centrifugal pump 2, vacuum pump 3, water header 4
With the surface level and smooth foundation pit 6 for digging certain depth on ground 5, moved towards in length and breadth in 6 soil property lower edge of foundation pit by identical
Spacing drills through the pipe well 7 of array shape, and such as Fig. 2, a well-point pipe 8 is fitted in each pipe well 7, and the outer wall along well-point pipe 8 is laid
Have suction hole 9, filled with the strong filter material layer 10 of water penetration on the outside of the well-point pipe 8 of pipe well 7, filter material layer 10 can using coarse sand or
Rubble is filled out equipped with certain thickness argillic horizon 11 above the filter material layer 10 in pipe well 7, can prevent pipe well gas leakage in this way,
It is embedded with the interconnected latticed water header 4 being made of transverse pipe and longitudinal pipe intersection in argillic horizon 11, is catchmenting
It is the position of pipe well 7 below the latticed intersection of general pipeline 4, and the end of each transverse pipe and longitudinal pipe is and in pipe well 7
Well-point pipe 8 is connected to, and is equipped with a layer concrete layer 12 in 6 upper surface of foundation pit, and the nozzle of well-point pipe 8 is exposed at outside concrete layer 12,
Water header 4 is connected to by centrifugal pump 2 and vacuum pump 3 with header tank 1 respectively.The diameter of the well-point pipe 8 is 800 millimeters,
And distance of 8 bottom end of well-point pipe apart from 7 bottom of pipe well is 500 millimeters.The well-point pipe 8 is provided with spacing on along its length
The suction hole 9 of certain queueing discipline.
After adopting the structure of the invention, with the extraction of dampening, level of ground water is gradually decreased, and the soil body is compacted, in this way, both preventing
The only generation of quicksand phenomenon, and achieve the purpose that increase foundation strength.
