Description
Technical field
The utility model is related to the improved technology of the assisted drainage equipment in deep pit construction, especially deep basal pit pipe
Well precipitation apparatus.
Background technology
Deep pit digging is that lowering of watertable is also in the important operational procedure of modern heavy construction underground structure, foundation ditch
Claim Groundwater Control, i.e., meet the requirement of building enclosure and excavation and construction with lowering of watertable in Foundation Pit Construction,
The level of ground water of construction environment is higher, and the depth of foundation requirement is deeper, and its difficulty of construction is bigger.To prevent the change of ground following peripheral
Harm is brought to the environment and facility around foundation ditch, thus it is general using the implementation deep well points lowering of watertable solution of drainage well
Such technical problem base pit dewatering refers to that in underground engineering construction pit earthwork needs to carry out precipitation to the soil body before excavating,
Underground water absolute altitude is down to below excavation of foundation pit face, reaches the requirement of the anhydrous excavation of foundation ditch.
At present, deep foundation pit precipitation engineering carries out precipitation mainly using vacuum-dewatering pipe well construction using vavuum pump.Vacuum tube
Well precipitation system is made up of vavuum pump, immersible pump, pumping and draw water pipeline, wellhead sealing system and well casing.The well of vacuum tube well
Pipe uses sand-free concrete tube or steel pipe；Wellhead sealing uses flange+sealing gasket, lower flange and steel-pipe welding and with dead Guan Lian
Connect, each junction carries out encapsulation process；According to formation condition and requirement of engineering any well section carry out segmented seal processing with
Layering precipitation is realized, segmented seal is using dead pipe and the processing of clay ball；Vavuum pump uses water-ring vacuum pump, single pump connection 3
~4 mouthfuls of wells, the larger vavuum pump connection pipe well reasonable quantity increase of pump amount.The arrangement spacing of vacuum tube well is generally higher than 10m.Very
Airborne water pipe manhole construction creates vacuum condition by being evacuated, and installs complicated, and the sealing requirements to pipe well are high；Needed in Precipitation Process
There is special messenger's nurse, manufacturability requires higher；There is easy plugging in mud suction line；The buying of vacuum-dewatering pipe well, operation, maintenance
Cost is higher.
Utility model content
The purpose of this utility model is to provide deep basal pit tube well dewatering equipment, reduces precipitation apparatus installation difficulty, saves into
This, solves prior art problem.
The purpose of this utility model will be realized by following technical measures：Including air compressor machine, ejection water pipe, drainpipe and
Air inlet pipe；Air inlet pipe is vertically-mounted parallel with drainpipe, air compressor machine connection air inlet pipe upper end, air inlet pipe lower end access drainpipe bottom
In end, drainpipe upper end connection ejection water pipe.
Especially, air inlet pipe is passed and is fixed on well lid with drainpipe upper end；On the upside of well lid, drainpipe upper end passes through
T-joint connection ejection water pipe, t-joint is also connected with spare exhaust pipe simultaneously, and spare exhaust pipe is passed down through after well lid and opened
Mouth is on the downside of well lid.Meanwhile, unidirectional gas check valve is installed on spare exhaust pipe.
Especially, drainpipe lower end tube wall connection counterweight.
Advantage and effect of the present utility model：It is quick for installation, external environment condition strong adaptability；Reduce pipe well air-proof condition, fortune
Row is easy to maintenance, and expense is low.Equipment is voluntarily operated, without special messenger's nurse；Energy-saving, safe and environment-friendly, precipitation cost is low, dewatering effect
Good advantage.

Embodiment
The utility model is applied to dig the deep deep-foundation pit engineering precipitation for exceeding 5m.
The utility model includes：Air compressor machine 1, ejection water pipe 3, drainpipe 7 and air inlet pipe 8.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment 1：As shown in Figure 1, air inlet pipe 8 and drainpipe 7 are parallel vertically-mounted, in the connection air inlet pipe 8 of air compressor machine 1
In end, the lower end of air inlet pipe 8 access drainpipe 7 bottom, the upper end of drainpipe 7 connection ejection water pipe 3.
In foregoing, air inlet pipe 8 is passed and is fixed on well lid 5 with the upper end of drainpipe 7；On the upside of well lid 5, drainpipe 7
End is also connected with spare exhaust pipe 4 simultaneously by the connection ejection water pipe 3 of t-joint 2, t-joint 2, and spare exhaust pipe 4 is worn downwards
The after-opening of well lid 5 is crossed in the downside of well lid 5.Meanwhile, unidirectional gas check valve is installed on spare exhaust pipe 4.
In foregoing, the lower end tube wall connection counterweight 13 of drainpipe 7.
In the present embodiment, air compressor machine 1 is air compressor, the internal diameter 8mm of air inlet pipe 8, the internal diameter 25mm of drainpipe 7, air compressor machine 1
It is connected with air inlet pipe 8 by specialized barrel, air inlet pipe 8, drainpipe 7 are connected with well lid 5 by t-joint 2, air inlet pipe 8, row
Water pipe 7 is sealed by adhesive tape.
Operationally, air inlet pipe 8 is placed in well casing 10 the utility model embodiment with drainpipe 7, the upper end of well casing 10 dew
Go out earth's surface and be capped well lid 5, layer 6 is tamped on the outside of the external wall of upper portion of well casing 10 for clay, in the well casing 10 that clay tamps below layer 6
Portion's outer exterior wall installs chimney filter 11 in the lower end of well casing 10 to fill out gravel 9, and sand sediment pipe 14 is installed in the lower end of chimney filter 11, and the inner side of chimney filter 11 is pacified
Filter screen 12 is filled, the lower end of drainpipe 7 is arranged on the inner side of filter screen 12.
In the utility model, it is the compressed air using air compressor machine 1, is delivered to by air inlet pipe 8 in drainpipe 7, high pressure
Gas is mixed with water in pipe, and a kind of air-water mixture is formed in drainpipe 7, and negative pressure is formed in the bottom of drainpipe 7, and water below exists
Rise in the presence of negative pressure, and under the synergy of air pressure momentum, underground water constantly enters in drainpipe 7, forms steam and mixes
Continue to rise after compound, so that flowing is formed, because the interior basal area of drainpipe 7 is significantly smaller than the outer wall of drainpipe 7 and well casing 10
Between ring-type basal area, just form the great drainage channel of flow velocity, flow, by underground water discharge well casing 10.
