Abstract
The utility model discloses special equipment for the well-point dewatering of a deep well in a basic pit, which comprises a vacuum pump, a deep well filter tube, a cover of the filter tube, a vacuum water main, a vacuum water-dividing tube and a water drainage tube, wherein the cover of the filter tube is arranged on the top part of the deep well filter tube and is hermetically connected with the deep well filter tube, and small holes are uniformly distributed on a tube body of the deep well filter tube. The water drainage pipe and the vacuum water main are respectively connected with both ends of the vacuum pump. The vacuum water-dividing tube is connected with the vacuum water main, and is extended in the deep well filter tube by the cover of the filter tube. The small holes are arranged on the cover of the filter tube and on the water-dividing tube. The utility model has the advantages of simple structure, convenient use, small disposable investment and low operation cost, and a diving pump and an auxiliary pipeline are saved.
Description
Technical field
The utility model relates to deep foundation pit precipitation equipment, particularly a kind of foundation-pit deep-well well-points dewatering special equipment.
Background technology
Deep pit digging is the important construction sequence of modern large underground structure, dewatering also claims groundwater control in the foundation ditch, promptly underground water will satisfy the requirement of supporting and protection structure and excavation and construction in Foundation Pit Construction, and the variation because of the following peripheral, ground does not bring harm to environment and facility around the foundation ditch, therefore the general mode of deep-well well point dewatering that adopts solves this type of technical problem and uses special equipment, deep-well well-points dewatering equipment of the prior art comprises vacuum pump, the deep-well chimney filter, submersible pump etc., its shortcoming is disposable having high input, the running cost height, spillage of material is many, and result of use is undesirable.
Summary of the invention
The purpose of this utility model is a kind of foundation-pit deep-well well-points dewatering special equipment that provides at the deficiencies in the prior art, and it has saved submersible pump, and disposable input is little, and running cost is low, and result of use is good.
The purpose of this utility model is achieved in that
A kind of foundation-pit deep-well well-points dewatering special equipment, it is characterized in that it comprises vacuum pump, deep-well chimney filter, chimney filter lid, vacuum water main, vacuum distributive pipe, gutter, the chimney filter lid is located at deep-well chimney filter top and is tightly connected with it, deep-well chimney filter part pipe shaft is laid with aperture, gutter, vacuum water main are connected to the vacuum pump two ends, the vacuum distributive pipe is connected with the vacuum water main and stretches in the deep-well chimney filter by the chimney filter lid, and chimney filter covers and is provided with aperture, and the vacuum distributive pipe is provided with aperture.
The utility model is simple in structure, and is easy to use, saved submersible pump and auxiliary line, and disposable input is little, and running cost is low, and result of use is good.

The specific embodiment
Consult Fig. 1, the utility model comprises vacuum pump 1, deep-well chimney filter 2, chimney filter lid 3, vacuum water main 4, vacuum distributive pipe 5, gutter 6, chimney filter lid 3 is located at deep-well chimney filter 2 tops and is tightly connected with it, deep-well chimney filter 2 part pipe shafts are laid with aperture 7, gutter 6, vacuum water main 4 are connected to vacuum pump 1 two ends, vacuum distributive pipe 5 is connected with vacuum water main 4 and stretches in the deep-well chimney filter 2 by chimney filter lid 3, and chimney filter lid 3 is provided with aperture 8, and vacuum distributive pipe 5 is provided with aperture 9.
Consult Fig. 2, during the utility model work, deep-well chimney filter 2 is buried in the well point, chimney filter lid 3 elevates above the soil, have the aperture 8 of the about 3-5mm in an aperture on the chimney filter lid 3, vacuum distributive pipe 5 stretches in the deep-well chimney filter 2 by filter well lid 3 and have the aperture 9 of the about 3-5mm in an aperture on vacuum distributive pipe 5, and preferably open about the distance deep-well chimney filter about 1-4m in 2 bottoms the position of aperture 9.Water in the soil of well point enters in the deep-well chimney filter 2 by the uniform aperture 7 of deep-well chimney filter 2 pipe shafts, starts vacuum pump 1, and the water in the deep-well chimney filter 2 enters vacuum water main 4 from vacuum distributive pipe 5, flows out from outlet pipe 6 again.Aperture 9 on the vacuum distributive pipe 5 should remain in the deep-well chimney filter 2 and could normally move by assurance equipment on the water level.
The utility model can be provided with many groups well point and work simultaneously according to the watt level of vacuum pump.
