Description
Technical field
The present invention relates to the foundation pit dewatering equipment of civil works foundation construction, a kind of specifically vacuum foundation-pit deep-well precipitation apparatus.
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 in Foundation Pit Construction, satisfy the requirement of supporting and protection structure and excavation and construction with dewatering, the groundwater table of construction environment is high more, the degree of depth of foundation requirement is dark more, and its difficulty of construction is big more.For the variation that prevents the following peripheral, ground brings 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, deep-well chimney filter, submersible pump etc., its difficult point is that the difficulty that causes drawing water strengthens submersible pump dive difficulty along with the increase of the well depth degree of depth, disposable input is many, the running cost height, spillage of material is many, and result of use is undesirable.
Summary of the invention
A kind of vacuum foundation-pit deep-well precipitation apparatus of providing at the deficiencies in the prior art is provided, it has omitted submersible pump, do not having under the condition of submersible pump, vacuumize simultaneously, draw water and can increase substantially the degree of depth of drawing water with vacuum pump, the vacuum distributive pipe adopts flexible pipe, and dive is very convenient, reduced difficulty of construction, disposable input is little, and running cost is low, and result of use is good.
The object of the present invention is achieved like this:
A kind of vacuum foundation-pit deep-well precipitation apparatus, characteristics are 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 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 1 or several apertures.
The present invention is simple in structure, and submersible pump and auxiliary line have been saved in easy construction, and disposable input is little, and running cost is low, and result of use is good.
Description of drawings
Fig. 1 is a structural representation of the present invention
Fig. 2 is a user mode reference diagram of the present invention
The specific embodiment
Consult Fig. 1, the present invention includes 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 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 1 or several apertures 9.
Consult Fig. 2, when the present invention works, 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 2-5mm 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 1 or the about 2-5mm in several apertures on vacuum distributive pipe 5, and the position of aperture 9 is moved on progressively by about 1-4m place, deep-well chimney filter 2 bottoms, and the pitch-row observing water level is just decided.Water in the soil of well point is inhaled 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 by vacuum pump 1.Guarantee to have only on the water level of 1 aperture 9 deep-well chimney filter 2 on the vacuum distributive pipe 5, the aperture 9 of unnecessary emersion is sealed one by one, normally move with the assurance state that draws water.
The present invention can be provided with many groups well point and work simultaneously according to the watt level of vacuum pump, the degree of depth of well location.
