Abstract
The present invention provides a kind of prominent gush of deep basal pit artesian water to depressurize control water-bound, including being in be opened in earth's surface wellhole below vertically, well casing is provided in wellhole, the middle and upper part and lower part of well casing are steel chimney filter, it is also filled with filtrate packet in the bottom of well casing, is additionally provided with drainage cushion block on the outside of the bottom opening of well casing, immersible pump is additionally provided in well casing, immersible pump includes drainpipe, and drainpipe extends to the top open part of well casing.The present invention is by the way of carrying out shallow-layer drain combination using the pressure reducing well pipe progress deep layer draining of double steel chimney filter forms up and down and Horizontal filter pipe, deep basal pit high pressure can be terminated in a short time, big yield artesian water is dashed forward and gushed, compared to conventional method, it is with obvious effects to control water, water quality is good, no silt particle is taken out of, and without water burst security risk again.
Description
Technical field：
The present invention relates to architectural engineering device fields, more particularly to deep basal pit artesian water is prominent gushes decompression control water-bound.
Background technology：
In deep-foundation pit engineering accident, since the artesian water prominent accident for gushing generation in bottom accounts for greatly, at Foundation Pit Pouring
It is big to manage difficulty, and deals with improperly and can cause serious consequence.
Invention content：
In order to solve the above technical problems, the present invention will adopt the following technical scheme that：
Deep basal pit artesian water is prominent to gush decompression control water-bound, including is in be opened in earth's surface wellhole below vertically, is set in wellhole
It is equipped with well casing, the middle and upper part and lower part of well casing are steel chimney filter, and filtrate packet is also filled in the bottom of well casing, and the bottom of well casing is opened
It is additionally provided with drainage cushion block on the outside of mouthful, immersible pump is additionally provided in well casing, immersible pump includes drainpipe, and drainpipe extends to well casing
Top open part.
Preferably, being additionally provided with Horizontal filter pipe on the outside of the middle and upper part of well casing, Horizontal filter pipe includes horizontal ends in L fonts
And vertical end, the vertical end of Horizontal filter pipe are located at side of the Horizontal filter pipe far from well casing, the vertical end of Horizontal filter pipe extends ground
Face is simultaneously connected there are one vacuum pump.
Preferably, the horizontal ends of Horizontal filter pipe are higher than the steel chimney filter positioned at well casing middle and upper part.
Preferably, well casing passes through soil layer and aquiclude, the bottom of well casing extends to confined aquifer.
Preferably, the boundary between the upper limb and confined aquifer and aquiclude of the steel chimney filter of well casing lower part
