Description
Technical field
This utility model relates to a kind of pressure-bearing plugging dewatering well device, belongs to the internal antiseep field of basement deep basal pit.
Background technology
Deep foundation pit precipitation is that a bigger difficult problem, particularly foundation ditch width are relatively big, and level of ground water is higher, and water content is bigger
Engineering.
What employing was more at present is at surrounding deep foundation pit layout dewatering well, reduction foundation ditch level of ground water, but big for area,
Span big foundation ditch middle part dewatering effect is poor, does not reaches construction requirement, in order to reach dewatering effect, and simple intensification periphery precipitation
Well depth, certainly will strengthen dewatering project expense, Ground Settlement of Deep Foundation Pit may be caused to increase simultaneously, society is caused significant impact.
If suitably arranging drainage dewatering well in the middle of foundation ditch, then can well reach precipitation drainage effect, but in base plate, construct fall
The closure of well is again a big technical barrier, and after conventional steel closure, long-term corrosion easily produces seepage, it would be highly desirable to improve.
Utility model content
This utility model aims to provide a kind of pressure-bearing plugging dewatering well device, and this plugging device stagnant water effect is good, it is to avoid
Seepage occurs.
To achieve these goals, this utility model be the technical scheme is that
A kind of pressure-bearing plugging dewatering well device, including base plate, it is structurally characterized in that, is embedded with and dewatering well in described base plate
The sleeve pipe of well casing top docking, is fixed with lower floor's seal plate in described sleeve pipe, the top of this sleeve pipe is fixed with upper strata seal plate；Institute
State on lower floor's seal plate equipped with closure element.
This utility model realizes upper and lower two-layer seal plate by closure element and blocks, and sealing isolation effect is good, effectively prevents
Stop base plate leakage.
According to embodiment of the present utility model, it is also possible to make this utility model further to optimize, after being below optimization
The technical scheme formed:
In order to improve water seepage prevention effect further, between lower floor's seal plate and upper strata seal plate, it is filled with middle level closure
Layer.The most described middle level plugged zone is cement.
In order to facilitate fixing between lower floor's seal plate and sleeve pipe further, described closure element is for having sealing silk mouth
Closure element, this closure element is threaded on lower floor's seal plate.Thus, when fixing lower floor seal plate is with sleeve pipe, water pump
Can be pulled water out by the silk oral pore of closure element.
In order to realize minor diameter plugging effect, the diameter of described closure element is less than the half of casing diameter.
Preferably, the top end face of described sleeve pipe is positioned at below the upper surface of base plate 30mm-50mm.
In order to prevent tube displacement, described cannula tip is fixedly linked with the embedded bar in base plate by pressure pipe reinforcing bar.
By said structure, this utility model utilizes the occlusion closely of seal ring sleeve pipe and concrete to extend infiltration path,
Lower floor's seal plate and the fixing sealing that tentatively blocks of sleeve pipe, small-bore outlet silk mouth closure element carries out inspection for leakage, middle level
The fixing closure of anti-corrosion isolation, upper strata seal plate and the sleeve pipe of leak stopping cement is fixed and ensures.
Compared with prior art, the beneficial effects of the utility model are: this utility model is long after solving conventional steel closure
Phase corrosion produces the harm of seepage, has simple in construction, the advantages such as operation is convenient, cheap.

Detailed description of the invention
Below with reference to accompanying drawing and describe this utility model in detail in conjunction with the embodiments.It should be noted that do not conflicting
In the case of, the embodiment in this utility model and the feature in embodiment can be mutually combined.For sake of convenience, the most such as
Occur " on ", D score, "left", "right" printed words, only represent consistent, not to structure with the direction, upper and lower, left and right of accompanying drawing itself
Play restriction effect.
The internal pressure-bearing plugging dewatering well device of a kind of basement deep basal pit, mainly by steel thimble 1, lower floor's seal plate 2, middle level
The closure composition such as cement 3, upper strata seal plate 4.This utility model lower floor's seal plate 2 welding closure, middle level closure cement 3 are isolated
Welding the measures such as closure with upper strata seal plate 4, stagnant water effect is good, Seepage does not occurs.
This utility model solves the internal plugging dewatering well technical barrier of basement common in construction, has technique letter
Single, the advantages such as operation is convenient, cheap.It is applicable to all of deep foundation pit construction, can fit according to the surface area of foundation ditch, form
Preferably arrange multiple.
During construction, first in precipitation well in foundation pit position by dewatering well well casing by correct position, with making band seal ring
Steel thimble 1 connect, steel thimble 1 than base plate 5 reduce by 30 ~ 50mm；When base plate 5 concrete is constructed in order to prevent displacement, by steel bushing
The most fixing reinforcing bar of pipe 1 is firm with base plate 5 bar connecting, and the flexible material parcel protection of provided pipe top, base plate 5 has poured
After, chisel provided pipe periphery concrete with chisel gently, expose parcel protective material, clean out.After changing precipitation water pump, while take out
Waterside carries out the welding of lower floor's steel plate for sealing water, after having welded, extracts precipitation water pump pump line out, tightens with cap for filament port immediately and draw water carefully
Pipe, carries out pressure-bearing detection, if weld seam or silk mouth occur that seepage shows weld seam or silk mouth imprecision, needs to carry out at repair welding and silk mouth
Reason, such as ne-leakage water phenomenon, carries out middle part isolation grout off after observing 24h, after having blocked, and construction upper strata Plate Welding,
Guarantee that weld seam is firm tightly, after Plate Welding completes, sleeve pipe 1 is pushed down in base plate 5 gluten overlap welding.Finally by the construction joint of periphery
Clean out, get final product local, teeming dewatering well sleeve pipe 1 position concrete, strengthen maintenance 7 days.
The content that above-described embodiment illustrates should be understood to that these embodiments are only used for being illustrated more clearly that this utility model,
Rather than limit scope of the present utility model, after having read this utility model, those skilled in the art are new to this practicality
The amendment of the various equivalent form of values of type each falls within the application claims limited range.
