Abstract
The utility model discloses a kind of ultra-deep foundation pit dewatering well shut-in well structure, the bottom plate including well head is arranged in, the upper port positioned at the downcast well pipe of bottom plate is flushed with plate upper surface；Cover board is fixed with by chemistry collided gudgeon on the bottom plate；Water expandable waterstop is provided on the bottom plate.The utility model construction procedure is simple, can save a large amount of process, and can avoid percolating water caused by artificial fault.It can be used for the close measure of various underground pipe well percolating waters, there is very high social benefit.
Description
Technical field
The present invention relates to deep basal pit Groundwater Control field, specially a kind of ultra-deep foundation pit precipitation shut-in well structure.
Background technique
With the development of society, especially scientific and technical progress, is greatly facilitated the rapid development of social productive forces；People
Material life and cultural life be greatly improved and improve；The especially rapid development of urbanization process, so that
Many advantage social resources high concentration on limited soil, such as the dense distribution of institution of higher learning；So that talented people
Just swarm forward to these cities；The basic clothing, food, lodging and transportion -- basic necessities of life of people and groundwork in city in order to meet denser population；Just
Need development that building downwardly and upwardly deepens continuously；Many building are rised sheer from level ground like the mushrooms after rain.
In recent years, the development utilized with the underground space, China's deep-foundation pit engineering are increasing.Deep-foundation pit engineering percolating water
Accident happens occasionally, part of accident be because dewatering well shut-in well improper measures and caused by.It shunts in a well in previous dewatering well
In measure, guide-well is first often covered into outside weld twice seal ring, draws water, play pump, then investment siccative, welding well lid are last in well
High grade slightly expanded concrete, complicated construction technique are poured, and process is compact, processing quality is more demanding when welding well lid.It is super
Deep basal pit underground water hydraulic pressure is larger, will appear prominent emerge in large numbers as and human factor leads to well when concrete fills dewatering well not in time
Lid welding quality is unqualified, effectively underground water cannot be prevented to leak.
Therefore, how effectively, quickly, easily block dewatering well, guarantee that underground water will not leak and influence next step work
Sequence construction is the key that prevention and treatment deep basal pit percolating water.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the present invention provides one kind to be suitable for ultra-deep foundation pit dewatering well
The shut-in well structure of percolating water after shut-in well, prevention shut-in well.
The object of the present invention is achieved like this:
A kind of ultra-deep foundation pit precipitation is shunt in a well structure, the bottom plate 1 including well head is arranged in, positioned at the downcast well pipe 2 of bottom plate 1
Upper port is flushed with 1 upper surface of bottom plate；Cover board 6 is fixed with by chemistry collided gudgeon on the bottom plate 1；The bottom plate 1
On be provided with water expandable waterstop 3；
Lid panel notches 4 are provided among the bottom plate 1；The cover board 6 is fixed in lid panel notches 4；
Shape, a body for water expandable waterstop 3 are embedded in lid panel notches to the water expandable waterstop 3 mostly in a ring
On bottom plate 1 in 4.
Positive beneficial effect: the utility model is completely enclosed with pure material formula at the top of dewatering well to guarantee, can be effective
Prevent underground water along leaktightness of wall of tubes, the utility model can have the ultra-deep base of leakage in particular for dewatering well with submersible
Hole.
Detailed description of the invention:
Fig. 1 is water expandable waterstop scheme of installation；
Fig. 2 is that cover board is installed rear elevation；
Fig. 3 is that cover board is installed back plan view.
In figure are as follows: bottom plate 1, downcast well pipe 2, water expandable waterstop 3, lid panel notches 4, chemically expansible bolt 5, cover board 6.
And lid panel notches 4, M12 chemically expansible bolt 5.
Specific embodiment
With reference to the accompanying drawing and specific embodiment, the present invention is described further:
The structure as shown in Figure 1-3, a kind of ultra-deep foundation pit precipitation is shunt in a well, the bottom plate 1 including well head is arranged in are located at bottom plate 1
The upper port of downcast well pipe 2 flushed with 1 upper surface of bottom plate；Cover board is fixed with by chemistry collided gudgeon on the bottom plate 1
6；Water expandable waterstop 3 is provided on the bottom plate 1；
Lid panel notches 4 are provided among the bottom plate 1；The cover board 6 is fixed in lid panel notches 4；
Shape, a body for water expandable waterstop 3 are embedded in lid panel notches to the water expandable waterstop 3 mostly in a ring
On bottom plate 1 in 4.
Embodiment
1, precipitation Well Water Level, guaranteed water level 500 ㎜-below the absolute altitude of Foundation Pit bottom before dewatering well cutting are measured in advance
1000㎜；
2,20*30 ㎜ water expandable waterstop can be accommodated by reserving twice along dewatering well outer wall of steel pipe when sole plate pours
Water expandable waterstop is embedded in 1/2 slot, then receives face by 1/2 slot；As shown in Figure 1；
2.1 receive the low raft plate in face top 10mm lid panel notches 5 along 500 ㎝ range inner concrete of dewatering well outer wall；
The qualified water expandable waterstop of the 2.2 regular producers of selection, service life at 30 years or more, seep by such as discovery failure
Water can be replaced at any time.
3, concrete curing 14 days, carry out within the scope of 450 ㎜ of dewatering well border chemically expansible bolt base material drilling setting-out (
Every 10 ㎝), drilling, borehole cleaning are put into medicament, insertion screw, hardening health;
3.1 selection chemically expansible bolts
| Product specification | Screw rod model | Destroy pulling force |
| M12 | M12*160mm | 43.8KN |
4, the cutting of dewatering well steel pipe is concordant with concrete face herein, stops precipitation, plays pump;
5, installation diameter 1000mm*10 ㎜ steel plate group completes construction, as shown in Figure 2 as in cover board 6 to lid panel notches 4；
5.1 cover board, 6 pre-production checks that bore diameter, quantity can be installed in time after playing pump.
The utility model is completely enclosed with pure material formula at the top of dewatering well as guarantee, can effectively prevent underground water along pipe
Wall leakage, the utility model can have the ultra-deep foundation pit of leakage in particular for dewatering well with submersible.
Above embodiments are merely to illustrate preferred embodiments of the present invention, but the utility model be not limited to it is above-mentioned
