Abstract
The utility model provides a radial precipitation structure includes shaft, collector pipe, shaft supporting seat, backwater layer, water barrier, pipeline bottom plate and water -bearing stratum at least, the collector pipe sets up in the water -bearing stratum at shaft place, the pipeline bottom plate is located the water -bearing stratum upper end, the water barrier sets up in backwater layer bottom, the shaft supporting seat is fixed to be set up in the shaft bottom, the shaft supporting seat is located the water -bearing stratum bottom, reduce the ground water level of similar engineering with radial precipitation technique, solved this difficult problem fabulously. In addition, radial precipitation is applicable to all kinds of stratum, and its well depth and drawdown are unrestricted, though to there is the site condition also can solve with the engineering that conventional precipitation method can't the dry out in the municipal works betterly.
Description
Technical field
This utility model relates to a kind of well Precipitation Structure, especially a kind of radial well dewatering structure.
Background technology
Radial is made up of the bigbore vertical shaft of a bite and several level set water pipes thrown into from vertical shaft water-bearing layer either direction, elevation towards periphery, due to level set water pipe radially, therefore is called radial；
Along with developing rapidly of China's modernization construction, urban construction is maked rapid progress, and in urban construction, the development of the indispensable municipal works closely bound up with civil plantation is also more and more faster.Numerous items in municipal works such as feedwater piping engineering, drainage pipeline project, heat distribution pipe network engineering, gas-fired vacuum furnace engineering, electric power pipe trench engineering etc. are likely to pass through housing-group, busy street, highway, railway, river course etc., for the impact of urban life, traffic etc. is reduced to bottom line, reduce removal amount, reducing construction investment, these engineerings often adopt the construction technology such as bored tunnel, push pipe to construct.If construction site level of ground water is higher, then these pipeline constructions also need to lowering of watertable.With conventional precipitation method, because there is no well spacing place, do not realize at all.
Utility model content
Prior art is difficult to the problem solving presently, there are, and for making up prior art deficiency, this utility model aims to provide a kind of radial well dewatering structure.
For achieving the above object, this utility model by the following technical solutions: a kind of radial well dewatering structure, at least include vertical shaft, collector pipe, vertical shaft supporting seat, aquitard, water barrier, pipeline base plate and water-bearing layer；Described collector pipe is arranged in the water-bearing layer at vertical shaft place；Described pipeline base plate is positioned at upper end, water-bearing layer；Described water barrier is arranged on aquitard bottom；Described vertical shaft supporting seat is fixedly installed on vertical shaft bottom；Described vertical shaft supporting seat is positioned at bottom, water-bearing layer.
As further technical scheme of the present utility model: described collector pipe is arranged vertical shaft bottom even level radially, and pipeline base plate covers as collector pipe upper end.
The beneficial effects of the utility model are: this radial well dewatering structure, reduce the level of ground water of similar engineering by Radiation Well Water Level Lowering Technology, solve this difficult problem admirably.It addition, radial well dewatering is applicable to all kinds of stratum, its well depth and drawdown are unrestricted, though cannot the engineering of drainage also can solve preferably with the precipitation method of routine for having site condition in municipal works.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1～3, in this utility model embodiment, a kind of radial well dewatering structure, at least include vertical shaft 1, collector pipe 2, vertical shaft supporting seat 3, aquitard 4, water barrier 5, pipeline base plate 6 and water-bearing layer 7；Described collector pipe 2 is arranged in the water-bearing layer 7 at vertical shaft 1 place；Described pipeline base plate 6 is positioned at upper end, water-bearing layer 7；Described water barrier 5 is arranged on aquitard 4 bottom；Described vertical shaft supporting seat 3 is fixedly installed on vertical shaft 1 bottom；Described vertical shaft supporting seat 3 is positioned at bottom, water-bearing layer 7.
As further technical scheme of the present utility model: described collector pipe 2 is arranged vertical shaft 1 bottom even level radially, and pipeline base plate 6 covers as collector pipe 2 upper end.
This utility model is when using filter pipe:
Rigidity filter pipe: suitable in highly permeable stratum, as in, coarse sand, sand gravel, cobble stratum, process with steel pipe, porosity is greater than the permeability on stratum, additionally also have concrete bar shaped pipe, pipe external diameter 108～273mm.
(2) flexible filter pipe: suitable in fine sand, Extra-fine sand, flour sand, silt, sub-viscous scholar, the viscous weak water penetration stratum such as scholar, silt soil.Filter pipe is double thread ripple PVC (or PE) pipe, and external diameter has 63mm and 75mm two kinds, wall thickness 0.8～1.1mm, is equipped with rectangle eyelet, porosity 1.4% at corrugated tube trough, is tied with polypropylene fiber silk as filter material in the trough of usual corrugated tube.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model.Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved.
The above; it is only preferred embodiment of the present utility model; not in order to limit this utility model, every any trickle amendment, equivalent replacement and improvement above example made according to technical spirit of the present utility model, should be included within the protection domain of technical solutions of the utility model.
