Description
Technical field
The utility model relates to water source heat pump technology field, specifically one collection backwater unification well
Structure.
Background technology
Water source heat pump technology is the solar energy and geothermal energy utilizing earth surface shallow-layer water source to absorb
And the low temperature Lowlevel thermal energy resource being formed, and use heat pump principle, logical too small amount of high-order electric energy
Input, it is achieved a kind of technology that Lowlevel thermal energy shifts to high level heat.And wet well or back water well
It is requisite part in water source heat energy technology；Prior art typically use multiple individually
Sump and back water well, so unavoidably cause construction and the increase of operating cost；This
Outward, existing back water well is not owing to blocking sand structure, and the operating silt of system can deposit and return
The filter material layer of well mouth, causes the filter material layer of backwater well head to lose efficacy, further, since do not have sand control
Along arranging, the bottom sludge causing inspection shaft is a lot, and workman checks and constructs extremely difficult.
Underground structure is divided into argillic horizon, water-bearing layer and lithosphere, existing collection typically from top to bottom
Screen pipe is typically arranged on water-bearing layer by well, and due to the souring of current during operation, mistake
The earth of the filter material layer of chimney filter both sides constantly runs off, the huge cavity 21 in causing such as Fig. 4,
This cavity silt mixes with filtrate, reduces filter effect, and needs to be continuously replenished filtrate,
This adds operating cost undoubtedly and reduces the efficiency of unit.
Content of the invention
For solving above-mentioned technical problem, the purpose of this utility model is to provide one can efficient solution
The certainly well construction of drawbacks described above, concrete technical scheme is as follows:
The water-collecting return unification well construction that a kind of screen pipe moves down, including an inspection shaft, inspection shaft
It is arranged on original soil layer；The top of inspection shaft is well lid, and through hole is left in shaft bottom, in described through hole
Well casing is set；The outside of well casing is filter material layer；It in water lift pipe inserts well casing and is connected with immersible pump；
Water lift pipe is connected with main pipeline by check valve, valve；Return pipe is arranged on the lower end of detection well,
Return pipe is connected with main pipeline by valve；Main pipeline by valve respectively with water collector and Fen Shui
Device connects；The lower end of well casing is screen pipe, and screen pipe is arranged on bottom, and screen pipe top is low
In lithosphere top.
Described valve is magnetic valve, and described valve is connected with control system.
The outside of filter material layer arranges sand control edge, and the lower end on sand control edge arranges permeable mouth；Return pipe goes out
Mouth becomes 20-60 ° with horizontal line.
Described permeable mouth is 4, is symmetrical arranged.
Screen pipe top is less than 1～2 meter of lithosphere top.
The utility model has the advantages that:
Owing to screen pipe is arranged on bottom and corresponding with lithosphere, therefore, do not result in filter
Subsiding of the bed of material, forms cavity；Further, since water is via the distance relatively prior art of filter material layer
It is greatly increased, this improves filter effect；
Owing to have employed collection backwater unification well construction, effectively reduce construction cost, and, by
It is horizontally disposed with along, water return outlet in blocking sand, it is ensured that well water meets service requirement, it is achieved that catchment
Uniting two into one of well and back water well.
Owing to return pipe mouth is horizontally disposed with, backwater can rotate in inspection shaft, and silt is at centrifugal force
And under the effect of gravity, pile up to the borehole wall lower end of inspection shaft, and backwater exceedes well head height
Part flows into back water well from well head, and is less than well head, is higher than the part on sand control edge through filter material layer
Flow into back water well, contain substantial amounts of silt less than the part on sand control edge, be mainly deposited in inspection shaft
Borehole wall lower end, the moisture containing slowly flows into back water well from permeable mouth, and silt is then retained in inspection
Looking into the borehole wall lower end of well, so, the bottom of inspection shaft does not results in Sediment Siltation.
Brief description
Fig. 1 is the structural representation within inspection shaft；
Fig. 2 is pipe connecting structure schematic diagram；
Fig. 3 is screen pipe position view；
Fig. 4 is the screen pipe position view of prior art.
Detailed description of the invention
Illustrating the utility model below in conjunction with the accompanying drawings, as Figure 1-Figure 4, this practicality is new
Type includes an inspection shaft 2, and inspection shaft 2 is arranged on original soil layer 7；The top of inspection shaft 2 is well lid
1, through hole is left in shaft bottom, arranges well casing 8 in described through hole；The outside of well casing 8 is filter material layer 4；
It in water lift pipe 14 inserts well casing and is connected with immersible pump；Water lift pipe 14 passes through check valve the 9th, valve
15 are connected with main pipeline 10；Return pipe 6 is arranged on the lower end of detection well, and return pipe 6 passes through valve
9 are connected with main pipeline 10；Main pipeline 10 by valve 9 respectively with water collector 11 and water knockout drum 12
Connect；The lower end of well casing 8 is screen pipe 19, and screen pipe 19 is arranged on bottom 20, screen pipe
19 tops 16 are less than lithosphere top 17.
Described valve 9 is magnetic valve, and described valve is connected with control system.
The outside of filter material layer 4 arranges sand control along 3, and sand control arranges permeable mouth 5 along the lower end of 3；Backwater
Pipe outlet 6 becomes 20-60 ° with horizontal line.
Described permeable mouth 5 is 4, is symmetrical arranged.
Screen pipe top 16 is less than 1～2 meter of lithosphere top, this Assurance of Size circulation of water
Fine combination with filter effect.
Well water of the present utility model can sufficiently be filtered, thus is effectively guaranteed well water
Cleannes.2nd, the setting from well head to shaft bottom of filter material layer, can prevent and solve effectively,
Because of first become well when, permeable filtrate filling is not full and that cause well water silt content makes more greatly underground
Solution cavity problem occurs.If solution cavity occurs because of above reason underground, when this well is converted to inverted well
When, the filtrate at top sediment trapping edge automatically can carry out filling from top to bottom, until filling is full be
Only.The filtrate sinking at sediment trapping edge, top can be filled out by manually carrying out benefit.Owing to water is through filter material layer
Thickness distance be greatly increased compared with prior art, this improves filter effect.Additionally, this
Plant technique also can solve because underground occurs that solution cavity causes filter material layer and subsiding of ground to ask
Topic, and increase the amount of recharging of well water.
