Description
one, technical field
The utility model relates to groundwater resources field, particularly a kind of artesian water water intake well.
two, prior art
At scall, high-pressure artesian aqua region carries out hydrological well and drills in well construction, due to during hydrological well mostly is, deep hole (100-300 rice), in stratum, water barrier mostly is silty clay, underground water has certain pressure, by conventional hydrological well drilling operation technique, become well difficulty, multiple well kick, the outer water burst accident of pipe well, while there is water burst, if do not adopted an effective measure, the soil sheet of well head periphery is submerged or will becomes pond, producing to local people life brings inconvenience, once well head is blocked, all that has been achieved is spoiled in that well-digging work before this, meaningless, also do not have at present a kind of construction method of rational artesian water water intake well to solve time contradiction.
three, utility model content
The problem existing for above-mentioned prior art, the utility model provides a kind of artesian water water intake well, a kind of artesian water water intake well, its structure is: the top of wall casing (6) is fixed with flange (11), the bottom of wall casing (6) is provided with filter pipe (10), the arranged outside of the top wall casing (6) of filter pipe (10) has sealing pallet (8), sealing pallet (8) is provided with the interim sealing material (9) that is inverted triangle, the outside of wall casing (6) is also provided with expansion watertight rubber circle A(7), the outside of wall casing (6) is also provided with guide pipe (4), the arranged outside of guide pipe (4) has expansion watertight rubber circle B(3), concrete cement paste (5) is all poured between wall casing (6) and guide pipe (4) and guide pipe (4) outside, guide pipe (4) top is provided with guide pipe cover plate (1) and guide pipe sealing Grouting Pipe (2).
The utility model is achieved in that the first step: landfill guide pipe: the degree of depth of determining relative water resisting layer according to geologic information, relatively stable water barrier is: farinose argillic horizon or other impervious layers, thickness is greater than 3m, the length of guide pipe is generally designed to 15～30m, the bore of guide pipe be greater than pipe well well casing bore 2～3 times; The position of the outside relative water resisting layer of guide pipe adopts upper and lower back-up ring and galvanized wire to tie up fixedly sealing expanded rubber, sealing expanded rubber is wide is 300～500mm, thickness is 20～40mm, back-up ring thickness is 10～20mm, back-up ring spacing is consistent with sealing expanded rubber width, adopts pipe method under tubing string lifting that guide pipe is installed; Concrete cement paste is injected by grouting pipe in the outside of guide pipe, and the relative density of concrete cement paste should be 1.3 times of field measurement mud density;
Second step: revolve and scrape out well: adopt normal circulation slewing drilling machine to enter successively to revolve and dig in the middle of the mounted guide pipe of the first step, revolve and dig to projected depth;
The 3rd step: wall casing is installed: the wall casing in reducing sealing position is fixed with pallet, pallet diameter is less than bore open 50mm, thickness 20～30mm, pallet is selected steel material, pallet below sea-tangle braiding, is wound around, and galvanized wire is tied up fixing, wall casing inside is provided with the wall casing of filter pipe, and wall casing is: 6～10mm ordinary steel; At second step, revolve in scraping out well and adopt pipe method under tubing string lifting that wall casing is installed;
The 4th step: well-flushing: install after wall casing in the 3rd step, to start in time well-flushing work, the main purpose of well-flushing is in order thoroughly to remove mud in well, destroy borehole wall mud skin, extract the mud and the fine particle that infiltrate in aquifer out, make strainer form a good artificial filtration beds around, to increase the water yield of wellhole, due at scall, high-pressure artesian aqua region Cheng Jing, can adopt note clear water circulation well cleanup, as effect is undesirable, adopt chemical well-flushing method (to use the aqueous solution of sodium pyrophosphate 10%, drop in well and soak after 24 hours, adopt again Piston Air Compressor combined washing well) can take effect.
The beneficial effects of the utility model are: the utility model is simple in structure, easy construction, and cost is low, at scall, high-pressure artesian aqua region hydrological well, drill into the high well completion rate of well, easy to use, water rate is good, and can control well kick, the outer water burst of pipe well completely.
