Summary of the invention
The utility model technical issues that need to address are to provide a kind of equipment for ground water fixed depth sampling and injection, and this equipment, after inspection well or injector well construction, can carry out sampling or injection operation under designated depth.
For solving above-mentioned technical matters, a kind of equipment for ground water fixed depth sampling and injection of the present utility model; Comprise screen casing, on screen casing wall, be laid with sieve aperture; In described screen casing, be provided with plugging device, plugging device coordinates as adaptability with described screen casing.
Further, described plugging device is vulcanie plug, and described vulcanie plug is hollow cylinder structure, between vulcanie plug and described screen casing, is interference fit; Described vulcanie plug is divided into epimere rubber plug and hypomere rubber plug, and the screen casing between epimere vulcanie plug and lower end vulcanie plug is sampling injection portion.
Further, described epimere vulcanie plug and hypomere vulcanie are fixed with lead beyond the Great Wall.
Further, described plugging device is air bag, and described air bag is hollow cylinder shape, external inflation device to airbag aeration after and between described screen casing, be interference fit; Described air bag is divided into epimere air bag and hypomere air bag, and the screen casing between epimere air bag and lower end air bag is sampling injection portion.
Further, on described epimere air bag and hypomere air bag, be fixed with lead.
Principle of work of the present utility model: utilize plugging device by the screen casing shutoff without sampling or injection depth, only leave the screen casing that needs sampling or injection portion, and screen casing is put into the tested degree of depth, medicament is from screen casing top flows into, in this section of screen casing, flow out to deep-well, reach the object of injection; Or screen casing is put into the tested degree of depth of deep-well, and contaminated underground water flows into by this section of screen casing, can carry out sampling of water quality at well head.And plugging material moves up and down the degree of depth that can change sampling or injection in screen casing, after certain a bite well sampling, injection, plugging material is recyclable for lower a bite well.
The beneficial effect that the utility model brings is: by plugging material, the screen casing beyond target phase is carried out to shutoff, prevent that its underground water and water WIH around from exchanging, after shutoff completes, can directly in well, sample or inject, easy to operate, apparatus structure is simple, cost is not high, suitable wideling popularize.
