Kōhao puna wai tena i: hangarau. Whakamanatanga mō te pai te wai kōhao

Kōhao puna wai tena i tā te hanga o te puna pēhanga e tutuki aquifer raina wāhi pākeho. puna wai tena i kei i te hohonu i roto i te whānuitanga 20-200 mm o me whai wai viivii ore maere.

whiwhi i te whakaaetanga

Ki te hiahia koe ki te waihanga i tētahi poka, e ka whai i te hohonu iti ki te 5 m, e taea te kawea te mahi i roto i waho whiwhi whakaaetanga. I roto i tenei take, ka tae koe pae unconfined. Ko te tono ki to ratou ake hiahia wai tena i te wai titau te whakaaetanga. he whakaaetanga pērā ki te wiri he he puna wai tena i ahua o raihana, a ki te riro tona rangatira, he mea e tika ana ki te kohikohi i te tuhinga, tae atu ki: te riihi i runga i te whenua, mahere cadastral, te whanaketanga mahere āhuatanga whānui. I roto i te taahiraa i muri mai, te faaotiraa o te nui o te kai te wai. Ko te whika hoatu i roto i te wehea te wai, i muri anake i tenei potrebnadzor Russian homai whakaaetanga ki te whakarite i rohe parukore o te rohe tuatahi e tata ana te borehole i te pae ngā. Na ka taea e koe te neke i runga i ki te faaineineraa o whakatau i runga i te whakatinanatanga o te ahanoa hoahoa. Ka taea te whiwhi i tēnei tuhinga i te pokapū o te aroturuki kāwanatanga o huru aa. pepa katoa i tukuna ki te Tari mō te whakamahi aa, te wahi me te ka e waiho reira taea ki te whiwhi i te raihana. Ki reira, tahuri te tangata ki te whakahaere ki te whakawhanake. Runga ki te whakaotinga o te poka hoatu i runga i record.

pūrere Āhuatanga poka

kia kawea ai kōhao pai Water i na tetahi o te maha kōwhiringa e wātea ana. Ka te kōwhiringa e tākiekina e maha o ngā āhuatanga, i roto ia ratou:

• mahi e hiahiatia ana (e whakawhirinaki enei tawhā i runga i ngā āhuatanga hangarau o te kōwae papu me te diameter whakamahia i roto i te casing);
• nga āhuatanga arowhenua o te rohe.

Ki te tikanga te reira ki te arotahi ki runga i te hanga poka nei kaha kore e nui ake 5 m ³ / haora, Kei te te tikanga e whakamahia ana papua Ø100 mm. Ahakoa te hua, e kore rawa 3 m ³ / h, tohu te hiahia ki te whakamahi i te papu Ø75 mm.

Ngā momo o puna wai tena i

Pai ngā wiri whenua tono momo puāwaitanga te ka huia te pēhanga i roto i te aquifer pai nui, me te pākeho putunga paru, me te onepu arotahi. Ko te paparanga o runga ko tenei kia noa.

kia kawea casing ki te raina runga o te aquifer. I muri te whakatau i roto i te tuwhera ki te diameter i te mea iti iho i te tenei ahua, casing āhuatanga oko pākeho. Na roto i tenei whakatuwheratanga ô te wai ki te puna. Kei te papu e raro i te aranga taumata wai 10 m. Heoi, kua tikanga ai i roto i te casing.

Pai ngā wiri whenua rua momo casing oscillator te whakamahia, ka tangohia te aquifer te o te pēhanga. Pai tenei kōwhiringa mo te take i reira e tito o tīwhana onepu etahi inclusions o uku ranei nga papa o runga o te pākeho. Taputapu, i te puna, i kawea mai te ariki e ki te pākeho raina putorino tuatahi, te mea i roto i te apa rua, me whai i te reira i te diameter iti whakamīharo.

kia whai wāhi puna wai tena i te supply o kaiwhakahaere. Ana tēnei tikanga te whakamahia te wahi pokanoa nga paparanga o runga ki te kōhao, ko te wai i roto i te aquifer raro i te pēhanga. e kore he tino rerekē i te poka mua he pūnaha taua, engari, rite whakahuatia, ko te pēne. Tenei huānga kōwhiri ko te putorino ki te diameter rahi rite whakaritea ki tenei āhuatanga, moku, ki te casing.

He pūrere tikanga wellbore kē

Ka taea te hua kōhao o boreholes i te whakawhitinga ki te putorino ki te diameter o iti faahiahia. Ahei te mau atu taua mahi i raro i ngā papa noa runga e he one wewete, kohatu etc .. kia rerekē Aquifers marutuna pēhanga, mea kia kia takina pākeho mo te ngaro o te paru me te onepu putunga. whakahaere noa-diameter wahi ngongo te ki te matatini, engari i roto i ngā wāhi raruraru - i te putorino ki te diameter iti. tāuta te reira i te te papu.

Te tohu i te wāhi o te poka

I mua i kawea te kōhao te boreholes mo wai, he mea e tika ana ki te whakatau i to ratou wāhi. He mea nui ki te tautuhi me te wāhi o te tāutanga, me te te rohe riringi fluids. whiriwhiri te rohe o te mahi kei te tango ki te pūkete te meka i ko reira tata ki te wāhi o te tomokanga. ka pā te reira i te roa o te rua, putorino, me te āhuatanga o te pūrere.

Hei mahi, ka waiho reira e tika ana ki te tohatoha i te wāhi papatahi, te rahi o e ka kia whāiti ki 4x12 m. I roto i kore te pūtoro o te 2 mita kia whakanohoia waea hiko. Mahi rohe ki te kia taiepa.

A faatere kōhao

hangarau pai kōhao kōhatu tā i roto i te taahiraa matamua te whakangaromanga o te oneone, tona tupu, e whakakaha ana i te taiepa, e ekeeke o putorino me papua. whakamana te tukanga rawa o te kōhao e waeine pūkoro i roto i paraire tihi. kawea mahi i roto i roto i whakarara ki te otinga horoi. E āwhina ana tēnei tikanga ki te ara te wahi i toka.

Kia haere te reira i te kahu o runga o te onepu, te uku me te pākeho tae i casing tāuta whakamutunga o nga ngongo e mawehe meake taiepa. I muri i te akoranga, ko te diameter moka iti faahiahia, e hora i te pākeho aquifer. Ko te kupu nekehia tonu oneone me whakaurua ki roto ki te aho production. A, no te tae i te absorption o otinga horoi te uara e hiahiatia, discourages taumata wai te rangatira. Ki te taea te hanga e tika ana i tenei wā o te whakatō wellbore i roto i te pākeho putorino kore he diameter pera nui.

Takitahi hanga he tino uaua, e kore e ki te mea e he e taea ki te mahi i taua mahi. I muri i te katoa, me whai koe i te wheako me te taputapu e tika ana. Ahakoa te ngaio kawe i te tukanga kōhao i roto i te wa ka taea poto, te whakarite te kounga wai.
