Whāurutau Wells - tikanga otinga pai Modern

Faanahonahoraa wai i runga i tou pae whenua, whai ki te whakaoti i te rota o ngā pātai. Hei tauira, me pehea pai tāne rite ki te whakarato i te poka hiri i roto i te paetaha, whiriwhiri he papu pai, me te nui atu. I roto i toa nga kanohi te mahuetanga i te nui o te taputapu downhole. Ki te kōrero tatou e pā ana ki te tapatahi o te here-i roto i te pai, engari inaianei i reira e wha kē taketake: he pai, he teneti, he caisson hoki poka, me poka whāurutau. rerekē ratou i ia atu i te utu, whānuitanga o te mahi, me te tika. Hei timata, te waiho i te tikanga tuatahi e rua mō ngā take whāinga (puna - ko te tino hārakiraki, a he pera tiketike teneti utu e whakamahia ratou anake i roto i te whakahaere o te wai ngā). Na reira, i roto i tenei tuhinga ka arotahi tatou i runga i te rua tikanga tino rongonui o te whakaritenga o puna wai: caissons me whāurutau borehole.

Caisson Ko te oko nui i hanga o kirihou whakarewa ranei, e kua he poka i te raro (ki te tomo i te casing o te puna), me te kohao ki te manhole i te tihi.

Hoki te caissons whakarewa wa roa mo te poka ko he monopolist i te whenua supply whakaritenga. utu nui, whīwhiwhi o tāutanga, āhuatanga whakamīharo me te taimaha, te uara rerehua nanakia, tiaki rawakore ki te whakatuwheratanga ture: he tokomaha o drawbacks enei hua i. Ko te drawback matua - ko reira tata oti mii ki te waikura. Na ka haere mai nga caissons kirihou, i roto i nei i reira ko te painga nui i runga i caissons whakarewa: e kore e Plastic waikura. Otiia kāore e kore, kahore huakore: caissons hou i iti rawa ātete ki te pēhanga oneone. E whakaritea ana tēnei ngoikoretanga te ngoikore ki te tāuta caissons kirihou wahi he tiketike nui te taumata manawa whenua.

Kia aroha mai e kore e ranei, nga tohu ko e te wa o caissons mōmona utu mai ki te mutunga - te wahi o te whakataetae tuku ratou whanaunga ake tōtika, me te kiato ki ia ra e haere riro te reira atu me te ake. Mō ahakoa he pai, ahakoa kino, ka taea e te mea he tino roa te wa ki te totohe, ko te mo'oni ko e kiritaki e piki hiahia i roto i te kupu whakahoki ki te pātai "aha te mea pai ki te hoko i tētahi whāurutau mo te poka."

Whāurutau mō puna (Eng. Pitless whāurutau) puta ngā tata, i roto i nga 60raa o te rau tau whakamutunga, engari anake i roto i te waenganui-80, kua riro ratou rongonui i roto i kiritaki. Pitless-whāurutau he hiri paipa pēhanga wai, hanga o te parahi parahi ranei.

Ki te hiahia koe ki te hoko i te pūurutau pai, kia waiho koutou mōhio o te rerekētanga i waenganui i parahi, me te parahi whare. Parahi, me te parahi alloys he momo parahi mo e whakamahi rerekē wae alloying. doped parahi te whakamahi i konutea, i te parahi - rerekē konganuku anake te konutea me te konukōreko. nui parahi parahi i runga i te parenga te waikura o nga āhuatanga pūkaha me anti-waku. he kainga i roto i te hau, te wai moana, otinga waikawa carbonic me ngā rongoā o te nuinga o ngā waikawa waro parahi. Ka rite ki te putanga, i roto i te whāurutau parahi e kore fakamamafa'i e puta waikura papatanga. E kore e Leach reira konutea. Kaua e i roto i te pūnaha wai o konganuku taimaha pērā i konukoreko me te mata. Hoki e kore e tatou e wareware e kotahi whakawehe parahi i waenganui i ngā rauemi e rua rerekē e tauturu i ki te ārai i te āhuatanga o te waikura galvanic. Ko te drawback anake o taonga parahi i roto i mua o te parahi, ko to ratou utu. Ko te tika ki te ihirangi teitei o parahi i roto i te parahi tenei.

Whakarāpopoto, ka taea e tatou te mea e ki te whakatau i nga whakaritenga mā, he uaua ki te mahi i ngā paerewa o te tika, me te mauroa i waho te whakamahi o ngā whāurutau parahi borehole.
