He Kupu Whakataki Ki Te Tikanga Hanga
Ko te rotator casing he momo drill hou me te whakauru o te mana hydraulic katoa me te tuku, me te mana whakakotahi o te miihini, te mana me te wai. He hangarau keri hou, he pai ki te taiao me te tino pai. I nga tau kua pahure ake nei, kua whakamahia nuitia i roto i nga kaupapa penei i te hanga o te ara o te taone nui, te puranga toi o te papa hohonu o te rua turanga, te whakawātea i nga puranga ururua (raro o raro), te tereina tereina, te rori me te piriti, me nga puranga hanga taone, me te whakakaha ake i te papuni wai.
Ko te rangahau angitu o tenei tikanga tukanga hou kua mohio ki nga huarahi mo nga kaimahi hangahanga ki te whakahaere i te hanga o te putorino putunga, te puranga displacement, me te pakitara tonu o raro o te whenua, tae atu ki nga huarahi e taea ai e te putorino-paipa me te arai arai ki te haere i roto i te. he maha nga turanga puranga kaore he arai, i te wa e arai ana, penei i te kirikiri me te toka toka, te hanga ana, te kirikiri tere matotoru, te kaha o te hanga kaki ki raro, te maha o nga turanga puranga me te rino. te hanganga raima whakakaha, kaore e tangohia.
Ko te tikanga hanga o te casing rotator kua oti pai nga mahi hanga o nga kaupapa neke atu i te 5000 i nga waahi o Singapore, Japan, Takiwa o Hongkong, Shanghai, Hangzhou, Beijing me Tianjin. Ko te tikanga ka whai waahi nui ake i roto i nga mahi hanga taone me etahi atu mara hanga turanga puranga.
( 1 ) He puranga turanga, he pakitara tonu
He puranga turanga mo te tereina tereina, te rori me te piriti me te hanga whare.
Ko nga hanganga puranga totika e tika ana kia keria, penei i nga papa o raro, nga hoahoanga o raro, nga pakitara tonu.
He pakitara pupuri wai mo te whakakaha i te puna.
( 2 ) Te keri kirikiri, toka toka me nga ana karst
E whakaaetia ana te whakahaere i te hanga puranga turanga ki nga whenua maunga me nga kirikiri me nga toka.
Ka taea te whakahaere me te maka i nga puranga turanga ki te hanganga o te onepu tere me te kaki ki raro i te paparanga, te paparanga whakakii ranei.
Whakahaerehia te keri toka ki te papa toka, makahia te puranga turanga.
( 3 ) Whakakorea nga arai i raro i te whenua
I te wa o te hanga taone me te hanga piriti, ka taea te whakakore tika i nga aukati penei i te raima raima whakakaha, te putunga paipa maitai, te puranga maitai H, te puranga pc me te puranga rakau ka taea te whakakore tika, ka maka i te puranga turanga ki runga i te waahi.
( 4 ) Tapahia te papa toka
Whakahaerehia te keri toka ki nga puranga maka ki roto.
Porohia he kohao ki runga i te moenga toka (nga rakau me nga kohao hau)
( 5 ) Te keri hohonu
Whakahaerehia te whakarewanga i roto i te waahi, te putu paipa rino ranei te whakauru mo te pai ake o te turanga.
Te keri i nga puna hohonu hei whakamahi i nga hanganga o te awaawa me te kauhanga.
Ko nga painga o te tango i te hurihanga casing mo te hanga
1)Kare he haruru, kaore he wiri, he haumaru teitei;
2)Kare he paru, he mata mahi ma, he pai te atawhai o te taiao, te karo i te uru o te paru ki roto i te raima, te pai o te puranga, te whakarei ake i te ahotea here o te raima ki te pae maitai;
3)I te wa o te mahi keri, ka taea te wehe tika nga ahuatanga o te papa me te toka;
4) He tere te tere o te keri, ka tae ki te 14m/h mo te paparanga oneone whanui;
5) He nui te hohonu o te keri, ka tae ki te 80m e ai ki te ahuatanga o te paparanga oneone;
6)Ko te kohao hanga poutū he ngawari ki te rangatira, ka taea te tika ki te 1/500;
7)Kare he kohao ka pakaru, ka nui te kounga o te hanga kohao.
8) He paerewa te kohao hanga diameter, he iti te take whakakii. Ka whakatauritea ki etahi atu tikanga hanga poka, ka taea e ia te whakaora i te nui o te whakamahi raima;
9)Ko te whakawāteatanga o te kohao he tino me te tere. Ko te paru keri i te raro o te poka ka marama ki te 3.0cm.
