Miihini jet grouting me te huinga oti

Ko te hangarau Jet Grouting he tikanga whakapai oneone hou e whakamahia nuitia ana i roto i te whakakaha turanga, te whakahaere wai whenua, me nga kaupapa tiaki taiao. Ka whakaranuhia e ia te ciment, te oneone, me etahi atu taapiri na roto i te pehanga nui-nui hei whakaputa i te tinana oneone-sima me te kaha teitei me te iti o te uruhanga. Na te piki haere o te tono miihini, kua riro te miihini jet grouting me te huinga oti hei whiringa rongonui i te maakete o te ao.

Ko te miihini jet grouting me te huinga kua oti te whakauru i nga waahanga matua e whai ake nei:

He papu jet grouting pehanga teitei: Ka whakamahia kia nui te pehanga ki te rehu slurry sima ki roto i te oneone i roto i te puha hei hanga ranunga.
Pūnaha whakangao: Ka whakamahia he punaha paipa ki te kawe i te puhu sima me etahi atu taapiri ki te pupuha.
Pūnaha whakahaere: Ka taea e te punaha whakahaere matatau te aro turuki me te whakatika i nga tawhā penei i te pehanga me te rere i roto i te waa tuuturu hei whakarite i te kounga o te grouting.
Nga taputapu awhina: tae atu ki nga taputapu keri, nga taputapu whakaranu, me nga taputapu kawe hei whakarite i te mahi pai me te maeneene katoa.

Ka whakaratohia e matou he taputapu jet grouting kotahi-mutu, tae atu ki te hurihuri jet drilling rig, punga drilling rig, grouting mixer, jet grouting pump, jet grouting tipu, paru paru, me te ngongo ngongo.

I roto i nga mahi miihini, ka whakamahia nuitia te hangarau jet grouting. Hei tauira, i roto i te kaupapa hanga o tetahi taone nui i Qatar, hei whakarei ake i te kaha o te kawe i te oneone i raro i te whenua, i whiriwhiria e te waahanga hanga ki te whakamahi i te miihini jet grouting me te huinga katoa mo te whakapakari turanga. I roto i te kaupapa, i tangohia e ratou to maatau tauira hou o nga taputapu jet grouting, HWGP 400/700/80 DPL-D Diesel jet grouting tipu.

I te wa o te mahi hangahanga, i ata tirotirohia e nga miihini te rere me te pehanga o te slurry i roto i te punaha whakahaere me te hanga angitu i tetahi tinana whakakotahi i te hohonutanga kua whakaritea. Ko nga raraunga whakamatautau e whakaatu ana ko te kaha o te kaha o te kaha o te tinana whakatōpū he nui atu i te whaainga e tumanakohia ana.

Ko te miihini jet grouting me te huinga katoa e whakarato ana i te otinga pai, ohaoha, me te taiao mo te whakapakari i te oneone. I roto i te maha o nga tauira miihini, kua whakaatuhia e te miihini jet grouting te mahi pai me te pono. I te mea he kaihanga miihini jet grouting, kua whakawhanakehia e to maatau kamupene te whānuitanga o nga taputapu miihini me te tumanako ki te mahi tahi me koe.
