Monga tonse tikudziwa, kusankha kwa magawo ofunikira a makina obowola mozungulira kumatsimikizira moyo wake wautumiki. Pazimenezi, Sinovo, wopanga makina obowola mozungulira, awonetsa momwe angasankhire zidebe zobowola.
1. Sankhani zidebe zobowola molingana ndi momwe zinthu zilili
Ntchito yaikulu yapobowola makina ozungulirandi kupanga pobowo pamwamba, ndi chinthu ntchito thanthwe. Chifukwa chakuya pang'ono kwa dzenje la mulu lomwe linamangidwa, thanthwelo lakhala likusintha movutikira, kukula kwa tinthu, porosity, cementation, zochitika ndi mphamvu zopondereza kudzera mukuyenda kwa tectonic ndi zochitika zachilengedwe zamakina ndi mankhwala, kotero kuti chinthu chogwira ntchito cha rotary pobowola chowongolera. ndizovuta kwambiri.
Pomaliza, pali magulu otsatirawa.
Malinga ndi lithology, imagawidwa kukhala shale, sandstone, laimu, granite, etc.
Malinga ndi genesis, imatha kugawidwa mu miyala ya magmatic, sedimentary rock ndi metamorphic rock;
Malinga ndi mphamvu zamakina, zimagawidwa kukhala zolimba, pulasitiki komanso zotayirira. Ndiye mungasankhe bwanji kubowola molingana ndi mapangidwe? Awa ndi ma introduction classified:
(1) Dongo: Chidebe chobowola chozungulira chokhala ndi gawo limodzi pansi chimasankhidwa. Ngati m'mimba mwake ndi waung'ono, zidebe ziwiri kapena kubowola ndi mbale zotsitsa zitha kugwiritsidwa ntchito.
(2) Dothi, dothi lolimba lolimba lolimba, dothi lamchenga ndi nsangalabwi wosanjikiza bwino ndi simenti yaing'ono komanso kukula kwa tinthu tating'ono kumatha kukhala ndi ndowa ziwiri zoboola pansi.
(3) Mastic olimba: Chidebe chobowola chozungulira chokhala ndi dothi limodzi lolowera (pansi limodzi ndi pawiri) kapena zowongoka zokhala ndi mano a ndowa ziyenera kusankhidwa.
(4) Permafrost layer: chidebe chowongoka cha auger ndi chidebe chobowola chozungulira zitha kugwiritsidwa ntchito kwa omwe alibe madzi oundana ochepa, ndipo kachulukidwe kakang'ono kamatha kugwiritsidwa ntchito kwa omwe ali ndi ayezi wamkulu. Tikumbukenso kuti auger bit ndi othandiza pa nthaka wosanjikiza (kupatula sludge), koma ayenera kugwiritsidwa ntchito ngati palibe madzi pansi pa nthaka kupewa kupanikizana chifukwa kuyamwa.
(5) Timiyala ndi miyala yokhala ndi simenti ndi miyala yopindika mwamphamvu: konikoni kozungulira kozungulira ndi ndowa yobowola pansi pawiri iyenera kukhala ndi zida (doko limodzi la kukula kwa tinthu ting'onoting'ono ndi doko lawiri la tinthu tating'onoting'ono)

(7) Mwala wopindika pang'ono: wokhala ndi mbiya ya cone - conical spiral bit - chidebe chobowola pansi pawiri. Ngati m'mimba mwake ndi waukulu kwambiri, njira yobowola yokhazikika iyenera kutengedwa.
