DTH nyundo ndi makina obowola chubu ndi njira yobowola yomwe imaphatikiza kuthamanga kwa mpweya wa DTH pobowola nyundo komanso ubwino wa chitetezo cha khoma chomwe chimapangitsa kukhazikika kwa khoma la borehole.Pobowola, kubowola kwa eccentric kumatayidwa kunja pomwe chipikacho chimazungulira kutsogolo.Kubowola kwa eccentric ndikokulirapo kuposa kukula kwa pakati.Pobowola, casing imayendetsedwa ndi nsapato ya chitoliro kuti itsatire synchronously, ndipo chitoliro chachitsulo chosasunthika chimateteza Ndikofunika kwambiri kukhazikika kwa khoma la dzenje la kufufuza kophatikizana ndi kupanga bwino kuteteza khoma la dzenje kuti lisagwe ndi kugwa.Kubowola kwa eccentric kumabowoleredwa mpaka kumapangidwira, pambuyo pobowola 0.5 ~ 1 m, chipikacho chimachotsedwa ndikubweza, ndiyeno kubowola kwa eccentric kumachotsedwa pakhoma lachitetezo, kuti dongosolo la quaternary lidulidwe bwino. .Zolemetsa komanso zosweka zovuta stratum.
Makhalidwe aukadaulo
1. Ukadaulo wa nyundo wapansi-bowo ndi ukadaulo wakubowola chubu umagwiritsa ntchito mokwanira ubwino wa nyundo ya pneumatic pansi pa dzenje kuti ithyole thanthwe, zomwe zimathandizira pakupanga ndi kukhazikitsa zitsime zophatikizana zofufuza ndi kupanga mu hydrogeological. kafukufuku.
2. Ukadaulo wobowola wotsatira ukhoza kutsatira pobowola pobowola.Sichifuna madzi ndi matope obowola, makamaka m'madera ouma ndi opanda madzi.Ikhoza kuwirikiza kawiri ndi theka la khama, kupewa zovuta kugula madzi obowola, ndi kupititsa patsogolo ntchito yabwino.Kusinthako kumapindulitsa kwambiri.
3. Mtundu uwu wa luso pobowola ntchito synchronous kutsatira casing kuteteza khoma pamene kubowola, kugwiritsa ntchito mokwanira ubwino mpweya DTH nyundo mwamsanga kuthyola thanthwe, ndi kusunga dzenje khoma la mndandanda wachinayi wa ofooka olemerera pa. kumtunda kwa khola la borebole.Zodulidwa zosweka zimatuluka mu dzenje ndi kutuluka kwa mpweya wothamanga kwambiri, ndipo kuyamwa kumapindulitsa pakutsegula kwa njira yotulutsira madzi.Kutsuka kosalekeza kwa khoma la dzenje ndi mpweya wothamanga kwambiri kudzafupikitsa nthawi yotsuka bwino, yomwe imakhala yopindulitsa pakubowola kwa hydrogeological ndikumaliza bwino.
4. Ukadaulo wobowola nyundo pansi ndi chitoliro ndi woyenera pobowola miyala yolimba.Pakuti mapangidwe dongo kapena ofanana mapangidwe zofewa, n'zosavuta kuletsa mpweya ndimeyi ndi kutayidwa kubowola cuttings n'zosavuta kupachika pa dzenje khoma kupanga pulagi matope, amene n'zovuta kukwaniritsa bwino pobowola dzuwa .
5. Chophimba chopangidwa ndi nyundo yotsika pansi ndi chitoliro chimatulutsidwa ndi zipangizo zapadera pambuyo pomaliza ntchito yoteteza khoma, yomwe imatha kubwezeretsedwanso mkati mwa nthawi inayake, kuchepetsa ndalama zomanga.
