Technical Principle
DTH sando uye tekinoroji yekuchera tekinoroji inzira yekuchera iyo inosanganisa kukurumidza kubatsirwa kwemhepo DTH kuchera sando uye zvakanakira casing madziro ekudzivirira inoenderana nekugadzikana kwechibhorani chibhorani.Pakuchera, eccentric drill inokandwa kunze kana eccentric block inotenderedzwa kumberi.Iyo dhayamita yekukandwa eccentric drill yakakura kupfuura dhayamita yepakati drill.Paunenge uchichera, iyo casing inotungamirirwa neshangu yepombi kutevera synchronously, uye pombi yesimbi isina musono inodzivirira Zvakakosha zvikuru kudzikamisa rusvingo rwegomba rekubatanidzwa kwekuongorora nekugadzirwa zvakanaka kudzivirira rusvingo rwegomba kubva pakudonha uye kuparara.Kana iyo eccentric drill bit ichidhiriwa kusvika pakuumbwa kwakazara, mushure mekudhirowa 0.5 ~ 1 m, iyo eccentric block inodzoserwa nekudzoreredza, uye ipapo eccentric drill inodzoserwa kubva kune inodzivirira madziro casing, kuitira kuti iyo quaternary system inogona kufambiswa zvakanaka. .Kuremerwa uye kuputsika kwakaoma stratum.
Unyanzvi hunoita
1. Iyo yakadzika-iyo-gomba nyundo uye tekinoroji yekuchera chubhu inoshandisa zvakazara zvakanakira pneumatic pasi-the-gomba sando kukurumidza kuputsa dombo, izvo zvinobatsira mukusimudzira uye kuita kwekubatanidzwa kwekuongorora uye matsime ekugadzira muhydrogeological. ongororo.
2. Tekinoroji yekuchera tekinoroji inogona kutevedzera iyo casing paunenge uchichera.Hazvidi mvura nemadhaka ekuchera, kunyanya munzvimbo dzakaoma uye dzisina mvura.Inogona kuita kaviri kuedza nehafu yekuedza, kudzivirira kuoma kwekutenga mvura yekuchera, nekuvandudza kushanda zvakanaka.Kuvandudza kwacho kunobatsira zvikuru.
3. Mhando iyi yekuchera teknolojia inoshandisa synchronous kutevera-up casing kuchengetedza rusvingo paunenge uchichera, kushandisa zvizere zvakanakira mhepo DTH nyundo kukurumidza kuputsa dombo, uchichengetedza gomba remadziro echina mutsara wezvisina simba zvinorema pamusoro. nechepamusoro pechibhorani chibhorani.Iyo yakatsemuka yekucheka inotakurwa kunze kwegomba nekumhanya-mhanya kwemhepo kuyerera, uye iyo yekusveta mhedzisiro inobatsira pakuvhurwa kwegeji rekubuda kwemvura.Kuramba kugezwa kwegomba remadziro nemhepo inomhanya-mhanya zvakare kupfupisa nguva yekugezesa matsime, iyo inobatsira pakuvandudza kwekuchera kwehydrogeological uye kunyatso pedzisa.
4. Iyo yakadzika-iyo-hole nyundo uye pombi yekuchera tekinoroji inokodzera kudhirowa kwedombo rakaoma.Kune maumbirwo evhu kana maumbirwo akapfava akafanana, zviri nyore kuvhara nzira yemhepo uye madhiri akachekwa ari nyore kuturika pamadziro egomba kuti agadzire dhaka plug, izvo zvakaoma kuwana yakanakira kudhirowa kunyatsoita .
5. Chivharo chakakonzerwa nenyundo yakadzika pasi nepombi inobudiswa kunze nemichina yakakosha mushure mekupedza basa rekudzivirira kwemadziro, iyo inogona kushandiswa zvakare mukati meimwe nguva yenguva, kuderedza mari yekuvaka.
