Chigadziko chekuchera kuchera chinotenderera shureimuchina wekuchera unotenderera. Wakakodzera kuvaka zvivako zvakasiyana-siyana zvakaomarara zvakaita sejecha rinoyerera, silt, ivhu, dombo rematombo, dombo rakapwanyika, nezvimwewo, uye unoshandiswa zvakanyanya mukuvaka zvivakwa, mabhiriji, kuchengetedza mvura, matsime, magetsi, kutaurirana, kunaya kwemvura mumainjiniya nemamwe mapurojekiti.
Musimboti wekushanda wekuchera bhora rinotenderera nekumashure:
Zvinonzi reverse circulation drilling rig zvinoreva kuti kana ichishanda, rotary disc ichafambisa drill bit kuti icheke nekupwanya dombo nevhu riri mugomba, flushing fluid ichayerera ichipinda mugomba kubva pa annular gap iri pakati pe drill pipe negomba remadziro, yotonhodza drill bit, yotakura dombo ne soil drilling slag yakachekwa, yodzokera pasi kubva mu drill pipe cavity. Panguva imwe chete, flushing fluid ichadzokera mugomba kuti iite cycle. Sezvo dhayamita yemukati me drill pipe iri diki zvikuru pane ye wellbore, mvura yematope iri mu drill pipe inokwira nekukurumidza kupfuura kutenderera kwakajairika. Haingori mvura yakachena chete, asiwo inogona kuunza drilling slag pamusoro pe drill pipe uye kuyerera kuenda ku mud sedimentation tank, uko matope anogona kudzokororwa mushure mekucheneswa.
Nheyo yacho ndeyekuisa pombi yekuboorera mugomba rakazadzwa nemvura inoyerera, uye nekutenderera kwetafura inotenderera, fambisa tsvimbo yemhepo ine mativi mana uye chidimbu chekuboorera kuti uchitenderedze uye ucheke dombo nevhu. Mhepo yakamanikidzwa inopfapfaidzwa kubva mumuromo uri pamucheto wezasi wepombi yekuboorera, zvichiita musanganiswa wevhu, jecha, mvura negesi zvakareruka kupfuura mvura iri mupombi yekuboorera nevhu nejecha zvichichekwa. Nekuda kwekubatanidzwa kwemusiyano wekumanikidzwa pakati pemukati nekunze kwepombi yekuboorera uye simba rekumanikidzwa kwemhepo, musanganiswa wegesi remvura yejecha rematope uchakwira pamwe chete nemvura inoyerera, uye uchaburitswa mudziva revhu kana tangi rekuchengetera mvura kuburikidza nepaipi yekumanikidza. Ivhu, jecha, matombo nematombo zvichagara mudziva revhu, uye mvura inoyerera ichayerera zvakare mugomba.
Zvinhu zvekuchera drill rig yekutenderera kwemhepo inodzokera shure:
1. Chibhorani chekutenderera chinodzorwa nereverse chakashongedzwa neruoko rwemuchina rune pombi yekuboorera, iyo inogona kushandiswa mugomba rakatwasuka uye mamiriro madiki ekona yevertex. Panguva imwe chete, bhora rekuboorera rinewo winch yekuwedzera yehydraulic, iyo inoderedza zvakanyanya simba revashandi vemuchina, uye inobatsira pakuvaka muchina kwakachengeteka uye kwakanaka.
2. Chigadziko chekuboorera chinoshandisa hunyanzvi hwekukweva uye hydraulic walking chassis, zviri nyore kufamba uye zvakakodzera nzvimbo dzakati sandara, nzvimbo dzakatetepa, makomo nedzimwe nzvimbo. Chigadziko ichi chine ma outrigger mana, saka gomba rekuboorera harina kuzununguka zvakanyanya uye harina kugadzikana zvakanaka panguva yekuvaka gomba.
3. Chigadziko chekuboorera chinotenderera shure chinoshandiswa nesimba remagetsi, chine ruzha rwakaderera uye kusvibiswa kwakaderera, kushanda zvakanaka uye simba guru rekuchengetedza simba.
4. Muchina wekuchera bhora unotenderera shure une mabasa akawanda, uye zvese zvakakosha zvinodhura zvishoma. Sisitimu iyi ine dziviriro yekumanikidza uye midziyo yekunyevera.
5. Zvibato nezvishandiso zvema actuator ese e reverse circulation drilling rig zviri papuratifomu yekushanda, iyo iri nyore uye yakavimbika pakushanda nekudzora.
6. Chigadziko chekuboorera chinotenderera shure chinoshandisa furemu yekuboorera yakasiyana. Maitiro ekuboorera akakura, kuramba kutenderera kwakakura, chimiro chiri nyore, kugadzirisa kuri nyore, kutamiswa kuri nyore, kushanda kwechombo chekunze kuri nyore, uye kuboorera angle hombe kunogona kugadzirwa.
7. Chigadziko chekuboorera chinotenderera chinotora simba guru rine basa rekudzivirira kukanganiswa kukuru. Kumhanya kwekutenderera kwakakodzera zvinodiwa nemhepo inotenderera inotenderera. Simba rekusimudza, torque nezvimwe zvinongedzo zvinogona kusangana nezvinodiwa zve100M shallow air reverse circulation DTH drilling nezvimwe zvinodiwa pakuita basa.
