Izinzuzo ze-rotary drilling rig ekufakeni inqwaba kubunjiniyela bengqalasizinda

1. Umshini owodwa ungasetshenziswa ngezinhloso eziningi

Kuphrojekthi yokwakha inhloko-dolobha,umshini wokubhoboza ojikelezayoisetshenziselwa ukushayela inqwaba, ukudluliselwa kwe-hydraulic kusetshenziswa ngokugcwele, futhi indlela yokuklama inhlanganisela ye-modular iyasetshenziswa ukuze kufezwe umshini owodwa onemisebenzi eminingi ngaphansi kwesimo sokuthi umshini oyinhloko uhlala ungashintshi, ukuze kuthuthukiswe ukuzivumelanisa kwemishini emikhulu yokwakha nezindlela ezahlukene zokwakha. Luhlobo lwemishini efanele izindlela ezahlukene zokwakha. Ingenza futhi ukubhoboza i-casing noma i-casing egcwele, ifakwe i-diaphragm wall casing ngaphansi komhlaba ukuze kwakhiwe i-diaphragm wall, ukwakhiwa kwe-double power cutting head wall, kanye ne-long spiral drilling, ukuze kufezwe umshini owodwa onemisebenzi eminingi.

2. Imishini isebenza kahle, izinga eliphezulu lokuzenzakalela kanye nokuqina okuphansi kwabasebenzi

I-rotary drilling rig iyi-crawler egcwele i-hydraulic self-propelled drilling rig, esebenzisa isethi ephelele yesistimu ye-hydraulic, kanti ezinye zifakwe nesistimu yokusebenza yekhompyutha. Ukukhethwa kwezingxenye ezinhle kungandisa impilo yesevisi iyonke yemishini futhi ngeke kuthinte ukusetshenziswa kwayo ngenxa yomonakalo wengxenye eyodwa. Imishini ihlanganisa imishini, ugesi kanye noketshezi, inesakhiwo esincane, ukusebenza okuguquguqukayo nokulula, izinga eliphezulu lokusebenzisa imishini kanye nokwenza izinto ngokuzenzakalela, ingahamba yodwa endaweni yokwakha, futhi ingamela insika, elula futhi esheshayo ukuyihambisa nokulungisa indawo yembobo. Ipayipi yokubhoboza ye-telescopic iyasetshenziswa, esindisa abasebenzi kanye nesikhathi sokwengeza ipayipi yokubhoboza, isikhathi esincane sokusiza kanye nokusetshenziswa kwesikhathi esiphezulu.

3. Ukusebenza kahle kokumba okuphezulu

Ama-drill bits ahlukene angahlelwa ngokwezimo zokwakheka, kanti i-drill barrel ende ingasetshenziswa engqimbeni yomhlabathi ehlangene ukwandisa isivinini sokubhoboza; Nge-stratum enokuqukethwe okukhulu kwesihlabathi namatshe amancane, i-drill barrel emfushane ingasetshenziswa ngokuvikela udonga lodaka ukulawula izinga lokubhoboza; Ngezakhiwo eziqukethe amatshe amakhulu, amatshe amakhulu namatshe aqinile, ama-auger bits amade namafushane angasetshenziswa ukwelapha. Ngemva kokukhululeka, shintsha i-drill barrel ukuze uqhubeke nokubhoboza. Uma kuqhathaniswa nemishini evamile, ine-torque enkulu ejikelezayo, ingalungiswa ngokuzenzakalelayo ngokwezimo zokwakheka, i-WOB enkulu futhi kulula ukuyilawula.

4. Ikhwalithi ephezulu yokwakha izinqwaba

Ukuphazamiseka kwe-stratum kuncane, isikhumba sodaka sodonga olugcina izinto sincane, kanti udonga lwembobo olwakhiwe luqinile, okusiza ekwandiseni ukungqubuzana ohlangothini lwenqwaba nokuqinisekisa amandla okuthwala umklamo wesisekelo senqwaba. Kunodaka oluncane phansi komgodi, okulula ukuhlanza umgodi nokwandisa amandla okuthwala umkhawulo wenqwaba.

5. Ukungcoliswa kwemvelo okuncane

Iumshini wokubhoboza ojikelezayokuyibhobo yodaka eyomile noma engajikelezi, okudinga udaka oluncane. Ngakho-ke, indawo yokwakha ihlanzekile futhi icocekile futhi ayinangcolisi emvelweni. Ngesikhathi esifanayo, imishini inokudlidliza okuncane nomsindo ophansi.
