Kutshanje, i-tyhen yesiseko se-ny 300ider ye-ring right rig ethathe inxaxheba kulwakhiwo lwe-Guangzhou-Baiyin yesithili se-Gungguang Iprojekthi yeSantya seNdawo eyi-5.
Njengesithuthuthu sabekhweli se-hub yenkqubo kaGuangzhou's yase-Urland, isikhululo seBaisiy yindawo yokuqala enkulu eyakhiwe ngokungqinelana ne-HubHicetion yeHubHouse Cuangzhou. Le projekthi iquka ukwakhiwa kwesikhululo saseNew Guangzhou Baiy, kunye nophuhliso lwamaziko ahambelana noko njengendawo yokugcina i-Dalang kwaye aqhagamshela imizila kaloliwe. Iprojekthi icwangciselwe ukugqitywa ngo-2023.
I-KR300s ecocekileyo ye-rilar rig kwindawo yokwakha ye-Gile yePilay yePilay yePilay yePilay ye-1000mm, iimitha ezingama-33, i-slills, i-slills, i-slines, i-sliene sline. Umhlaba ongasemva we-backfill nge-sbacket hole kwaye malunga ne-5 yeemitha phantsi kwetyhubhu. Emva kokubetha ungqimba lwentlabathi, udaka olunzima luhlengahlengiswa ukuthintela iphepha lokuthintela amanzi. Ngenisa iLitye elityekele, hamba nzulu kwaye emva koko uyilondoloze ngebhakethi yesanti. Kwimeko yokufakelwa kwe-slurry kumqolomba omncinci wekarst, oko kukuseka umva, kwaye uqhubeke ukuqhuba emva kokuba isamente siyaziqinisa. I-KR300S E-Headroom Roterround i-rig (ukuphakama kweemitha ezili-10,9) ukuphakama kweemitha ezili-11, zixhotywe nge-300n KN. Intloko enkulu ye-torque ye-MALCEka umlinganiso ofanelekileyo wokukhusela udonga ukusombulula ukwakhiwa kwe-quicks kunye namandla anamandla okuphucula ukusebenza kwelitye. Isombulula ngokugqibeleleyo iingxaki ezihlanganisiweyo kwindawo encinci, ububanzi bezinto ezinkulu zepeyinti, ubunzulu obunzulu kunye nobunzima belitye. Ukwakha ngokukhawuleza kunye nabathengi abaziinqanaba eliphezulu benza imali, baphumelele indawo yokwakha indumiso.
The KR300ES low headroom rotary drilling rig is used in the construction site of the Guangzhou high-speed rail project, where the pile diameter is 1000mm, and the pile depth ranges from 28 to 33 meters. Iimeko zeJomological zintsonkothileyo kwaye zibandakanya izinto ezahlukeneyo ezinje ngomhlaba wokugqibela wokuzaliswa komhlaba (ukubuyela umva kwi-3 ukuya kwi-6 ukuya kwi-6 ukuya kwi-6 ukuya kwi-sling sandren, kunye nelitye elinesilika esine-silty le swillty switne. Kumhlaba ongasemva umqolo, ibhakethi lesanti lisetyenziselwa ukwenza i-cheng malunga ne-5 yeemitha ngaphantsi komphezulu.
Emva kokufikelela kwisanti yesanti, i-mud ye-mud ye-hid isetyenziselwa ukuthintela ukungena kwamanzi. Xa udibana nelitye, i-core barrel isetyenziselwa ukungena, ilandelwe kukusetyenziswa kwebhakethi yesanti ukususa umxholo. Kwimeko yeendawo ezincinci okanye i-bitpage, idini lesamente liyaphoswa, kwaye ukuqhuba kuyaqhubeka emva kokuba isamente iyemelele.
I-KR300s ecocekileyo ye-raterround ijikeleza i-rig, ekuphakameni kweemitha eziyi-10,9, isebenza kubude bokwakha ezi-11 zeemitha kwaye zixhotywe ngentloko engama-300kn.m. Isetyenziselwa i-Mud ye-Mud yoMdaka yoKhuseleko loLwandle, ukujongana nemiceli mngeni yokusebenza kwimozulu yesanti kunye nokwanda kokusebenza ngokwakha xa kungena kwilitye. Le rig isombulula ngokugqibeleleyo imiba equbisana nolwakhiwo, kubandakanya indawo encinci, ububanzi obukhulu, ubunzulu, kunye nokungeniswa kwelitye. Isantya sayo esiphezulu sokwakha kunye nokusebenza kakuhle kuye kwakufumene indumiso engamnandi kwi-Nations sakhiwo, ekugqibeleni sizuza umthengi.
Ixesha lokuposa: I-Oct-25 ukuya kwi-2023
