Muva nje, i-Tyhen Founday's Backy Kr300s ephansi ye-rotary dilting rig ibamba iqhaza ekwakhiweni kwe-Guangzhou-Baiyun District JingGuang High-Speed Rail Line 5 Project.
Njengohlelo lokuhambisa abagibeli lwabagibeli lwe-Guangzhou's Urbar Rail System, Isiteshi saseBaiyun yisizinda sokuqala esisezingeni elikhulu sakhiwe ngokuhambisana nemibono yokuhlela ehlanganisiwe ye-Hub ehlanganisiwe yaseGuangzhou. Iphrojekthi ngokuyinhloko ifaka phakathi ukwakhiwa kwesiteshi esisha seGuangzhou Baiyun, kanye nentuthuko yezindawo ezihlobene ne-Dalang Bus Seartion Depot kanye nemigqa yesitimela exhuma. Iphrojekthi ihlelelwe ukuqedwa ngo-2023.
I-KR300ES ephansi yekhanda ejikelezayo yokushayela i-rig e-Guangzhou Heal-Speed Railey Pile Pile Dilege ye-1000mm, ukujula kwenqwaba, ukugcwaliswa kwendawo yokuchitha, okulula ukuwa, okulula ukuwa, ama-silttone e-silt. Inhlabathi engenhla ye-bacfill enomgodi we-sand Bucket bese ucishe ube ngamamitha ayi-5 ngaphansi kwe-tube. Ngemuva kokushaya ungqimba lwesihlabathi, udaka oluwugqinsi luyalungiswa ukuvikela ikhasi lamanzi. Faka idwala elithambekele, bujule bese ulihlanza ngebhakede lesihlabathi. Uma kwenzeka ukuvuvukala kwe-slurry emhumeni omncane we-karst, lokho kungukukhuliswa kwesikhumba, bese uqhubeka nokushayela ngemuva kokuqina usimende. I-KR300ES ephansi ye-Headroom Rotary Drilling Rig (ukuphakama kwamamitha ayi-10,,9) ukwakhiwa kwamamitha ayi-11, ifakwe nge-300 kn. Inhloko enkulu yamandla ka-Trorque ka-M arocates isilinganiso esifanelekile sodaka ukuvikela udonga ukuxazulula ukwakhiwa kokwakhiwa okusheshayo namandla anamandla okuthuthukisa ukusebenza kwezokwakha kokungena kokwakha. Ixazulula kahle izinkinga ezihlangabezana nazo esikhaleni esincane, ububanzi obukhulu be-pile, ukujula okujulile nedwala elinzima. Amakhasimende wokwakha asheshayo futhi asebenze kahle enza imali, azuze abasebenzi bendawo abadumisayo.
I-KR300ES ephansi yokugoba i-Right isetshenziswa engxenyeni yokwakha yephrojekthi yokwakha ye-Guangzhou Speed-Speed Rail Project, lapho ububanzi be-pile buyi-1000mm, kanye nokujula kwenhliziyo kusuka kumamitha ayi-28 kuye kwangama-33. Izimo zezwe ziyinkimbinkimbi futhi zifaka izici ezahlukahlukene ezifana nenhlabathi egcwalisa kahle (ikakhulukazi izingqimba ezibunjiwe ezinamamitha ayi-3 kuye kwayi-6, zithambekele ekuweni kwesandwatho sasasilisa, kanye netshe lesiliva esiliva. Emhlabathini ongaphezulu we-bacfill, kusetshenziselwa ibhakede le-sand-scooping ukudala ama-casing azungeze amamitha ayi-5 ngaphansi kobuso.
Ngemuva kokufinyelela ungqimba lwesihlabathi, i-slurry emnyama ebanzi isetshenziselwa ukuvikela ukungena kwamanzi. Lapho uhlangabezana nezendlalelo zedwala, kusetshenziselwa umgqomo oyisisekelo ukungena ngaphakathi, kulandelwa ukusetshenziswa kwebhakede elivinjelwe ngesihlabathi ukususa okuqukethwe. Uma kwenzeka imithambo emincane noma ikhasimende, usimende ujova, futhi ukumba kuyaqhubeka ngemuva kokuthi usimende uqinisile.
I-KR300ES ephansi yokugoba i-Right ephakeme, enokuphakama kwamamitha ayi-10,9, isebenza ekuphakameni kokwakha kwamamitha ayi-11 futhi ifakwe ikhanda lamandla anamandla we-30000.m. Isetshenziswa ngesilinganiso esifanelekile sodaka se-slurry sokuvikelwa odongeni, ekhuluma nezinselelo zokusebenza ekwakheni kwesihlabathi kanye nokwanda kwezokwakha lapho ungena ezingxenyeni ze-rock. Le ring ixazulula kahle izingqinamba ezihlangabezana nazo ekwakhiweni, kufaka phakathi isikhala esilinganiselwe, ububanzi obukhulu be-pile, ukujula okukhulu, nokungena kwe-rock kuyinselele. Ijubane layo lokwakha eliphakeme kanye nokusebenza kahle kutholile ukudumisa okuvumayo kubasebenzi bendawo yokwakha, ekugcineni kuhlomula ikhasimende.
