Kutshanje, iTyhen Foundation's low headroom KR300ES rotary drilling rig ithathe inxaxheba ekwakhiweni kweprojekthi yeSithili saseGuangzhou-Baiyun iJingguang High-Speed Rail Line 5.
Njengendawo yokuthuthwa kwabakhweli yenkqubo kaloliwe yasedolophini yaseGuangzhou, iSikhululo saseBaiyun siyindawo yokuqala enkulu eyakhiwe ngokuhambelana neengqikelelo zale mihla zokucwangcisa ihabhu yezothutho eGuangzhou.Le projekthi ibandakanya ikakhulu ukwakhiwa kweSikhululo esitsha saseGuangzhou Baiyun, kunye nophuhliso lwezixhobo ezinxulumeneyo ezifana neDalang Bus Maintenance Depot kunye nomzila kaloliwe odibanisayo.Le projekthi icwangciselwe ukugqitywa ngo-2023.
I-KR300ES Igumbi elisezantsi legumbi lokumba elijikelezayo kwindawo yolwakhiwo lweprojekthi kaloliwe enesantya esiphezulu se-1000mm, ubunzulu bemfumba phakathi kwe-28 ~ 33 yeemitha, iimeko zejoloji zintsonkothile: ngokuyintloko ukuzaliswa (ngokukodwa ukubunjwa kokubuyisela umva, amasuntswana enkunkuma yokwakha mkhulu), udongwe olunentlenga. , intlenga yentlenga (iimitha ezi-3-6, umngxuma kulula ukudilika), igrabile, ilitye lentlabathi elinemozulu enamandla, ilitye lentlabathi.Umhlaba ongaphezulu wokuzalisa ngasemva kunye nomngxuma webhakethi yesanti kwaye emva koko malunga neemitha ezi-5 phantsi kombhobho.Emva kokubetha umaleko wesanti, udaka olungqindilili luyahlengahlengiswa ukuze kuthintelwe ukuphuma kwamanzi.Ngenisa ilitye elichongekileyo, ugrumbe nzulu uze ulilobe nge emele yesanti.Kwimeko yokuvuza kodaka kumqolomba omncinci wekarst, oko kukuthi i-backfill yesamente, kwaye uqhubeke nokugrumba emva kokuqina kwesamente.I-KR300ES Kwigumbi elisezantsi le-rotary drilling rig (ubude beemitha ezili-10.9) ubude bokwakha obuziimitha ezili-11, luxhotyiswe nge-300 kN.Intloko yamandla e-torque enkulu ye-m inikezela umlinganiselo ofanelekileyo wodaka ukukhusela udonga ukusombulula ukwakhiwa kokwakhiwa kwesanti ekhawulezayo kunye namandla anamandla okuphucula ukusebenza kakuhle kokwakhiwa kokungena kwamatye.Isombulula ngokugqibeleleyo iingxaki ezidibene nendawo encinci, ubukhulu bemfumba enkulu, ubunzulu obunzulu kunye nelitye elinzima.Ukwakhiwa ngokukhawuleza kunye nokusebenza kakuhle kwabathengi benza imali, baphumelele indumiso yabasebenzi kwindawo yokwakha.
I-KR300ES ye-headroom low rotary drilling rig isetyenziswa kwindawo yokwakha yeprojekthi kaloliwe ebaleka ngesantya esiphezulu sase-Guangzhou, apho ububanzi bengqumba buyi-1000mm, kwaye ubunzulu bengqumba busuka kuma-28 ukuya kuma-33 eemitha.Iimeko zejoloji zintsonkothile kwaye zibandakanya izinto ezahlukeneyo ezinjengomhlaba wokuzalisa ngezinto ezahlukeneyo (ingakumbi umaleko ozaliswe ngasemva onamasuntswana enkunkuma yokwakha), udongwe oluyintlenga, isanti enentlenga (ukusuka kwi-3 ukuya kwi-6 yeemitha, ethanda ukudilika), iileya zegrabile ezingqukuva, intlenga enemozulu embi kakhulu. ilitye lentlabathi, kunye nelitye lentlabathi eliphakathi kwimozulu ephakathi.Kumhlaba ongaphezulu ozele ngasemva, i-emele yokugalela isanti isetyenziselwa ukwenza i-casing malunga neemitha ezi-5 ngaphantsi komhlaba.
Emva kokufikelela kumaleko esanti, udaka oluludaka olungqindilili lusetyenziselwa ukuthintela ukungena kwamanzi.Xa udibana neengqimba zamatye, i-core barrel isetyenziselwa ukungena, ilandelwa kukusetyenziswa kwebhakethi yokukhupha isanti ukususa izinto.Kwimeko yemingxuma emincinci okanye i-seepage, i-samente ijojowe, kwaye ukugaya kuyaqhubeka emva kokuba i-samente iqinisiwe.
I-KR300ES ephantsi kwe-headroom rotary drilling rig, enobude obuziimitha ezili-10.9, isebenza kumphakamo wokwakha weemitha ezili-11 kwaye ixhotyiswe ngentloko yamandla e-torque ye-300kN.m enamandla.Isetyenziswa ngomlinganiselo ofanelekileyo wodaka lodaka lokukhusela udonga, ukujongana nemingeni yokusebenza kwimizobo yesanti equkuqelayo kunye nokwandisa ukusebenza kakuhle kolwakhiwo xa kungenwa kumaleko amatye.Le rig isombulula ngokugqibeleleyo imiba ekuye kwahlangatyezwana nayo kulwakhiwo, kuquka indawo enyiniweyo, ingqumba enkulu yobubanzi, ubunzulu obubalulekileyo, kunye nomngeni wokungena kwamatye.Isantya esiphezulu sokwakha kunye nokusebenza kakuhle kuzuze indumiso ngamxhelo mnye kubasebenzi bendawo yokwakha, ekugqibeleni kuxhamle umthengi.
