中文Ngomhla ziyi-15 kuMasingana, ukuqeqeshwa kobuchwepheshe bokuntshontsha amapayipi angenantambo ka-2024 kanye nesifundo sokuqeqeshwa kokutholwa kwamapayipi esixhaswe yiPipeline Trenchless Crossing Technology Professional Committee yase-China Petroleum Engineering and Construction Association saphothulwa ngempumelelo e-Shanghai Construction Management Vocational and Technical College. Abantu abavela emanzini, emiseleni, emanzini emvula Bangaphezu kuka-50 abaphathi bephrojekthi, abaklami, abaphathi, ochwepheshe bonjiniyela, nabacwaningi besayensi ababambe iqhaza ekwakhiweni nasekulungiseni amapayipi ahlukahlukene angaphansi komhlaba (amanethiwekhi) kanye namaphaseji abanzi afana nogesi, ukushisisa, isikhathi eside- uwoyela negesi ebangeni, nokongiwa kwamanzi kubambe iqhaza ekuqeqeshweni futhi kwakwazi kahle ngokusebenzisa Ubuchwepheshe bokufunda obuhlobene nokugqekezwa kwamapayipi angenawo amanzi kanye namakhono okubona amapayipi ukuze kuthuthukiswe izinga lobuchwepheshe kanye namakhono angokoqobo wamayunithi ahlobene angenawo amanzi kanye nokunciphisa izingozi zokwakha.
Eminyakeni yamuva nje, insimu yokwakhiwa kwamapayipi angaphansi komhlaba ikhule ngokushesha. Ukuze kusetshenziswe ngokugcwele imithombo yendawo engaphansi komhlaba yasemadolobheni futhi kuqinisekiswe intuthuko esimeme yedolobha, bayanda amapayipi afakwa kusetshenziswa izindlela ezinjengokugejwa kwamapayipi okungenamisele. Njengoba izidingo zokwakhiwa konjiniyela ziqhubeka nokuba ngcono, ukumba ngezandla ngobuchwepheshe basemuva kanye nokusebenza kabi kabi kuyaqedwa kancane kancane. Ubuchwepheshe be-trenchless bungowokuqala ukukhuthazwa emadolobheni amakhulu naphakathi nendawo, okuzophinde kuvule indawo yemakethe enkulu esikhathini esizayo.
Njengomhleli ngokubambisana, iShanggong Machinery yayibambe iqhaza ngokujulile kulokhu kuqeqeshwa. Kusukela uchungechunge lwe-PJR ye-Shanggong Machinery's PJR rigs micro pipe jacking rigs kanye ne-PIT series press-in shaft pipe rolling machine yethulwa emakethe, bathole idumela elikhulu ngokusebenza, ukwethembeka, ukuphepha nokusebenza kahle. Izinzuzo zayo eziphelele zokuncintisana kwezocansi nezinye izici ngokushesha zagqama emakethe futhi zazuza umusa osabalele kubasebenzisi yonke indawo.
I-Central Economic Work Conference yango-2021 yagcizelela ngokuqondile ukuthi phakathi nesikhathi "soHlelo Lweminyaka Emihlanu", ukulungiswa nokwakhiwa kwamapayipi kufanele kuthathwe njengomsebenzi wengqalasizinda obalulekile, futhi kudinga ngokusobala ukuthi kusheshiswe ukuvuselelwa nokulungiswa kwamapayipi agugile emadolobheni. UMnyango ukhiphe umgomo wokuthi imigwaqo yasemadolobheni ayivunyelwe ukumbiwa ngokuthanda kwakho. Indlela "evulekile futhi egujwe" yokungcwaba amapayipi isiphelelwe yisikhathi. Ubuchwepheshe "obuhlasela kancane" ithrendi nendlela yokubekwa kwamapayipi. Ubuchwepheshe be-Trenchless ubuchwepheshe "obungena kancane" bomzila wamapayipi. Intuthuko yesikhathi esizayo Amathemba abanzi.
Umuntu oqaphela isimo uhlakaniphile, futhi obonayo uhlakaniphile. I-SEMW izoqhubeka nokwenza imikhiqizo ngendlela esezingeni eliphansi, inqobe izithiyo zobuchwepheshe, ihlinzeke ngezinsizakalo ezizinikele, iqhubekele phambili futhi iqhudelane emakethe futhi, iphikelele ekujuleni phambili emakethe, ihlangabezane nezidingo zamakhasimende eduze, qhubeka. ukwenza izinto ezintsha zobuchwepheshe, nokusebenzisa ithuba lokuchuma kwemboni ukusebenza nawo wonke umuntu. Funa intuthuko!
PJR uchungechunge microukubhoboza ipayipiumshini:
I-Micro pipe jacking isetshenziswa kakhulu ekuhlinzekeni kwamanzi namapayipi endle, amapayipi egatsha amapayipi egesi, amandla kagesi, ezokuxhumana kanye namanye amapayipi. Indlela yokwakha ipayipi iwukuba uqale ufake umshini wokubhoboza ipayipi endaweni esebenza kahle, uqale ubhoboze ipayipi lokubhoboza i-auger emhlabathini eduze ne-axis emaphakathi yepayipi ukuze uthole umhlahlandlela wepayipi, bese usebenzisa i-helical reaming drill bit ukuze wandise. umgodi kububanzi bepayipi obuklanyelwe. Ipayipi elizofakwa liqinile. Ngokulandela i-auger bit, ipayipi lamathuluzi limba ungqimba lomhlabathi ngaphansi kokuphonswa kwesilinda samafutha esikhulu. Umhlabathi ombiwe ulahlwa yiphampu yenhlabathi noma i-screw conveyor noma ukhishwa ngendlela yodaka ngepompo yodaka ngepayipi. Ngemva kokuqhubekela phambili kwesigaba sepayipi , i-jack eyinhloko ihoxiswa, enye ingxenye yepayipi iphakanyisiwe, futhi i-jacking iyaqhubeka. Phinda le nqubo kuze kube yilapho ipayipi selibekiwe. Ngemuva kokuthi ukufakwa kwepayipi sekuqediwe, ipayipi lamathuluzi liyaphakanyiswa kusuka ku-shaft eyamukelayo kuya phezulu.
Izici zokusebenza:
■ Ukwakhiwa kuhlanganisa indawo encane, akulimazi imigwaqo ekhona, futhi kunomthelela omncane esiminyaminyeni;
■ Umsindo omncane wokwakha, udaka oluphumayo oluncane, umthelela omncane endaweni ezungezile, nokuphepha okuphezulu ekwakhiweni;
■ Ukunemba okuphezulu kokwakhiwa, ubuchwepheshe obuphambili, isivinini sokwakha esisheshayo kanye nezindleko zokwakha eziphansi.
Amapharamitha wokusebenza
Umshini wokuhlikihla amapayipi ochungechunge lwe-PIT:
Indlela yokwakha ye-PIT isebenzisa umshini wokuzulazula wepayipi we-rocking-in shaft ukuze ucindezele i-casing yangaphandle ekhethekile (isilinda sensimbi) emhlabathini ngenkathi uyinyakazisa. Umgodi wesisekelo wakhiwe ngokumba ingxenye yesigxobo sensimbi esigcinayo. Uma kuqhathaniswa namanye amaphrojekthi okusekela inqwaba yamashidi ensimbi, indlela yokwakha yokudlidliza, umsindo ophansi, ukonga amandla nokuvikelwa kwemvelo kugqamisa ubuchwepheshe obuhle kakhulu bokuphepha, umnotho nokusebenza kahle.
Uchungechunge lwe-PIT umshini wokugoqa wamapayipi ocindezelwa ku-shaft uwumshini omusha wokumba i-casing owenziwe ngokuzimela yi-Shanggong Machinery ngesisekelo sokwethula, ukugaya kanye nokumunca ubuchwepheshe obuphambili bangaphandle. Ihlanganisa ukulawulwa kwe-electromechanical kanye ne-hydraulic. Lo mshini unemisebenzi ebanzi, uyavumelana nezimo futhi awusindi, futhi uhlanganisa imisebenzi yamamodeli ahlukahlukene ekhaya naphesheya. Inezici zokulawula isivinini esiningi kanye ne-torque, ukulungiswa okuqondile okuzenzakalelayo, ukulawulwa kwe-cutter head force control, i-remote wire control, njll. Kulula ukusebenza, akukho msindo, ukudlidliza okuphansi, nokusebenza okuphezulu. Iphakeme futhi inokwethenjelwa.
Ububanzi besicelo:
■ Izisekelo zesitimela esihamba ngaphansi komhlaba, umgodi ojulile wesisekelo ovale izinqwaba ezingenelanayo, izinqwaba zokwakhiwa kabusha kwedolobha kanye nezinqwaba zokususa izithiyo, izinqwaba ezibhokile zojantshi, amachweba, imigwaqo namabhuloho, imifula, amachibi, izakhiwo eziphakeme, ukwakhiwa kwamandla kagesi kanye nokongiwa kwamanzi, kanye nesithukuthezi senhloso ekhethekile. izinqwaba;
■ Ithatha i-casing egcwele futhi ingakhiwa eduze nezakhiwo ezikhona. Ilungele ukusebenza ezindaweni zasemadolobheni.
Izici zokusebenza:
Ukwakhiwa okuphephile nokusebenzayo
■ Abasebenzi akudingeki basebenze emgodini wesisekelo, yonke imisebenzi yenziwa phansi, iqinisekisa ukuphepha kwabasebenzi; phakathi nenqubo yokwakha, i-casing yensimbi ingagcina ngokuphumelelayo inhlabathi futhi ivikele udonga, iqede ngokuphumelelayo izingozi ezifihliwe zokuwa komhlabathi kanye nokucwiliswa kwesisekelo;
■ Izinto ezisetshenziswayo ziyaguquguquka futhi zilula ngesisindo futhi zingasetshenziselwa ukwakha okuvamile ngisho nasezindaweni eziwumngcingo emigwaqeni. Ngisho nasezisekelweni ezingenakho ukuzimela, asikho isidingo sezinqubo ezisizayo ezifana nomjovo wezinto ezibonakalayo futhi kufanelekile ukwakhiwa ezinhlotsheni ezahlukene zezisekelo.
Akukho ukudlidliza, umsindo ophansi
I-casing yensimbi icindezelwa ngaphakathi futhi ikhishwe ngokusebenza kwe-hydraulic cylinder, engakwazi ukufeza ukudlidliza nomsindo ophansi.
Ukusebenza okuphezulu kuqinisekisa ukunemba kokwakhiwa
■ Uhlelo lokusebenza oluhlakaniphile lusiza abasebenzi bokwakha baqonde ngokushesha ukuthi izinto zokusebenza zisebenza kanjani;
■ Imishini ingaqinisekisa ukuma kwe-casing yensimbi ngohlelo lokulawula oluthuthukisiwe, inikeze amandla okucindezela azinzile kuma-strata ahlukene, futhi iqinisekise ukwakhiwa okunembayo okuphezulu.
