中文Ngomhla we-15 kaJanuwari, i-2024 i-2024 i-trenchless pipe jacking technology kunye nekhosi yoqeqesho lokubona imibhobho exhaswa yiKomiti ye-Pipeline Trenchless Crossing Technology Professional ye-China Petroleum Engineering and Construction Association yaqukunjelwa ngempumelelo kwi-Shanghai Construction Management Vocational and Technical College.Abantu abaphuma kunikezelo lwamanzi, imibhobho yamanzi, amanzi emvula Ngaphezu kwabasebenzi abangama-50 bolawulo lweprojekthi, abayili, abaphathi, iingcali zobunjineli, kunye nabaphandi benzululwazi ababandakanyekayo ekwakhiweni nasekuhlaziyeni imibhobho eyahlukeneyo engaphantsi komhlaba (uthungelwano) kunye neepaseji zemibhobho ezibanzi ezifana nombane, ukufudumeza, ixesha elide Umgama we-oyile negesi, kunye nokugcinwa kwamanzi kuthathe inxaxheba kuqeqesho kwaye kwaphumelela ngokufunda iiTekhnoloji ezinxulumene nokugqogqa kombhobho okungenamingxuma kunye nezakhono zokubona imibhobho ukuphucula inqanaba lobugcisa kunye nobuchule obusebenzayo beeyunithi ezinxulumene ne-trenchless kunye nokunciphisa imingcipheko yokwakha.
Kwiminyaka yakutshanje, intsimi yokwakhiwa kwemibhobho engaphantsi komhlaba iye yanda ngokukhawuleza.Ukuze kusetyenziswe ngokupheleleyo ubutyebi besithuba esingaphantsi komhlaba esiphantsi komhlaba kunye nokuqinisekisa uphuhliso oluzinzileyo lwesixeko, ngakumbi nangakumbi imibhobho efakwayo kusetyenziswa iindlela ezinjengokugqobhoza kwemibhobho engenamithanjana.Njengoko iimfuno zokwakha zobunjineli ziqhubeleka nokuphucuka, ukugrumba ngezandla ngobuchwephesha obungasemva kunye nokusebenza kakubi kuyapheliswa ngokuthe ngcembe.Itekhnoloji yeTrenchless yeyokuqala ukukhuthazwa kwizixeko ezikhulu neziphakathi, eziya kuthi zivule ngakumbi indawo yentengiso kwixesha elizayo.
Njengomququzeleli odibeneyo, iShanggong Machinery yayibandakanyeke ngokunzulu kolu qeqesho.Ukusukela oko Shanggong Machinery kaThixo PJR series micro umbhobho jacking rigs kunye PIT series press-in shaft umbhobho ukuqengqeleka oomatshini eziqengqelekayo zaziswa emarikeni, baye bafumana udumo olukhulu ngokwemigaqo yokusebenza, ukuthembeka, ukhuseleko kunye nokusebenza kakuhle.Iingenelo zayo ezibanzi zokukhuphisana ngokwesondo kunye neminye imiba yakhawuleza yavela kwintengiso kwaye yazuza inkoliseko exhaphakileyo kubasebenzisi kuyo yonke indawo.
INkomfa yoMsebenzi wezoQoqosho ePhakathi ka-2021 yagxininisa ngokukodwa ukuba “kwiSicwangciso seMinyaka emiHlanu ye-14”, ukulungiswa kwemibhobho nolwakhiwo kufuneka kuthathwe njengeprojekthi yeziseko ezingundoqo ezibalulekileyo, yaye kufuneke ngokucacileyo ukuba kukhawuleziswe uhlaziyo nokuhlaziywa kwemibhobho esele iguga ekukhuleni kwabantu ezidolophini.ISebe likhuphe umgaqo-nkqubo wokuba iindlela zasezidolophini azivumelekanga ukuba zigrunjwe ngokuthanda kwazo.Indlela "evulekileyo kunye negutted" yokungcwaba imibhobho iphelelwe lixesha.Itekhnoloji "engenabuncinci" bubuchwephesha yindlela kunye nesalathiso sokubekwa kwemibhobho.Itekhnoloji yeTrenchless "yitekhnoloji ehlaselayo encinci" kwimibhobho.Uphuhliso lwexesha elizayo Amathemba abanzi.
Umntu oqwalasela imeko usisilumko, yaye oyibonayo imeko usisilumko.I-SEMW iya kuqhubeka nokwenza iimveliso ngendlela ephantsi ukuya emhlabeni, yoyisa imiqobo yobugcisa, ibonelela ngeenkonzo ezizinikeleyo, iqhubela phambili kwaye ikhuphisane kwimarike kwakhona, iqhubeke nokungena nzulu kumgca wangaphambili wemarike, ihlangabezane ngokusondeleyo neemfuno zabathengi, qhubeka. ukwenza iteknoloji entsha, kwaye uthathe ithuba lokuchuma kweshishini ukusebenza nomntu wonke.Funa uphuhliso!
PJR series microukugrumba umbhobhoisixhobo:
I-Micro pipe jacking isetyenziswa ngokubanzi kunikezelo lwamanzi kunye nemibhobho yogutyulo, imibhobho yesebe lemibhobho yegesi, amandla ombane, unxibelelwano kunye neminye imibhobho.Indlela yokwakha umbhobho wokugqobhoza kukuqala ukufakela i-drill jacking drill kwindawo esebenzayo, kuqala ugrumbe umbhobho we-auger drill emhlabeni ecaleni kwe-axis esembindini yombhobho ukumisela isikhokelo sombhobho, kwaye emva koko usebenzise i-helical reaming drill bit ukwandisa. umngxuma kwidayamitha yombhobho oyiliweyo.Umbhobho oza kufakwa uqinile.Ukulandela i-auger bit, umbhobho wesixhobo ugrumba kumaleko womhlaba phantsi kokutyhalwa kwe-cylinder yeoli engundoqo.Umhlaba ogrunjiweyo ukhutshwa ngempompo yomhlaba okanye isikhonkwane sokuhambisa isikrufu okanye ukhutshelwe ngendlela yodaka ngempompo yodaka ngombhobho.Emva kokuqhubela phambili icandelo lombhobho , i-jack enkulu ihoxiswa, elinye icandelo lombhobho liphakanyiswa, kwaye i-jacking iyaqhubeka.Phinda le nkqubo de kube kubekwe umbhobho.Emva kokuba ukufakwa kombhobho kugqityiwe, umbhobho wesixhobo uphakanyiswa kwi-shaft yokufumana phezulu.
Iimpawu zokusebenza:
■ Ulwakhiwo lugubungela indawo encinci, alonakalisi iindlela esele lukhona, kwaye lunempembelelo encinane kwizithuthi;
■ Ingxolo yolwakhiwo oluphantsi, ukukhutshwa kodaka okuncinci, impembelelo encinci kwindalo esingqongileyo, kunye nokhuseleko oluphezulu lolwakhiwo;
■ Ukuchaneka okuphezulu kolwakhiwo, ubuchwepheshe obuphezulu, isantya sokwakha ngokukhawuleza kunye neendleko eziphantsi zokwakha.
Iiparamitha zokusebenza
Uluhlu lwe-PIT cinezela kumatshini wokuhlikihla umbhobho we-shaft:
Indlela yokwakha ye-PIT isebenzisa umatshini wokurola we-rocking press-in shaft ukuze ucinezele i-casing yangaphandle ekhethekileyo (i-cylinder yentsimbi) emhlabeni ngelixa uyishukumisa.Umgodi wesiseko wakhiwe ngokugrumba inxalenye yentsimbi yokugcina intsimbi.Xa kuthelekiswa nezinye iiprojekthi zenkxaso yemfumba yentsimbi, indlela yokwakha yokungcangcazela, ingxolo ephantsi, ukonga amandla kunye nokukhuselwa kwendalo kuqaqambisa iteknoloji ebalaseleyo yokhuseleko, uqoqosho kunye nokusebenza kakuhle.
Uluhlu lwe-PIT lokucofa umbhobho wokuqengqeleka kweshaft ngumatshini omtsha wokomba ozimeleyo ophuhliswe nguomatshini baseShanggong ngesiseko sokwazisa, ukwetyisa kunye nokufunxa itekhnoloji ephezulu yangaphandle.Idibanisa ulawulo lwe-electromechanical kunye ne-hydraulic.Lo matshini unemisebenzi ebanzi, ubhetyebhetye kwaye ukhaphukhaphu, kwaye ugubungela imisebenzi yeemodeli ezahlukeneyo ekhaya nakwamanye amazwe.Uneempawu zesantya ezininzi kunye nokulawulwa kwe-torque, ukulungelelaniswa okuzenzekelayo ngokuzenzekelayo, ukulawulwa kwamandla entloko ye-cutter, ukulawula ucingo olukude, njl.Iphezulu kwaye ithembekile.
Ubungakanani besicelo:
■ Iziseko zikaloliwe ohamba ngaphantsi komhlaba, isiseko somngxuma onzulu ovalele iingqumba ezidityanisiweyo, iingqumba zokwakhiwa ngokutsha kwedolophu kunye neengqumba zokususa imiqobo, iimfumba ezikruqukileyo zomzila kaloliwe, amazibuko, iindlela kunye neebhulorho, imilambo, amachibi, izakhiwo eziphakamileyo, umbane wamanzi nolwakhiwo lokugcinwa kwamanzi, kunye nokudikwa ngenjongo eyodwa. iimfumba;
■ Yamkela i-casing epheleleyo kwaye inokwakhiwa kufutshane nezakhiwo esele zikhona.Ilungele ngokukodwa ukusebenza kwiindawo zasezidolophini.
Iimpawu zokusebenza:
Ulwakhiwo olukhuselekileyo nolusebenzayo
■ Abasebenzi akufuneki basebenze kumgodi wesiseko, yonke imisebenzi yenziwa phantsi, iqinisekisa ngokufanelekileyo ukhuseleko lwabasebenzi;ngexesha lenkqubo yokwakha, i-casing yensimbi inokugcina ngokufanelekileyo umhlaba kwaye ikhusele udonga, ikhuphe ngokufanelekileyo iingozi ezifihliweyo zokuwa komhlaba kunye nokucwiliswa kwesiseko;
■ Isixhobo sibhetyebhetye kwaye sikhaphukhaphu ngobunzima kwaye sinokusetyenziselwa ulwakhiwo oluqhelekileyo nakwizithuba ezimxinwa ezindleleni.Nakwiziseko ezingenakho ukuzithemba, akukho mfuneko yeenkqubo ezincedisayo ezifana nenaliti yezinto eziphathekayo kwaye ifanelekile ukwakhiwa kwiintlobo ezahlukeneyo zeziseko.
Akukho ngcangcazelo, ingxolo ephantsi
I-casing yensimbi icinezelwe kwaye ikhutshwe ngokusebenza kwe-hydraulic cylinder, engakwazi ukufikelela ngaphandle kokungcangcazela kunye nengxolo ephantsi.
Ukusebenza okuphezulu kuqinisekisa ukuchaneka kolwakhiwo
■ Inkqubo ekrelekrele yokusebenza inceda abasebenzi bokwakha baqonde ngokukhawuleza indlela esisebenza ngayo isixhobo;
■ Izixhobo zinokuqinisekisa ukuqina kwentsimbi yentsimbi ngokusebenzisa inkqubo yokulawula ephambili, ukubonelela ngokucofa okuzinzileyo kwi-strata eyahlukeneyo, kunye nokuqinisekisa ukwakhiwa okuchanekileyo.
