Isixazululo Sendawo Eyimpumputhe Yomshini Wokubamba Amapayipi


Ngomhla ziyi-19 kuNhlaba, 2021, umshini wokuqala omkhulu emhlabeni wonke wokugqekeza wamapayipi aqinile angama-rectangular "Tianfei 1" walethwa ungaxhunyiwe ku-inthanethi. Lo mshini wokuntshontsha amapayipi uzosetshenziswa kuphrojekthi exhumene nojantshi wesitimela esiteshini sikaloliwe iPutian. Kuphinde kube iphrojekthi yokuqala enzima eShayina lapho ukugqekezwa kwamapayipi amakhulu angama-rectangular amaningi kudlula ujantshi osebenzayo ngesikhathi esisodwa.
Ingxenye yokumba ye-"Tianfei 1" ingu-12.6m ububanzi no-7.65m ukuphakama. Yamukela ukwakheka okuhlanganisiwe kwezendlalelo ezimbili, ezintathu zangaphambili, ezine zangemuva nama-Cutterheads ayisikhombisa. Izindawo ezisikwayo zama-Cutterheads eziseduze ziyaphambana, izinga lokumbiwa kwengxenye lingama-95%, futhi linamandla okuphuka amadwala nokusebenza kahle komhubhe. Ingakwazi ukumba ezindaweni eziqinile zamatshe aqinile kanye nomhlangano we-rock strata ongu-100MPa, ngokuphazamiseka okuncane ku-stratum, Ukuqinisekisa ukuthi ubungozi bokuphepha bokuwela Ngaphansi kukaloliwe okhona wase-Hangzhou Shenzhen uyalawuleka.
Inkinga
Kuyaqondwa ukuthi uma kuqhathaniswa nokwakhiwa kwesihlangu, umhubhe ongunxande onokwakhiwa kwepayipi lokugqekeza ungenza ukusetshenziswa kwendawo ngokuphumelelayo kunomhubhe oyindilinga ngaphansi kwendawo efanayo ephambanayo; Ngaphezu kwalokho, uma isetshenziselwa ukwakhiwa kwe-Underpass njengabahamba ngezinyawo kanye nemoto, asikho isidingo sokwenza inqubo yokufaka phansi, engagcini nje kuphela isikhathi, kodwa futhi inciphisa izindleko zephrojekthi. Ngesikhathi esifanayo, umshini we-jacking we-hard rock uzohlinzeka ngolwazi olubalulekile ekwakhiweni kwemigudu yamatshe aqinile angama-rectangular emhlabeni jikelele.
Kodwa-ke, ekuqaleni komklamo wephrojekthi, umshini wokuthungatha ipayipi onesakhiwo sekhanda le-multi cutter unenkinga yokugaya indawo eyimpumputhe ekwakhiweni kwesakhiwo. Uma i-rock mass kulezi zindawo eziyizimpumputhe ayikwazi ukugaywa ngokuhambisanayo, ngeke nje ithinte yonke inqubo yokuthungatha umshini wokuthungatha ipayipi, kodwa futhi ibangele izindleko ezengeziwe ngenxa yokugaya kanye nokumbiwa kwesibili.

Isixazululo
Ngakho-ke, abaholi be-China Railway bathintana nenkampani ye-Yichen ngethemba lokuthi i-Yichen inganikeza isisombululo senkinga yokugaya indawo eyimpumputhe yomshini wokuthungatha ipayipi. Kulokhu, i-Yichen yaklama futhi yakhiqiza amamojula amabili okugaya kumakhasimende ngokusebenzisa amandla ayo e-R & D kanye neminyaka eminingi yokuhlangenwe nakho okusebenzayo, okuxazulule ngempumelelo inkinga yendawo eyimpumputhe yokugaya.
Siyibiza ngokuthi igobolondo lokusika izigubhu. Igobolondo layo kanye nekhanda lokugaya kuyisakhiwo esihlanganisiwe. Ijikeleza ngesikhathi esifanayo lapho isebenza. I-spiral blade ikulungele ukuthutha imfucuza embiwe iyiswe ngemuva. Baxazulule indawo eyimpumputhe yokugaya emaphethelweni angaphezulu naphansi omshini wokuntshontsha amapayipi we-"Tianfei 1".
Esinye isigubhu sokugaya, esifakwe ezinhlangothini zombili zomshini wokuthungatha amapayipi "Tianfei 1". Isetshenziselwa ukugaya kanye nokumba inqwaba yamadwala endaweni eyimpumputhe ezinhlangothini zombili zomshini wokuthungatha amapayipi.

"I-Tianfei 1" umshini wokuthungatha ipayipi ungaqedela ukugaya nokumbiwa kwendawo yonke yesikwele ngesikhathi esifanayo ngemva kokuba ifakwe igobolondo lokusika imigqomo kanye nesigubhu sokugaya esiklanywe futhi senziwa ngokwezifiso yi-Yichen. Isixazulule ngokuphelele inkinga yendawo eyimpumputhe yokwakha, yanciphisa kakhulu izindleko zokwakha, futhi yabeka isisekelo esiqinile sokuphothulwa kwephrojekthi yesiteshi sikaloliwe iPutian ngesikhathi esimisiwe.
