中文Izinsuku ezimbili nobusuku obubili bokwakhiwa okuqhubekayo, inselele yokusebenza okuqhubekayo phesheya kwezilwandle ngaphansi kwezimo ezinzima, ugu lwaseBohai lubhala udumo olunciphile, i-Chengdao Oilfield ithwala ngesibindi umthwalo wemfanelo osindayo, ihlobisa "umdwebo kawoyela omuhle" olwandle... Eminyakeni yamuva nje , ngokukhiqizwa kukawoyela ongahluziwe we-Shengli Offshore Chengdao Oilfield uyaqhubeka nokwanda, kanye namaphrojekthi amakhulu engqalasizinda asogwini ayavela. Phakathi kwazo, isando se-SEMW H260MT hydraulic piling besilokhu sihamba phambili ekwakhiweni ukuze kuqinisekiswe inqubekelaphambili eqhubekayo yokwakhiwa kwephrojekthi.
Ngo-Agasti, emanzini angashoni kakhulu eningizimu yoLwandle i-Bohai eDolobheni laseDongying, esifundazweni saseShandong,SEMWngokuzimela uthuthukise isando sokuhlanganisa i-nitrogen esisebenza kabili esisebenza ku-hydraulic i-H260MT, esaqeda ngempumelelo i-CB208 yeqembu le-Chengbei block 208 yephrojekthi yokwakha umthamo e-Chengdao Oilfield, i-Shengli Oilfield Construction yamasethi angama-24 ezinqwaba zamapayipi ensimbi endaweni yesikhulumi.
Lo msebenzi wenziwa ngabakwaSinopec Shengli Oil Construction. Indawo yenqwaba yesikhulumi seqembu lomthombo ihlelwe njengoba kukhonjisiwe esithombeni esingezansi. Izinqwaba zamapayipi ensimbi ezinhlangothini zombili zesikhulumi ziyizikhuphukeli zokumba uwoyela ngasogwini lolwandle. Ububanzi benqwaba bungu-660mm kanti ubude benqwaba bungu-79.75m. Ngemva kokuqedwa kokwakhiwa, ukujula kwenqwaba odakeni kungu-60m. Ngenxa yezinguquko zedizayini, ubude benqwaba yesikhuphukeli bukhuphuke ukusuka cishe ku-60m kuya cishe ku-80m, kanti isando sikadizili i-D138 esasihlongozwe ekuqaleni asikwazanga ukuhlangabezana nezidingo zokwakha. Isando esisebenza ngogesi se-H260MT senkampani yethu sinenzuzo enkulu yesilinganiso samandla/ubuningi, esihlangabezana nezidingo zomklami futhi silwela ukubhekana nomsebenzi onzima.
Kubikwa ukuthi inqwaba yamapayipi ensimbi yale phrojekthi isebenzisa indlela yokuxhuma inqwaba esizeni, cishe 20m/section. Izinqwaba ezimbili zokuqala zifakwa enqwabeni ngesando sokudlidliza. Isando se-H260MT se-hydraulic yenkampani yethu yenza ukwakhiwa kokungena kwezinqwaba ezimbili zokugcina ezinobude obungama-40m.
Ukwakhiwa kwengxenye yesithathu yenqwaba kuhlanganisa isikhathi esisizayo njengezinqwaba. Isikhathi esijwayelekile sokuba inqwaba ngayinye ingene engqumbini cishe imizuzu engama-40, amandla ahlabayo acishe abe ngu-100 ~ 180kJ, imvamisa yokusebenza ngu-26BPM, futhi isilinganiso senani lokushayelwa ngesando cishe izikhathi ezingama-800. . Ukwakhiwa okuqhubekayo kwezinqwaba ze-24 ezinhlangothini zombili kuzoqedwa ngemva kwamahora angaba ngu-30 (kuhlanganise nesikhathi sokuhambisa umkhumbi).
Ngemuva kokuthi ukuxhumeka kwenqwaba sekuqediwe, ngesikhathi sokwakhiwa kwesigaba sesine sezinqwaba, amandla omthelela wesando se-hydraulic angaba ngu-200 ~ 230kJ, imvamisa yokusebenza imayelana ne-22 ~ 26BPM, isikhathi sokwakhiwa kwenqwaba eyodwa cishe ngama-60 ~ Imizuzu engama-90, futhi inani lokushaywa kwesando cishe imizuzu engama-60 ~ 90. 800 ~ 1500 izando, lapho 6~9m ukungena kuncane kakhulu. Ngemva kwezinsuku ezi-2 nobusuku obu-2 bokwakha okuqhubekayo, umsebenzi wokwakha wamaqembu amabili ezinqwaba ezingu-24 ekugcineni waqedwa.
Ukwengeza, izinqwaba ezi-4 eziyinhloko ze-φ1200 nobude be-104.669m beplatifomu zakhiwe yi-IHC S500, futhi ukulungiswa kwesando esisebenza ngamanzi kwaqedwa yinkampani yethu.
Kungokokuqala ukuthi isando esisebenza ngogesi i-H260MT siqedele ukwakhiwa kwezinqwaba zamapayipi ensimbi azacile ngaphansi kwezimo eziyinkimbinkimbi ngemva kokuphothula ukwakhiwa kwezinqwaba ze-viaduct u-Shanghai Tongji Road ekupheleni kuka-2020. Ngalokhu kwakhiwa, i-H260MT imelane nenselelo eqhubekayo ukusebenza ngaphansi kwezimo ezinzima futhi kuye kwanconywa kakhulu ngumsebenzisi.
Ukwazi ukubamba iqhaza kumaphrojekthi amaningi amakhulu nakanjani kusekelwe ngokuqinile ubuchwepheshe obusezingeni eliphezulu. I-SEMW HMT yochungechunge lwezando zokuhlanganisa i-hydraulic luhlanganisa ucwaningo olujulile kanye nemvula yobuchwepheshe yamakhasimende lapho idingeka khona, ihlanganisa inani lobuchwepheshe obunemba okuphezulu kanye nomzimba owodwa, futhi ibe nokusebenza okunamandla kakhulu. Asetshenziswa kumabhuloho awela ulwandle, amapulatifomu okumba uwoyela ngasogwini lolwandle, amapulazi omoya asogwini lolwandle, amaphrojekthi amakhulu afana namatheminali anamanzi ajulile kanye nokwakhiwa kweziqhingi zokwenziwa olwandle enze kahle.
I-HMT hydraulic pile isando umkhiqizoisingeniso:
I-HMT series hydraulic piling hammers izando ezisebenza kahle kakhulu eziklanywe futhi zakhiwe yi-SEMW, ukusebenza kwayo okuyinhloko sekufinyelele ezingeni elithuthukile lamazwe ngamazwe. Uma kuqhathaniswa nesando senqwaba yedizili yomphongolo, isando senqwaba ye-hydraulic sinezici zomsindo ophansi, akukho ntuthu enamafutha, ukusebenza kahle kokudluliswa kwamandla, ubude besikhathi eside benqwaba yamandla okucwila emjikelezweni ngamunye wokusebenza, nokulawula kalula amandla ashayayo. Lolu chungechunge lwemikhiqizo lunezinhlobonhlobo zokusetshenziswa, ukulawulwa okuphezulu, ukusebenza kahle okuphezulu kokwakhiwa, ukuvikelwa kwemvelo nokonga amandla kanye nokuthembeka okuphezulu, futhi zombili zinezinqwaba ezithambekele nezinye izindlela zokusebenza.
Lolu chungechunge lwezando zokuhlanganisa i-hydraulic luwuhlobo olusebenza kabili. Ngemuva kokuthi umgogodla wesando womthelela uphakanyiselwe endaweni ephakeme enqunywe kusengaphambili ngedivayisi esebenza ngamanzi, ngaphansi kwesenzo esihlanganisiwe samandla adonsela phansi namandla anwebekayo e-nitrogen ecindezelwe, kutholwa isivinini somthelela esiseqophelweni eliphezulu, kanye nomthelela wesando sokuhlanganisa amanzi ngcono. amandla.
Uchungechunge lwe-HMT izando zokuhlanganisa i-hydraulic zihambisana nethiyori yesando esindayo yesando esilula. Zibonakala ngesisindo somgogodla wesando esincane, isivinini somthelela esiphezulu, amandla omthelela omkhulu, futhi zilungele ukushayela inqwaba yensimbi. Ilungele amaphrojekthi amakhulu anjengamabhuloho awela ulwandle, izinkundla zokumba uwoyela ngasogwini lolwandle, amapulazi omoya aphesheya kwezilwandle, amachweba anamanzi ajulile kanye neziqhingi zokwenziwa zasolwandle, futhi inethemba elibanzi kakhulu lemakethe.
Izinzuzo zokwakha:
◆ Umsindo omncane, ukungcola okuncane, ukonga ugesi, ukuvikelwa kwemvelo nokwethembeka;
◆ Izinga eliphakeme lokuzenzakalelayo, uhlelo oluzinzile, ukusebenza okulula kanye nezinga eliphansi lokuhluleka;
◆ Ukuthembeka okuhle kwesistimu nokusebenza okuhle kakhulu kwemishini;
◆ Ukucushwa okuguquguqukayo, ububanzi bohlelo lokusebenza, ukulungiswa okuqinile nekhono lokulawula.
