Indlela yokumba ye-Static kanye ne-Excengent Isingeniso

Indlela yokumba ye-tuli kanye ne-routing ukusebenzisa i-turling tulling kanye nendlela yokutshala inqwaba yokutshala, ukuxubana okujulile kokuxubana, okukugcina ukucaciswa okwenziwe ngentengo, okuthi ekugcineni ukucaciswa kwama-conkresser I-ConcRCREE PIPE PILES (PRHC) ihlanganiswe ekuhlanganiseni okuhlukahlukene ukuze ihlangabezane nezidingo zokwakhiwa, futhi zenziwa ngokuya ngokumba, ukunwetshwa okuphansi, ukukhishwa, ukufakwa kanye nezinye izinqubo. Indlela yokwakha ye-Pile Foundation. Ngenxa yezimpawu zendlela yokwakha yokushayela i-tuling kanye nenqwaba ye-routing, umzimba we-pile ungadlula kubahlaseli abahlukahlukene bezwe, futhi ububanzi be-pile bungama-500 ~ 1200mm. Njengamanje, ukujula kokwakha okuphezulu kungafinyelela kumamitha angama-85 ngaphansi komhlaba, futhi ukucwila kwe-pile yomshini owodwa kungafinyelela ngaphezu kwe-300m ngosuku, futhi inzuzo yezomnotho iphakeme. kwezinye izinhlobo zenqwaba.

1. Izici zendlela yokwakha

Ukukhishwa kwenhlabathi kwenhlabathi, akukho okudlidliza, umsindo ophansi; ukuxazulula izinkinga zokwakha zodaka lwendabuko olugcinayo umgodi odongeni oludongeni, ukulawulwa kwendlanzi, kanye nokukhishwa kwe-maud;

② Ubuchwepheshe obuhlukile bokunwebeka obuhlukile, ububanzi bokunwebeka obungaphansi buyi-1 ~,6 izikhathi ze-1

③ Fitlant inqwaba esetshenzisiwe kwi-borehole, futhi inhlabathi kasimende iqinisa ukwakha umzimba wenhlabathi eqinile eqinile, kanye ne-slurry yangaphandle inomphumela omkhulu wokuvikela emzimbeni wenqwaba;

Ukucindezelwa okuqinile okuqinile, ukungcola nokuvuselelwa komthwalo ovundlile;

Ngokusebenzisa izinhlobo ezahlukahlukene zezinqwaba ezinjengezinqwaba ze-bamboo kanye nezinqwaba eziqinisiwe, kanye namasu aphansi aphansi kanye namasu okuphuma, ukucindezela, ukudonswa, ukudonswa kanye nokuvundwa kwamandla okuthola izisekelo zenqwaba kwenziwa ngcono;

⑤ Ukulondolozwa kwamandla nokuvikelwa kwemvelo;

Qhathanisa nezinqwaba ezinesithukutheze ngaphansi kwezimo ezifanayo: Ukulondolozwa kwamanzi okwakha, ukonga amandla okulondolozwa kwama-40%, ukuncishiswa kwe-mud kunciphisa ama-70%, ukusebenza kahle kwe-10% ~ 20%;

Idizayini etholwe;

Ngokwezici zengcindezi zezinqwaba, izinhlobo ezahlukahlukene zezinqwaba zingahlanganiswa, kanjena:

Isimiso se-2.process

Inqubo eyakha umgodi yokuxuba ipayipi lokuxubha kanye ne-auger drill Pipe ekusebenzeni eyomile yamukelwa, umgodi uchithwa ngokuya ngokujula komklamo, futhi ukuphela kwenqwaba kuyavunyelwa ngokuya ngosayizi wokuklama (ububanzi nokuphakama). Ngemuva kokuthi i-REAME isiqediwe, i-Pile End Slurry Slurry kanye ne-slurry kasimende ezungeze inqwaba yenqwaba idonswa ngenkathi i-grouting. Ngemuva kokuqedwa kokudonswa kwemali, inqwaba ifakwe ezingeni lokuklama ngokuzenzisa kwesisindo senqwaba, kanye nethiphu yenqwaba kanye ne-slurry kasimende ezungeze inqwaba kuqinile, ukuze inqwaba, ithi inqwaba, i-pile pury kanye ne-slurry ezungeze inqwaba iqinile. Yakha umzimba bese wenza amandla ahlanganayo ndawonye.

3. Inqubo yokwakha

I-static drive kanye nendlela yokwenza inqwaba yokwakha ukusebenzisa i-RIG ekhethekile ye-SDP yokushayela izimbobo ngokuya ngezidingo zokwakhiwa. Phansi komgodi kutholwe ngokusho kobubanzi obuklanywe nokuphakama. Phakamisa ukumba, futhi ngemuva kokugcwaliswa kwe-grouting, kuncike ekuzitheni inqwaba yokufaka inqwaba ukugxilisa inqwaba ekuphakameni kwe-design, futhi kuqinisa inqwaba yenqwaba, ukuze inhlabathi ehlanganisiwe nenhlabathi eqinile ihlanganiswe. Umthamo we-Hearing of Piles utholwa ikakhulukazi nge-PILE side Frish kanye ne-Pile Tip Resistance. Indlela yokushayela ye-tuli kanye ne-mile yokwakha inyusa umthamo wethiphu yenqwaba ngokunwebeka phansi kwethiphu yenqwaba, futhi kwandise ukumelana kwesihlahla senqwaba ngokujova uCement Slurry esihlangothini esiphakeme senqwaba yenqwaba ebekiwe futhi uthuthukise umthamo wenqwaba yenqwaba ye-Pile.

Izinyathelo zokwakha:

Ukumba: ukumba isikhundla se-Rig, ukhetha ijubane lokumba elifanele ngokuya ngezimo zezwe, ngesikhathi senqubo yokumba, ukujova amanzi noma inhlanganisela ye-bentonite ngokuya ngezimo zomhlaba, zivikele udonga;

Ukunwetshwa okungezansi: Ngemuva kokuqedwa kwe-trimming, phansi kwenqwaba kuvulwa ukudonsa izimbobo ukwandisa i-wing ngokusebenzisa ubuchwepheshe obuhle kakhulu be-hydraulic, futhi phansi kunwetshwe ezingxenyeni zokwanda kwephiko. Nangedivaysi yokuphatha ukuqapha isimo sokunwebeka esingezansi ngesikhathi sangempela;

Umjovo we-Pile End Cement Slurry umjovo: Ngemuva kokuqedwa kokunwetshwa phansi, i-pule end slurry ifakwe kaninginingi futhi yehliswa ngesikhathi sokujova ukuze kuqinisekiswe ukuthi zonke izingxenye zokunwebeka zingenawo umfaniswano;

Umjovo we-cement slurry ezungeze inqwaba futhi ukhiphe umjovo we-slurry kasimende endaweni ye-pule ekugcineni, qala ukukhipha ipayipi elidonsa, ufake i-slurry ezungeze inqwaba bese uvuse kaninginingi;

Ukutshala inqwaba kanye nokulethwa kwenqwaba: Ngemuva kokuthi i-rig yokumba ikhipha wonke amapayipi okumba, qala ukutshala izinqwaba. Ngesikhathi senqubo yokutshala inqwaba, qapha nganoma isiphi isikhathi ukuqinisekisa ukugcwala kwenqwaba futhi uqinisekise ukujula kokutshala kwenqwaba;

Shift: Hambisa endaweni elandelayo yenqwaba bese uphinda izinyathelo ezingenhla;

Okwesine, ubukhulu bokusetshenziswa kwendlela yokwakha

Ufanelekile ukuhambisa ukungcola okuqondile, ama-pullout kanye nemithwalo evundlile;

② inhlabathi ehlanganayo, i-silt, inhlabathi enesihlabathi, ukugcwalisa inhlabathi, okuchotshoziwe (amatshe aqhekekile (amatshe amatshe anezimo eziyinkimbinkimbi zomhlaba, abahlangene abaningi, izimo zezulu, kanye noshintsho olukhulu kubulukhuni nokuthamba;

③Umba lapho kunezakhiwo (izakhiwo) noma amapayipi angaphansi komhlaba nezinye izikhungo zobunjiniyela eduze nendawo yokwakha, umphumela wenhlabathi wenhlabathi udinga ukulawulwa;

Ikhwalithi yenhlabathi enzima enzima ngezinqwaba ezinesithukutheze ukwakha izimbobo, ezinjengesihlabathi esikhulu kanye nabahlaseli be-Pebble noma inhlabathi e-silt enokuqukethwe okuphezulu komswakama (ukuvulwa komhlaba);

⑤ Ukujula kwe-stratum evunayo kuyahluka kakhulu, futhi kunzima ukwahlulela i-stratum; Isisekelo esithambile senhlabathi, isisekelo esingenayo stratum efanelekile;

 Kunezisekelo ezindala zezinqwaba ezingaphansi komhlaba kanye nongqimba lwe-slag lwamamitha angaphezu kuka-3 abuyiselwa phezu komhlaba.

I-5

I-static drive kanye nemishini yendlela ye-routing ikakhulukazi iyindlela yokwakha yokumba i-rig ye-pile. Ekuqaleni, yayisetshenziswa ngohlaka lwenqwaba yethrekhi yokwakha, edinga ukungezwa okuningi kwamapayipi okumba, kanye nokusebenza kokwakha kwakuphansi. Manje ifakwe kakhulu ngefreyimu ye-pile ephindwe kabili, futhi imingcele yokwakha emibili yokwakha imiswe ngasikhathi sinye. Ukushayela ngokuhlukile uma nje i-Pole isetshenziswa, ukujula kungafinyelela kuma-85m, okuthuthukisa kakhulu ukusebenza kwezokwakha.

Imishini yokushayela ye-tuli kanye ne-routing ye-gialing yamukela isoftware yokuphatha yokwakha ehlakaniphile ukuqapha inqubo yokwakha ngesikhathi sangempela ukuqinisekisa ikhwalithi yokwakha. Imininingwane ehlukahlukene yokwakha ibonakala ngokucacile kwisibonisi futhi igcinwe ngokuzenzakalelayo.

I-Drill Tight yamukela ubuchwepheshe bokunwebeka ongezansi kawoyela, ububanzi obungezansi bokunwebeka buyi-1 ~,6 izikhathi eziyi-1.6 zohlobo lokumba, kanye nokuphakama kokunwebeka okungezansi kunezikhathi ezi-3 zohlobo lokumba; Ngokusho kwezimo ezahlukahlukene zezwe lezomnotho, ukwakhiwa kungakhetha ukudonsa okujwayelekile noma ukumba okukhethekile;

I-Universal Drill Bit: Ilungele inhlabathi enesihlabathi

Ukushayela okukhethekile:

Eminyakeni yamuva nje, indlela yokumba ye-static dilling isetshenziswe kabanzi eShanghai, eNingbo, i-Hangzhou namadolobha awo azungezile, ukwakhiwa okwengeziwe kokwakhiwa kwenhliziyo, kanye nemininingwane yokwakha ehlobene nayo kanye namazinga ezobuchwepheshe nakho kwakhiwe ngokulandelana. Uhlobo olusha lwendlela yokwakha ye-pile eyisisekelo eluhlaza futhi enobungane, kunokwenza kahle ukwakhiwa okuphezulu kanye nomphumela omuhle wobumba, futhi kufanelekile ukukhushulwa okwengeziwe.
