Isizinda Somhlangano Wokubhekwa Komgodi Wesisekelo Wephrojekthi Yokunwetshwa Kwesikhumulo Sezindiza sase-Pudong Isigaba IV
Bangaphezu kuka-100 abantu ababukele iqembu elithi "obukayo"
SEMW TRD, DMP indlela
Kuphrojekthi enkulu yomgodi wesisekelo ojulile eChina
NgoMeyi 10, 2023, "i-TAD/DMP Technology Exchange and Observation Activity of Pudong Airport Phase IV Expansion Project" yabanjwa kahle endaweni Yephrojekthi Yokunwetshwa Kwesikhumulo Sezindiza Samazwe Ngamazwe Se-Pudong.
Lo mhlangano wokubuka nokushintshisana ubusingathwe yiKomidi Lochwepheshe Bemishini Ye-Rock and Soil ye-Shanghai Mechanics Society, i-Huajian Group Shanghai Underground Space and Engineering Design Research Institute, i-Shanghai Machinery Construction Group Co., Ltd., i-Shanghai Yuanfeng Underground Engineering Technology Co., Ltd., kanye ne-Shanghai Engineering Machinery Co., Ltd. babambe iqhaza ekuhlanganiseni inhlangano. Abantu abangaphezu kwe-100 abavela kunhlolovo nokuklama, ukwakhiwa, izikhungo zocwaningo lwesayensi, amanyuvesi, amabhizinisi ezobuchwepheshe bokwakha namanye amayunithi babuthana eduze kobuchwepheshe obusha obubili bendlela yokwakha ye-TAD eyakhiwe ngaphambili isakhiwo esibiyelwe kanye nendlela yokwakha ye-DMP inqwaba yokuxuba ukuphazamiseka okuncane kwedijithali, kusukela kumklamo, Ukwakhiwa kanye nezinye izici zokuhwebelana kwezobuchwepheshe, izingxoxo kanye nokubhekwa kokwakhiwa kwezindlela ezintsha zokwakha.
Iphrojekthi enkulu yesisekelo esijulile e-China
Ingqikithi yendawo yomgodi wesisekelo wephrojekthi yokunwetshwa yeSigaba IV se-Pudong International Airport icishe ibe ngu-340,000 m2, ukujula okujwayelekile kokumba kucishe kube ngu-18.6-30.7 m, kanti ukujula okukhulu kokumba kucishe kube ngamamitha angama-36.7. Njengamanje iphrojekthi enkulu yomgodi ojulile e-China. Eduze komgodi wesisekelo, kunezinto zokuvikela ezizwelayo njengendawo yokulungisa, isikhungo samandla, kanye nolayini we-MRT ongasemoyeni. Ngesikhathi esifanayo, kunezingqimba eziningi ezixhunyanisiwe ezixhunywe emanzini angaphansi komhlaba asakazwa ongqimbeni olujulile lwesayithi, futhi ukwehla okukhulu kwamanzi avalelwe phakathi nesikhathi sokumba kufinyelele ku-30m. Ubunjiniyela bomgodi wesisekelo buyinkimbinkimbi, futhi ukuwohloka nokulawulwa kwamanzi okuvalekile kunzima.
Kuphrojekthi yomgodi wesisekelo, udonga olungaphansi komhlaba lwe-diaphragm oluhlanganiswe nendlela yokwakhiwa kodonga lukasimende olujulile nokulingana kwenhlabathi lusetshenziselwa ukumisa ikhethini elingangenwa amanzi, ukuhlanganiswa kodonga lwenqwaba, indlela yokwakha ye-TAD isakhiwo esivalekile esenziwe ngaphambili, ipayipi elicindezelwe ngaphambili. isakhiwo senqwaba ebiyelwe, inhlanganisela yensimbi ehlanganisiwe Uchungechunge lobuchwepheshe obusha obuluhlaza, okonga amandla nobungane nemvelo obufana nokusekela, i-ultra-high jet grouting, kanye nendlela yokwakha ye-DMP inqwaba yokuxuba ukuphazamiseka okuncane kwedijithali.
Dala ngokubambisana futhi wabelane ngezindlela ezintsha zokwakha kanye nobuchwepheshe obusha
Ku-ajenda yokuqala yomhlangano, okokuqala, u-Song Qingjun, isekela likanjiniyela omkhulu we-Shanghai Underground Space and Engineering Design Institute ye-Huajian Group, kanye no-Wang Boyang, unjiniyela wephrojekthi ye-Shanghai Machinery Construction Group Co., Ltd., ngokulandelana kwabo, bachaza umsebenzi owenziwe phansi. ubuchwepheshe bodonga lwe-diaphragm yendlela yokwakha ye-TAD, isimiso sendlela yokwakha ye-TAD kanye nombiko womhlangano uzokwenziwa ngezici zezici, ukukhethwa kwemishini, ubuchwepheshe bokwakha, ukuthuthukiswa kwendlela yokwakha nokunye.
Indlela yokwakha ye-TAD iyindlela yokwakha yodonga lwe-diaphragm olungaphansi komsele. Le ndlela yokwakha iwukufaka iphaneli yodonga eyakhiwe ngokhonkolo eqinisiwe ene-mortise ene-prestressed kanye nendlela ye-tenon {lock buckle} phakathi nodonga lwe-diaphragm olungaphansi komhlaba olunqunyiwe lwe-canal-cut ukuze lwakhe udonga lwe-diaphragm olungaphansi komhlaba olwakhelwe ngaphambili. Uma kuqhathaniswa nenqubo yendabuko yokwakhiwa kodonga lwe-diaphragm engaphansi komhlaba, Indlela yokwakha ye-TAD inezinzuzo zokuthatha indawo encane, ukuguquguquka okuqinile, isikhathi esifushane sokwakha, nokuvikelwa kwemvelo.
Shanghai Engineering Machinery Co., Ltd., Zhejiang Jitong Ground and Air Construction Technology Co., Ltd., Zhejiang University Binhai and Urban Geotechnical Engineering Research Center, Zhejiang Architectural Design and Research Institute, Zhejiang University of Science and Technology, kanye ne-Jianhua Building Materials (I-China) yenze ukubambisana okujulile kocwaningo lwemboni-yenyuvesi, yenza ubudlelwano bomphakathi obuhlelekile ekubalweni kwethiyori yendlela yokwakha ye-TAD, ukulungiswa kwephaneli yodonga, ukukhiqizwa kwemishini, njll., futhi kwakha indlela entsha yokwakha yokwakha umgodi wesisekelo. indawo ebiyelwe.
I-ajenda yesibili yomhlangano: UDkt. Li Qing we-Shanghai Underground Space and Engineering Design Research Institute ye-Huajian Group wenze umbiko womhlangano mayelana nobuchwepheshe benqwaba ye-digital micro-disturbance mixing yendlela yokwakha ye-DMP.
I-Digital micro-disturbance mixing pile (indlela yokwakha ye-DMP) yamukela umshini wenqwaba ye-DMP-I yedijithali ye-micro-disturbance mixing pile ekhethekile ye-Shanggong Machinery, futhi isebenzisa uhlelo lokulawula ukwakhiwa kwedijithali ukwenza ukulawula ukwakhiwa okuzenzakalelayo. I-slurry negesi okukhishwa ethekwini le-grouting (air) kusika inhlabathi ndawonye, futhi kuxube ngokulinganayo usimende namanye ama-ejenti okwelapha nenhlabathi ukuze kwakhe inqwaba enamandla athile nokungangenisi. Ngokulawula okuzenzakalelayo kokucindezela kwangaphakathi kanye ne-multi-channel Ukukhishwa kwe-slurry kanye nokukhipha ipayipi lokubhoboza elimise okukhethekile kuqaphela ukuphazamiseka okuncane kwenhlabathi ezungeze inqwaba phakathi nayo yonke inqubo yokubunjwa kwenqwaba, ebizwa ngokuthi i-DMP. indlela.
I-DMP-I digital micro-disturbance mixing pile machine (imishini yendlela yokwakha ye-DMP) iwumshini omusha wokwakha wedijithali wokuxuba inqwaba yomshini othuthukiswe ngokuhlanganyela yi-SEMW kanye namabhizinisi asekhaya aziwayo, izikhungo namanyuvesi, ikakhulukazi ukuxazulula inqwaba ngesikhathi ukwakhiwa kwezinqwaba zokuxuba zendabuko. Ukungalingani kancane, izinga eliphansi lokwaziswa, okunzima ukulawula izinga lokwakha, inhlabathi eshintshayo eyengeziwe, ukuphazamiseka okukhulu kokwakhiwa, ukusebenza kahle kokwakheka kwenqwaba nezinye izinkinga. Imishini yamukela ubuchwepheshe bokwakhiwa kwedijithali, enezici zokuphepha nokuthembeka okuphezulu, izinga eliphezulu lenqwaba, ukuphazamiseka okuncane endaweni ezungezile, nomphumela wokwakha ophezulu. Ngokuhlela indawo yenqwaba ye-GPS, ububanzi benqwaba bungama-850mm, kanti ukujula okuphezulu kokwakha kungafinyelela ku-45m. Ukumelana ngesikhathi sokuxuba kungathuthukisa ukufana kokuxuba komhlabathi kasimende kanye nekhwalithi yenqwaba. Imishini ayikwazi ukwengeza kuphela izindwani zokusika njengoba kudingekile, ivimbele ubumba ekunamatheleni epayipini lokubhoboza bese yenza amabhola odaka, futhi inciphise ukuphazamiseka ekubunjweni, kodwa futhi inomklamo okhethekile wamathuluzi okumba kanye nemishini yokusekela, kanye nokuma kwenqwaba. ingalawulwa ku-1/300. Ukusebenza kahle kusobala.
I-SEMW izibophezele ekuthuthukiseni nasekwakheni ukwakhiwa kwendawo engaphansi komhlaba kanye nokucwaninga kobuchwepheshe bokwakha okuhlobene, futhi izibophezele ekunikezeni amakhasimende izixazululo eziphelele zezisekelo ezingaphansi komhlaba, ukusiza ukwakhiwa kwengqalasizinda yedolobha kazwelonke, ukunamathela njalo kumqondo "wezinsizakalo zobungcweti, ukudala value" Amakhasimende athuthuka ndawonye. Imishini ye-Shanggong izosebenzisa ukunqwabelana kwayo okujulile emkhakheni wemishini yenqwaba ukuze ihlangabezane ngokugcwele nezidingo zamakhasimende zokwakha, inikeze amakhasimende izinsiza ezichwepheshile, futhi idale inani.
