Site of Foundation Pit Observation Meeting ya Pudong Airport Phase IV Expansion Project
Anthu opitilira 100 akuwonera gululi "owonera"
SEMW TRD, DMP njira
Mu ntchito yayikulu kwambiri ya dzenje lakuya ku China
Pa Meyi 10, 2023, "TAD/DMP Technology Exchange and Observation Activity of Pudong Airport Phase IV Expansion Project" idachitikira pamalo a Pudong International Airport Phase IV Expansion Project.
Kuwonera ndi kusinthanitsa msonkhanowu unachitikira ndi Rock and Soil Mechanics Professional Committee ya Shanghai Mechanics Society, Gulu la Huajian Shanghai Underground Space and Engineering Design Research Institute, Shanghai Machinery Construction Group Co., Ltd., Shanghai Yuanfeng Underground Engineering Technology Co., Ltd., ndi Shanghai Engineering Machinery Co., Ltd. adachita nawo mgwirizanowu. Anthu opitilira 100 ochokera ku kafukufuku ndi kamangidwe, zomangamanga, mabungwe ofufuza zasayansi, mayunivesite, mabizinesi aukadaulo omanga ndi magawo ena adasonkhana mozungulira matekinoloje awiri atsopano a TAD yomanga njira yopangira mpanda komanso njira yomanga ya DMP yosakanikirana ndi mulu wosakanikirana wa digito, kuchokera pamapangidwe, Zomangamanga ndi zina zakusinthana kwaukadaulo, zokambirana ndi kuyang'ana komanga kwa njira zatsopano zomangira.
Pulojekiti yayikulu kwambiri yakuzama maziko ku China
Dera lonse la dzenje la maziko a pulojekiti yakukulitsa ya Phase IV ya Pudong International Airport ndi pafupifupi 340,000 m2, kuya kwa mabwinja onse ndi pafupifupi 18.6-30.7 m, ndipo kuya kwake kwakukulu ndi pafupifupi 36.7 m. Pakali pano ndiye projekiti yayikulu kwambiri yakuzama maziko ku China. Pansi pa dzenje la maziko, pali zinthu zodzitchinjiriza monga malo okonzera, malo opangira mphamvu, ndi mzere wa airside MRT. Pa nthawi yomweyo, pali Mipikisano wosanjikiza interconnected anatsekeredwa aquifers anagawira mu lakuya wosanjikiza wa malo, ndi pazipita dontho la madzi otsekedwa pa nthawi yofukula anafika 30m. Umisiri wa dzenje la maziko ndizovuta, ndipo kupindika ndi kuwongolera madzi kumakhala kovuta.
Mu ntchito ya dzenje la maziko, khoma lapansi panthaka la diaphragm lophatikizana ndi njira yopangira simenti-yozama kwambiri komanso yofanana ndi dothi losakanikirana ndi khoma limagwiritsidwa ntchito kuyimitsa chinsalu chopanda madzi, kuphatikiza khoma la milu, njira yomanga ya TAD yokhazikika, chitoliro chokhazikika. kamangidwe ka mpanda wa milu, kuphatikiza zitsulo zosakanikirana Njira zatsopano zobiriwira, zopulumutsira mphamvu komanso zachilengedwe monga chithandizo, ultra-high pressure jet grouting, ndi njira yomangira ya DMP digital micro-disturbance mixing mulu.
Pangani limodzi ndikugawana njira zatsopano zomangira ndi matekinoloje atsopano
Pa ndondomeko yoyamba ya msonkhano, choyamba, Song Qingjun, wachiwiri kwa injiniya wamkulu wa Shanghai Underground Space and Engineering Design Institute of Huajian Group, ndi Wang Boyang, injiniya wa polojekiti ya Shanghai Machinery Construction Group Co., Ltd., motsatana anafotokoza mobisa Ukadaulo wa khoma la diaphragm wa njira yomangira ya TAD, mfundo ya njira yomanga ya TAD ndi Lipoti la msonkhano lidzapangidwa pazokhudza mawonekedwe, kusankha zida, ukadaulo womanga, kukonza njira yomanga ndi zina zotero.
Njira yomanga ya TAD ndi njira yomangira khoma la khoma la diaphragm pansi pa ngalande. Njira yomangira iyi ndikuyika khoma lolimba la konkriti lopangidwa kale lomwe lili ndi makina a prestressed mortise ndi tenon mechanism {lock buckle} pakati pa ngalande-yodula simenti-dothi diaphragm khoma kuti apange khoma la pansi pa nthaka la diaphragm. Poyerekeza ndi njira yomangira makhoma apansi panthaka, Njira yomanga ya TAD ili ndi ubwino wokhala ndi malo ochepa, kusinthasintha kwamphamvu, nthawi yochepa yomanga, komanso kuteteza chilengedwe.
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, ndi Jianhua Building Materials (China) achita mozama makampani-yunivesite-kafukufuku mgwirizano, Kuchita mwadongosolo ubale pagulu pa chiphunzitso mawerengedwe a njira TAD yomanga, khoma gulu kukonzekera, kupanga makina, etc., ndi kulenga njira yatsopano yomanga pomanga dzenje maziko mpanda.
Ndondomeko yachiwiri ya msonkhano: Dr. Li Qing wa Shanghai Underground Space and Engineering Design Research Institute of Huajian Group anapanga lipoti la msonkhano pa digito ya micro-disturbance mixing mulu teknoloji ya njira yomanga ya DMP.
Digital yaying'ono-zosokoneza kusanganikirana mulu (DMP yomanga njira) utenga DMP-I digito yaying'ono-zosokoneza kusakaniza mulu makina zida zapadera za Shanggong Machinery, ndipo amagwiritsa ntchito digito kulamulira dongosolo kulamulira ntchito yomanga basi. The slurry ndi mpweya kutulutsidwa ku doko grouting (mpweya) kudula nthaka pamodzi, ndi wogawana kusakaniza simenti ndi wothandizila ena kuchiritsa ndi nthaka kupanga mulu ndi zina mphamvu ndi impermeability. Kupyolera mu kuwongolera kwamphamvu kwa mkati ndi njira zambiri Kutulutsa kwa slurry ndi kutuluka kwa chitoliro chobowola chopangidwa mwapadera kumazindikira kusokonezeka pang'ono kwa dothi lozungulira muluwo panthawi yonse yopangira milu, yomwe imatchedwa DMP. njira.
DMP-I digito yaying'ono-zosokoneza kusakaniza mulu makina (DMP zomangamanga njira zida) ndi latsopano digito zomangamanga luso kusakaniza mulu pobowola makina opangidwa ndi SEMW ndi odziwika bwino mabizinesi apakhomo, masukulu, ndi mayunivesite, makamaka kuthetsa mulu thupi pa kumanga miyambo kusakaniza milu. Zosafanana pang'ono, mulingo wochepa wa chidziwitso, zovuta kuwongolera mtundu wa zomangamanga, nthaka yowonjezera, kusokonezeka kwakukulu kwa zomangamanga, kutsika kwa milu yomanga bwino ndi zovuta zina. Zidazi zimagwiritsa ntchito luso la zomangamanga la digito, lomwe liri ndi makhalidwe otetezeka kwambiri ndi odalirika, khalidwe lapamwamba la mulu, kusokoneza pang'ono m'madera ozungulira, komanso zomangamanga. Pogwiritsa ntchito mulu wa GPS, mulu wake ndi 850mm, ndipo kuya kwake kwakukulu kumatha kufika 45m. Kukaniza panthawi yosakaniza kungapangitse kusakaniza kufanana kwa dothi la simenti ndi khalidwe la mulu. Zida sizingangowonjezera masamba odula ngati pakufunika, kuteteza dongo kuti lisamamatire ku chitoliro chobowola ndikupanga mipira yamatope, komanso kuchepetsa kusokonezeka kwa mapangidwe, komanso kukhala ndi mapangidwe apadera a zida zobowola ndi zida zothandizira, komanso kukhazikika kwa muluwo. akhoza kulamulidwa pa 1/300. Kuchita bwino ndi zoonekeratu.
SEMW wadzipereka pa chitukuko ndi kumanga mobisa danga yomanga ndi okhudzana kafukufuku luso zomangamanga, ndipo wadzipereka kupereka makasitomala ndi mayankho wonse kwa maziko mobisa, kuthandiza pomanga zomangamanga m'tauni dziko, nthawi zonse kutsatira mfundo ya "akatswiri ntchito, kulenga value" Makasitomala amakula limodzi. Shanggong Machinery, monga nthawi zonse, idzagwiritsa ntchito kudzikundikira kwake kozama m'munda wamakina mulu kuti ikwaniritse zosowa za makasitomala, kupereka ntchito zamaluso kwa makasitomala, ndikupanga phindu.
