Te waahi o te Hui Tirohanga Pit Foundation o Pudong Airport Phase IV Expansion Project
Neke atu i te 100 nga taangata e matakitaki ana i te roopu "kaitaki"
SEMW TRD, tikanga DMP
I roto i te kaupapa poka hohonu nui rawa atu i Haina
I te Mei 10, 2023, ko te "TAD/DMP Hangarau Whakawhiti me te Matakitaki Mahi mo te Pudong Airport Phase IV Expansion Project" i tino whakahaerehia i te waahi o Pudong International Airport Phase IV Expansion Project.
Ko tenei hui tirohanga me te whakawhitiwhiti i whakahaerehia e te Komiti Ngaio Toka me te Whenua Mechanics o te Shanghai Mechanics Society, Huajian Group Shanghai Underground Space and Engineering Design Research Institute, Shanghai Machinery Construction Group Co., Ltd., Shanghai Yuanfeng Underground Engineering Technology Co., Ltd., me Shanghai Engineering Machinery Co., Ltd. i uru ki te whakahaere-tahi.Neke atu i te 100 nga taangata mai i te rangahau me te hoahoa, te hanga, nga whare rangahau pūtaiao, nga whare wananga, nga umanga hangarau hanga me etahi atu waahanga i huihui a tawhio noa i nga hangarau hou e rua o te tikanga hanga TAD te hanganga o te waahi kua oti te hanga me te DMP te tikanga hanga mamati moroiti-raruraru whakaranu puranga, mai i te hoahoa, Ko te hanga me etahi atu ahuatanga o te whakawhitiwhiti hangarau, nga korerorero me te tirotiro hanga i nga tikanga hanga hou.
Ko te kaupapa poka hohonu nui rawa atu i Haina
Ko te tapeke o te rua turanga o te kaupapa whakawhanui Wāhanga IV o Pudong International Airport e tata ana ki te 340,000 m2, ko te hohonutanga o te keri whanui kei te 18.6-30.7 m, me te hohonu o te keri keri mo te 36.7 m.I tenei wa ko te kaupapa poka hohonu nui rawa atu i Haina.Huri noa i te rua turanga, he mea whakamarumaru tairongo penei i te waahi tiaki, te pokapu hiko, me te raina MRT i te taha o te rangi.I te wa ano, he maha nga paparanga-a-whare e hono ana i nga aquifers herea kua tohatohahia ki te paparanga hohonu o te waahi, me te nui o te maturuturu o te wai i roto i te waa keri ka eke ki te 30m.He uaua te hangahanga o te rua turanga, he uaua te whakarereketanga me te whakahaere i te wai.
I roto i te kaupapa poka turanga, ko te pakitara o raro o te whenua kua honoa me te tino-hohonu me te rite-te matotoru o te raima-te-te-te-te-te-te-te-te-a-te-te-te-te-te-te-te-te-te-te-taapiri o te hanga pakitara ka whakamahia hei aukati i te arai-wai, te whakaurunga puranga-taiepa, te tikanga hanga TAD i hangaia i mua i te hanganga taiepa, te putorino o mua. te hanganga o te kopae putu, te huinga maitai huinga He raupapa o nga hangarau hou kaakaariki, penapena hiko me te pai ki te taiao penei i te tautoko, te pehanga jet tino teitei, me te tikanga hanga DMP te puranga whakaranu moroiti moroiti.
Hanga tahi me te tiri i nga tikanga hanga hou me nga hangarau hou
I runga i te kaupapa tuatahi o te hui, tuatahi, ko Song Qingjun, te kaitoi rangatira tuarua o Shanghai Underground Space me te Engineering Design Institute o Huajian Group, me Wang Boyang, te miihini kaupapa o Shanghai Machinery Construction Group Co., Ltd., i whakamaramahia te hanga i raro i te whenua. hangarau taiepa diaphragm o te tikanga hanga TAD, te kaupapa o te tikanga hanga TAD me Ko te ripoata hui ka mahia mo nga ahuatanga o nga ahuatanga, te whiriwhiringa taputapu, te hangarau hanga, te whakapai ake i te tikanga hanga me etahi atu.
Ko te tikanga hanga TAD ko te tikanga hanga o te taiapa taiapa i raro i te whenua.Ko tenei tikanga hanga ko te whakauru i tetahi papa raima kua oti te hanga i mua me te moti me te anga o mua {lock buckle} ki waenganui o te pakitara diaphragm oneone kua tapahia he awa hei hanga i te pakitara diaphragm raro whenua.Ka whakatauritea ki te tikanga hanga pakitara o raro o raro o te whenua, Ko te tikanga hanga TAD he pai ake te iti o te noho mokowhiti, te kaha urutau, te wa hanga poto, me te tiaki taiao.
Shanghai Engineering Machinery Co., Ltd., Zhejiang Jitong Ground me Air Construction Technology Co., Ltd., Zhejiang University Binhai me Urban Geotechnical Engineering Research Center, Zhejiang Architectural Design and Research Institute, Zhejiang University of Science and Technology, me Jianhua Building Materials (Haina) kua kawea i roto i-hohonu ahumahi-wānanga-rangahau mahi tahi, Kawea i roto i whanaungatanga nahanaha tūmatanui i runga i te tātai ariā o te tikanga hanga TAD, te whakarite röpü taiepa, hanga mihini, me ētahi atu, me te hanga i te tikanga hanga hou mo te hanga poka turanga. kohanga.
Ko te kaupapa tuarua o te hui: Ko Takuta Li Qing o Shanghai Underground Space and Engineering Design Research Institute o Huajian Group i hanga he ripoata hui mo te hangarau moroiti-raruraru whakararu i te puranga hangarau o te tikanga hanga DMP.
Mamati moroiti-raruraru whakararu i te puranga (te tikanga hanga DMP) tango i te DMP-I mamati moroiti-whakararuraru whakararu i te pile mīhini taputapu motuhake o Shanggong Machinery, me te whakamahi i te pūnaha mana hanga mamati ki te kawe i te mana hanga aunoa.Ko te slurry me te hau i marere mai i te tauranga grouting (hau) ka tapahia te oneone, ka whakakotahi i te sima me etahi atu rongoa ki te oneone kia hangai he puranga me te kaha me te koretake.Na roto i te whakahaere aunoa o te pehanga o roto me te hongere-maha Ko te rere o te slurry me te ruha o te putorino putunga motuhake ka mohio ki te raruraru iti o te oneone huri noa i te puranga i te wa katoa o te hanganga o te puranga, e kiia ana ko te DMP tikanga.
Ko te DMP-I mamati moroiti-raruraru whakararu i te putu miihini (DMP hanga taputapu tikanga) he hangarau hanga matihiko hou te whakakotahi i te miihini keri puranga i hangaia e te SEMW me nga umanga a-whare rongonui, nga whare wananga, me nga whare wananga, ko te nuinga ki te whakaoti i te tinana puranga i te waa te hanga i nga puranga whakaranu tawhito.He iti noa, he iti te taumata o te whakamohiotanga, he uaua ki te whakahaere i te kounga o te hanga, he nui ake te oneone whakakapi, he nui te whakararuraru i te hanga, he iti te pai o te hanga puranga me etahi atu raru.Ko nga taputapu e whakamahi ana i te hangarau hanga mamati, he ahuatanga o te tino haumaru me te pono, te kounga teitei o te puranga, te iti o te raruraru i te taiao a tawhio noa, me te kaha o te hanga.Na roto i te whakatakotoranga o te tuunga puranga GPS, he 850mm te diameter o te puranga, a ka taea te hohonu o te hangahanga ki te 45m.Ko te aukati i te wa whakaranu ka taea te whakapai ake i te whakakotahitanga o te ranunga o te oneone sima me te kounga o te puranga.Kaore e taea e nga taputapu te taapiri i nga mata tapahi ka hiahiatia, ka aukati i te paru kia piri ki te putorino putunga me te hanga i nga poi paru, me te whakaiti i te whakararuraru ki te hanganga, engari he hoahoa motuhake ano mo nga taputapu keri me nga taputapu tautoko, me te poutū o te puranga. ka taea te whakahaere i te 1/300.Ka kitea te kaha.
Kei te kaha a SEMW ki te whakawhanaketanga me te hanga o nga waahi o raro o te whenua me te rangahau hangarau hangahanga e pa ana, me te whakapau kaha ki te whakarato i nga kaihoko ki nga otinga katoa mo nga turanga o raro o te whenua, me te awhina i te hanganga o nga hanganga taone nui o te motu, me te piri tonu ki te kaupapa o te "ratonga ngaio, te hanga. uara" Ka whanake tahi nga kaihoko.Ka whakamahia e Shanggong Miihini, i nga wa katoa, te whakaemi hohonu i roto i nga miihini puranga ki te whakatutuki i nga hiahia hanga o nga kaihoko, whakarato ratonga ngaio mo nga kaihoko, me te hanga uara.
