Qhov chaw ntawm Foundation Pit Observation Lub Rooj Sib Tham ntawm Pudong Tshav Dav Hlau Phase IV Expansion Project
Ntau tshaj 100 tus neeg saib cov pab pawg "tus saib xyuas"
SEMW TRD, DMP method
Nyob rau hauv qhov loj tshaj plaws sib sib zog nqus foundation qhov project nyob rau hauv Tuam Tshoj
Thaum lub Tsib Hlis 10, 2023, "TAD/DMP Technology Exchange thiab Observation Activity ntawm Pudong Tshav Dav Hlau Phase IV Expansion Project" tau muaj nyob rau ntawm qhov chaw ntawm Pudong International Airport Phase IV Expansion Project.
Lub rooj sib tham thiab kev sib pauv no tau tuav los ntawm Pawg Neeg Ua Haujlwm Pob Zeb thiab Av Mechanics ntawm Shanghai Mechanics Society, Huajian Group Shanghai Underground Space thiab Engineering Design Research Institute, Shanghai Machinery Construction Group Co., Ltd., Shanghai Yuanfeng Underground Engineering Technology Co., Ltd., thiab Shanghai Engineering Machinery Co., Ltd. tau koom nrog kev koom tes. Ntau tshaj 100 tus neeg los ntawm kev tshawb fawb thiab tsim, kev tsim kho, kev tshawb fawb hauv tsev kawm ntawv, cov tsev kawm qib siab, kev tsim kho tshuab kev lag luam thiab lwm cov chav sib sau ua ke nyob ib ncig ntawm ob lub thev naus laus zis tshiab ntawm TAD kev tsim kho txheej txheem prefabricated enclosure qauv thiab DMP kev tsim kho txoj kev digital micro-kev cuam tshuam sib xyaw pawg, los ntawm kev tsim, Kev tsim kho thiab lwm yam ntawm kev sib pauv, kev sib tham thiab kev tsim kho kev soj ntsuam ntawm txoj kev tsim kho tshiab.
Qhov loj tshaj plaws sib sib zog nqus foundation qhov project nyob rau hauv Tuam Tshoj
Tag nrho cov cheeb tsam ntawm lub hauv paus qhov ntawm theem IV expansion project ntawm Pudong International tshav dav hlau yog hais txog 340,000 m2, lub dav excavation qhov tob yog hais txog 18.6-30.7 m, thiab qhov siab tshaj plaws excavation qhov tob yog hais txog 36.7 m. Tam sim no nws yog qhov loj tshaj plaws sib sib zog nqus hauv paus qhov project hauv Suav teb. Nyob ib ncig ntawm lub hauv paus hauv paus, muaj cov khoom tiv thaiv rhiab xws li thaj chaw tu, lub zog chaw, thiab cov kab hauv huab cua MRT. Nyob rau tib lub sijhawm, muaj ntau txheej txheej sib txuas sib txuas sib txuas hauv cov dej hauv qhov sib sib zog nqus ntawm qhov chaw, thiab qhov siab tshaj plaws ntawm cov dej kaw thaum lub sijhawm khawb mus txog 30m. Lub hauv paus pit engineering yog complex, thiab deformation thiab confined dej tswj yog nyuaj.
Nyob rau hauv lub hauv paus pit project, lub underground diaphragm phab ntsa ua ke nrog lub ultra-dav thiab sib npaug-thickness cement-av mixing phab ntsa siv txoj kev yog siv los tshem tawm cov dej-pov thawj ntaub, pawg-phab ntsa kev koom ua ke, TAD siv txoj kev prefabricated enclosure qauv, prestressed yeeb nkab. Pile enclosure qauv, sib sau ua ke steel ua ke A series ntawm ntsuab, txuag hluav taws xob thiab ib puag ncig tus phooj ywg tshiab technologies xws li kev txhawb nqa, ultra-siab dav hlau grouting, thiab DMP kev tsim kho txoj kev digital micro-kev cuam tshuam sib xyaw pawg.
Co-tsim thiab sib qhia cov kev tsim kho tshiab thiab cov thev naus laus zis tshiab
Nyob rau thawj txheej txheem ntawm lub rooj sib tham, thawj zaug, Song Qingjun, tus lwm thawj engineer ntawm Shanghai Underground Space thiab Engineering tsim lub koom haum ntawm Huajian Group, thiab Wang Boyang, project engineer ntawm Shanghai Machinery Construction Group Co., Ltd., raws li piav qhia lub prefabricated underground. diaphragm phab ntsa thev naus laus zis ntawm TAD txoj kev tsim kho, lub hauv paus ntsiab lus ntawm TAD txoj kev tsim kho thiab Daim ntawv tshaj tawm lub rooj sib tham yuav ua rau cov yam ntxwv ntawm cov khoom siv, kev xaiv cov cuab yeej siv, kev tsim kho, kev tsim kho thiab lwm yam.
Txoj kev siv TAD yog txoj kev tsim kho ntawm cov kwj dej-txiav sib dhos hauv av diaphragm phab ntsa. Txoj kev tsim kho no yog txhawm rau ntxig cov pob zeb ua vaj huam sib luag prefabricated phab ntsa nrog lub prestressed mortise thiab tenon mechanism {lock buckle} nyob rau hauv nruab nrab ntawm cov kwj dej-txiav cement-av diaphragm phab ntsa los tsim ib lub prefabricated underground diaphragm phab ntsa. Piv nrog rau cov txheej txheem kev tsim kho hauv av diaphragm phab ntsa, TAD txoj kev tsim kho muaj qhov zoo ntawm qhov chaw ua haujlwm tsawg, muaj zog yoog raws, siv sijhawm luv luv, thiab kev tiv thaiv ib puag ncig.
Shanghai Engineering Machinery Co., Ltd., Zhejiang Jitong Av thiab Cua Siv Tshuab Co., Ltd., Zhejiang University Binhai thiab Nroog Geotechnical Engineering Research Center, Zhejiang Architectural Design and Research Institute, Zhejiang University of Science thiab Technology, thiab Jianhua Tsev Khoom (Tuam Tshoj) tau ua tiav kev lag luam hauv kev lag luam-tsev kawm qib siab-kev tshawb fawb kev koom tes, Ua kom muaj kev sib raug zoo rau pej xeem ntawm kev suav theoretical ntawm TAD txoj kev tsim kho, kev npaj phab ntsa vaj huam sib luag, kev tsim tshuab, thiab lwm yam, thiab tsim ib txoj kev tsim kho tshiab rau kev tsim lub hauv paus pit. qhov thaiv.
Cov txheej txheem thib ob ntawm lub rooj sib tham: Dr. Li Qing ntawm Shanghai Underground Space thiab Engineering Design Research Institute ntawm Huajian Group tau ua ib daim ntawv tshaj tawm lub rooj sib tham ntawm cov micro-kev cuam tshuam kev sib xyaw tshuab ntawm DMP txoj kev tsim kho.
Cov micro-kev cuam tshuam kev sib xyaw pawg (DMP txoj kev tsim kho) txais yuav DMP-I digital micro-thab plaub sib xyaw pawg tshuab tshwj xeeb ntawm Shanggong Machinery, thiab siv cov kev tsim kho digital los tswj kev tsim kho tsis siv neeg. Lub slurry thiab roj ejected los ntawm lub grouting (cua) chaw nres nkoj txiav cov av ua ke, thiab tusyees sib tov cov cement thiab lwm yam curing agents nrog cov av los ua ib pawg nrog ib tug tej yam lub zog thiab impermeability. Los ntawm kev tswj tsis siv neeg ntawm lub siab sab hauv thiab ntau lub channel Lub slurry tso tawm thiab tso tawm ntawm cov yeeb nkab tshwj xeeb zoo li laum paub txog kev cuam tshuam me ntsis ntawm cov av nyob ib ncig ntawm pawg thaum lub sij hawm tag nrho cov txheej txheem ntawm pawg tsim, uas yog hu ua DMP. txoj kev.
DMP-I digital micro-disturbance mixing pile tshuab (DMP siv cov cuab yeej siv) yog cov cuab yeej siv tshiab digital siv tshuab sib xyaw pawg drilling tshuab ua ke tsim los ntawm SEMW thiab cov tuam txhab paub zoo hauv tsev, koom haum, thiab tsev kawm qib siab, feem ntau los daws cov pawg hauv lub cev thaum lub sijhawm kev tsim kho ntawm cov khoom sib xyaw ua ke. Me ntsis tsis sib xws, tsis tshua muaj cov ntaub ntawv, tsis yooj yim rau kev tswj kev tsim kho kom zoo, hloov av ntau dua, kev cuam tshuam loj ntawm kev tsim kho, tsis tshua muaj pawg tsim efficiency thiab lwm yam teeb meem. Cov cuab yeej siv thev naus laus zis siv thev naus laus zis, uas muaj cov yam ntxwv ntawm kev nyab xeeb thiab kev ntseeg siab, cov pawg siab zoo, muaj kev cuam tshuam me me hauv ib puag ncig, thiab kev tsim kho siab. Los ntawm GPS pawg chaw teeb tsa, pawg kab kab yog 850mm, thiab qhov siab tshaj plaws kev tsim kho qhov tob tuaj yeem ncav cuag 45m. Qhov kev tiv thaiv thaum sib tov tuaj yeem txhim kho qhov sib xyaw ua ke ntawm cov cement av thiab cov pawg zoo. Cov cuab yeej siv tsis tau tsuas yog ntxiv cov hniav txiav raws li xav tau, tiv thaiv cov av nplaum los ntawm kev lo rau hauv cov yeeb nkab laum thiab tsim cov av nkos, thiab txo qis kev cuam tshuam rau kev tsim, tab sis kuj muaj kev tsim tshwj xeeb ntawm cov cuab yeej drilling thiab cov cuab yeej txhawb nqa, thiab qhov ntsug ntawm pawg. tuaj yeem tswj tau ntawm 1/300. Cov efficiency yog pom tseeb.
SEMW tau cog lus rau kev txhim kho thiab kev tsim kho ntawm qhov chaw hauv av thiab kev tshawb fawb txog kev tsim kho technology, thiab tau cog lus los muab cov neeg siv khoom nrog tag nrho cov kev daws teeb meem rau cov hauv paus hauv av, pab kev tsim kho ntawm lub teb chaws hauv nroog infrastructure, ib txwm ua raws li lub tswv yim ntawm "cov kev pabcuam tshaj lij, tsim value" Cov neeg siv khoom tsim ua ke. Shanggong Machinery yuav, raws li ib txwm muaj, siv nws cov khoom sib sib zog nqus hauv thaj tsam ntawm pawg tshuab kom ua tau raws li cov kev xav tau ntawm cov neeg siv khoom, muab cov kev pabcuam tshaj lij rau cov neeg siv khoom, thiab tsim kom muaj nuj nqis.
