中文Prefabricated pawg tsim "nqa lub kov",
Tsis tshua muaj suab nrov, me me kev co, txuag hluav taws xob thiab emission txo,
Nroog pawg hauv paus "kev tiv thaiv ib puag ncig".
tsis ntev los no
Ntawm qhov chaw tsim kho ntawm thawj theem txhawb nqa qhov project ntawm Shanghai Huahong Hongli FAB2,
Ob txheej ntawm static drilling thiab rooting tshuab txhua tus tuav lawv txoj hauj lwm thiab ua ib txhij siv.
Tau ntsib nrog kev sib ntaus sib tua nyuaj rau lub sijhawm thiab sijhawm,
"Kub hauv paus" nqes mus nrog qhov sib sib zog nqus, ruaj khov thiab muaj tseeb dua kev sib ntaus sib tua,
Pw lub hauv paus ruaj khov rau txoj haujlwm Huahong Grace.
Lub hauv paus pawg ntawm qhov project no siv txoj kev zoo li qub drilling ntawm cov hauv paus hauv paus. Tag nrho ntawm 1,298 lub hauv paus pawg yog siv, uas yog kwv yees li 42,000 meters, thiab pawg ntev yog 29-36m. Xaiv pawg: PHC 500(100) AB C80 + PHDC 550-400(95) AB-500/400 C80, drilling txoj kab uas hla: 650mm, hauv qab expansion txoj kab uas hla: 975mm, hauv qab expansion qhov siab: 2000mm.
Lub tsev kawm ntawv nyob ib sab ntawm txoj kev thiab cov tsev uas twb muaj lawm thiab muaj cov kav dej. Ib puag ncig tej yam kev mob yog complex thiab rhiab heev rau deformation thiab vibration uas yuav tshwm sim thaum lub hauv paus tsim. Cov av compaction yuav tsum tau rau pawg hauv paus kev tsim kho yog siab heev. , Yuav ua li cas ua kom tiav qhov project nyob rau hauv 40 hnub nyob rau hauv cov kev ua hauj lwm nyuaj ntawm on-site kev tsim kho av nkos ua hauj lwm kuj tau los ua ib tug ntawm cov teeb meem nyob rau hauv lub pob zeb foundation tsim ntawm qhov project no.
Raws li ib tug ntsuab thiab ib puag ncig-phooj ywg pawg foundation tsim khoom kiag li nws tus kheej tsim los ntawmSEMW, SDP220H static drilling thiab rooting tshuab tau dhau los ua thawj qhov kev xaiv ntawm qhov project tog vim nws cov khoom zoo heev. Cov khoom no tsis tsuas yog muaj lub zog loj, qhov tob tob tob, kev ntseeg tau zoo thiab kev tsim kho siab, tab sis kuj muaj cov yam ntxwv ntawm kev vibration me me, tsis tshua muaj suab nrov, txuag hluav taws xob thiab emission txo thaum siv.
Ceev, qhov tob, thiab precision yog qhov zoo tshaj plaws txhais ntawm SDP220H zoo li qub drilling thiab rooting tshuab. Ob daim ntawm cov khoom siv ntawm qhov chaw tuaj yeem pawg txog 300m ntawm pawg hauv ib hnub nrog ib lub tshuab, thiab kev tsim kho kev ua haujlwm yog li 10-12 pawg, ua kom ruaj khov thiab ua haujlwm tau zoo.
Rau cov khoom lag luam zoo, kev lag luam yeej tsis yig los qhuas lawv. Cov lus teb los ntawm tus neeg teb xov tooj ntawm qhov chaw: "Raws li tus neeg ua haujlwm qub qub uas tau ua haujlwm lub tshuab tau ntau xyoo,SEMW's SDP220H zoo li qub drilling thiab rooting tshuab muaj lub zog loj, lub zog muaj zog, siab drilling thiab hauv qab nthuav dav kev tsim kho, thiab tag nrho lub tshuab ua haujlwm ruaj khov thiab ruaj khov. Nws yog qhov kev xaiv zoo rau qhov project. "Kev lav zoo rau kev tsim kho."
Raws li kev lag luam tus thawj coj muab kev daws teeb meem rau kev tsim kho hauv av, nyob rau hauv xyoo tas los no, SEMW tau txuas ntxiv ua kom muaj kev cuam tshuam los ntawm kev txhawb nqa kev siv thev naus laus zis tsis tu ncua, kev tshawb fawb thiab kev tsim khoom tshiab, thiab nthuav dav kev lag luam layout.
Nyob rau hauv lub neej yav tom ntej, SEMW yuav txuas ntxiv tsom mus rau cov neeg siv khoom qhov kev xav thiab kev lag luam kev lag luam, siv zog los tsim cov kev sib tw tseem ceeb sib txawv thiab cov khoom lag luam, tsim kom tau raws li cov neeg siv khoom xav tau tiag tiag thiab tus nqi-rau-nyiaj xav tau, thiab ua rau lub hauv paus tsim kev lag luam rau pem hauv ntej.
