High-strength Grout Saum 80MPa Rau Loj-scale Cua Fais Fab Foundation Projects-Industry Xov Xwm
Dec 04, 2023
Cua zog high-strength grouting khoom yog npaj nrog high-strength cov ntaub ntawv raws li aggregate, xis mas li binder, supplemented los ntawm high-fluidity, micro-expansion, anti-segregation thiab lwm yam khoom. Ntxiv ib qho dej rau hauv qhov chaw tsim kho, do kom zoo, thiab tom qab ntawd siv nws.
Ua ntej yuav piav qhia rau koj txog kev siv cov khoom siv muaj zog grouting rau lub hauv paus ntawm tus kiv cua, Xiaobian xav muab cov lus qhia ntxaws ntxaws rau koj txog cov yam ntxwv ntawm cov khoom siv muaj zog grouting ntawm no, yog li ntawd raws li nws qhov zoo, peb tuaj yeem piav qhia tau zoo dua thiab kawm cov yam ntxwv ntawm kev siv nws cov khoom raws li tus kiv cua:
(1) Lub zog thaum ntxov thiab lub zog siab: Lub zog tuaj yeem ncav cuag ntau dua 40-60MPa hauv ib hnub, thiab cov khoom tuaj yeem ua haujlwm tau ib hnub tom qab lub ncuav tiav lawm.
(2) Nws tus kheej ntws lub xeev: siab fluidity thiab siab tus kheej nruj, ncaj qha mus rau hauv lub hauv paus khoom, tsis muaj vibrating yuav cia li sau tag nrho cov khoob rau lub hauv paus khoom.
(3) Micro-expansion: Lub micro-expansion kev ua tau zoo ntawm cov khoom tuaj yeem ua kom ntseeg tau tias kev sib raug zoo ntawm cov cuab yeej siv thiab lub hauv paus txhim khu kev qha.
(4) Anti-roj seepage: nws lub zog tsis txo qis tom qab soaking hauv roj rau 30 hnub
(5) Zoo durability: 2 lab qhov kev sim qaug zog, 50 qhov kev sim khov-thaw lub voj voog tsis muaj kev hloov pauv hauv kev siv.
(6) Kev tsim kho yooj yim: Qhov chaw tsim kho tsuas yog siv tau los ntawm kev ntxiv dej thiab nplawm, thiab daim ntawv thov hauv lub hauv paus cua turbine:
(1) Daim ntawv thov nyob rau hauv lub offshore cua turbine foundation
Txhawm rau kom txo qis kev ntxhov siab thiab qaug zog los ntawm kev vuam, thiab ua lub luag haujlwm hauv kev sib tw, kev sib txuas ntawm cov ntug dej hiav txwv cua turbine foundation thiab pawg hauv paus feem ntau txuas nrog lub zog siab grouting. Raws li kev xav tau tshwj xeeb thiab kev tsim kho tshwj xeeb ntawm ntug dej hiav txwv cua turbine foundation grouting, cov khoom siv muaj zog grouting muaj cov yam ntxwv ntawm cov dej ntws loj, tiv thaiv kev sib cais thiab kev ruaj ntseg, siab thaum ntxov wetting, siab kawg lub zog, siab elastic modulus, siab. ntim stability, siab qaug zog tsis kam, tsis tshua muaj cua sov ntawm hydration thiab lwm yam ntxwv Tom qab lub grouting tiav, lub grouting kev twb kev txuas seem tuaj yeem tiv taus qhov tsis zoo ua ke ntawm cua turbine load, yoj quab yuam, tidal quab yuam thiab lub nkoj cuam tshuam quab yuam. Los ntawm kev ntxhov siab, qhov sib txuas ntawm qhov sib txuas ntawm lub hauv paus cua turbine yog qhov tseem ceeb ntawm kev xa cov cua turbine load mus rau lub hauv paus hauv paus, thiab los ntawm kev tsim kho, grouting ntawm offshore cua turbine foundation yog cov txheej txheem tseem ceeb ntawm cov yeeb nkab steel. pawg sinking thiab lub hauv paus installation, yog li ntawd, kev tsim thiab kev tsim kho ntawm lub grouting kev twb kev txuas seem yog ib qho tseem ceeb heev los xyuas kom meej qhov zoo ntawm cov cua turbine, thiab nws cov kev ntseeg tau yog ib qho tsim nyog los xyuas kom meej cov kev ua hauj lwm ntawm offshore cua zog.
(2) Daim ntawv thov hauv onshore cua turbine foundation
1. Lub hauv paus nplhaib lub hauv paus: vim yog qhov tseem ceeb ntawm kev ntxhov siab ntawm cov hlau thiab pob zeb, kev sib txuas ntawm cov hlau thiab pob zeb yog ib qho yooj yim ua tsis tau raws li qhov kev txiav txim ntawm cyclic load, thiab cov kab nrib pleb ntawm lub hauv paus nplhaib thiab cov cua turbine foundation yog loj heev. , lub slurry (ua pa) nyob rau hauv cov ntaub ntawv ntawm dej, thiab lub inclination ntawm lub hauv paus nplhaib tshaj tus qauv, uas cuam tshuam rau ib txwm ua hauj lwm ntawm lub cua turbine. Nyob rau lub sijhawm no, kev kho lub zog ntawm kiv cua lub hauv paus yuav raug ua, thiab cov txheej txheem ntawm grouting feem ntau siv, thiab cov khoom siv muaj zog grouting tuaj yeem siv tau.
2. Anchor bolt foundation: Nyob rau hauv cov txheej txheem kev tsim kho, yuav tsum muaj cov khoom siv grouting theem nrab thiab cov khoom siv muaj zog, nrog rau qib tsis tsawg tshaj C80, uas yuav tsum tsis txhob shrinkage, nws tus kheej-leveling, micro-expansion, thiab siab. - lub zog grouting nyob rau hauv lub kiv cua thauj tog rau nkoj bolt foundation
