1 Txoj kev grouting
Feem ntau, txoj kev grouting yog saws los kho cov kab nrib pleb ntawm kev tsim cov qauv. Txoj kev no tsuas yog siv cov cuab yeej siv siab los nchuav qee cov khoom siv cementing rau hauv pob zeb tawg. Tom qab hardening, cementing cov ntaub ntawv tuaj yeem txuas nrog cov pob zeb ua kom muaj zog thiab sib khi. Polyurethane, cement, epoxy, lwm
Feem ntau zoo cementing cov ntaub ntawv, daim ntawv thov yog dav heev, feem ntau yog los ntawm txoj kev ntawm caulking los kaw cov pob zeb tawg, nyob rau hauv dav dav, nrog cov kab nrib pleb gouge, nyob rau hauv qhov zawj rau tso cov ntaub ntawv tsis muaj dej, los ntawm txoj kev no los kaw cov kab nrib pleb.
2. Txoj kev kho deg
Kev kho deg yog ib txoj kev kho ntau. Nws muaj qhov zoo ntawm kev ua haujlwm yooj yim, nyob rau hauv cov qauv ntawm ib co tsis cuam tshuam cov qauv bearing muaj peev xwm nyob rau hauv tus txheej txheem ntawm kev kho deg tawg, daim ntawv thov yog dav heev, feem ntau nyob rau hauv cov xwm txheej ntawm cov qauv ntawm qhov chaw ntawm cov cement slurry, cement dab, los yog yuav siv rau hauv cov pob zeb tiv thaiv pob zeb xws li asphalt, pleev xim, thiab zam kev tawg ntxiv, lwm., feem ntau nyob rau hauv cov xwm txheej ntawm cov iav fiber ntau tuaj yeem teem caij rau ntawm qhov tawg ntawm qhov muab tshuaj txhuam, tswj qhov tawg.
(1) Cement mortar yuav tsum tau siv rau ntawm qhov chaw
Txhawm rau ntxiv kom ntseeg tau tias qhov chaw, Kev txhim kho ntawm kev ua tau zoo ntawm cov dej tsis zoo hauv cov cement mortar rau hauv ib qho nyiaj ntawm ferric chloride waterproofing tus neeg sawv cev, muaj cov nyhuv zoo heev, yog li tom qab ua tiav cov mortar rau saum npoo ntawm yas zaj duab xis npog, yog li tuaj yeem ua ke nrog pob zeb thiab mortar, thiab tuaj yeem siv los txhawb tus qauv, extrusion ntsia hlau nruj, rau
Qee lub pob zeb muaj qhov yuav tsum tau ua dej tsis zoo, tuaj yeem siv cov cement slurry thiab 1∶2 cement mortar rau alternating daub, nyob rau hauv dav dav, yuav tsum daub 3-5 zaug, los tsim cov nyhuv dej tsis zoo ntawm cov txheej txheem nruj, tom qab daub 3-5 zaug, npog, thiab tom qab ntawd los ntawm txoj kev sprinkling dej rau kho.
Cov pob zeb tawg ib ncig ntawm qhov sib thooj ntawm qhov chaw gouging, thiab dej ntub, thiab ntxuav lossis chiseling raws cov kab nrib pleb rau hauv qhov tob ntawm 15 ~ 20mm, dav ntawm 150 ~ 200mm zawj, thiab txhuam ib txheej ntawm cov cement mortar, Tom qab ntawd los ntawm 1∶2 cement mortar daub, tus naj npawb ntawm kev tswj hauv 2-3 sij hawm, lub thickness ntawm mas nyob rau hauv 10 ~ 20mm.
(2) Siv epoxy cement rau ntawm qhov chaw
Nyob rau hauv tus txheej txheem ntawm kev tawg ntawm pob zeb ua haujlwm, xav tau los ntawm cov scraper thiab txhuam dipped nyob rau hauv ib qho me me ntawm cov cement, sib npaug ntawm qhov chaw ntawm pob txha tawg, rau qee qhov ntawm qhov dav ntawm qhov slit yog qhov me me thiab tsawg dua qhov tsis tshua muaj zog tawg, tuaj yeem kho raws li qhov no, thaum ua tiav kev kho, tuaj yeem siv cov ntawv xuab zeb, steel hlau
Txhuam los ntxuav thiab qhuav cov roj, siv acetone los yog xylene, thiab preheat nws nrog ib tug blowtorch yog hais tias lub nto yog moist.
(3) Glue iav-silk ntaub los ntawm epoxy slurry
Ua ntej, epoxy resin nplaum yog kho thiab coated nrog 1 ~ 2 txheej ntawm iav fiber ntau daim ntaub. Ua ntej siv iav fiber ntau daim ntaub, Cov iav fiber ntau yuav tsum tau muab rhaub hauv dej alkaline rau 0.5 ~ 1h, uas tuaj yeem tshem tawm cov roj thiab siv quav ciab thiab txhim kho kev sib raug zoo. Thib ob, nyob rau hauv cov txheej txheem primer thib ob, tom qab 24 teev ntawm natural curing, lub substrate tuaj yeem ua tib zoo coated, ua raws li kev tso cov iav fiber ntau daim ntaub. Yog xav tau ob txheej, ib txheej yuav tsum tau affixed ua ntej thiab compacted, thiab tom qab ntawd cov txheej thib ob yuav tsum tau muab sib xyaw ua ke thiab daim ntaub dav ntawm txheej thib ob yuav tsum yog 10 ~ 12mm dav dua li ntawm thawj txheej., los pab txhawb txoj kev tuav ntug.
3. Kev tsim vaj tsev loj
Ua ntej tshaj plaws, nyob rau hauv kev tsim qauv, cov neeg tsim qauv yuav tsum teeb tsa cov qauv loj-ntim pob zeb tsim nyog, thiab txo qhov ntim engineering thiab tag nrho hydration cua sov theem ntawm qhov chaw ntawm kev ua kom ntseeg tau qhov kev tsim kho thiab kev ua haujlwm zoo. Piv txwv li, rau ib feem ntawm cov qauv kev ntxhov siab tsis tseem ceeb ib feem tuaj yeem hollowed tawm ib feem ntawm cov pob zeb pob zeb, optimize thiab txhim kho lub hauv paus qauv siv av
Lub tswv yim square nyhav muab qhov tsim nyog infrastructure stability txhawb rau kev tsim kho tej yaam num, yog li txo qhov ntim ntawm cov pob zeb ua vaj tse. Ntxiv rau, Cov kev tshawb fawb tau pom tias qhov kub thiab txias yog nyob ntawm cov qauv ciam txheej cuam tshuam rau lub tsev qauv siv load, yog li ntawd, nyob rau hauv lub loj pob zeb engineering qauv tsim, designers yuav tsum tau them sai sai mus rau lub ciam teb txwv tej yam kev mob ntawm optimization, qhov kub ntxhov cuam tshuam pom tseeb geological tej yam kev mob, yuav tsum tau raws li kev tsim vaj tse teeb tsa zawv zawg txheej, yog li tsis muaj zog ntawm qhov kub thiab txias load stress restraint, zam dhau load tsim qhov teeb meem tawg.
