Tom qab ntxuav, qee zaum nws yuav tsum tau nthuav dav thiab sib sib zog nqus cov kab nrib pleb kom zoo dua embed cov khoom kho, uas yog hu ua slotting.

2. Kub grouting txoj kev

Kub grouting yog cov txheej txheem kev kho mob tawg, tshwj xeeb tshaj yog tsim rau cov kab nrib pleb me me (feem ntau tsis tshaj 1 centimeter). Txoj kev no siv lub tshuab tshwj xeeb kub yaj sealing tshuab los txhaj cov khoom sealing (feem ntau hloov asphalt lossis tshwj xeeb sealing nplaum) rhuab mus rau lub xeev ntws mus rau hauv qhov tawg. Tom qab txias thiab solidification ntawm cov khoom siv grouting, nws tuaj yeem tiv thaiv dej infiltration, txo qhov kev nthuav dav ntxiv ntawm cov kab nrib pleb, thiab rov ua kom du ntawm txoj kev.

3. Txoj kev kho sealant

Rau cov kab nrib pleb nrog qhov dav dav lossis qhov tob tob, txoj kev kho sealant tuaj yeem siv tau. Txoj kev no siv cov khoom siv sib khi ua kom txias, uas tuaj yeem siv rau ntawm chav tsev kub tsis tas yuav tsum tau cua sov. Sealant muaj qhov zoo adhesion thiab elasticity, uas tuaj yeem hloov mus rau thermal expansion thiab contraction hloov ntawm txoj kev nto, thiab tiv thaiv cov kab nrib pleb los ntawm kev tawg dua. Thaum lub sij hawm tsim kho, tusyees thov los yog sau lub sealant rau hauv cov kab nrib pleb, thiab thaum lub nto yog theem, tsheb yuav qhib.

4. Self-adhesive seam daim kab xev txoj kev

Self-adhesive daim kab xev yog ib qho yooj yim thiab siv tau txoj kev kho mob tawg, tshwj xeeb tshaj yog haum rau kev kho sai. Hom kab xev nplaum no muaj ib txheej ntawm tus kheej nplaum rau sab nraub qaum. Thaum lub sij hawm tsim kho, tsuas yog tev tawm cov yeeb yaj kiab tiv thaiv thiab ncaj qha mus rau qhov chaw ntxuav ntawm qhov tawg. Nws tuaj yeem nruj nreem nias los ntawm dov. Cov ntaub nplaum nplaum feem ntau muaj cov khoom hnyav molecular polymers, uas muaj cov huab cua zoo tiv thaiv thiab tsis muaj dej tsis zoo, tuaj yeem kaw cov kab nrib pleb thiab txuas ntxiv kev pab cuam lub neej ntawm txoj kev.

5. Micro nto kho thiab ultra-nyias hnav txheej tshuab

Txhawm rau npog thaj chaw loj ntawm cov kab nrib pleb zoo lossis kev tiv thaiv kev saib xyuas, kev kho mob micro deg lossis ultra-nyias txheej txheej tshuab siv tau. Ob txoj kev koom nrog kev tso ib txheej nyias ntawm asphalt sib tov rau ntawm txoj kev uas twb muaj lawm, nrog lub thickness ntawm kwv yees li 1 centimeter. Lawv tuaj yeem tsis tsuas yog kaw cov kab nrib pleb uas twb muaj lawm, tab sis kuj tseem txhim kho tag nrho lub zog thiab ua haujlwm ntawm txoj kev nto, ncua kev tsim cov kab nrib pleb tshiab. Thaum lub sij hawm tsim kho, ntxuav thiab pretreat txoj kev nto ua ntej, ces tusyees kis los yog tshuaj tsuag cov sib tov, thiab thaum kawg siv ib tug me me rau compact.

6. Grouting kho txoj kev

Rau kev sib sib zog nqus cov kab nrib pleb, grouting kho txoj kev yuav tsum tau. Txoj kev no suav nrog kev khawb tob rau hauv cov kab nrib pleb thiab tom qab ntawd txhaj cov cement-based lossis lwm yam tshuaj grout los sau cov kab nrib pleb thiab txhim kho cov qauv ntawm txoj kev. Grouting tuaj yeem tsis tsuas yog muab cov kab nrib pleb zoo xwb, tab sis kuj txhim kho kev ruaj ntseg ntawm lub hauv paus, ua rau nws tsim nyog rau kev kho cov kab nrib pleb los ntawm lub hauv paus kev sib hais haum thiab lwm yam laj thawj.
