Kev tsim kho ib puag ncig
(1) Kev tsim kho yog ua nyob rau hauv ib puag ncig uas huab cua kub tsis qis dua 5 ℃ thiab txoj kev kub tsis qis dua 10 ℃;
(2) Txoj kev tsim kho qhov chaw yuav tsum huv, qhuav, thiab tiaj tus. Tom qab los nag, txoj kev nto yuav tsum qhuav li 24 teev ua ntej kev tsim kho;
(3) Lub asphalt pavement tuaj yeem tsim ua 10 teev tom qab nws tso thiab asphalt tau txias. Txoj kev tsheb ciav hlau tshiab tuaj yeem tsim ua 20 hnub tom qab nws tau tso thiab qhib rau kev khiav tsheb.
Txoj kev siv thiab cov kauj ruam
(1) Pavement tu: Txoj kev saum npoo yuav tsum tau ntxuav ua ntej kev tsim kho. Muaj cov khoom ntab thiab cov khoom me me uas yooj yim rau poob ntawm txoj kev.
Siv txhuam txhuam los ntxuav nws ua ntej kev tsim kho;
(2) Siv cov primer: Qhib cov nplaum nplaum thiab do kom sib npaug; siv cov tshuaj hnyav-resistant velvet rau cov menyuam los yog txhuam kom siv cov nplaum rau hauv av sib npaug thiab nyob rau hauv ib nrab tuab. Thaum ua ntawv thov, cov nplaum yuav tsum yog 2-3 cm tshaj qhov dav ntawm kab kos lossis kos npe. Thaum thov cov kua nplaum rau hauv av, yuav tsum siv qee qhov quab yuam kom ntseeg tau tias cov kua nplaum txheej thiab hauv av tuaj yeem nkag mus rau hauv tag nrho, tshwj xeeb tshaj yog cov kua nplaum ntawm cov ces kaum ntawm daim ntawv lo yuav tsum tau siv rau hauv qhov chaw; Nyob ntawm seb lub thickness thiab uniformity ntawm cov kua nplaum, tom qab ib txwm daim ntawv thov Cia kom qhuav rau 5-10 feeb ua ntej pasting.
(3) Tom qab ua tiav tiav, kev kho siab yuav tsum tau ua los ntawm dov nrog cov khoom hnyav, ntaus nrog roj hmab rauj, thiab phau ntawv nias. Tshwj xeeb, cov ces kaum ntawm daim ntawv lo yuav tsum tau ua tib zoo ntaus kom paub meej tias qhov chaw muaj kev sib raug zoo. Yog tias muaj kev tso cai, cov txiaj ntsig yuav zoo dua yog tias cov tsheb tsav maj mam dhau los ntawm daim kab xev nplaum tag nrho. Thaum lub ambient kub yog tsawg, daim kab xev los yog kos npe yuav tsum tau ci nrog ib tug blowtorch los yog liquefied roj hluav taws thiab ces pressurized kom tau zoo dua.
(4) Tom qab kev sib raug zoo raws li cov txheej txheem saum toj no, nws tuaj yeem qhib rau kev khiav tsheb ib txwm. Txawm li cas los xij, cov nplaum tsis tau mus txog qhov zoo tshaj plaws kev sib txuas lub zog nyob rau lub sijhawm no. Feem ntau, sim kom tsis txhob yuam kev tsim kua muag thiab tev tawm hauv 48 teev.
(5) Yog tias daim ntawv lo lossis kos npe muaj lub pob hauv zos, nws txhais tau hais tias cov roj hmab txheej tsis tau qhib rau lub sijhawm txaus lossis huab cua tsis tau tag. Koj tuaj yeem siv cov cuab yeej ntse kom thawb cov kev hu, tso roj, thiab rov ua dua nws.
Tej yam yuav tsum nco ntsoov
(1) Thaum thauj, khaws cia thiab siv cov khoom no, thov kom nws deb ntawm qhov hluav taws kub lossis qhov chaw muaj cua sov thiab sim ua kom muaj cua zoo.
(2) Tom qab cov nplaum siv rau hauv cov khoom no tau thov, lub hau yuav tsum tau muab ntim rau hauv lub sijhawm kom tiv thaiv cov kuab tshuaj los ntawm evaporating thiab ua kom khov heev, ua rau nws tsis yooj yim rau kev thov.
(3) Txoj kev preformed reflective tapes thiab cov cim qhia tau zoo rau lub sijhawm ntev yam tsis muaj cov khoom siv los ua nkig. Cov nplaum siv hauv cov khoom no muaj lub neej txee ntawm ib xyoos. Yog tias nws tshaj lub txee lub neej, nws yuav tsum tau sim ua ntej siv.
