ORCA me me asphalt pavers, nrog rau ultra- nqaim paving dav dav ntawm 0.3-1.45m, yog irreplaceable rau precision tej yaam num xws li kev taug kev gaps, kev kho ntug ntug, pipeline trench backfills, thiab scenic cheeb tsam txoj kev. Tsis zoo li cov pavers me me, lawv cov qauv nqaim dav dav coj cov teeb meem tshwj xeeb: ntug tsis ruaj khov, muaj kev pheej hmoo siab ntawm cov khoom sib cais, thiab nyuaj rau kev tswj cov tuab tuab. Txhawm rau kom ua tiav qhov ua tau zoo ntawm ORCA pavers, pab pawg tsim kho yuav tsum tau txais cov phiaj xwm tswj xyuas kom zoo raws li lawv cov kev tsim tshwj xeeb.
1. Ua ntej-Kev Npaj Kev Tsim Kho: Ultra-Kev Hloov Kho Yooj Yim
(1) Cov cuab yeej Calibration rau nqaim -Kev ua haujlwm dav
Ua kom pom tseeb ntawm screed precision: Calibrate ORCA's screed flatness kom tsawg dua los yog sib npaug li 0.3mm / m ( nruj dua li cov qauv pavers) siv cov qib laser, kom tsis txhob muaj kev sib tsoo uas tuaj yeem ua rau paving tsis sib xws hauv 0.3m ultra- hom nqaim.
Kho cov khoom siv thauj khoom: ORCA's auger system xav tau zoo -tu- txo auger ceev los ntawm 20% piv rau cov pavers dav dua kom tsis txhob muaj cov khoom siv ntau dhau ntawm cov npoo nqaim, tiv thaiv kev sib cais.
Kuaj khiav ntawm mock-ups: Ua 5-10m sim paving nrog lub hom phiaj dav (piv txwv li, 0.5m rau txoj kev khoob) txhawm rau txheeb xyuas qhov tuab tuab (± 3mm sib txawv tau tso cai) thiab ntug kev ncaj ncees.
(2) Kev Txhim Kho Cov Txheej Txheem rau Cov Pavements nqaim
Micro-leveling: Siv ib qho ncaj los xyuas lub hauv paus; ib qho kev tsis sib xws loj dua lossis sib npaug li 5 hli yuav tsum tau ntim nrog asphalt emulsion mortar, vim ORCA qhov chaw sib cuag nqaim ua kom lub hauv paus tsis xws luag.
Edge reinforcement: Nruab ib ntus steel sab cov ntaub ntawv (qhov siab txuam paving thickness) rau qhov dav<0.8m, or apply a layer of asphalt primer to the edge substrate to enhance adhesion and prevent collapse.
2. Kev Tswj Tus Txheej Txheem Kev Tsim Kho: Nqaim -Kev Tshwj Xeeb Dav
(1) Kev tswj kev sib tov rau me me -Batch Paving
Kub precision: ORCA lub hopper me me ua rau kom poob kub sai. Khaws kub - sib tov asphalt (HMA) kub ntawm 140-165℃thaum thauj khoom, thiab siv cov ntaub thaiv npog rau kev thauj mus los. Tshem tawm cov khoom sib tov txias hauv qab 115 degree.
Batch pub: Muab cov khoom siv me me, nquag ua haujlwm kom lub hopper 1/3-1/2 puv-tsis txhob overloading (uas ua rau kev sib cais) los yog underloading (uas nthuav tawm lub auger, ua rau noj tsis sib xws).
(2) Paving ua haujlwm: khov kho & meej
Kev tswj ceev: Ua kom qeeb, qhov nrawm ntawm 1-2.5m / min (slower dua pavers dav). Sudden ceev hloov nyob rau hauv ultra-nqaim hom ua rau thickness fluctuations; siv ORCA's cruise control function rau stability.
Ntug tiv thaiv: Rau qhov dav<0.6m, attach the paver's dedicated edge guide wheel to the side form, ensuring the screed stays aligned. Preheat the screed extension plates to 110℃+ to prevent asphalt adhesion and edge raveling.
Kev hloov kev vibration: Siv qis- mus rau- nruab nrab vibration zaus (2500-3500 vibrations/min) rau ORCA-ntau zaus hauv qhov nqaim paving tuaj yeem tsoo cov sib xyaw. Rau coarse-qib mixs, me ntsis nce amplitude los xyuas kom meej compaction.
(3) Compaction: Micro-Rolling rau Narrow Spaces
Cov khoom sib txuam: Siv 0.5-1.5 tuj micro- vibratory rollers lossis tes- tuav vibratory phaj (ORCA-tshaj) kom nkag mus rau thaj chaw nruj. Zam cov menyuam loj uas ua rau cov npoo puas.
Rolling sequence: Yob tam sim ntawd tom qab paving (hauv 2-3 feeb) nrog "static → vibratory → static" cov kauj ruam. Sib tshooj txhua qhov dhau los ntawm 1/2 qhov dav dav ntawm cov menyuam (ntau tshaj li tus qauv) kom tsis txhob muaj qhov sib txawv.
Qhov kub thiab txias: Pib dov Ntau dua lossis sib npaug li 125 degree, qhov kawg dov Loj dua lossis sib npaug li 75 degree. Rau ultra- strips nqaim (0.3-0.5m), ua tiav dov li ntawm 5 feeb kom tiv thaiv kom txias-vim tawg.
3. Tom qab-Kev Tshawb Fawb Kev Tsim Kho: Lub Hom Phiaj Tshawb Fawb
Thickness & flatness: Laum 3-5 core qauv ib 50㎡ (siab dua li tus qauv) los xyuas cov thickness (compaction ntom ntau dua los yog sib npaug rau 96% rau AC-10 sib tov). Siv 2m straightedge rau flatness (tso cai deviation Tsawg tshaj los yog sib npaug rau 2mm / 2m).
Kev kho kev sib koom ua ke: Rau kev sib law liag, sib tshooj tshiab asphalt nrog cov pavement qub los ntawm 3-5cm (nqaim dua li tus qauv) thiab txiav ntau dhau tom qab kev cog lus. Rau transverse pob qij txha, txiav vertically nrog lub pob zeb pom thiab preheat qhov sib koom ua ke rau 90℃ua ntej paving.
Kev txwv kev thauj mus los: Khaws thaj chaw kaw rau 6-8 teev (ntev dua li tus qauv) kom txog thaum qhov kub thiab txias poob qis dua los yog sib npaug li 45 degree, vim qhov nqaim pavements muaj ntau dua rau cov log tsheb puas.

Xyuas kom paving zoo nrogORCAme pavers (0.3-1.45m) hinges ntawm "nqaim- dav adaptation"-los ntawm cov cuab yeej precision calibration thiab micro- theem pib npaj kom qeeb - kev ua haujlwm tsis tu ncua thiab micro- dov. Los ntawm kev hais txog cov kev sib tw tshwj xeeb ntawm kev nqaim nqaim (ntug tsis ruaj khov, kev sib cais, kev poob qis), cov lus qhia no txhawb nqa ORCA qhov muaj zog, xa cov pav ca, tuab, thiab ruaj khov rau cov haujlwm tshwj xeeb. Rau pab pawg tsim kho, kev paub txog cov txheej txheem no yog qhov tseem ceeb rau kev siv ORCA qhov kev ua tau zoo thaum tswj xyuas cov qauv kev lag luam zoo.
