Micro-surfacing ndi njira yodzitetezera yomwe imagwiritsa ntchito mtundu wina wa tchipisi ta miyala kapena mchenga, zodzaza (simenti, laimu, phulusa la ntchentche, ufa wamwala, etc.) ndi phula lopangidwa ndi polima lopangidwa ndi emulsified, zosakaniza zakunja ndi madzi mugawo linalake. Sakanizani mu chisakanizo chothamanga ndikuchifalitsa mofanana pazitsulo zosindikizira pamsewu.
Kusanthula kamangidwe kanjira ndi zomwe zimayambitsa matenda apamsewu
(1) Kulamulira khalidwe laiwisi
Panthawi yomanga, kuwongolera kwa zinthu zopangira (coarse aggregate diabase, fine aggregate diabase powder, modified emulsified asphalt) kumayamba ndi zinthu zolowera zomwe zimaperekedwa ndi omwe amapereka, kotero kuti zinthu zomwe zimaperekedwa ndi wogulitsa ziyenera kukhala lipoti loyeserera. Kuphatikiza apo, zidazo zimawunikiridwa mozama motsatira miyezo yoyenera. Pa nthawi yomanga, ubwino wa zipangizo ziyenera kufufuzidwanso. Ngati pali kukayikira kulikonse, khalidweli liyenera kufufuzidwa mwachisawawa. Kuonjezera apo, ngati kusintha kwa zipangizo zapezeka, zinthu zomwe zatumizidwa kunja ziyenera kuyesedwanso.
(2) Kuwongolera kusasinthasintha kwa slurry
Pogawaniza, mapangidwe amadzi a slurry osakaniza atsimikiziridwa. Komabe, molingana ndi chikoka cha chinyezi chomwe chili pamalopo, chinyezi chambiri, kutentha kwa chilengedwe, chinyezi chamsewu, ndi zina zambiri, malowa nthawi zambiri amafunika kusintha slurry molingana ndi momwe zinthu zilili. Kuchuluka kwa madzi omwe amagwiritsidwa ntchito posakaniza slurry amasinthidwa pang'ono kuti asagwirizane ndi kusakaniza koyenera kufunikira pokonza.
(3) Kuwongolera nthawi ya Micro-surface demulsification
Panthawi yomanga misewu yaying'ono, chifukwa chofunikira kwambiri chamavuto amsewu ndikuti nthawi ya demulsification yosakanikirana ndi slurry ndiyoyambika kwambiri.
Kuchulukana kosagwirizana, kukwapula, ndi kusagwirizana kwa phula komwe kumayambitsidwa ndi demulsification zonse zimayamba chifukwa cha kuchepa msanga. Pankhani ya mgwirizano pakati pa wosanjikiza kusindikiza ndi pamwamba msewu, demulsification msanga adzakhalanso zowononga kwambiri kwa izo.
Zikapezeka kuti kusakaniza kumachotsedwa nthawi isanakwane, kuchuluka koyenera kwa retarder kuyenera kuwonjezeredwa kuti musinthe mlingo wa filler. Ndipo yatsani chosinthira chamadzi chisanakhale chonyowa kuti muwongolere nthawi yosweka.
(4) Kulamulira tsankho
Panthawi yokonza misewu ikuluikulu, tsankho limachitika chifukwa chazifukwa monga makulidwe owonda, makulidwe osakanikirana, ndi malo olembera (osalala komanso makulidwe ena).
Panthawi yokonza, ndikofunikira kuyang'anira makulidwe a paving, kuyeza makulidwe apang'onopang'ono munthawi yake, ndikusintha munthawi yake ngati pali zofooka zilizonse. Ngati gradation wa osakaniza kwambiri coarse, ndi gradation wa slurry osakaniza ayenera kusinthidwa mkati gradation osiyanasiyana kusintha tsankho chodabwitsa pa yaying'ono padziko. Pa nthawi yomweyi, zolembera zamsewu zomwe zimayenera kukonzedwa ziyenera kupedwa musanakhomedwe.
(5) Kuwongolera makulidwe amisewu
Pokonza misewu yayikulu, makulidwe apakati osakaniza ocheperako amakhala pafupifupi nthawi 0,95 mpaka 1.25. M'magawo owerengera, mpendero uyeneranso kukhala pafupi ndi mbali yokhuthala.
Pamene chiwerengero cha magulu akuluakulu pamagulu ndi aakulu, chiyenera kuikidwa mowonjezereka, apo ayi magulu akuluakulu sangathe kukanikizidwa muzitsulo zosindikizira. Komanso, ndizosavuta kuyambitsa zokopa pa scraper.
M'malo mwake, ngati kuphatikizikako kuli bwino panthawi yogawaniza, ndiye kuti msewu wapamsewu uyenera kukhala wocheperako panthawi yokonza msewu waukulu.
Panthawi yomanga, makulidwe a paving ayenera kuyendetsedwa ndikuyesedwa kuti atsimikizire kuchuluka kwa slurry osakaniza omwe amagwiritsidwa ntchito popanga misewu yayikulu. Kuonjezera apo, poyang'anira, vernier caliper ingagwiritsidwe ntchito kuyeza mwachindunji chisindikizo cha slurry pamtunda wawung'ono wa msewu waukulu watsopano. Ngati ipitilira makulidwe ena, bokosi lopatulira liyenera kusinthidwa.
(6) Kuwongolera maonekedwe a msewu waukulu
Pakupanga ma micro-surface pamisewu yayikulu, mphamvu zamapangidwe amsewu ziyenera kuyesedwa pasadakhale. Ngati kutayikira, mafunde, kufooka, maenje, matope, ndi ming'alu zikuwoneka, misewu iyi iyenera kukonzedwa musanatseke kumanga.
Panthawi yokonza, onetsetsani kuti mukuwongoka ndikuwonetsetsa kuti mipiringidzo kapena misewu ikufanana. Kuonjezera apo, pokonza, m'lifupi mwake kuyenera kutsimikiziridwa, ndipo zolumikizira ziyenera kuyikidwa momwe zingathere pamtunda wogawanitsa njira kuti zithetse kukhazikika kwa kusakaniza ndi kuteteza zipangizo kuti zisalekale msanga mu bokosi lopaka kuti zitsimikizire kuti iwo ndi Kuchuluka kwa madzi panthawi ya ndondomekoyi ndi yofanana komanso yochepa.
Kuphatikiza apo, zida zonse ziyenera kuyang'aniridwa pakutsitsa kuti zichotse tinthu tating'onoting'ono, ndipo zolakwika ziyenera kusinthidwa munthawi yodzaza kuti mawonekedwe awo azikhala osalala komanso osasinthasintha.
(7) Kuwongolera kutseguka kwa magalimoto
Kuyesa chizindikiro cha nsapato ndi njira yomwe imagwiritsidwa ntchito nthawi zambiri yowunikira njira yotsegulira misewu yayikulu pakukonza misewu yayikulu. Ndiko kunena kuti, ikani kulemera kwa munthuyo pa muzu kapena pansi pa nsapato ndi kuyimirira pa chosindikizira kwa masekondi awiri. Ngati chophatikizacho sichinatulutsidwe kapena kukakamira ku nsapato ya munthuyo pochoka pamalo osindikizira, amatha kuonedwa ngati malo ochepa. Ntchito yokonza ikatha, imatha kutsegulidwa kwa magalimoto.
