Micro-surfacing tekinoroji yekuchengetedza tekinoroji inoshandisa imwe giredhi yematombo machipisi kana jecha, mafirita (simende, lime, dota renhunzi, hupfu hwebwe, nezvimwewo) uye polymer-yakagadziridzwa emulsified asphalt, ekunze anosanganisa uye mvura mune imwe chikamu. Isanganise mumusanganiswa unoyerera uye wozoiparadzira zvakaenzana pamusoro pechisimbiso chekuvhara pamugwagwa.
Kuongororwa kwekugadzirwa kwepavement uye zvikonzero zvezvirwere zvepavement
(1) Kudzora kwemhando yezvigadzirwa
Munguva yekuvaka, kutonga kwezvinhu zvakasvibirira (coarse aggregate diabase, yakanaka aggregate diabase poda, yakagadziridzwa emulsified asphalt) inotanga nezvinhu zvekupinda zvinopihwa nemutengesi, saka zvinhu zvinopihwa nemutengesi zvinofanirwa Kuve neyakarongwa bvunzo repoti. Uyezve, zvinhu zvacho zvinoongororwa zvizere zvinoenderana nemazinga akakodzera. Panguva yekuvaka, kunaka kwezvinhu zvakasvibirira kunofanirawo kuongororwa. Kana paine kusahadzika kupi, kunaka kunofanirwa kutariswa zvisina tsarukano. Pamusoro pezvo, kana shanduko mumidziyo yakawanikwa, zvinhu zvinotengeswa kunze kwenyika zvinofanirwa kuongororwa zvakare.
(2) Kudzora kwe slurry kuenderana
Muchigadziro chekuenzanisa, kugadzirwa kwemvura yemusanganiswa we slurry yakatemwa. Nekudaro, zvinoenderana nepesvedzero yehunyoro panzvimbo, hunyoro hwemuunganidzwa, tembiricha yezvakatipoteredza, hunyoro hwemugwagwa, nezvimwewo, nzvimbo yacho inowanzoda kugadzirisa slurry zvinoenderana nemamiriro chaiwo. Kuwanda kwemvura inoshandiswa mumusanganiswa we slurry inogadziriswa zvishoma kuti ichengetedze kuwirirana kwemusanganiswa wakakodzera paving zvinodiwa.
(3) Micro-surface demulsification nguva yekudzora
Munguva yenzira yekuvaka micro-surfacing yekuvaka, chikonzero chakakosha chezvinetso zvemhando yepamusoro ndechekuti nguva ye demulsification yemusanganiswa we slurry ichangotanga.
Ukobvu husina kuenzana, makwara, uye kusabatana kweasphalt kunokonzerwa nedemulsification zvese zvinokonzerwa nekukasika demulsification. Mukutaura kwechisungo pakati pechisimbiso chekuvhara uye nzira yemugwagwa, premature demulsification ichave yakaipisisa zvikuru kwairi.
Kana zvikaonekwa kuti musanganiswa wacho wakaitwa demulsified nguva isati yakwana, chiyero chakakodzera chekudzorera chinofanira kuwedzerwa kuti chishandure chiyero chekuzadza. Uye batidza pre-yakanyorova mvura switch kuti udzore nguva yekupwanya.
(4) Kudzora kwekuparadzanisa
Munguva yekugadzira migwagwa mikuru, kupatsanurwa kunoitika nekuda kwezvikonzero zvakaita sekutetepa paving ukobvu, gobvu musanganiswa gradation, uye yekumaka mutsara chinzvimbo (yakapfava uye nehumwe ukobvu).
Munguva yekugadzira, zvinodikanwa kudzora ukobvu hwepaving, kuyera ukobvu hwepaving munguva, uye kugadzirisa panguva yakakodzera kana paine zvikanganiso zvakawanikwa. Kana kukwidziridzwa kwemusanganiswa kwakanyanyisa, kukwidziridzwa kwe slurry musanganiswa kunofanira kugadziriswa mukati mechikamu chekugadzirisa kuvandudza chiitiko chekuparadzanisa pa micro surface. Panguva imwecheteyo, mitsara yemugwagwa inofanira kugadzirwa inofanira kugayiwa isati yaiswa.
(5) Kudzora kwemugwagwa paving ukobvu
Mukugadzira nzira dzemigwagwa mikuru, ukobvu hwekugadzira hwemusanganiswa wakatetepa hunosvika 0.95 kusvika 1.25 nguva. Mugiredhi renji, curve inofanirawo kunge iri padyo nedivi rakakora.
Kana chikamu chezvikamu zvakakura muhombekiti yakakura, inofanira kuiswa zvakanyanya, kana zvikasadaro zvikamu zvakakura hazvigoni kumanikidzirwa muvharo yekuisa chisimbiso. Uyezve, zvakare zviri nyore kukonzera mavanga pane scraper.
Kusiyana neizvi, kana muunganidzwa wakanyatsonaka panguva yekuenzanisa, ipapo mugwagwa wakarongwa unofanirwa kuve wakatetepa panguva yekugadzira nzira.
Munguva yekuvaka, kukora kwepaving kunofanirwawo kudzorwa uye kuyedzwa kuti ive nechokwadi chehuwandu hwemusanganiswa weslurry unoshandiswa mumigwagwa mikuru. Mukuwedzera, panguva yekuongorora, vernier caliper inogona kushandiswa kuyera zvakananga slurry chisimbiso pane micro-pamusoro pemugwagwa uchangoburwa. Kana ikadarika humwe hukobvu, bhokisi repavhari rinofanira kugadziriswa.
(6) Kudzora kutaridzika kwemugwagwa
Kune micro-surface paving mumigwagwa mikuru, kusimba kwemaitiro emugwagwa kunofanirwa kuongororwa pachine nguva. Kana kusununguka, masaisai, kushaya simba, makomba, matope, uye makatsemuka zvikaonekwa, aya mamiriro emigwagwa anofanira kugadzirwa asati avhara kuvaka.
Munguva yekugadzira, iva nechokwadi chekuichengeta yakatwasuka uye ive nechokwadi chekuti ma curbs kana migwagwa yakaenzana. Pamusoro pezvo, pakugadzira, hupamhi hwekugadzira hunofanirawo kuverengerwa, uye majoini anofanirwa kuiswa zvakanyanya sezvinobvira pamutsetse wekuparadzanisa mutsara kuti udzore kugadzikana kwekusanganiswa uye kudzivirira izvo zvinhu kubva kupatsanurwa nguva isati yakwana mubhokisi rekugadzira kuti ive nechokwadi chekuti. ndivo Huwandu hwemvura panguva muitiro iri kunyange uye pakati nepakati.
Uye zvakare, zvinhu zvese zvinofanirwa kutariswa panguva yekurodha kuti ibvise zvidimbu zvakakura, uye hurema hunofanirwa kukwenenzverwa nenguva panguva yekuzadza kuitira kuti chitarisiko chavo chive chakatsetseka uye chinoenderana.
(7) Kudzora kwekuvhura traffic
Iyo bvunzo mamaki yeshangu inzira inowanzoshandiswa yekuongorora yemhando yekuvhura mugwagwa panguva yemicro-pamusoro pekugadzirisa mugwagwa. Kureva kuti, isa huremu hwemunhu pamudzi kana pasi peshangu womira pachisimbiso kwemasekondi maviri. Kana iyo aggregate isina kuburitswa kunze kana kunamira kune shangu yemunhu kana ichisiya yekuisa chisimbiso chepamusoro, inogona kutorwa senge micro surface. Mushure mekunge basa rekugadzirisa rapera, rinogona kuvhurwa kune traffic.
