Pakati pematanho ekuvaka emigwagwa yakapedzwa uye yakarongwa, inodarika 95% ndeye semi-rigid base asphalt pavements. Iyi nzira yemugwagwa ine zvakanakira maringe nemutengo wekuvaka uye kutakura mitoro, asi inowanzoitika kune makatsemuka, kusunungura, slurry, uye voiding. , subsidence, insufficient subgrade simba, subgrade slippage uye zvimwe zvirwere zvakadzika. Hazvisi nyore kurapa zvirwere zvemumigwagwa zvakadzika. Urongwa hwekugadzirisa hwechinyakare hunowanzo: usarapa zvirwere zvakadzika-munguva yekutanga uye urege kuti zvikure; apo zvirwere zvakadzika zvakadzika kusvika kune imwe nzvimbo, zvifukidze kana kuwedzera nzira; uye kana hosha dzakadzika-dzika dzakakomba zvekuti dzinogona kukanganisa traffic, Wobva waita kurapwa kwekuchera, kureva, echinyakare yakakura uye yepakati-saizi kugadzirisa kuvaka, uye zvipingamupinyi zvinounza zvakare zviri pachena, senge mutengo wakakwira, tsvina yakakomba, kukanganisa pamotokari, kukanganisa kwezvakatipoteredza, nezvimwewo. Mumamiriro ezvinhu akadaro, kuwedzera hupenyu hwebasa remigwagwa, kuderedza mutengo nemarara zvinokonzerwa nekugadzirisa migwagwa, uye kuvandudza kunaka kwemigwagwa kwave kutenderera kutsva kwemisoro.
Nekukurumidza kukura kwesainzi uye tekinoroji, mukupindura kumatambudziko ari pamusoro apa, pfungwa yedu yakakosha ndeyekusimbisa zuva nezuva kudzivirira kuchengetedza kwemigwagwa, kuona kwezvirwere zvakadzika, uye kurapwa kwezvirwere zvakadzika.
Kudzivirirwa kugadziridzwa kwepavement ndeye yakarongwa inogadziridza gadziriso yepavement kana iyo pavement chimiro chakanyatso kurongeka uye iyo pavement mamiriro ichiri kusangana nezvinodiwa zvinoshanda. Yakasiyana neyechinyakare yekuchengetedza musimboti we "usagadzirise mugwagwa kana usina kuputsika", kudzivirira kuchengetedza kweasphalt pavement kunobva pane fungidziro yekuti iyo yekutanga pavement chimiro hachizoshandurwe zvakanyanya, uye haina chinangwa chekuvandudza simba re nzira yakarongwa. Kana pasina kukuvadzwa kuri pachena kwegwagwa kana zviratidzo zvidiki zvechirwere, kana zvichifanoona kuti zvirwere zvinogona kuitika uye mamiriro emumugwagwa achiri kusangana nezvinodiwa zvekushanda, ita zvakarongwa proactive kugadzirisa pamusoro pemugwagwa.
Chinangwa chekudzivirira kuchengetedza kweasphalt pavement ndechekuchengetedza mabasa akanaka epavement, kunonoka kudzikisira kuita kwepavement, kudzivirira kuitika kwezvirwere zvepavhu kana kuwedzera kuwedzera kwezvirwere zvidiki uye zviratidzo zvechirwere; kuwedzera hupenyu hwebasa repavhu, kuderedza kana kunonoka kugadzirisa nekuchengetedza zvirwere zvepavement; Mari yese yekugadzirisa yakaderera mukati mehupenyu hwese hwepavement. Kuzivikanwa uye kushandiswa kwekuchengetedza kwekudzivirira kwakawana mhedzisiro ye "kugadziridza kushoma" kuburikidza "nekutanga kugadzirisa" uye "kushoma kwekudyara" kuburikidza ne "kudyara kwekutanga".
Izvo zvakapesana neiyo trenchless kurapwa tekinoroji yechirwere chakadzika tekinoroji yekuchera. Tekinoroji yekuchera ndiyo inowanzoshandiswa kurapwa tekinoroji kune yakadzika mugwagwa zvirwere uye inowanzova nzira yekurapa inongoitwa. Sezvo base layer iri pazasi pedenga repamusoro, iyo yechinyakare nzira yekurapa inoda kuchera kunze kweiyo layer isati yagadzirisa base layer. Sezvambotaurwa pamusoro apa, nzira iyi haingotori nguva yakareba yekuvaka, asi inodawo kuvhara kwemigwagwa, iyo ine simba guru munzanga uye hupfumi. Nokudaro, haisi nyore kuishandisa, uye inogona kurapwa chete kana zvirwere zvakadzika-muzasi zvakakura kuva zvirwere zvakanyanya kana zvirwere zvakakomba pamusoro pepamusoro. Tekinoroji yekurapa isina trenchless yezvirwere zvakadzika-yakadzika yakaenzana ne "minimally invasive kuvhiya" munharaunda yekurapa. Nzvimbo yose ye ??"maronda" pakurapa zvirwere zvemumugwagwa kazhinji haipfuuri 10% yenzvimbo yese ye ??chirwere. Nokudaro, inokonzera kukanganisa kuduku kumugwagwa, uye nguva yekuvaka ipfupi uye inodhura. Yakaderera, haina zvayakanganisa pakufamba kwemumugwagwa, uye inochengetedza zvakatipoteredza. Iyi tekinoroji yakanangana nehunhu hwe semi-yakaomesesa migwagwa zvirwere uye yakanyatsokodzera kurapa zvakadzika midzi mumigwagwa yenyika yangu. Muchokwadi, "Technical Regulations for Trenchless Treatment of Deep Road Diseases" isati yaziviswa, tekinoroji yekurapa yakadzika yezvirwere zvemumigwagwa yakashandiswa kakawanda munyika yose uye yakawana mhedzisiro yakanaka.
Iko kusimudzira kwakasimba kweindasitiri yekugadzirisa migwagwa hakuna kupatsanurwa kubva kune tekinoroji uye pfungwa yekuvandudza. Mukuita kwekuvandudza, izvo zvinowanzotitadzisa hakusi kuti mazano uye matekinoroji pachawo akanaka here, asi kuti isu tinotsunga kupaza zvipingaidzo zvemuenzaniso wekutanga. Zvichida haina kufambira mberi zvakakwana uye inoda kuvandudzwa zvishoma nezvishoma mune ramangwana rekushandisa, asi isu tinofanira kutsigira nekukurudzira hunyanzvi.
