Cement kongiri pavement inzira yakajairika parizvino.Chete nekunyatso simbisa kusimba, kupfava uye kupfeka kuramba, kunogona kuwanikwa kwemhando yepamusoro traffic.Iri bepa rinoita ongororo yakazara pakuvakwa kwesamende kongiri pavement kuitira kuti ivandudze kushanda kwayo uye kuzadzisa zvinodiwa zvemhando yepamusoro.
Pavement engineering ndiyo inonyanya kukosha chikamu chekugadzira migwagwa engineering.Haisi kungoshandisa zvinhu zvakawanda, asiwo ine maitiro akaoma.Kana ikasabatwa zvakanaka, matambudziko achaitika, anokanganisa kuchengetedzwa kwemigwagwa.Mhedzisiro yakanangana nekusarongeka kwepavement kurapwa ndeyekuti zvimiro zvine hunyoro zvichagadzirwa nekuda kwekuchinja kwekunze kwekunze tembiricha, zvichikonzera matambudziko akasiyana emhando yepavement.Matunhu akasiyana anofanirwa kunyatsosarudza fomu repavement zvinoenderana nekwavanogara, uye nekunatsiridza kugona kwekuziva kwepavement raw material kusarudzwa, giredhi rekugadzira dhizaini, bvunzo yekuongorora, kudzora maitiro ekuvaka, danho rekuita, tekinoroji tekinoroji, nharaunda yekuvaka, nezvimwe. ., kuitira kuisa hwaro hwekuvakwa kwemigwagwa mikuru yemhando yepamusoro.Parizvino, iyo yakajairika pavement ndeye simende kongiri pavement, iyo ine kugadzikana kwakanyanya nekuda kwekumanikidza kwayo, kukotama uye abrasion kuramba.Panguva imwecheteyo, rudzi urwu rwekufamba kune zvakawanda zvakanakira, sehupenyu hurefu hwebasa, mari shoma yemazuva ese yekugadzirisa, uye inobatsira kutyaira husiku.Kuti ive nechokwadi chekuti simende kongiri pavement inogona kuita basa rayo rakakodzera, inoda dhizaini yakanyatso uye kuvaka kwakasimba, kuitira kuti ive nechokwadi chemhando uye kupa kutamba kune zvakanakira simende pavement.
Kusarudzwa kwemvura yekuwedzera:
Kuvaka simende kunoda zvimwe zvakasanganiswa, izvo zvinogona kuvandudza kusimba uye kuoma kwe simenti.Iwo admixtures anonyanya kusanganisira mvura inodzikisa agent, fluidizing agent uye zvimwe zvinhu.Nekusanganisa nesamende, kusimba kwekongiri kunogona kuvandudzwa zvizere.Mvura yakachena isina tsvina ichasarudzwa kuti ishandiswe.Mvura ine tsvina haigoni kushandiswa, iyo inokanganisa kuoma kwe simenti.
Pesvedzero yekuwedzera huwandu pane kongiri inodonha:
Kuwedzera chinhu chakakosha.Huwandu hwayo hune simba guru pane kongiri inodonha uye chimwe chezvinhu zvikuru.Kuwedzera chinhu chinokonzeresa kusimudzira muviri uye makemikari zvimiro zvekongiri.Zvakawanda kana zvishoma hazvizobudisi zvibereko zvakanaka.
Pesvedzero yekuchinja kwegiredhi pane kudonha kwekongiri:
Shanduko yegiredhi ichakanganisa kudonha kwekongiri kusvika pamwero mukuru.Kana magiredhi asina kukodzera, matambudziko emhando yekuvaka anoitika.Nemvura yakafanana uye mvura simende reshiyo, kudonha kwefine aggregate kongiri idiki uye yakagadzikana kupfuura iyo coarse aggregate kongiri.Munguva yekusanganisa kongiri, zvinodikanwa kudzora kudyisa kweaggregate bin kuti ive nechokwadi chekugadzikana kweaggregate grading yebhini rega rega.
