1. Nzvimbo yekuvaka: inodiwa kubatanidza, kuenzanisa uye kubvisa zvinhu zvakapinza uye zvakabuda.
2. Kuiswa kweGridhi: panzvimbo yakati sandara uye yakamanikana, iyo huru yekusimbisa kutungamira (longitudinal) yegidhi yakaiswa ichave yakamira.
Munzira yeaxis yekumisikidza, iyo pavement ichave yakati sandara, isina makwinya, uye yakasungwa zvakanyanya sezvinobvira.Paved lattice yakagadzikwa nedowels uye pasi nedombo ballast
Iyo huru yekushushikana inotungamira inofanirwa kuve yakazara hurefu husina mubatanidzwa, uye kubatana pakati pemaamplitudes kunogona kusungwa nemaoko uye kupindirana, uye hupamhi hwepamusoro haufanire kunge hushoma pane.
10cm. Kana iyo grid yakaiswa mune anopfuura maviri akaturikidzana, majoini ari pakati pematanho achadzika.Mushure mekuisa nzvimbo yakakura, gadzirisa flatness yayo yose
Madhigirii.Mushure mekunge ivhu razadzwa uye risati rakunguruka, gidhi richadzokororwa zvakare nematurusi kana maturusi emuchina, uye simba richava rakaenzana, kuitira kuti gidhi rive.
Ivhu riri mumamiriro ezvinhu akatwasuka.
3. Kusarudzwa kwekuzadza: filler ichasarudzwa maererano nezvinodiwa zvekugadzira.Kudzidzira kwakaratidza kuti kuwedzera kune ivhu rakaomeswa nechando, ivhu remarara, marara epamba
Chaki 10 uye diatomite inogona kushandiswa semazadza.Nekudaro, iwo ma mechanic properties yevhu rine gravelly uye jecha ivhu rakagadzikana, uye rinokanganiswa zvishoma nemvura.
Zviri nani.Iyo particle size ye filler haifanire kunge yakakura kupfuura 15cm, uye kutarisisa kuchabhadharwa kudzora magiredhi eiyo filler kuti ive nechokwadi chekugadzirisa huremu.
4. Paving uye compaction yekuzadza: mushure mekunge grid yaiswa uye yaiswa, ichazadzwa uye yakavharwa nenguva, uye nguva yekuratidzwa haingapfuuri maawa makumi mana nemasere.
Iyo yekuyerera nzira yekuisa uye yekudzosera kumashure inogona kugamuchirwa.Pave filler pamigumo miviri kutanga, gadzirisa grid, uye woisundira wakananga pakati
Enter.The rolling sequence kubva kumativi maviri kusvika pakati.Munguva yekukunguruka, iyo roller haifanire kubata iyo yekusimbisa zvakananga, uye iyo isina kusimba yekusimbisa inowanzo.
Mota hadzibvumidzwe kutyaira pairi kudzivirira kubviswa kwekusimbisa.Iyo layer compaction degree ndeye 20-30cm.Iyo compactness inofanirwa kusangana nezvinodiwa zvekugadzira
Iyi ndiyo zvakare kiyi yekubudirira kweinjiniya yevhu yakasimbiswa.
5. Matanho ekudzivirira mvura uye emvura: muinjiniya yevhu yakasimbiswa, kurapwa kwemvura mukati nekunze kwemadziro kunofanira kuitwa zvakanaka;Ita basa rakanaka rekudzivirira tsoka nekudzivirira
Scour;Sefa nematanho ekudonha achaiswa muhuwandu hwevhu.Kana zvichidikanwa, geotextile uye pombi inopindika (kana gomba remapofu) ichaiswa kuti ibvise mvura munzira yekudonha, iyo isingazovharwe, zvikasadaro njodzi yakavanzika ichaitika.
