Slurry sealing ndiyo inosimudzira tekinoroji mukugadzirisa migwagwa. Haigoni kungozadza uye kusapinda mvura, asiwo kuva anti-slip, kupfeka-resistant uye kupfeka-resistant. Saka nehunyanzvi hwakadai hwekuvharisa tekinoroji yekuvaka, ndedzipi dziviriro dzinoda kutariswa panguva yekuvaka?
Iyo slurry chisimbiso chinoshandisa zvakakodzera giredhi matombo machipisi kana jecha, mafirita, emulsified asphalt, mvura, uye ekunze zvinosanganiswa kugadzira inoyerera asphalt musanganiswa wakasanganiswa mune imwe chikamu. Iyo asphalt seal inopararira zvakaenzana munzira yemugwagwa kuti iite asphalt seal layer.

Zvinhu zvishanu zvakakosha zvekucherechedza:
1. Tembiricha: Kana tembiricha yekuvaka yakadzikira kupfuura 10 ℃, emulsified asphalt kuvaka hakuzoitwe. Kuchengeta chivakwa chiri pamusoro pe10 ℃ kunobatsira pakubvisa asphalt mvura uye kubuda kwemvura;
2. Mamiriro ekunze: Emulsified asphalt kuvaka hakuzoitwe pamhepo kana kunaya. Emulsified asphalt kuvaka ichaitwa chete kana pasi pakaoma uye pasina mvura;
3. Zvishandiso Batch imwe neimwe yeasphalt ye emulsified inofanira kuva neshumo yekuongorora kana ichibuda muhari kuti ione kuti zvinyorwa zvematrix asphalt inoshandiswa mumichina yekusanganiswa inonyatsoenderana;
4. Paving: Paunenge uchigadzira slurry seal layer, hupamhi hwemugwagwa hunofanira kugoverwa zvakaenzana mumigwagwa yakawanda yekugadzira. Upamhi hwepaving slabs hunofanira kuchengetwa zvakaenzana nehupamhi hwematanho, kuitira kuti nzira yose yemugwagwa inogona kugadzirwa nemichina uye kuzadza kwemaoko kwezviputi kuderedzwa. Panguva imwecheteyo, panguva yekugadzira, basa remaoko rinofanirwa kushandiswa kubvisa zvinhu zvakawandisa kubva pamajoini uye kuwedzera zvikamu zvisipo zvega zvega kuita kuti majoini ave akatsetseka uye akatsetseka;
5. Kukuvadza: Kana iyo slurry chisimbiso ichikanganiswa panguva yekuvhurwa kune traffic, kugadziriswa kwemaoko kunofanirwa kuitwa uye slurry chisimbiso chinofanira kutsiviwa.
Slurry sealing ndiyo tekinoroji yekugadzirisa mugwagwa nekuita kwakanaka, asi kuti tive nechokwadi chemhando yemugwagwa, isu tichiri kufanira kubhadhara zvakanyanya kune izvo zvingave zvisingatarisirwe panguva yekuvaka. Unofungei?
