Asphalt Paver Screed hauv qab phaj sib dhos nrog rau cov cua sov Rods Screed Phaj thiab Tamper Bars
Lub screed hauv qab phaj, nrog rau lub ntsiab screed phaj sib dhos, ua rau lub screed phaj sib dhos ntawm ib qho asphalt paver. Lub screed hauv qab phaj txuas mus rau hauv qab ntawm lub ntsiab screed phaj thiab ua ke lawv pab theem, du, thiab compact asphalt khoom thaum nws tawm hauv paver. Txuas rau hauv qab phaj yog cov khoom tseem ceeb, nrog rau cov cua sov, tamper bar, thiab siab bar. Lub hom phiaj tseem ceeb ntawm screed hauv qab phaj yog kom ruaj ntseg txhua qhov yuav tsum tau ua kom zoo compaction thiab smoothing ntawm asphalt khoom. Lub phaj steel muab cov khoom ruaj khov, ruaj khov uas tuaj yeem tiv taus qhov kub thiab txias. Cov cua sov rods txuas ncaj qha mus rau hauv qab ntawm cov hlau phaj kom sov cov screed daim hlau mus rau qhov xav tau paving kub. Lub tamper bar yog steel bar uas mounted rau hauv qab heev ntawm screed hauv qab phaj. Nws ua hauj lwm kom ntxiv compact thiab du cov ntaub ntawv asphalt thaum nws hla hauv qab screed. Lub siab bar nrog lub hydraulic pulsing system generates high density compaction cuam tshuam rau pavement nyob rau hauv paving, thiab nws yuav tsum tau tiv taus loj loj kev nyuaj siab thaum lub sij hawm tus txheej txheem.
Cov khoom siv tes ua asphalt paver screed hauv qab phaj sib dhos tuaj yeem ua tau zoo rau yuav luag txhua hom nrov asphalt pavers, xws li VOGELE, DYNAPAC, CAT thiab lwm yam. Cov khoom siv txuas nrog cov screed hauv qab phaj ua haujlwm ua ke kom sib kis tau zoo, compact, thiab kev ntxhib los mos ntawm cov khoom siv asphalt. Cov rhuab screed daim hlau sov lub asphalt mus rau qhov kub thiab txias rau kev ua haujlwm. Cov vibrators ceev ceev cov khoom siv hauv qab screed. Thaum kawg, lub tamping bar muab qhov pib nto kev ntxhib los mos thiab compaction raws li lub asphalt tawm ntawm hauv qab lub screed. Los ntawm kev txuas ntau yam uas yuav tsum tau ua rau paving rau lub phaj hauv qab, lub phaj pab ua kom lub screed sib dhos ua tiav nws txoj haujlwm. Lub phaj hauv qab, nrog rau lub ntsiab screed phaj, ua rau lub plawv ntawm lub screed system. Nws cov khoom ua haujlwm ua ke kom ua tiav qhov tseem ceeb paving yuav tsum tau ntawm longitudinal joint compaction, nto smoothness, pavement qhov tob tswj, thiab nto zoo nkauj raws li cov ntaub ntawv asphalt ntws nyob rau hauv lub haib screed phaj sib dhos thaum lub sij hawm ua hauj lwm paving.
