Asphalt Paver Screeds Hydraulic Extending Screed Extension Mechanical Extending Screed Extension
Screed yowonjezera ndi gawo lofunikira pa phula la asphalt lomwe limalola kuti screed system ikhale yosinthika kuti ikhale yosiyana mosiyanasiyana.Kufalikira kwa screed kumamangiriza kumapeto kwa mbale yayikulu ya screed kuti iwonjezere kukula kwa screed.Zimapangidwa ndi zitsulo zopangira zitsulo zomwe zimagwirizanitsidwa ndi screed yaikulu, screed heaters ndi vibrators kuti zifanane ndi dongosolo lalikulu la screed, ndi makina a hydraulic kuti awonjezere ndi kubweza mbale za screed.Cholinga chachikulu cha screed yotalikirapo ndikupereka kusinthika kwapang'onopang'ono popanda kufunikira dongosolo latsopano la screed m'lifupi lililonse.Pogwiritsa ntchito zipilala zotalikirana zautali wosiyanasiyana, phula limodzi la phula limatha kuyala misewu ya m'lifupi mwake.Izi zimathandiza makontrakitala kugwiritsa ntchito makina amodzi pama projekiti osiyanasiyana opaka kuti apititse patsogolo mtengo komanso nthawi.Chiwombankhanga chotalikirapo chimamangirira mbali imodzi ku mbale yayikulu ya screed, ndipo mbali inayo ndi mkono wa telescopic womwe umatha kufalikira ndikubwerera.Ma mbale a screed amakonzekeretsa gawo lokulirapo ndikufananiza screed yayikulu, yokhala ndi ma heaters, vibrator, ndi tamping bar kuti igwirizane ndi zigawo zazikulu za screed.Ikatalikitsidwa mokwanira, screed yotambasula imalumikizana mosasunthika ku screed yayikulu kuti ipereke mawonekedwe ofananirako komanso opitilira muyeso kudutsa m'lifupi mwake.Kuphatikizika kwa zigawo zofananira za screed mu gawo lokulirapo kumathandizira kupitilira, kusalala kwapanjira kofananira, kachulukidwe, ndi mawonekedwe osiyanasiyana m'lifupi mwake.
Zamisiri zimatha kupereka phula loyenera bwino lomwe limawonjezera screed pafupifupi mitundu yonse yotchuka ya asphalt pavers, monga VOGELE, DYNAPAC, CAT ndi zina zambiri.Ndi kuthekera kokulitsa ndikuchepetsa dongosolo la screed kuti lifanane ndi m'lifupi mwapang'onopang'ono, phula limodzi la asphalt limapeza kusinthasintha kwakukulu komanso kusiyanasiyana.Kutha kumeneku kumapereka ndalama komanso nthawi yopulumutsa kwa makontrakitala ndi omanga misewu.Chiwombankhanga chokulirapo, pamodzi ndi msonkhano waukulu wa screed plate, umathandizira phula la asphalt kuthana ndi ntchito zambiri zopaka.Pali mitundu iwiri yowonjezera screed, imodzi ndi yamtundu wa hydraulic yomwe imapangitsa kuti pakhale m'lifupi mwake mosiyanasiyana pakati pa 1.1m ndi 9.5m, ubwino wake ndi kusinthasintha kwakukulu kwa mapaipi osiyanasiyana;ina ndi makina osasunthika amtundu wamtundu womwe umagwiritsidwa ntchito makamaka pama projekiti omanga anthawi yayitali okhala ndi m'lifupi, m'lifupi mwake ndi ma radiyo akulu chifukwa amatha kuwongolera m'lifupi mwake pakati pa 2.5m mpaka 16m pogwiritsa ntchito zomata zowonjezera za screed.
