Ma geomembranes amagwiritsidwa ntchito kwambiri pamakina apamisewu. M'zaka zaposachedwa, ma geomembranes akhala akugwiritsidwa ntchito kwambiri pamapulojekiti omwe ndakumana nawo. Ma geomembranes amagwiritsidwa ntchito popanga miyala. Ikhoza kuchepetsa kapena kulepheretsa ming'alu yachiwonetsero cha msewu wakale wa phula poyendetsa pansi pa phula pamwamba pa phula lakale la phula ndi misewu yakale ya simenti kapena pansi pa phula pamwamba pa misewu yatsopano.
Zimachepetsanso kung'ambika komanso kutentha pang'ono pamapando a asphalt ndikuwongolera moyo wautumiki wapanjira. Mipando ya phula ndi konkriti ya simenti ndiye njira zazikulu zopangira misewu yapamwamba, ndipo ndi ntchito ziwiri zamakina zamakina.
Pali mitundu iwiri yamiyala ya phula: mayendedwe a phula osinthika pansi ndi phula lokhazikika pansi. M'masiku oyambirira, kumanga kwakukulu kunali pansi kosinthika. M'zaka zaposachedwa, ndikukula kwa magalimoto, zomangamanga zazikuluzikulu ndizomwe zimakhazikika pamiyala ya asphalt. Njirayi yakhala ikugwiritsidwa ntchito kwa nthawi yayitali.
Kuwonongeka kwamapangidwe ndi magwiridwe antchito monga kusweka koyima ndi kopingasa, kupukuta, kuyika bwino, kukana kutsetsereka, ndi zina zambiri kumachitika ndikuwongolera pogwiritsa ntchito zosakaniza za asphalt. Vuto lalikulu kwambiri la pulojekiti yamtundu wotereyi ndilowonekera mofulumira kwa ming'alu kuchokera kumalo oyambirira kupita kumalo okwerapo {1 nthawi zambiri zaka 2 mpaka 3}, zomwe zimayambitsa kuwonongeka kwa kapangidwe kawo.
Simenti konkire m'misewu ntchito mu nthawi yotsatira adzaonekanso 1 gulu la kuwonongeka structural ndi zinchito, makamaka m'misewu olowa mafuta kondomu ndi apezeka ngati tsopano, nthawi zambiri ntchito njira ya phula osakaniza pamwamba chivundikirocho, koma poganiza kuti msewu olowa si. kuchitiridwa, ndithudi kudzawoneka mu maonekedwe a msewu, kufupikitsa moyo wa khungu wosanjikiza.
Watsopano anamanga khwalala deta theka-olimba subgrade, osauka konkire subgrade deta kufupikitsa mng'alu kapena kukulitsa msoko, nayenso tsopano ndi vuto lalikulu, mmene kuchepetsa ming'alu, kupewa kuyatsa pamwamba ming'alu kuwombera, chomwe ndi chinsinsi Rhine mkulu khalidwe lapamwamba. Tsopano, gulu la mainjiniya lakhala likuyang'ana zatsopano kuti athe kuthana ndi vutoli mwachuma. Monga momwe tikuonera, mu nkhani iyi, nembanemba zofukulidwa zikugwiritsidwa ntchito panjira yodutsamo ndi zotsatira zabwino.
Zomwe zili pamwambazi zitha kuwoneka kuti ma geomembranes amagwiritsidwa ntchito kwambiri ndipo amathanso kuchepetsa ming'alu yowonekera pamtunda wamtunda wa msewu. Ngati muli ndi zosowa zamtundu uliwonse, tiyimbireni zambiri ndipo tidzakupatsani malangizo oyenera!
