Zomangamanga za Mayendedwe
Ndi chitukuko cha sayansi ndi ukadaulo, ma geosynthetics akugwiritsidwa ntchito kwambiri popanga misewu. Mwachitsanzo: mu khoma losungiramo msewu waukulu, chitetezo cha malo otsetsereka, ndi zina zotero, makamaka pokonza ngalande zofewa za nthaka, ming'alu ya pamwamba pa msewu, ndi madera ena ogwiritsidwa ntchito, chifukwa cha mtundu wapadera wa zinthu za geosynthetic zomwe zili nazo, zimagwira ntchito yofunika kwambiri pakupanga misewu, ndipo ma geotextiles ndi omwe amagwira ntchito kwambiri pakupanga misewu. Nthawi zambiri amagwiritsidwa ntchito popanga misewu, amathandiza kudula gawo lopyapyala pamwamba, komanso ming'alu yotsutsana ndi kuwunikira.
Geonet ili ndi malo abwino olumikizirana ndi subgrade filler, imatha kulimbitsa mphamvu ya subgrade, kupewa kutayika kwa nthaka yotsetsereka, yomwe imagwiritsidwa ntchito makamaka popangira subgrade, komanso kuteteza embankment. Pofuna kukonza kukhazikika kwa embankment yapadera, kupewa kukhazikika kwa embankment, zida zopangira geosynthetic zitha kugwiritsidwa ntchito kulimbitsa embankment.
Pa nthawi yomanga, malo ozungulira, malo ozungulira, malo ozungulira, ndi zina zotero amagwiritsidwa ntchito kwambiri. Pambuyo poti malo ozungulira alimbikitsidwa, njira yolumikizirana yomwe imapangidwa ndi malo opingasa olimba ndi zinthu zodzaza imafanana ndi njira yolumikizirana ya zinthu zodzaza, kotero kuti mphamvu yodula ya malo ozungulira imakulitsidwa. Kukhazikika ndi mphamvu ya malo ozungulira ndi malo ozungulira zimagwirizana kwambiri ndi madzi. Pakumanga ndi kukonza malo ozungulira ndi malo ozungulira, madzi ozungulira ayenera kuchitidwa bwino, zomwe ndi njira yofunika kwambiri yotsimikizira kukhazikika kwa malo ozungulira ndi malo ozungulira. Pakumanga misewu, ma geosynthetics amagwira ntchito ndi nyumba zina zotulutsira madzi kuti apange njira yotulutsira madzi.
