1. Choyamba, fotokozani molondola mzere wotsetsereka wa bedi la msewu.Pofuna kuonetsetsa kuti m'lifupi mwa msewu, mbali iliyonse imakulitsidwa ndi 0.5m.Mukayala dothi louma, gwiritsani ntchito chogudubuza cha 25T kuti musindikize kawiri.Kenako gwiritsani ntchito kugwedezeka kwa 50T kanayi, ndikuwongolera pamanja malo osagwirizana.
2. Yambani 0.3m wandiweyani sing'anga, coarse, ndi mchenga, ndi pamanja mlingo ndi makina.Kupanikizika kosasunthika kawiri ndi chogudubuza cha 25T.
3. Ikani geogrid.Mukayika ma geogrids, pansi payenera kukhala yosalala, yowundana, komanso yosalala.Wongolani, musamangirire, musapirire, kupotoza, ndi kuphatikizira ma geogrids oyandikana ndi 0.2m.Magawo ophatikizika a ma geogrids ayenera kulumikizidwa ndi mawaya 8 # achitsulo pa mita imodzi iliyonse motsatira njira yopingasa ya bedi la msewu, ndikuyika pa ma geogrids oyikidwa.Konzani pansi ndi U-misomali pa 1.5-2m iliyonse.
4. Gawo loyamba la geogrid litayikidwa, gawo lachiwiri la 0.2m wandiweyani wapakati, wokhuthala, ndi mchenga umadzazidwa.Njira yake ndi kunyamula mchenga kupita nawo pamalo omangapo ndi kuutsitsa kumbali imodzi ya msewu, ndiyeno kugwiritsa ntchito bulldozer kukankhira kutsogolo.Choyamba, lembani 0.1m mkati mwa 2 metres mbali zonse za msewu, kenaka pindani gawo loyamba la geogrid ndikudzaza ndi 0.1m wapakati, wokhuthala, ndi mchenga.Letsani kudzaza ndi kukankhira kuchokera kumbali zonse ziwiri kupita pakati, ndikuletsa makina osiyanasiyana kudutsa ndikugwira ntchito pa geogrid popanda kudzaza, movutikira, komanso mchenga.Izi zitha kuwonetsetsa kuti geogrid ndi yafulati, osati yotupa, kapena makwinya, ndikudikirira kuti gawo lachiwiri la sing'anga, losauka, ndi mchenga lisunthike.Kuyeza kopingasa kuyenera kuchitidwa kuti mupewe makulidwe odzaza osagwirizana.Pambuyo pakuyanjanitsa popanda cholakwika chilichonse, chodzigudubuza cha 25T chiyenera kugwiritsidwa ntchito pakukakamiza kokhazikika kawiri.
5. Njira yopangira gawo lachiwiri la geogrid ndi yofanana ndi yoyamba.Pomaliza, lembani 0.3m wapakati, wokhuthala, ndi mchenga ndi njira yodzaza yofanana ndi wosanjikiza woyamba.Pambuyo pa maulendo awiri a static pressure ndi 25T roller, kulimbitsa maziko a msewu kumatsirizidwa.
6. Pambuyo pophatikizana gawo lachitatu la sing'anga, coarse, ndi mchenga, ma geogrid awiri amayikidwa motalika motsatira mzere kumbali zonse ziwiri za otsetsereka, ndikulumikizana ndi 0.16m, ndikulumikizidwa pogwiritsa ntchito njira yomweyo asanayambe ntchito yomanga nthaka.Ikani ma geogrids kuti muteteze malo otsetsereka.Mizere ya m'mphepete yoyikidwa iyenera kuyezedwa pagawo lililonse.Mbali iliyonse iwonetsetse kuti geogrid yakwiriridwa mkati mwa 0.10m kuchokera pamtunda pambuyo pa kukonzanso kotsetsereka.
7. Mukadzaza magawo awiri a dothi ndi makulidwe a 0.8m, gawo la geogrid liyenera kuikidwa mbali zonse za malo otsetsereka nthawi imodzi.Ndiye, ndi zina zotero, mpaka atayikidwa pansi pa nthaka pamtunda wa mapewa a msewu.
8. Pambuyo podzaza msewu, malo otsetsereka ayenera kukonzedwa panthawi yake.Ndipo perekani chitetezo cha zinyalala zowuma m'munsi mwa malo otsetsereka.Kuphatikiza pakukulitsa mbali iliyonse ndi 0.3m, kukhazikika kwa 1.5% kumasungidwanso gawo ili la msewu.
