Chingwe chachindunji chokwiriridwa chowoneka bwino chimakhala ndi tepi yachitsulo kapena waya wachitsulo kunja, ndipo chimakwiriridwa pansi.Pamafunika ntchito kukana kunja mawotchi kuwonongeka ndi kupewa dzimbiri nthaka.Zomangamanga zosiyanasiyana za sheath ziyenera kusankhidwa molingana ndi momwe zimagwiritsidwira ntchito komanso momwe zinthu zilili.Mwachitsanzo, m’madera okhala ndi tizirombo ndi makoswe, payenera kusankhidwa chingwe chounikira chokhala ndi m’chimake chomwe chimalepheretsa kuti tizirombo ndi makoswe zisalumidwe.Kutengera mtundu wa dothi ndi chilengedwe, kuya kwa chingwe cha kuwala chokwiriridwa pansi nthawi zambiri kumakhala pakati pa 0.8m ndi 1.2m.Poika, kusamala kuyeneranso kuchitidwa kuti mphamvu ya fiber ikhale mkati mwa malire ovomerezeka.
Maliro achindunji ayenera kukwaniritsa zofunikira izi:
1. Pewani madera omwe ali ndi asidi amphamvu ndi dzimbiri zamchere kapena zowonongeka kwambiri ndi mankhwala;pamene palibe njira zodzitetezera, pewani madera owonongeka ndi chiswe ndi malo omwe amakhudzidwa ndi kutentha kapena malo omwe amawonongeka mosavuta ndi mphamvu zakunja.
2. Chingwe cha kuwala chiyenera kuikidwa mu ngalande, ndipo malo ozungulira a chingwe cha kuwala ayenera kuphimbidwa ndi dothi lofewa kapena mchenga wosanjikiza wosachepera 100mm.
3. Pafupi ndi kutalika kwa chingwe cha kuwala, mbale yotetezera yokhala ndi m'lifupi mwake osachepera 50mm kumbali zonse za chingwe cha kuwala chiyenera kuphimbidwa, ndipo mbale yotetezera iyenera kupangidwa ndi konkire.
4. Malo oyikapo ali m'malo omwe amakumba pafupipafupi monga misewu yopita kumizinda, yomwe imatha kuikidwa ndi malamba okopa maso pa bolodi lachitetezo.
5. Pamalo ogona m'madera ozungulira kapena pamalo otseguka, pamtunda wowongoka wa pafupifupi 100mm panjira ya chingwe cha kuwala, potembenuka kapena gawo limodzi, zizindikiro zowonekera bwino ziyenera kukhazikitsidwa.
6. Mukayika m'madera osazizira, chingwe cha kuwala kwa maziko a pansi pa nthaka sichiyenera kukhala osachepera 0.3m, ndipo kuya kwa chingwe cha kuwala pansi sikuyenera kukhala pansi pa 0.7m;ikakhala panjira kapena malo olimidwa, iyenera kuzama bwino, ndipo isakhale yosachepera 1m.
7. Mukayika m'nthaka yachisanu, iyenera kukwiriridwa pansi pa nthaka yachisanu.Pamene sichikhoza kukwiriridwa mozama, ikhoza kukwiriridwa mu nthaka youma yozizira kapena nthaka yodzaza ndi nthaka yabwino, komanso njira zina zotetezera kuwonongeka kwa chingwe cha kuwala zingathe kuchitidwanso..
8. Pamene mizere ya chingwe cha kuwala yokwiriridwa mwachindunji imadutsana ndi njanji, misewu yayikulu kapena misewu, mipope yotetezera iyenera kuvala, ndipo chitetezo chiyenera kupitirira malire a msewu, mbali zonse ziwiri za msewu ndi mbali ya ngalande ya ngalande ndi kupitirira 0.5m.
9. Pamene chingwe cha kuwala chokwiriridwa mwachindunji chikulowetsedwa mu dongosolo, chubu chotetezera chiyenera kukhazikitsidwa pa dzenje lotsetsereka, ndipo mphuno iyenera kutsekedwa ndi madzi.
10. Mtunda woonekera bwino pakati pa mgwirizano wa chingwe choyang'ana chokwiriridwa mwachindunji ndi chingwe choyang'ana chapafupi sichiyenera kukhala chochepera 0.25m;malo ophatikizana a zingwe zofananira zowonera ziyenera kugwedezeka kuchokera kwa wina ndi mnzake, ndipo mtunda womveka suyenera kukhala wochepera 0.5m;malo olowa pa malo otsetsereka ayenera kukhala yopingasa;kwa mabwalo ofunikira Ndikofunikira kusiya njira yopuma kuti muyike chingwe chowunikira mdera lanu kuyambira pafupifupi 1000mm mbali zonse za chingwe cholumikizira chingwe.
