Malo omanga
(1) Ntchito yomanga imachitika m'malo omwe kutentha kwa mpweya sikutsika kuposa 5 ℃ ndipo kutentha kwa msewu sikutsika kuposa 10 ℃;
(2) Pamwamba pa msewu womangayo uyenera kukhala waukhondo, wouma, komanso wafulati. Pambuyo pa mvula, msewu uyenera kukhala wouma kwa maola osachepera 24 musanamangidwe;
(3) Malo otsetsereka a asphalt amatha kumangidwa maola 10 atayikidwa ndipo phula lakhazikika. Njira yatsopano ya simenti imatha kumangidwa patatha masiku 20 itayalidwa ndikutsegulidwa kuti anthu aziyenda.
Njira zogwiritsira ntchito ndi masitepe
(1) Kuyeretsa misewu: Pamwamba pa msewu uyenera kuyeretsedwa musanamangidwe. Pali zinthu zoyandama ndi tiziduswa tating'ono tosavuta kugwa pamsewu.
Gwiritsani ntchito burashi yawaya kuti muyiyeretse musanamangidwe;
(2) Ikani zoyambira: Tsegulani chophimba chomatira ndikugwedeza mofanana; gwiritsani ntchito chodzigudubuza cha velveti chosagwirizana ndi zosungunulira kapena burashi kuti mugwiritse ntchito zomatira pansi mofanana ndi makulidwe apakati. Mukamagwiritsa ntchito, zomatira ziyenera kukhala 2-3 masentimita kupitirira m'lifupi mwa mzere wolembera kapena chizindikiro. Pogwiritsira ntchito guluu pansi, mphamvu inayake iyenera kugwiritsidwa ntchito kuti zitsimikizire kuti guluu wosanjikiza ndi nthaka ikhoza kulowetsedwa mokwanira, makamaka guluu pamakona a chizindikirocho chiyenera kugwiritsidwa ntchito; kutengera makulidwe ndi kufanana kwa guluu, mutatha kugwiritsa ntchito bwino Siyani kuti ziume kwa mphindi 5-10 musanaphatikize.
(3) Kupaka kukatsirizika, chithandizo cha kupanikizika chiyenera kuchitidwa ndi kugubuduza ndi zinthu zolemera, kumenya ndi nyundo ya rabara, ndi kukanikiza pamanja. Makamaka, ngodya za chizindikirocho ziyenera kumenyedwa mosamala kuti zitsimikizire kuti pamwamba pamakhala kugwirizana kwathunthu. Ngati zinthu zilola, zotsatira zake zikhala bwino ngati magalimoto amadutsa pang'onopang'ono pa tepi yomata. Kutentha kozungulirako kukakhala kocheperako, tepiyo kapena chizindikirocho chiyenera kuphikidwa ndi blowtorch kapena moto wa gasi wothira madzi kenako ndikuumirizidwa kuti mupeze zotsatira zabwino.
(4) Pambuyo polumikizana molingana ndi njira yomwe ili pamwambayi, imatha kutsegulidwa kumayendedwe mwachizolowezi. Komabe, zomatirazo sizinafikire mphamvu yolumikizana bwino kwambiri pakadali pano. Nthawi zambiri, yesetsani kupewa kung'amba ndi kusenda mwamphamvu mkati mwa maola 48.
(5) Ngati chizindikirocho kapena chizindikirocho chili ndi chotupa chapafupi, zikutanthauza kuti mphira ya rabara sinasiyidwe yotseguka kwa nthawi yokwanira kapena mpweya sunathe. Mutha kugwiritsa ntchito chida chakuthwa kuboola chotupacho, kutulutsa mpweya, ndikuupanikizanso.
Zinthu zoti muzindikire
(1)Mukamanyamula, kusunga ndi kugwiritsa ntchito mankhwalawa, chonde sungani kutali ndi komwe kuli moto kapena malo otentha kwambiri ndipo yesetsani kuonetsetsa kuti mpweya wabwino ukuyenda bwino.
(2) Pambuyo pa zomatira zomwe zimagwiritsidwa ntchito pa mankhwalawa, chivundikirocho chiyenera kusindikizidwa nthawi yake kuti chosungunulira chisasunthike komanso kukhala viscous kwambiri, zomwe zimapangitsa kuti zikhale zovuta kugwiritsa ntchito.
(3)Matepi ounikira opangidwa ndi misewu ndi zizindikilo zimakhala zogwira mtima kwa nthawi yayitali popanda zoyambira kukhala zolimba. Zomatira zomwe zimagwiritsidwa ntchito mu mankhwalawa zimakhala ndi alumali moyo wa chaka chimodzi. Ngati ipitilira nthawi ya alumali, iyenera kuyesedwa musanagwiritse ntchito.
