Zofunikira pakukhazikitsa zotchinga za ngozi

Zotchinga za ngozi ndi mipanda yoyikidwa pakati kapena mbali zonse ziwiri za msewu kuti magalimoto asathamangire kuchoka pamsewu kapena kuwoloka pakati kuti ateteze chitetezo cha magalimoto ndi okwera.

Malamulo a pamsewu m'dziko lathu ali ndi zofunikira zitatu zazikulu pakukhazikitsa zotchingira zoteteza kugundana:

(1) Mzati kapena chotetezera cha chotetezera cha ngozi chiyenera kukwaniritsa zofunikira za khalidwe. Ngati kukula kwake sikukwaniritsa zofunikira, makulidwe a galvanized wosanjikiza sikokwanira, ndipo mtundu wake si wofanana, n'zotheka kwambiri kuyambitsa ngozi za pamsewu.

(2) Chotchingira choletsa kugundana chiyenera kuikidwa ndi mzere wapakati wa msewu ngati muyezo. Ngati mbali yakunja ya msewu wa nthaka ikugwiritsidwa ntchito ngati chizindikiro cha kukhazikika, izi zidzakhudza kulondola kwa kukhazikika kwa mzati (chifukwa mzati wa nthaka sungakhale wofanana m'lifupi panthawi yomanga). Zotsatira zake, kukhazikika kwa mzati ndi njira sizikugwirizana, zomwe zimakhudza chitetezo cha magalimoto.

(3) Kukhazikitsa mizati ya chotchingira kugundana kuyenera kukwaniritsa zofunikira za khalidwe. Malo okhazikitsa mizati ayenera kukhala ogwirizana ndi kapangidwe kake ndi malo okwerera, ndipo ayenera kugwirizanitsidwa ndi malo oyendetsera msewu. Pamene njira yokumba ikugwiritsidwa ntchito kuphimba mizati, malo osungiramo mizati ayenera kupakidwa m'zigawo ndi zipangizo zabwino (kukhuthala kwa gawo lililonse sikuyenera kupitirira 10cm), ndipo mlingo wokakamiza wa malo osungiramo mizati suyenera kukhala wocheperapo kuposa nthaka yoyandikana nayo yosasokonezedwa. Mzati ukayikidwa, gwiritsani ntchito theodolite kuti muyese ndikukonza kuti mzerewo ukhale wowongoka komanso wosalala. Ngati malo osungiramo mizati sangatsimikizidwe kuti ndi owongoka komanso osalala, izi zidzakhudza chitetezo cha magalimoto pamsewu.

Ngati kuyika chotchinga cha ngozi kungakhale kosangalatsa m'maso, kungathandize kuti kuyendetsa bwino kukhale kosavuta komanso kupatsa madalaivala chitsogozo chabwino cha maso, motero kuchepetsa ngozi ndi kutayika komwe kumachitika chifukwa cha ngozi.
