Zotchinga zotchinga ndi mipanda yomwe imayikidwa pakati kapena mbali zonse ziwiri za msewu kuti magalimoto asathamangire pamsewu kapena kuwoloka pakati kuti ateteze chitetezo cha magalimoto ndi okwera.
Lamulo lapamsewu m'dziko lathu lili ndi zofunikira zitatu pakukhazikitsa ma anti-collision guardrail:
(1) Chigawo kapena cholondera chachitetezo cha ngozi chikuyenera kukwaniritsa zofunikira. Ngati kukula kwake sikukugwirizana ndi zofunikira, makulidwe a galvanized layer sikokwanira, ndipo mtunduwo suli yunifolomu, ndiye kuti ukhoza kuyambitsa ngozi zapamsewu.
(2) Njira yoteteza kugundana iyenera kudulidwa ndi msewu wapakati ngati benchmark. Ngati kunja kwa nthaka msewu phewa ntchito monga kutchulidwa kwa stakeout, izo zidzakhudza kulondola kwa mzati mayikidwe (chifukwa nthaka roadbed sangakhale yunifolomu m'lifupi pomanga). Chotsatira chake, kuyanjanitsa kwa mzere ndi njira ya njirayo sikugwirizana, zomwe zimakhudza chitetezo cha pamsewu.
(3) Kuyika ndime yachitetezo cha ngozi kudzakwaniritsa zofunikira. Kuyika kwa mzatiyo kuyenera kukhala kogwirizana ndi zojambula zojambula ndi malo okwera, ndipo ziyenera kugwirizanitsidwa ndi kayendetsedwe ka msewu. Njira yofukula ikagwiritsidwa ntchito kukwirira mizati, zotsalirazo zimapangidwira m'magawo okhala ndi zinthu zabwino (makulidwe amtundu uliwonse sayenera kupitirira 10cm), ndipo kuphatikizika kwa kubwezeredwa sikungakhale kocheperako kuposa komwe kumalumikizidwa mozungulira. nthaka. Pambuyo poika ndime, gwiritsani ntchito theodolite kuti muyese ndikuwongolera kuti muwonetsetse kuti mzerewo ndi wowongoka komanso wosalala. Ngati kuyanjanitsa sikungatsimikizidwe kukhala kowongoka komanso kosalala, mosakayikira kudzakhudza chitetezo chamsewu.
Ngati kukhazikitsidwa kwa chotchinga changozi kungakhale kosangalatsa m'maso, kumathandizira kuyendetsa bwino chitonthozo ndikupatsa madalaivala chitsogozo chowoneka bwino, potero kuchepetsa kuchitika kwa ngozi ndi zotayika zomwe zimachitika chifukwa cha ngozi.
