Zofunikira pakuyika zolepheretsa kuwonongeka

Zotchinga zotchinga ndi mipanda yoyikidwa 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 zofunika zitatu zazikuluzikulu zokhazikitsa ma anti-collision guardrail:

(1) Chigawo kapena cholondera chachitetezo cha ngozi chikuyenera kukwaniritsa zofunikira.Ngati kukula kwake sikugwirizana 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 ndime ndi njira ya njirayo sikugwirizana, zomwe zimakhudza chitetezo chamsewu.

(3) Kuyika ndime yachitetezo cha ngozi kudzakwaniritsa zofunikira.Kuyika kwa mzatiyo kuyenera kutsatiridwa molingana ndi chojambula chojambula ndi malo okwera, ndipo kuyenera kugwirizanitsidwa ndi kayendetsedwe ka msewu.Njira yofukula ikagwiritsidwa ntchito kukwirira mizati, zotsalirazo zimapangidwira m'magawo okhala ndi zida zabwino ( makulidwe a gawo lililonse sayenera kupitirira 10cm), ndipo kuchuluka kwa compaction kwa backfill sikuyenera kukhala kochepa kuposa komwe kumalumikizidwa mozungulira. nthaka.Pambuyo poyika ndimeyi, gwiritsani ntchito theodolite kuti muyese ndikuwongolera kuti mzerewo ukhale wowongoka komanso wosalala.Ngati kuyanjanitsa sikungatsimikizidwe kukhala kowongoka komanso kosalala, mosakayikira kudzakhudza chitetezo chamsewu.

Ngati kukhazikitsidwa kwa chotchinga changozi kumatha kukhala kosangalatsa m'maso, kumathandizira kuyendetsa bwino chitonthozo ndikupatsa madalaivala chitsogozo chowoneka bwino, potero kuchepetsa kuchitika kwa ngozi ndi kuwonongeka komwe kumachitika chifukwa cha ngozi.
