Zofunikira pamagwiridwe achitetezo othamanga kwambiri oletsa kugunda

Zida zoteteza kugundana kothamanga kwambiri zimafunikira mphamvu zambiri zakuthupi, ndipo chithandizo chapamwamba cha anti-collision guardrails chimafunikira anti-corrosion ndi anti-kukalamba. Popeza kuti zoteteza nthawi zambiri zimagwiritsidwa ntchito panja, zimalimbananso kwambiri ndi kutentha kwambiri komanso kutsika. Liwiro lakugundana kwagalimoto limatanthawuza kuthamanga kwenikweni kwa galimoto yoyesera yomwe imayesedwa mkati mwa 6 metres isanafike malo enieni omwe agundana panthawi yoyeserera.
Kutengera ndi mtundu wa mapewa amsewu, mapanelo oteteza misewu yayikulu okhala ndi malata ayenera kukhala ndi mawonekedwe osiyanasiyana. Mwachitsanzo, pamene mtengo wamalata umayikidwa pakhoma losungirako ndi khoma la mapewa, mtundu wa Gr-A-2C ungagwiritsidwe ntchito.
Zofunikira pakugwirira ntchito kwachitetezo chapamsewu waukulu:
(1) Maonekedwe okongola. Mapanelo oteteza misewu yayikulu akuyenera kulumikizidwa ndi malo ozungulira msewuwo, ndipo mazenera achitetezo amatha kukongoletsedwa ndi kubiriwira ndi njira zina.
(2) Kuteteza mwamphamvu. Izi zikutanthauza kuti mawonekedwe a boardrail board ayenera kukhala ndi gawo lina la kukana kukanikiza. Sizidzaphwanyidwa mosavuta ndi magalimoto. Misewu yakutawuni imakhala ndi kuchuluka kwa magalimoto ndipo ngozi zimachitika. Kuwonongeka kwachuma kumakhalanso kwakukulu, ndipo n'kosavuta kuchititsa kuti magalimoto asokonezeke, kotero kuti chitetezo champhamvu chokwanira chikhoza kugwira ntchito inayake yotetezera, makamaka pazigawo zapamsewu zomwe zimakhala ndi magalimoto ambiri olemetsa, monga mabala apakati olekanitsa lamba omwe ali ndi mphamvu zotsutsana ndi kugunda. Kugunda kwachiwiri kunachitika ndi galimoto yomwe ikubwera.
(3) Luso lotsogolera bwino. Izi zikutanthauza kuti galimotoyo itagundana ndi Guardrail, imatha kutumizidwa kunja popanda kubwereranso kwambiri ndikuyambitsa ngozi yachiwiri ndi galimoto yomwe ili mbali imodzi.
(4) Chuma chabwino komanso kusunga malo. Ngakhale kuti tikukwaniritsa zotsutsana ndi kugundana komanso kuwongolera magwiridwe antchito achitetezo, tiyeneranso kuyesetsa kuti tichepetse kuchuluka kwa zida zachitetezo zomwe zimagwiritsidwa ntchito kuwonetsetsa kuti chuma chikuyenda bwino. Chifukwa chake, zotchingira zokhala ndi phazi laling'ono ziyenera kugwiritsidwa ntchito momwe zingathere kuti zisunge malo ndikuchepetsa mtengo wa polojekiti.
