M'zaka zaposachedwapa, ndi kuwonjezeka kwa umwini wa galimoto ndi kusowa kwa malo oimika magalimoto, chitetezo cha magalasi apadera chakhala chodetsa nkhaŵa kwa eni magalimoto ambiri. Pothana ndi nkhaniyi, njira yatsopano yothetsera vutoli - bollard yonyamulika - ikukula pang'onopang'ono kumadera monga UK ndi Europe.
Mtundu uwu wa bollard wosunthika wonyamulika siwongowoneka bwino komanso wamphamvu pantchito. Zopangidwa ndi zida zamphamvu kwambiri, zimatha kupewa kuba komanso kugwira ntchito mosaloledwa m'malo oimika magalimoto. Kupyolera mu ntchito yosavuta yamanja, eni galimoto amatha kukweza kapena kutsitsa bollard mosavuta, motero amawongolera mwayi wopita ku garaja.
Poyerekeza ndi ma bolladi okhazikika, ma bolladi osunthika osunthika amapereka kusinthasintha kwakukulu komanso kosavuta. Zitha kukhazikitsidwa ndi kuthetsedwa nthawi iliyonse, kulikonse, ndipo zimatha kusunthidwa ndikusinthidwa ngati pakufunika. Izi zikutanthauza kuti eni galimoto angagwiritse ntchito bollard yomweyo pazochitika ndi malo osiyanasiyana popanda kufunika kowonjezera ndalama zowonjezera ndi kukonza.
Kuphatikiza apo, ma bollards osunthika osunthika alinso ndi mwayi woteteza mphamvu komanso kuteteza chilengedwe. Popeza amagwira ntchito pamanja, palibe magetsi kapena magwero ena amphamvu omwe amafunikira. Izi sizimangochepetsa kugwiritsa ntchito mphamvu komanso zimachepetsanso ndalama zogwirira ntchito komanso kuwononga chilengedwe.
Pamene kuzindikira kwa anthu za chitetezo cha magalasi achinsinsi kukuchulukirachulukira, ma bollards onyamulika akhazikitsidwa kukhala chisankho chachikulu m'tsogolomu. Sikuti amangopatsa eni magalimoto mwayi woimikapo magalimoto osavuta komanso otetezeka komanso amapereka njira zatsopano zoyendetsera magalimoto m'tawuni.
Chondetifunseningati muli ndi mafunso okhudza malonda athu.
