Okokuqala, ngenxa yeempawu zemveliso ye-high-speed guardrail, iyimveliso yokucutshungulwa kwangaphambili kwentsimbi.Ke ngoko, eyona nto iphambili echaphazela ixabiso lakhe yintsimbi.Njengoko sonke sisazi, ixabiso strip steel liguquguquka kakhulu, ngokusisiseko ukutshintsha yonke imihla, kunye guardrail kuba inqanaba langoku lophuhliso lwemarike ifikelele kwixesha leenzuzo ezincinane kodwa imbuyekezo ngokukhawuleza, nto leyo ekhokelela ngqo guardrails.Ixabiso lentsimbi alikwazanga ukuthwala ukufikeleleka kweenguqu zexabiso lentsimbi, kwaye liyakwazi ukuguquguquka kuphela ngokuguquguquka kwexabiso lentsimbi ye-strip.

Xa imarike iphakama, ilandelwa ngokungahambiyo ngokunyuka kwensimbi, kwaye xa ixabiso lemarike liyancipha, ukuze kugcinwe ukusebenza okuqhelekileyo kwefektri, kuya kunciphisa ixabiso ngenkuthalo.Yiyo loo nto ixabiso leentsimbi zokugada liguquguquka rhoqo.Ke ngoko, kuya kubakho abathengi abaninzi abanexesha elide lokwakha kunye nemfuno enkulu ngokulinda-kwaye-bona kwaye baqonde ukuba baya kubeka inani elikhulu lee-odolo xa ixabiso le-guardrail liphantsi, bahlawule imali ethile yediphozithi. umenzi we-guardrail, usayine isivumelwano, kwaye utshixe ixabiso, ngoko akukho mfuneko yakukhathazeka malunga nokuhlawula ngenxa yokunyuka kwamaxabiso emarike.Imali eninzi inokonga imali eninzi.
