Okokuqala, xa ukhetha umenzi, kufuneka uhlolisise ngononophelo amandla omenzi, nokuba ngumenzi okanye umntu ophakathi, nokuba ngaba ishishini elisemthethweni okanye i-workshop encinci.Emva kokumisela amandla omenzi, kungcono ukujonga kwiintlobo zabo ezithile zeendlela zokugada kunye neendlela zokukhetha, ukusetyenziswa kwabathengi, kunye nolwazi lwempendulo, ukuze ube nokuqonda okungcono komenzi.

Okwesibini, emva kokumisela amandla omenzi kunye nolwazi lwempendulo evela kubathengi, kuyimfuneko ukuqhubela phambili ukuqonda izinto kunye nobugcisa bendlela yokugada.Iimfuno zembonakalo nazo ziphezulu kakhulu.Ngexesha lokuhlolwa, kuya kufuneka ujonge ukumelana ne-corrosion, ukuxhathisa kwe-asidi kunye ne-alkali, kunye nokumelana nobushushu obuphezulu be-guardrail.Kungcono ukujonga ingxelo yokuhlola umgangatho kunye nembeko eyenziwe ngumenzi kwisebe lokuhlola umgangatho.Izatifikethi, njl., ukwenzela ukuba ukwazi ngokuchanekileyo amandla omenzi.

Okwesithathu, umgaqo wokugada uhola wendlela udla ngokusetyenziswa ixesha elide emva kokuba ufakiwe kwaye usetyenziswa.Ngoko ke, kuyimfuneko ukuqonda imiba efanelekileyo emva kokuthengisa, njengale: ixesha lewaranti, kuthatha ixesha elingakanani ukuba abasebenzi emva kokuthengisa balungise umonakalo kwi-guardrail yendlela, indlela yokuvumelana ngembuyekezo kunye notshintshiselwano, kunye nokunye. kwi.
