Izithintelo zokuphahlazeka zizicingo ezifakwe embindini okanye kumacala omabini endlela ukuthintela izithuthi ekubalekeni endleleni okanye ukuwela i-median ukukhusela ukhuseleko lwezithuthi kunye nabakhweli.
Umthetho wendlela welizwe lethu uneemfuno eziphambili ezintathu zokufakelwa kweendlela zokunqanda ukungqubana:
(1) Ikholamu okanye i-guardrail ye-guardrail yengozi kufuneka ihlangabezane neemfuno zomgangatho. Ukuba ubungakanani bayo abuhambisani neemfuno, ubukhulu bomgca we-galvanized akwanele, kwaye umbala awufani, kunokwenzeka ukuba kubangele izingozi zendlela.
(2) Intsimbi yokunqanda ukungqubana iya kunqunyulwa kunye nomgca osembindini wendlela njengomlinganiselo. Ukuba ngaphandle kwegxalaba lendlela yomhlaba isetyenziswe njengesalathiso se-stakeout, iya kuchaphazela ukuchaneka kokulungelelaniswa kwekholomu (kuba i-roadbed yomhlaba ayikwazi ukufana nobubanzi ngexesha lokwakha). Ngenxa yoko, ukulungelelaniswa kwekholomu kunye nolwalathiso lwendlela alulungelelaniswa, oluchaphazela ukhuseleko lwendlela.
(3) Ufakelo lwekholamu ye-wall guardrail iya kuhlangabezana neemfuno zomgangatho. Isikhundla sokufakela ikholomu kufuneka sihambelane ngokungqongqo nomzobo woyilo kunye nendawo yokuphakamisa, kwaye kufuneka ilungelelaniswe nokulungelelaniswa kwendlela. Xa indlela yokumba isetyenziselwa ukungcwaba iikholomu, i-backfill iya kunyanzeliswa kwiileya kunye nezixhobo ezilungileyo (ubukhulu boluhlu ngalunye abuyi kudlula i-10cm), kwaye iqondo lokuxinwa kwe-backfill aliyi kuba ngaphantsi kunelo elikufutshane lingaphazanyiswa. umhlaba. Emva kokuba ikholamu ifakwe, sebenzisa i-theodolite ukulinganisa kwaye uyilungise ukuze uqinisekise ukuba umgca ulungile kwaye ulungile. Ukuba ulungelelwaniso alunakuqinisekiswa ukuba luthe tye kwaye lugudile, ngokuqinisekileyo luya kuchaphazela ukhuseleko lwezithuthi ezindleleni.
Ukuba ukufakwa kwesithintelo sokuphazamiseka kunokukholisa iliso, kuya kuphucula ngcono induduzo yokuqhuba kunye nokubonelela abaqhubi ngesikhokelo esibonakalayo esilungileyo, ngaloo ndlela kuncitshiswe ngokufanelekileyo ukwenzeka kweengozi kunye nelahleko ebangelwa ziingozi.
