Ibhulorho yokugada ibhekisa kumgaqo wokugada ofakwe kwibhulorho.Injongo yalo kukuthintela izithuthi eziphuma ekulawuleni ukuba zingaphumi ebhulorhoni, nokuthintela izithuthi ukuba zingagqobhozi, ziwele ngaphantsi, zidlule ibhulorho, zihombise isakhiwo sebhulorho.Zininzi iindlela zokwahlulahlula iibhulorho zokugada.Ukongeza ekwahluleni ngendawo yofakelo, inokwahlulwa ngokweempawu zesakhiwo, ukusebenza okuchasene nongquzulwano, njl.njl. Ngokwendawo yofakelo, inokwahlulwa ibe yibhulorho yecala lokulinda, ibhulorho esembindini yecandelo lokulinda kunye nabahambi ngeenyawo kunye nomda we-driveway. umzila wokulindangokweempawu zesakhiwo, inokwahlulwa ibe yi-beam-column (intsimbi kunye nekhonkrithi) i-guardrail, i-concrete yekhonkrithi eqinisiweyo yocingo lokwandisa kunye ne-guardrail edibeneyo;Ngokokusebenza okuchasene nongquzulwano, inokohlulwa ibe yi-guardrail eqinileyo, i-semi-rigid guardrail kunye ne-flexible guardrail.

Ukucaciswa okusemgangathweni kunye noMsebenzi weBridge Guardrail

Ukukhethwa kwefom yebhulorho yokugada kufuneka kuqala imisele ibakala lokulwa nongquzulwano ngokwebakala lohola wendlela, ingqwalasela ebanzi yokhuseleko lwayo, ulungelelwaniso, iimpawu zento eza kukhuselwa, kunye neemeko zejometri zesayithi, kwaye ngoko ngokwesakhiwo sayo, uqoqosho. , ukwakhiwa kunye nokugcinwa.Izinto ezifana nokukhethwa kwefom yesakhiwo.Iindlela eziqhelekileyo zebhulorho yokugada yi-concrete guardrail, i-corrugated beam guardrail kunye ne-cable guardrail.

Ingaba ibhuloho yokugada iyindawo yobuhle okanye yokukhusela, emva kokuba iimoto ezininzi ziqhekeza i-guardrail kwaye zawela emlanjeni, le ngxaki nayo yafakwa ngokungathanga ngqo phantsi kwe "microscope".

Enyanisweni, iindawo zokugada kumacala omabini ebhulorho zinika ingqwalasela engakumbi kukhuseleko lwabahambi ngeenyawo, kwaye ungqameko phakathi kwendlela esecaleni kwendlela kunye nendlela emacaleni omabini ngowona “mgca wokhuselo” ubalulekileyo ukuvala itrafiki.Kwiibhulorho zasezidolophini, ii-curbs zibekwe ekudibaneni kwendlela yokuhamba kunye nendlela emacaleni omabini.Umsebenzi oyintloko walo mgca wokukhusela kukuthintela izithuthi kunye nokuthintela ukuba zingangqubani nabahamba ngeenyawo okanye zibethe ibhuloho.I-guardrail kwicala langaphandle lebhulorho isetyenziselwa ukukhusela abahambi ngeenyawo kwaye inamandla obuthathaka okumelana nokungqubana.

Ukucaciswa okusemgangathweni kunye noMsebenzi weBridge Guardrail

Kutheni le nto umba wokhuseleko lwe-guardrail ungahoywa ngokulula?Ixesha elide, abaqulunqi beebhulorho kunye nabaphathi belizwe lethu baye banikela ingqalelo ngakumbi kukhuseleko lwesakhiwo esiphambili sebhulorho kunye nokuba ibhulorho iya kudilika, ngelixa ingayihoyi indlela izakhiwo ezincedisayo ezifana ne-curbs kunye ne- guardrails ziqinisekisa ukhuseleko lwezithuthi kunye nabahamba ngeenyawo. .Mninzi indawo yokuphucula, kwaye mninzi umsebenzi wobuchule omele wenziwe.Ngokwahlukileyo koko, amazwe aseNtshona aphuhlileyo angqongqo yaye acokiseke ngakumbi.“Baluthathela ingqalelo uyilo lweentsimbi zokugada kunye neepali zokukhanya kwibhulorho kakuhle kakhulu.Umzekelo, ukuba isithuthi sibethe kwipali yokukhanya, baya kuqwalasela indlela yokuqinisekisa ukuba ipali yokukhanya ayiyi kuwa phantsi ize ibethe isithuthi emva kokubethwa.Ukuqinisekisa ukhuseleko lwabantu.

Akunakwenzeka ukuba nayiphi na ibhulorho yokugada ithintele zonke iimpembelelo zengozi."Ucingo olukhuselayo lunempembelelo yokukhusela kunye nokukhusela, kodwa nayiphi na ibhulorho yokugada ayinakuthiwa iyakwazi ukumelana neengozi phantsi kwazo zonke iimeko."Oko kukuthi, kunzima ukuchaza ukuba zingaphi iitoni zezithuthi ezibetha ibhulorho yokulinda ngesiphi isantya.Kuqinisekisiwe ukuba akusayi kubakho ngozi ekuweleni emlanjeni.Ukuba isithuthi esikhulu singqubana ne-Guardrail ngesantya esiphezulu okanye kwi-angle enkulu yokuhlaselwa (kufuphi nolwalathiso oluthe nkqo), amandla empembelelo adlula umda wekhono lokukhusela le-Guardrail, kwaye i-Guardrail ayinakuqinisekisa ukuba isithuthi asiyi kuphuma ngokukhawuleza. yebhulorho.

Ngokuqhelekileyo, iindawo zokugada kufuneka zifakwe kumacala omabini ebhulorho ngokuhambelana neekhowudi okanye imigangatho efanelekileyo.Nangona kunjalo, ukuze nayiphi na ibhulorho yokugada iqhube umsebenzi wayo, kufuneka kubekho imiqathango ehambelanayo.Ngokomzekelo, i-angle yempembelelo kufuneka ibe phakathi kwama-20 degrees.Ukuba i-angle yempembelelo inkulu kakhulu, i-guardrail iya kuba nzima ukusebenza.
