Guardrails. Injongo neendidi guardrails

An candelo yinxalenye ebalulekileyo zeendlela ezi guardrails. Owona msebenzi wabo - ukonyulwa isikhokelo ukuhamba kwezithuthi, kwakunye nokunciphisa iingozi ezindleleni kunye nezithintelo isithuthi uwisa zombini emhadini. ngokuya zisetyenziswa ezi ukhuselo kungekuphela kwiindlela-elide umgama, kodwa kwiindawo ezisezidolophini enjengothango kukhuseleko.

Eyona eziphambili ze guardrails

Yaba amaqela 2 eziphambili zezithintelo:

1. Ezakhiwe yohlobo isithintelo (izinyeliso, esikuthintela, njalo njalo. D.), Nguwuphi ezisetyenziswa ukuthintela izithuthi evela ngeenkongolo endleleni, iibhulorho, iibhulurho, kwaye kananjalo ukuze bawaphephe kunye neempembelelo phezu izakhiwo izinto emgceni. iingcingo isithintelo, unokuba zesinyithi, ikhonkrithi kunye zeplastiki.
2. Design uhlobo wakunyelisa - umnatha metal, ekujongwe ukuba zithene phuma endleleni inxalenye izilwanyana, kwakunye ukuba balungelelanise ukuhamba ngeenyawo.

unogada steel

Ngenxa izinto zayo, olu hlobo thango kakhulu ethandwa. It is a ukugqabhuza isakhiwo xa hit. Iprofayile metal busisigxina kwi intsimbi ngamnye okanye nezinye izinto ngamaplanga. Xa inxalenye yokungqubana le imoto kuthatha phezu amandla absorber elahliweyo phakathi nesakhelo kunye iprofayili. Ngoko ke, indima ephambili ucingo - ukuncitshiswa iingozi ezindleleni kunye nokunciphisa impembelelo yeengozi.

Uyilo ezinjalo kungaba lula efakiweyo ngabunye. imiqobo endleleni metal elisetyenzisiwe, hayi kuphela koohola kodwa kwiziza zokwakha, nangenxa Ukubiyelwa ngeenyawo imimandla.

Ezi iingcingo kwenziwa ngokungqinelana neemfuno ezithile GOST. Xa ukhetha yoyilo ukongeza ngokwenjongo zazo zepraktikhali, qiniseka ukuba bakuthathele ingqalelo iimeko zemozulu seismic. Ngokuhambelana kunye nale meko lujolise phezu kweentsika.

Ucingo eziphathekayo

Oku ezakhiwe non-deformable eyenziwe ngekhonkrithi ikhonkrithi okanye lwesamente. Xa uhlobo esikuthintela isicelo ukubiya:

• ubude ne-35 cm, leyo abe egudileyo, edge elirhangqiweyo kwaye abe bokuhombisa zabahamba halo;
• ukuphakama ukwakhiwa cm 35 ukuya 50 kunye ngohlangothi engumnqantsa ukuze ukugcina isithuthi kwindlela yezithuthi.

Ukongezelela kubo, Kusekho manzi - ukuphakama kwayo ngaphezu kwe-50 cm. Inkangeleko ngayo le kuyilo kufana udonga eqhubekayo esahlula endleleni emendweni ngeenyawo kwaye uthintele nokusetyenziswa isithuthi ekushiyeni ecaleni. indawo ngaphandle kwale mida nabavumayo jikelele kunye ngohlangothi eliphezulu ajikelezayo.

iibhloko ezaliswe ngamanzi

Ngoku iingcingo isithintelo eziqhelekileyo, eyenziwe ngeplastiki. Uyilo ezinjalo iingenelo kakhulu xa kuthelekiswa ikhonkrithi okanye wentsimbi. Ukongeza kulula ukuthutha kwaye ufake, ezi nemiluko zinika ukhuseleko lexikulu xa kwingozi yemoto.

Avamise kakhulu iibhloko kwindlela ngamanzi-ezaliswe ezenziwe imibala zeplastiki bomvu namhlophe. Xa ukuzigcwalisa ngamanzi ngokusebenzisa umngxuma ngesiciko phezu kwifom ezikhoyo nezakhiwo kakhulu esitalini leyo abakhonza ukuba batshintshe ukuhamba kwezithuthi, ngokunjalo ukuqinisekisa ukhuseleko njenge wakunyelisa roadwork eyomeleleyo. Emazantsi ucingo iye imigodi yamanzi. Le yeplastiki esetyenzisiweyo ukwenza izithintelo ezaliswe ngamanzi, ukumelana ezahlukileyo utshintsho ngesiquphe kwamaqondo obushushu, unako ukumelana ubushushu ukuya -40 ⁰S alutshitshi phantsi imitha yelanga, ekulula ukuzicoca yaye ayifuni ukupeyinta.

Ithuba yelungiselelo iibhloko kwi engile eyahlukileyo kwelinye kuvumela naziphi na izabelo sivale indlela, kubandakanywa ilenze ezahlukeneyo kunye amathuba, kwakunye imingxunya kunye imingxuma. On enjalo umqobo unako avalwe i iziphawuli ezongezelelweyo ekhanyayo. Njengoko bamxabela isikhonkwane ezibonwayo, iingcingo zokhuseleko zeplastiki ukunceda ukuqinisekisa ukhuseleko.

Ezinye iintlobo ukubiya

Ukhuseleko ngexesha lokwakha efunekayo ngokuyimfuneko ukusebenzisa iingcingo zokhuseleko ekhethekileyo eyenziwe zombini zeplastiki kunye nayiphi na enye into.

Eyona ndlela kakhulu ekwakheni sayithi kwesefu iplastiki eqaqambileyo, leyo ngokucacileyo ezibonakalayo na imozulu. Bona luphawulwa ngamandla aphezulu, ndandifeketha kunye nokumelana ukubola, nto leyo eyenza ukuba ixesha elide kakhulu.

Enemingxuma uhlobo metal wakunyelisa ziyasetyenziswa injongo ngokuyenza intshukumo abahambi ngeenyawo kunye nokuthintela imbonakalo izilwanyana endleleni.

Endaweni igridi ngamanye amaxesha basebenzisa tape yokhuselo kunye alternating imibala abomvu namhlophe. Kwiindlela obungalinganiyo, umhlaba, wemihadi, okanye nayiphi na imiqobo enokuthintela guardrails cone-ezimile ethambileyo, ebonisa nezidanga okanye ucingo ehambayo ilogo.
