Kodi kugunda kwa liwiro ndi chiyani?Kodi zofunika zake ndi zotani?

Mabomba othamanga, omwe amadziwikanso kuti mabampu othamanga, ndi malo omwe amaikidwa m'misewu yayikulu kuti magalimoto aziyenda pang'onopang'ono.Mawonekedwe ake nthawi zambiri amakhala ngati amavula, komanso ngati mfundo;zakuthupi makamaka mphira, komanso zitsulo;zambiri zachikasu ndi zakuda kukopa chidwi chowoneka, kotero kuti msewu pang'ono arched kukwaniritsa cholinga cha deceleration galimoto.Lamba wochepetsera mphira amapangidwa ndi zinthu za mphira, mawonekedwe ake ndi otsetsereka, mtunduwo nthawi zambiri umakhala wachikasu ndi wakuda, ndipo umakhazikika pamsewu ndi zomangira zowonjezera, zomwe ndi malo otetezeka agalimoto.Dzina la sayansi limatchedwa rubber deceleration ridge, lomwe limapangidwa molingana ndi mfundo ya ngodya ya tayala ndi mphira wapadera pansi pamene galimoto ikuyenda, ndipo imapangidwa ndi mphira wapadera.Ndi mtundu watsopano wa chipangizo chachitetezo chokhazikika pamagalimoto chomwe chimayikidwa pakhomo la misewu yayikulu, mabizinesi amakampani ndi migodi, masukulu, malo okhala, ndi zina zambiri kuti achepetse kuthamanga kwa magalimoto ndi magalimoto osayendetsa.

Zofunikira pazambiri za bampu liwilo la rabara (mitunda):

1. Mphepete mwa mphira yochepetsera mphira iyenera kupangidwa mophatikizana, ndipo kunja kwake kumakhala ndi mikwingwirima kuti iwonjezere kumamatira.
2. Chigawo chilichonse cha deceleration ridge chiyenera kukhala ndi retro-reflective zinthu zosavuta kuzizindikira usiku, moyang'anizana ndi njira yoyendetsera galimoto.
3. Pasakhale ma pores pamwamba, pasakhale zokopa zoonekeratu, kusowa kwa zinthu, mtundu ukhale wofanana, ndipo pasakhale kung'anima.
4. Dzina la gawo lopangirako liyenera kupanikizidwa pamwamba pa mphira wochepetsera mphira.
5. Ngati italumikizidwa pansi ndi ma bolts, mabowo a bolt ayenera kukhala mabowo otsukidwa.
6. Chigawo chilichonse cha mtunda wa deceleration chiyenera kulumikizidwa m'njira yodalirika.

Gawo laling'ono la chigawo chochepetsera m'lifupi ndi kutalika kwake liyenera kukhala lofanana ndi trapezoidal kapena arc.M'lifupi gawo liyenera kukhala mkati mwa (300mm±5mm)~ (400mm±5mm), ndipo kutalika kwake kuyenera kukhala pakati pa (25mm±2mm)-(70mm±2mm).Chiŵerengero cha m'lifupi ndi kukula sikuyenera kupitirira 0.7.

Kuthamanga koyenera kwa rabara-pulasitiki kuyenera kuonetsetsa kuti galimotoyo sidzatha kuyendetsa galimoto ikadutsa, ndipo zigawo zofunika zachitetezo sizidzathyoledwa ndi zochitika zina zoopsa, ndipo ziyenera kukhala ndi kuyendetsa kwakukulu ndi chitetezo chapangidwe.
