Guardrails. Cholinga ndi mitundu ya guardrails

An yofunika chigawo gawo misewu ndi guardrails. Ntchito yawo yaikulu - zoti wa njira yodutsamo kuyenda zoyendera, komanso kuchepetsa ngozi zapamsewu ndi kutsekeka kwa galimoto akugwetsa mu dzenje. Iwo ayamba ntchito protections sangokhala kokha pa maulendo wautali, komanso m'madera a m'tawuni mmene mpanda chitetezo.

The mitundu ikuluikulu ya guardrails

Kuonetsetsa 2 magulu waukulu zopinga:

1. Zomangamanga a mtundu chotchinga (zamwano, kumathandiza kuchepetsa, ndi zina zotero. D.), amene ntchito popewa magalimoto ku congresses panjira, milatho overpasses, komanso kupewa ngozi ndiponso zotsatira pa zomangamanga ndi mzere. Chotchinga mipanda, kungakhale zitsulo, simenti ndi pulasitiki.
2. Kulengedwa chipongwe mtundu - zitsulo mauna, anafuna ulesi kuchoka pa njira gawo la nyama, komanso kukonza kayendedwe ka anthu oyenda pansi.

zitsulo kusamala

Chifukwa ubwino wake, mtundu wa mpanda ndi otchuka. Ndi dongosolo deform pamene kugunda. Mbiri zitsulo chili pa zitsulo payekha kapena poyimitsa matabwa. Pamene kugunda gawo la galimoto amatenga pa absorber mphamvu oyenerera pakati pa pachithandara ndi ndani. Choncho, udindo waukulu mpanda - kuchepetsa ngozi pamsewu muchepetse ngozi.

machenjerero oterewa mosavuta anaika ndipo ankaiphwasula. Ntchito zopinga zitsulo msewu, osati m'misewu ikuluikulu komanso pa pomanga, ndi kuchinga pansi mabacteria.

mipanda izi zopangidwa mogwirizana ndi mfundo zenizeni za GOST. Posankha ziwembu kuwonjezera cholinga zawo zothandiza, onetsetsani kuti kuganizira nyengo ndi zivomerezi. Mogwirizana ndi zimenezi zachokera pa zipilala.

mipanda konkire

zomangamanga Izi si deformable anapanga konkire kapena analimbitsa simenti. Mu mawonekedwe a kumathandiza kuchepetsa ntchito kuchinga:

• mu msinkhu ndi masentimita 35, yomwe ndi yosalala anamaliza m'mphepete ndi kutumikira msewu monga kukongoletsa kampira;
• yomanga msinkhu wa masentimita 35 mpaka 50 ndi m'mphepete motsetsereka kuti akhoza kusunga galimoto pa njira ya.

Kuwonjezera iwo, pali embankments - kutalika kwake masentimita oposa 50. Maonekedwe a mamangidwe akufanana khoma mosalekeza umene umawalekanitsa panjira ku njira oyenda ndiponso kupewa galimoto ku kusiya msewu. Kunja padziko zopinga awa zambiri anapambutsa ndi anamaliza m'mphepete chapamwamba.

madzi odzazidwa midadada

Tsopano ndi zachilendo mipanda chotchinga, zopangidwa pulasitiki. machenjerero oterewa ndi ubwino ndithu poyerekeza ndi simenti kapena zitsulo. Komanso ndi wosavuta kunyamula kwabasi, m'makola mwawo izi kupereka chitetezo chachikulu ngati ngozi ya galimoto.

Ambiri ndi madzi odzazidwa msewu midadada zopangidwa ofiira ndi oyera mitundu pulasitiki. Pamene kuwadzaza ndi madzi kupyolera dzenje ndi pakamwapo pamwamba pa mawonekedwe alipo nyumba khola ndithu lomwe kutumikira kufika otaya magalimoto, komanso pofuna kupewa ngozi ngati yolimba chipongwe roadwork. Pansi pa mpanda ali mabowo kwa ngalande. pulasitiki ntchito kuti zopinga madzi odzazidwa, kukana zosiyana kusintha mwadzidzidzi kutentha, chingathe kupirira kutentha kwa -40 ⁰S zokha pansi cheza dzuwa, N'zosavuta kwa anthu oyera ndi sikutanthauza kupenta.

Kuthekera kwa dongosolo la midadada pa njira ina iliyonse zina amalola mbali iliyonse kutsekeramo msewu, kuphatikizapo amazipotokola osiyanasiyana ankasinthana, komanso mabowo ndi kunkhondo. Pa zopinga akhoza kuzilemba zina kulemba chimawala. Monga kukwapula zithunzi chosaiwalika, pulasitiki chitetezo mipanda kuthandiza pofuna kupewa ngozi.

zina kuchinga

Chitetezo pa kumanga kwenikweni chofunika ntchito mipanda wapadera chitetezo zopangidwa onse pulasitiki ndi zinthu zina.

Njira omanga malo amaonedwa pulasitiki yowala masikito, limene kuoneka bwino bwino mu nyengo iliyonse. Iwo yodziwika ndi mphamvu yapamwamba, lightness ndi kukana kuwonongeka, zomwe zimachititsa iwo nthawi yayitali.

Mauna mtundu zitsulo chipongwe chagwiritsidwa ndi cholinga streamlining kayendedwe ka anthu oyenda pansi ndi kuteteza maonekedwe a nyama pa njira ya.

M'malo a gululi nthawi zina amagwiritsidwa ntchito tepi zoteteza ndi alternating mitundu ofiira ndi oyera. M'misewu m'goli, nthaka, maenje, kapena vuto lililonse chingalepheretse zofewa phirilo zooneka guardrails, kusonyeza garlands kapena foni mpanda ndi chizindikiro.
