Ngomklamo wayo ohlukile, uhlelo lwe-Sigma Post lunikeza ukusebenza okuqinile mayelana nokuqukatha kwemoto kanye nokumuncwa komthelela. Lesi sihloko sicubungula ekucacisweni kobuchwepheshe, amamethrikhi okusebenza, imikhuba yokufaka, kanye nentuthuko engaba khona yesikhathi esizayo yesistimu ye-Sigma Post guardrail, inikeza ukuqonda okujulile kochwepheshe bezokuphepha emgwaqeni.

2. Ukucaciswa Kwezobuchwepheshe kanye Nezimiso Zomklamo

2.1 Iphrofayela ye-Sigma Post

Uhlelo lwe-Sigma Post guardrail lubonakala ngokusetshenziswa kwalo Okuthunyelwe okumise okwe-Sigma, ehlanganisa amandla esakhiwo namandla asebenzayo okumunca amandla.

Ubukhulu: I-Sigma Posts ngokuvamile ifaka ubude obungu-610 mm nobubanzi obungu-150 mm. Umumo "we-Sigma" uklanyelwe ukukhulisa kokubili ukusekelwa kwesakhiwo nokumuncwa kwamandla ngesikhathi sokushayisana.
Material: Yenziwe ngensimbi enamandla amakhulu, Izikhala ze-Sigma zaziwa ngokuhlala kwazo nokumelana nezimo zemvelo.
- Isivuno Amandla: Ngokuvamile phakathi kuka-345 no-450 MPa.
- Amandla Okuqina Eshubile: Ngokuvamile isukela ku-483 kuya ku-620 MPa.
Ubukhulu: Okuthunyelwe ngokuvamile kunogqinsi luka-3.42 mm (igeji engu-10), okuqinisekisa ukuthi angakwazi ukubekezelela umthelela obalulekile ngaphandle kokwehluleka.
Ukuhlanzeka: Insimbi ine-hot-dip efakwe uthayela enogqinsi lwe-coating elinganiselwa ku-610 g/m² ukuze ivikele ekugqwaleni futhi inwebe impilo yesevisi.

2.2 System Izingxenye

Uhlelo lwe-Sigma Post guardrail luqukethe izinto ezimbalwa ezibalulekile ezisebenza ndawonye ukuze zinikeze ukuqukatha okusebenzayo kwemoto kanye nokuphathwa komthelela:

Posts: Okuthunyelwe okumise okwe-Sigma kuklanyelwe ukugxilisa isistimu ye-Guardrail ngokuqinile futhi amunce amandla omthelela.
- Ubukhulu: Okuthunyelwe ngokuvamile kungu-150 mm ububanzi no-610 mm ukuphakama.
Imisindo: Ivamise ukwenziwa ngamaphrofayili e-W-Beam noma e-Thrie Beam, lawa ma-rail anamathiselwe kokuthi Okuthunyelwe kwe-Sigma ukuze akhe umgoqo omkhulu.
Ukuvinjwa: Izikhala ezibekwe phakathi kwamaposi namareyili ukuze kugcinwe ubude obufanele besitimela nokuthuthukisa ukumuncwa kwamandla ngesikhathi sokushayisana.
Izinsimbi Zesitimela: Izigaba zikaloliwe zixhunywe kusetshenziswa amabhawodi noma ezinye izixhumi ukuze kuqinisekiswe ukuqhubeka kulo lonke uhlelo lokuvimba.
Qeda Amatheminali: Izingxenye ezikhethekile ezifakwe ekugcineni kwesistimu ye-Guardrail ukuze kwehliswe izinga ngokuphephile noma kuqondiswe kabusha izimoto.
