1. Ikhwalithi yezinqwaba ezenziwe ngaphambili, izinduku zenqwaba neminye imikhiqizo evela eShandong Expressway guardrail eya endaweni yokwakha kufanele ihlolwe futhi yamukelwe ngokuvumelana nezindinganiso zokwamukela (hlola idatha yezinqwaba ezenziwe ngaphambili, izitifiketi zefekthri, amarekhodi okuhlola ikhwalithi yesisekelo senqwaba, njll.).

Ibanga elivumelekile lemifantu emzimbeni wenqwaba: ukujula kokuvuza kungaphansi kuka-5mm, ubude bokuvuza ngakunye abukho ngaphezu kuka-100mm, futhi ukunqwabelana okungengaphezu kuka-5% wobude benqwaba kufanele kulungiswe;ukujula kokuvuza kungaphansi kuka-10mm, ubude bokuvuza ngakunye abukho ngaphezu kuka-300mm, futhi abukho obude benqwaba.Ukuqoqwa kwe-10% yobude, noma ukuvuza kobude be-lap akudluli i-100mm, futhi imifantu yenqwaba ayivunyelwe ukulungiswa.indiza yepuleti lokugcina

2. Indlela yokusingatha inqwaba kufanele ibekwe endaweni ebekiwe.

3. Indawo yokwakha kufanele ihlolwe ngokuqinile ngaphambi kokuhlolwa kabusha.
Ngemuva kwenqwaba yesisekelo semvelo, inhlabathi ezungeze izinqwaba izocindezelwa, futhi uma ibanga phakathi kwezinqwaba lingaphansi kobubanzi obuthile, izinqwaba zizosusa noma zintante izinqwaba eziseduze.Le ndlela ingakwazi ukuqeda ukukhishwa kwenhlabathi ekhishwe inqwaba kanye nenhlabathi ekhishwe ngenxa yenhlabathi ekhishwe ngezinga elithile, kodwa ukufuduka kwenqwaba ephakathi akukwazi ukunqotshwa, futhi kungasetshenziswa kusukela phakathi kuya emikhawulweni emine.Indlela yemijikelezo emibili yokunqwabelanisa (ngezansi umzila wokunqwabelanisa kanye nenani lezinqwaba ekwakhiweni kweqoqo lenqwaba).Le ndlela isebenzisa ukugxuma kwenqwaba eyodwa futhi ibeka izinqwaba eziningi eziseceleni emjikelezweni wesibili ngangokunokwenzeka.Ingakwazi ukuqeda iningi lezinqwaba zokufuduka kwangaphakathi futhi inciphise umphumela wokucindezela inhlabathi wezinqwaba.Okubi ukuthi kwandisa ukuhamba kwe-cyclic komshayeli wenqwaba, okungenzeka kube ngenxa yokuntuleka kokuphuka kwenqwaba ngesikhathi, futhi umshayeli wenqwaba akakwazi ukuhamba njengoba kuhleliwe, ngaleyo ndlela anciphise ukusebenza kahle komsebenzi.ekunwebeni.Ngakho-ke, ukukhethwa kokulandelana kokwakhiwa, iyunithi yokuqondisa kanye neyunithi yokwakha kufanele kucutshungulwe ngokuphelele izici eziningi ezifana nesizinda, uhlobo lwenqwaba, ubunjalo nenqubekelaphambili yephrojekthi, nokunye.

Kubakhiqizi be-wave guardrail be-Shandong, kufanele ikhiqizwe ngokuya ngomugqa wejometri

I-Wave beam guardrails akuhloselwe ukunciphisa ukwenzeka kwezingozi ezincane.I-guardrail anti-collision mechanism ukumunca umfutho wokushayisana kwemoto, ukuwohloka kwe-elastic-plastic yomzimba wemoto, ukungqubuzana nokugudluzwa komzimba wemoto ngepuleti le- guardrail, ukuze kuvikelwe ukuphepha kwabagibeli.I-wave guardrail ihluke kakhulu kwezinye izici zokuphepha, iwukuvikela umonakalo (deformation) webhodi kanye nemoto ngokwayo, ukuvimbela umonakalo omkhulu kakhulu.Misa amabhodi e- guardrail ukuze ugweme ukungqubuzana nezinye izinto eziyingozi, futhi izinsimbi zokuqapha kufanele zibhekwe njengezimpahla eziyingozi.Okusho ukuthi, uma, ngaphansi kwezimo ezifanayo, ubunzima bengozi yemoto eshayisana nento ethile eyingozi buphansi kunaleyo yemoto, umzila wokuqapha awukwazi ukusetshenziselwa ukuvikela into eyingozi.Isibonelo, emgwaqeni oyisicaba, ophansi, ubucayi bemoto ewela engozini yomgwaqo bungaphansi kobokushayisana kwemoto ne- guardrail, ngisho noma kunezimoto eziningi engozini kule ngxenye, umgwaqo. ukuvikelwa kwe-guardrail, nezinye izindlela zokuphepha azikwazi ukusetshenziswa, Isibonelo, i-geometry yomgwaqo iyathuthukiswa, izindawo zokuqondisa umbono, izimpawu zomkhawulo wejubane ziyasethwa, nokusebenza okulwa nokushushuluza kwendawo yomgwaqo kuyathuthukiswa.

Njengamanje, izigxobo eziningi zokuvimbela zisebenzisa insimbi yokuqapha i-zinc, esetshenziswa kakhulu emigwaqweni emikhulu nasemigwaqweni emikhulu.Izinsimbi zokuvikela ezenziwe ngamagalani zenza u-69% wesamba sensimbi efakwe emanzini.Ngenxa yokumelana nokugqwala okuhle kanye nezakhiwo zokuhlobisa zeshidi likathayela, uma kuqhathaniswa namanye amashidi ama-galvanized, izindleko zawo ziphansi, futhi isetshenziswe kabanzi embonini yokwakha.
