1. Umgangatho weemfumba ezenziwe kwangaphambili, iintonga zeengqumba kunye nezinye iimveliso ezivela kwi-Shandong Expressway guardrail ukuya kwindawo yokwakha kufuneka zitshekishwe kwaye zamkelwe ngokungqongqo kunye nemigangatho yokwamkelwa (jonga idatha yeemfumba ezenziwe ngaphambili, izatifikethi zasefektri, iirekhodi zokuhlola umgangatho wesiseko, njl.).

Uluhlu oluvumelekileyo lweentanda kumzimba wemfumba: ubunzulu bokuvuza bungaphantsi kwe-5mm, ubude bokuvuza ngalunye abukho ngaphezu kwe-100mm, kwaye ukuqokelelwa okungekho ngaphezu kwe-5% yobude bemfumba kufuneka kulungiswe;ubunzulu bokuvuza bungaphantsi kwe-10mm, ubude bokuvuza ngakunye abukho ngaphezu kwe-300mm, kwaye abukho buninzi ubude bemfumba.Ukuqokelelwa kwe-10% yobude, okanye ukuvuza kobude be-lap akudluli i-100mm, kwaye ukuqhekeka kweemfumba akuvumelekanga ukuba kulungiswe.ipleyiti yokugqiba

2. Indlela yokusingatha imfumba kufuneka ibekwe kwindawo echongiweyo.

3. Indawo yokwakha kufuneka ihlolwe ngokungqongqo phambi kokuba iphinde ihlolwe.
Emva kweemfumba zesiseko zendalo, umhlaba ojikeleze iimfumba uya kunyanzeliswa, kwaye ukuba umgama phakathi kweemfumba ungaphantsi koluhlu oluthile, iimfumba ziya kunciphisa okanye zidibanise iimfumba ezikufutshane.Le ndlela inokuphelisa ukufuduswa komhlaba ogqithisiweyo wemfumba kunye nomhlaba okhutshiweyo obangelwa ngumhlaba okhutshiweyo ukuya kwinqanaba elithile, kodwa ukufuduka kwemfumba ephakathi akunakunqotshwa, kwaye kunokusetyenziswa ukusuka kumbindi ukuya kwiziphelo ezine.Indlela yokufaka imijikelo emibini (ngezantsi yindlela yokufaka inqwaba kunye nenani leemfumba ekwakhiweni kweqela lemfumba).Le ndlela isebenzisa umtsi wengqumba enye kwaye ibeka iimfumba ezininzi ezisecaleni kumjikelo wesibini kangangoko kunokwenzeka.Iyakwazi ukuphelisa uninzi lweemfumba zangaphakathi zokufuduka kunye nokunciphisa umphumo wokucudisa umhlaba weemfumba.Ukungalungi kukuba kwandisa ukufuduka kwe-cyclic yomqhubi wemfumba, enokuthi ibe ngenxa yokunqongophala kokuqhekeka kwemfumba ngexesha elifanelekileyo, kwaye umqhubi we-pile akakwazi ukuhamba njengoko kucwangcisiwe, ngoko ukunciphisa ukusebenza kakuhle.ukuya kulwandiso.Ngoko ke, ukukhethwa kolandelelwano lokwakha, iyunithi yokulawula kunye neyunithi yokwakha kufuneka iqwalasele ngokubanzi izinto ezininzi ezifana nesiza, uhlobo lweemfumba, uhlobo kunye nenkqubela phambili yeprojekthi, njalo njalo.

Kwi-Shandong wave guardrail abavelisi, kufuneka iveliswe ngokuhambelana nomgca wejometri

I-Wave beam guardrails ayenzelwanga ukunciphisa ukwenzeka kweengozi ezincinci.Indlela yokunqanda ukungqubana kwe-guardrail kukufunxa amandla okungqubana kwesithuthi, i-elastic-plastic deformation yomzimba wesithuthi, i-friction kunye nokufuduswa komzimba wesithuthi ngepleyiti yokugada, ukuze kukhuselwe ukhuseleko lwabahlali.I-wave guardrail yahluke kakhulu kwezinye iimpawu zokhuseleko, kukukhusela umonakalo (ukuguqulwa) kwebhodi kunye nesithuthi ngokwawo, ukukhusela umonakalo omkhulu.Misela iibhodi zokugada ukuphepha ukungqubana nezinye izinto eziyingozi, kwaye iintsimbi zokugada kufuneka zithathwe njengempahla eyingozi.Okokuthi, ukuba, phantsi kweemeko ezifanayo, ubunzima bengozi yesithuthi esingqubuzana nento ethile enobungozi buphantsi kuneso sithuthi, i-guardrail ayikwazi ukusetyenziselwa ukukhusela into eyingozi.Umzekelo, kwindlela ethe tyaba, ephantsi kwe-cocoon, ubunzima besithuthi esinqumla kwingozi ye-embankment buncinci kunobo bokungqubana kwemoto kunye ne-guardrail, nokuba kukho izithuthi ezininzi kwingozi kule nxalenye, indlela. ukukhuselwa kwe-guardrail, kunye nezinye iindlela zokhuseleko azikwazi ukusetyenziswa, Umzekelo, i-geometry yendlela iphuculwe, izibonelelo zesikhokelo sombono, iimpawu zokunciphisa isantya zibekwe, kunye nokusebenza okuchasene ne-skid kumphezulu wendlela kuphuculwe.

Okwangoku, iipali ezininzi zokuthintela zisebenzisa i-zinc steel guardrails, ezisetyenziswa kakhulu kuhola wendlela kunye noohola bendlela.Iinrayi zokukhusela eziphehlisiweyo zithatha i-69% yentsimbi egutyungelwe phezulu.Ngenxa yokumelana nokugqwesa okulungileyo kunye neempawu zokuhombisa zamaphepha e-galvanized, xa kuthelekiswa namanye amaphepha e-galvanized, ixabiso layo liphantsi, kwaye lisetyenziswe ngokubanzi kwishishini lokwakha.
