1. Hunhu hwemirwi yakagadzirwa, mirwi yemirwi uye zvimwe zvigadzirwa kubva kuShandong Expressway guardrail kuenda kunzvimbo yekuvaka zvinofanirwa kutariswa uye kugamuchirwa zvakanyatsoenderana nezvinodiwa zvekugamuchirwa (tarisa iyo data yemapiru akagadzirwa, zvitupa zvefekitari, mirwi nheyo yemhando yekuongorora zvinyorwa, etc.).

Rutivi runobvumirwa rwekutsemuka mumutumbi wemurwi: kudzika kwekudonha kuri pasi pe5mm, kureba kwega kwega kusingapfuuri 100mm, uye kuunganidza kusingapfuuri 5% yehurefu hwemurwi kunofanirwa kugadziriswa;kudzika kwekudonha kuri kushoma kupfuura 10mm, kureba kwega kwega kudonha hakupfuuri 300mm, uye hakuna mirwi yakawanda yakareba.Iko kuunganidzwa kwe10% yehurefu, kana kureba kwemakumbo kudonha hakupfuuri 100mm, uye mirwi yakatsemuka haibvumidzwe kugadzirisa.ndege yekupedzisira

2. Nzira yekubata yemurwi inofanira kuiswa panzvimbo yakatarwa.

3. Nzvimbo yekuvaka inofanira kunyatsoongororwa isati yaongororwa zvakare.
Mushure memirwi yenheyo yechisikigo, ivhu rakatenderedza mirwi richaomeswa, uye kana kureba pakati pemirwi kuri kushoma pane imwe mhando, mirwi inobvisa kana kuyangarara mirwi iri pedyo.Iyi nzira inogona kubvisa kubviswa kwevhu remurwi uye ivhu rakaputika rinokonzerwa nevhu rakaputika kune imwe nzvimbo, asi kubviswa kwepakati pepakati hakugoni kukundwa, uye inogona kushandiswa kubva pakati kusvika kumativi mana.Nzira mbiri-kutenderera yekuputira (pazasi pane nzira yekuputira uye huwandu hwemirwi mukuvakwa kweboka remirwi).Iyi nzira inoshandisa kusvetuka kwemurwi mumwe chete uye inoisa mirwi yakawanda yepadivi muchikamu chechipiri sezvinobvira.Inogona kubvisa mirwi yakawanda yemukati yekutamisa uye kuderedza ivhu-kusvina mhedzisiro yemapile.Izvo zvisingabatsiri ndezvekuti zvinowedzera cyclic kusimuka kwemutyairi wemurwi, izvo zvingave zvichikonzerwa nekushaikwa kwekuputsika kwemurwi panguva, uye mutyairi wemurwi haagone kufamba sezvakarongwa, nekudaro kuderedza kushanda zvakanaka.kusvika pakureba.Nokudaro, kusarudzwa kwekutevedzana kwekuvaka, chikwata chekutarisa uye chikwata chekuvaka chinofanira kunyatsotarisa zvinhu zvakawanda zvakadai senzvimbo, rudzi rwemirwi, chimiro uye kufambira mberi kweprojekti, nezvimwe zvakadaro.

MuShandong wave guardrail vagadziri, inofanirwa kugadzirwa zvinoenderana nejometri mutsara

Wave beam guardrails haana kuitirwa kudzikisa kuitika kwetsaona diki.Iyo guardrail anti-collision mechanism ndeyekutora kudhumhana kwemotokari, iyo elastic-plastiki deformation yemuviri wemotokari, kupokana uye kutamiswa kwemuviri wemotokari kuburikidza neguardrail plate, kuitira kuchengetedza kuchengetedzwa kwevari mukati.Iyo wave guardrail yakasiyana zvakanyanya kubva kune mamwe maficha ekuchengetedza, ndeye kuchengetedza kukuvara (deformation) yebhodhi uye mota pachayo, kudzivirira zvakanyanya kukuvadza.Misa mabhodhi ekuchengeta kudzivirira kudhumhana nezvimwe zvinhu zvine njodzi, uye njanji dzinofanira kutorwa sezvinhu zvine ngozi.Kureva kuti, kana, pasi pemamiriro akafanana, kuomarara kwetsaona yemotokari inodhumhana nechimwe chinhu chine ngozi yakaderera pane iyo yemotokari, njanji haigoni kushandiswa kudzivirira chinhu chine ngozi.Semuenzaniso, padivi pemugwagwa wakafuratira, wakaderera-chikoko, kuomarara kwemotokari kuyambuka tsaona yemugumbo kudiki pane iyo yekudhumhana pakati pemotokari nerairi, kunyangwe paine mota zhinji mutsaona muchikamu chino, mugwagwa. kuchengetedzwa kweguardrail, uye mamwe matanho ekuchengetedza haagone kushandiswa, Semuyenzaniso, geometry yemugwagwa inovandudzwa, nzvimbo yekutungamira yekuona, zviratidzo zvekumhanya zvinoiswa, uye iyo anti-skid performance yemugwagwa inovandudzwa.

Parizvino, mapango mazhinji anodzivirira anoshandisa zinc simbi yekurinda, iyo inoshandiswa zvakanyanya mumigwagwa mikuru nemigwagwa mikuru.Galvanized guardrails inotora 69% yesimbi yakazara pamusoro-yakagadzirwa.Nekuda kweiyo yakanaka corrosion kuramba uye yekushongedza zvivakwa zvema galvanized sheet, zvichienzaniswa nemamwe ma galvanized sheets, mutengo wayo wakaderera, uye wakashandiswa zvakanyanya muindasitiri yekuvaka.
