Munzira huru,tambo ine minzwamambure edziviriro anowanzo kudzivirira vanhu nemhuka kuti vasayambuka mugwagwa mukuru pamadiro, kuitira kuti vasakanganise kutyaira uye kuderedza tsaona, pamwe nekudzivirira zvinobudirira kutorwa kwemigwagwa zvisiri pamutemo nedzimwe nyaya dzekuchengetedza migwagwa.Kune marudzi akawanda emambure ekudzivirira etambo, simbi inowanzo shandiswa, mambure akarukwa, waya ine minzwa uye kazhinji yegirini gracilaria.Metal akarukwa mambure akaiswa munzvimbo dzine vanhu vakawanda, waya ine minzwa inoshandiswa munzvimbo dzine vanhu vashoma nemhuka, uye chimiro cheheji newaya ine minzwa inoshandiswa munzvimbo dzekubhadharisa uye munzvimbo dzemasevhisi.Mumakore maviri apfuura, tichifunga nezvekunaka kwedambudziko, munharaunda yePearl River Delta yemamwe migwagwa mikuru ine michero yepurasitiki nzvimbo welding network (yaiwanzoti guardrail network), iyi tambo ine minzwa yekudzivirira network inotaridzika, yakasimba, iyo yakazara. mhedzisiro yakanaka, asi zvinodiwa zvekuvaka zvakakwirira, zvinodhura.Zvikamu zvakazara hazvifanirwe kushandiswa, mukati meguta, nzvimbo dzinoyevedza kana zvakasimba zvinodiwa zvezvikamu zvakanaka zvinogona kushandiswa.
Yayo chaiyo dhizaini dhizaini nheyo ndeye:
1, tambo ine minzwaDziviriro net yepakati mutsetse munzira mukati memuganhu wenyika 20 kusvika 50 cm yakaiswa.
2. Kana paine zvidziviso zvechisikigo zvakaita semigero, madziva nemadziva padivi pemugwagwa, mambure ane minzwa ekudzivirira haafanirwe kuiswa panzvimbo isingaite zvekutyira vanhu nezvipfuyo zviri kupinda nekupinda mumugwagwa zvisiri pamutemo. land.
3, ine minzwa tambo yekudzivirira mambure muzambuko, mugero, inofanira kuva yakananga zambuko musoro koni mutsetse (kana kuguma rusvingo) nzira yakakomberedzwa, haafaniri kusiya vanhu, zvipfuwo anogona kuboora kupinda pakakoromoka.
4, tambo ine minzwa fenzi uye culvert mharadzano, senge mugero wakatetepa, tambo ine minzwa netambo fenzi inogona kuyambuka mugero yakafara, tambo ine minzwa.tambo ine minzwa ruzhowayakaoma kuyambuka, inogona kutora zambuko, nzira yekugadzirisa nzira.
5, kana ichinge yaganhurwa nenzvimbo, tambo yakakomberedzwa tambo yekudzivirira mambure isati yasvika uye mushure menguva inoenderera, tora nzvimbo sekupera kwetambo yakakomberedzwa mambure ekudzivirira, uye kubata nekupera kwekuvharirwa.
6, yakakomberedzwa tambo dziviriro network dhizaini inofanirwa kuenderana nemugwagwa muganho wenzvimbo inodiwa kugadziridzwa, flat chikamu level set, slope chikamu mutserendende kana nhanho seti.
