Ngakhale truss utenga zitsulo zokulirapo, dongosolo ndi losavuta, amene osati ali ndi mwayi amphamvu kusinthika kwa prefabricated Bailey zitsulo mlatho, komanso amapanga kwa malire a chikhato, bwino kutalika kwa danga limodzi ndi kupulumutsa mtengo wa mlatho pier. .

Mtengo wa HBD60mtunduchitsulo chopangira chitsulo chokhazikika nthawi zambiri chimakhala ndi mizere iwiri yokhazikika yokhala ndi chord chachitatu, chomwe chimasonkhanitsidwa kuchokera kuzinthu zokhazikika monga ma trusses omaliza, zigawo zokhazikika za truss, zolumikizira, zolumikizira zolimba, zida zachitatu, zopingasa, ndodo zomangira mphepo, ndi zothandizira zowongoka. Trasi yayikulu imalumikizidwa ndi ma bolts amphamvu kwambiri. Ma truss okhazikika ndi 3.048m kutalika, ndi kutalika kwa wosanjikiza umodzi wa 2.250m ndi kutalika kwapawiri kwa 4.500m. Pali ma trusses awiri mbali imodzi, ndipo njira yonyamuliramo imatenga malo okhazikika a mlatho wa konkriti kapena chitsulo cha mlatho.

Mayendedwe ndi Kusunga kwa HBDMtundu wa 60Zitsulo Zomanga Bridges

1) Pakutsitsa, kuyendetsa, ndi kutsitsa kwazinthu panthawi yotumiza, ndikofunikira kupewa kuwononga filimu ya utoto, komanso kuwonongeka kwapang'onopang'ono ndi kusinthika kwa zigawo.

2) Njira zingapo zoyendera ziyenera kugwiritsidwa ntchito potengera gawo, ndipo mosasamala kanthu kuti ndi iti yomwe imagwiritsidwa ntchito, mayendedwe apakatikati ayenera kuchepetsedwa.

3) Potumiza zigawo, wopanga ayenera kupereka chiphaso cha khalidwe la mankhwala kwa wogwiritsa ntchito, mndandanda wa zigawo za mankhwala, ndi malangizo ogwiritsira ntchito mlatho wachitsulo.
