装配式公路钢桥机械化架设及其工程应用

装配式公路钢桥是我国国防交通应急和抢险救灾的重要应用工具,在我国一直是人工建设,虽然钢桥实用性强,但由于其本身主要构件大且重,数量多,因此在紧急道路施工中耗时费力。目前我国很多研究所都在就如何利用机械取代人工进行架桥这一课题进行研究,经过大量的实验,国内研发了装配式公路钢桥成套机械化架设及集装化吊运机具,这种新型架桥不仅减少了人力耗费,同时也大大减少了紧急时段的架桥时间。文章就这种新型架桥吊运机具进行分析。

Assembled highway steel bridge is the important application tool in the field of national defense transportation emergency and disaster relief, has been the artificial construction in our country, although the steel bridge has strong practicability, because of its main components are big and heavy, large quantity, so time - consuming in emergency road construction. At present many institute in our country are researching on how to use machinery to replace manual, through a large number of experiments, has developed complete sets of mechanized construction of the assembled highway steel bridge and unitized lifting machines, this new type of method not only reduces the manpower cost, but also greatly reduces the bridging time of emergency period.
