实现中小桥梁的结构轻型化、预制工厂化、装配机械化,从而采用工业生产方式施工是国内外桥梁的发展趋势,也是实现公路现代化急待要解决的重要课题。中小桥梁数量多,在我地区就占全部桥梁座数的98％,其中险、旧桥梁改造的任务是很大的。为了加快公路建设速度,降低造价,我们试做了一座小桥,采用了工业生产方式施工,取得了成效。现将其设计和施工情况简介如下。
To achieve the lightweight structure of small bridges, prefabricated factories, assembly mechanization, so that the use of industrial production is the development trend of bridges at home and abroad, but also an urgent need to solve the highway modernization important issue. Small number of bridges, in my area accounted for 98% of the total number of bridges, of which insurance, the task of transformation of the old bridge is great. In order to speed up the speed of highway construction and reduce the cost, we tried to build a small bridge and adopted industrial production methods to achieve success. Now the design and construction of the situation are as follows.
