同新建公路和桥梁相比,对公路旧桥进行扩宽加固及连接施工拥有自身独特的特点。近年来,我国在积极进行交通运输业建设的过程中,全国各地多处开展了公路旧桥扩宽加固及连接施工。鉴于此,本文首先对公路旧桥扩宽加固及连接进行了简要概述,并从工程实际出发,对公路旧桥扩宽加固及连接技术的应用展开了分析,希望对我国交通运输业的发展起到促进作用。 Compared with the newly built roads and bridges, the old bridge on the highway to expand the reinforcement and connection construction has its own unique characteristics. In recent years, in the process of actively carrying out the construction of the transportation and transportation industry in our country, the expansion and reinforcement of the old bridges on the roads and the construction of connections have been carried out in various places throughout the country. In view of this, this paper first briefly expands the reinforcement and connection of the old road bridges, and from the engineering practice, analyzes the application of widening and reinforcement of the old bridges and the connection technology, hoping to play an important role in the development of China’s transportation industry To promote the role.
