道路桥梁预应力加固技术

Prestress reinforcement technology for road and bridge

道路桥梁预应力加固技术的进一步使用,使道路桥梁自身的质量在一定程度上得到了不断的提高。预应力技术一般应用在相对比较大的工程或施工面积广的中小型桥梁施工中。修建时间比较久的钢桥,不仅要对其进行定期维修,同时还要做好养护工作,对预应力施工过程中的技术进行有效的运用,只有这样才能够延长桥梁使用期限,使其经济效益不断增加。

The further use of road and bridge prestress reinforcement technology makes the improvement in quality of road and bridge to a certain extent. Prestress technology is generally used in relatively large projects or construction area of small and medium-sized bridge construction. The steel bridge with relatively long history should have regular maintenance,and make effective use of prestress technology in conservation work,only in this way can extend the use period of bridge and increase its economic benefits.
