公路桥梁施工技术分析

近年来,随着我国经济的迅猛发展,国民生活水平的不断提高,国家越来越重视交通业的发展,人们也越来越重视交通的便利性与舒适性。如今,各种机动车等被经常使用,让公路桥梁不堪重负,出现了众多问题。因此,为了延长公路桥梁的使用寿命,保证人们的交通安全,需要重视公路桥梁的施工,在公路桥梁的整个施工过程中,把控好可能出现危险的各个环节及要点,尤其是对施工技术的严格要求。施工技术包括很多,如对于公路桥梁加固方面,当前比较先进的技术为预应力加固技术;使用非常多的现浇箱梁施工技术;钻孔灌注桩施工技术;桩基加固技术;养护桥梁的技术;高墩施工的关键技术,文章还介绍了公路桥梁施工中伸缩缝的施工技术类型等等,对于这些技术,研究人员在实践中仔细推敲,并不断创新,希望此文对我国公路桥梁施工技术的发展有一定的借鉴和指导意义。

In recent years,with the rapid development of China's economy and the continuous improvement of national living standards,China pays more and more attention to the development of the transportation industry,and people pay more and more attention to the convenience and comfort of transportation.Nowadays,private cars and motor vehicles are often used,which makes roads and bridges unbearable,resulting in many problems.Therefore,in order to prolong the service life of highway bridges and ensure people's traffic safety,we should pay attention to the construction of highway bridges and control the dangerous links and key points in the whole construction process of highway bridges,especially the strict requirements for construction technology.There are many construction techniques,such as prestress reinforcement technology for highway bridge reinforcement,cast-in-place box girder construction technology,bored cast-in-place pile construction technology,pile foundation reinforcement technology and bridge maintenance technology.The key technology of high pier construction,the paper also introduces the construction technology types of expansion joints in highway bridge construction,and so on.For these technologies,researchers carefully deliberate in practice and innovate constantly.It is hoped that this paper has a certain reference and guiding significance for the development of highway bridge construction technology in China.
