公路改扩建工程技术策略

在公路改扩建的工程施工中,要增强对高等级公路的综合管理以及当前技术控制的各个需要,采取切实可行的公路改扩建方式,最大限度地防止出现不均匀沉降以及路面成型之后在拼接位置出现一定的纵向裂缝等现象,全面提升改扩建之后工程的整体质量。文章主要围绕当前改扩建的主要形式进行分析,并结合具体的工程实例,从路基加宽处理、路基拼接加宽防损处理、处治技术等方面进行探讨,更好地实现公路改扩建工程技术的全面应用。

In the construction of highway reconstruction and expansion projects, it is necessary to strengthen the comprehensive management of high-grade highways and meet the various needs of eurrent technical control, adopt feasible road reconstruction and expansion methods, to maximize the prevention of uneven settlement and the formation of pavement after the splicing position of a certain longitudinal cracks and other phenomena, and comprehensively improve the overall quality- of the project after the reconstruc- tion and expansion. This paper mainly analyzes the main fomls of reconstruction and extension at present, and discusses from the as- pects of roadbed widening treatment, roadbed splicing widening and damage prevention treatment, and treatment technology, and con- crete engineering examples, etc. Therefore, it is better to realize the comprehensive application of highway- reconstruction and exten- sion engineering technology.
