公路路基拱形骨架防护工程施工技术

Construction Technology of Highway Subgrade Arch Skeleton Protection Engineering

路基是公路建设中的核心部分,决定着最终建设质量,与公路整体承载力及稳定性密切相关,并且是行车舒适、安全的重要影响因素。现阶段,在开展公路工程建设时,一般通过现浇混凝土拱形骨架实现路基防护工程施工,可以借助该结构的优势增强整个公路的承载力,尽量防止行车事故发生。基于此,本文结合相应工程案例,探讨了公路路基拱形骨架防护工程施工技术,包括放样施工技术、基槽开挖施工技术、模板安装技术、拱形骨架砌筑施工技术、混凝土浇筑与压顶施工技术、混凝土养护施工技术等。

Subgrade is the core part of highway construction,which determines the final construction quality,and is closely related to the overall bearing capacity and stability of the highway,and is an important factor affecting driving comfort and safety.At the present stage,in the development of highway engineering construction,generally through the cast-in-place arch concrete skeleton realization of subgrade protection engineering construction,can use the advantages of the structure to enhance the bearing capacity of the whole highway,as far as possible to prevent driving accidents.Based on this,this paper discusses the engineering construction technology,including lofting construction technology,construction technology of foundation groove excavation construction technology,formwork installation technology,arch skeleton masonry construction technology,concrete pouring and roof pressing construction technology,concrete maintenance construction technology,etc.
