Construction method for widening old road in hilly area
The invention provides a construction method for widening an old road in a hilly area, which belongs to the technical field of road construction and comprises the following steps of: 1, preparing construction, including field measurement, material test and technical preparation; step 2, obstacle clearing and meter clearing; 3, earthwork construction is conducted, specifically, full-width segmented construction is adopted for a rerouting section roadbed, half-width segmented construction is adopted for an original road transformation section, so that smooth road surface traffic is guaranteed, and construction of an unfavorable geological section, construction of a roadbed excavation section, construction of a roadbed filling section and roadbed protection and drainage are included; the method further comprises concrete drainage structure construction and bridge and culvert construction. 4, performing pavement engineering, including concrete drainage structure construction and circular pipe culvert construction; and fifthly, auxiliary engineering construction is conducted. The method is used for widening and transforming old roads in specific areas, and the construction quality and efficiency are improved.
本发明提供了丘陵地区旧路拓宽的施工方法，属于道路施工技术领域，包括以下步骤，第一步，准备施工，包括现场测量，材料测试和技术准备；第二步，清障，清表；第三步，土方施工，改线地段路基采用全幅分段施工，原路改造地段采用半幅分段施工，以保证路面交通顺畅，包括不良地质地段的施工、路基挖方段的施工、路基填方段的施工和路基防护及排水；还包括混凝土排水结构施工和桥涵施工；第四步，路面工程，包括混凝土排水结构施工、圆管涵施工；第五步，附属工程施工。本发明针对特定地区旧路拓宽改造，提升施工质量和效率。
