Construction method for quickly dredging river-along subgrade during water damage
The invention relates to the technical field of highway subgrade engineering, and particularly relates to a construction method for quickly dredging a river-along subgrade during water damage. The construction method comprises the following steps: S1, prefabricating a reinforced gabion on site; S2, stacking the reinforced gabion at a slope toe to form a slope toe retaining wall; S3, filling stonematerials layer by layer between the slope toe retaining wall and a highway and compacting layer by layer to form a stone-filled embankment; and S4, mounting a slope protection net for protecting thestone-filled embankment on the slope surface of the stone-filled embankment. The construction method provided by the invention is convenient in overall construction, economical and applicable, and lowin safety risk; and taking a 50-meter water-damaged subgrade section as an example, the construction period is 5-7 days, and compared with the prior art, the construction period is greatly shortened.The river-along subgrade constructed by the construction method provided by the invention can form a whole, so that the flood erosion resistance of the river-along subgrade is improved, and the disaster resistance of the river-along subgrade is further enhanced; and even if the river-along subgrade meets super-standard flood, serious subgrade damage such as road breakage is avoided, and long-termsmoothness of the river-along highway is guaranteed.
本发明涉及公路路基工程技术领域，特别涉及一种沿河路基水毁快速抢通施工方法，包括以下步骤：S1、现场预制钢筋石笼；S2、将钢筋石笼堆叠在坡脚处以形成坡脚挡墙；S3、在坡脚挡墙与公路之间逐层填筑石料并分层压实以形成填石路堤；S4、在填石路堤的坡面安装对其进行保护的护坡防护网。本发明的施工方法，整体施工便捷，经济适用，安全风险低，以50米长的水毁路基段为例，施工周期为5‑7天，与现有技术相比，大大缩短了施工周期。采用本发明的施工方法施工的沿河路基可形成一个整体，提高了其抵抗洪水冲刷淘蚀的能力，进而增强了沿河路基的抗灾能力，即使遇到超标准洪水，也不会出现断道等严重的路基毁坏，保证了沿河公路长期畅通。
