Hydraulic tamping roadbed widening construction method for construction-limited road section
The invention discloses a hydraulic tamping roadbed widening construction method for a construction-limited road section, which comprises the following steps: S1, foundation cleaning and leveling: cleaning the slope surface of an existing roadbed and a widening roadbed base, and leveling the cleaned slope surface of the existing roadbed and the widening roadbed base, the width of the existing roadbed slope and the width of the widened roadbed base are not less than the width of the road roller; s2, a retaining wall is poured, specifically, the retaining wall is poured on the outer side edge of the roadbed; s3, grating laying, wherein grating laying treatment is conducted on the arranged roadbed; s4, a broken stone hardcore, a medium-coarse sand layer clamped with an anti-seepage geomembrane, a galvanized metal net, a light soil layer and a medium-coarse sand layer clamped with the anti-seepage geomembrane are sequentially laid, and foundation bed filler is filled; when each layer is laid, compaction treatment needs to be carried out; and S5, detecting: detecting the quality of the obtained roadbed. According to the invention, the prepared roadbed is better in quality and higher in safety.
本发明公开了一种施工受限路段液压夯实路基帮宽施工方法，包括以下步骤：S1：清基整平：对现有路基坡面以及帮宽路基基底进行清理，并对清理后的现有路基坡面以及帮宽路基基底进行整平，且需要保证现有路基坡面以及帮宽路基基底的宽度不小于压路机的宽度；S2：浇筑挡土墙：对路基的外侧边部浇筑挡土墙；S3：铺格栅：对整理后的路基进行铺格栅处理；S4：依次铺设碎石垫层、夹防渗土工膜的中粗砂层、镀锌金属网、轻质土层、防渗土工膜的中粗砂层、填筑基床填料；在铺设各层时，需要进行压实处理；S5：检测：对得到的路基进行质量检测。本发明，制备的路基质量更好，安全性更高。
