Dry silty-fine sand slope backfill reinforcement construction method
The invention relates to a dry silty-fine sand slope backfill reinforcement construction method which comprises the following steps: S1, according to a geological exploration report, comparing a soil sample grain composition curve of an excavation area with a vibroflotation distinguishing graph, and determining construction parameters; s2, checking whether the result meets the requirement or not according to the design specification and the slope stability safety coefficient; s3, slope reinforcement is conducted in a layered mode, and slope reinforcement of each layer comprises a layered rolling construction area and a filler-free vibroflotation construction area; the layered rolling construction area is located on the outer side of the slope, and the filler-free vibroflotation construction area is located on the inner side; the layered rolling construction of the next layer is located above the filler-free vibroflotation construction area of the previous layer; constructing and reinforcing the side slope layer by layer; in each layer of slope reinforcement, a layered rolling construction area is firstly constructed, and then a filler-free vibroflotation construction area is constructed; and finally, filler-free vibroflotation construction is conducted on the position close to the inner side of the side slope, and reinforcement of the whole side slope is completed. According to the scheme, the construction efficiency can be improved, and the reinforcing effect is guaranteed.
本发明涉及一种干燥粉细砂边坡回填加固施工方法，包括以下步骤：S1、根据地勘报告，将开挖区域土样颗粒级配曲线与可振冲性区分图进行对比，确定施工参数；S2、根据设计规范、边坡稳定性安全系数，验算结果是否满足要求；S3、分层进行边坡加固，每一层边坡加固包括：分层碾压施工区域和无填料振冲施工区域；分层碾压施工区域位于边坡外侧，无填料振冲施工区域位于内侧；后一层的分层碾压施工位于前一层无填料振冲施工区域的上方；逐层施工加固边坡；每一层边坡加固都先施工分层碾压施工区域，再施工无填料振冲施工区域；直至达到设计高度，最后对靠近边坡内侧的位置进行无填料振冲施工，完成全部边坡加固。本发明方案可以提高施工工效，保证加固效果。
