Construction method for retaining wall with single anchor and anchor supporting plate tensioned for multiple times
The construction method comprises the implementation steps that S1, according to the filling height, soil pressure or residual sliding force is calculated, the number of layers of anchor supporting plates needed in the vertical direction, the number of supporting plates in the horizontal direction and the length of anchor cables are determined, and the number of construction filling layers is determined according to the number of layers of the anchor supporting plates; s2, a side retaining wall is constructed, and an anchoring channel is reserved; s3, at least one layer of geogrid is laid within the range of 500 mm below the filling height where the supporting plate is located, and a uniform settlement layer is formed; s4, when the first calculated filling height is reached, the anchor cable unit corresponding to the supporting plate at the farthest end of the lowest layer is tensioned and locked; and S3, the step S3 is repeated, and the anchor cable units corresponding to the last nth supporting plate of the first layer are sequentially tensioned and locked at the nth calculated filling height. According to the method, the anchoring units are sequentially and progressively arranged in the vertical direction, so that the retaining wall is scientific and reasonable in overall stress, running water beat tensioning construction is adopted, and construction is easy, convenient and feasible.
本申请公开了一种单锚多次张拉锚托板挡墙及施工方法，其实施步骤S1：根据填方高度，计算土压力或剩余下滑力，确定竖直方向上所需锚托板层数、水平向上各托板数量及锚索长度，并根据锚托板层数确定施工填筑层数；步骤S2：施工面侧挡墙，并注意预留锚固通道；步骤S3：在托板所在填筑高度下方500mm范围内上铺设至少1层土工格栅，形成均匀沉降层；步骤S4：达到第一计算填筑高度，张拉最下一层最远端托板对应的锚索单元并锁定；重复S3步骤，在到达第n计算填筑高度处，依次张拉第1层倒数第n块托板对应的锚索单元并锁定。该方法在竖直方向依次递减设置锚固单元，使得该挡墙整体受力科学合理，采用流水节拍张拉施工，施工上简便可行。
