Post-embedding method of cylindrical anchorage device structure for reducing excavation volume of foundation pit
The invention relates to the technical field of foundation pit support, and discloses a post-embedding method of a cylindrical anchorage device structure for reducing the excavation volume of a foundation pit, which comprises the following steps: S1, binding a reinforcement cage; s2, a reinforcement cage is placed in the pile hole, and pile body concrete is poured; s3, after the foundation pit is excavated to the inclined support installation position, anchor holes are drilled, anchor cables are placed, and grouting is conducted on the anchor holes; s4, the inclined support is installed on the reinforcement cage; and S5, after the grouting strength of the inclined support installation area meets the requirement, the anchorage device is installed in the inclined support, the anchor cable is tensioned and locked through the anchorage device, and finally the anchor is sealed. According to the technical scheme, the excavation volume of the foundation pit can be reduced, the construction cost is reduced, meanwhile, the construction period can be shortened, and the high-altitude operation risk caused by fat groove filling operation is avoided.
本发明涉及基坑围护技术领域，公开了一种用于减少基坑开挖量的筒式锚具结构的后置嵌入方法，包括以下步骤：S1：绑扎钢筋笼；S2：将钢筋笼放入桩孔内，并浇筑桩体混凝土；S3：待基坑开挖到斜托安装位置后，钻锚孔，放锚索，锚孔注浆；S4：将斜托安装在钢筋笼上；S5：待斜托安装区域灌浆强度满足要求后，将锚具安装在斜托内，张拉锚索，并用锚具锁定锚索，最后封锚。本发明的技术方案能够减少基坑的开挖量，降低施工成本，同时，也能够缩短施工工期，避免了肥槽填充作业带来的高空作业风险。
