Anchor rod foundation construction method
The invention belongs to the technical field of building foundation construction, and discloses an anchor rod foundation construction method which comprises the following steps: S1, determining the central positions of all anchor holes according to the center of a bearing platform; s2, drilling holes in the center positions of the anchor holes; s3, blocking and protecting the drilled and formed anchor hole; s4, according to a preset drilling sequence, the step S2 and the step S3 are repeated, and all anchor holes in a single bearing platform are constructed; s5, a foundation pit of the bearing platform is excavated; and S6, plugging of the anchor holes is removed, anchor rods are inserted into the anchor holes, and grouting is conducted. During construction, all the anchor holes in the bearing platform are drilled firstly, then the foundation pit of the bearing platform is excavated, deep foundation pit operation during anchor hole construction is avoided, the construction difficulty is effectively reduced, and the safety coefficient is high. Before the foundation pit is excavated, the anchor hole formed after drilling is blocked and protected, chippings are prevented from falling into the anchor hole when the foundation pit is excavated, and the later cleaning workload is reduced. All the anchor rod foundations are sequentially constructed through the construction method, and the construction period can be shortened.
本发明属于建筑基础施工技术领域，公开一种锚杆基础施工方法，包括以下步骤：S1、根据承台的中心确定所有锚孔的中心位置；S2、在锚孔的中心位置钻孔；S3、封堵保护钻设成型后的锚孔；S4、按照预设钻孔顺序，重复步骤S2和步骤S3，施工完成单个承台中所有锚孔；S5、开挖承台的基坑；S6、去除锚孔的封堵，在锚孔内插设锚杆并注浆。施工时，先钻设出该承台中所有的锚孔，再开挖承台的基坑，避免了施工锚孔时深基坑作业，有效降低施工难度，且安全系数高。在开挖基坑前，封堵保护钻设成型后的锚孔，避免开挖基坑时的碎屑掉入锚孔内，减少后期清理工作量。采用本施工方法施工依次施工所有锚杆基础，能够缩短施工周期。
