Foundation pit supporting hollow anchor rod capable of improving uplift bearing capacity and construction method thereof
The invention discloses a foundation pit supporting hollow anchor rod capable of improving uplift bearing capacity and a construction method thereof, and relates to the technical field of building foundation pit supporting, the foundation pit supporting hollow anchor rod comprises an anchor rod body, the anchor rod body is of a hollow structure, multiple rows of through holes are evenly formed in the anchor rod body in the axial direction, and an annular notch groove is formed in the inner wall of the anchor rod body; the annular notch grooves are formed between two adjacent rows of through holes; a center shaft is arranged in the anchor rod body and is of a cylindrical structure, and a plurality of anchoring structures are arranged between the center shaft and the anchor rod body. According to the foundation pit supporting hollow anchor rod capable of improving the uplift bearing capacity and the construction method of the foundation pit supporting hollow anchor rod capable of improving the uplift bearing capacity, the uplift bearing capacity of the anchor rod body can be greatly improved on the premise that the rod diameter and the rod length of the anchor rod body are constant; the anti-pulling bearing capacity of the anchor rod supporting system is increased by setting the occlusal force of the soil-squeezing columns and the soil body, and the stability of the anchor rod supporting system can be greatly improved due to the existence of the soil-squeezing columns.
本发明公开了一种可提高抗拔承载力的基坑支护空心锚杆及其施工方法，涉及建筑基坑支护技术领域，包括锚杆本体，锚杆本体设置为中空结构，锚杆本体沿轴向均匀开设有多排通孔，锚杆本体的内壁上设置有环形刻槽，环形刻槽设置在相邻的两排通孔之间；锚杆本体内部设置有中轴，中轴设置为圆柱状结构，中轴和锚杆本体之间设置有多组锚固结构。本发明采用上述结构的一种可提高抗拔承载力的基坑支护空心锚杆及其施工方法，可在锚杆本体的杆径和杆长恒定的前提下大幅增加锚杆本体的抗拔承载力；通过设置挤土柱与土体的咬合力来增加其抗拔承载力，且挤土柱的存在可以大幅提高锚杆支护系统的稳定性。
