Full-bonding prestress anti-floating anchor rod and construction method thereof
The full-bonding prestress anti-floating anchor rod comprises a twisted steel bar, the twisted steel bar comprises a prestress section and a full-length bonding section, the prestress section is located in a raft plate layer, the full-length bonding section is located in an anchor rod hole of a concrete layer, a spiral stirrup is fixedly installed on the side wall of the prestress section, and an anchorage device is installed at the end of the prestress section; the prestress section is sleeved with a sleeve, and the spiral stirrup is located in the sleeve. The full-length bonding section comprises a plurality of positioning frames fixedly installed on the twisted steel, the positioning frames are arranged along the twisted steel, the anchor rod holes are filled with cement paste, and the cement paste and the twisted steel are fixedly connected with the side wall after the cement paste is solidified. The anchor rod has high durability and corrosion resistance, the anti-pulling bearing capacity of the anchor rod is high, the waterproof performance of the joint is good, and the anchor rod is suitable for application and popularization.
本发明提出了一种全粘结预应力抗浮锚杆包括螺纹钢筋，螺纹钢筋包括预应力段与全长粘接段，预应力段位于筏板层内，全长粘接段位于混凝土层的锚杆孔内，预应力段侧壁固定安装有螺旋箍筋，预应力段端部安装有锚具，预应力段套装有套管，螺旋箍筋位于套管内部；全长粘接段包括固定安装在螺纹钢筋上的定位架，定位架沿螺纹钢筋设置有多个，锚杆孔内灌装有水泥浆，所述水泥浆凝固后与螺纹钢筋固定连接侧壁。本锚杆具有较强的耐久性和抗腐蚀性，且本锚杆抗拔承载力强、节点防水性较好，适于推广应用。
