Expanded-head anti-floating anchoring device and construction method
The invention provides an expanded-head anti-floating anchoring device and a construction method, and relates to the technical field of anti-floating anchor rod construction.The expanded-head anti-floating anchoring device mainly comprises an anchor rod, an anti-corrosion sleeve and a foundation sole.The anti-corrosion sleeve is installed at the bottom end of the anchor rod and connected with a rubber pipe to solve the problems that an existing anti-floating anchor rod is poor in corrosion resistance and pulling bearing capacity; the rubber pipe is expanded after being filled with grout to form a protruding structure surrounding the anti-corrosion sleeve, the durability of the anti-floating anchoring device is improved, the rubber pipe is of a multi-section bent structure, the structure distributed in an inclined state can enable the anti-floating anchoring device to be stressed stably, the shear resistance of the anti-floating anchoring device is improved, the stress of the grout injected into the position of the expansion head is coordinated, and the uplift bearing capacity of the anti-floating anchoring device is improved.
本发明提供一种扩大头抗浮锚固装置及施工方法，涉及抗浮锚杆施工技术领域，主要包括锚杆、防腐套管和基础底板，针对目前抗浮锚杆耐腐蚀性差及抗拔承载力差的问题，在锚杆底端安装防腐套管并连接橡胶管，橡胶管充入浆液后膨胀从而形成围绕防腐套管的凸起结构，提高抗浮锚固装置的耐久性，橡胶管为多段弯折结构，倾斜状态分布的结构能够使其受力稳定，提高其抗剪性能，协同扩大头位置注入的浆液受力，提升抗浮锚固装置的抗拔承载力。
