Power transmission tower rock negative Poisson's ratio anchor rod foundation reinforcing structure and construction method thereof
The invention discloses a power transmission tower rock negative Poisson's ratio anchor rod foundation reinforcing structure and a construction method thereof, and the reinforcing structure comprises a concrete foundation which is poured on a rock foundation and is used for bearing a power transmission tower leg; the anchor rod reinforcing group is used for anchoring the concrete foundation on the rock foundation, and the anchor rod reinforcing group comprises a plurality of NPR anchor rods; the foundation bolts are used for fixing the tower legs of the power transmission tower on the concrete foundation; the NPR anchor rod comprises a rod body and a sleeve, one end of the rod body is an anchoring end anchored in a rock foundation, a cone is arranged at the other end of the rod body, the rod body is sleeved with the sleeve, and a containing cavity used for containing the cone is formed in the sleeve. The cone extrudes the inner wall of the containing cavity so that the sleeve can expand and deform in the radial direction. According to the NPR anchor rod, most of material deformation is converted into structural deformation, namely relative displacement between the cone and the sleeve, and the phenomenon that a power transmission tower is damaged due to material failure can be effectively avoided.
本发明公开一种输电塔岩石负泊松比锚杆基础加固结构及其施工方法，该加固结构包括：混凝土基础，其浇筑在岩石地基上，且用于承载输电塔塔腿；锚杆加固群，其用于将混凝土基础锚固在岩石地基上，所述锚杆加固群包括多个NPR锚杆；地脚螺栓，其用于将输电塔塔腿固定在所述混凝土基础上；所述NPR锚杆包括杆体和套管，杆体的一端为锚接在岩石地基中的锚固端，杆体的另一端设置有锥体，所述杆体套接在套管内，所述套管内形成有用于容置所述锥体的容置腔；所述锥体挤压所述容置腔的内壁而使所述套管发生径向膨胀变形；本发明中NPR锚杆将材料变形绝大部分转化为结构变形，即锥体与套管之间的相对位移，能有效避免因材料失效导致的输电塔破坏现象。
