Prestressed grid anchorage is a new and reliable engineering technology that has a broad application in slope and landslide treatment. This technology uses pressure-dispersion tensile reinforcing bars, in which the wires extending from anchor holes are combined with the relative wires from all directions in the middle position and then tensioned together. Under this condition, external anchor piers are not necessary, and it can be tensioned repeatedly. Both the grid and the node show a plum-type layout. The construction of this composite slope anchor structure is simple, thereby overcoming the disadvantages of cast-reinforced concrete frame beams, such as easy cracking, easy deformation, and complex construction, and achieving a safe anchoring effect.
