Tunnel anchor of single-hole double-anchor system
The invention provides a tunnel anchor of a single-hole double-anchor system, and belongs to the technical field of bridge engineering. Only one tunnel anchor is arranged on each side of a suspension bridge, two main cables are arranged in the same tunnel, and anchoring systems are installed in the same anchor body. The tunnel is in a large-section horn shape and is in the structural form of a variable cross section which is big in bottom and small in mouth. The two main cables are installed on an anchoring plug through a vice cable saddle. The double anchoring systems are installed inside the anchoring plug. The design and construction of the tunnel anchor are not limited by the distance between the left and right main cables, and the problem that because the distance between the main cables is small, the tunnel anchor can not be adopted for the narrow suspension bridge is solved. Meanwhile, the research shows that because a middle rock wall between common tunnel anchors is omitted, the structural safety, stability and durability of the tunnel anchor are obviously improved, and compared with the common tunnel anchor, the manufacturing cost of the tunnel anchor is lowered by one third.
