Suspension bridge tunnel type anchorage and construction method
The invention provides a suspension bridge tunnel type anchorage and a construction method, and relates to the field of bridge engineering, the suspension bridge tunnel type anchorage comprises a front anchor chamber vertically arranged on a mountain; the main cable chamber is obliquely arranged on the front side of the mountain and communicates with the front anchor chamber; the anchor hole is located under the front anchor chamber, the anchor hole is formed in the vertical direction and communicates with the front anchor chamber, and the inner diameter of the anchor hole is gradually increased from top to bottom; the anchor plug body comprises a steel member and a concrete body, the steel member is arranged on the inner bottom surface of the anchor hole, and the anchor hole above the steel member is filled with the concrete body; and the main anchor cable penetrates through the main cable chamber and is connected with the steel member. Due to the fact that the axial direction of the anchor hole is perpendicular to the horizontal plane, the anchor hole excavation workload can be greatly reduced, the construction period can be greatly shortened, and the collapse risk is reduced; the anchor plug body is in wedge-shaped fit with the inner wall of the anchor hole, the contact area is larger, the range of driving surrounding rock to participate in bearing is larger, the dead weights of the anchor plug body and the surrounding rock can be used for balancing the load of the main cable, and the bearing capacity of the tunnel type anchorage is greatly improved.
本发明提出了一种悬索桥隧道式锚碇及施工方法，涉及桥梁工程领域，包括：前锚室，竖直布置在山体上；主缆室，倾斜布置在山体前侧，且与前锚室相连通；锚洞，位于前锚室正下方，锚洞沿铅垂向方向开设，且与前锚室连通，锚洞内径自上往下逐渐增大；锚塞体，包括钢构件及混凝土体，钢构件设置于锚洞内底面，混凝土体充填于钢构件上方的锚洞内；主锚缆，穿过主缆室并与钢构件进行连接。本发明的锚洞由于其轴向方向和水平面垂直，可以大大减少锚洞开挖工作量及施工周期，减小坍塌的风险；锚塞体和锚洞内壁楔形配合，接触面积更大，带动周边参与承载岩土范围更大，锚塞体、围岩自重全部能够用来平衡主缆的荷载，大大增加了隧道式锚碇的承载能力。
