Grid-shaped suspension bridge tunnel type anchorage provided with pore type viscous dampers and construction method of grid-shaped suspension bridge tunnel type anchorage
The invention relates to the technical field of suspension bridge tunnel type anchors, in particular to a grating-shaped suspension bridge tunnel type anchor provided with a pore type viscous damper and a construction method of the grating-shaped suspension bridge tunnel type anchor. The grating-shaped suspension bridge tunnel type anchor comprises an anchor plug body and a rock mass, and the pore type viscous damper is installed between the anchor plug body and the rock mass; and the grids on the side surfaces, the bottom surface and the top curved surface of the anchor plug body are embedded with the square bulges uniformly arranged on the inner surface of the rock mass. According to the anchor provided by the invention, the grating-shaped cross section on the surface of the anchor plug body is embedded with the bulge of the surrounding rock, so that the side friction resistance between the anchor structure and the surrounding rock is increased, higher bearing capacity is obtained, and the resistance to the drawing force of the main cable of the suspension bridge can be improved when the rock mass condition at the building part of the anchor plug body is poor. The hole type viscous damper is arranged in the center of the protrusion of the rock mass, the shock resistance of the anchor plug body is improved, a good shock insulation effect can be achieved when an earthquake occurs, and the applicability of the tunnel type anchorage in an earthquake-prone area is improved.
本发明涉及悬索桥隧道式锚碇技术领域，具体为一种安装有孔隙式粘滞阻尼器的格栅状悬索桥隧道式锚碇及其施工方法，包括锚塞体和岩体，所述锚塞体与岩体之间安装有孔隙式粘滞阻尼器，所述锚塞体的侧面、底面及顶部曲面的格栅与岩体内表面均匀排列的方形凸起之间相嵌合。本发明提供的锚碇通过锚塞体表面的格栅状截面与围岩凸起处的相互嵌合，增大了锚碇结构与围岩之间的侧摩阻力，获得更大承载能力，在锚塞体修建处的岩体条件较差时，能提高对于悬索桥主缆拉拔力的抵抗能力。本发明通过在岩体凸起的中心处装置孔隙式粘滞阻尼器，提高了锚塞体的抗震能力，在地震发生时能起到良好的隔震作用，提高了隧道式锚碇在地震多发区域的适用性。
