Large cooling tower seismic isolation foundation structure and construction method thereof
The invention discloses a large cooling tower seismic isolation foundation structure and a construction method thereof, and belongs to the technical field of buildings. A seismic isolation foundationcomprises a bottom plate pre-buried underground, an inner ring beam, an outer ring beam and a movable ring beam used for supporting a cooling tower, and the movable ring beam is coaxially arranged between the inner ring beam and the outer ring beam; a cross-shaped sliding groove formed by a first sliding groove and a second sliding groove is formed in the upper surface of the bottom plate, the bottom of the movable ring beam is supported on the bottom plate through a first sliding block and a second sliding block, a first damper is arranged between the movable ring beam and the inner ring beam, and a second damper is arranged between the movable ring beam and the outer ring beam. The structure is used for supporting the bottom of the cooling tower so that the cooling tower can move in thetransverse direction and the longitudinal direction, shock absorption can be achieved, and the influence of earthquake factors on the cooling tower is weakened.
本发明公开了一种大型冷却塔隔震基础结构及其施工方法，属于建筑技术领域，隔振基础包括预埋在地面下的底板、内环梁、外环梁以及用于支撑所述冷却塔的活动环梁，所述活动环梁同轴设置于内环梁与外环梁之间，所述底板的上表面开设有由第一滑槽和第二滑槽构成的十字型滑槽，所述活动环梁的底部通过第一滑块和第二滑块支撑于所述底板，所所述活动环梁与内环梁之间设置有第一阻尼器，所述活动环梁与外环梁之间设置有第二阻尼器。本发明结构用于冷却塔的底部进行支撑，使其能沿横向和纵向活动并进行减震，减弱地震因素对冷却塔的影响。
