Low lower tower column bridge tower and construction method
The invention discloses a low lower tower column bridge tower and a construction method, and relates to the technical field of bridge engineering. The two limb tower columns are symmetrically arranged on the bearing platform, each limb tower column comprises an upper tower column and a lower tower column, the two limb lower tower columns incline outwards by a set angle along the transverse bridge, the tops of the two limb lower tower columns are connected with the bottoms of the two limb upper tower columns respectively, and the tops of the two limb upper tower columns are connected together; the two ends of the lower cross beam are arranged at the joints of the upper tower columns and the lower tower columns of the two limbs respectively and used for supporting the main beams; and the pier column is arranged on the bearing platform and supports the lower cross beam. The rigidity of the lower cross beam is increased, so that the load borne by the lower cross beam is partially transmitted to the pier column, the load borne by the tower column is dispersed, and the stress of the tower column is improved. The problems that in the prior art, when the distance between a lower cross beam and the tower bottom is small due to the limitation of the terrain and the bridge floor elevation, the lower cross beam and a lower tower column generate a frame effect, the application efficiency of cross beam prestress is reduced, and the design difficulty is increased are solved.
本发明公开了一种低矮下塔柱桥塔及施工方法，涉及桥梁工程技术领域，该低矮下塔柱桥塔包括：承台；两肢塔柱，对称设置在承台上，每肢塔柱均包括上塔柱和下塔柱，两肢下塔柱沿横桥向外倾设定角度，顶部分别与两肢上塔柱的底部连接，两肢上塔柱的顶部连接在一起；下横梁，其两端分别设置在两肢上塔柱与下塔柱的连接处，用于支撑主梁；墩柱，其设置在承台上，并支撑下横梁。增大了下横梁刚度，使下横梁承受的荷载部分传递到墩柱，分散了塔柱所承受的荷载，改善塔柱受力。解决了现有技术中存在当地形与桥面标高限制，下横梁距离塔底较小时，下横梁与下塔柱产生框架效应，降低了横梁预应力的应用效率，增大设计难度的问题。
