Cantilever type pier and construction method
The invention discloses a cantilever type pier. The cantilever type pier comprises a bearing platform, a pier column and supporting padstones. The pier column comprises a stand column and a cantilever connected to one side of the upper end of the stand column, and the stand column is arranged on the bearing platform. The supporting padstones are arranged at the tops of the stand column and the cantilever arm, the center line of a line formed by the two supporting padstones and the center line of the stand column are eccentrically arranged, and the center line of the stand column and the center line of the bearing platform are eccentrically arranged. The cantilever arm is formed on one side of the upper end of the stand column of the pier column, so that the problems that when an existing building exists beside a rail transit elevated frame, construction is difficult, and the structure is complex are solved. Meanwhile, the center line of a line formed by the two supporting padstones is eccentrically arranged with the center line of the stand column, and the center line of the stand column is eccentrically arranged with the center line of the bearing platform, so that the bearing platform is in a state close to axial compression under dead load. The cantilever type pier and the construction method have the advantages of being simple in structure and convenient to construct.
本申请公开了一种挑臂型桥墩，包括承台、墩柱以及支撑垫石。墩柱包括立柱和连接在立柱上端一侧的挑臂，立柱设置在承台上；支撑垫石设置在立柱和挑臂的顶部，两支撑垫石形成的线路的中心线与立柱中心线偏心设置，立柱中心线与承台中心线偏心设置。通过在墩柱的立柱上端一侧形成挑臂，以解决当轨道交通高架旁存在既有建筑时，存在施工困难、结构复杂的问题。同时通过两支撑垫石形成的线路的中心线与立柱中心线偏心设置，立柱中心线与承台中心线偏心设置，使承台处于恒载下接近轴向受压的状态。本申请的一种挑臂型桥墩及施工方法，具有结构简单、便于施工的优点。
