Construction method for suspension bridge gravity type anchorage porous annular foundations
The invention discloses a construction method for suspension bridge gravity type anchorage porous annular foundations. The construction method comprises the following steps that the multiple annular foundations are prefabricated; the first layer of annular foundation is put in a to-be-installed position, and soil is taken evenly and symmetrically in a sector area and a wellhole of the first layerof annular foundation till the first layer of annular foundation sinks to the set depth; the second layer of annular foundation is installed on the first layer of annular foundation, head swing rebarson the second layer of annular foundation and head swing rebars on the first layer of annular foundation are bound and connected, a template is supported at joints, and concrete is poured; soil is taken evenly and symmetrically in sector areas and wellholes of the first layer and second layer of annular foundations till the first layer of annular foundation sinks to the set depth; a layer of annular foundation is installed on the topmost layer of annular foundation till the bottom of the first layer of annular foundation reaches the design elevation and is stabilized, and then construction isstopped; pouring of top seal concrete and a cast-in-place cover plate is conducted. Construction safety can be ensured through the suspension bridge gravity type anchorage porous annular foundations.
本发明公开了一种悬索桥重力式锚碇多孔环形基础的施工方法，包括以下步骤：预制多个环形基础；将第一层环形基础放置在待安装位置，并在第一层环形基础的扇形区和井孔内均匀对称取土直至第一层环形基础下沉至设定深度；在第一层环形基础上安装第二层环形基础，将第二层环形基础上的甩头钢筋与第一层环形基础上的甩头钢筋绑扎连接并且在连接处支模板浇筑混凝土；在第一层、第二层环形基础的扇形区和井孔内均匀对称取土，直至第一层环形基础下沉至设定深度；在最上层的环形基础上安装上一层环形基础，直至第一层环形基础底部达到设计高程并稳定后停止施工；浇筑封底混凝土和现浇盖板。该基础能保证施工安全。
