Rib plate type retaining wall abutment and construction method
The invention discloses a rib plate type retaining wall abutment and a construction method. The abutment comprises a pile foundation and a bearing platform connected to the top of the pile foundation,and further comprises at least two T-shaped rib plate components connected to the top of the bearing platform. The T-shaped rib plate component comprises a stand column and a rib plate, wherein one side edge of the rib plate is vertically connected to the inner side edge of the stand column, and the lower edge of the rib plate is flush with the bottom of the stand column. The inner side edges ofthe adjacent T-shaped rib plate components are further in lap joint with soil blocking plates, and the tops of the adjacent T-shaped rib plate components are further connected with an abutment cap. The advantages are that soil pressure borne by the rib plate type retaining wall abutment is balanced through the friction effect between the T-shaped rib plate components and abutment back embankment filling; and compared with a gravity type abutment, the rib plate type retaining wall abutment can greatly reduce masonry amount of the abutment, and the economical efficiency is good. The soil blocking plates are arranged between the T-shaped rib plate components, so that compared with an embedded rib-shaped abutment, the rib plate type retaining wall abutment eliminates a conical revetment in front of the abutment, can effectively enlarge the clearance of the bottom of the bridge or shorten the span of the bridge, and the influence of water flow scouring can be avoided.
本发明公开了一种肋板式挡墙桥台及构筑方法。桥台包括桩基和连接到桩基顶部的承台，还包括至少两个连接到承台顶部的T形肋板构件；T形肋板构件包括立柱和肋板，肋板的一个侧边竖向连接到立柱的内侧边，肋板的下边与立柱的底部平齐；相邻的T形肋板构件的内侧边还搭接有挡土板，相邻的T形肋板构件的顶部还连接有一个台帽。本发明的有益效果在于：肋板式挡墙桥台承受的土压力由T形肋板构件与桥台背路堤填土间的摩擦效应平衡，与重力式桥台相比，能大幅度减小桥台的圬工用量，经济性好。T形肋板构件间设置挡土板，与埋置式肋形等桥台相比，消除了桥台前的锥形护坡，能有效扩大桥底净空或缩短桥梁跨距，而且能避免水流冲刷影响。
