Compatible abutment, construction method thereof and construction method for transforming abutment into pier
The invention discloses a compatible abutment which comprises compatible pile foundations, a compatible bearing platform, pier embedded steel bars, pile foundations and an abutment body. The top endsof the plurality of compatible pile foundations jointly support the compatible bearing platform. A plurality of pier embedded steel bars and abutment body embedded steel bars which are vertically arranged are embedded and fixed on the top surface of the bearing platform; stirrups are bound on the plurality of pier embedded steel bars; more than one pile foundation is arranged on each of the two sides of the whole of the compatible pile foundations and the compatible bearing platform; a bridge abutment body is jointly supported by the top face of the compatible bearing platform and the top endsof the compatible pile foundations on the two sides, the bridge abutment body is connected with the bearing platform through bridge abutment body embedded steel bars, and the pier embedded steel barsare embedded in the bridge abutment body. The invention further provides a construction method of the compatible abutment and a construction method for transforming the compatible abutment into a pier. The problem that the bridge abutment is converted into the bridge pier in the viaduct modification implementation process is solved, the requirements of bridge modification construction are effectively met, and a large number of waste projects of the upper structure and the lower structure are avoided on the premise that the structural stress and the using function are met.
一种兼顾式桥台，包括兼顾桩基、兼顾承台、桥墩预埋钢筋、桩基、桥台台身；多根兼顾桩基的顶端共同支撑有兼顾承台，兼顾承台的顶面预埋固定有多根竖立设置的桥墩预埋钢筋和桥台台身预埋钢筋，多根桥墩预埋钢筋上绑扎有箍筋，多根兼顾桩基和兼顾承台的整体两侧均设有一根以上的桩基，兼顾承台的顶面和两侧桩基的顶端共同支撑有桥台台身，桥台台身通过桥台台身预埋钢筋与兼顾承台连接，桥墩预埋钢筋埋置于桥台台身之内。还提供了兼顾式桥台的施工方法以及改造成桥墩的施工方法。本发明解决了高架桥梁改造实施过程中桥台转变为桥墩的难题，有效兼顾了桥梁改造建设的需求，在满足结构受力和使用功能的前提下，避免了上、下部结构大量的废弃工程。
