Bridge T-shaped underground diaphragm wall foundation and construction method
The invention belongs to the technical field of bridge and culvert foundation structures, and particularly relates to a T-shaped underground diaphragm wall foundation of a bridge and a construction method. The foundation comprises an underground diaphragm wall, a beam body upper structure, a cap beam, a support, a bridge deck slab and a bridge abutment transition slab. The underground diaphragm wall comprises a strip wall type underground diaphragm wall and a T-shaped underground diaphragm wall; the strip wall type underground diaphragm wall is arranged in the middle of the bottom of the whole beam body upper structure, and the T-shaped underground diaphragm walls are symmetrically arranged on the two sides of the strip wall type underground diaphragm wall. Spaces between the two sides of the strip wall type underground diaphragm wall and the T-shaped underground diaphragm wall are used for digging expressways under the bridge; the bridge deck slab is arranged at the top of the beam body superstructure, and the bridge abutment transition slab is arranged on the outer sides of the tops of the two T-shaped underground diaphragm walls; the tops of the T-shaped underground diaphragm wall and the strip wall type underground diaphragm wall are connected with the upper structure of the beam body through cap beams and supports. The construction procedures of the bridge foundation are reduced, the construction efficiency of the bridge foundation is higher, and the construction speed is higher.
本发明属于桥涵基础结构技术领域，尤其涉及一种桥梁T形地下连续墙基础及施工方法。所述基础包括地下连续墙、梁体上部结构、帽梁、支座、桥面板和桥台搭板；地下连续墙包括条壁式地下连续墙和T形地下连续墙；条壁式地下连续墙居中设在整个梁体上部结构的底部，T形地下连续墙对称式设在条壁式地下连续墙的两侧；条壁式地下连续墙两侧与T形地下连续墙之间的空间均用于挖设桥下高速公路；梁体上部结构顶部设有所述桥面板，两个T形地下连续墙的顶部外侧设有所述桥台搭板；T形地下连续墙和条壁式地下连续墙的顶部均通过帽梁和支座与梁体上部结构连接。本发明减少了桥梁基础的施工工序，桥梁基础的施工效率更高，施工速度更快。
