Combined abutment structure for temporary trestle
The invention discloses a combined abutment structure for a temporary trestle. The structure comprises a pedestal, a steel pipe pile, a shear connector, a bearing beam and a trestle girder. The bearing beam is mounted on the pedestal, the end part of the trestle girder is mounted on the bearing beam, the shear connector is arranged in an embedded section of the pedestal where the steel pipe pile is positioned, and the shear connector extends outwards from the steel pipe pile. The steel pipe pile and the L-shaped gravity type bridge abutment are combined, the shear connector is arranged in theembedded section of the steel pipe pile, the steel pipe pile and the L-shaped gravity type bridge abutment are stressed together, so that the overall rigidity and stability of the bridge abutment structure are improved, and sedimentation and sliding deformation of abutment back filling soil can be stably prevented.
本发明公开了一种用于临时栈桥的组合式桥台结构，包括台座、钢管桩、抗剪连接件、垫梁和栈桥主梁，垫梁安装在台座上，栈桥主梁的端部安装在垫梁上，抗剪连接件设置在钢管桩位于台座的埋入段内，且该抗剪连接件从钢管桩向外延伸。本发明采用钢管桩和L型重力式桥台相结合，并在钢管桩的埋入段内设置抗剪连接件，实现二者共同受力，提高了桥台结构的整体刚度和稳定性，能够稳固地阻止台背填土发生沉降和滑移变形。
