Pedestrian overpass and construction method thereof
The invention relates to the technical field of bridges and structures, and discloses a pedestrian overpass and a construction method thereof. The foundation assembly comprises a foundation main body and an embedded part arranged in the foundation main body, the embedded part comprises an embedded steel plate and a reinforcing steel frame, the embedded steel plate is arranged on the top surface of the foundation main body, and the reinforcing steel frame is connected to the bottom surface of the embedded steel plate; the pier comprises a steel pier column and a filling part filled in the steel pier column, the bottom of the pier is connected to the top of the foundation assembly, and the bottom of the steel pier column is welded to the embedded steel plate; the girder is welded to the top of the pier; a plurality of pier bottom stiffening ribs which are arranged along the steel pier column at intervals are welded between the embedded steel plate and the bottom of the steel pier column; a plurality of pier beam stiffening ribs spaced along the steel pier column are welded between the main beam and the top of the steel pier column; in-column stiffening ribs are further arranged along the inner circumferential wall of the steel pier column. The mechanical property and rigidity of the pedestrian overpass are improved, the fundamental frequency is improved, resonance of the pedestrian overpass is reduced, and safety and comfort are met.
本发明涉及桥梁及结构技术领域，公开了一种人行天桥及其施工方法，人行天桥包括基础组件、桥墩及主梁；基础组件包括基础主体及设于基础主体内的预埋件，预埋件包括预埋钢板及加强钢架，预埋钢板设于基础主体的顶面，加强钢架连接于预埋钢板的底面；桥墩包括：钢墩柱及填充于钢墩柱内的填充部，桥墩的底部连接于基础组件的顶部，钢墩柱的底部与预埋钢板焊接；主梁焊接于桥墩的顶部；预埋钢板与钢墩柱的底部之间焊接有多个沿钢墩柱间隔设置的墩底加劲肋；主梁与钢墩柱的顶部之间焊接有多个沿钢墩柱间隔的墩梁加劲肋；沿钢墩柱的内周壁还设有柱内加劲肋。通过提升人行天桥的力学性能和刚性，提高基频，减小人行天桥共振，满足安全性和舒适性。
