Permeable pile structure for reinforcing bridge abutment and construction method thereof
The invention discloses a permeable pile structure for reinforcing a bridge abutment and a construction method of the permeable pile structure, and relates to the technical field of existing bridge abutment reinforcement. The water-permeable pile structure comprises a plurality of pile structures and a plurality of water-permeable pipes, the pile structures are suitable for being arranged around the bridge abutment, the pile structures are sequentially connected, the water-permeable pipes penetrate through the pile structures correspondingly, and the pipe walls of the water-permeable pipes are provided with a plurality of communicating holes. By arranging the water-permeable pile structure comprising the multiple pile structures and the multiple water-permeable pipes, anti-liquefaction reinforcement can be conducted on an existing bridge abutment, a drainage channel can be formed by the first cavity, the multiple communicating holes and the second cavity, the dissipation path of water pressure can be increased, foundation soil consolidation can be accelerated, accumulation of excess pore water pressure can be effectively slowed down, and the water-permeable effect is improved. In addition, due to the fact that the bridge abutment is surrounded by the permeable pile structure, transverse expansion of the foundation soil body can be rigidly restrained, shear strain of the foundation soil body is reduced, and the stability of the existing bridge abutment structure is improved.
本发明公开了一种用于加固桥台的透水桩结构及其施工方法，涉及既有桥台加固技术领域。透水桩结构包括：多个桩结构和多个透水管，多个桩结构适于围绕桥台设置，且多个桩结构依次连接设置，多个透水管分别穿设于多个桩结构，透水管的管壁具有多个连通孔。通过设置包括多个桩结构和多个透水管的透水桩结构，能够对既有桥台进行抗液化加固，第一空腔、多个连通孔、第二空腔能够形成排水通道，可以增加水压力的消散路径，以加速地基土体固结，可以有效减缓超孔隙水压的积累，降低地基土体液化的概率，并且，由于桥台被透水桩结构包围，可以使地基土体的横向扩展受到刚性约束，以减小地基土体的剪应变，有利于提升既有桥台结构的稳定性。
