Pier perpendicularity deviation reinforcing method based on energy release method
The invention belongs to the technical field of civil engineering, and discloses a pier perpendicularity deviation reinforcing method based on an energy release method. The pier perpendicularity deviation reinforcing method comprises the steps that an energy release groove is constructed and dug in the root of a pier, and then a winch and a steel wire rope are adopted for applying tension in the direction opposite to the pier deviation amount to the top of the pier to correct pier deviation; and after the deviation is recovered, the energy release groove is hooped and reinforced by using high-performance concrete. The pier perpendicularity deviation reinforcing method is novel in conception, the energy release method principle is ingeniously utilized, the energy release groove is constructed and dug in the reasonable position of the pier root, deviation of the pier is corrected through rotation of the pier root under the action of small tension, the stress performance of the pier is improved, and deviation recovery is achieved.
本发明属于土木工程技术领域，公开了一种基于释能法对桥墩垂直度偏位的加固方法，其采用在桥墩根部施工开凿释能槽，然后采用卷扬机和钢丝绳对桥墩顶部位置施加与桥墩偏移量反方向的拉力纠正桥墩偏位；当偏位恢复后，用高性能混凝土对释能槽进行套箍加固。本发明构思新颖，巧妙地利用释能法原理，桥墩根部合理位置施工开凿释能槽，然后在较小拉力的作用下，利用桥墩根部转动来对桥墩偏位进行纠偏，改善桥墩的受力性能，实现偏位恢复。
