Technical Information
Technical parameters
Technical approach
- The jacking scheme is developed according to structural condition, support arrangement, target elevation, and construction-stage constraints.
- Hydraulic jacking, temporary support, staged lifting, and monitoring are coordinated to control structural response during elevation adjustment.
- Jacking sequence, load transfer, and support replacement measures should be confirmed through project-specific assessment and design.
Key control items
- Structural safety before, during, and after jacking.
- Jacking synchronization, elevation control, and deviation correction.
- Temporary support stability and load transfer path.
- Monitoring of settlement, deformation, and support conditions.
技术参数
技术实施要点
- 顶升方案应结合结构状态、支撑条件、目标高程和施工阶段约束进行确定。
- 通过液压顶升、临时支撑、分阶段顶升和施工监测协同控制结构响应。
- 顶升顺序、荷载转换和支座更换措施应结合具体项目评估和设计确定。
重点控制内容
- 顶升前、顶升中和顶升后的结构安全。
- 顶升同步性、高程控制与偏差纠正。
- 临时支撑稳定性和荷载传递路径。
- 沉降、变形和支撑状态监测。
