Pre-pressing device and pre-pressing method for high pier support
The invention relates to the technical field of bridge engineering high pier construction, in particular to a pre-pressing device and method for a high pier support. The pre-pressing device for the high pier support comprises a spliced partial load beam, a jack, a steering device and a plurality of steel strands. The spliced partial load beam is arranged on the top surface of the bracket group, and the jack is matched with the bridge pier; one ends of the multiple steel strands are arranged on the spliced partial load beam, the other ends of the multiple steel strands penetrate through the steering device, the steering device is configured to gather the multiple steel strands penetrating through the steering device to form a steel cable bundle, and the steel cable bundle is connected with the jack; and the jack is used for tensioning the steel strand, so that the steel strand transmits tensile force to the spliced partial load beam, pressure is applied to the support, and prepressing of the support is completed. In this way, the defects of an existing support pre-pressing method can be overcome, support pre-pressing can be completed only through one jack, the construction steps are simple, control is easy, and the construction efficiency is high.
本发明涉及桥梁工程高墩施工技术领域，具体而言，涉及一种用于高墩支架的预压装置和预压方法。用于高墩支架的预压装置包括拼接式分载梁、千斤顶、转向装置和多个钢绞线；拼接式分载梁设置在支架组的顶面，千斤顶与桥墩配合；多个钢绞线的一端设置在拼接式分载梁上，多个钢绞线的另一端穿设转向装置，且转向装置被配置为能够将穿设转向装置后的多个钢绞线聚拢以形成钢索束，钢索束与千斤顶连接；千斤顶对钢绞线进行张拉，以使钢绞线将拉力传递到拼接式分载梁上，从而对支架施加压力，以完成对支架预压。如此能够针对现有支架预压法的不足，仅使用一个千斤顶即可完成支架预压，施工步骤简单，易于控制，施工效率高。
