High pier zero block counter-force pre-pressing method based on combined bracket
The invention provides a high pier zero block counter-force pre-pressing method based on a combined bracket. The method comprises the following steps of installing an embedded climbing cone and reserving a finish rolling thread steel hole channel, installing an upper shear key and a lower shear key, installing a bracket straight support and a bracket inclined support, laying a distribution longitudinal beam, laying a distribution cross beam, installing a tensioning unit, installing a reaction frame, installing a vertical opposite-pull rod and obtaining prepressing deformation data. The construction problem that the universality is not achieved when the bearing platform is used as a supporting point for counter-force prepressing is solved, and meanwhile the device has the advantages of being easy to install, convenient to disassemble, economical, efficient, high in universality, wide in application range and capable of improving the construction efficiency.
本发明提供了一种基于组合式托架的高墩零号块反力预压方法，本发明包括以下步骤：安装预埋爬锥和预留精轧螺纹钢孔道、安装上、下剪力键、安装托架直撑和托架斜撑、铺设分配纵梁、铺设分配横梁、安装张拉单元、安装反力架、安装竖直对拉杆和获取预压变型数据。本发明解决了利用承台作为支点进行反力预压不具有通用性的施工难题，同时具有安装简单、拆卸方便、经济高效、通用性高、适用面广和提高施工效率的优点。
