Pre-pressing device of hanging basket for cantilever construction bridge support and pre-pressing loading method
The invention provides a pre-pressing device of a hanging basket for a cantilever construction bridge support and a pre-pressing loading method, and belongs to the technical field of bridge construction. A pre-pressing device of a hanging basket for a cantilever construction bridge support comprises a telescopic control mechanism, a piston cylinder barrel unit and a pressing unit. The pressing unit comprises a pressing plate, a water storage cavity is formed in the pressing plate, a plurality of on-off doors are arranged along the water storage cavity at intervals, the water storage cavity is divided into a main pre-pressing cavity in the middle and a plurality of auxiliary pre-pressing cavities on the two sides by the on-off doors, openings are formed in the lower sides of the auxiliary pre-pressing cavities, and the openings are sealed through flexible connecting plates; the piston cylinder barrel unit comprises a vertical barrel and a piston, and the upper end of the piston is connected to the telescopic control mechanism. A hanging basket pre-pressing loading method comprises the following steps that water flows into an on-off door, water enters an auxiliary pre-pressing cavity, after a telescopic control mechanism controls a hydraulic cylinder to gradually pressurize a piston, water in the auxiliary pre-pressing cavity can force a flexible connecting plate at the bottom to expand, and then the flexible connecting plate makes contact with a hanging basket to apply pressure.
本发明提供了一种悬臂施工桥梁支架用挂篮的预压装置及预压加载方法，属于桥梁施工技术领域。悬臂施工桥梁支架用挂篮的预压装置，包括伸缩控制机构、活塞缸筒单元和压紧单元；压紧单元包括施压板，在施压板上设有蓄水腔，沿着蓄水腔间隔设置若干通断门，通断门将蓄水腔分割成中间的主预压腔以及两侧的若干副预压腔，副预压腔的下侧设置有开口，开口通过柔性连接板封闭；活塞缸筒单元包括竖直筒和活塞，活塞的上端连接至伸缩控制机构。一种挂篮预压加载方法，包括以下步骤：通断门内通水，水进入副预压腔，伸缩控制机构控制液压缸对活塞逐步增压后，副预压腔内的水能够迫使底部的柔性连接板柔性连接板膨胀，然后与挂篮接触施加压力。
