Adjustable cantilever bottom die supporting structure and construction method
The invention discloses an adjustable cantilever bottom die supporting structure and a construction method, and relates to the technical field of offshore cast-in-place breast wall cantilever bottom die supporting construction. Comprising a bracket, a bottom die and an adjustable lead screw, two concave clamping grooves are formed in the bracket and serve as stress points to be hung on a high-strength screw rod, the high-strength screw rod is connected with a reserved circular truncated cone nut in a caisson, two supporting legs are arranged at the bottom of the bracket and supported on the outer wall of the caisson after being stressed, and a bottom die walking board is arranged on the rear portion of the bracket. The top of the bracket is connected with multiple sets of vertical adjusting lead screws, horizontal adjusting lead screws and transverse adjusting lead screws, and the upper portions of the vertical adjusting lead screws and the upper portions of the horizontal adjusting lead screws are connected with a bottom die frame to directly bear breast wall concrete loads on the vertical adjusting lead screws and the horizontal adjusting lead screws. The method is suitable for erecting the cast-in-place pier and abutment bottom formwork with the long overhanging size and the large load, tide restriction is reduced, the safety risk of manual operation is avoided, the plane and the elevation can be flexibly adjusted, the quality influence caused by caisson installation deviation is reduced, and the overall construction efficiency is greatly improved.
一种可调节式悬挑底模支撑结构及施工方法，涉及海上现浇胸墙悬挑底模支撑施工技术领域。包括托架、底模、可调节丝杠，所述托架上设置有两个凹形卡槽作为受力点悬挂在高强螺杆上，所述高强螺杆连接沉箱内预留圆台螺母，所述托架上底部设置两个支腿受力后支撑在沉箱外壁上，所述托架上后方设置底模走台，所述托架顶部连接多组竖向调节丝杠、水平调节丝杠、横向调节丝杠，所述竖向调节丝杠和水平调节丝杠上方连接底模框架直接承担上方胸墙混凝土荷载。本发明适用悬挑尺寸较长、荷载较大的现浇墩台底模模板支立，减少潮汐制约，规避人工手动操作的安全风险，可灵活调整平面、高程，减少沉箱安装偏差带来的质量影响，整体施工效率大幅提高。
