Ultrahigh variable cross-section hollow pier creeping formwork and hollow pier construction method
The invention relates to the technical field of ultrahigh hollow pier construction, in particular to an ultrahigh variable cross-section hollow pier creeping formwork and a hollow pier construction method. Through vertical sliding of the vertical guide rods and the inner climbing frame, it is ensured that the top frame cannot deviate left and right during ascending or descending. Meanwhile, the space between the top frame and the inner climbing frame can be fixed at a certain distance through the locking structure, the inner side frame and the outer side frame are extruded through the connecting rod assembly to achieve die assembly, the bottom of the inner side frame and the bottom of the outer side frame are selectively locked in a one-way mode through a ratchet plate and a pawl plate and a horizontal guide rail, the die assembly strength is ensured, and the die expansion and slurry leakage phenomena are prevented. And split bolts are not adopted, so that mold disassembly and assembly treatment is facilitated, the construction period is shortened, the ultra-high-altitude operation amount of operators is reduced, and safe and rapid construction is ensured. The problems that in the prior art, construction operation of an ultrahigh variable-cross-section hollow pier is complex, and fast and safe construction cannot be achieved are solved.
本发明涉及超高空心墩施工技术领域，具体为超高变截面空心墩爬模及空心墩施工方法。本发明通过竖向导杆和内爬架竖向滑动，确保顶架上行或下行时不会出现左右偏移。同时利用锁止结构能够将顶架和内爬架之间的间距固定在一定距离，经连杆组件挤压内侧架和外侧架实现合模，且内侧架和外侧架的底部通过棘齿板和棘爪板与水平导轨选择性单向锁止，确保合模力度防止涨模漏浆现象。不采用对拉螺栓，方便拆合模处理，缩短工期，减少操作人员超高空作业量，确保安全、快捷施工。用于解决现有技术超高变截面空心墩施工操作复杂，无法实现快捷、安全施工。
