The invention provides a track-adjustable supporting leg for bridge construction and a track switching method. A lifting mechanism is arranged on a walking track through a plurality of walking mechanisms, and the walking track is arranged on a pier; the lifting mechanism is connected with the jacking frame, the jacking frame is in sliding connection with the walking support, the lower end of the walking support is connected with the walking mechanism, the walking mechanism is arranged on the walking track, the walking track is arranged on a pier through a plurality of track supporting legs, the walking supporting legs are further arranged, and the upper portions of the walking supporting legs are connected with the jacking frame through a plurality of main jacking oil cylinders. The middle of the walking supporting leg is connected with the walking support through a plurality of supporting leg lifting oil cylinders. A jacking platform can enable a platform body to be separated from the water surface, the influence of severe sea conditions is avoided during operation, a crawler crane on the platform can achieve high-precision hoisting, however, under the displacement working condition, a construction window period still needs to be found, a wharf engineering shoreline is long, the overall construction displacement frequency is large, and meanwhile the length of supporting legs is limited; and wharf construction of deep-water, deep and soft stratums is difficult to adapt.

    本发明提供一种用于桥梁施工的轨道可调支腿及轨道转换方法,提升机构通过多个行走机构设置在行走轨道上,行走轨道设置在桥墩上;提升机构与顶升架连接,顶升架与行走支架滑动连接,行走支架下端与行走机构连接,行走机构设置在行走轨道上,行走轨道通过多个轨道支腿设置在桥墩上,还设有行走支腿,行走支腿上部位置与顶升架通过多个主顶升油缸连接,行走支腿中部位置通过多个支腿提升油缸与行走支架连接。顶升平台能将平台主体脱离水面,作业时避免恶劣海况的影响,平台上的履带吊能实现高精度的吊装,但其移位工况下仍需寻找施工窗口期,码头工程岸线较长,整体施工移位次数较多,同时其支腿长度有限,也难以适应深水深厚软弱地层的码头施工。
