Bridge thin-wall high-pier walking type jacking formwork and construction method thereof
The invention discloses a bridge thin-wall high-pier walking type jacking formwork and a construction method thereof.The formwork comprises a truss steel platform, the bottom of the truss steel platform is connected to a supporting steel column and supported by the supporting steel column, the supporting steel column is supported by an upper supporting beam and a lower supporting beam which are supported on the inner wall of a thin-wall pier column, and a jacking oil cylinder is arranged between the upper supporting beam and the lower supporting beam; alternate jacking of the upper supporting beam and the lower supporting beam is controlled through stretching and retracting of the jacking oil cylinder, formwork overturning and lifting of the operation platform can be achieved, cooperation of a tower crane or a crane is not needed, the cost input of construction equipment can be effectively reduced, construction safety and quality are better guaranteed, the construction efficiency of high piers is obviously improved, and the construction cost is reduced. The method has the advantages of high construction efficiency, low safety risk, guaranteed quality, high overall stability, low extra consumption and the like.
一种桥梁薄壁墩高墩步履式顶升模架及其施工方法，模架包括桁架钢平台，桁架钢平台底部连接于支撑钢柱，由支撑钢柱支撑，支撑钢柱被支撑于薄壁墩柱内壁的上支撑梁和下支撑梁所支撑，上支撑梁与下支撑梁之间设有顶升油缸，通过顶升油缸的伸出和缩回控制上支撑梁和下支撑梁的交替顶升，即可实现翻模和作业平台的提升，无需塔吊或吊车配合，可有效降低施工设备成本投入，不仅施工安全和质量更有保障，且明显提高了高墩的施工效率，具有施工工效高、安全风险低、质量有保障、整体稳定性高以及额外消耗低等优点。
