Construction method for main tower of cable-stayed bridge
The invention provides a cable-stayed bridge main tower construction method, a cable-stayed bridge main tower comprises a pair of lower tower columns, a pair of upper tower columns, a lower cross beam and an upper cross beam, the two ends of the lower cross beam are connected to the joints of the upper tower columns and the lower tower columns on the two sides of the main tower respectively, and the two ends of the upper cross beam are connected with the top ends of the two upper tower columns respectively; the main tower construction method comprises the following steps that 1, a lower tower column is constructed, and the lower tower column is constructed in a rollover mode; 2, a lower cross beam is constructed, the lower cross beam is constructed through a support method, concrete of the lower cross beam is poured in multiple sections, and the prestressed tendons of the corresponding parts are tensioned after pouring; 3, an upper tower column is constructed, the upper tower column is constructed through a hydraulic creeping formwork, the segmented pouring height of the hydraulic creeping formwork is combined with the position of the steel anchor beam embedded part to be segmented, and the upper tower column is poured to the position below the upper cross beam; 4, an upper cross beam is constructed, the upper cross beam is constructed through a support method, the bearing capacity and stability of a support system are checked, calculated and analyzed, and the design of the support system is perfected; and the construction efficiency of the cable-stayed bridge main tower is improved.
本发明提供一种斜拉桥主塔施工方法，斜拉桥主塔包括一对下塔柱、一对上塔柱、下横梁与上横梁，下横梁的两端分别连接在主塔两侧的上、下塔柱交接处，上横梁的两端分别与两个上塔柱的顶端连接；主塔施工方法包括以下步骤：步骤1，施工下塔柱，下塔柱采用翻模施工；步骤2，施工下横梁，下横梁采用支架法施工，下横梁混凝土分多节浇筑，浇筑后张拉对应部分的预应力筋；步骤3，施工上塔柱，上塔柱采用液压爬模施工，液压爬模的分节浇筑高度结合钢锚梁预埋件位置进行分段，上塔柱浇筑至上横梁下方；步骤4，施工上横梁，上横梁采用支架法施工，对支架系统的承载能力、稳定性进行验算分析，并完善支架系统的设计；提高了斜拉桥主塔的施工效率。
