Arch bridge cantilever construction system and method
The invention discloses an arch bridge cantilever construction system and method, and aims to save the construction period of an arch bridge cantilever and reduce the input of buckling anchor cables. Therefore, the arch bridge cantilever construction method provided by the invention comprises the following steps: constructing an anchorage and a buckling tower on a junction pier; and constructing a main arch ring, taking the anchorage as a rear anchor system of the main arch ring, connecting the anchorage with the buckling tower in an anchoring mode through an anchor cable, and connecting the other side of the buckling tower with the main arch ring in an anchoring mode through a cable-stayed buckling cable, wherein the main arch ring is formed by pouring multiple sections of arch box cantilevers, and in the construction process of the main arch ring, all sections of arch boxes of the main arch ring are alternately tensioned through pre-stressed steel beams and cable-stayed buckle cables.
本发明公开了一种拱桥悬臂施工系统及方法，旨在节约拱桥悬臂的工期以及减少扣锚索的投入量。为此，本发明提供的拱桥悬臂施工方法，包括如下步骤：施工锚碇以及交界墩上的扣塔；施工主拱圈，利用锚碇作为所述主拱圈的后锚系统，将所述锚碇通过锚索与所述扣塔锚固连接，所述扣塔另一侧通过斜拉扣索与所述主拱圈锚固连接；其中，所述主拱圈由多段拱箱悬臂浇筑而成，所述主拱圈施工过程中，通过预应力钢束和斜拉扣索对所述主拱圈的各节段拱箱交替进行张拉。
