Asymmetric cable buckling and hanging construction system for arch bridge in mountainous area and construction method of asymmetric cable buckling and hanging construction system
The invention discloses an asymmetric cable buckling and hanging construction system for an arch bridge in a mountainous area and a construction method thereof.The construction system comprises a step type anchorage and a step type hollowed-out anchorage which are arranged on the large-mileage side of the mountainous area, and a tower, a buckling cable ground anchor and a concrete anchorage which are arranged on the small-mileage side of the mountainous area; the step type anchorage comprises a step type anchorage concrete layer arranged on the hardened rock stratum and first anchor beams installed on the step type anchorage concrete layer, and the first anchor beams are anchored to different step slopes of the step type anchorage concrete layer through pre-stressed anchor cables. The stepped hollow anchorage comprises two stepped anchorage concrete layers and second anchor beams, the two stepped anchorage concrete layers are oppositely arranged in a spaced mode, the second anchor beams are installed on the two stepped anchorage concrete layers, the second anchor beams are anchored on the stepped anchorage concrete layers through steel strands, and the second anchor beams are connected with arch ribs of the arch bridge through buckle cables. The method has the advantage that when the tower is not arranged on the large-mileage side of the mountainous area, the hoisting reliability of the arch rib is ensured.
本发明公开了一种山区拱桥的不对称缆索扣挂施工系统及其施工方法，施工系统包括设于山区的大里程侧的台阶式锚碇和台阶型镂空式锚碇，以及设于山区的小里程侧的塔架、扣索地锚和混凝土锚碇，台阶式锚碇包括设于硬化岩层上的台阶式锚碇混凝土层以及安装在台阶式锚碇混凝土层上的第一锚梁，第一锚梁通过预应力锚索分别锚固在台阶式锚碇混凝土层不同的台阶斜面上；台阶型镂空式锚碇包括两个相对间隔设置台阶式锚碇混凝土层以及安装在两个台阶式锚碇混凝土层上的第二锚梁，第二锚梁通过钢绞线锚固在台阶式锚碇混凝土层上，第二锚梁通过扣索同拱桥的拱肋连接。本发明的优点是：在山区大里程侧不设置塔架时，保证拱肋吊装的可靠性。
