Method for hoisting stiffening beam of suspension bridge
The invention discloses a suspension bridge stiffening beam hoisting method, which comprises the steps of construction equipment installation, standard segment hoisting, end beam hoisting, secondary end beam installation and closure segment hoisting, during end beam hoisting, a cable crane system and a traction swing shifting system are adopted to place the side span side of an end beam on a support through a swing shifting method, the end beam is pre-deviated to a set value, and the end beam is lifted to a set value; then a temporary sling of the temporary hanging system is used for being connected with the end beam and tensioning the end beam, then the cable rope hanging system is gradually lowered, the temporary sling gradually replaces the pulling force of the cable rope hanging system on the end beam, finally the cable rope hanging system and the end beam are disconnected, and then the traction swing moving system is disconnected; and after the cable crane system is separated from the end beam, the tension to the end beam is kept through the temporary hanging system, so that the end beam is stabilized at the mounting position. The method has the effects that the supporting difficulty and the hoisting cost of the end beam in the hoisting process of the suspension bridge stiffening beam are reduced, and the construction efficiency is improved.
本申请公开了一种悬索桥加劲梁的吊装方法，其包括步骤施工机具安装、标准节段吊装、端梁吊装、次端梁安装和合龙段吊装，端梁吊装时，采用缆索吊系统和牵引荡移系统通过荡移法将端梁的边跨侧安放至支座上，端梁预偏设定值，再使用临时吊挂系统的临时吊索连接端梁并拉紧端梁，再逐渐下放缆索吊系统，临时吊索逐渐替代缆索吊系统对端梁的拉力，最后解除缆索吊系统和端梁的连接，再解除牵引荡移系统；缆索吊系统脱离端梁后通过临时吊挂系统保持对端梁的拉力，从而使得端梁稳定在安装位置。本申请具有降低悬索桥加劲梁吊装过程中端梁的支撑难度、吊装成本以及提高施工的效率的效果。
