Sliding lifting method for bridge steel arch
The invention discloses a slippage lifting method for a bridge steel arch. The slippage lifting method comprises the steps that firstly, the steel arch linearly and accumulatively slides along a bridge floor; transversely sliding for 8.06 m to the projection position of the steel arch; a lifting support is arranged at the high point of the hoisted steel arch at one end, two lifting points are arranged on the lifting support, and the steel arch at the other end is hinged through a rotating shaft; and the steel arch is lifted and overturned to adjust the posture to a designed form, and finally the steel arch is lifted to a designed elevation. The sliding and lifting rotation construction technology of the steel arch is ingeniously applied to construction of the special-shaped landscape bridge with the terrains and complex conditions and very harsh conditions, and precious experience is provided for construction of follow-up landscape bridges or bridge projects with similar terrains and construction conditions.
本发明公开了一种用于桥梁钢拱的滑移提升方法，包括：首先将钢拱沿桥面直线累积滑移；再横向滑移8.06m至钢拱投影位置；在分别在一端吊装好的钢拱高点设置提升支架，提升支架上设有2个提升点，另一端钢拱靠转轴铰接；一端提升钢拱另一端随之转动，提升翻转钢拱调整姿态至设计形态，最后提升至设计标高。钢拱的滑移、提升转体施工技术，巧妙运用在了地形及其复杂、条件非常苛刻的异型景观桥梁的施工中，给后续景观桥梁或类似地形环境、施工条件的桥梁项目的施工提供了宝贵经验。
