Construction method for cantilever splicing and hoisting of crawler crane of cable-stayed bridge
The invention discloses a cable-stayed bridge crawler crane suspension splicing hoisting construction method, and relates to the technical field of bridge engineering construction.The crawler crane suspension splicing hoisting is adopted, the characteristic that the crawler crane can move at any time is utilized, the crawler crane is moved to a proper position of a bridge floor for hoisting, equipment does not need to be customized, the crawler crane is fixed to the bridge floor, and independent operation can be achieved; a series of special ships are not needed, segment division is small, transportation is relatively convenient, the hoisting weight is reduced, the hoisting difficulty is reduced, the hoisting safety coefficient is improved, compared with construction methods such as floating cranes and full-rotation bridge floor cranes, the requirements for machines, seasons and environments are low, dependence is not high, crawler crane stations are located on a bridge, river channels are not needed, and the construction cost is low. The problem of a hoisting site is solved without erecting a bracket, the crawler crane is used for suspension splicing and hoisting, and after the closure section is hoisted, the crawler crane can be quickly withdrawn to the approach bridge by utilizing the convenience of the crawler crane.
本发明公开了一种斜拉桥履带吊悬拼吊装施工方法,涉及桥梁工程施工技术领域，本发明中通过采用履带吊悬拼吊装，可利用履带吊自身可随时移动的特点，移动到桥面合适位置进行吊装，不需要定制设备和固定到桥面，可以单独作业，不需要伴有系列的专用船舶，而且节段划分较小，运输相对便捷，减小了吊装重量，从而降低了吊装难度，提高了吊装安全系数，相比浮吊、全回转桥面吊等施工方法，对机械、季节、环境要求较低，依赖性不强，履带吊站位于桥上，不需要占用河道，也不需要搭设支架，解决了吊装场地问题，使用履带吊悬拼吊装，在吊装完合龙段后，可利用履带吊自身便捷性快速将履带吊撤回至引桥处。
