Steel truss girder cantilever assembling method
The invention belongs to the technical field of bridge construction, and particularly relates to a steel truss girder cantilever assembling method which comprises the following steps: step 1, constructing a first main pier foundation, a second main pier foundation and pier bodies to a main bridge supporting padstone; secondly, a steel truss girder rod piece storage area, a pre-splicing field and a girder transporting shortcut are arranged on the right side of the second main pier, and a lifting station is arranged on one side of the second main pier. According to the method, high-cost, high-risk and high-environmental-pollution foundation treatment work which is caused by treatment of a soft sludge spoil field in a mountainous area and greatly prolongs the construction period when a large crawler crane and a gantry crane are assembled is not needed, so that the cost is saved, the construction period is shortened, the safety risk caused by secondary environmental pollution and differential settlement of the foundation to large equipment can be avoided, and the construction period is shortened. And meanwhile, the steel truss girder can be installed and constructed through small equipment, the construction amount is small, the overall efficiency is high, the construction period is effectively shortened, and the construction cost is low.
本发明属于桥梁施工技术领域，尤其是涉及一种钢桁梁悬臂拼装方法，包括步骤一：施工第一主墩和第二主墩基础及墩身至主桥支承垫石处；步骤二：在第二主墩右侧设置钢桁梁杆件存放区、预拼场及运梁便道，在第二主墩一侧设置提升站。本发明无需使用大型履带吊和龙门吊拼装时因处理山区软弱淤泥质弃土场带来的高成本、高风险、高环境污染和大幅延长工期的地基处理工作，即节约成本，缩短工期，又能避免环境二次污染和地基不均匀沉降给大型设备带来的安全风险，并有效降低了拆卸大型设备的安全风险，同时小型设备即可完成钢桁梁安装施工，施工量小，整体效率高，有效缩短工期，施工成本较低。
