Large-section truss type steel structure bridge construction method
The invention relates to the technical field of bridge construction, in particular to a large-section truss type steel structure bridge construction method, which comprises the following steps: S1, firstly, constructing a lower structure of a bridge, including a bridge abutment for supporting an upper structure of the bridge, a bridge pier and a foundation for bearing downward transmission pressure of the bridge abutment and the bridge pier; S2, constructing and building an upper structure of the bridge, wherein the upper structure comprises a bearing structure and a bridge floor; and S3, prefabricating a bearing structure. The construction method is provided for solving the technical problem that in the construction process of the large-section truss type steel structure bridge, the large-section truss type steel structure bridge cannot be in position in one step, the technical problem that the large-section truss type steel structure bridge is difficult to erect in position in one step is solved, and the method is easy and convenient to operate, high in speed, high in truss beam assembling efficiency, accurate in alignment, light in self weight of structure, and high in spanning capacity, and compared with a traditional steel truss, the structure is simple in structure, low in steel consumption, large in overall rigidity, good in joint performance and convenient to apply prestress.
本发明涉及桥梁施工技术领域，尤其涉及一种大断面桁架式钢结构桥梁施工方法，包括以下步骤：S1、首先施工建造桥梁的下部结构，包括用于支撑桥梁上部结构的桥台、桥墩以及用于承载二者下传压力的基础；S2、其次施工建造桥梁的上部结构，包括承重结构以及桥面；S3、预制承重结构；本发明针对大断面桁架式钢结构桥梁施工过程中，不能一步就位时，提供了一种大断面桁架式钢结构桥梁施工方法，解决了大断面桁架式钢结构桥梁架设很难一步就位的技术难题，本方法操作简便、速度快，桁架梁拼装效率高，对位精确，结构自重轻、跨越能力强，与传统钢析架相比，该结构构造简单、用钢量低，结构整体刚度大、节点性能好，且便于施加预应力。
