Large-span steel trestle structure and construction method thereof
The invention relates to a large-span steel trestle structure and a construction method thereof. The large-span steel trestle structure comprises a plurality of profile steel reinforcing layers fixedly arranged on a riverbed at intervals in the design direction of a steel trestle. The steel frame is fixedly arranged on the profile steel reinforcing layer; and the bridge deck is fixedly arranged on the plurality of steel frames. According to the steel trestle structure, the profile steel reinforcing layer is fixedly arranged on the riverbed and serves as a foundation of the whole steel trestle structure, the mounting stability of the steel frames is ensured, the steel frames are mounted on the profile steel reinforcing layer, piers are formed for bearing and supporting the bridge deck, and due to the fact that the profile steel reinforcing layer and the steel bars are both of a steel structure, mounting and dismounting are convenient; steel pipe columns do not need to be inserted, construction efficiency is improved, and construction cost is reduced.
本发明涉及一种大跨度钢栈桥结构及其施工方法，包括：沿钢栈桥的设计方向间隔地固设于河床之上的若干个型钢加固层；固设于型钢加固层之上的钢架；固设于若干个钢架之上的桥面板。本发明中在河床上固设型钢加固层，型钢加固层作为整个钢栈桥结构的基础，确保了钢架安装的稳固性，在型钢加固层上安装钢架，形成桥墩供承托和支撑桥面板，由于型钢加固层和钢筋均采用钢结构，因此安装和拆卸较为方便，无需插打钢管柱，提高了施工效率，降低了施工成本。
