Steel corrugated plate composite structure for high fill or large span
The invention relates to a steel corrugated plate composite structure for high filling or large span. The steel corrugated plate composite structure comprises an arc-shaped outer-layer steel corrugated plate and an arc-shaped inner-layer steel corrugated plate, wherein the arc-shaped outer-layer steel corrugated plate and the arc-shaped inner-layer steel corrugated plate are integrally formed by annularly lapping single steel corrugated plates which are produced in a standardized manner in a factory, splicing the single steel corrugated plates through high-strength bolts and then longitudinally splicing the single steel corrugated plates in a staggered-joint splicing manner. The two layers of steel corrugated plates are connected together through long bolts, the outer-layer steel corrugated plate and the inner-layer steel corrugated plate are connected with corresponding factory prefabricated and assembled concrete foundations through angle steel respectively, foam concrete is poured between the outer-layer steel corrugated plate and the inner-layer steel corrugated plate, an integral structure is formed, and then a waterproof layer is made. By adopting the flexible steel corrugated plate and the rigid concrete structure, the requirement of the steel corrugated plate bridge culvert for stress can be improved, the overall bearing capacity of the structure is improved, the problem that the structure is unstable due to the fact that the thickness of a high-fill and large-span steel corrugated plate cannot be achieved by a machining process is solved, standardized production is achieved, the construction period is shortened, and the construction cost is reduced. Mining of cement and sand is reduced, and environmental protection is facilitated.
本发明专利涉及用于高填方或大跨径的钢波纹板复合结构，包括工厂标准化生产的单片钢波纹板环形搭接，采用高强螺栓拼接，后纵向采用错缝拼装的形式拼接形成整体的弧形的外层钢波纹板和弧形的内层钢波纹板。采用长螺栓将两层钢波纹板连接在一起，且外层、内层钢波纹板分别与相应的工厂预制拼装的混凝土基础采用角钢连接在一起，后两者之间浇筑泡沫混凝土，形成一种整体结构，后做防水层。本发明采用柔性钢波纹板和刚性混凝土结构能够改善钢波纹板桥涵对受力的要求，提高结构的整体承载力，解决高填方、大跨径钢波纹板厚度因加工工艺无法达到而引起结构不稳定问题，且标准化生产，缩短了施工周期，减少了水泥、砂石的开采，有利于环保。
