Bidirectional waving hollow concrete filled steel tube pier and construction process thereof
The invention relates to a bidirectional wave-starting hollow concrete-filled steel tube pier and a construction process thereof. The pier comprises an outer-layer wave-starting steel tube, interlayer concrete and an inner-layer wave-starting steel tube, the outer-layer wave starting steel pipe is provided with a plurality of outer-layer corrugations in the height direction of the pier, and the inner-layer wave starting steel pipe is provided with a plurality of inner-layer corrugations in the height direction of the pier; the outer corrugations face the outer side of the pier, the inner corrugations face the inner side of the pier, and the outer corrugations and the inner corrugations are staggered in height. The method has the beneficial effects that the outer-layer wave-starting steel pipe and the inner-layer wave-starting steel pipe can be produced on a large scale; the outer-layer wave-starting steel pipe and the inner-layer wave-starting steel pipe can be used as formworks and can effectively resist expansion in the concrete setting process, and the formwork does not need to be disassembled in the whole process; the inner-layer and outer-layer wave starting steel pipes can compensate a part of longitudinal deformation, do not bear vertical loads and only play a role in circumferential constraint, and the bearing capacity of the pier body is good; corrugations are pressed on the inner-layer and outer-layer steel pipes, and the axial stress of the inner-layer and outer-layer corrugation steel pipes under the action of axial pressure or eccentric force is reduced.
本发明涉及一种双向起波中空钢管混凝土桥墩及其施工工艺，包括外层起波钢管、夹层混凝土和内层起波钢管；外层起波钢管沿桥墩高度方向设有数道外层波纹，内层起波钢管沿桥墩高度方向设有数道内层波纹；外层波纹朝向桥墩外侧，内层波纹朝向桥墩内侧，外层波纹和内层波纹高度错开。本发明的有益效果是：外层起波钢管和内层起波钢管能够规模化生产；外层起波钢管和内层起波钢管能够作为模板使用，且能有效抵抗混凝土凝结过程中的膨胀，整个过程无需对支模进行拆模；内外层起波钢管自身能补偿一部分纵向变形，不承受竖向荷载，只发挥环向约束作用，墩身承载能力好；内外层钢管压出波纹，减小内外层起波钢管在轴压或偏心力作用下的轴向应力。
