Underwater main pier just made of skew bridge crossing skew channel bridge
The invention discloses an in-water main pier for a skew bridge of a skew channel bridge, which comprises pier columns transversely distributed on two sides of the bottom of the bridge, and the pier columns comprise stress main piers with rectangular or circular or ellipse-like cross sections and anti-collision auxiliary piers; the connecting line of the supporting points at the top of the stress main pier is parallel to the normal line of the longitudinal axial face in the length direction of the bridge or coincides with the normal line of the longitudinal axial face in the length direction of the bridge, and the stress main pier and the anti-collision auxiliary pier are each provided with an axial section parallel to the water flow direction. The axial sections of the stress main pier and the anti-collision auxiliary pier pass through the symmetry axis of the cross sections of the stress main pier and the anti-collision auxiliary pier, and when the cross section of the pier column is rectangular or similar to an oval, the axial sections of the pier column are distributed in the long axial direction of the stress main pier and the anti-collision auxiliary pier. The requirement that the longitudinal axial surface in the specific direction of the pier abutment is consistent with the water flow direction is met, forward construction of a large-span skew bridge with piers arranged in water is achieved, multiple problems caused by skew crossing of a planned route and the navigation water flow direction are solved, the construction mode is simple and economical, and adaptability is high.
本发明公开了一种跨斜交航道桥斜桥正做的水中主墩，包括横向分布于桥梁底部两侧的墩柱，墩柱包括横截面为矩形或圆形或类椭圆形的受力主墩和防撞辅墩，受力主墩顶部的支承点的连线平行于沿桥梁长度方向的纵轴面的法线或与沿桥梁长度方向的纵轴面的法线重合，受力主墩和防撞辅墩均具有平行于水流方向的轴截面，受力主墩和防撞辅墩的轴截面经过受力主墩和防撞辅墩横断面的对称轴，墩柱的横截面为长方形或类椭圆形时，墩柱的轴截面沿受力主墩和防撞辅墩的长轴向分布。本发明满足墩台特定方向纵轴面与水流方向一致的要求，实现了使水中设墩的大跨径斜交桥梁斜桥正做，解决了规划线路与通航水流方向斜交带来的多个难题，构造方式简单经济，适应性强。
