Bridge swivel system and method in extremely asymmetric state
The invention relates to a bridge swivel system and method in an extremely asymmetric state, and mainly aims to solve the problem that swivel balance is difficult to solve by only leaning on a short-span side counterweight due to large unbalanced bending moment of a swivel bridge. Except a swivel center spherical hinge, an auxiliary supporting system is additionally arranged at the bottom of a swivel long arm side beam at a certain distance from the center spherical hinge. The pushing jack and the dragging jack are used for alternately applying force to the auxiliary support to maintain stable rotation of the bridge, and the acting point of the force is approximately free of eccentricity relative to the auxiliary support. The sum of the magnitude of the jacking force and the magnitude of the dragging force remains unchanged in the alternating period. According to the method, the added equipment investment is little, the requirement for field technicians in the operation process is low, and the method can be applied to swivel engineering with large auxiliary supporting stress.
本发明涉及一种极不对称状态下的桥梁转体系统和方法，主要针对转体桥不平衡弯矩较大，仅靠在短跨侧配重难以解决转体平衡的情况。除了转体中心球铰外，在转体长臂侧梁底，距离中心球铰一定距离处增设辅助支撑系统。用顶推千斤顶和拖拉千斤顶交替地对辅助支撑施加力，维持桥梁平稳地转体，力的作用点相对辅助支撑近似无偏心。顶推力和拖拉力在交替期间仍保持力的大小之和不变。本发明增加的设备投入很少，操作过程对现场技术人员要求低，可应用于辅助支撑受力较大的转体工程。
