Pi-shaped beam rear fulcrum hanging basket of ultra-wide variable-width PC cable-stayed bridge and construction method thereof
The invention discloses an ultra-wide and widening PC cable-stayed bridge pi-shaped beam rear fulcrum hanging basket and a construction method thereof.The ultra-wide and widening PC cable-stayed bridge pi-shaped beam rear fulcrum hanging basket comprises a main truss system and a bottom basket system, the bottom basket system is integrally arranged below the main truss system, and the main truss system is connected with the bottom basket system and a pi-shaped beam through an anchoring suspension system; the main truss system comprises a main truss; the middle lower cross beam is arranged below the main truss and is detachably connected with the main truss, a movable cushion block is arranged below the middle lower cross beam, and the middle lower cross beam can linearly move in the width direction of the pi-shaped beam; the rear fulcrum hanging basket further comprises a walking system, and the walking system can drive the main truss to move in the length direction of the pi-shaped beam so that the bottom basket system can linearly move along with the main truss. According to the invention, the position and the size of the counter-force of the supporting point of the hanging basket are adjusted, so that the active control on the stress of the main beam is achieved, and the safety risk during the construction of the ultra-wide main beam of the PC cable-stayed bridge is avoided.
本发明公开了超宽变宽PC斜拉桥π型梁后支点挂篮及其施工方法，超宽变宽PC斜拉桥π型梁后支点挂篮,包括主桁系统以及底篮系统，底篮系统整体设置在主桁系统的下方，主桁系统通过锚固悬吊系统与上述底篮系统、π型梁连接；主桁系统包括主桁架；以及中下横梁，该中下横梁设置在上述主桁架的下方，与上述主桁架可移除连接，在该中下横梁下方设有可移动垫块，中下横梁可沿上述π型梁的宽度方向线性运动；后支点挂篮还包括行走系统，该行走系统可带动上述主桁架沿π型梁的长度方向运动，以使底篮系统随之线性运动。本发明实现了对挂篮支点反力位置以及大小的调节，以达到对主梁受力的主动控制，使其规避了PC斜拉桥超宽主梁施工时的安全风险。
