Balance weight method in bridge swivel construction process and bridge swivel construction method
The invention relates to a weight balancing method in a bridge swivel construction process and a bridge swivel construction method, and the method comprises the steps: (1) arranging a beam body restraint device below a beam body, the beam body restraint device being provided with a force measuring module used for detecting a beam body acting force borne by the beam body restraint device; (2) calculating a theoretical unbalance moment MC of the swivel structure and a theoretical balance weight T0 of swivel structure balance; (3) pre-counterweight T1 is carried out on the swivel structure at the counterweight preset position, then temporary locking between the beam body and the swivel pier is removed, and a detection value F1 of the force measurement module is obtained; (4) according to the detection value F1 and the pre-balance weight T1, the actual unbalance moment MG of the swivel structure is solved; and (5) adjusting the weight of the counterweight to T2 to enable the detection value F2 of the force measurement module to be within a set range, thereby completing the counterweight operation. In addition, the invention further relates to a bridge swivel construction method. The beam body does not need to be weighed, convenience and reliability are achieved, and the balance weight precision is high; the operation steps are few, the tedious processes of weighing, weight balancing, re-weighing, re-weight balancing and the like are omitted, and the efficiency of bridge swivel construction is remarkably improved.
本发明涉及一种桥梁转体施工过程中的配重方法以及桥梁转体施工方法，包括：(1)在梁体下方设置梁体约束装置，梁体约束装置配置有用于检测其所受梁体作用力的测力模块；(2)计算转体结构的理论不平衡力矩MC和转体结构平衡的理论配重T0；(3)在配重预设位置处对转体结构进行预配重T1，随后拆除梁体与转体墩之间的临时锁定，获取测力模块的检测值F1；(4)根据检测值F1、预配重T1，求出转体结构的实际不平衡力矩MG；(5)调整配重重量至T2，使测力模块的检测值F2在设定范围内，即完成配重操作。另外还涉及一种桥梁转体施工方法。本发明无需对梁体进行称重作业，方便可靠，配重精度高；作业步骤较少，省去了称重‑配重‑再称重‑再配重…的繁琐流程，显著地提高桥梁转体施工的效率。
