Bridge rotation supporting foot force measuring device and supporting foot self-testing balance weight control system and method
The invention relates to a bridge rotation supporting leg force measuring device and a supporting leg self-measuring counterweight control system and method. An existing swivel construction weighing method has defects in construction of a large-tonnage asymmetric bridge swivel structure. The system comprises a supporting leg force measuring device, a supporting leg and a spherical hinge, the spherical hinge is located between the swivel structure and the pier top or the top face of the bearing platform lower rotary table. The supporting foot is located between the swivel structure and the pier top or the top face of the bearing platform lower rotary table and located on the periphery of the spherical hinge, and the supporting foot force measuring device is located at the bottom of the supporting foot. According to the invention, a large-tonnage jack is prevented from being installed between the upper and lower rotating discs to carry out a weighing test during construction of a large-tonnage asymmetric swivel structure, continuous operation of weighing and counterweight is realized, and the supporting counter force of the supporting legs can be monitored during counterweight, so that the gravity eccentric distance change of the swivel structure is mastered, and the counterweight is ensured to have relatively high precision; the supporting foot can be in contact with a pier top slide way during weighing, counterweight and rotation construction of the rotation structure, the actual supporting counter force of the supporting foot can be monitored, and the safety of bridge rotation construction is guaranteed.
本发明涉及一种桥梁转体撑脚测力装置、撑脚自测配重控制系统及方法。现有转体施工称重方法在大吨位非对称桥梁转体结构施工中存在缺陷。本系统包括撑脚测力装置、撑脚和球铰；球铰位于转体结构与桥墩墩顶或承台下转台顶面之间；撑脚位于转体结构与桥墩墩顶或承台下转台顶面之间并位于球铰的外周，撑脚测力装置位于撑脚的底部。本发明避免大吨位非对称转体结构施工时在上下转盘之间安装大吨位千斤顶进行称重试验，实现了称重、配重连续进行的持续操作，配重时可监测撑脚支承反力，从而掌握转体结构的重力偏心距变化，保证平衡配重具有较高精度；转体结构称重、配重及转体施工时撑脚可与墩顶滑道接触，可监测撑脚实际支承反力，保证桥梁转体施工的安全。
