Intelligent monitoring and balancing method for cantilever casting unbalance loading of hanging basket
The invention discloses an intelligent monitoring and balancing method for cantilever casting unbalance loading of a hanging basket. The method comprises unbalance loading monitoring and unbalance loading balancing. Unbalance loading monitoring: acquiring an allowable maximum stress difference value of two ends of the cantilever, setting a stress early warning threshold value, setting an early warning level, and performing real-time monitoring; and unbalance load balancing: according to a stress difference value obtained through unbalance load real-time monitoring, when the early warning level reaches three levels or above, unbalance load adjustment is carried out in real time, and balance is recovered. According to the method, the stress states of the cantilevers at the two ends are monitored in real time, the safest early-warning threshold value is determined through the three methods, the early-warning level is set, and when the stress monitoring value exceeds the graded early-warning threshold value, the management platform gives an alarm in real time to remind a constructor to deal with the unbalanced torque of the cantilevers at the two ends; a concrete flow adjusting device suitable for symmetrical construction of a cantilever is used in the concrete pouring process, and the stress unbalance state caused by human and bridge construction factors is accurately corrected according to stress data fed back by a software management platform in real time.
本发明公开了一种挂篮悬臂浇筑偏载智能监测及平衡方法，包括偏载监测和偏载平衡；偏载监测：获取悬臂两端允许最大应力差值，设置应力预警阈值，设置预警级别，实时监测；偏载平衡：根据偏载实时监测获得的的应力差值，预警级别达到三级及以上时，实时进行偏载调节，恢复平衡。本发明方法实时监测两端悬臂的应力状态，利用上述三种方法确定最安全的预警阈值，并设置预警级别，当应力监测值超过分级预警阈值时，管理平台实时发出警报提醒施工人员处理两端悬臂的不平衡力矩，在混凝土浇筑过程中使用一种适用于悬臂对称施工的混凝土流量调节装置，根据软件管理平台实时反馈的应力数据，精确修正因人为和桥梁本身构造因素导致的应力不平衡状态。
