Array type concrete servo supporting device and regulation and control method
The invention belongs to the field of foundation pit engineering construction supporting, and provides an array type concrete servo supporting device and a regulation and control method. The array type concrete servo supporting device comprises a multi-point synchronous bearing jack array, a high-precision servo feedback controller, a distributed cloud computing center, a short sound wave displacement sensor, a load balance plate, a threaded transmission rod, a power driver, a high-torque speed reduction device and a high-strength corrosion-resistant protective shell, and an MPC model prediction control method is adopted as a regulation and control method. A foundation pit excavation model is established, and a control strategy is calculated using the current state and predictions within a period of time in the future. According to the array type concrete servo supporting device, multi-point synchronous bearing is adopted, and a plurality of jacks are arranged on a single support and can be independently adjusted, so that the axial force of the support is more accurately and flexibly adjusted; meanwhile, the regulation and control method can predict the future state of the enclosure structure and continuously correct and predict according to the current state, so that the foundation pit construction risk is reduced.
本发明属于基坑工程施工支护领域，提供了一种阵列式混凝土伺服支撑装置及调控方法。阵列式混凝土伺服支撑装置包括多点同步承载千斤顶阵列，高精度伺服反馈控制器，分布式云计算中心，短声波位移传感器，载荷平衡板，螺纹传动杆，动力驱动器，高扭矩降速装置，高强度耐腐蚀保护外壳，调控方法采用MPC模型预测控制方法，建立基坑开挖模型，使用当前状态和未来一段时间内的预测来计算控制策略。阵列式混凝土伺服支撑装置采用多点同步承载，在单根支撑上布置多个千斤顶，均可独立调节，从而对支撑轴力进行更加精确、灵活的调整；同时，调控方法能够预测围护结构未来状态，并根据当前状态不断修正预测，降低基坑施工风险。
