Device and method for monitoring upheaval of soil body at bottom of foundation pit
The invention relates to the technical field of foundation pit deformation monitoring, in particular to a foundation pit bottom soil upheaval monitoring device and method.The foundation pit bottom soil upheaval monitoring device comprises a balancing weight and an anchor rod which is buried under the ground of a foundation pit bottom and connected with the balancing weight and serves as a support, the lower portion of the anchor rod is driven into bed rock, and a monitoring device body is embedded in the balancing weight; the monitoring device body comprises at least one capacitance monitoring assembly arranged in the vertical direction; the capacitance monitoring assembly is provided with two fixed pole pieces which are vertically arranged and a monitoring rod, one end of the monitoring rod is vertically provided with a mica sheet, the other end of the monitoring rod extends out of the balancing weight to move up and down along with the soil body, and the mica sheet enters between the two fixed pole pieces to change capacitance so as to monitor the movement amount of the soil body under the driving of the monitoring rod; according to the invention, the foundation construction is not influenced, and real-time measurement, real-time feedback and accurate measurement can be realized.
本发明涉及基坑变形监测技术领域，特别涉及一种基坑坑底土体隆起的监测装置及方法，包括埋设于基坑坑底地面以下，包括配重块以及与其连接并作为支撑的锚杆，所述锚杆下部打入基岩中，所述配重块内嵌监测装置本体，所述监测装置本体包括竖直方向上设置的至少一个电容监测组件；所述电容监测组件具有竖直布置的两定极片和监测杆，所述监测杆一端竖直设有云母片，另一端伸出所述配重块跟随土体上下运动，通过所述监测杆的带动，所述云母片进入两所述定极片之间改变电容以监测土体移动量；本发明能够实现不影响基础施工、实时测量、实时反馈以及精准测量。
