Method for rapidly judging heaving risk of foundation pit stand column
The invention discloses a method for rapidly judging the heaving risk of a foundation pit stand column. The method comprises steps of a telescopic rod, a fixing piece and a laser convergence instrument being installed; adjusting the point position of laser irradiated on a foundation pit support, arranging a connecting piece and a target vertical rod, adjusting the lengths of a telescopic rod and the target vertical rod, ensuring that the laser irradiation point is located at the center point of a target, arranging a plurality of risk prompt areas on the target, and arranging a measuring point for monitoring settlement of the foundation pit support right above the center point of the target; the change value of the vertical displacement of the measuring point being calculated, and the influence of foundation pit support heaving on the target being eliminated by adjusting the length of the vertical rod of the target; and the heaving risk of the stand column being directly judged through a risk prompt area where an irradiation point of the laser convergence instrument on the target is located. According to the method, the influence of foundation pit support heaving on the result is eliminated, the risk degree of foundation pit support heaving can be rapidly identified only by identifying the area where the irradiation point of the laser convergence instrument on the target is located, efficiency is improved, the workload is reduced, cost is low, and adaptability is high.
本发明公开了一种基坑立柱隆沉风险快速判别方法，包括：安装伸缩杆、固定件和激光收敛仪；调节激光照射在基坑围护上的点位，设置连接件和标靶竖杆，调节伸缩杆和标靶竖杆长度，确保激光照射点位于标靶中心点，所述标靶上设置若干风险提示区域，所述标靶中心点正上方设置有用于监测基坑围护沉降的测点；计算测点竖向位移的变化值，通过调节标靶竖杆长度，消除标靶处基坑围护隆沉对标靶的影响；通过激光收敛仪在标靶上的照射点所处的风险提示区域直接判定立柱隆沉风险。该方法消除了基坑围护隆沉对结果的影响，仅需识别激光收敛仪在标靶上的照射点所在区域即可快速识别基坑围护隆沉的风险程度，提高了效率并降低工作量，成本低、适应性强。
