如图1至图3所示，所述转轴9的顶端连接有可拆卸轴杆1和固定把手5，所述可拆卸轴杆1连接有可拆卸把手2，所述固定把手5上设有将所述固定把手5固定在绝缘安装箱7上的固定螺栓5。
如图1至图3所示，所述报警回路包括电源14和报警装置，所述电源14通过电缆15与所述第一导电金属薄片16连接，所述电源14通过电缆与所述报警装置连接，所述报警装置通过电缆与所述第二导电金属薄片19连接。
如图1至图3所示，如果所述第一导电金属薄片16、第二导电金属薄 片19接触，则所述第一导电金属薄片16、电源14、报警装置、第二导电金属薄片19构成闭合回路。
如图1至图3所示，所述绝缘安装箱7内设有支架13，所述电源14固定在所述支架13上。
如图1至图3所示，所述绝缘安装箱7连接有金属盖板4，所述报警装置包括警报器11和蜂鸣器3，所述警报器11、蜂鸣器3分别设置在所述金属盖板4上，所述警报器11通过电缆12与所述电源14连接，所述蜂鸣器3通过电缆8与所述第二导电金属薄片19连接，所述警报器11通过所述金属盖板4与所述蜂鸣器3连接。
如图1至图3所示，本发明提供的一种地下泥土流失简易警示器，需要事先测量当地土体的抗剪强度，在观测点附近选取相似的地层，采用土工刀和铁锹等工具平整试验土体，并留出足够的工作平面,估计土样的抗剪强度选装合适米字板头21，握住米字板头21，将指针逆时针旋转至0刻度处，保持恒定的垂直压力将米字板头21垂直插入土中一定深度，深度应小于3m,，顺时针以5～10s/周的速率旋转仪器上部把手至土体被剪切破坏，记录下把手转过的角度，土体被剪切破坏后，缓慢释放弹簧扭力。记录下弹簧扭力计10上指针所示读数。通过带入公式即可求出土的抗剪强度。
安装地下泥土流失简易警示器时，先用钻机钻穿表面的混凝土地面和硬土层后,安装好由绝缘材料制成的绝缘安装箱7，估计土样的抗剪强度选装合适米字板头21，握住米字板头21，将指针逆时针旋转至0刻度处，保持恒定的垂直压力，将米字板头21压入土样至一定深度，深度应小于3m，顺时针以5～10s/周的速率旋转仪器上部的可拆卸把手2，转动的角度为使试样发生剪切破坏时所需转动角度的80％，转动到预计的角度后，用固定螺栓5将固定把手6锁紧在绝缘安装箱4上，拆除可拆卸轴杆1和可拆卸把手2，调整支架13的位置，并通过电缆15将电源14与第一导电金属薄片16连接起来，第一导电金属薄片16通过固定螺栓20和第一绝缘支杆171固定于弹簧扭力计10的下部，在第一导电金属薄片16附近安装第二导电金属薄片19，保持第一导电金属薄片16、第二导电金属薄片19的距离为5mm(如图2所示)，并利用第二绝缘支杆172和固定螺栓18将第二导电金属薄片19固定在绝缘安装箱7上，安装金属盖板4并利用电缆12将警报器11与电源14连接，利用电缆8将蜂鸣器3与第二导电金属薄片19连接。
当观测点下部的米字板头21深度处的土壤被地下水冲刷流失后，弹簧扭力计10的下半部分会发生转动，从而使得第一导电金属薄片16与第二 导电金属薄片19相互接触(如图3所示)，电源14、第一导电金属薄片16、第二导电金属薄片19、蜂鸣器3以及警报器11在电缆的连接下形成一条闭合回路，从而实现地陷灾害的预警的目的。
