Abstract
The utility model relates to a displacement monitoring device, which comprises a non-return valve, a pressure strain gauge, a data processor, and a program data computer. A connecting flexible pipe is connected between the non-return valve and the pressure strain gauge. Liquids are filled inside the connecting flexible pipe. The pressure strain gauge and the data processor are connected through a signal transmission line. The data processor and the program data computer are also connected through a signal transmission line. The displacement monitoring device which can monitor the displacement states of top boards and bottom boards in a real-time manner can further analyze the monitoring data of each tested spot through the program data computer and release an early warning for a large-area landslide accident so as to make workers leave a working site in time or make relevant people take corresponding technical measures. In this way, the adverse influence of the accident can be reduced to the lowest. Even when there is a landslide, the area and the range of the landslide can be known by the monitoring data. Relevant measures such as rescue effort organization can be rapidly adopted.
