Abstract
The invention discloses a simple device for horizontal displacement monitoring. The simple device comprises a plurality of electricity measuring piles, resistance wires arranged between every two adjacent electricity measuring piles, and ohmmeters used for measuring resistance values between every two adjacent electricity measuring piles. The electricity measuring piles are steel members coated with insulation varnish and capable of conducting electricity, the electricity measuring piles are arranged on edges of foundation pits or side slopes, and the straight lines where two electricity measuring piles are located are perpendicular to the edges of the foundation pits or the side slopes. The two ends of the resistance wires are electrically connected with every two adjacent electricity measuring piles respectively, the resistance wires between the two electricity measuring piles are in a tightening state and can be stretched out when the distance between the two adjacent electricity measuring piles is increased. In the testing and using process, the simple device is high in testing speed and does not need to be specifically arranged on target positions on the side slopes; meanwhile, the simple device has the advantages of being simple in structure, convenient to use and low in cost, and large testing equipment is not needed.
