[0002] With the continuous improvement of road construction and the increase in the number of private cars, the safety of road traffic is of particular concern nowadays. A large part of the traffic safety problems come from the road conditions themselves, among which the settlement of the roadbed affects the road conditions of the road surface. When the roadbed settles, the road surface will collapse, tilt or sag. The occurrence of such situations is the main factor in the occurrence of road traffic accidents. Therefore, the road safety inspection department will monitor and survey the roads from time to time. However, the monitoring device currently used for road subgrade settlement does not have a warning function, which is not convenient for staff to intuitively observe the settlement of the roadbed, and the cost and location are easily affected by the environment.

[0022] A spring 12 is provided in the indicator 7, and an indicator sheet 14 is provided on the upper side of the spring 12. The indicator sheet 14 faces the indicator window 16. There is a hole in the middle of the indicator sheet 14, and a pull wire 8 passes through the hole. A positioning sheet 13 is fixed on the pull wire 8. The pull wire 8 passes through a guide tube 9, and the guide tube 9 is buried in the roadbed. The lower end of the pull wire 8 is fixedly connected to a pressure ball 11, which is a lightweight hollow sphere supported and positioned by the roadbed. The positioning sheet 13 is composed of a bolt and a screw sleeve, and the pull wire 8 passes through the screw sleeve to fix the pull wire 8. A guide ring 10 is provided on the inner side of the lower part of the central tube 1 to guide the pull wire 8.

[0023] The working principle of the utility model is: when in use, the pressure ball 11 and the guide tube 9 are buried in the roadbed, there is no connection between the guide tube 9 and the pressure ball, the top cover 2 is arranged horizontally, and is buried around the central tube 1, the pull wire 8 passes through the indicator 7, the pull wire 8 passes through the indicator sheet 14 and the screw sleeve, the pull wire 8 is tightened, and the pull wire 8 is fixed by bolts, so that the spring 12 is in a compressed state, the pull wire 8 is tightened, and the indicator sheet 14 is located in the middle and upper part of the indicator window 16 to complete the layout.

[0024] When the roadbed tilts as a whole, the position of the weight 4 changes, thereby changing the angle of the pressure plate 3, and then pressing the switch 5 to turn on the power, and the indicator light 6 on the corresponding side lights up, indicating that the roadbed tilts to that side.

[0025] When the local roadbed settles, the pressure ball 11 buried inside moves down with the roadbed, and then pulls the pull wire 8, and then drives the indicator sheet 14 to move down, which is indicated on the indicator window 16, and the monitoring is completed.
