[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A high fill roadbed settlement deformation monitoring device includes an N-shaped bracket 1, the bracket 1 is made of stainless steel to improve the overall strength and play a certain anti-rust role, the upper end of the bracket 1 is fixedly inserted with a connecting plate 2 to prevent the monitoring plate 3 from tilting, the lower end of the connecting plate 2 is slidably inserted with a monitoring plate 3 to cooperate with a scale to monitor ground settlement deformation, and a scale is fixed on the surface of the monitoring plate 3;

[0022] In this embodiment, the left and right ends of the bracket 1 are both slidably sleeved with second lifting blocks 9, which are used to drive the universal wheels 10 to lift and lower. The inner side wall of the second lifting block 9 is fixedly connected with a guide block 13, which is used to keep the second lifting block 9 lifting and lowering in a straight line. The outer side wall of the bracket 1 is provided with a guide groove corresponding to the guide block 13, and one end of the guide block 13 slides and extends into the guide groove. The lower end of the second lifting block 9 is rotatably connected with two universal wheels 10, which is used to facilitate the movement of the bracket 1. The two universal wheels 10 are respectively located at the front and rear sides of the bracket 1. The upper end of the second lifting block 9 is fixedly connected with a second electric push rod 8, which is used to drive the second lifting block 9 to lift and lower. The second electric push rod 8 is fixedly sleeved with two first fixing rings, which are used to improve the firmness between the second electric push rod 8 and the support block 7. The two first fixing rings are respectively fixed on the upper and lower sides of the support block 7. The upper end of the second electric push rod 8 is fixedly sleeved with a support block 7, which is used to support the second electric push rod 8. One end of the support block 7 is fixed to the outer side wall of the bracket 1.

[0023] In this embodiment, a slide groove is provided at the lower end of the bracket 1 and near the left and right side edges. The inner top of the slide groove is fixedly connected with a first electric push rod 4 for driving the first lifting block 11 to rise and fall.
