[0016] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0017] Example 1

[0018] like Figure 1-3As shown, a deformation monitoring observation pier includes a base 1 and a support 2. Both the base 1 and the support 2 are made of a steel cage 4 cast in concrete. The steel cage 4 is made of a plurality of horizontal bars and a plurality of vertical bars welded in a crisscross pattern. The bottom of the vertical bars is vertically bent and a hook is provided at the end. The base 1 is buried underground with a height of 1000 mm. The support 2 is located directly above the base 1 and the center lines of the two are coaxial. The height of the support 2 is 1200 mm. A forced centering plate 6 is provided horizontally at the top center of the support 2. A power supply box 7 is provided on the side wall of the support 2 to supply power to the observation equipment. A battery 9 is provided on one side of the base 1 to supply power to the power supply box 7. A base 3 is provided at the lower part of the base 1. The height of the base 3 is 150 mm. The shape of the base 3 is the same as that of the base 1 and the cross-sectional area of ​​the base 3 is larger than that of the base 1. The cross-sectional area of ​​the base 1 is larger than that of the support 2. The cross-sectional area of ​​the base 1 is circular or rectangular, and the cross-sectional area of ​​the support 2 is circular. This structure effectively enhances the structural stability of the observation pier and maintains the internal stress balance of the observation pier, preventing problems such as horizontal displacement, vertical settlement, deformation, etc. after long-term use, thereby ensuring the reliability and accuracy of the monitoring data.

[0019] Furthermore, the support 2 is formed by pouring concrete using a PVC sleeve, which is easy to transport and has low cost. A support leg 5 is provided at the bottom of the sleeve to facilitate the discharge of concrete.

[0020] A connecting plate 10 is embedded in the side wall of the support 2, and a hook 11 is welded on the connecting plate 10, and the power supply box 7 is hung with the support 2 through the hook 11. The power supply box 7 is hung during observation, and can be directly removed after use.

[0021] Furthermore, a foundation pit 8 is dug on the ground on one side of the base 1, a boss 12 is provided on the upper inner wall of the foundation pit 8, a top cover 13 is provided on the top of the foundation pit 8, a flange 14 is provided in the top cover 13 to match the boss 12, the outer wall of the flange 14 is in contact with the boss 12 and the bottom end of the flange 14 extends out of the boss 12, a cable hole 15 is provided on the top cover 13 on the inner side of the flange 14, a gravel layer 16 is laid on the bottom of the foundation pit 8, a heat dissipation bracket 17 is fixed above the gravel layer 16, the heat dissipation bracket 17 is trapezoidal, and the battery 9 is placed above the heat dissipation bracket 17. The foundation pit 8 and the top cover 13 have a protective effect on the battery 9. The heat dissipation bracket 17 and the gravel layer 16 are arranged in the foundation pit 8, which is beneficial to the heat dissipation of the battery 9. The boss 12 is arranged on the upper part of the foundation pit 8, and the top cover 13 is matched with the boss 12 to set the flange 14, which is convenient for the top cover 13 to directly cover and shield the battery 9. The flange 14 and the boss 12 cooperate to have a certain waterproof effect. The flange 14 and the cable hole 15 are located on the outside of the battery 9. Even if a small amount of water penetrates, it will fall along the flange 14 to the side wall of the heat dissipation bracket 17. The heat dissipation bracket 17 is trapezoidal, and the side wall is inclined, which is conducive to water falling directly into the gravel layer 16 and immersing downward, and has a good heat dissipation and waterproof effect as a whole.
