[0030] As shown in Figs. 1-2 The control reinforcement cover adjusting device provided by the embodiment measures the distance of the pouring formwork from the pouring of the pier body 100. The pouring formwork 300 is arranged on the peripheral edge of the pier body. In the embodiment, the control reinforcement cover adjusting device comprises a clamping and fixing device 1 sleeved on the outermost longitudinal reinforcement 200 of the pier body 100, a measuring device 2 connected to one end of the clamping and fixing device 1, and a scale device 3 arranged at the other end of the measuring device 2.

[0031] In the embodiment, in order to facilitate the reliable fixation of the clamping and fixing device 1, the clamping and fixing device 1 comprises a clamping disc 11, a circular hollow part opened on the clamping disc 11, a plurality of telescopic cylinders 13 arranged in a circular array on the clamping disc 11 and towards the center of the circular hollow part, a top block 12 placed in the circular hollow part and connected to the telescopic cylinders 13 one by one, and an anti-skid rubber 14 arranged on the inner side of the top block 12 and close to the center of the circular hollow part. The top block 12 is in an arc shape.

The telescopic rod 23 is engraved with a scale, and the scale reading is convenient for controlling the thickness of the protective layer. According to the position of the pouring formwork 300, the telescopic rod 23 is pulled out, and the position of the pouring formwork 300 is determined by using the infrared rays emitted by the infrared markers 32. The thickness of the protective layer can be accurately controlled by the measuring device 2 and the distance measuring device 3, and the thickness variation caused by the vibration of the formwork is prevented.
