[0033] Specifically, the friction damping sensing unit 1 can include a friction damping ball 11 and a friction damping ball sensor 12. The friction damping sensing unit 1 can be in a ring structure, and the static pressure pile is arranged in the hollow part. The inner wall of the friction damping sensing unit 1 is provided with a plurality of damping balls to contact the static pressure pile.

[0034] When the front end of the static pressure pile contacts the ground or the underground layer, the friction damping ball starts to contact the surface of the soil or other materials. As the pile body continues to move downward, the friction damping ball starts to rotate due to the friction between the friction damping ball and the ground. The friction damping ball sensor (installed near the friction damping ball) detects the rotation of the friction damping ball and records the frequency, the number of turns and other parameters, and sends these data to the central processing unit 3 for processing.

[0035] The depth of the static pressure pile pressed into the ground and the number of the static pressure pile can be calculated according to the diameter of the friction damping ball and the number of turns using the formula distance = number of turns x circumference.

[0036] The pile buried in the ground is usually tens of meters to hundreds of meters, which is welded together section by section. The number of piles is determined by the number of piles used and the burial depth, and the number of welding times can also be determined. In the embodiment, the number of piles can be calculated according to the length of the static pressure pile and the burial depth. For example, if the burial depth is recorded as 100 meters and the length of one pile is 10 meters, it can be determined that there are 10 piles.

[0037] In the embodiment, the total depth of the static pressure pile pressed into the ground is calculated according to the friction damping sensing unit 1, and the laser coding device 2 is controlled to code on the pile according to the preset distance. For example, if the depth of the static pressure pile pressed into the ground calculated by the friction damping sensing unit 1 is 10 meters, the laser coding device 2 can be controlled to code on the static pressure pile every 2 meters.

[0038] The embodiment further includes a recorder, wherein the recorder is connected with the laser coding device 2 and is used for recording the coding times of the laser coding device 2.
