[0018] See also Figure 1 and Figure 2 The static pile monitoring device of the embodiment of the present invention includes: a friction damping sensor unit 1, a laser coder 2 and a central processing unit 3; wherein the friction damping sensor unit 1 is penetrated by the static pile 4 to be tested and connected to the static pile 4 to be tested, and is used to record the frequency and number of rotations of the friction damping ball when the front end of the static pile 4 to be tested contacts the friction damping ball; the central processing unit 3 is connected to the friction damping sensor unit 1, and is used to receive the rotation frequency and number of rotations data sent by the friction damping sensor unit 1, and calculate the depth of the static pile pressed into the ground according to the rotation frequency and number of rotations; the central processing unit 3 is also connected to the laser coder 2, and is used to control the laser coder 2 to perform laser coding on the static pile 4 to be tested according to a preset distance.

[0019] Specifically, the friction damping sensor unit 1 may include a friction damping ball 11 and a friction damping ball sensor 12. The friction damping sensor unit 1 may be an annular structure, the static pressure pile is inserted into the hollow part thereof, and a plurality of damping balls are arranged on the inner wall of the friction sensor unit 1 to contact the static pressure pile.

[0020] When the front end of the static pressure pile contacts the ground or underground layer, the friction damping ball begins to contact the surface of the soil or other materials. As the pile body continues to move downward, the friction damping ball will begin to rotate due to the friction between it and the ground; the friction damping ball sensor (installed near the friction damping ball) will detect the rotation of the friction damping ball, and record the rotation frequency, number of revolutions and other parameters, and send these data to the central processor 3 for processing.

[0021] According to the diameter of the friction damping ball and the number of rotations, the formula distance = number of rotations × circumference can be used to calculate the depth to which the static pressure pile has been pressed into the ground and the number of static pressure piles.

[0022] The buried piles are usually tens to hundreds of meters long and are welded together one by one. The number of piles is determined by looking at the number of piles used, the buried depth, and the number of welding times. In this embodiment, the number of piles can be calculated based on the length and buried depth of the static pressure pile. For example, if the buried depth is recorded as 100 meters and each pile is 10 meters, 10 piles can be determined.

[0023] In this embodiment, the total depth of the static pile is calculated according to the friction damping sensor unit 1, and then the laser coder 2 is controlled to code the pile body according to the preset distance. For example, if the depth of the static pile calculated by the friction damping sensor unit 1 is 10 meters, the laser coder 2 can be controlled to code the static pile every 2 meters.

[0024] This embodiment also includes: a recorder; wherein the recorder is connected to the laser coder 2 and is used to record the number of times the laser coder 2 codes.

[0025] It can be obviously concluded from the above that the static pressure pile monitoring device provided in this embodiment, by connecting the friction damping sensor unit to the static pressure pile, uses the frequency and number of rotations of the friction damping ball to measure the depth of the static pressure pile pressed into the ground; and then uses a laser coder to code once every preset distance, so that the static pressure pile can be physically marked, so that construction personnel and subsequent inspections can intuitively see the sinking progress of the pile body; it can be used to verify whether the data provided by the sensor is accurate; through the automated coding process, the need for manual operation is reduced, the construction efficiency is improved and the possibility of human error is reduced.
