[0002] A bored pile is a pile made by directly drilling a hole at the designed pile position. Its cross-section is circular. After the hole is formed, a steel cage is placed in the hole and concrete is poured. Due to the advantages of no vibration, no soil squeezing, low noise, and suitability for use in areas with dense urban buildings, bored piles are widely used in construction. According to different hole-forming processes, bored piles can be divided into bored piles with dry holes, bored piles with mud wall protection, and bored piles with manual holes, etc. They are used in urban buildings. According to their different hole-forming methods, bored piles can be divided into bored piles, sunken pipe bored piles, manually dug bored piles, explosive expansion bored piles, etc. Bored and poured piles refer to piles made by drilling a pile hole with a drilling machine and pouring concrete in the hole (or first hanging a steel cage in the hole). Depending on whether the drill bit of the drilling machine is constructed in the aquifer of the soil, it is divided into three methods: mud wall drilling, dry drilling and casing wall drilling. At present, most of the verticality detection methods and tools used for underwater bored piles after drilling are ultrasonic detection or caliper detection.
