Background technique

Since the 1980s, especially in the 21st century, the rapid economic development has increased the urban population, resulting in a shortage of resources. In order to cope with this trend, multi-storey and high-rise buildings have sprung up, so that these buildings can reach the design bearing capacity, and piling under the foundation has emerged as the times require. However, the deviation of the construction personnel during the construction of the line and the position of the pile, the complex geological conditions, and improper construction will all cause the pile body to tilt, the pile to float or the pile length to be buried insufficiently. Pile sinking engineering diseases often cause a reduction in bearing capacity, which adversely affects the safety and normal use of buildings.

However, the existing evaluation of the pile body often judges whether the pile is good or bad by inspecting the integrity of the pile body and the load-bearing performance of the pile in the quality of the pile. The verticality of the pile body belongs to the content of on-site control, and construction personnel often tend to ignore the subsequent changes after the pile body is successfully inserted into the soil. At the construction site, due to the soil squeezing effect during the piling process, the vertical piles will tilt unknowingly, but it cannot be detected in the final inspection. When the earthwork is excavated, the pile body is suddenly found to be tilted. At this time, a series of measures are taken. Remedial measures often result in significant losses.
