Soil squeezing stress diffusion structure

Pile foundations are arranged on a foundation at intervals, soil squeezing stress diffusion holes avoiding pile positions are drilled in the range of the pile foundations, the hole diameter of each soil squeezing stress diffusion hole is 400 mm, the depth of each soil squeezing stress diffusion hole corresponds to one half of the length of a pile, and the soil squeezing stress diffusion holes arefilled with sand. The pile is driven into the pile foundation, the pile extrudes soil of the foundation, so that the pile is smoothly buried into the foundation, and the soil below the pile foundationis extruded outwards due to the fact that the pile continuously extrudes the soil in the process of driving into the foundation. The soil below the pile foundation is extruded outwards to enter the soil extrusion stress diffusion holes, so that the extrusion force is relieved, the existing buildings, municipal pipe networks, railways and bridges cannot be damaged, meanwhile, the base can be prevented from being raised due
