Hollow pile with multiple holes on lateral wall

Abstract

The invention provides a hollow pile with multiple holes on a lateral wall, belonging to a novel hollow pile for civil engineering. With the adoption of the hollow pile with multiple holes on the lateral wall, soil drainage and solidification can be accelerated, the bearing capacity of a pile body is improved, namely punched holes 4 are formed between an internal wall 2 and an external wall 1 of the pile body of the traditional hollow pile, and upper rows of holes and lower rows of holes are arranged in a staggered manner to form a honeycomb shape. Compared with the traditional hollow pile with the same section size, the holes are formed on the lateral wall and are arranged in a staggered manner and in a honeycomb shape, so that the pile body has a function of transverse water permeability, the dissipation rate of excess pore-water pressure in a foundation soil body can be accelerated, and the efficiency of foundation drainage and solidification is greatly improved; moreover, after pile sinking is completed, soil body extruded from the holes of the pile body is compacted and solidified with a surrounding soil body, the influence of a water film on a critical face between the pile and soil on the side friction resistance of the pile can be effectively reduced, the bearing capacity of the pile body is improved, building garbage is reduced, the environment is protected, and social resources are saved.

Description

technical field [0001] The invention relates to a hollow pile with porous side walls, which belongs to the field of civil engineering. Background technique [0002] As a foundation treatment method, the pile foundation has a good effect on controlling the foundation settlement and settlement velocity in deep soft soil areas and reducing the foundation vibration caused by the upper load. In the process of foundation reinforcement, the structural properties of the pile itself are used to strengthen the foundation, and the soil itself, as a soft soil foundation, does not fully play its role in the true sense. For example, the foundation is consolidated by discharging pore water in the soil, Enhance foundation strength. [0003] In addition, the outer wall of the traditional hollow pile is relatively smooth. Under the action of hydrostatic pressure, the pore water seeping out of the soil around the pile can easily form a "water film" on the critical surface of the pile and soil...
