Description

technical field [0001] The invention relates to a device for lateral reinforcement and restoration of polluted soil. Background technique [0002] Concrete piles are widely used in today's engineering field. Due to the characteristics of the cast-in-situ pile construction technology, the retaining wall mud reduces the lateral friction between the soil layer and the pile body, which affects the bearing performance of the pile foundation after the pile is formed. In actual engineering, grouting pipes are generally set through steel cages, and secondary grouting is performed when the pile body concrete is close to solid to fill the mud skin between the cast-in-place pile and the pile hole. However, due to the difference and influence of geological conditions, the improvement of the vertical bearing capacity of the pile foundation by this measure may have limited effect. It is necessary to develop a new type of pile foundation that is suitable for geological conditions with po...
