[0002] Cement Mixing Pile is a foundation treatment technology, mainly used for reinforcing soft soil foundation, improving foundation bearing capacity, reducing settlement and preventing foundation liquefaction, etc. It forms mixed soil by mixing cement and other curing agents with foundation soil, thereby improving the strength and stability of foundation soil. Cement mixing pile is a mature foundation treatment technology. Through reasonable design and construction, it can effectively improve the engineering properties of foundation soil and improve the safety and service life of buildings. Therefore, it is widely used in treating soft foundation soil or coastal soft soil. With the continuous improvement of national water system planning, a large number of new construction and repair of seawalls and river embankment facilities, cement mixing pile construction technology has been more and more widely used.
