In order to study the application effect of bidirectional cement mixing pile construction technology in municipal engineering technology in soft soil foundation reinforcement,this paper analyzes the example of the set-ting of construction process parameters and its influence on the effect of foundation reinforcement.Through de-tailed construction steps and site settlement monitoring,it is pointed out that reasonable slurry configuration and precise pile position calibration are the key factors to ensure the uniformity of pile body and foundation stabil-ity.At the same time,the settlement monitoring data shows that the foundation reinforced by bidirectional cement mixing pile is basically stable after 112 days,and the maximum settlement value is 43.2 mm,50 cm below the design standard;The maximum horizontal and vertical displacement are 0.06 mm and 0.22 mm respectively,both within the al-lowable range.It shows that the technology has a significant effect in improving the bearing capacity of the foun-dation and reducing the settlement.
