Construction method of cement-soil continuous wall and mixed slurrying system

A construction method of a cement-soil continuous wall comprises the following steps that firstly, a guide wall is manufactured, specifically, according to a control point and a control axis, the center line of the guide wall is measured and placed, and guide wall construction is conducted; step 2, measuring and positioning: measuring and placing the position of each section of wall body according to the control points and the control axes, and marking positioning lines on two sides of the wall width on the guide wall; thirdly, wall forming groove sections are excavated, wherein a hydraulic grab bucket is adopted for excavation at intervals to form walls, and the adjacent units are in lap joint to form the walls; 4, cement-soil slurry is prepared outside the holes, specifically, slurry and cement slurry are mixed and stirred into the cement-soil slurry through a mixed slurry making system; fifthly, cement soil slurry is poured, specifically, a wall bottom pouring mode is adopted, and the cement soil slurry is
