Cement-soil composite pile construction method

The invention discloses a cement-soil composite pile construction method, relates to the field of cement-soil composite pile construction, and comprises construction equipment and a construction method based on a long spiral drilling machine. The construction equipment based on the long spiral drilling machine comprises a drilling rod, a conical collecting barrel which is arranged on the outer side of the drilling rod and can be opened and closed, a chute located on the outer side of the conical collecting barrel and stirring equipment used for stirring slurry. The problems that existing recharge method mechanical equipment is various and complex, a stirring method is difficult in footage and uneven in stirring are solved, the number of the mechanical equipment is small, the stirring uniformity is good, the mechanical equipment is closely connected with one another, the cement-soil stirring pile (M pile) with uniform quality is formed through recharge method construction achieved through the method, the mecha
