Description of the invention (3) At the end, a plurality of agitating members extend out of the rotating shaft, and at least one nozzle is used to spray the solidified fluid. The agitating members are constructed on the rotating shaft, and the agitating members are separated from the adjacent agitating members in the axial direction of the rotating shaft. The sleeve is constructed with at least one curved inner wall having a radius of curvature slightly larger than the radius of the spiral of the agitating member so as to loosely surround the agitating member. The improved ground pile is built in the foundation by the following method using the soil control machine. Before the rotating shaft is inserted into the foundation, a first agitating mechanism is surrounded by the casing. The rotating shaft is then inserted into the foundation until the rotating shaft moves down along the guide rail at a first controlled excavation speed, while the rotating shaft rotates to control a hole to a first depth, and the casing moves downward at the same speed as the first speed Move to keep the first agitating member in the casing. Thereafter, only the sleeve moves upward on the guide rail, while the rotating shaft remains at the first depth in the hole, so that the sleeve surrounds the second stirring member above the first stimulating member. The shaft is further inserted into the foundation at a second digging speed until the shaft moves down the guide rail, and the shaft rotates to dig the hole to a second depth, and the casing moves at the same speed as the second digging speed, Keep the second spiral wrapped in the casing. When digging a hole to a depth greater than the second depth, the above insertion step of the shaft can be repeated. Finally, the shaft withdraws from the bottom of the hole to obtain an improved pile in the foundation. In the past, there was a problem that during the step of inserting the shaft into the foundation, the shaft of the excavator was accidentally exposed to pressure between the excavating member mounted on its bottom end and an obstacle such as hard rock Inserted in an undesired direction, it is impossible to build an improved ground to extend along the predetermined path in the foundation. However, in the method of the present invention, during the insertion of the shaft, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) (please read the precautions on the back before filling this page). Order A! A7 317587 B7____ 5. In the description of the invention (4), even if the rotating shaft accidentally encounters an obstacle in the foundation, the casing moves downward along the guide rail and surrounds the stirring member at the same time, so the rotation shaft can be prevented from deviating and the shaft can be inserted into the foundation The rotation axis does not deviate from the predetermined path. As a result, an improved ground pile on a predetermined path in the foundation can be accurately constructed. In a preferred embodiment of the present invention, after the step of inserting the rotating shaft, the rotating shaft is moved out of the bottom of the hole according to the following method. That is, the shaft exits at a first exit speed. From the second depth to a third depth, the shaft rotates, and the sleeve moves upward at the same speed as the first exit speed to keep the second agitating member in the sleeve Inside. Then, only the sleeve moves down the guide rail, and the rotation shaft does not move away from the third depth, so that the sleeve surrounds one of the third stirring members above the second stirring member. The shaft exits the hole from the third depth at a second exit speed, while the shaft rotates, and the sleeve moves upward at the same speed as the second exit speed to keep the third agitating member in the sleeve. When the shaft moves out of a hole with a depth greater than the second depth, the above exit steps can be repeated. Moreover, during at least one of the steps of inserting and withdrawing of the rotating shaft, the nozzle of the rotating shaft sprays the solidified fluid into the hole to perform on-site mixing and agitate the solidified fluid and the controlled excavated soil into the hole. When the earth control machine has a single rotating shaft, the sleeve should be made cylindrical with a radius of the spiral of the agitating member with a slightly larger inner radius. When the earth control machine has at least two rotating shafts extending parallel to each other, the casing is preferably constructed with a pair of curved inner walls having a radius of curvature slightly larger than the radius of the spiral of the agitating member.
