The split machine construction method is to first align the pile frame with the pile point, mix it to the design requirements and then move it away, then move the pile driver over to re-align the pile point and plant the pile to the design requirements, that is, the construction of the pile point is completed; this construction method has the following defects:
[0003] 1. After mixing, the pile point is destroyed by moving away, and it is difficult for the pile driver to re-position the pile point;
[0004] 2. Two devices are required for construction, which is costly;
[0005] 3. It occupies a large area; 4. It requires many operators.
[0006] The existing integrated machine construction usually uses the mixing and piling integrated machine to perform translational construction. Specifically, the integrated machine construction method is the mixing and piling integrated machine construction. First, the mixing station is aligned with the pile point. After mixing to the design requirements, the piling station (pile pressing platform) is translated to the pile point (mixing station). The pile is planted to the design requirements, and the construction of the pile point is completed. The existing equipment of this construction method has the following defects:

[0038] The mobile mixing and piling machine is used to align the mixing drill head with the first pile driving point, and the power head winch and the mixing power head are started. After the mixing power head mixes to the preset depth, it is lifted up to the original position;
[0039] Start the first pile driving platform, its pile clamp box clamps the precast pile, and the precast pile is implanted into the first mixing pile under the action of its pile driving cylinder; at the same time, rotate the mixing power head to the second pile driving pile point, start the power head winch and mixing power head again, and after the mixing power head stirs to the preset depth, lift it up to the original position;

[0100] S12, start the mast hoist 55, and retract the steel wire rope 54 onto its drum, so that the distance between the movable pulley block 57 and the fixed pulley block 56 is gradually shortened. At the same time, the mast hoist 55 is driven to rotate by the vertical frame pull rope 52 until it rotates to a preset angle and then stops. The other end of the telescopic diagonal support rod assembly 51 is connected to the first connection position on the fuselage platform 1. The diagonal support oil cylinder 512 on the telescopic diagonal support rod assembly 51 lifts the column assembly 4 until it is perpendicular to the fuselage platform 1, and the mast is erected.

[0104] The first pile driving platform 2 is started, and its pile clamping box 22 clamps the precast pile, and the precast pile is implanted into the first mixing pile under the action of its pile driving cylinder 24; at the same time, the mixing power head 41 is rotated to the second pile driving point B, and the power head winch 45 and the mixing power head 41 are started again, and the mixing power head 41 rotates and drills downward at the same time.

[0107] First, the other end of the telescopic diagonal brace assembly 51 is disconnected from the first connection position on the fuselage platform 1, and then the rotary drive device 6 is started to drive the column section 43 to rotate so that the stirring power head 41 arranged thereon rotates to the second pile driving point B, and then the other end of the telescopic diagonal brace assembly 51 is connected to the second connection position on the fuselage platform 1;
[0108] In the present invention, the mixing and piling integrated machine can be used to alternately mix and plant piles at two pile driving positions (while the first pile driving position A is being planted, the mixing power head 41 on the column assembly 4 can be rotated to the second pile driving position B to perform mixing operations thereon), thereby improving construction efficiency; at the same time, since the rotation of the column assembly 4 can drive the mixing power head 41 to rotate, the two pressing platforms are symmetrically arranged about the rotation center C of the column assembly 4, so that the mixing center and the pile driving platform pile planting center coincide with each other, thereby reducing the difficulty of piling and improving the concentricity of the two pile positions.
[0109] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
