The lifting drive component 120 is a cylinder and is connected to the grouting pipe positioning part 200.

[0026] The grouting pipe positioning part 200 includes a base plate 210 connected to the lifting drive 120 and a positioning sleeve 220 detachably mounted on the base plate 210.

[0027] The positioning sleeve 220 is detachably installed on the base plate 210, and the base plate 210 is connected to the piston ends of the lifting drive 120 on both sides of the mounting base 110. The mounting base 110 is installed at the lower end of the pile driver's mast. When in use, the pile driver's mast is perpendicular to the ground. The base plate 210 is positioned and pressed on the ground by the telescopic end of the lifting drive 120, so that the positioning sleeve 220 is located above the borehole. When the grouting pipe is put into the borehole, the grouting pipe is positioned by passing through the positioning sleeve 220. This can effectively prevent the grouting pipe from shifting when it is put into the borehole, and it is convenient to connect and install with the pile driver's mast, making it easy to disassemble and install.
