These materials can be steel, concrete or other composite materials. Composite piles are usually designed and used to overcome the limitations of single material piles, such as limitations in bearing capacity, bending resistance or corrosion resistance. They can be used in a variety of engineering applications, including buildings, bridges, docks, retaining walls, etc. Common composite pile types include steel tube concrete piles, steel pile concrete piles, reinforced concrete piles, etc. The selection of the appropriate composite pile type depends on specific engineering requirements, geological conditions, structural design and other factors.

The outer wall of the pull rod 17 is slidably connected to the top of the shell 11, the outer wall of the rotating rod 6 is sleeved on the inner wall of the pile barrel 2, the top of the pull rod 17 is fixedly connected with a handle 18, the outer periphery of the limit plate 16 is slidably connected to the inner wall of the shell 11, the outer wall of the latch rod 13 is inserted into the inner wall of the latch hole 10, the left end of the spring 14 is fixedly connected to the bottom of the left inner wall of the shell 11, the right end of the spring 14 is fixedly connected to the left end of the latch rod 13, the outer wall of the positioning rod 9 is slidably connected to the inner wall of the jack 4, and the bottom end of the rotating rod 6 is rotatably connected to the inside of the cone head 3.

When it is embedded in the appropriate position, adjust the position of the latch hole 10, and the latch rod 13 will automatically pop out and insert into the latch hole 10 due to the expansion and contraction of the spring 14. At this time, the platform 1 is locked, and then the rotating rod 6 is rotated by using an electric tool or manually. The rotating rod 6 drives the disc 7 to rotate, and the connecting rods 8 on both sides of the disc 7 will push the positioning rod 9 out of the socket 4 and insert it horizontally into the soil like a tree root, firmly When the combined pile needs to be removed, the rotating rod 6 is first rotated in the opposite direction to retract the positioning rod 9 from the soil, and then the pull rod 17 and the limit plate 16 are driven upward by pulling the handle 18, and the linkage rod 15 is slanted to pull the latch rod 13. When the latch rod 13 is completely disengaged from the latch hole 10, the pile is pulled out with a tool. As long as the latch hole 10 is misaligned with the latch rod 13, the handle 18 can be released to continue to do other work. The piles are pulled out in sequence to complete the recycling, which effectively saves construction costs, improves work efficiency, and reduces working time.
