[0002] Gravel piles are composite foundation reinforcement piles made of crushed stone (pebbles) as the main material. Gravel piles and sand piles are collectively referred to as loose piles or coarse-grained soil piles abroad. The so-called loose piles refer to piles without bonding strength. The composite foundation composed of loose piles such as gravel columns or sand piles and soil between piles can also be called loose pile composite foundation. The composite foundations such as gravel piles, sand piles, and slag piles widely used at home and abroad are all loose pile composite foundations. Gravel piles are suitable for compacting loose sand, silt, plain fill and miscellaneous fill foundations. Among the various types of piles in the composite foundation, gravel piles and sand piles are both loose material piles with similar reinforcement mechanisms. The mechanism varies with the different types of soil to be reinforced: it has a displacement and compaction effect on sand, silt and gravel soil; for clay and fill, it is mainly a displacement effect, and has different degrees of compaction and drainage consolidation. Gravel piles are mainly used in engineering projects to reinforce soft foundations, reinforce dam slopes, eliminate the liquefaction of liquefiable sand, and eliminate the collapsible properties of collapsible loess.

[0027] In this device, the pile body 1 is assembled, and the pile body 1 is lifted by a lifting device, which is directly connected to the connector 4. When the entire device enters a pre-opened hole in the ground, the top mounting frame 3 fits into the hole.
[0028] The inner annular array of the clamp 2 has a telescopic controller 13 , and a telescopic cylinder 14 is installed on the front of the telescopic controller 13 , and the front of the telescopic cylinder 14 passes through the clamp 2 .
[0029] A plurality of groups of clamps 2 are installed outside the pile body 1. The clamps 2 are directly clamped in the annular clamping grooves 7. When the equipment enters the hole on the ground, the capping stone 9 outside the clamps 2 will fit the inner wall of the hole.
[0030] A capping stone device 9 is installed on the front side of the telescopic cylinder member 14, and a stone transfer tube 12 is provided at the top and bottom ends of the capping stone device 9.
[0031] Six capping stones 9 are installed on the outside of each clamp 2 and are located in six different directions. The capping stone 9 is used to realize drilling and stone burying operations, and each capping stone 9 can be controlled to continuously retract and retract through the cylinder structure on the back. Specific embodiment 2:
[0033] Reference Figure 1-6 A connecting column 10 is connected between the clamps 2, and a striking head 11 is installed in the middle of the front of the capping stone 9. In order to prevent the clamps 2 from loosening due to vibration, a connecting column 10 is installed between the adjacent upper and lower clamps 2.
[0034] Both sides of the front side of the capstone 9 are provided with stone outlet holes 15 , and the middle part of the capstone 9 is provided with an inner conveying channel 16 .
[0035] An opening 17 is formed on one side of the inner conveying channel 16 , and an inclined plate 18 is installed on one side of the opening 17 on the inner conveying channel 16 , and the inclined plate 18 is inclined toward the direction of the stone outlet hole 15 .
[0036] The width of the interior of the inner delivery channel 16 and the gap between the inner delivery channel 16 and the stone outlet hole 15 in the cap stone device 9 can only accommodate one stone.
[0037] First, start the telescopic controller 13 of each capping stone 9. After the telescopic controller 13 is started, it will control the telescopic cylinder 14 to continue to telescope. Here, the telescopic cylinder 14 is a complete cylinder drive component. During the telescopic process of the capping stone 9, the striking head 11 on the surface will make a spherical pit mark on the wall, and by rotating the pile body 1, a circular array of spherical pit marks will be left in the hole, and the gravel can be driven into the ball pit later. In this embodiment, the power supply line and control line of the telescopic controller 13 pass through the clamp 2 and are connected to the outside.

When the top stone device 9 is extended and retracted back and forth, the gravel will be driven into the ball pit.
[0039] It should be noted that the inner delivery channel 16 will tilt to one side, and the opening 17 can only accommodate one stone at a time, so there is no need to worry about blockage. When a piece of gravel enters the opening 17, the previous tight gravel will continue to fall until there is gravel in each stone outlet hole 15. When the gravel is driven into the ball pit, stones are put in again.
