Further, the stockpiling section 2 stores materials such as ore.

Furthermore, the gravel filled in the pile body framework 1 is graded gravel. The graded broken stone is formed by mixing materials such as coarse broken stone aggregate, fine broken stone aggregate, stone chips and the like, wherein the mixing proportion of various materials can be preset, and the requirements of dense grading are met.

In an alternative embodiment of the present invention, as shown in fig. 1 and fig. 2, the pile body framework 1 includes a plurality of first reinforcing bars 101, each first reinforcing bar 101 is a vertical reinforcing bar, an extending direction of the first reinforcing bar 101 is parallel to an axial direction of the pile body framework 1, the first reinforcing bars 101 are uniformly and alternately arranged along a circumferential direction of the pile body framework 1, and the first reinforcing bars 101 are connected by second reinforcing bars 102.

The construction process of the drilled gravel pile comprises the following steps: punching holes on the ground between the stockpiling area 2 and the building foundation 3 in advance, wherein the punching depth needs to penetrate through a soft soil layer to be processed and enter a hard soil layer below the soft soil layer; after the hole is formed, the manufactured pile body framework 1 is placed into the hole, graded broken stones are filled into the accommodating space 104 through the top end opening of the pile body framework 1 after the pile body framework 1 is fixed, and finally the drilled broken stone pile consisting of the pile body framework 1 and the broken stones is formed.

In the drilling gravel pile, the pile body framework 1 can play a limiting role in limiting the gravel inside the pile body framework, and the gravel is guaranteed not to be scattered by the deformed soil body, so that a buffer zone is formed between the stockpiling area 2 and the building foundation 3, the stability of the soil body is improved, and the stability of the building foundation 3 is guaranteed.

And thirdly, due to the arrangement of the drilled gravel pile, the use of rigid piles can be greatly reduced, so that the construction cost is greatly reduced, and the cost is saved.
