[0002] Special-shaped piles are a new type of pile used in geotechnical engineering developed on the basis of traditional round straight piles. They can maximize the potential of the foundation soil and the pile itself. There are two types of so-called special-shaped piles: one is a variable-section special-shaped pile obtained by changing the shape of the longitudinal section of the pile body, which can increase the unevenness and roughness of the pile-soil contact surface in order to increase the side friction and end resistance, such as wedge piles, expanded bottom piles, squeezed expanded branch plate piles, etc.; the other is a special-section pile obtained by changing the geometric shape of the pile section, which can improve the pile side bearing capacity and save materials, such as square piles, wall sheet piles, H-shaped and I-shaped steel piles, and X-shaped piles. In order to explore the bearing characteristics, deformation and failure modes, structural design calculations, etc. of special-shaped piles, most scholars use geotechnical model test methods to explore.

[0032] The utility model is further described in detail below with reference to the accompanying drawings:
[0033] Example 1
[0034] like Figure 1 , 2 As shown, the utility model is a detachable fine filling device, including a panel unit 1, a slide rail unit 2, a connector 3, a fixing member 4 and a pressurized compaction unit 5. The panel unit 1 is arranged in a square shape on the outside of the test pile 6, and the panel unit 1 includes four groups of basic panels, each group of basic panels includes a plurality of first basic panels 11 and second basic panels 12; in this embodiment, each group of basic panels includes two first basic panels 11 and four second basic panels 12, the two basic panels 11 constitute a first basic panel group, and the four second basic panels 12 constitute a second basic panel group, the first basic panel group is arranged on one side of the second basic panel group, the two relatively arranged groups of basic panels have the same structural dimensions, and the two adjacent basic panel groups are symmetrical about the straight line A. At the same time, the number and size of the first basic panels 11 and the second basic panels 12 are determined according to the test pile 6.
[0035] The first base plate 11 is provided with first through holes 13 at both ends, specifically one at each end; the second base plate 12 is provided with second through holes 14 at both ends, specifically two at each end. The size of the first through hole 13 is the same as the size of the second through hole 14. It should be noted that the axis of the second through hole 14 is parallel to the axis of the first through hole. In addition, the axis of the first through hole 13 at the same end is between the axes of the two second through holes 14. In addition, rectangular holes 131 are provided on both sides of the first through hole 13.
[0036] The slide rail unit 2 is arranged on the side of the base panel away from the test pile 6 and is located at both ends of the first base panel 11 and the second base panel 12. Figure 3 As shown, each set of slide rail units 2 includes a slider 21 and a guide rail 22. The guide rail 22 is arranged on the side of the second base panel 12 away from the test pile 6. The guide rail 22 is arranged at one end of the slider 21. The slider 21 near the end of the guide rail 22 passes through the inside of the guide rail 22 and is detachably connected to the guide rail 22. Figure 4 As shown, a groove 23 is provided on the side of the slider 21 facing the second base panel 12. It should be noted that the groove 23 is rectangular, and a polygonal groove is provided in the middle of the shorter side. The groove 23 is adapted to the structural size of the slider 21, and is clearance-matched with the slider 21. A plurality of third through holes are provided in the middle of the slider 21, matching the first through hole 13, and a fourth through hole is provided on the guide rail 22, matching the second through hole 14. Finally, the first through hole 13, the second through hole 14, the third through hole and the fourth through hole are all the same in size and shape.
[0037] The connecting member 3 passes through the first through hole 13 on the first base panel 11 and the third through hole on the slider 21 in sequence and is fixedly connected to the fixing member 4, specifically by threaded connection; the connecting member 3 passes through the second through hole 14 on the second base panel 12 and the fourth through hole on the guide rail 22 in sequence and is fixedly connected to the fixing member 4, specifically by bolt connection. Since one end of the slider 21 is deeply inserted into the groove 23 in the guide rail 22, one side of the base panel can be fixed, and the base panels on the other sides are fixed in the same way, and the test pile 6 and the soil are surrounded together. In this embodiment, as shown in FIG. Figure 5 As shown, the connecting member 3 is a bolt, the fixing member 4 is a nut, the connecting member 3 is arranged on the side of the panel unit 1 close to the test pile 6, and the fixing member 4 is arranged on the side of the slider 21 or the guide rail 22 away from the test pile 6, and the connecting member 3 and the fixing member 4 are fixedly connected.

[0039] Example 2
[0040] The utility model discloses a method for using a detachable fine filling device. After the detachable fine filling device surrounds the soil and the test pile 6, in this embodiment, a pressure pad 51, a jack 52 and another pressure pad 51 are placed on the C side in sequence to start jacking. Figure 6 As shown, the base panel on the C side is moved forward. During the movement, since rectangular holes 131 are provided on both sides of the first base panel 11, and the size of the rectangular hole 131 is adapted to the connecting member 3, the head of the connecting member 3 can pass through the rectangular hole 131, so that the base panel on the C side can continue to move forward. Then, the first base panel 11 at the rightmost end of the D side will be exposed outside the test pile 6 and the soil. When the first base panel 11 at the leftmost end of the C side is aligned with the first base panel 11 at the rightmost end of the D side, the first base panel 11 at the edge corresponding to the D side can be disassembled. The disassembly process is as follows: first, the fixing member 4 on the two sliders 21 on the D side is disassembled from the outside, and then the slider 21 is moved into the groove 23, so that the third through hole at the rightmost end of the slider 21 is aligned with the first through hole 13 of the other first base panel 11, and the connecting member 3 is used to pass through the first through hole 13 of the other first base panel 11 to connect with the fixing member 4, and finally, the extra first base panel 11 is removed.
[0041] The side corresponding to the D side is the B side. After the first base panel 11 at the rightmost end of the D side is removed, the fixing parts 4 on the two sliders 21 on the B side can be removed from the outside, and then the slider 21 is moved into the groove 23, so that the third through hole on the side of the slider 21 away from the guide rail 22 is aligned with the first through hole 13 of the other first base panel 11, and the connecting part 3 is used to pass through the first through hole 13 of the other first base panel 11 to connect with the fixing part 4, and finally the redundant first base panel 11 is removed. After the two first base panels 11 are removed, as shown in FIG. Figure 7 As shown, at this time, depending on the actual situation, you can start pushing in from the D side or from the C side.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
