[0017] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0018] like Figure 1-2 As shown in the figure, marks 1-18 respectively represent: pipe pile body 1, rubber waterproof pad 2, pile tip 3, anti-loosening bolt 4, pile body end plate 5, embedded part 6, embedded part fixing hole 7, annular water stop groove 8, bolt reserved hole 9, waterproof structure 10, waterproof structure 11, pile body connecting section 12, reserved hole 13, pile tip bottom plate 14, waterproof pad positioning groove 15, cross rib plate 16, cylindrical head hexagon socket bolt 17, anti-loosening spring 18.

[0019] Example: Figure 1 and Figure 2 As shown, the main body of the mechanically connected pipe pile tip structure in this embodiment is mainly divided into four parts, including the pipe pile body 1, the rubber waterproof pad 2, the pile tip 3, and the anti-loosening bolt 4, wherein the pipe pile body 1 and the pile tip 3 are mechanically connected by the anti-loosening bolt 4, and the rubber waterproof pad 2 is arranged between the pipe pile body 1 and the pile tip 3 to improve the sealing effect of the pile tip.

[0020] It is important to note here that Figure 1In the figure, there is actually only one pile tip 3. The side view of the pile tip 3 is located in the middle position of the figure, and the front view of the pile tip 3 is located on the right side of the figure, so as to reflect the matching relationship between the pile tip 3 and other components.

[0021] Specifically, the pile tip 3 is composed of a cross rib plate 16, a pile tip bottom plate 14 and a pile body connecting section 12. The pile body connecting section 12 and the cross rib plate 16 are respectively arranged on both sides of the pile tip bottom plate 14, wherein the pile body connecting section 12 corresponds to the position of the pipe pile body 1, and the cross rib plate 16 is located on the other side.

[0022] Compared with the conventional cross pile tip, the present embodiment adds a pile body connection section 12 to the pile tip 3. The first function of the pile body connection section 12 is to increase the connection ability between the pile tip 3 and the pipe pile body 1. When connecting, the pile body connection section 12 can be inserted into the pile hole of the pipe pile body 1. After the connection is completed, the shear resistance of the pile tip is increased, and the rock penetration ability of the inclined bearing layer is increased. The second function of the pile body connection section 12 is to serve as a positioning mark for the installation connection of the pile tip 3, saving manpower and increasing the construction speed.

[0023] In this embodiment, a waterproof pad positioning groove 15 is set on the pile tip bottom plate 14, so that the rubber waterproof pad 2 can be positioned before installation. After installation, the contact between the rubber waterproof pad 2 and groundwater can be reduced, the oxidation of rubber can be reduced, and the service life of the rubber waterproof pad 2 can be increased.

[0024] The rubber waterproof pad 2 is located between the pile tip 3 and the pipe pile body 1. The material is rubber and is formed by a mold in one time. Its main function is to prevent groundwater from penetrating into the interior of the pipe pile body 1. When installing, it is first installed on the pile tip 3 according to the waterproof pad positioning groove 15 on the pile tip 3 and installed at the same time as the pile tip 3. In addition to the end plate waterproofing, the rubber waterproof pad 2 is provided with two waterproof structures and a pile body connecting section waterproof pad. The waterproof structure 10 refers to the thickening around the bolt reserved hole 9, which is more severely extruded and deformed after installation, thereby isolating water from penetrating from the bolt reserved hole 9. The waterproof structure 11 is connected to the annular water stop groove 8 of the pile body end plate 5. The waterproof structure 11 is convex, and the convex radius is larger than the radius of the annular water stop groove 8. After installation, the convexity is severely extruded and deformed, thereby enhancing the waterproof effect. The pile body connection section waterproof pad is located between the interior of the pipe pile body 1 and the pile body connection section 12 of the pile tip 3. Its functions are to increase the connection performance between the pile body connection section 12 and the pipe pile body 1 and to increase secondary waterproofing.

[0025] The end of the pipe pile body 1 is provided with a pile body end plate 5, and 8 embedded parts 6 are welded at this position. An embedded part fixing hole 7 is provided at the bottom of each embedded part 6. During installation, each embedded part fixing hole 7 is fixed by a circular steel bar passing through it, and is connected to the steel bar of the pipe pile body 1, and cast together with the pile body, thereby improving the structural performance of each embedded part 6. An annular water stop groove 8 is provided on the pile body end plate 5. After installation, the annular water stop groove 8 is closely fitted with the waterproof structure 11 on the rubber waterproof pad 2 to form a waterproof structure, thereby enhancing the waterproof effect.

[0026] The anti-loosening bolt 4 is responsible for connecting the pile tip 3, the rubber water-proof pad 2 and the pile body 1. The anti-loosening bolt 4 is composed of an anti-loosening spring 18 and a cylindrical head hexagon socket bolt 17. The anti-loosening bolt 4 is installed by an electric screwdriver. During installation, the cylindrical head hexagon socket bolt 17 passes through the reserved hole 13 on the pile tip 3 and the bolt reserved hole 9 on the rubber water-proof pad 2 to the bolt hole of the embedded part 6 in sequence; after installation, the anti-loosening spring 18 is squeezed to generate an outward elastic force, squeeze the bolt body, and interact with the internal thread of the embedded part 6 to prevent the bolt from loosening and falling off by itself.

[0027] In the specific implementation of this embodiment: Figure 1 As shown, the reserved holes 13 on the pile tip 3 are evenly spaced along its circumference. At this time, the pile body 1 is also provided with embedded parts 6 of matching quantity and position, and the rubber waterproof pad 2 is also provided with reserved bolt holes 9 of matching quantity and position, so as to ensure the connection performance between the pile tip 3 and the pile body 1.

[0028] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the utility model without departing from the scope of the claims, so they are not described one by one here.
