[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Examples, such as Figure 1 As shown, this embodiment provides an enlarged head embedded pile, including an enlarged pile 1 and a connection structure for quickly splicing the enlarged pile 1 with an external pile. A concrete enlarged head is cast near the bottom of the pile groove of the enlarged pile 1. The concrete enlarged head is used to enhance the pull-out resistance and bending resistance of the enlarged pile 1 and improve the stability of the building foundation.

[0025] A plurality of annular docking grooves are provided on the outer wall of one end where the enlarged pile 1 and the external pile are assembled. The connection structure includes two connection card plates 2 assembled together. The connection structure also includes a plurality of hinge blocks 21. A plurality of hinge notches are provided on the side walls where the two connection card plates 2 are hinged to each other. The two ends of the hinge blocks 21 are respectively rotatably connected with the hinge notches of the two connection card plates 2. The two connection card plates 2 can rotate around the hinge of the hinge block 21 to adjust the size of the clamping space between the two connection card plates 2. A plurality of strip-shaped clamping strips 22 are fixed on the opposite side walls of the two connection card plates 2. The two connection card plates 2 selectively open and close to adjust the size of the clamping space between the two connection card plates 2. The strip-shaped clamping strips 22 follow the connection card plates 2 away from or into the annular docking groove of the outer wall of the end of the enlarged pile 1 and the external pile, and are used to assemble and disassemble the intersection of the enlarged pile 1 and the external pile, and can be operated according to construction requirements.

[0026] Specifically, Figure 2 , Figure 3 As shown, a mounting notch is provided on the outer wall of one end of the two connecting clamps 2 away from the hinged position, and two half-circular extension rods 241 that are arranged vertically and opposite to each other are provided on the inner wall of the mounting notch. A limiting seat 24 with a diameter larger than that of the extension rod 241 and a half-circular structure is fixed at the end of the extension rod 241. The two limiting seats 24 at the same height of the two connecting clamps 2 are fitted together to form a circular disk, and the waist-shaped locking sleeve 23 is used to lock the two relative side walls of the limiting seats 24 at the same height to fit tightly. A threaded adjustment rod 231 is threadedly inserted into the outer wall on one side of the waist-shaped locking sleeve 23 in the vertical direction, and a connecting disk is fixed to the inner wall on the other side of the waist-shaped locking sleeve 23 in the vertical direction, and the end of the threaded adjustment rod 231 is rotatably connected to the connecting disk. A waist-shaped locking sleeve 23 is sleeved between the upper and lower circular disks, as shown in FIG. Figure 3 The lateral space inside the waist-shaped locking sleeve 23 is larger than the diameter of the circular disk, so that the waist-shaped locking sleeve 23 can be easily placed between the outer sides of the upper and lower circular disks. The extension rod 241 is used to form a support member for supporting the waist-shaped locking sleeve 23 between the limiting seat 24 and the installation notch, and the space between the limiting seat 24 and the side wall of the installation notch is used to clamp the waist-shaped locking sleeve 23. The two vertical side walls of the waist-shaped locking sleeve 23 are adjusted together, and the side wall of the waist-shaped locking sleeve 23 can be used to abut against the inner wall of the installation notch and the side wall of the limiting seat 24, preventing the waist-shaped locking sleeve 23 from lateral separation from the extension rod 241, causing the two connecting clamps 2 to rotate and open around the hinge position, affecting the assembly stability between the enlarged pile 1 and the external pile.

[0027] The specific process of fixing the enlarged pile 1 and the external pile with the two connecting clamps 2 is as follows: first, the pile column is hoisted until it is aligned with the enlarged pile 1 in the upper and lower directions, and then the two connecting clamps 2 are closed, and the threaded adjustment rod 231 is turned by hand to adjust the two vertical side walls of the waist-shaped locking sleeve 23 together, so that the side walls of the waist-shaped locking sleeve 23 are against the inner wall of the installation notch and the side walls of the limit seat 24. The side walls of the limit seat 24 are used as limits to prevent the waist-shaped locking sleeve 23 from sliding over the limit seat 24 along the axial direction of the extension rod 241 and disengaging from the extension rod 241, resulting in the two connecting clamps 2 being away from the hinged position. There is no limit, and then the two connecting clamps 2 are likely to rotate and open around the hinged position at any time, so that the strip clamp 22 follows the connecting clamp 2 away from the annular docking groove on the outer wall of the end of the enlarged pile 1 and the external pile, resulting in the loss of limit at the intersection of the enlarged pile 1 and the external pile, thereby causing the enlarged pile 1 and the external pile to be unable to be stably assembled.

[0028] The existing method of assembling piles with bolts is changed, thereby saving time for rotating and tightening bolts. At the same time, multiple strip clips 22 are respectively inserted into the annular docking grooves of the outer walls of the ends of the enlarged pile 1 and the external pile. The outer walls of the strip clips 22 are used to abut against the upper and lower side walls in the annular docking groove to ensure the longitudinal pull-out resistance of the connecting clip 2, which is not easy to separate. Ensure stable and fast assembly between the enlarged pile 1 and the external pile, without frequent correction of the position of the external pile, improve assembly efficiency, and thus shorten the construction period.

[0029] In this embodiment, the waist-shaped locking sleeve 23 is a die-cast structure made of stainless steel. Figure 4 As shown, by manually rotating the threaded adjustment rod 231, the two vertical side walls of the waist-shaped locking sleeve 23 can be quickly adjusted together.

[0030] Furthermore, the outer wall of the limiting seat 24 does not extend out of the outer wall of the connecting clamping plate 2, so as to prevent the limiting seat 24 from protruding out of the installation gap, occupying more space, and affecting the smooth sinking and installation of the external pile along the pile groove.

[0031] In addition, a plurality of V-shaped notches 221 are provided on the outer wall of the strip-shaped card strip 22, and a plurality of protruding card blocks 11 engaging with the notches 221 are fixed on the radial side wall of the annular docking groove. Figure 5 and Figure 6 As shown, after the strip clamping strip 22 is inserted into the annular docking groove, the notch 221 is inserted into the outer wall of the protruding clamping block 11 on the inner wall of the annular docking groove to prevent the external pile and the enlarged pile 1 from rotating relative to each other and affecting stability.

[0032] Of course, the above-mentioned notch 221 is inserted into the outer wall of the protruding block 11 on the inner wall of the annular docking groove to limit the rotation of the external pile, which can provide a power source with torque at the end of the uppermost external pile to drive all the pile bodies spliced ​​together to rotate, so that all the piles can be further drilled into the deep coating during the rotation process, which is also applicable to the installation operation of other piles that need to be drilled into the pile groove.

[0033] like Figure 7 and Figure 8 As shown in the figure, the configuration designs for other scenarios are given, among which a, b, c, d, and f are engineering implementation cases. Figure 8 A simplified diagram of the stress state analysis is given.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
