Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] As attached Figure 1-5 The pile head repair template quick installation and disassembly device shown includes a first arcuate semi-ring 1 and a second arcuate semi-ring 2. A hinge 3 is installed at one end of the connection between the first arcuate semi-ring 1 and the second arcuate semi-ring 2 by screws, and the first arcuate semi-ring 1 and the second arcuate semi-ring 2 are movably connected by the hinge 3. The first arcuate semi-ring 1 and the second arcuate semi-ring 2 are symmetrically distributed and have the same size. A casting cavity 11 is formed between the first arcuate semi-ring 1 and the second arcuate semi-ring 2.

[0025] Specifically, in this structure, one end of the first arcuate semi-ring 1 and the second arcuate semi-ring 2 can be unfolded and closed by a hinge 3, so that the first arcuate semi-ring 1 and the second arcuate semi-ring 2 can be conveniently installed at the pile head that needs to be repaired, and the casting cavity 11 formed between the first arcuate semi-ring 1 and the second arcuate semi-ring 2 is used by construction personnel to pour mixed soil materials into the casting cavity 11 to realize the repair operation on the pile head.

[0026] In a specific embodiment, as shown in the attached Figure 1 , 2 As shown in , 4, a locking structure is provided at the connection between the other ends of the first arcuate semi-ring 1 and the second arcuate semi-ring 2, and the locking structure includes a first support block 4, the first support block 4 is fixedly mounted on the outer wall of the first arcuate semi-ring 1, and the outer wall of the second arcuate semi-ring 2 is mounted with a second support block 5, one end of the first support block 4 is provided with a support rod 6, one end of the support rod 6 is provided with a docking joint 7, one end of the docking joint 7 is provided with a threaded head 8, one end of the second support block 5 is provided with a rotating rod 9, one end of the rotating rod 9 is provided with a threaded cap 10, one end of the rotating rod 9 is rotatably connected at the second support block 5, the inner wall of the threaded cap 10 is threadedly connected to the outer wall of the threaded head 8, and the outer surface of the threaded cap 10 is provided with anti-slip grooves 12.

[0027] Specifically, in this structure, after the first arc-shaped semi-ring 1 and the second arc-shaped plate semi-ring are closed into a circular shape and installed at the pile head that needs to be repaired, the threaded head 8 at the docking joint 7 corresponds to the threaded cap 10. The operator rotates the threaded cap 10 to rotate the rotating rod 9 at one end of the threaded cap 10 at the second support block 5. After the threaded cap 10 and the threaded head 8 are docked and rotated, the threads of the threaded cap 10 and the threaded head 8 are locked, and then one end of the first arc-shaped semi-ring 1 and the second arc-shaped semi-ring 2 can be locked and connected, so that it is convenient to install on the pile head that needs to be repaired, and at the same time, it is convenient for construction personnel to disassemble it.

[0028] In a specific embodiment, as shown in the attached Figure 1 , 3 As shown in , 5, the inner walls of the first arcuate semi-ring 1 and the second arcuate semi-ring 2 are both installed with an adhesive outer film 13, the adhesive outer film 13 is consistent in size with the inner walls of the first arcuate semi-ring 1 and the second arcuate semi-ring 2, a release agent layer is sprayed on the surface of the adhesive outer film 13, the outer wall of the adhesive outer film 13 and the inner walls of the first arcuate semi-ring 1 and the second arcuate semi-ring 2 are both installed with Velcro 14, and the adhesive outer film 13 is detachably connected to the first arcuate semi-ring 1 and the second arcuate semi-ring 2 through the Velcro 14.

[0029] Specifically, in this structure, the adhesive outer film 13 sprayed with a release agent layer is on the inner walls of the first arcuate semi-ring 1 and the second arcuate semi-ring 2, which can not only achieve a quick demoulding effect, but also protect the inner walls of the first arcuate semi-ring 1 and the second arcuate semi-ring 2, thereby preventing the long-term pouring of concrete from causing wear to the inner walls of the first arcuate semi-ring 1 and the second arcuate semi-ring 2, thereby improving the service life and reducing the burden of subsequent cleaning of the first arcuate semi-ring 1 and the second arcuate semi-ring 2;

[0030] The adhesive outer film 13 can be removed and installed through the Velcro 14 and the first arcuate semi-ring 1 and the second arcuate semi-ring 2, so that the adhesive outer film 13 can be easily disassembled and cleaned, thereby realizing the turnover use of the adhesive outer film 13.

[0031] In a specific embodiment, as shown in the attached Figure 1 As shown, the contact surfaces at both ends of the first arcuate semi-ring 1 and the second arcuate semi-ring 2 are provided with sealing gaskets. The provision of the sealing gaskets can increase the sealing effect between the first arcuate semi-ring 1 and the second arcuate semi-ring 2, thereby preventing the concrete from flowing out from the gap between the first arcuate semi-ring 1 and the second arcuate semi-ring 2 when pouring concrete.

After the threaded cap 10 and the threaded head 8 are docked and rotated, the threads of the threaded cap 10 and the threaded head 8 are locked, and finally, the repair material of the pile head, such as concrete, is poured through the pouring cavity 11 formed by closing the first arcuate semi-ring 1 and the second arcuate semi-ring 2;

[0033] After the pouring repair is completed, the locking of the threaded cap 10 and the threaded head 8 is released, and the first arc-shaped semi-ring 1 and the second arc-shaped semi-ring 2 are unfolded through the hinge 3 to realize the disassembly operation of the device;

[0034] The operator can remove the adhesive outer film 13 from the inner wall of the first arc-shaped semi-ring 1 and the second arc-shaped semi-ring 2 through the Velcro 14, and the adhesive outer film 13 can be cleaned and reused.

[0035] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
