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.

[0027] See also Figure 1-Figure 5 The utility model provides a prestressed high-strength concrete pipe pile with a protective coating structure, which includes a pipe pile body 1 and a support tray 2.

[0028] Reference Figure 1 and Figure 3As shown, support trays 2 are provided on the outer walls at both ends of the pipe pile body 1, and a protective structure 3 is provided on one side of the support tray 2 on the outer wall of the pipe pile body 1. The protective structure 3 includes a closed primer layer 301, an adhesive layer 302 and an anti-corrosion layer 303.

[0029] In order to enhance the bearing capacity and stability of the soil and solve the problems of foundation settlement, settlement difference and foundation lateral displacement during the construction process, concrete pipe piles are usually used to strengthen it. However, traditional concrete pipe piles may cause corrosion and other phenomena during long-term use, thereby damaging the pipe piles and affecting the overall service life. By setting up a protective structure 3, the pipe piles are protected and their service life is increased.

[0030] Reference Figure 1 and Figure 2 As shown, built-in grooves 4 are evenly opened on the inner wall of the pipe pile body 1, and the interior of the built-in grooves 4 is provided with a reinforcement structure 5, which includes a reinforcement support 501, a clamping block 502, a built-in reinforcement tube 503 and a clamping groove 504. The reinforcement supports 501 are all arranged inside the built-in grooves 4, and the side of the reinforcement supports 501 away from the built-in grooves 4 is provided with a clamping block 502. The inner side of the pipe pile body 1 is provided with a built-in reinforcement tube 503, and the outer wall of the built-in reinforcement tube 503 is evenly opened with clamping grooves 504. The built-in grooves 4 are evenly distributed on the inner wall of the pipe pile body 1. The built-in grooves 4 and the reinforcement supports 501 form a clamping structure, and the clamping blocks 502 are all arranged inside the clamping grooves 504. The clamping blocks 502 and the built-in reinforcement tube 503 form a clamping structure through the clamping grooves 504.

[0031] In the process of using pipe piles to strengthen the foundation strength, the traditional pipe piles are insufficient in strength and may be damaged during use, which is not conducive to subsequent use and causes unnecessary losses. By providing a reinforcement structure 5, it is convenient to strengthen the overall strength of the pipe piles, so that they are not easily damaged during use, thereby reducing the losses incurred during use and increasing their service life.

[0032] Reference Figure 1 , Figure 4 and Figure 5As shown, an assembling structure 6 is evenly arranged at the top of the pipe pile body 1, and the assembling structure 6 includes a protrusion 601, a groove 602, a through hole 603, a threaded hole 604 and an assembling bolt 605. The protrusion 601 is evenly arranged at the top of the pipe pile body 1, and the groove 602 is evenly opened at the bottom of the pipe pile body 1. Through holes 603 are opened on the outer wall of the protrusion 601, and a threaded hole 604 is opened on one side of the groove 602 on the outer wall of the pipe pile body 1. Assembling bolts 605 are arranged inside the threaded hole 604. The protrusions 601 are evenly distributed at the top of the pipe pile body 1, and the grooves 602 are evenly distributed at the bottom of the pipe pile body 1.

[0033] The traditional pipe pile is an integrated design, and in the actual use process, it may be necessary to change its height according to specific needs. However, it is difficult to assemble the traditional pipe pile conveniently to change the overall height, so it has certain limitations in the use process. By setting the assembly structure 6, it can be conveniently assembled to facilitate the change of the overall height, thereby greatly increasing the practicality of the device.
