Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipe piles, in particular to anti-splitting precast concrete pipe piles. Background Art

[0002] Concrete pipe piles can be divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles. The pre-tensioned prestressed pipe pile is a kind of hollow cylindrical slender concrete precast member made by the pre-tensioned prestressed process and the centrifugal molding method, mainly composed of a cylindrical pile body, an end plate, a steel sleeve hoop, etc. The prestressed concrete pipe pile is a precast concrete pile reflecting the contemporary concrete technology progress and the high-tech level of concrete products. The traditional pipe pile is generally cylindrical. When the pipe pile is driven into the ground, due to its cylindrical shape, there are some problems. The precast concrete pipe pile is easily affected by the external natural environment, resulting in the surface of the precast concrete pipe pile being exposed to high temperature, causing the problem of cracking of the concrete pipe pile. Moreover, the bottom of the concrete pipe pile is not firm after being inserted into the ground, and the pipe pile is prone to tilt. Therefore, the anti-splitting precast concrete pipe pile is proposed, which can strengthen the anti-cracking ability of the concrete pipe pile and improve the stability of the bottom. Summary of the Utility Model

[0003] Aiming at the problems in the prior art, the utility model provides an anti-splitting precast concrete pipe pile, which can strengthen the anti-cracking ability of the concrete pipe pile and improve the stability of the bottom.

[0004] The technical solution adopted by the utility model to solve its technical problems is an anti-splitting precast concrete pipe pile, including a top cover and a base. Both sides of the top cover and the base close to each other are provided with second slots for the two ends of the concrete pipe pile body to be installed and inserted. One side of the top cover close to the base is provided with a first slot, and a through slot is arranged inside the base. There are two first slots and through slots respectively, and the first slot is adapted to the through slot. The through slot is used for the arc-shaped steel plate to pass through, and the first slot is used for one end of the arc-shaped steel plate to be installed and inserted. There are two arc-shaped steel plates.

[0005] By adopting the above technical solution, the setting of the arc-shaped steel plate can protect the concrete pipe pile from being affected by the external natural environment and improve the anti-cracking ability of the concrete pipe pile.

[0006] By the setting of the base, the bottom area of the bottom of the concrete pipe pile can be increased, and the setting of the annular cutting edge can increase the stability of the concrete pipe pile inserted into the ground, making the concrete pipe pile not easy to tilt.

[0007] Specifically, the outside of the base is provided with second bolt holes, and the inside of the arc-shaped steel plate is provided with third bolt holes, and the second bolt holes are adapted to the third bolt holes.

[0008] By adopting the above technical solution, multiple bolts passing through the second bolt holes and the third bolt holes can fix the arc-shaped steel plates.

[0009] Specifically, anti-corrosion and rust-proof paint is sprayed on the outer surfaces of the two arc-shaped steel plates, and there is a gap between the two arc-shaped steel plates.

[0010] By adopting the above technical solution, a proper buffer pad is filled in the gap between the arc-shaped steel plate and the concrete pipe pile body, so that the buffer pad provides proper protection for the concrete pipe pile body.

[0011] Specifically, an annular cutting edge is fixedly installed on one side of the base away from the top cover.

[0012] By adopting the above technical solution, when the concrete pipe pile body needs to be inserted into the ground, the base is inserted downward into the ground. Through the setting of the base, the area of the bottom of the concrete pipe pile body can be increased, and combined with the insertion of the annular cutting edge, its stability can be improved to avoid tilting.

[0013] Specifically, a plurality of first bolt holes are provided on the sides of the top cover and the base away from each other, and there are multiple first bolt holes.

[0014] By adopting the above technical solution, multiple bolts pass through the first bolt holes and both ends of the concrete pipe pile body, so that the concrete pipe pile body is fixedly connected to the top cover and the base.

[0015] Advantages of the present utility model:

[0016] (1) For the anti-splitting precast concrete pipe pile of the present utility model, through the setting of the arc-shaped steel plate, the concrete pipe pile can be protected from the influence of external natural environment, and the anti-cracking ability of the concrete pipe pile can be improved.

[0017] (2) For the anti-splitting precast concrete pipe pile of the present utility model, through the setting of the base, the bottom area of the bottom of the concrete pipe pile can be increased, and combined with the setting of the annular cutting edge, the stability of the concrete pipe pile inserted into the ground can be increased, so that the concrete pipe pile is not easy to tilt.
