Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete square piles, in particular to a reinforced prefabricated concrete square pile. Background Art
[0002] Pile foundation construction is a common composite foundation reinforcement method. According to the production method of pile foundation, it can be divided into prefabricated piles and cast-in-place piles. Prefabricated square piles are a type of prefabricated piles, that is, piles with a rectangular cross-section. They are widely used in various fields such as roads and bridges. Prefabricated square piles are directly transported to the construction site after being produced in the factory, and then the prefabricated pipe piles are pre-buried in the foundation by mechanical vibration. However, the connection force between the pile foundation and the surrounding foundation is relatively poor, which affects the stability of the pile foundation.
[0003] When the concrete square pile is buried in the foundation, the conical surface at the bottom of the pile is prone to damage during the embedding process. After damage, it is easy to cause some cracks on the surface of the pile, thus affecting the quality of the pile. The structural strength is not enough. Due to uneven force, the two ends of the concrete pile are more likely to decompose and crack, and there is greater resistance when piling. For this reason, we provide a reinforced prefabricated concrete square pile. Summary of the invention
[0004] The purpose of the utility model is to provide a reinforced prefabricated concrete square pile to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reinforced precast concrete square pile, comprising a square column body, grooves are arranged on both sides of the square column body, a pile tip is arranged at the bottom of the square column body, a steel covering is arranged on the surface of the pile tip, a plurality of stirrups are arranged in the inner cavity of the square column body, vertical steel bars are arranged at the four corners of the inner cavity of the stirrups, a cross is arranged in the vertical steel bars, and protective steel bars are arranged at the four corners of the inner cavity of the pile tip.
[0006] Preferably, the side surface of the groove is inclined, and the groove extends from the square column body to the pile tip.
[0007] Preferably, the shape of the steel cladding is the same as that of the pile tip, both are quadrangular pyramids, and are welded from four steel plates.
[0008] Preferably, the pile tip is made of metal.
[0009] Preferably, the stirrups, vertical steel bars and crosses are connected by welding.
[0010] Preferably, the surfaces of the pile tip, stirrups, vertical steel bars, cross and protective steel bars are all coated with anti-rust paint.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the prefabricated concrete square pile of the utility model can reduce the contact area with the ground during piling through the pile tip at the lower end of the square pile body and the groove arranged on the side of the square pile body, thereby reducing the resistance to improve the piling efficiency, and the strength of the device can be improved by the arrangement of stirrups, vertical steel bars, crosses, steel coverings, and protective steel bars, and the internal force can be guaranteed to be uniform when an impact occurs, thereby reducing the impact and making the device less likely to crack, and by applying anti-rust paint, the device can effectively avoid rust after being used for a period of time, thereby improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] 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.
[0017] See also Figure 1-3 The utility model provides a technical solution: a reinforced precast concrete square pile, comprising a square column body 1, grooves 3 are arranged on both sides of the square column body 1, a pile tip 2 is arranged at the bottom of the square column body 1, a steel covering 7 is arranged on the surface of the pile tip 2, a plurality of stirrups 4 are arranged in the inner cavity of the square column body 1, vertical steel bars 5 are arranged at the four corners of the inner cavity of the stirrups 4, a cross 6 is arranged in the vertical steel bars 5, and protective steel bars 8 are arranged at the four corners of the inner cavity of the pile tip 2. The pile tip 2 and the groove 3 are better driven into the ground to reduce effective resistance. The strength of the device is improved by the arrangement of stirrups 4, steel bars 5, crosses 6, and protective steel bars 8, so that the square pile can withstand greater impact.
[0018] The side surface of the groove 3 is inclined, and the groove 3 extends from the square column body 1 to the pile tip 2, which can reduce the force-bearing area when driving into the ground, reduce resistance and increase ease of driving into the ground.
[0019] The shape of the steel coating 7 is the same as that of the pile tip 2, both are quadrangular pyramids, and are welded from four steel plates. The inclined pile tip 2 and the steel coating 7 can better protect the material, reduce the contact area, and drive it into the ground with the least force.
[0020] The pile tip 2 is made of metal. The metal cone tip 2 has higher strength and is not easy to break when hit, which is convenient for reducing damage to the bottom part of the square pile when it is inserted into the ground, thereby improving the strength of the precast concrete square pile and allowing the precast concrete square pile to be stably buried in the ground.
[0021] The stirrups 4, the vertical steel bars 5 and the cross 6 are connected by welding, so that the device is more solid and the strength is improved. When an impact occurs, the internal force can be evenly distributed, thereby reducing the impact and making the device less likely to crack.
[0022] The surfaces of the pile tip 2, stirrups 4, vertical steel bars 5, cross 6, and protective steel bars 8 are all coated with anti-rust paint. The coating of anti-rust paint can effectively prevent the device from rusting after a period of use, thereby better protecting the device and improving the practicality of the device.
[0023] 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.
