[0002] Precast pipe piles are hollow cylindrical slender concrete precast components made by prestressing technology and centrifugal forming. They are mainly composed of a cylindrical pile body, end plates and steel sleeves. Precast concrete pipe piles are usually used in soft soil foundations to improve the bearing capacity of the soil layer and transfer the load of the superstructure to the deep stable soil layer, thereby reducing foundation settlement and uneven settlement of buildings.
[0003] In the prior art, a Chinese patent with a publication number of CN114108615A is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: This application discloses a prefabricated pipe pile, including a pipe pile body and an end plate, wherein the end plate is located at the end of the pipe pile body, and the pipe pile body includes a shell and a pile body, wherein the shell is made of an anti-corrosion polymer material, and the inner wall of the shell has a plurality of protrusions; the pile body is a concrete cylinder, and the pile body is formed in the shell. The pile body is formed in the shell, which is acid- and alkali-resistant, corrosion-resistant, high in strength, and high in toughness, and can protect the concrete pile body, prevent the pile body from being infiltrated and corroded by groundwater, and maintain the bearing capacity of the pile body.

DETAILED DESCRIPTION
[0024] The present invention is further described in detail below in conjunction with the embodiments:
[0025] Example 1
[0026] like Figure 1-5 As shown, the utility model provides a top reinforced prefabricated pipe pile, a top reinforced prefabricated pipe pile, comprising a pipe pile 1, an inner wall of the pipe pile 1 is provided with a first steel bar 2, and an outer wall of the first steel bar 2 is provided with a first steel ring 3.
[0027] The outer wall of the fixed pipe pile 1 is fixedly connected with a pipe body outer ring 4, and the outer wall of the fixed pipe body outer ring 4 is provided with an external thread 5. The pipe pile 1 can be embedded in the ground as a load-bearing component of a building or structure to play a stabilizing and reinforcing role. When the foundation soil is poor or the building is large in volume and weight and causes deformation, the pipe pile 1 can limit the deformation within the allowable range, and the pipe pile 1 can enhance the stability of the soil and prevent the soil from sliding and settling. Finally, the pipe pile 1 increases the foundation bearing capacity by increasing the foundation area, dispersing the load, etc., and enhances the safety and stability of the building. The steel bars in the pipe pile 1 can help the pipe pile 1 improve its bearing capacity and stability. When the pipe pile 1 is subjected to a vertical load, the first steel bar 2 can increase the strength and rigidity of the pile and enhance the bearing capacity of the concrete in the pile. At the same time, the use of the first steel bar 2 can also increase the bonding force and friction force of the pile end, and enhance the stability and bearing capacity of the pile. The first steel ring 3 can reinforce the steel bars, respectively at the bottom, top and middle part of the pipe pile 1, which can enhance the seismic and crack resistance of the pipe pile 1. The outer wall of the pipe body outer ring 4 has an external thread 5, which can be used to connect with the pipe cap 6.
[0028] The outer wall of the fixed external thread 5 is threadedly connected to the inner wall of the pipe cap 6 through the internal thread 7. The inner wall of the pipe cap 6 has the internal thread 7. The pipe cap 6 can protect the top of the pipe pile 1 from external factors such as impact and wear, thereby extending the service life of the pipe pile 1, making the force on the pile top more reasonable, and improving the bearing capacity and stability of the foundation of the pipe pile 1.
[0029] Example 2
[0030] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the inner wall of the fixed pipe cap 6 is welded with a pile top fixing plate 8, which is used to install and fix the second steel bar 12 and the support plate 9, so that the pipe cap 6 can enhance the bearing capacity and reduce plastic deformation, especially in the case of cast-in-place piles, whose strength is usually more than ten times higher than that of concrete. The steel bar can increase the bearing capacity of concrete and make the building more stable and reliable.
[0031] The top of the fixed plate 8 on the top of the fixed pile body is fixedly connected to a support plate 9, and the top of the fixed support plate 9 is fixedly connected to a cross plate 10 for fixing the second steel bar 12 and the second steel ring 13, so that the two can increase the bearing capacity of the pipe cap 6, ensure that the upper structure and the pile foundation form a whole, and help to improve the integrity and stability of the entire foundation structure.
[0032] A second steel bar 12 is fixedly connected to the bottom of the fixed cross plate 10, and a steel bar fixing plate 14 is fixedly connected to the outer wall of the fixed second steel bar 12. The steel bar fixing plate 14 can strengthen the strength of the concrete structure. The second steel bar 12 can serve as the skeleton and support of the concrete structure, and can withstand shear force, extrusion force and bending force in the structure, thereby improving the bearing capacity of the concrete structure. The second steel bar 12 has good anti-corrosion performance, can withstand a variety of environmental conditions and adverse climates, and enhances its reliability in long-term use.
[0033] The top of the fixed support plate 9 is fixedly connected with a cross plate 11, and the cross plate 11 can be added to the support plate 9 to make them tightly combined to ensure the bearing capacity and stability of the support plate 9, to a certain extent, it can adapt to the settlement of the foundation, reduce the adverse effects of the settlement on the structure, and can enhance the strength and stability of the building structure, increase its bearing capacity and durability.
[0034] The outer wall of the fixed support plate 9 is fixedly connected with a second steel ring 13, and the second steel ring 13 can fix the support plate 9. The second steel ring 13 plays a very stable role, which can make the object more solid and reliable. Under the action of earthquake, it can improve the seismic resistance of the foundation to a certain extent, and play a certain limiting role on the displacement of the top of the pipe pile 1, thereby improving the stability and reliability of the foundation. The second steel ring 13 and the second steel bar 12 are usually tightly combined with the concrete. Such a combination can effectively resist the damage of the structure under the action of external forces such as bending or earthquake, making the entire building structure more stable.
[0035] The working principle of the top reinforced prefabricated pipe pile is described in detail below.
[0036] like Figure 1-5 As shown, the fixing plate 8 and the pipe cap 6 at the top of the pile body are welded, and then the support plate 9 is fixed to the four feet at the top, and then a number of second steel bars 12 are cross-fixed, and then the cross plate 10 and the cross plate 11 are used to fix the second steel bars 12 and the support plate 9, and then the thickest second steel ring 13 is used to reinforce it, so that the load of the upper structure is evenly transferred to the pile foundation to avoid stress concentration, which can enhance the bearing capacity and stability of the top of the pipe pile 1, prevent the pile top from being directly impacted and damaged by external forces, and extend the service life of the pile.
[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
