[0002] PHC pipe piles have the advantages of strong bearing capacity, good stability, fast construction speed, good durability and environmental friendliness. They have been widely used in the foundations of photovoltaic power generation devices and other building structures.
[0003] PHC piles are generally prestressed high-strength concrete round tubes with a diameter of 100mm to 800mm and a wall thickness of 70mm to 100mm. They usually have a metal end plate at the top and a truncated prestressed reinforced concrete tube at the bottom. During use, the bottom needs to be blocked sometimes for project needs. Generally, traditional closed-end steel pile tips are used in projects. However, in projects with large workloads, such as photovoltaic projects, the economic efficiency of steel pile tips is poor and often difficult to implement. If on-site filling concrete is used for blocking, traditional molds are difficult to adapt. First, because the length of PHC piles is more than 5 meters, traditional wooden molds are difficult to install inside the pipe cavity. Second, affected by the centrifugal production process of PHC piles, the inside of the pile cannot be guaranteed to be round, and it is generally an irregular ellipse. Traditional wooden molds and steel molds cannot be uniformly adapted, and the sample processing volume is huge. Summary of the invention
[0004] The present application aims to solve at least one of the above-mentioned technical problems in the prior art to a certain extent. To this end, the present application provides a pipe pile end plugging device, which solves the problems of high cost of using finished steel pile tips to plug the pipe pile ends in the prior art and poor adaptability between the mold and the inside of the pipe pile in the traditional cast-in-place plugging process.

[0014] In an alternative or preferred embodiment, two second steel members are provided, and the two second steel members are respectively located on both sides of the pipe pile.
[0015] In an alternative or preferred embodiment, the first steel member is an angle steel or a channel steel.
[0016] In an alternative or preferred embodiment, the connecting member is a deformed bar.

[0027] PHC pipe piles have the advantages of strong bearing capacity, good stability, fast construction speed, good durability and environmental friendliness, and are widely used in the foundations of other building structures such as the foundations of photovoltaic power generation devices.
[0028] PHC pipe piles are generally prestressed high-strength concrete circular pipes with a diameter of 300 mm to 800 mm and a wall thickness of 70 mm to 200 mm. Usually, the top end is provided with an end plate made of metal material, and the bottom end is a truncated prestressed reinforced concrete pipe. During use, in order to meet the project requirements, the bottom end sometimes needs to be blocked. Generally, traditional closed-section steel pile tips are used in projects. However, in projects with a large amount of work, such as photovoltaic projects, the economy of steel pile tips is poor and it is often difficult to implement. If concrete is filled on-site for blocking, it is very difficult for traditional molds to fit. First, since the length of PHC pipe piles reaches more than 5 meters, it is difficult to install traditional wooden molds inside the pipe cavity. Second, due to the influence of the centrifugal production process of PHC pipe piles, the inside of the pipe piles cannot be guaranteed to be circular and is generally an irregular oval shape. Traditional wooden molds and steel molds cannot be uniformly adapted, and the sample processing volume is huge.
[0029] Referring to Figure 1 , Figure 2 , the present application provides a pipe pile end blocking device, which includes a pipe pile hoop 100, a bracket 200, a connecting piece 300, a template 400 and a rubber pad 500. The pipe pile hoop 100 is used to tightly hoop the outer wall of the pipe pile 600. The bracket 200 is connected to the pipe pile hoop 100. The bracket 200 includes a first steel member 210. The first steel member 210 is spaced from the end of the pipe pile 600. The connecting piece 300 is fixedly connected to the first steel member 210. The first steel member 210 extends into the pipe pile 600. The template 400 is fixed to one end of the connecting piece 300 that extends into the pipe pile 600. The diameter of the template 400 is smaller than the inner diameter of the pipe pile 600. The template 400 is used to horizontally partition the inside of the pipe pile 100. The rubber pad 500 is connected in parallel with the template 400. The diameter of the rubber pad 500 is larger than the inner diameter of the pipe pile 600.
[0030] During use, the pipe pile hoop 100 is tightened around the outer wall of the pipe pile 600. The bracket 200 is connected to the pipe pile hoop 100 so that the first steel member 210 of the bracket 200 is at a certain distance from the end of the pipe pile 600. Then, the formwork 400 is fixed to one end of the connecting member 300, and the connecting member 300 together with the formwork 400 is placed into the pipe pile 600, such that the formwork 400 and the rubber pad 500 are horizontally separated inside the pipe pile 600. The connecting member 300 is connected to the first steel member 210. Micro-expansive concrete is poured at the other end of the pipe pile 600. The formwork 400 and the rubber pad 500 can block the micro-expansive concrete. After the concrete solidifies, a plugging section is formed in the pipe pile 600 from the end of the pipe pile 600 to the formwork 400. Compared with using a finished steel pile tip to plug the end of the pipe pile 600, this plugging device for plugging the end of the pipe pile 600 has a lower cost and better economy. Moreover, the expansibility of the filled micro-expansive concrete can ensure that the concrete is closely attached to the side wall of the pipe pile 600. The connection of the pipe pile hoop 100, the bracket 200, and the connecting member 300 can limit the displacement of the formwork 400 extending into the inner cavity of the pipe pile 600, ensuring the forming effect of the concrete inside the pipe pile 600. The rubber pad 500 can adapt to the shape inside the pipe pile 600. Therefore, this application solves the problems in the prior art that using a finished steel pile tip to plug the end of the pipe pile has a high cost, and the adaptability between the mold and the inside of the pipe pile is poor during the traditional in-situ plugging process.

[0038] In some embodiments, there are two second steel members 220, and the two second steel members 220 are respectively located on both sides of the pipe pile 600.
[0039] Specifically, the two second steel members 220 are respectively connected to the first steel member 210, so that the first steel member 210 is supported by the two second steel members 220, making the first steel member 210 more stable. All four connecting members 300 are welded to both sides of the middle of the first steel member 210.
[0040] In some embodiments, one end of the second steel member 220 is detachably connected to the pipe pile hoop 100, and the other end is detachably connected to the first steel member 210.
