Description

Technical Field

[0001] This utility model relates to the field of PHC pipe pile technology, specifically a new type of prefabricated PHC pipe pile. Background Technology

[0002] PHC pipe piles are short for prestressed high-strength concrete pipe piles. They are manufactured using a pre-tensioned prestressed centrifugal molding process and cured with high-temperature steam. They are widely used in various building and road and bridge projects, including high-rise and multi-story buildings, large-span structures, and industrial plants.

[0003] A search revealed that the announcement number is CN210315506U, entitled "A Precast PHC Pipe Pile," which includes a hollow pile body with a pile head at one end. Research and analysis showed that while it allows some soil below the precast PHC pipe pile to enter the pile body, reduces lateral displacement and uplift of the soil around the precast PHC pipe pile, minimizes vertical compression of the soil around adjacent precast PHC pipe piles, and improves the quality of pile group construction, it also has the following drawbacks to some extent.

[0004] For example, it is impossible to protect the two sides of the pipe pile. Since the outer surface of the two sides of the pipe pile is covered with metal material, it is easy to rust during storage. Since the two ends of the pipe pile cannot be protected against rust, they need to be ground and derusted before welding during construction. This operation not only increases the labor intensity of personnel, but also affects the construction efficiency. At the same time, there is no limiting function during the connection of the two pipe piles, which can easily cause rotation and affect the alignment between the two pipe piles. In order to solve the above technical problems, we have designed a new type of precast PHC pipe pile. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of precast PHC pipe pile with rust prevention and protection function, which eliminates the need for grinding and rust removal, reduces the labor intensity of personnel, and allows for limiting during connection, speeding up alignment and improving construction efficiency. It solves the problems of not being able to protect the two ends of the pipe pile from rust, requiring grinding and rust removal before welding, increasing the labor intensity of personnel, and the inability to limit alignment during connection, which affects construction efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel precast PHC pipe pile, comprising a pipe pile body, a limiting slot being provided at the top of the pipe pile body, a limiting protrusion being fixedly connected to the bottom of the pipe pile body, a protective sleeve being slidably fitted on both the top and bottom of the pipe pile body, a waterproof cloth strip being fixedly connected to the inner side of the protective sleeve, an elastic band being sewn onto the outer surface of the waterproof cloth strip, and Velcro being sewn onto the surface of the elastic band.

[0007] Preferably, the protective sleeve includes a sleeve, a cover plate is fixedly connected to the outside of the sleeve, and protective iron sheets are embedded inside both the sleeve and the cover plate.

[0008] Preferably, both the sleeve and the cover plate are made of polypropylene, and a rubber cushioning pad is glued to the inner side of the cover plate.

[0009] Preferably, the hook and loop fasteners are divided into barbed hook and loop fasteners and soft hook and loop fasteners. The barbed hook and loop fasteners are fixedly connected to the left side of the back side of the elastic strap, and the soft hook and loop fasteners are fixedly connected to the front surface of the elastic strap.

[0010] Preferably, the pipe pile body includes a pile body, with pads fixedly connected to the top and bottom of the pile body, and protective steel rings fixedly fitted to the top and bottom of the outer surface of the pile body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The protective sleeve is placed over both ends of the pipe pile body. The elastic straps are wrapped around the surface of the waterproof cloth strip and pulled tight to secure the waterproof cloth strip and prevent rainwater from contacting the protective steel ring. This can protect the protective steel ring from rust and eliminate the need for personnel to grind and remove rust, thus reducing the labor intensity of personnel.

[0013] By setting limit slots and limit protrusions, the two pipe piles can be limited during splicing, so that the limit protrusion at one end of one pipe pile can be inserted into the limit slot at one end of the other pipe pile. This can prevent the upper pipe pile from rotating during welding and effectively improve construction efficiency. Attached Figure Description

[0019] Please see Figures 1-4A new type of precast PHC pipe pile includes a pipe pile body 1, a limit slot 6 is opened on the top of the pipe pile body 1, a limit protrusion 10 is fixedly connected to the bottom of the pipe pile body 1, a protective sleeve 2 is slidably sleeved on the top and bottom of the pipe pile body 1, a waterproof cloth strip 4 is fixedly connected to the inner side of the protective sleeve 2, an elastic strap 5 is sewn on the outer surface of the waterproof cloth strip 4, and Velcro is sewn on the surface of the elastic strap 5.

[0020] Please see Figure 4 The protective sleeve 2 includes a sleeve 12, and a cover plate 14 is fixedly connected to the outside of the sleeve 12. Both the sleeve 12 and the cover plate 14 are embedded with protective iron plates 13. By setting the protective iron plates 13, the overall strength of the protective sleeve 2 can be enhanced to prevent damage from impacts.

[0021] Please see Figure 4 Both the sleeve 12 and the cover plate 14 are made of polypropylene, which improves the corrosion resistance and wear resistance of the protective sleeve 2. The protective sleeve 2 can be reused. The inner side of the cover plate 14 is glued with a rubber buffer pad 15. By setting the rubber buffer pad 15, damage can be prevented when foreign objects hit the two ends of the pipe pile, and the impact force can be effectively reduced.

[0022] Please see Figure 1 and Figure 4 The hook and loop fasteners are divided into barbed hook and loop fasteners 11 and soft hook and loop fasteners 3. The barbed hook and loop fasteners 11 are fixedly connected to the left side of the back side of the elastic strap 5, and the soft hook and loop fasteners 3 are fixedly connected to the front surface of the elastic strap 5. By setting the barbed hook and loop fasteners 11 and the soft hook and loop fasteners 3, the elastic strap 5 can be easily fixed.

[0023] Please see Figure 2 The pipe pile body 1 includes a pile body 9, with pads 7 fixedly connected to the top and bottom of the pile body 9, and protective steel rings 8 fixedly fitted on the top and bottom of the outer surface of the pile body 9.

[0024] In use, after the pipe pile is processed, the protective sleeve 2 is placed on both ends of the pipe pile body 1. After it is fully inserted, the elastic strap 5 is wrapped around the surface of the waterproof cloth strip 4 and pulled tight. Then, the barbed hook and loop fastener 11 is attached to the surface of the soft hook and loop fastener 3. This can tighten the waterproof cloth strip 4 so that it is tightly attached to the surface of the pipe pile body 1, preventing rainwater from flowing into the protective sleeve 2 and contacting the protective steel ring 8. This can protect the protective steel ring 8 from rust. During construction, the protective sleeve 2 can be removed for welding and splicing without the need for personnel to grind and remove rust, reducing the labor intensity of personnel. By setting the limiting slot 6 and the limiting protrusion 10, the two pipe piles can be limited when splicing. The limiting protrusion 10 at one end of one pipe pile is inserted into the limiting slot 6 at one end of the other pipe pile. This can prevent the upper pipe pile from rotating during welding, effectively improving construction efficiency.

[0025] In summary, this new type of precast PHC pipe pile, through the combined use of the pipe pile body 1, protective sleeve 2, soft Velcro 3, waterproof cloth strip 4, elastic strap 5, limiting slot 6, limiting protrusion 10, and barbed Velcro 11, solves the problems of not being able to protect the two ends of the pipe pile from rust, requiring grinding and rust removal before welding, increasing the labor intensity of personnel, and the inconvenience of alignment during connection due to the inability to limit positioning, thus affecting construction efficiency.
