DETAILED DESCRIPTION

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a concrete hollow square pile, such as Figure 1-4 As shown, the concrete hollow square pile comprises: a spliced ​​hollow square pile body 1 prefabricated with concrete material 2, a plurality of vertical bars 3 and a plurality of ring bars 4; a square hole 5 arranged on the hollow square pile body 1; a protrusion 6 arranged at the top of the hollow square pile body 1 for docking; a recessed portion 16 arranged at the bottom of the hollow square pile body 1 and matched with the protrusion 6; a detachable plug 7 assembled at the bottom of the hollow square pile body 1 for blocking the square hole 5; a limiting sleeve 8 fixed on the bottom end of the vertical bar 3 for docking and limiting; and a limiting clamping mechanism arranged on the limiting sleeve 8 for clamping and limiting.

[0022] It should be noted that the many inconveniences in the docking of traditional concrete hollow square piles do bring considerable challenges to the construction; the following is a further explanation of these problems: First, the difficulty in controlling the docking accuracy is a significant problem. Since the traditional docking method often relies on manual operation and simple positioning devices, the error during docking is large and the accurate docking between the pile bodies cannot be guaranteed, which not only affects the structural stability of the entire project, but may also cause safety hazards due to inaccurate docking; secondly, low docking efficiency is also a problem with traditional concrete hollow square piles. Traditional docking methods often require a lot of time and manpower, and repeated adjustments and calibrations to barely meet the docking requirements. This not only increases construction costs, but also seriously delays the progress of the project, causing considerable economic losses to the construction unit. In addition, insufficient stability after docking is also a potential problem with traditional concrete hollow square piles. Due to the low docking accuracy, the connection between the pile bodies is often not tight enough and is easily affected by external factors such as loose soil and vibration, which causes the pile bodies to loosen or shift, which not only affects the long-term stability of the project, but also may pose a potential threat to the quality of the project. In summary, these problems existing in the docking of traditional concrete hollow square piles not only affect the construction progress and project quality, but also increase the difficulty and cost of construction. Therefore, there is an urgent need for a new type of concrete hollow square pile and its docking technology to solve these problems.

[0023] In this embodiment, the concrete hollow square pile is mainly prefabricated with concrete material 2, a plurality of vertical bars 3 and a plurality of ring bars 4 to form a spliced ​​hollow square pile body 1. This design not only enhances the overall strength and stability of the pile body, but also improves production efficiency through prefabrication; secondly, the hollow square pile body 1 is provided with square holes 5, which not only reduces the weight of the pile body and reduces production costs, but also helps the pile body to penetrate and drain in the soil, thereby increasing the service life of the pile body; at the top of the hollow square pile body 1, a protrusion 6 for docking is provided, and at its bottom, a recessed portion 16 adapted to the protrusion 6 is provided. This design makes the docking between pile bodies more accurate and convenient, greatly improves the docking accuracy, and reduces the error during docking; in addition, in order to block the square hole 5, the present embodiment also assembles a detachable plug 7 at the bottom end of the hollow square pile body 1; this plug 7 is not only convenient for disassembly and installation, but also can effectively prevent soil or other impurities from entering the square hole 5, ensuring the internal cleanliness and normal use of the pile body; more importantly, the present embodiment also fixes a limit sleeve 8 for docking limit on the bottom end of the vertical rib 3, and provides a limit clamping mechanism for clamping limit on the limit sleeve 8; this design innovatively solves the problem of insufficient stability during docking of traditional pile bodies, and through the coordinated use of the limit sleeve 8 and the limit clamping mechanism, it can ensure that the pile body is tightly connected during the docking process, and is not easily affected by external factors and becomes loose or displaced.

[0024] In a further preferred embodiment of the utility model, the fixing mechanism includes: a plurality of sliding rods 9 fixed in the limiting sleeve 8; a sleeve plate 10 slidably sleeved on the sliding rods 9; a clamping block 11 fixed on the sleeve plate 10 for fixing the vertical ribs 3; and a spring 12 sleeved on the sliding rods 9.

[0025] In this embodiment, the clamping block 11 is mainly used to clamp the vertical ribs 3, which means that the shape, size and material of the clamping block 11 have been carefully designed to ensure that it can closely match the vertical ribs 3 to achieve a firm connection between the pile bodies; when the two pile bodies are docked, the vertical ribs 3 of the protrusion 6 will be inserted into the recessed portion 16 and contact the clamping block 11. As the pile bodies are further docked, the clamping block 11 will be squeezed by the vertical ribs 3, thereby driving the sleeve plate 10 to slide on the slide rod 9 and compressing the spring 12. When the docking is completed, the restoring force of the spring 12 will return the sleeve plate 10 and the clamping block 11 to the initial position, at which time the clamping block 11 will tightly clamp the vertical ribs 3 to prevent loosening or displacement between the pile bodies.

[0026] In a further preferred embodiment of the utility model, a plug plate 13 is fixedly installed on the top of the plug 7, and the plug plate 13 is adapted to the square hole 5. A plurality of assembly rods 14 are symmetrically fixedly installed on the bottom of the plug 7, and a pointed cone 15 is fixedly installed on the bottom end of each of the assembly rods 14.

[0027] In this embodiment, a plug-in board 13 is fixedly installed on the top of the plug 7. This design enables the plug-in board 13 to be compatible with the square hole 5; in actual use, when the plug 7 needs to be assembled to the bottom end of the hollow square pile body 1 to block the square hole 5, it is only necessary to align the plug-in board 13 with the square hole 5 and then push it downward to easily achieve the installation of the plug 7; this plug-in assembly method is not only convenient and fast, but also firmly assembled and not easy to fall off; secondly, a number of assembly rods 14 are symmetrically fixedly installed at the bottom of the plug 7; and a pointed cone 15 is also fixedly installed on the bottom end of these assembly rods 14. Such a design enables the plug 7 to utilize the sharp characteristics of the pointed cone 15 to easily penetrate into the soil or other media during the assembly process, thereby enhancing the connection between the plug 7 and the surrounding environment and improving the stability of the overall structure; at the same time, the symmetrical arrangement of the assembly rod 14 also ensures that the plug 7 can be evenly distributed when subjected to force, avoiding structural damage caused by uneven force; the design and use of this plug 7 brings significant beneficial effects; first, the matching design of the plug plate 13 and the square hole 5 makes the installation of the plug 7 more convenient and quick, and improves the construction efficiency. Secondly, the setting of the assembly rod 14 and the pointed cone 15 not only enhances the connection between the plug 7 and the surrounding environment and improves the stability of the overall structure, but also enables the plug 7 to be evenly distributed when subjected to force, thereby extending its service life.

[0028] In a further preferred embodiment of the utility model, the outer surface of the hollow square pile body 1 is provided with an anti-slip texture, the inner wall of the square hole 5 is provided with a waterproof coating, and the vertical ribs 3 and the ring ribs 4 are made of corrosion-resistant materials.

[0029] In this embodiment, the outer surface of the hollow square pile body 1 is provided with an anti-skid texture. This design plays a very important role in actual construction. The anti-skid texture can increase the friction coefficient of the outer surface of the square pile, making the square pile less likely to slide during hoisting, transportation and installation, thereby improving the safety of construction. In addition, the anti-skid texture can also effectively prevent rainwater or mud from accumulating on the surface of the square pile, keeping the square pile clean and dry, which is conducive to extending its service life; secondly, the inner wall of the square hole 5 is provided with a waterproof coating. The provision of the waterproof coating can effectively prevent moisture from penetrating into the interior of the square pile, thereby avoiding problems such as steel bar corrosion and reduced structural strength caused by moisture erosion. This improvement not only improves the durability of the square pile, but also ensures its stable performance under various harsh environmental conditions; finally, the vertical reinforcement 3 and the ring reinforcement 4 are made of corrosion-resistant materials. Traditional steel bars are prone to rust in a humid or corrosive environment, affecting the overall strength and service life of the square pile. The vertical reinforcement 3 and the ring reinforcement 4 made of corrosion-resistant materials can effectively resist the erosion of rust and maintain the structural integrity and stability of the square pile; this improvement not only improves the durability of the square pile, but also reduces the maintenance and replacement costs caused by steel bar corrosion.

[0030] In a further preferred embodiment of the utility model, the mating surfaces of the protrusion 6 and the recessed portion 16 are provided with sealing material, and the sealing material is a weather-resistant silicone sealant. The outer wall of the vertical rib 3 is provided with a card groove, and the card groove is adapted to the card block 11.

[0031] In this embodiment, the butt joint surface of the protrusion 6 and the recessed portion 16 is provided with a sealing material. The main purpose of this design is to enhance the sealing of the butt joint surface, prevent moisture, dust or other impurities from entering the butt joint gap, thereby ensuring that the connection between the pile bodies is tight and stable. In this embodiment, a weather-resistant silicone sealant is specially selected as the sealing material. The silicone sealant has excellent weather resistance and can resist the erosion of natural factors such as sunlight, rain, temperature changes, etc. for a long time, and maintain its good sealing performance. In addition, the silicone sealant also has good adhesion and elasticity, can fit tightly to the docking surface, form a solid sealing layer, and effectively prevent leakage problems on the docking surface; secondly, a card slot is set on the outer wall of the vertical rib 3. This design is to adapt to the card block 11 to achieve precise positioning and firm connection between the pile bodies. During the docking process, the card block 11 can be accurately inserted into the card slot, thereby ensuring the docking accuracy between the protrusion 6 and the recessed portion 16. This card connection method is not only simple and convenient to operate, but also has a firm and reliable connection that is not easy to loosen or shift. At the same time, the design of the card slot and the card block 11 can also withstand a certain external force, maintain the stability between the pile bodies, and ensure the safety and reliability of the entire structure.

[0032] In a further preferred embodiment of the utility model, a lifting hole is provided on the raised portion 6, a reinforcing steel pipe is provided in the lifting hole, and the reinforcing steel pipe is fixed to the lifting hole by welding or threaded connection.

[0033] In the present embodiment, a hoisting hole is provided on the raised portion 6. This design enables the hollow square pile body 1 to be connected to the hoisting equipment through the hoisting hole during the hoisting process, so as to facilitate the hoisting operation. The provision of the hoisting hole not only simplifies the hoisting process, but also improves the construction efficiency, making the installation of the square pile more convenient. Secondly, a reinforced steel pipe is provided in the hoisting hole. The addition of the reinforced steel pipe significantly enhances the load-bearing capacity and stability of the hoisting hole. During the hoisting process, the reinforced steel pipe can withstand a large tensile force, ensuring that the square pile is not easily deformed or damaged during the hoisting process. At the same time, the reinforced steel pipe can also disperse the stress during the hoisting process, reduce the local pressure on the hoisting hole, and further improve the hoisting safety of the square pile. In addition, the reinforced steel pipe is fixed to the hoisting hole by welding or threaded connection. This connection method is both firm and reliable, and can ensure that the reinforced steel pipe will not fall off or loosen during the hoisting process. The welding method has the advantages of high connection strength and good sealing, while the threaded connection method has the characteristics of easy disassembly and reusability. According to specific construction requirements, you can choose the appropriate connection method.

[0034] In a further preferred embodiment of the utility model, a soil breaking cone is provided at the bottom end of the plug 7 , the plug plate 13 is made of high-strength rubber material, and the outer wall of the plug plate 13 fits with the inner wall of the square hole 5 .

[0035] In this embodiment, a soil-breaking cone is provided at the bottom end of the plug 7. This design allows the plug 7 to be inserted into the soil more easily, reduces the difficulty of installation, and improves the construction efficiency. The sharp shape of the soil-breaking cone can effectively break the soil, so that the plug 7 can reach the predetermined installation depth more quickly. At the same time, the soil-breaking cone can also enhance the connection between the plug 7 and the soil, and improve the stability of the overall structure. Secondly, the plug board 13 is made of high-strength rubber material. This material not only has excellent elasticity and wear resistance, but also can play a buffering role when impacted, protecting the edge of the square hole 5 from damage. At the same time, the high-strength rubber material also has good sealing performance, which can ensure the close fit between the plug board 13 and the square hole 5, and prevent moisture or other impurities from entering the pile body. In addition, the outer wall of the plug board 13 is in close contact with the inner wall of the square hole 5. This design can not only enhance the connection between the plug 7 and the pile body, but also improve the sealing of the overall structure, and prevent moisture or other impurities from penetrating from the interface. The tight-fitting design can also reduce the risk of the interface loosening or falling off due to vibration or external force, ensuring the stability and durability of the plug 7.

[0036] To sum up, the concrete hollow square piles provided by this technical solution, through optimized design and innovative structure, solve the problems of difficult to control docking accuracy, low docking efficiency and insufficient stability after docking during docking of traditional piles. This not only improves the construction progress and project quality, but also reduces the construction difficulty and cost, providing a more reliable and efficient solution for engineering construction.

[0037] Compared with the relevant technology, the prefabricated splicing design and the setting of the square hole 5 not only improve the production efficiency and reduce the weight of the pile body, but also enhance the drainage performance, thereby extending the service life; secondly, the precise docking design and the use of the detachable plug 7 make the pile body docking more convenient and accurate, improve the construction efficiency, and effectively prevent impurities from entering the pile body; finally, through the application of anti-slip texture, waterproof coating and corrosion-resistant materials, the safety, stability and durability of the square pile are enhanced, and the maintenance and replacement costs are reduced.
