Description

Technical Field

[0001] This utility model relates to the field of precast pile technology, and in particular to insert-type precast piles. Background Technology

[0002] Precast piles have a long history of application. Early wooden piles can be seen as the prototype of precast piles. People sharpened wood and drove it into the ground to support simple building structures. With the advent of the Industrial Revolution and the development of construction technology, precast piles made of cast iron and steel began to appear and were used in some projects with high load-bearing capacity requirements. Advances in modern materials science have provided a solid foundation for insert-type precast piles. The research and application of high-strength concrete and high-performance steel materials have given precast piles higher strength, durability, and corrosion resistance. Insert-type precast piles made of high-strength prestressed concrete can withstand greater loads and reduce pile deformation. The high strength and good toughness of steel ensure that the pile can resist various stresses during the insertion process. The prefabrication of insert-type precast piles can be carried out simultaneously with the preparation work on the construction site, shortening the overall construction cycle. Moreover, its construction speed is fast, and the foundation construction can be completed in a short time, meeting the schedule requirements of modern engineering and improving the economic benefits of the project.

[0003] A search revealed Chinese Patent Publication No. CN220538623U, which discloses an insert-type precast pile foundation, including a steel inner cage frame, a concrete outer pile pipe fixedly connected to the outside of the steel inner cage frame, a high-strength pile tip fixedly connected to the bottom of the pile tip mounting seat, and a hammer-driven support structure to prevent cracking inside the concrete outer pile pipe. This insert-type precast pile foundation consists of an upper steel end plate, a steel inner pile tube, and a lower steel end plate. During use, the pile driver directly hammers downwards onto the upper steel end plate, which transmits the impact downwards through the steel inner pile tube to the lower steel end plate. The concrete outer pile tube, located between the upper and lower steel end plates, sinks simultaneously. The metal frame formed by the upper, inner, and lower steel end plates replaces the concrete outer pile tube in directly bearing the force, reducing the likelihood of cracking and achieving the function of bearing pressure and impact resistance from both top and bottom. This solves the problem of devices lacking this function. However, different engineering projects have vastly different geological conditions. In some areas with complex geological conditions, longer piles are needed to reach a stable bearing layer. The inability to splice precast piles can lead to insufficient pile length, failing to provide adequate bearing capacity, while excessive pile length can cause material waste and construction difficulties. Utility Model Content

Different engineering projects have very different geological conditions. In some areas with complex geological conditions, longer piles are required to reach a stable bearing layer.

Excessive pile length will also cause material waste and construction difficulties.

Connecting blocks are fixedly connected to the right sides of the front and rear ends of the precast pile splice. Two short columns are threaded to the right side of these connecting blocks. The right ends of the short columns engage with the inner walls of the corresponding holes, further enhancing the stability of the structure.

At the same time, it can also enhance the interlocking effect between the pile body and the soil to a certain extent, and improve the stability of the structure.

[0047] Working principle: During splicing, the precast pile splicing component 6 uses the loop fastener 7 on the right side of the precast pile splicing component 6 and the loop groove 3 on the left side of the precast pile tip 1 to achieve initial engagement, which can quickly achieve the initial positioning between precast piles without complicated measurement and calibration processes, saving alignment time during splicing and improving construction speed. Then, the short column 9 is engaged with the hole 5, and the nut 11 is rotated to the side close to the connecting block 4 to achieve a fixing effect, forming a multi-connection structure that can effectively resist various forces on the pile during use, ensuring the stability and reliability of the connection parts. When extension is required, it is only necessary to continue splicing with the precast pile splicing component 6, reducing material waste and additional costs caused by complex connection processes.

It adapts to the minor deformations that occur during the use of the precast pile tip 1, is not prone to cracking, and always maintains a good protective effect. The modified polyurea coating 202 on the upper and lower sides of the precast pile tip 1 has ultra-high strength and good impact resistance, which can resist the collisions and friction caused by external forces to the upper and lower sides of the precast pile tip 1, protecting the integrity of the structure. The stirrups 203 on the inner side of the precast pile tip 1 enable the high-strength concrete 204 to better exert its mechanical properties under pressure, enhancing the overall load-bearing capacity of the precast pile tip 1 and the precast pile splice 6. The epoxy coal tar coating 205 on the front and rear sides of the pile splice 6 has good resistance to acid, alkali and salt chemicals, and can protect the precast pile tip 1 from corrosion in soil with corrosive media. The zinc-rich primer coating 206 on the upper and lower sides of the precast pile splice 6 provides a stable foundation for the subsequent protective layer, enhances the reliability of the overall protection system, and fundamentally prevents the precast pile splice 6 from deteriorating in structural performance due to rust, ensuring the strength and stability of the splice. The stirrups 207 and high-strength concrete 208 on the inner side of the precast pile splice 6 can ensure accurate positioning during concrete pouring and use, so that the stirrups 207 can fully exert their tensile strength and work together with the concrete to improve the overall mechanical properties of the component.
