Description

Technical Field

[0001] This application relates to the field of infrastructure construction, and in particular to a high-efficiency force-shaping irregular pile. Background Technology

[0002] With the rapid development of infrastructure construction, pile foundations, as an efficient form of foundation treatment, are widely used in engineering projects dealing with complex geological conditions due to their excellent bearing capacity, construction adaptability, and long-term stability. Static pressure pile driving, with its smooth construction process, low noise, and absence of mechanical impact, has significant environmental advantages in foundation construction in environmentally sensitive areas and densely populated urban areas. However, the static pressure penetration process inevitably induces soil disturbance, which is particularly significant in soft soil foundations and other complex geological conditions. This disturbance often leads to problems such as surface heave, lateral displacement, and settlement of adjacent structures, seriously affecting project safety and construction efficiency.

[0003] Existing technologies for reducing disturbance caused by the interaction between piles and soil typically employ methods such as increasing pile spacing, improving pile design, or soil reinforcement. However, these measures have limitations in projects with limited construction sites or high bearing capacity requirements. Furthermore, some technologies reduce disturbance through pre-drilling or grouting, which partially improves construction results but increases construction complexity and equipment dependence, thus limiting their widespread application.

[0037] First embodiment:

[0038] Please refer to Figure 1 (Refer to) Figures 2 to 5This application provides a high-efficiency force-shaping irregular pile, which focuses on solving key problems such as construction difficulties caused by soil disturbance and insufficient pile bearing capacity during pile driving. At the same time, for the problems of surface deformation and lateral soil displacement in pile driving operations in coastal foundations and densely built urban areas, this application effectively reduces the disturbance to the surrounding environment during construction through geometric structure optimization and mechanical distribution control, while improving the bearing capacity of the pile foundation and meeting the needs of efficient construction under complex geological conditions. It mainly includes PHC pipe piles 1, connecting structure 2, and clamping pile shoe 3 connected in sequence. Its overall design takes into account the efficiency of prefabrication process and the convenience of on-site assembly. Among them, PHC pipe pile 1 includes a connected pile body 6 and a chuck 7. By pre-stressing the steel bars and then pouring concrete, a prestressed PHC pipe pile 1 pile body 6 is formed. The chuck 7 has multiple bolt holes. The main function of the chuck 7 is to stretch the prestressed steel bars. At the same time, the connecting structure 2 includes a first flange plate 8, a second flange plate 9, and a connecting column 10. The first flange plate 8 is detachably connected to the corresponding bolt holes on the chuck 7 by multiple bolts. The two ends of the connecting column 10 are respectively connected between the first flange plate 8 and the second flange plate 9. The clamping pile shoe 3 has multiple bolt holes on the other end adjacent to the connecting structure 2. The second flange plate 9 is connected to the corresponding bolt holes on the other end of the clamping pile shoe 3 by multiple bolts.

[0039] It should be noted that multiple stiffening plates 11 are also connected between the first flange plate 8 and the second flange plate 9, and the multiple stiffening plates 11 are respectively arranged at intervals on the peripheral side wall of the connecting column 10.

[0040] Meanwhile, the clamping shoe 3 is made entirely of high-strength wear-resistant steel. At the end of the clamping shoe 3 furthest from the second flange plate 9, there is a V-shaped clamping groove 4. Multiple wedge-shaped grooves are formed on the surface of the V-shaped clamping groove 4, and each wedge-shaped groove contains a matching wedge block 5. The wedge block 5 engages with the wedge-shaped groove on the clamping shoe 3, and the clamping shoe 3 clamps the foundation soil by applying a pre-tightening force. The wedge block 5 is made of high-strength alloy steel, and its shape matches the wedge-shaped groove, ensuring that the wedge block 5 can be tightly embedded in the wedge-shaped groove. Compared to traditional conical static pressure piles, this application introduces a gradually inclined clamping shoe 3 (interlocking wedge-shaped groove design) in the pile bottom area, and accurately optimizes the penetration force transmission path through mechanical model calculations. The force-component clamping shoe 3 adopts a modular assembly design, is compatible with the prestressed PHC pipe pile 1, facilitates rapid assembly, significantly shortens the construction cycle, and reduces the manufacturing difficulty and transportation cost of precast piles. Meanwhile, this application utilizes a unique "Clamping-Force Transmission Mechanism" to achieve controlled distribution of penetration force. Its interlocking geometric design can centrally capture and compact the soil at the pile bottom, guiding the mechanical force to the deep foundation, effectively reducing lateral displacement of the soil around the pile and suppressing surface heave. Compared with existing technologies, this design significantly improves pile end resistance and overall bearing capacity, making it particularly suitable for complex geological conditions and environmentally sensitive areas. Furthermore, by combining optimized mechanical properties with modular design, this application's high-efficiency force-complementary irregular pile provides an economical, efficient, and low-environmental-impact solution for complex foundations and coastal engineering, meeting the diverse performance requirements of modern engineering technology for pile foundations.

[0041] It should be noted that the opening of the V-shaped clamping groove 4 is 40-70°.

[0042] It should be noted that in deep soft soil foundations, static pressure pile driving is typically used for foundation treatment to accelerate construction progress and reduce the impact on the surrounding environment. However, to meet high bearing capacity requirements, it is often necessary to densely drive PHC pipe piles 1 into the foundation, which generates significant soil disturbance during the pile driving process, thereby weakening the stability and bearing capacity of the pile foundation. The high-efficiency force-redistribution type irregular pile proposed in this application features a unique geometric design for its clamping pile shoe 3. Through a force redistribution mechanism, it adjusts the stress distribution during the penetration of the PHC pipe pile 1, guiding more soil to the deeper foundation and reducing the concentrated distribution of penetration force on the sidewall of the PHC pipe pile 1, effectively reducing the lateral displacement and disturbance of the soil. Simultaneously, this structure enhances the synergistic adaptability between the PHC pipe pile 1 and the soil, strengthens the overall stability of the foundation, and significantly reduces the adverse impact of construction on the surrounding environment.

[0043] It should be noted that multiple bolt holes are pre-drilled on the chuck 7 of the PHC pipe pile 1 to connect with the first flange plate 8. The size and position of these bolt holes have been precisely calculated and designed to ensure the stability and reliability of the connection. To improve the corrosion resistance of the force-shaping clamping shoe 3, its surface is treated with anti-corrosion measures, such as coating, electroplating, or other effective anti-corrosion methods. This anti-corrosion treatment can extend the service life of the force-shaping clamping shoe 3 and reduce maintenance costs.

[0044] Furthermore, while existing pile types (such as XXC piles and wedge piles) offer some improvements to pile foundation construction under specific geological conditions, their capacity enhancement effect is limited in complex geological environments, making it difficult to solve the key technical bottlenecks in pile foundation construction. This application innovatively designs a high-efficiency force-shaping irregular-shaped pile, which, by optimizing the geometry of the pile base, precisely transmits the penetration force to the pile bottom region, significantly improving the compaction effect of the soil at the pile bottom and thus greatly enhancing the pile tip bearing capacity. In addition, by optimizing the interaction mechanism between the PHC pipe pile 1 and the soil, this application significantly improves the long-term stability and service performance of the pile foundation, providing a reliable solution for efficient construction under complex foundation conditions.

[0045] Furthermore, the high-efficiency force-shaping irregular-shaped pile proposed in this application adopts a prefabricated design. The PHC pipe pile 1 is assembled with the clamping pile shoe 3 via a connecting structure 2. On-site assembly of the entire pile foundation is quickly completed using a combination of bolt fastening. Special materials (such as high-density, low-permeability fillers) are used to further stabilize and protect the connection area from corrosion. This innovative design significantly reduces the prefabrication difficulty of irregular-shaped pile foundations and substantially improves construction efficiency. Simultaneously, the combination of the standardized clamping pile shoe 3 with the conventional PHC pipe pile 1 not only simplifies the construction process and reduces the need for specialized equipment but also enhances the flexibility and applicability of pile foundation construction, providing a more economical and rapid solution for large-scale applications.

[0046] After being manufactured in the factory, the PHC pipe pile 1 and the clamping pile shoe 3 are transported to the construction site. Through rapid assembly using the connecting structure 2, bolts, and gaskets, the PHC pipe pile 1 and the clamping pile shoe 3 are firmly connected. Protective material is filled between the first flange plate 8, the second flange plate 9, and the stiffening plate 11 to enhance the corrosion resistance and structural stability of the connecting structure 2. After assembly, the irregularly shaped pile is driven into the foundation using construction equipment. The geometric design of the clamping pile shoe 3 significantly reduces soil disturbance around the pile and improves the bearing capacity of the pile tip. Several reinforcing ribs are provided at the bottom of the clamping pile shoe 3, arranged radially to improve the overall rigidity and bearing capacity of the clamping pile shoe 3. Several stiffening plates 11 are arranged in a ring between the first flange plate 8 and the second flange plate 9 to enhance the bending and torsional resistance of the connecting structure 2. The bolts of the connecting structure 2 are high-strength bolts with an anti-corrosion coating to improve the strength and durability of the connection; elastic gaskets are used to increase the sealing and seismic performance of the connection. The protective material filled between the first flange plate 8, the second flange plate 9, and the stiffening plate 11 is a high-performance anti-corrosion material such as epoxy resin or polyurethane, to effectively prevent corrosion of the connection structure 2. Furthermore, the bottom of the clamping pile shoe 3 can be designed in different shapes according to different geological conditions to adapt to different foundation bearing capacity requirements.

[0047] The tight connection between the PHC pipe pile 1 and the clamping pile shoe 3 significantly enhances the bearing capacity of the pile foundation. The design of the clamping pile shoe 3 ensures effective clamping of the foundation soil, thereby increasing the overall stability of the pile foundation. Simultaneously, the design of the clamping pile shoe 3 simplifies and speeds up the construction process. The shoe structure facilitates easy installation and disassembly, reducing complex operations during construction, thus shortening the construction cycle and lowering labor costs. Furthermore, the design of the clamping pile shoe 3 increases the contact area between the pile foundation and the soil, improving its resistance to overturning. Moreover, the anti-corrosion design of the clamping pile shoe 3 and the connecting structure 2 extends the service life of the pile foundation. Anti-corrosion treatment reduces the risk of corrosion during long-term use, thereby reducing maintenance costs. In addition, the drainage holes and reinforcing ribs in the design effectively reduce soil disturbance and pore water pressure, thus reducing the negative impact of construction on the surrounding environment and improving the overall performance of the pile foundation.

[0048] In summary, this structure, through the sequential connection of PHC pipe piles 1, connecting structure 2, and clamping pile shoe 3, and the design of matching wedge-shaped grooves and wedge blocks 5 on the clamping pile shoe 3, innovatively controls the geometry of the high-efficiency force-shaping irregular-shaped pile and the stress transfer path of the soil during pile driving. It can significantly optimize the soil disturbance distribution during static pressure penetration, reducing surface deformation and lateral movement of the soil around the pile. Simultaneously, this structure optimizes the load transfer mechanism between the pile tip and pile side through the clamping pile shoe 3, not only improving bearing capacity but also demonstrating good adaptability under various complex geological conditions, meeting the diverse needs of modern engineering for high bearing capacity and low-disturbance construction. Furthermore, the structure achieves rapid integration between the pile shoe and the PHC pipe pile 1 through modular design and assembly process, effectively improving construction efficiency and reducing equipment and process complexity. Its environmentally friendly and efficient design features provide a more reliable and economical technical solution for foundation construction under complex geological conditions. Furthermore, this application addresses the disturbance problem caused by the interaction between the pile foundation and the soil during static pressure pile driving by proposing a high-efficiency force-component irregular-shaped pile. This pile type is particularly suitable for soft soil foundations. Through optimized geometric design and the application of innovative materials, it effectively reduces the horizontal displacement of the soil around the pile during penetration, significantly minimizing disturbance to the surrounding soil and existing structures. During construction, this design further optimizes the mechanical response of the soil by adjusting the stress distribution in the pile bottom area of ​​the clamping pile shoe 3, reducing environmental interference and construction risks. In addition, the prefabricated design of the high-efficiency force-component irregular-shaped pile not only improves construction efficiency but also significantly enhances the pile foundation's anti-settlement capacity and bearing capacity, thereby effectively ensuring the long-term stability of the foundation and the safety and reliability of the structure.

[0053] The first stiffening rib 18 and the second stiffening rib 19 are used to enhance the shear strength and overall rigidity of the connecting structure 2. The second connecting plate 13 and the third connecting plate 14 are fastened together by bolts and corresponding round holes on them, along with nuts and washers.

[0054] In this embodiment, the upper surface of the clamping shoe 3 is smooth and has no bolt holes.
