Detailed Implementation

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a building foundation reinforcement pile, such as Figure 1-4 As shown, the foundation reinforcement pile includes: a fixed pile 1 with an installation cavity 2; a through-hole 3, which is located on the side of the fixed pile 1 and connects to the installation cavity 2; a locking block 4, which is slidably installed in the through-hole 3; a connecting block 5, which is fixedly installed on the locking block 4 and slides in contact with the inner wall of the installation cavity 2; a sealing membrane 6, which is fixedly installed on the through-hole 3; a pushing block 7, which is slidably installed in the fixed pile 1 and extends into the installation cavity 2 to contact the connecting block 5, for pushing the locking block 4 to extend out of the installation cavity 2; a pushing rod 8, which is slidably installed in the fixed pile 1 and contacts the pushing block 7; and an extension mechanism, which is provided in the fixed pile 1 to drive the pushing rod 8 to push the pushing block 7 downward.

[0022] In this embodiment, the fixed pile 1 serves as the main structure of the entire building foundation reinforcement pile. Its internal installation cavity 2 provides installation space for other components, acting as the foundational support for the entire device. This allows each component to work collaboratively within the cavity to achieve the foundation reinforcement function. The opening 3 provides a channel for the sliding installation of the locking block 4, enabling it to extend or retract from the installation cavity 2 at specific positions. This alters the interaction between the reinforcement pile and the surrounding soil, enhancing the pile's stability. When the locking block 4 is pushed out of the installation cavity 2 by the pushing block 7, it embeds itself into the surrounding soil. By increasing the contact area and friction with the soil, it effectively improves the pile's pull-out resistance, enhancing its fixation in the soil and overcoming the problem of traditional foundation reinforcement piles relying solely on friction to limit upward movement from the soil layer and having limited pull-out resistance. The connecting block 5 ensures the sliding stability of the locking block 4 within the opening 3, allowing it to extend accurately. The sliding contact between the connecting block 5 and the inner wall of the installation cavity 2 also provides guidance, ensuring the correct direction of movement of the locking block 4 and facilitating its better embedding into the soil. The sealing membrane 6 prevents soil and moisture from entering the installation cavity 2, protecting the components inside from external environmental corrosion and extending their service life. Simultaneously, it is punctured when the connecting block 5 receives driving force, ensuring the stability and reliability of the entire reinforced pile device during long-term use. The jacking block 7 transmits the driving force of the extension mechanism, enabling the locking block 4 to extend, thereby changing the interaction between the reinforced pile and the soil and enhancing the stability of the reinforced pile. The jacking rod 8, as the connecting component between the extension mechanism and the jacking block 7, transmits the driving force of the extension mechanism to the jacking block 7, allowing the jacking block 7 to smoothly push the locking block 4, realizing the transformation and optimization of the reinforced pile's function. Through the operation of the extension mechanism, the locking block 4 extends, thereby enhancing the bonding ability between the reinforced pile and the soil, improving the pull-out resistance and stability of the reinforced pile, and solving the problems of insufficient stability and instability after long-term use of traditional foundation reinforced piles.

[0023] In a further preferred embodiment of this utility model, the extension mechanism includes a positioning block 9, a screw 10, a connecting groove 11, and a rectangular groove 12. The positioning block 9 is rotatably installed in the fixed pile 1. The screw 10 is fixedly installed at the bottom of the positioning block 9 and is threaded into the push rod 8. The connecting groove 11 is opened on the fixed pile 1. The rectangular groove 12 is fixedly installed at the top of the positioning block 9 and is disposed in the connecting groove 11.

[0024] In this embodiment, the rotation of the positioning block 9 drives the screw 10 to rotate, thus providing a power source for the up-and-down movement of the push rod 8. The rotation of the positioning block 9 enables the extension mechanism to drive the push rod 8, thereby controlling the extension and retraction of the locking block 4. This enhances the adjustability of the interaction between the reinforced pile and the soil, improving the adaptability and stability of the reinforced pile under different working conditions. This threaded transmission method features high transmission accuracy and good self-locking, accurately controlling the movement distance of the push rod 8, thereby precisely controlling the extension length of the locking block 4, making the bond between the reinforced pile and the soil tighter and more stable, effectively improving the pull-out resistance of the reinforced pile. The connecting groove 11 provides a channel for the components that drive the extension mechanism. By connecting the drive mechanism to the rectangular groove 12, the positioning block 9 can be driven to rotate, thus providing the necessary structural support for the extension and retraction of the locking block 4. The design of the rectangular groove 12 facilitates connection with an external drive device. The operator can use an external drive device to act on the rectangular groove 12 to drive the positioning block 9 to rotate, thereby operating the extension mechanism. This design makes the installation and use of reinforced piles more convenient, and allows for quick adjustment of the state of the locking block 4 according to actual conditions, improving construction efficiency and further enhancing the applicability and stability of reinforced piles in different engineering scenarios.

[0025] In a further preferred embodiment of the present invention, the push rod 8 is composed of a pressure block and a slide rod, the pressure block is in contact with the push block 7, the slide rod is threadedly connected to the screw 10, and the slide rod is rectangular.

[0026] In this embodiment, the direct contact design between the pressure block and the jacking block 7 ensures effective force transmission, improves the efficiency and reliability of the entire transmission process, ensures that the locking block 4 can extend accurately, and enhances the bonding ability between the reinforced pile and the soil. Because the sliding rod is rectangular, this design increases the contact area between the sliding rod and the inner wall of the fixed pile 1 or other guiding components, improving the stability of the sliding rod during sliding and preventing rotation during movement, ensuring that the jacking rod 8 can only move up and down along the axial direction. Furthermore, the threaded connection between the rectangular sliding rod and the screw 10 is tighter, enabling it to withstand greater force and torque, thus improving the load-bearing capacity and operational reliability of the entire extension mechanism. When the extension mechanism is working, the sliding rod, through threaded transmission with the screw 10, converts the rotation of the positioning block 9 into its own up and down movement, thereby driving the pressure block to push the jacking block 7 and the locking block 4, achieving the adjustment of the reinforced pile function.

[0027] In a further preferred embodiment of the present invention, a limiting groove 13 is provided in the fixed pile 1, and a guide block 14 is fixedly installed on one side of the jacking block 7, and the guide block 14 is slidably connected to the limiting groove 13.

[0028] In this embodiment, the limiting groove 13 provides a sliding track for the guide block 14, restricting the guide block 14 to slide only along the direction of the limiting groove 13, thereby ensuring the accurate and stable movement direction of the jacking block 7 within the fixed pile 1. This limiting effect prevents the jacking block 7 from deviating or wobbling during movement, ensuring that the jacking block 7 can accurately push the locking block 4 out or retract into the mounting cavity 2, improving the reliability and stability of the reinforcement pile operation. The guide block 14 serves to guide and support the jacking block 7 during movement. The sliding contact between the guide block 14 and the limiting groove 13 also reduces the friction force during the movement of the jacking block 7, making the movement of the jacking block 7 smoother and improving the working efficiency of the entire extension mechanism. At the same time, the setting of the guide block 14 also enhances the structural stability of the jacking block 7, preventing it from deforming or being damaged during stress.

[0029] In a further preferred embodiment of the present invention, a storage groove 15 is provided on the outer wall of the fixed pile 1, a movable block 16 is hinged in the storage groove 15, a protrusion 17 is fixedly installed on the movable block 16, and the protrusion 17 extends to the outside of the storage groove 15.

[0030] In this embodiment, when the fixed pile 1 is buried, the movable block 16 does not need to function. It is compressed by the soil and stored within the storage groove 15, reducing space occupation and providing some protection against erosion and damage from the external environment. When the fixed pile 1 is subjected to external force and moves upward, the movable block 16 rotates out of the storage groove 15, increasing the contact with the soil and making the reinforced pile structure more compact and rational, thus improving space utilization. The protrusion 17 increases the contact area and friction between the reinforced pile and the soil, further improving the pull-out resistance and stability of the reinforced pile. Similar to the function of the locking block 4, but with a different placement and function, the protrusion 17 strengthens the bond with the soil from the outside, complementing the internal strengthening bond of the locking block 4, and jointly improving the working performance of the reinforced pile under various working conditions.

[0031] In a further preferred embodiment of the present invention, a limiting block 18 for limiting the rotation angle of the movable block 16 is fixedly installed on the movable block 16.

[0032] In this embodiment, as the movable block 16 rotates around the hinge point, the limiting block 18 contacts the inner wall of the receiving groove 15, thereby preventing the movable block 16 from continuing to rotate and limiting its rotation angle within a certain range. This limiting design ensures that the movable block 16 can accurately reach the required working position when rotating, ensuring that the protrusion 17 can function in the appropriate position and enhancing the bonding ability between the reinforced pile and the soil. At the same time, the limiting block 18 also improves the stability and controllability of the movement of the movable block 16, making the reinforced pile more reliable during use.

[0033] In a further preferred embodiment of the present invention, both the protrusion 17 and the limiting block 18 are configured as barbs, the protrusion 17 is disposed above the limiting block 18, and its volume is larger than that of the limiting block 18.

[0034] In this embodiment, the shape of the barb allows the protrusion 17 to more firmly hook onto the soil when subjected to upward pulling force, while simultaneously pulling the movable block 16 out of the receiving groove 15, increasing the mechanical interlocking force between the reinforced pile and the soil, thereby significantly improving the pull-out resistance of the reinforced pile. Furthermore, the protrusion 17 is positioned above the limiting block 18 and is larger in volume than the limiting block 18; this arrangement allows the protrusion 17 to exert a greater range of action when interacting with the soil. The arrangement of the limiting block 18 and the protrusion 17 makes the descent of the fixed pile 1 smoother, reducing its descent resistance.

[0035] In summary, compared with related technologies, this foundation reinforcement pile device, through a series of innovative designs, significantly enhances the overall stability and pull-out resistance of foundation reinforcement piles. The various components work collaboratively, from the internal retaining blocks extending to strengthen soil bonding, to the external movable blocks and protrusions assisting in fixation, and the limiting structure ensuring precise movement, comprehensively improving the adaptability and reliability of the reinforcement piles under different working conditions. This integrated design not only solves the problems of limited pull-out resistance and insufficient stability after long-term use of traditional foundation reinforcement piles, but also improves construction efficiency and extends service life through optimized structure and added functions, providing more stable and reliable foundation support for buildings or ground engineering projects, demonstrating significant beneficial effects and practical application value.
