[0038] Hereinafter, the present application will be further described in conjunction with specific embodiments, and it should be noted that the following described embodiments or technical features can be combined arbitrarily to form new embodiments without conflict.

[0039] In the description of the present application, it should be noted that for orientation words, such as terms "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation and positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0040] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0041] One aspect of the present application provides a self-measuring force anchor pile, such as Figures 1 to 9As shown, one preferred embodiment includes an anchor pile body 100, a pile driver, a force measuring device 200, and a pile puller 3. The force measuring device 200 is fixedly mounted on the anchor pile body 100, so that the force measuring device 200 can be driven into the ground together with the anchor pile body 100 by the pile driver. During the process of the anchor pile body 100 being buried in the ground, the force measuring device 200 can detect the retaining force exerted on the anchor pile body 100 to ensure that the buried anchor pile body 100 meets the use requirements. When it is necessary to pull out the pile, the pile puller 3 can cooperate with the end of the anchor pile body 100 that is not buried in the ground, so that the pile puller 3 can be operated manually or mechanically to pull out the anchor pile body 100 together with the force measuring device 200 in a direction perpendicular to the ground, thereby ensuring the structural safety of the force measuring device 200 during the pile pulling process.

[0042] It is understood that the structure of the force measuring device 200 is a well-known technology in the art. For example, the publication "A Self-Testing Pile Anchor" with publication number CN114753706A discloses a force measuring device consisting of a measuring mechanism, a force-bearing component, and a force-measuring component. Furthermore, pile drivers are also well-known technology to those skilled in the art. Common pile drivers include diesel pile drivers, gasoline pile drivers, and electric pile drivers. Therefore, when burying a pile, the tip of the anchor body 100 can be first inserted into the ground, and then the pile driver can be aligned with the other end of the anchor body 100 to automatically hammer the pile. Compared to traditional manual hammering methods, this can effectively reduce labor intensity.

[0043] It is also understandable that when using the traditional side-knocking method to pull piles, the construction workers' hammering with a sledgehammer can easily cause vibration shocks to the anchor pile body 100 and the force measuring device 200. Large vibration shocks can easily damage the structure of the force measuring device 200. Large vibration shocks may also cause the force measuring system of the force measuring device 200 to become disordered, thereby causing inaccurate measurement of the retaining force by the force measuring device 200. However, in the present application, by providing a pile puller 3, the anchor pile body 100 and the force measuring device 200 can be continuously and smoothly pulled out in a direction perpendicular to the ground during the pile pulling process. Compared with the traditional side-knocking method, the present application does not cause vibration shocks to the anchor pile body 100, thereby ensuring the accuracy, safety, and non-destructiveness of the pile pulling process.

[0044] In this embodiment, Figure 1 as well as Figures 6 to 9 As shown, the pile puller 3 includes a lifting device 31 and a pile pulling hole plate 32. The output end of the lifting device 31 can be connected to the anchor pile body 100 through the pile pulling hole plate 32, so that when the lifting device 31 pulls up the anchor pile body 100, the position of the pile pulling hole plate 32 can be adjusted to increase the pile pulling stroke.

[0045] It will be appreciated that the structure of the lifting device 31 is well known to those skilled in the art. Common lifting devices 31 include hydraulic lifting devices, pneumatic lifting devices, and motor lifting devices. To facilitate the subsequent description, the lifting device 31 in this embodiment is preferably a hydraulic lifting device. Common hydraulic lifting devices include hydraulic jacks, which have manual and electric operation modes. Because anchor piles are often used in field construction, hydraulic jacks are generally manually operated.

[0046] Specifically, such as Figure 3 As shown, you can simply purchase a commercially available hydraulic jack and remove the cap from its adjusting rod, leaving only the equal-diameter threaded rod for connection to the pile extraction hole plate 32. After connecting the pile extraction hole plate 32 to the hydraulic jack, you can pull out the anchor pile body 100 by driving the hydraulic handle. Compared to traditional side-knocking methods, this method significantly improves the efficiency of pulling out the anchor pile body 100. Furthermore, the lever formed by the hydraulic handle during the pile extraction process effectively saves driving force, thereby reducing the labor intensity of construction personnel.

[0047] In this embodiment, there are multiple ways to connect the pile extraction hole plate 32 with the lifting device 31 and the anchor pile body 100, including but not limited to the following two.

[0048] Connection method 1: Figure 4 and Figures 6 to 9 As shown, the lifting device 31 can be detachably fixedly connected to the pile extraction hole plate 32 through the output end. The pile extraction hole plate 32 is parallel to the anchor pile body 100 and is provided with a plurality of insertion holes 320 evenly distributed along the extension direction. The anchor pile body 100 is connected to the insertion holes 320 at different positions on the pile extraction hole plate 32 to adjust the pile extraction stroke.

[0049] Connection method 2: The anchor pile body 100 and the pile extraction hole plate 32 are detachably fixedly connected. The pile extraction hole plate 32 is parallel to the anchor pile body 100 and is provided with multiple sockets 320 evenly distributed along the extension direction. The lifting device 31 can connect to the sockets 320 at different positions through the output end to adjust the pile extraction stroke.

[0050] It is understood that, with the aforementioned connection method 1, the connection position between the pile extraction hole plate 32 and the lifting device 31 remains unchanged during the pile extraction process of the anchor pile body 100. As the height of the anchor pile body 100 increases during the pile extraction process, the anchor pile body 100 can adjust the pile extraction stroke by connecting to the insertion holes 320 at different positions on the pile extraction hole plate 32.

[0051] With the second connection method described above, the connection position between the pile extraction hole plate 32 and the pile body 100 remains unchanged during pile extraction. As the pile body 100 increases in height during extraction, the lifting device 31 can adjust the pile extraction stroke by connecting to different sockets 320 on the pile extraction hole plate 32. The output end of the hydraulic jack used in the lifting device 31 can be threadedly connected to a support plate to connect to the corresponding socket 320.

[0052] Specifically, such as Figure 4 and Figures 6 to 9 As shown, a connection seat 321 is provided on one side of the pile extraction hole plate 32. In the first connection method described above, the lifting device 31 can be detachably connected to the connection seat 321 of the pile extraction hole plate 32 via the output end; in the second connection method described above, the anchor pile body 100 can be detachably connected to the connection seat 321 of the pile extraction hole plate 32 via the end not buried in the ground.

[0053] The connecting seat 321 is close to one end of the pile pulling hole plate 32 so that the pile pulling stroke can be further increased by turning the direction of the pile pulling hole plate 32 .

[0054] It is understood that because the connection base 321 is positioned toward one end of the pile extraction hole plate 32, there are two ways to adjust the pile extraction stroke during pile extraction of the anchor pile body 100. One is the aforementioned connection method 1 and connection method 2. The other is to rotate the pile extraction hole plate 32 and then reconnect the connection base 321. The distance from the connection base 321 to the center of the pile extraction hole plate 32 can be set as X. By rotating the pile extraction hole plate 32, the maximum pile extraction stroke for the anchor pile body 100 can be increased to 2X.

[0055] In this embodiment, Figure 2 as well as Figures 6 to 9 As shown, a pull ring 110 is provided on one side of the end of the anchor pile body 100 that is not buried in the ground, and the anchor pile body 100 can be detachably connected to the pile extraction hole plate 32 through the pull ring 110 .

[0056] Specifically, taking the above-mentioned connection method 1 as an example, Figures 6 to 9 As shown, when pulling out a pile, the lifting device 31 is detachably threadedly connected to the connecting seat 321 of the pile pulling hole plate 32 through the threaded rod at the output end, and the anchor pile body 100 is aligned with the insertion hole 320 at the corresponding position on the pile pulling hole plate 32 through the pull ring 110, and then the pull ring 110 and the insertion hole 320 are plugged into each other through the connecting pin.

[0057] In this embodiment, Figure 4 as well as Figures 6 to 9As shown, a guide plate 322 is provided on one side of the pile extraction hole plate 32 close to the lifting device 31. During the pile extraction process, the guide plate 322 can fit the lifting device 31, thereby ensuring that the anchor pile body 100 and the force measuring device 200 are pulled out in a direction perpendicular to the ground.

[0058] It is understood that, because the connection positions of the pile extraction hole plate 32 with the anchor pile body 100 and the lifting device 31 are misaligned in the pile extraction direction, the anchor pile body 100 is easily deflected when the lifting device 31 drives the anchor pile body 100 to extract the pile through the pile extraction hole plate 32, thereby increasing the pile extraction resistance of the anchor pile body 100. The pile extraction hole plate 32 is provided with a guide plate 322, which can be respectively fitted with the anchor pile body 100 and the lifting device 31. During the pile extraction process, the deflection tendency of the anchor pile body 100 is suppressed by the lifting device 31, thereby ensuring that the anchor pile body 100 can only be extracted in a direction perpendicular to the ground, which can effectively reduce the pile extraction resistance of the anchor pile body 100.

[0059] Another aspect of the present application provides a method for operating a self-testing anchor pile, such as Figures 6 to 9 As shown, one of the preferred embodiments includes the following steps:

[0060] S100: Piling, align the tip of the anchor pile body with the ground, then push the pile driver to the other end of the anchor pile body, and start the pile driver to automatically drive the anchor pile body together with the force measuring device into the ground.

[0061] S200 : Preparation for pile extraction: placing the lifting device 31 on the ground, and then connecting the lifting device 31 to the end of the anchor pile body 100 exposed to the ground through the pile extraction hole plate 32 .

[0062] S300: pulling out the pile, operating the lifting device 31 to drive the pile pulling hole plate 32 to drive the anchor pile body 100 and the force measuring device 200 to rise synchronously perpendicular to the ground direction until the anchor pile body 100 is completely pulled out.

[0063] In this embodiment, in step S200, the pile extraction hole plate 32 is detachably connected to the pull ring 110 of the anchor pile body 100 at the first end, and the pile extraction hole plate 32 is detachably connected to the output end of the lifting device 31 at the position close to the second end.

[0064] In this embodiment, Figures 6 to 9 As shown, step S300 includes the following specific processes:

[0065] S310: The lifting device 31 drives the pile extraction hole plate 32 through the lifting of the output end, driving the anchor pile body 100 and the force measuring device 200 to rise synchronously for a lifting stroke.

[0066] S320: The output end of the lifting device 31 is reset, and at the same time, the second end of the pile-pulling hole plate 32 is adjusted to be close to the pull ring 110 of the anchor pile body 100 and connected.

[0067] S330: The lifting device 31 again pulls the anchor pile body 100 and the force measuring device 200 upward synchronously through a lifting stroke through the pile pulling hole plate 32 .

[0068] S340: Repeat steps S320 and S330 until the anchor pile body 100 and the force measuring device 200 are pulled out; if the second end of the pile extraction hole plate 32 is connected to the pull ring 110 of the anchor pile body 100 and the anchor pile body 100 is not pulled out after the lifting stroke is completed, proceed to step S350.

[0069] S350: Turn the pile extraction hole plate 32 around and reconnect it to the anchor pile body 100 and the lifting device 31 respectively. Then the lifting device 31 can again drive the anchor pile body 100 and the force measuring device 200 to rise through the pile extraction hole plate 32 until the anchor pile body 100 and the force measuring device 200 are pulled out.

[0070] For ease of understanding, the specific working process of the self-testing anchor pile is described in detail by adopting the above-mentioned connection method.

[0071] When driving a pile, the tip of the anchor pile body 100 is inserted into the ground so that the anchor pile body 100 can stand stably on the ground. Then, the output end of the pile driver is pressed against the upper end of the anchor pile body 100. The pile driver is then turned on and automatically drives the anchor pile body 100 and the force measuring device 200 into the ground through its own rapid vibration and hammering.

[0072] After the piling is completed, Figure 5 As shown, the anchor pile body 100 together with the force measuring device 200 can be buried in the ground in a direction inclined to the ground or perpendicular to the ground.

[0073] When pile extraction is required, Figures 6 to 8 As shown, the lifting device 31 is placed on the ground near one side of the anchor pile body 100, and then the connecting seat 321 of the pile extraction hole plate 32 is connected to the output end of the lifting device 31. At the same time, the insertion hole 320 at the first end of the bottom of the pile extraction hole plate 32 is connected to the pull ring 110 of the anchor pile body 100 via a connecting pin. At this time, the connecting seat 321 is close to the second end of the top of the pile extraction hole plate 32.

[0074] Then, the first process is carried out: the construction personnel operate the lifting device 31 through the hydraulic handle on the lifting device 31 to drive the anchor pile body 100 to be lifted perpendicularly to the ground through the pile extraction hole plate 32 until the lifting device 31 completes a lifting stroke.

[0075] Next, the second step begins: the connecting pin is pulled out to separate the pile extraction hole plate 32 and the anchor pile body 100, and the lifting device 31 is reset. After the lifting device 31 is reset, the pull ring 110 of the anchor pile body 100 is reconnected to the corresponding socket 320 of the pile extraction hole plate 32 via the connecting pin. The construction worker then uses the hydraulic handle to operate the lifting device 31 again, driving the anchor pile body 100 through the pile extraction hole plate 32 to raise the lifting stroke.

[0076] Then, the second process is repeated until the anchor pile body 100 is pulled out. Alternatively, after the insertion hole 320 at the second end of the pile extraction hole plate 32 is connected to the anchor pile body 100 and the corresponding lifting stroke is completed, if the anchor pile body 100 is still not pulled out, the pile extraction hole plate 32 can be rotated so that the connecting seat 321 is close to the ground and connected to the lifting device 31. Then, the construction worker can operate the lifting device 31 again using the hydraulic handle to drive the anchor pile body 100 to continue lifting the anchor pile body 100 to a maximum stroke of 2X, so as to ensure that the anchor pile body 100 and the force measuring device 200 can be smoothly pulled out.

[0077] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought.
