Description

Technical Field

[0001] This utility model relates to an axis adjustment device for horizontal static load testing in pile foundation inspection, and belongs to the field of pile foundation inspection technology. Background Technology

[0002] As is known, the horizontal static load test of a test pile usually involves applying a horizontal force between the test pile and the anchor pile, and the process of applying the horizontal force requires that the horizontal force passes exactly through the core of the test pile and the anchor pile.

[0003] Currently, the existing method for adjusting the axis of the test pile in the horizontal static load test usually involves first determining a direction by visual inspection, and then adjusting the position of the pad by continuously applying and removing pressure, so as to make the horizontal force pass through the core of the test pile and the anchor pile.

[0004] The above-mentioned method of adjusting the axis based on human visual inspection has at least the following important drawbacks: When making a visual inspection, one must stand at a distance to have an overall grasp of the positions of the two piles. After determining the direction, adjusting the pads at close range often results in discrepancies with expectations, leading to both time and effort being wasted and the quality not being guaranteed. Summary of the Invention

[0005] To overcome the above-mentioned shortcomings of the prior art, this utility model provides an axis adjustment device for horizontal static load test in pile foundation testing. This device can help operators quickly find the direction of the horizontal loading force during installation, which can improve efficiency and save costs. It also has the advantages of simple and convenient operation, high test quality and accurate test results.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An axis adjustment device for horizontal static load testing in pile foundation inspection includes:

[0008] A ring pile assembly, comprising a first ring pile member detachably connected to the outer periphery of the test pile and a second ring pile member detachably connected to the outer periphery of the anchor pile; and

[0009] The retractable load-bearing assembly has its two ends fixedly connected to the outside of the first ring pile and the second ring pile respectively and located in the radial direction of both. The retractable load-bearing assembly is configured to place the horizontal force loading assembly.

[0010] As a further optional design of this technical solution, the first ring pile and the second ring pile have the same structure, both of which are adjustable metal cable ties.

[0011] As a further optional design of this technical solution, the adjustable metal cable tie includes a strip of iron, one end of which is provided with a buckle, and the other end is provided with multiple adjustable slots that can be connected with the buckle.

[0012] As a further optional design of this technical solution, the telescopic load-bearing component is a telescopic channel steel, with both ends of the telescopic channel steel welded and fixed to the strip iron plates of the first ring pile and the second ring pile respectively.

[0013] As a further optional design of this technical solution, the retractable load-bearing component includes multiple retractable channel steels that are interlocked with each other, with the ends of the two retractable channel steels located at the beginning and end welded to the first ring pile and the second ring pile respectively.

[0014] As a further optional design of this technical solution, the horizontal force loading assembly includes a jack connected between the test pile and the anchor pile. The jack is connected to the test pile and the anchor pile respectively through a first shim block assembly and a second shim block assembly. The jack, the first shim block assembly and the second shim block assembly are placed together on the telescopic channel steel.

[0015] By utilizing the above technical solution, the present invention provides an axis adjustment device for horizontal static load testing in pile foundation inspection. By setting up an integrated ring pile assembly and a telescopic bearing assembly, the ring pile assembly is first used to connect with the test pile and anchor pile and lock the pile core position. Then, the telescopic bearing assembly is used to carry the horizontal force loading assembly and arrange it on the line connecting the pile cores, thereby ensuring that the direction of force loading is always accurate, simplifying the existing alignment steps, saving manpower and time costs, improving work efficiency, and ensuring high test quality and accuracy of test results.

[0032] Figure 1 and Figure 2 A schematic diagram of a preferred embodiment of the present invention is shown. The diagram illustrates an axis adjustment device 10 for a horizontal static load test in pile foundation inspection, comprising a ring pile assembly 11 and a telescopic load-bearing assembly 12. Wherein:

[0033] The ring pile assembly 11 includes a first ring pile member 111 detachably connected to the outer periphery of the test pile 30 and a second ring pile member 112 detachably connected to the outer periphery of the anchor pile 40; the two ends of the telescopic bearing assembly 12 are respectively fixedly connected to the outside of the first ring pile member 111 and the second ring pile member 112 and are located in the radial direction of both, and the telescopic bearing assembly 12 is configured to place the horizontal force loading assembly 20.

[0034] In specific implementation, the axis adjustment device 10 of this embodiment achieves a fixed connection with the test pile 30 and the anchor pile 40 through the first ring pile member 111 and the second ring pile member 112, and locks the pile center positions of the two. Then, the horizontal force loading component 20 is mounted by the retractable bearing component 12 connected in the radial direction of the two, so that the horizontal force during the horizontal force loading process can pass through the pile center of the test pile 30 and the anchor pile 40. This not only simplifies the operation process, saves time and effort, and is safe and reliable, but also improves work efficiency, ensures test quality, and ensures the accuracy of test results.

[0035] For example, refer to Figure 1 and Figure 2 In this embodiment, the first ring pile 111 and the second ring pile 112 have the same structure, both being adjustable metal cable ties 1111.

[0036] The adjustable metal cable tie 1111 ring pile assembly 11 can wrap around the test pile 30 or anchor pile 40 so that the center line of the telescopic bearing assembly 12 passes through the pile core, thus meeting the axis adjustment requirements of the horizontal static load test.

[0037] For further details, please refer to Figure 1 The adjustable metal cable tie 1111 in this embodiment may include a strip iron sheet 1111-1. One end of the strip iron sheet 1111-1 is provided with a buckle 1111-1-1, and the other end is provided with a plurality of adjustable slots 1111-1-2 that can be connected to the buckle 1111-1-1.

[0038] In practice, the buckle 1111-1-1 is connected to buckles 1111-1-1 in different positions, which makes the length of the strip iron sheet 1111-1 adjustable, that is, it can obtain rings with different inner diameters, which can meet the testing needs of piles with different diameters.

[0039] In use, the adjustable metal cable tie 1111 is untied and wrapped around the test pile 30 and anchor pile 40. The protruding buckles 1111-1-1 on the strip iron plate 1111-1 and the pre-drilled adjustable slots 1111-1-2 on the strip iron plate 1111-1 are used to tighten and secure the cable tie to the test pile 30 and anchor pile 40. At this time, the telescopic channel steel 121 is aligned with the center of the two piles, ensuring that the loading direction is always perpendicular to the pile center.

[0040] For example, refer to Figure 1 and Figure 2 The telescopic load-bearing component 12 is a telescopic channel steel 121, and the two ends of the telescopic channel steel 121 are respectively welded and fixed to the strip iron sheet 1111-1 of the first ring pile 111 and the second ring pile 112.

[0041] The design of the telescopic channel steel 121 specifically realizes the adjustable size of the telescopic load-bearing component 12, which can flexibly meet the testing requirements of piles with different pile spacings.

[0042] Further preferred options are those that refer to... Figure 1 and Figure 2 The retractable load-bearing component 12 in this embodiment may include a plurality of retractable channel steels 121 that are interlocked with each other, and the ends of the two retractable channel steels 121 located at the beginning and end are respectively welded to the first ring pile 111 and the second ring pile 112.

[0043] The multiple overlapping telescopic channel steels 121 are suitable for situations with large pile spacing, and the test pile 30 and anchor pile 40 can be connected over a long distance by overlapping.

[0044] Reference Figure 2 In this embodiment, the horizontal force loading component 20 may include a jack 21 connected between the test pile 30 and the anchor pile 40. The jack 21 is connected to the test pile 30 and the anchor pile 40 respectively through a first shim block assembly 211 and a second shim block assembly 212. The jack 21, the first shim block assembly 211 and the second shim block assembly 212 are placed together on the telescopic channel steel 121.

[0045] In practice, the first shim block assembly 211 and the second shim block assembly 212 have the same structure, both consisting of several shims and several blocks stacked together. During use, the jack 21 utilizes the telescopic channel steel 121 to ensure the accuracy of the loading force direction.

[0046] This embodiment provides an axis adjustment device 10 for horizontal static load testing in pile foundation inspection. Its complete working process is as follows:

[0047] During the horizontal static load test, the pile spacing is first measured and determined. Then, the length of the telescopic load-bearing assembly 12 is adjusted to match the distance between the piles. After determining the dimensions, the first ring pile member 111 and the second ring pile member 112 of the ring pile assembly 11 are connected to the test pile 30 and the anchor pile 40, respectively. After completing the above steps, the horizontal force loading assembly 20 is placed on the telescopic load-bearing assembly 12, and the test can then begin.

[0048] As can be seen, this process is simple, convenient, safe and reliable, eliminating the need to constantly adjust the loading direction of the pad block and jack 21, thus improving work efficiency.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
