[0027] The embodiment of the present application provides an anchor-pile combined compressive static load device, which solves the problem of how to conduct static load tests without damaging the test piles, main reinforcement and design around the test piles, thereby facilitating the conduct of static load tests in different experimental environments.

[0028] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0029] like Figure 1-Figure 2 As shown, by setting an anchoring mechanism, the anchoring mechanism is set in the form of at least two lower pads, two anchoring beams and four tie rods, so as to achieve relative stability between the support box plate and the auxiliary beam, so that the support box plate supports the weight part, and solves the problem of how to conduct static load tests without damaging the foundation piles around the test piles and meeting the main reinforcement of the engineering piles that are not allowed to be anchored or welded in the design, which facilitates the static load tests in different experimental environments.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Example:

[0032] like Figure 1-Figure 2 As shown, an anchor-pile combined compression static load device is used for static load test of a test pile 10, and the static load device includes a subbeam 24, an anchoring mechanism, a support box plate 30 and a jack 20 installed on the test pile 10;

[0033] There are multiple sub-beams 24, and a loading platform is provided between adjacent sub-beams 24. A ballast is placed on the loading platform. There are at least two support foot box plates 30, and the two support foot box plates 30 support the ballast.

[0034] The moving end of the jack 20 supports a plurality of sub-beams 24;

[0035] The anchoring mechanism at least includes two lower pads 31, two anchoring cross beams 32 and four tie rods 311, the lower pads 31 are all located below the support box plate 30, and the anchoring cross beams 32 are all located above the sub-beam 24 and in contact with the sub-beam 24;

[0036] The anchoring beam 32 is sleeved on two corresponding tie rods 311 . The tie rods 311 extend to the outer side of the anchoring beam 32 and have external threads 321 on their outer surfaces. An anchoring nut 33 is installed on the tie rods 311 . The interior of the anchoring nut 33 is provided with internal threads that match the external threads 321 .

[0037] Specifically, a gasket is provided between the anchor nut 33 and the anchor beam 32 to enhance the friction between the anchor nut 33 and the anchor beam 32, thereby improving the stability of the anchoring mechanism.

[0038] By setting up an anchoring mechanism, which is set in the form of at least two lower pads 31, two anchoring beams 32 and four tie rods 311, relative stability is achieved between the support box plate 30 and the sub-beam 24, so that the support box plate 30 supports the weight part, which solves the problem of how to conduct static load tests without damaging the foundation piles around the test piles and meeting the main reinforcement of the engineering piles that are not allowed to be anchored or welded in the design, and facilitates the conduct of static load tests in different experimental environments.

[0039] The lower pads 31 are all arranged perpendicularly to the support box plates 30 , and the anchoring beams 32 are all arranged perpendicularly to the lower pads 31 .

[0040] By setting the installation position between the support box plate 30, the lower pad 31 and the anchoring beam 32, the stability between the anchoring mechanism and the auxiliary beam 24 and the support box plate 30 is further improved, which facilitates the stability of the entire static load device when the jack 20 drives the weight piece to move upward.

[0041] The support box plate 30 extends to the outside of the sub-beam 24, and support feet 301 are placed on the support box plate 30 located on the outside. Part of the support feet 301 is anchored inside the anchoring mechanism, and the anchoring mechanism is used to achieve the stability of the support feet 301. By setting the support box plate 30 and the support feet 301, the height of the test device is lowered and the stability of the device is maintained, thereby reducing safety risks and avoiding damage or destruction of the foundation piles around the test piles 10.

[0042] The side of the plurality of auxiliary beams 24 close to the jack 20 is connected to the jack 20 through the main beam 23, and the main beam 23 is used to distribute the weight of the stacked ballast pieces, thereby further improving the stability of the entire device during the test.

[0043] The end of the jack 20 close to the test pile 10 is installed with the test pile 10 through the bottom plate 21, and the end of the jack 20 close to the main beam 23 is installed with the main beam 23 through the top plate 22. The area of ​​the bottom plate 21 and the top plate 22 is utilized to improve the stability of the moving end of the jack 20 when it moves upward, so as to facilitate the static load test.

[0044] Specifically, in actual application, the device is used to carry out a single pile vertical compressive static load test. During the test, the design parameters are verified, problems are found, the design is optimized, and the above work is repeated until an anchor pile combined compressive static load device with wide applicability, high convenience, low cost and high efficiency is developed.

[0045] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0046] 1. By setting an anchoring mechanism, the anchoring mechanism is set in the form of at least two bottom pads 31, two anchoring beams 32 and four tie rods 311, which solves the problem of how to conduct static load tests without damaging the foundation piles around the test piles and satisfying the main reinforcement of the engineering piles that are not allowed to be anchored or welded in the design, and facilitates the static load test in different experimental environments.

[0047] 2. By setting the installation position between the support box plate 30, the lower pad 31 and the anchoring beam 32, the stability between the anchoring mechanism and the subbeam 24 and the support box plate 30 is further improved, which facilitates the stability of the entire static load device when the jack 20 drives the weight piece to move upward.

[0048] 3. The main beam 23 is used to distribute the weight of the stacked ballasts, further improving the stability of the entire device during the test.

[0049] 4. This method is highly practical and convenient, easy to operate, and can reduce the height and center of gravity of the static load test, which not only improves the stability of the device but also reduces safety risks.

[0050] 5. This utility model reduces costs and increases efficiency. By anchoring the support legs 301, the counterweight of the loading platform is reduced, the consumption of manpower and material resources in engineering inspection is reduced, the test cost is saved by about 20%, and the economic benefits of the company are improved.
