[0038] With reference to Figures 1-4 The embodiment of the present application provides a prefabricated pile connecting joint based on non-magnetic concrete, comprising a first pile body 1, a second pile body 2 and a fixing layer 3;

[0039] A plurality of connecting columns 4 are pre-buried on the first pile body 1, and each connecting column 4 has a first connecting part 5 at one end;

[0040] The second pile body 2 is provided with a plurality of connecting grooves 6 corresponding to each connecting column 4, and each connecting groove 6 is provided with a second connecting part, which is configured to be able to limit the first connecting part 5 penetrating and exceeding the inside thereof;

[0041] The fixing layer 3 is formed in the area where the first connecting part 5 and the second connecting part in each connecting groove 6 are located, so as to fix the first connecting part 5 and the second connecting part.

[0042] In a specific embodiment, the first pile body 1 and the second pile body 2 are both composed of non-magnetic concrete. Non-magnetic concrete does not contain magnetic substances, so it will not be affected by external magnetic fields and has good stability. Moreover, it can avoid the influence of external magnetic fields on external measuring equipment, thus also ensuring the accurate positioning and measurement of the prefabricated pile.

[0043] In one embodiment, a reinforcement cage (not shown in the drawings) is embedded in the first pile body 1 and the second pile body 2 to enhance the stability thereof.

[0044] In one specific embodiment, the reinforcement cage is composed of a plurality of FRP longitudinal reinforcements and a plurality of FRP transverse reinforcements arranged vertically (not shown in the drawings).

[0047] In one specific embodiment, the second connecting portion is in the shape of a tubular structure made of aluminum. It should be appreciated that the second connecting portion can also be made of other materials, and the utility model is not limited thereto, and any material of the second connecting portion that can achieve the same technical effect as the utility model is within the protection scope of the utility model.

[0048] In one specific embodiment, the second connecting portion is divided into a connecting pipe 8 and a limiting portion 9 from top to bottom, and the diameter of the lower end of the limiting portion 9 is smaller than the diameter of the upper end of the first connecting portion 5. After the first connecting portion penetrates and exceeds the limiting portion, the limiting portion can effectively prevent the first connecting portion from moving upward to limit the first connecting portion.

[0049] In one specific embodiment, the fixing layer 3 is formed by pouring cement mortar into each connecting groove and solidifying.

[0050] When the prefabricated pile is assembled, first, one side of the second pile body having the opening of each connecting groove is placed at the upper end, then cement mortar is poured into each connecting groove, and one end of the first pile body having the first connecting portion is placed above the second pile body, and each connecting column corresponds to each connecting groove, then the first pile body is moved downward, the first connecting portion penetrates and exceeds the limiting portion, and each groove is in full contact with the cement mortar, and after the cement mortar is solidified, the assembly of the first pile body and the second pile body is completed.

[0051] The utility model discloses a prefabricated pile connecting joint based on non -magnetic concrete, through embedding a plurality of connecting columns on the first pile body, and each connecting column has a first connecting part at one end, a second pile body is internally provided with a plurality of connecting slots corresponding to each connecting column, and each connecting slot is provided with a second connecting part, and the second connecting part is configured to limit the first connecting part penetrating through and beyond its interior, a fixing layer is formed in the region of the first connecting part and the second connecting part in each connecting slot to fix the first connecting part and the second connecting part.

[0052] Further, the first pile body and the second pile body are both composed of non -magnetic concrete, so that the first pile body and the second pile body can avoid the interference of external magnetic field.

[0053] Therefore, compared with the existing prefabricated pile connecting joint, the prefabricated pile connecting joint of the utility model adopts the first connecting part which can penetrate through and beyond the interior of the second connecting part, realizes the assembly of the first pile body and the second pile body, and the assembly structure is simple, so that the workload of assembly is reduced, thereby effectively improving the construction efficiency and reducing the influence on the construction process. And the accurate positioning and measurement of the prefabricated pile can be guaranteed, so that the stability and safety of the prefabricated pile in use can be guaranteed.

[0054] Although one or more embodiments of the utility model have been described above, those skilled in the art should know that the utility model can be implemented in any other form without deviating from its main idea and scope. Therefore, the above-described embodiments are illustrative rather than limiting, and many modifications and substitutions are obvious to those skilled in the art without departing from the spirit and scope of the utility model as defined in the appended claims.
