[0038] The traditional pier foot connection method adopts reinforced concrete column foot and foundation welding or bolt connection, but when the column foot is located in water and under silt, this connection method has problems such as great welding difficulty, long construction period, etc.

[0039] See Figures 1-4 The embodiment of the present application provides a water pier column foot connecting structure, which comprises:

[0040] A bearing platform 1, wherein a pre-buried assembly is arranged in the bearing platform 1, and the upper surface of the pre-buried assembly is flush with the upper surface of the bearing platform 1;

[0041] An outer steel pipe 6 is fixed to the upper surface of the pre-buried assembly;

[0042] An inner steel pipe stand 3 is obliquely inserted into the outer steel pipe 6, and the outer steel pipe 6 and the inner steel pipe stand 3 are fixed through a shoe beam assembly.

[0043] It can be understood that the pre-buried assembly of the present application is fixed to the bearing platform 1, and the pre-buried assembly provides the required stability for the water pier column foot connecting structure. The upper part of the pre-buried assembly is connected with the outer steel pipe 6, so that the outer steel pipe 6 is stable and firm.

[0044] In some embodiments, the outer steel pipe 6 and the inner steel pipe stand 3 are both vertically arranged, that is, the outer steel pipe 6 and the inner steel pipe stand 3 are both perpendicular to the bearing platform 1.

[0045] In some embodiments, the outer steel pipe 6 and the pre-buried assembly are fixed by double fillet welds. It can be understood that the size of the weld leg of the welding is not less than half of the minimum butt plate thickness. In the present application, the size of the weld leg of the welding is not less than half of the thickness of the minimum anchor plate 10.

The shoe beam assembly strengthens the connecting ability of the inner steel pipe stand 3 and the outer steel pipe 6, and also strengthens the local shear resistance of the inner steel pipe stand 3.

[0050] In the present application, the bearing platform 1 and the embedded component provide the required stability for the underwater pier column foot connecting structure, the upper part of the embedded component is connected with the outer steel pipe 6, so that the outer steel pipe 6 is stable and firm; the socket type connecting structure is adopted between the inner inserted steel pipe column 3 and the outer steel pipe 6, and the inner inserted steel pipe column 3 and the outer steel pipe 6 are fastened through the shoe beam component, specifically, the shoe beam component is fixed on the outer periphery of the inner inserted steel pipe column 3, and the shoe beam component only plays a fastening and limiting role on the outer steel pipe 6, that is, the shoe beam component and the outer steel pipe 6 do not exist absolute fixation, when demolishing in the later period, the silt covered on the pier column foot does not need to be removed, and at the same time, underwater cutting is not involved, so that the inner inserted steel pipe column 3 can be directly pulled out by using mechanical equipment, which is safe, convenient, simple in construction and economical and reasonable.

[0051] It can be understood that the inner inserted steel pipe column 3 can be directly pulled out by using mechanical equipment when demolishing in the later period, and the outer steel pipe 6 in water can be used repeatedly.

[0052] Please refer to Figure 1 In some embodiments, the outer steel pipe 6 is fixedly inclined on the upper surface of the embedded component, and the inclination angle of the outer steel pipe 6 and the inner inserted steel pipe column 3 is the same.
