Description

Technical Field

[0001] The present application relates to the field of steel pipe piles, and more specifically, to a steel pipe pile foundation structure. Background Art

[0002] Steel pipe piles are composed of steel pipes, tongue and groove tenons and tongue and groove pins. The tongue and groove is vertically connected to the pipe wall at the left end of the steel pipe diameter. The cross-section of the tongue and groove is a square frame with one side open. Reinforcing ribs are provided on the side of the tongue and groove. The tongue and groove pin is vertically connected to the pipe wall at the right end of the steel pipe diameter and at a radial position. The groove section of the tongue and groove pin is I-shaped. Steel pipe piles are suitable for foundations in dock and port construction. Their diameter range is generally between 400-2000mm, and the most commonly used is 1800mm.

[0003] Steel pipe piles need to be installed above the foundation when in use. Most of the existing steel pipe piles are directly fixed with bolts. Although this method is very convenient, the stability of the fixation is relatively poor, and the bolts will become loose after long-term use. Therefore, a steel pipe pile foundation structure is urgently needed to solve the above problem. Utility Model Content

The movable plate makes the limiting groove and the fixing nut fit tightly under the traction of the pulling spring. When the steel pipe body is installed, the staff places the two supporting half rings on the side walls of the steel pipe body and fixes them through a fixing assembly. A supporting assembly is provided between the supporting half ring and the base, which can support and stabilize the supporting half ring, and then support and stabilize the steel pipe body.

[0008] Furthermore, a positioning block is fixedly installed on the inner wall of the limiting groove close to the steel pipe body, and a positioning groove matching the positioning block of the same group is opened on the side wall of the fixing nut.

[0009] By adopting the above technical solution, the positioning block is engaged with the positioning groove formed on the side wall of the fixing nut, thereby further positioning and fixing the fixing nut, which helps to prevent the limiting groove from being disengaged from the fixing nut.

[0010] Furthermore, sliding blocks are fixedly installed on both sides of one end of the movable plate away from the steel pipe body, and the inner wall of the movable groove is provided with a sliding groove matching the sliding block on the same side.

[0011] By adopting the above technical solution, when the movable plate slides in the movable groove, the movable plate slides in the sliding groove with the slider, and the cooperation of the slider and the sliding groove helps to prevent the movable plate from being separated from the movable groove.

[0012] Furthermore, the fixing assembly includes fixing plates fixedly mounted on both sides of the two supporting half rings, through holes are provided on the surfaces of the fixing plates, and the two fixing plates on the same side are fixed by fastening bolts and fastening nuts.
