PROBLEM TO BE SOLVED: To provide a connection structure of a steel pipe sheet pile, in which, among steel pipe sheet piles inserted in the underground around a foundation structure at construction of the foundation structure, an upper steel pipe sheet pile which is nearer to the ground and unrequired after completing the construction of the foundation structure, is connected to an upper steel pipe sheet pile neighboring thereto in a horizontal direction above the lower steel pipe sheet piles, in a state that the upper steel pipe sheet pile can be removed without requiring cutting after completing the construction of the foundation structure, while leaving the lower steel pipe sheet pile inserted in the lower side in the underground.SOLUTION: In a connection structure of a steel pipe sheet pile, an upper steel pipe sheet pile 2 is rotated with respect to a lower steel pipe sheet pile 1 about an axis to be connected to the lower steel pipe sheet pile 1, and is rotated in the opposite direction to be freely separated from the lower steel pipe sheet pile 1. The upper steel pipe sheet piles 2, 2 neighboring to each other in the horizontal direction above the lower steel pipe sheet piles 1 are aligned in a state where a clearance is secured between joint parts 2a, 2a thereof. Then, a joint member 3 different from both of the upper steel pipe sheet piles 2, 2 is inserted between both of the joint parts 2a, 2a of the neighboring upper steel pipe sheet piles 2, 2, and thereby connecting the neighboring upper steel pipe sheet piles 2, 2 to each other.SELECTED DRAWING: Figure 1 |
