構築していたのである。(Prior Art and Its Problems) A conventional steel pipe pile column array has a special structure in which connecting members having a C-shaped cross section or a T-shaped cross section are fixed and projected along the axial direction at two locations in the diametrical direction of the outer peripheral surface. A steel pipe pile with a connecting member, that is, a steel pipe pile sheet pile was used, and this steel pipe pile sheet pile was constructed by press-fitting in a column shape so that adjacent connecting members fit together.

る欠点もあった。In the conventional construction method using the steel pipe pile sheet pile as described above, it is necessary to have a grounding auger for excavating the ground inside the steel pipe pile sheet pile to be press-fitted, and moreover, the upper end of the steel pipe pile sheet pile is gripped and press-fitted, A large pile driver with a long leader is required, so not only is it expensive, but the space above the column construction site is limited by highway piers, etc., such as river bank repair work. Then, there was a drawback that it could not be implemented.

トアップは免れない。As one method for solving such a problem, for example, as disclosed in Japanese Patent Laid-Open No. 47-36647, the gap between the steel pipe piles that are erected upright is made up of both steel pipe piles that are adjacent from both left and right sides thereof. A method has also been proposed in which a pair of closing plates with both sides applied to the outer peripheral surface are fastened to each other by a connecting screw rod so as to be close to each other, and the closing is performed. It is necessary to excavate and leave it open for the fastening operation of the operating rod, which inevitably leads to a significant cost increase.

価に実施することが出来る。(Operation and Effect of the Invention) The method of the present invention can be carried out as described above, and according to the method of the present invention, after the steel pipe piles are rotationally press-fitted at regular intervals, the junctions are press-fitted between the steel pipe piles. By doing so, it is possible to build a column of steel pipe piles, but especially in the method of the present invention, since the junction for closing the gap between the adjacent steel pipe piles is also press-fit along the steel pipe piles. Since it is not necessary to excavate to the junction mounting depth to open the periphery of the steel pipe pile as in the conventional case, it can be implemented at low cost.

The strength is greater than that in which both side plates are connected by the connecting screw rod, so that it is possible to prevent the transverse cross-section strength from being significantly reduced between the steel pipe piles.

価に構造することが出来る。Further, while using a junction in which a pair of both side plates are connected and integrated at a constant interval by a connecting member, an elastic body that abuts the outer peripheral surface of the steel pipe pile is attached to the side edges of the both side plates, Even if there is some variation in the spacing between the steel pipe piles and some variation in the dimensional accuracy of the junction itself, the variation is absorbed by the elastic body, and a large gap is created between the junction and the outer peripheral surface of the steel pipe pile. It is possible to easily and inexpensively construct a steel pipe pile column array having a high water-stopping effect.
