せ、従来の工法ではコスト競争力を低下させている。However, in a state where the ends of the upper steel pipe pile and the lower steel pipe pile are simply butted against each other, it is impossible to avoid a gap between the upper steel pipe pile and the lower steel pipe pile at the joint portion. Even if a filler having fluidity is injected into and filled in the gap between the reinforced inner sheath pipe and the upper steel pipe pile and the lower steel pipe pile, the filler flows out from the skimmer to the outside. Therefore, the step of inserting the reinforcing inner sheath tube into the lower end lumen of the upper steel pipe pile at about half length and injecting the filler into the gap, and further making about half the length of the reinforcing inner sheath pipe protruding from the lower end of the upper steel pipe pile. There was no choice but to take the step of inserting the filler into the inner space of the lower steel pipe pile and injecting the filler into the gap between the lower steel pipe pile and the reinforced inner sheath pipe at different times.
Therefore, the cost required for filling the gap between the reinforced inner sheath pipe and the upper steel pipe pile and the lower steel pipe pile with the filler has been increased. Further, in order to fill the filling material, special consideration such as pipe piping is required, and the time required for the joint work is lengthened, and the cost competitiveness of the conventional construction method is reduced.

幅に削減することが可能となる。According to the present invention, approximately half the length of the reinforcing inner sheath pipe 5 is inserted inside the upper end 2 of the lower steel pipe pile 1 and the lower end 4 of the upper steel pipe pile 3, respectively, and the lower steel pipe is Filling material 9 in the gap 6 between the pile 1 and the upper steel pipe pile 3 and the reinforcing inner sheath pipe 5
In the method for jointing steel pipe piles, the outer surface of the reinforced inner sheath pipe 5, the upper end 2 of the lower steel pipe pile 1 and the lower end 4 of the upper steel pipe pile 3 are preliminarily putty-like and solidified. Until the filler 9 having a variable shape is attached, and the reinforcing inner sheath pipe 5 is inserted into the inner cavities of the upper end 2 of the lower steel pipe pile 1 and the lower end 4 of the upper steel pipe pile 3, A filling state is automatically formed in the gap 6 between the lower steel pipe pile 1 and the upper steel pipe pile 3 and the reinforcing inner sheath pipe 5. Moreover, since the filler 9 is putty-like, it is possible to prevent the filler 9 from almost flowing out from the gap between the upper steel pipe pile 3 and the lower steel pipe pile 1. In addition, the bag 1 is made of a putty-like filler 9 whose shape is variable until it solidifies without flowing.
4, the upper steel pipe pile 3 and the lower steel pipe pile 3 are attached to the outer surface 10 of the reinforcing inner sheath pipe 5, the upper end 2 of the lower steel pipe pile 1 and the lower end 4 of the upper steel pipe pile 3 in advance. It is possible to completely prevent the filler 9 from flowing out from the clearance with the steel pipe pile 1. This makes it possible to fill the gap 6 between the reinforced inner sheath pipe 5, the upper steel pipe pile 3 and the lower steel pipe pile 1 with the filling material 9 as a series of operations at the same time. Moreover, no special consideration is required in terms of structure such as pipe piping, and the cost of joint work can be significantly reduced as compared with the conventional technique.
