の簡易化を可能とするものとされている。However, steel pipe piles used for landslide prevention often have poor working conditions, welding piles requires a lot of work preparation, and welding without quality defects requires great skill. Due to the high cost, a joint pile method using a cylindrical sleeve has been developed as a method to reduce the number of welded parts as much as possible and increase joint strength. for example,
As shown in FIG. 11, the joint portion 4 is connected to a cylindrical sleeve 6
Then cover the cylindrical sleeve 6 and the upper and lower steel pipe piles 1.2.
A method of holding the spacers at a constant gap 8 using spacers such as steel bars 7a and 7b, closing the lower end using a closing material 9, and then injecting a filler such as mortar into the gap 8 is called "Erosion Control/Landslide Prevention Emergency". Slope collapse prevention construction method” (Showa 53)
November 20, 2015, Sankaido Co., Ltd.), page 429. *A method similar to this is disclosed in Japanese Utility Model Application Publication No. 56-125426, as shown in Figure 2, in which the main pipe pile 1 and the lower steel pipe pile 2 are joined by simple welding. The joint portion 4 is covered with a cylindrical sleeve 6, and then the lower end of the cylindrical sleeve 6 and the lower steel pipe pile 2 are welded 10 to prevent leakage, and then resin is injected as a filling hardening material 11. These were developed as an efficient method for reinforcing the joint portion 4, and are said to reduce the number of welding points and simplify the work.

ある。(Means for Solving the Problems) The present invention involves joining upper and lower steel pipe piles whose pipe ends are each formed into a joint with mark A, and then covering the joined portion with a cylindrical sleeve, and then connecting the upper and lower steel pipe piles to the cylindrical pipe. In a joint pile method for steel pipe piles in which a filling hardening material is injected into the gap with the shaped sleeve, at least two or more screw holes are threaded in the inner inro joint in advance, and nuts are fitted into the peripheral wall of the outer inro joint opposite to the screw holes. A mating hole is prepared, and before fitting the Inro joint, a vault with turning holes or grooves in the details is screwed into the screw hole so that the tip does not protrude from the inside, and then the outer Inro joint is fitted. , the ball F is rotated from the nut fitting hole to protrude into the nut fitting hole, and the nut is screwed into the upper and lower steel pipe piles without melting.
A method for joining steel pipe piles, which is characterized by joining, and
A steel pipe pile in which the upper and lower steel pipe piles whose pipe ends are each formed into an inro joint are joined together, the joined part is covered with a cylindrical sleeve, and then a filling hardening material is injected into the gap between the upper and lower steel pipe piles and the cylindrical sleeve. In the joint pile method, at least two or more through holes are carved in advance in one of the inro joints, and a locking fitting equipped with a protruding pin is fixed to the through holes, and a direct connection of the other inro joint is made. Install a locking groove or drill a locking hole at the position corresponding to the locking fitting, fit the upper and lower steel pipe piles, and make the direct pin protrude into the locking groove or hole. This is a method for joining TiTV piles, which is characterized by joining steel pipe piles without welding.
（作用）
本発明の方法は、上・下鋼管杭が印籠継手で接合される
ため、上・下鋼管杭を嵌着した時点で芯金わせが完了す
るので、作業時間が非常に短縮できる。(Function) In the method of the present invention, since the upper and lower steel pipe piles are joined with an inro joint, the core metal fitting is completed at the time when the upper and lower steel pipe piles are fitted, so the working time can be greatly shortened.

確実で、熟練を要しないため工費が低廉ですむ。In the second joint pile method, after fitting the outer Inro joint to the inner Inro joint, the pin of the locking fitting of one Inro joint is made to protrude into the locking groove or locking hole of the other Inro joint.・
Since the lower steel pipe piles are joined, the work is simple and reliable, and the work cost is low because no skill is required.
さらに、円筒状スリーブを利用して充填硬化材により接
合部分の補強を竹うので、接合部分の強度は非常に高く
