その解決は技術的にも、経済的にも極めて困難で
ある。 Furthermore, the contact welding shown in FIG. 6 has a problem in that it cannot provide highly reliable results in terms of quality in on-site work such as landslide prevention pile construction. That is, to construct landslide prevention piles, as shown in Fig. 9, a boring scaffold 10 is constructed on a steep slope 9, a vertical hole 11 is bored using a boring machine (not shown), and then a crane (not shown) is used to construct a landslide prevention pile. ) and using the boring scaffold 10, the steel pipe piles 12a, 12b,
Vertical hole 11 is connected by welding machine 13 to 12c.
However, due to the adverse conditions of the working environment, welding defects occur even after careful welding.
Quality standards are often not met, and especially when high-tensile steel pipes are used for steel pipe piles, quality problems occur in the welds and surrounding heat-affected areas.
Solving this problem is extremely difficult both technically and economically.
さらに、第７図の継板４ａ〜４ｃを用いる方法
も、第６図の場合と同様な問題点がある。 Furthermore, the method using the joint plates 4a to 4c shown in FIG. 7 also has the same problems as the case shown in FIG. 6.

現象が生じ易いと云う問題が残されている。 Next, although the method shown in Fig. 8 has been improved in that the quality problem of the contact welded joint 6 is compensated for by using the cylindrical sleeve fitting 5, a new quality problem is added to the welded part with the round bars 7a and 7b. In addition to the problems shown in Figure 6,
A common problem with the method shown in Figure 7 is that it is surprisingly difficult to connect the leading and trailing steel pipe piles so that they align with each other on the same axis, and a phenomenon called so-called misalignment is likely to occur. has been done.

A steel pipe pile joint in which a cylindrical sleeve metal fitting having an inner diameter larger than the outer diameter is loosely fitted into the steel pipe pile joint part, and then an adhesive solidifying material is filled between the outer surface of the steel pipe pile and the inner surface of the cylindrical sleeve metal fitting. A pile method, in which the joint pile pipe end is formed in advance into a seal joint with the same outer diameter having a groove on the outer abutment surface, and after the joint is fitted, the outer abutment surface is welded around the entire circumference or partially welded. This is a method for joining steel pipe piles, which is characterized by welding.

Therefore, they can be perfectly aligned on the same axis, and there is no fear of misalignment. In addition, the outer abutment surfaces are welded to accommodate the tensile load required to temporarily join the leading and trailing steel pipe piles, and then the leading and trailing steel pipe piles are joined by bonding the cylindrical sleeve fitting and the steel pipe pile, which will be described later. This completes the process, resulting in high bonding strength and superior quality results.

さだけ突出するのみなので立穴に建て込むに当り
障害が無く施工能率が良い。 Further, since the outside of the steel pipe pile only protrudes by the height of the cylindrical sleeve metal fitting, there is no problem when building it into a vertical hole, and construction efficiency is high.
さらに、溶接作業が少なく接着方法を主体とす
