た。BACKGROUND OF THE INVENTION Conventional techniques and their problems Conventionally, various civil engineering piles such as wooden piles, iron piles, and concrete piles have been used in civil engineering works. However, wooden piles and iron piles have the disadvantage that they rot or rust in a short period of time when used for civil engineering work in wetlands with a lot of moisture, and concrete piles have the disadvantage that they are difficult to stay firmly in place and are easy to fall out. It was hot. Therefore, in civil engineering work where the durability and fixing strength of civil engineering piles are particularly required, for example, as shown in FIG. In the case of constructing net shelves for earth retaining in multiple tiers along contour lines, the above-mentioned wooden piles, iron piles, concrete piles, etc. are all unsatisfactory.

The pile is such that the cylindrical body has a plurality of synthetic resin rings arranged at intervals in the longitudinal direction, and is welded to the outer periphery of each ring, and the convex portions and concave portions are alternately formed. The gist is that it is composed of a large number of synthetic resin threads that run in the longitudinal direction while undulating in the radial direction.

The outwardly protruding protrusions formed on the synthetic resin cylindrical body dig into the surrounding soil, allowing it to be firmly fixed.
It won't come off easily. In addition, since the cylindrical body on the surface is made up of synthetic resin rings and synthetic resin threads, even if the surface receives a strong impact, cracks will not occur across the entire surface like a normal cylindrical body. do not have.

ことなく筒状体１内部に閉じ込められている。 This cylindrical body 1 includes a plurality of very thick synthetic resin rings 11 arranged at intervals in the longitudinal direction,
It consists of a large number of synthetic resin threads 12 welded to the outer periphery of each ring 11, and these synthetic resin threads 12
all run in the longitudinal direction while undulating in the radial direction, and protrusions 13 and recesses 14 protruding outward are alternately formed. A synthetic resin cap 3 with a pointed tip is fitted onto one end (lower end in the figure) of this cylindrical body 1 to facilitate driving. Concrete 2 is integrally filled. Reinforcing bars or the like may be inserted into the concrete 2 to increase its strength. In addition, a synthetic resin cap 4 having a U-shaped cross section is attached to the other end (the upper end in the figure) of the cylindrical body 1 using an adhesive or the like to prevent the concrete 2 from being damaged during pouring. has been done. Incidentally, as shown in FIG. 2, since the gap between the synthetic resin threads 12 of the cylindrical body 1 is small, the concrete 2 is confined inside the cylindrical body 1 without protruding from the gap.

ることがない。 Civil engineering piles with such a configuration are used for net trellis construction as shown in Figure 4 and other various civil engineering works, and are driven into the ground with one end where the cap 3 is fitted facing down. . This pile driving work can be carried out easily because the tip of the cap 3 is sharp, and since the top end of the pile is protected by the cap 4, there is no fear that the concrete 2 will chip or crack. Moreover, the cylindrical body on the surface is a synthetic resin ring 1.
1 and synthetic resin threads 12, even if the surface is subjected to a strong impact, the entire surface will not crack, unlike ordinary cylindrical objects.

永久的に使用することができる。 When driven in this manner, the convex portion 13 of the cylindrical body 1 bites into the surrounding soil and is firmly fixed, providing great fixing strength and preventing it from falling out easily like conventional concrete piles. especially,
It is desirable to set the difference between the convex portion 13 and the concave portion 14 to 3 to 15 mm, since a large fixing strength can be obtained despite the low driving resistance. In addition, the synthetic resin cylindrical body and the concrete inside do not rot or rust and are resistant to deterioration, so they are highly durable and can be used semi-permanently even in civil engineering work in areas with high moisture content, such as wetlands. can.
