A sheet pile joint member (corresponding to a sheet pile joint) 3 with another steel pipe sheet pile to be juxtaposed is attached to each other by welding.
And although not shown in a figure, the steel pipe sheet pile P is sequentially built in an installation object part so that the sheet pile coupling members 3 may fit, and partition walls, such as a retaining wall and a revetment, are carried out by the horizontal steel pipe sheet pile group. Can be configured.
Moreover, regarding the depth direction, a predetermined length dimension can be secured by fitting and connecting the mechanical joint members 2 to each other and adding a plurality of steel pipe sheet piles P.
Although not shown in the figure, when the sheet pile joint members 3 are fitted to each other and built up to a predetermined depth, a filler such as cement milk is placed in the fitting space between the fitted sheet pile joint members 3. In many cases, it is possible to maintain a good connected state between the two steel pipe sheet piles P.
  As shown in FIG. 2, the mechanical joint member 2 includes a ring-shaped concave mechanical joint member 2 </ b> A provided at one end (for example, the lower end) of the steel pipe 1 and the other end (for example, the upper end) of the steel pipe 1. There is a ring-shaped convex mechanical joint member 2B that is provided and has a structure that can be fitted and connected to the concave mechanical joint member 2A.

The upper and lower sheet pile joint members 3 can be connected to each other by simply connecting the upper and lower steel pipe sheet piles P with the mechanical joint member 2. FIG. Are also connected in a state in which the sealing material S is interposed (see FIG. 4).
3 (c) and 4 (b) show a situation in which the upper and lower steel pipe sheet piles P are connected to each other.
Since the seal material S is compressed by the upper and lower sheet pile joint members 3, the elastically deformed seal material S can seal between the both sheet pile joint members 3 in a watertight state.
According to the steel pipe sheet pile connection structure of the present embodiment, the steel pipe sheet piles P are securely connected by the mechanical joint member 2 and the sheet material 6 is also connected to the sheet pile joint member 3 by the sealing material S interposed therebetween. It is connected in a state where water tightness at the connecting end is ensured.
Moreover, since the sealing material S can be fitted in the concave groove 7 of the sheet pile joint member 3, the steel pipe sheet piles P can be connected to each other without the sealing material S falling off.
Therefore, the connection work between the steel pipe sheet piles P can be performed easily and quickly.
Moreover, since no welding is used, smoke or the like is not generated, and adverse effects on the surrounding environment can be prevented.
[Another embodiment]
Other embodiments will be described below.

For example, the sheet pile joint 3 is illustrated in FIGS. 11B and 11C. As shown in the figure, the cross-sectional shape is a “T” -shaped steel material, and as shown in FIG. 11C, the cross-sectional shape is a combination of a steel material using two “L” -shaped steel materials. Also good.
Moreover, the attachment position of the sheet pile joint 3 with respect to the steel pipe 1 and the change of the number of attachment locations are also possible, for example, what is provided only in one place in the circumferential direction of the steel pipe 1 or provided in a plurality of three or more places. It may be a thing. Furthermore, each arrangement | positioning relationship in the circumferential direction of the some sheet pile coupling 3 can also be changed suitably.
<2> The sealing material S is not limited to the shape and material described in the previous embodiment. For example, as shown in FIG. 5, the sealing material S is made of a material such as a synthetic resin having water expandability. Also good. In this embodiment, the expansion ratio is about 2 times, and when the sealing material S is fitted into the concave groove 7, no protrusion from the concave groove 7 is seen (FIG. 5 ( a)), when in contact with water, it expands and can be surely filled and sealed between the sheet pile joints 3 (see FIG. 5B). Therefore, it is possible to prevent in advance that other objects abut on the mounted sealing material S to be damaged or dropped.
Moreover, not all the sealing material S is comprised with the material provided with water expansibility, You may comprise with the material provided with water expansibility only in part.
<3> The fitting type between the sealing material S and the sheet pile joint 3 is not limited to that described in the previous embodiment.
For example, the concave groove 7 is not limited to being formed only on the upper end surface 3a of the sheet pile joint 3 positioned below at the connection end, and for example, the lower end surface 3b of the sheet pile joint 3 positioned above at the connection end. The groove 7 may be formed in each of the upper and lower sheet pile joints 3 facing each other at the connecting end as shown in FIGS. 6 and 7. In this case, since the sealing material S is hardly exposed to the outside, the durability can be further improved.
Further, the groove 7 is not limited to the shape described in the previous embodiment. For example, as shown in FIG. 8, a notch that opens to the end face and the side face is formed at the end of the sheet pile joint 3. In addition, a similar groove 7 may be formed by fixing a member 8 serving as a wall to the side surface and partitioning the notch with the member 8 serving as a wall. In this case, since the work of forming the notch can be performed using a wide space on the outer peripheral side, the concave groove 7 can be efficiently formed.
Moreover, it replaces with the fitting form which forms the ditch | groove 7 which fits the sealing material S to the sheet pile joint 3, and as shown to FIG. 9, FIG. 10, the ditch | groove 9 is formed in the sealing material S, and a sheet pile is formed. The sealing material S may be fitted to the end of the joint 3 in an external fitting state.
  In addition, as mentioned above, although the code | symbol was written in order to make contrast with drawing convenient, this invention is not limited to the structure of an accompanying drawing by this entry. In addition, it goes without saying that the present invention can be carried out in various modes without departing from the gist of the present invention.
