Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a steel sheet pile for retaining soil used in civil engineering work, etc., and relates to a steel sheet pile having a sand removing claw for preventing clogging of grip which tends to occur during continuous driving.

[0002]

[Prior Art]

 Steel sheet piles used in civil engineering work are continuously and sequentially placed in parallel in the soil.In this case, adjacent steel sheet piles are erected in such a manner that their side edges are not separated from each other. It For this reason, one of the grips of the next-order steel sheet pile is fitted to the upper end of the empty grip of the grips on both side edges of the existing steel sheet pile, and the other steel sheet pile is driven. In this case, the empty grip of the existing steel sheet pile is clogged with earth and sand at the time of driving.Therefore, the bottom end of the grip of the driven steel sheet pile pushes the earth and sand clogged in the grip of the existing steel sheet pile or pushes it around. It is inserted while pushing it away.

[0003]

[Problems to be solved by the device]

 As described above, when pushing the sand and sand in the grip of the existing steel sheet pile and pushing the steel sheet pile while pushing a part of it, the sand and sand loses their escape area in the grip and is caught between the grip and the inner wall of the grip. It was tied up, and it became a resistance and could not be easily placed, or problems such as huge damage to the grip occurred. This phenomenon was particularly prominent in soil with a lot of sand.

[0004]

[Means for Solving the Problems]

 A steel sheet pile according to the present invention for solving the above-mentioned problems is a steel sheet pile having grips on both side edges. It is characterized in that a notch is formed at the tip of the steel sheet pile on the side of the sediment removing claw.

[0005]

[Action]

 The debris removal claw of the steel sheet pile configured as described above, when fitted into the grip of the existing steel sheet pile, is jammed in the grip with the surface inclined upward from the tip of the grip toward the outside of the grip. The existing sediment is pushed out toward the grip opening, solving the problem of clogging with sediment.

【Example】

 FIG. 1 is an explanatory view showing a usage state of the first embodiment of the present invention. This embodiment is an example of a U-shaped steel sheet pile, and shows steel sheet piles 2 which are connected to each other and placed in the ground, and steel sheet piles 5 which are to be newly placed in connection with the existing steel sheet piles 2. ing. On each side edge of each steel sheet pile 2, 5, grips 6, 7, 16, 17 having a U-shaped cross section are provided symmetrically on each side edge. As shown in FIG. 2, the lower end structure of the grip 16 of the steel sheet pile 5 is processed as a sediment removing claw 18 composed of an inclined surface 14 formed by obliquely notching the tip of the grip 16 toward the outside of the steel sheet pile 5. There is. And the notch 15 is provided on the grip 16 side of the steel sheet pile 5.

The operation of the above embodiment will be described. First, the earth and sand removing claw 18 is fitted in the grip 7 in FIG. 1 in the direction A. Along with this, the inclined surface 14 of the earth and sand removing claw 18 pushes the earth and sand in the grip 7 in the B direction, and the earth and sand is gradually inserted therein. In this case, since the inclined surface 14 faces the outside of the grip 16, that is, the opening side of the grip 7 of the existing steel sheet pile 2, the soil in the grip 7 is opened by the operation of the inclined surface 14 and the cutout portion 15. It is extruded in the direction (B direction).

4 and 5 show a second embodiment of the present invention and are plan views of a straight steel sheet pile. In the grip structure of the steel sheet pile 22, the side edge is divided into two parts and the opening 21 is formed in the center. At the time of fitting, the end edge 26a of the grip 26 of the other steel sheet pile 23 is fitted into the opening 21 of the one steel sheet pile 22. In this embodiment, the tip end of the edge 26a of the grip 26 is cut out to form the inclined surface 24, and the notch 25 is formed at the lower end of the one edge 26b. The inclined surface 24 removes earth and sand in the B direction with respect to the placing direction A. FIG. 6 shows an example in which the straight steel sheet piles 22 and 23 of FIG. 4 are applied to an H-shaped steel sheet pile 28, and each grip has the structure shown in FIG. Reference numeral 29 is a box.

FIGS. 7 and 8 show an example in which linear grips 37 and 36 are applied to the Z-shaped steel sheet piles 32 and 33. Reference numeral 35 is an inclined surface. These examples can be manufactured by processing in the same manner as the straight steel sheet pile. 9 and 10 show an example in which linear grips 47, 46 are applied to the H-shaped steel sheet piles 42, 43. Reference numeral 45 is an inclined surface. These examples can be manufactured by processing in the same manner as the straight steel sheet pile.

As a structure for exhibiting the same sediment removal function, in addition to the one in which the bottom edge of the existing steel sheet pile is processed to form the soil removal claw, the grip opening side is provided at the bottom edge of the grip edge. It is also possible to attach a sludge removal claw piece with a slope to the bottom.

[Effect of the device]

 Since the earth and sand removing claw is configured at the tip of the grip of the cast steel sheet pile, the steel sheet pile can be quickly driven while removing the sand and sand clogging the grip of the existing steel sheet pile.
