  Next, a wall structure according to a preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view showing a state in which a wall structure according to a preferred embodiment of the present invention is installed at a boundary of a water body structure. FIG. 2 is a perspective view of the wall structure shown in FIG. It is the expansion perspective view which showed the part.

  A wall structure according to a preferred embodiment of the present invention, indicated generally by the reference numeral 10 in FIG. In FIG. 1, the extension direction of the wall structure 10 is an x direction, a cross-sectional direction orthogonal to the extension direction is a y direction, and a vertical direction is a z direction.

  The wall 12 is formed by fitting or arranging a number of wall components in the x-direction and embedding the lower part in the lower support.

  As shown in FIG. 3A, the hat-shaped steel sheet pile 14 constituting the wall member in the embodiment shown in FIGS. 1 and 2 mainly reduces the bending moment when a load such as earth pressure is applied. It has a flange 14a, an arm portion 14b, and a joint portion 14c that resist, and a web 14d that mainly resists shearing force. More specifically, in the hat-shaped steel sheet pile 14, a pair of webs 14d are respectively arranged continuously so as to expand outward from both edges of the flange 14a, and each web 14d is substantially parallel to the flange 14a. The arm portions 14b are arranged continuously so as to form a joint portion 14c, respectively.

  One end of the joint 14c of the hat-shaped steel sheet pile 14 is formed with an upper opening claw 14c1, and the other of the joint 14c is formed with a lower opening claw 14c2. The upper opening claw 14c1 and the lower opening claw 14c2 are formed in shapes complementary to each other, and a joint of the other hat-shaped steel sheet pile 14 adjacent to the upper opening claw 14c1 of the joint portion 14c of one hat-shaped steel sheet pile 14 is formed. The lower opening claw 14c2 of the hat-shaped steel sheet pile 14 is fitted into the lower opening claw 14c2 of the hat-shaped steel sheet pile 14, and the upper opening claw of the joint 14c of the other hat-shaped steel sheet pile 14 adjacent thereto. A desired number of hat-shaped steel sheet piles 14 can be fitted by fitting 14c1. FIG. 3B is an enlarged view showing a fitting portion of the joint portion of the hat-shaped steel sheet pile 14.

  The lower support in which the lower part of the wall 12 is embedded is foundation ground or concrete footing. The foundation ground includes the ground formed by the improved soil. The embedding of the wall body 12 in the foundation ground is performed by vibration or impact using a vibratory hammer, a hydraulic hammer, or the like.

  The wall structure 10 also includes an outer surface side passing member 16 arranged at a predetermined position on the outer surface of the wall 12 so as to extend in the extension direction (x direction). The outer surface side passing member 16 plays a role of suppressing the ingress and egress in the y direction due to the driving of the hat-shaped steel sheet pile 14 to be fitted. That is, when a large number of hat-shaped steel sheet piles 14 are fitted, the individual hat-shaped steel sheet piles 14 may move in and out in the y-direction as they are driven. By doing so, the hat-shaped steel sheet pile 14 can be made to extend substantially in a straight line in the extension direction (x direction), thereby preventing the soil water pressure from acting on the wall 12 in an uneven manner. Further, the outer surface side passing member 16 also plays a role of preventing run-up of the drifting material and the like, as described later.

  The arrangement height of the outer surface side passing member 16 is generally, but not limited to, the upper half of the entire height of the wall structure 10. Further, although the number of the outer surface side passing member 16 shown is one, two or more outer surface side passing members 16 may be provided.

  As the outer surface side passing member 16, a shaped steel (H-shaped steel, channel steel, etc.) and a steel pipe (circular steel pipe, square steel pipe) are used, but a member functioning as a beam member other than the shaped steel and the steel pipe may be used. Good.

  The wall structure 10 is also provided on the outer surface side of the wall body 12 with a mounting member 18 disposed at an upper end of the wall body 12 at a predetermined interval in the extension direction (x direction), and one part is mounted. An outer-side locking member 20 connected to the member 18 and the other part connected to the outer-side passing member 16, and an inner surface disposed on the inner surface side of the wall 12 and one part connected to the mounting member 18. And a side locking member 22.

  The main role of the mounting member 18 is to support the outer surface side passing member 16 in a suspended state via the outer surface side engaging member 20 and to suspend an inner surface side passing member 24 to be described later via the inner side engaging member 22. It is to support in a lowered state. Further, the mounting member 18 may be used as a part of an overhanging device 26 described later. The placing member 18 is basically placed on the upper end of the wall 12 and is prevented from dropping by providing the outer-side locking member 20 and the inner-side locking member 22. If the placement member 18 is not properly seated at the upper end of the wall 12, the placement member 18 is fixed to the wall 12 using auxiliary means such as welding so that the placement member 18 does not fall. Have been. When the placing member 18 is not fixed to the wall body 12 but is placed on the upper end of the wall body 12, there is an advantage that the removing operation is easy. In addition, since it is difficult to construct the hat-shaped steel sheet pile 14 so that the upper ends thereof are all at the same height, the height of the hat-shaped steel sheet pile 14 is adjusted using an appropriate adjuster (not shown). Is preferred.

  As the mounting member 18, a shaped steel (H-shaped steel, channel steel, etc.) or a steel pipe (circular steel pipe, square steel pipe) is used, but a member that functions as a beam member other than the shaped steel and the steel pipe may be used. .

  The outer surface side locking member 20 has an upper end attached to the lower surface of one end of the mounting member 18 and a lower end attached to the outer surface side passing member 16 (see FIG. 5A). Alternatively, the upper side surface of the outer side locking member 20 may be attached to one end of the mounting member 18 (see FIG. 5B), or the lower side surface of the outer side locking member 20 may be attached to the side surface of the outer side passing member 20. (See FIG. 5C). The attachment of the outer-side locking member 20 to the mounting member 18 and the attachment of the outer-side locking member 20 to the outer-side passing member 16 are performed by welding or mechanical fastening (bolt fastening or the like).

  The outer-side locking member 20 serves to arrange the outer-side through member 16 at a predetermined position, and cooperates with the inner-side locking member 22 to place the mounting member 18 on the upper end of the wall 12. Play the role of holding.

  Shaped steel (H-shaped steel, channel steel, etc.), steel pipe (circular steel pipe, square steel pipe), steel plate, or the like is used as the outer surface side locking member 20, but a member functioning as a beam member other than the shaped steel and the steel pipe is used. May be used.

  The upper end of the inner surface side locking member 22 is attached to the lower surface of the other end of the placing member 18 (see FIG. 6A). Alternatively, the upper end side surface of the inner surface side locking member 22 may be attached to the other side surface of the mounting member 18 (see FIG. 6B). The attachment of the inner surface side locking member 22 to the mounting member 18 is performed by welding or mechanical fastening (for example, bolting).

  As described above, the inner surface side locking member 22 cooperates with the outer surface side locking member 20 to hold the mounting member 18 on the upper end of the wall body 12, and also serves as an inner surface side described later. When the through member 24 is arranged, it serves to attach the inner surface side member 24 to a predetermined position.

  As the inner side locking member 22, a shaped steel (H-shaped steel, channel steel, etc.), a steel pipe (circular steel pipe, square steel pipe), a steel plate, or the like is used, but a member that functions as a beam member other than the shaped steel and the steel pipe May be used.

  Preferably, the wall structure 10 includes an inner surface through member 24 arranged at a predetermined height on the inner surface of the wall 12. The inner surface side passing member 24 plays a role of further suppressing the ingress and egress in the y direction due to a construction error of the hat-shaped steel sheet pile 14 fitted. That is, as described above, when a large number of hat-shaped steel sheet piles 14 are fitted, the individual hat-shaped steel sheet piles 14 may enter and exit in the y-direction. However, the hat-shaped steel sheet pile 14 is more extended in the extension direction (x direction) by providing the inner surface through member 24 and making the inner surface of each hat-shaped steel sheet pile 14 along the inner surface through member 24. It is possible to ensure that they are almost aligned on a straight line.

  The inner side passing member 24 may be attached to the lower end of the inner side engaging member 22 (see FIG. 6B), or the side surface may be attached to the lower end side surface of the inner side engaging member 22 (FIG. 6 (c)). Attachment of the inner surface side passing member 24 to the inner surface side locking member 22 is performed by welding or mechanical fastening (for example, bolting).

  As the inner surface side passing member 24, a shaped steel (H-shaped steel, channel steel, etc.) and a steel pipe (circular steel pipe, square steel pipe) are used, but a member that functions as a beam member other than the shaped steel and the steel pipe may be used. Good.

  Preferably, the wall structure 10 includes an overhanging device 26 that protrudes outward or upward from the mounting member 18 or the outer surface side locking member 20. The overhanging device 26 plays a role in preventing drifting material such as driftwood from running up.

  FIG. 7 is a diagram showing various forms of the overhanging device 26. That is, in FIG. 7A, the overhanging device 26 protrudes outward from the outer surface side locking member 20, and in FIG. 7B, the overhanging device 26 protrudes upward from the placing member 18. . In FIG. 7C, the overhanging device 26 is attached to the outer surface of a member that protrudes upward from the mounting member 18 so as to extend in the horizontal direction. In FIG. The mounting member 18 is attached to the upper surface of a member fixed to the outer surface end of the mounting member 18 so as to extend outward substantially in parallel with the outer surface passing member 16. Note that each form shown in FIG. 7 is merely an example, and an overhanging device 26 other than the form shown may be employed. The attachment of the overhanging device 26 to the placing member 18 or the outer-side locking member 20 is performed by welding or mechanical fastening (for example, bolting).

  As the overhanging device 26, a shaped steel (an H-shaped steel, a channel steel, etc.), a steel pipe (a circular steel pipe, a square steel pipe), a steel plate, or the like is used, but a member that functions as a beam member other than the shaped steel and the steel pipe is used. Is also good.

  Preferably, the wall structure 10 includes a screen wall 28 disposed above the wall 12. FIG. 8 illustrates a state in which the screen wall 28 is disposed in a gap between a pair of support members provided on the upper surface of the mounting member 18, but the screen wall 28 is disposed in another appropriate form. May be. Like the overhanging device 26, the screen wall 28 plays a role in preventing drifting material such as driftwood from running up.

  The screen wall 28 shown in FIG. 8 is formed by stretching a net-like body (made of metal or plastic) 28b on a rectangular frame 28a made of a metal material (steel, aluminum, etc.). Any other suitable form or material may be used as long as the above can be prevented.

  Preferably, the wall structure 10 includes a stay 30 disposed on the inner surface side of the wall 12 and a tie having one end connected to at least an upper portion of the wall 12 and the other end connected to the stay 30. Material 32 is provided. By installing the tie member 32, the installation position of the tie member 32 becomes a fulcrum of the wall body 12, and the displacement of the head of the wall body 12 and the bending moment generated on the wall body 12 are reduced. Although one tie member 32 is shown in FIG. 9, a plurality of tie members 32 are basically provided at predetermined intervals in the extension direction (x direction). Further, the tie members 32 may be provided in a plurality of stages in the vertical direction (z direction).

  As the stay 30, a straight pile (see FIG. 9A), a group pile (see FIG. 9B), or another wall body (see FIG. 9C) is used. As the tie member 32, a tensile member such as a tie rod or a tie wire is used.

  FIG. 9D is an enlarged view showing an example of a place where the tie member 32 is attached. The outer surface side passing member 16 shown in FIG. 9D is configured by a pair of channel steels 16a and 16b that are vertically spaced at a predetermined interval. The channel steels 16a and 16b are vertically held at predetermined intervals by an interval holding member made of a steel member or the like. As an example of the arrangement of the spacing members, the spacing members 16c are arranged between the webs of the channel steels 16a and 16b or at predetermined locations on the flange surface, thereby forming a gap between the channel steels 16a and 16b. FIG. 9D shows a state in which a spacing member is disposed between the webs of the channel steels 16a and 16b. As another example of the arrangement of the spacing members, a spacing member 16c made of a strip steel plate or the like is arranged at a predetermined position on the flange surface of the channel steel 16a, 16b, and welded or bolted to the flange surface of the channel steel 16a, 16b. There is also a method of attaching (not shown). Then, the tie member 32 is passed through the gap formed by the spacing member 16c, and is fixed by a predetermined method. The vicinity of the attachment point of the tie member 32 is a point where the shearing force and the bending moment are particularly large. If the channel steels 16a and 16b are not held at the correct positions at these points, the cross section of the channel steels 16a and 16b is not obtained. The performance may be degraded, and the tension on the tie member 32 may widen the gap on one side of the channel steel, and may cause a dangerous state. Therefore, by attaching the spacing member 16c for maintaining the vertical spacing at the location where the tie member 32 is attached, it is possible to avoid the above-mentioned dangerous situation. The inner surface side passing member 24 may be configured similarly to the outer surface side passing member 16. In the illustrated example, a pair of channel steels is used as the outer surface side passing member 16, but an appropriate member other than the channel steel (for example, an H-section steel) may be used.

  FIG. 10 is a schematic diagram showing an example in which a wall structure 10 including a row of wall bodies 12 is used as a temporary closing work. That is, the wall structure 10 is installed in a water area at a predetermined distance from the land (there is no water when the wall structure 10 is installed, and often becomes a water area due to flooding). A space is secured by preventing drainage or intrusion of water between the object 10 and water, and various operations are to be performed inside the space.

  Preferably, the wall structure 10 includes a second wall 34 provided at a location spaced from the wall 12 by a predetermined distance. The second wall 34 may have the same configuration as the wall 12 or may have a configuration different from that of the wall 12 (for example, a circular steel pipe sheet pile is used as a wall component instead of a hat-shaped steel sheet pile. ). The space between the wall 12 and the second wall 34 is filled with a filling material (such as earth and sand).

  FIG. 11 includes a second wall 34 provided at a location spaced from the wall 12 by a predetermined distance, and a filling material (such as earth and sand) is filled in a space between the wall 12 and the second wall 34. It is the schematic diagram which showed the example which uses the wall body structure 10 formed by filling as temporary closing work. That is, the wall structure 10 is installed in a water area at a predetermined distance from the land (there is no water when the wall structure 10 is installed, and often becomes a water area due to flooding). A space is secured by preventing drainage or intrusion of water between the object 10 and water, and various operations are to be performed inside the space.

  The wall structure 10 including the second wall 34 has stronger earth-water pressure resistance and watertightness. Note that a tie material (not shown) having one end connected to at least the upper portion of the wall 12 and the other end connected to at least the upper portion of the second wall 34 may be provided.

  As described above, in the wall structure 10, there are cases where there is a backing material (such as earth and sand) on the inner surface side (FIG. 9) and cases where there is no backing material (such as earth and sand) (FIGS. 10 and 11). There are both.
