Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a state in which a sheet pile 1 # 1 is cast by a water jet combined method, and a state in which a U-shaped steel sheet pile 1 # 1 is cast in a groove A formed in the ground for drainage. Is shown.

The U-shaped steel sheet pile 1 # 1 is cast into a groove A formed at a constant depth so as to extend along the ground surface so as to be continuous along the width direction. The U-shaped steel sheet piles 1 # 1 to be poured are set upright in the longitudinal direction, and the upper end is lifted up and down by a crane device (not shown) and inserted one by one into the groove. A vibro device is suspended from a hook of the crane device. The upper end of the U-shaped steel sheet pile is chucked by the vibro device and inserted into the ground while vibrating with the vibro device.

Each of these U-shaped steel sheet piles 1 # 1 has a substantially U-shaped cross section orthogonal to the longitudinal direction thereof, and has joint portions 2 # 2 protruding outward at both ends in the width direction. The U-shaped sheet pile 1 # 1 is formed over the entire region in the longitudinal direction, and is driven by connecting these joint portions 2 # 2 to each other.

As shown in FIG. 2, a sheet pile guide 3 according to the present invention is attached to the upper end of a U-shaped sheet pile 1a that has been cast. The sheet pile 1b to be cast is shown on the upper left side of the drawing, and the lower end of the sheet pile 1b has been cast.
Positioning is performed by approaching the sheet pile guide 3 from the side of a, and thereafter the hanging wire of the crane device is unwound and the sheet pile 1b is lowered.

The sheet pile guide 3 has a body 4 bent in a flat plate shape and a downward projecting from the body 4, and is provided on the upper end of the U-shaped sheet pile 1a. And a guide portion 6 for guiding the joint portion 2b of the U-shaped steel sheet pile 1b to be driven into the joint portion 2a of the U-shaped steel sheet pile 1a to be driven. ing.

The body 4 has a U-shaped steel sheet pile 1 in cross section.
The flat plate material is bent into a V-shape so as to match the cross-sectional shape of one half in the width direction of a. In addition, the component surfaces 4a and 4b of the body 4 have their central portions removed in a rectangular shape to reduce the weight. Also, each constituent surface 4 of the body 4
A rectangular locking claw 5 # 5 is attached to the lower part of each of a and 4b so as to protrude downward. On the component surface 4a constituting the center in the width direction of the U-shaped steel sheet pile 1a, one locking claw 5 is provided on each of the inner and outer surfaces of the component surface 4a at the center in the width direction. On the other hand, one locking claw 5 is attached to the outer wall surface of the side surface 4b near the bent portion 4c of the body, and one locking claw 5 is provided on the inner wall surface at the center in the width direction. Are respectively attached. These locking claws 5 are attached by welding to the outer or inner wall surfaces of the respective constituent surfaces so that the width direction thereof is perpendicular to the respective constituent surfaces 4a and 4b. In addition, this sheet pile guide 3 has a locking claw 5 # attached to a lower end thereof at an upper end thereof.
Locking claws 5 # 5 are attached to the portions corresponding to the position 5 and the sheet pile guide 3 is turned upside down to be mounted on the opposite side of the U-shaped steel sheet pile 1a shown in this drawing. It is configured for use.

As shown in FIGS. 2 and 3, the guide portion 6 includes a flat plate 7 extending from the end of the side surface 4b toward the outside of the U-shaped steel sheet pile 1a, and a side surface 4b. And a member 8 which is attached to the outer wall surface and is bent in a U-shape. At the upper end and the lower end of the flat plate 7, rectangular contact plates 9, 9 are attached so as to project from the upper and lower end surfaces, respectively. The abutment plates 9, 9 are used for positioning the guide portion 6 so as to be directly above the joint portion 2a of the U-shaped steel sheet pile 1a on which the driving portion 6 is cast. Use by contacting the end face of the part.

The member 8 bent in a U-shape is formed so that its width direction is perpendicular to the component surface 4b,
To the flat plate 7. Also, this member 8
Are provided so that a gap of a predetermined size is formed between the bent portion 8a and the flat plate 7 substantially at the center of the component surface 4b in the vertical direction, and the upper and lower ends 8b and 8c are formed at the upper or lower ends of the component surface 4b. It is attached so as to protrude from the device to some extent.

The gap formed between the flat plate 7 protruding outward and the member 8 bent in a U-shape extends along the flat plate 7 along the joint portion 2b of the U-shaped steel sheet pile 1b to be driven. The gap formed between the flat plate 7 and the bent portion 8a may be slightly larger than the thickness of the joints 2a and 2b of the U-shaped steel sheet piles 1a and 1b.

If the sheet pile guide 3 is used, the swing of the U-shaped steel sheet pile 1b in which the guide groove formed between the upper end of the flat plate 7 and the upper end of the U-shaped member 8 is lifted is restrained. And
The positioning of the sheet pile 1b can be performed very easily. Also, even if the lifted U-shaped sheet pile 1b collides with the body 4 of the sheet pile guide 3 from the side, the sheet pile guide 3 is kept at the upper end of the U-shaped sheet pile 1a already driven by the locking claws 5 ‥ 5. The sheet pile guide 3 does not fall,
Swaying of the profiled sheet pile 1b is suppressed. Since the width of the guide groove is reduced to approximately the same size as the thickness of the joint 2b at the bent portion 8a, the lower end of the joint 2b is lowered by lowering the lifted U-shaped sheet pile 1b. Is naturally guided to the upper end of the joint 2a of the U-shaped sheet pile 1a that has been driven.

In order to form the main sheet pile guide 3 with high precision, it is necessary to make new parts of the main sheet pile guide 3, but it is sufficient if only rough dimensions are obtained. In the case where it is not necessary, the function and effect can be sufficiently obtained even if it is formed using waste material of a shape steel such as an angle material or a channel material.

Although the sheet pile guide has been described by taking the U-type steel sheet pile as an example, the present invention is not limited to this, and the present invention can be applied to the case of driving a straight sheet pile, a Z-shaped sheet pile, or an H-shaped sheet pile. Needless to say. When the present invention is applied to sheet piles having other shapes, a sheet pile guide which is easy to use can be obtained by forming the cross section of the body into a shape suitable for the type of sheet pile. Further, in the embodiment described above, since the drainage is formed by the water jet combined construction method, a drainage groove is formed on the ground, but when a sheet pile is directly driven on the ground without forming a groove. Needless to say, this sheet pile guide can also be used.

[0020]

As described above, according to the present invention, the sheet pile can be positioned safely and efficiently by using a sheet pile guide having a simple structure, and the construction time can be reduced.
