Description

[Detailed description of the invention] In the case of connecting concrete sheet piles, the sheet piles cannot be connected unless the guide cylinder provided in the convex strip and the cylinder provided in the concave groove match in position.

In this invention, a guide tube provided on a convex strip is held in a predetermined position within the formwork when concrete is poured, and a soft synthetic resin plate is placed along a predetermined line to close the opening of the guide tube. It was made to look like it was cut.

The present invention has a convex strip 2 on one side edge of the plate-shaped body 1 over the entire length.
A concave groove 3 that fits into the protruding strip 2 is provided on the other side edge, and a plurality of hard grooves 5 are provided on the outer periphery of a hard cylindrical body portion 4 made of hard synthetic resin, metal, etc., protruding from the center. A soft synthetic resin thin plate 9 is provided with an opening 6 in the shape of a shape, regulating grooves 7, 7 are provided on both sides of the opening 6 in parallel with the opening, and a V-shaped groove 8 is provided in the center over the entire length on the inner surface. A guide tube 10 provided on the front surface of the guide tube 6 to close the opening is buried in the protrusion 2 by a length required to be watertight so that the surface of the thin plate 9 is flush with the protruding surface of the protrusion 2. A cylindrical body 11 that fits into the cylindrical body part 4 of the guide tube 10 is fixed to one side edge of the steel strip plate 12, an anchor material 13 is provided on the other side edge, and the steel band plate 12 is fixed to the cylindrical body part 4 of the guide tube 10. The steel strip plate 12 on the side where the anchor material is provided is attached to the plate-like body 1 at the center of the groove 3 so that the protruding surface of the protrusion 2 and the concave surface of the groove 3 are in contact with each other when the cylindrical body 11 is fitted. A concrete sheet pile characterized in that a plurality of small holes 14 for grout outflow are provided in the lower part of a cylindrical body 11 that is buried and fixed to a steel strip plate 12, and a knife-like blade 15 is provided at the lower end of the steel strip plate 12. It is related to.

Next, a construction example in which a seawall is constructed using the sheet piles of the present invention will be explained.

To construct a revetment wall for a river or waterway using concrete sheet piles, A1 missing boards are driven vertically into the soil. Next, the concave groove 3 of the A2 sheet pile is engaged with the convex line 2 of the A1 sheet pile, and the steel strip plate 12 provided in the center of the concave groove 3 is attached to the cylindrical body part 4 of the guide tube 10 embedded in the convex line 2.
Fit the cylindrical body 11 provided on one side edge of the housing and press down. Then, the blade 15 at the lower end of the steel strip plate 12 presses off the v-shaped groove 8 of the thin plate 9 provided in the opening 6, and the cut surface contacts the steel strip plate 12 and forms the v-shaped groove according to driving A2. Along 8 the sheet metal 9 is cut deeper and deeper. In this way, the A1 sheet pile and the A2 sheet pile are connected. Similarly to the above, sheet piles A3, A4, etc. are driven in order to construct a seawall.

When driving the sheet piles, a gap is created between the protruding surface of the ridge 2 and the concave surface of the groove 3, and the sheet piles are pulled together and crimped together to prevent fine sand or the like from entering between the two.

After the connection, cement grout is poured into the cylindrical body 11 provided in the groove. The grout fills the cylindrical body 11, and the cylindrical body 11,
It flows between the cylindrical parts 4, fills the spaces between them, and hardens.

In addition, if the sheet pile wall is a wall surface exposed to water or air, the joints are filled with filler from the outside and combined with the grout between the cylinders, it is made watertight. However, even when no grout is injected, the cut surface of the pressed soft synthetic resin thin plate 9 comes into close contact with the surface of the steel strip plate and exerts a sand-preventing effect.

Further, according to the present invention, regulating grooves 7 are provided in parallel on both sides of the protruding opening 6 of the cylindrical body 4 installed in the protrusion 2.
7, the guide tube 10 can be reliably installed at a predetermined position within the formwork by fitting the regulating grooves 7, 7 into the protrusions of the formwork of the protrusion. Therefore, v-shaped groove 8
Not only is the thin plate 9 cut along the protrusions 2
When engaging the concave groove 3 with the groove 3, the cylindrical body part 4 of the guide tube provided on the protrusion 2 and the cylindrical body 11 provided in the concave groove fit smoothly,
It has advantages such as being able to easily connect sheet piles.
