DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shaved concrete block provided on a steel sheet pile wall such as a river or sea.

[0002]

Conventionally, steel sheet piles such as U-shaped steel sheet piles are generally driven as a quay wall such as a river or sea, or a retaining wall on the ground, with their claw portions engaged with each other. Walls are used. In addition, a cap concrete block is provided on the upper part of the steel sheet pile wall to prevent corrosion or to beautify as a structure. After the concrete form is set on the outer periphery, concrete is poured into the concrete form, and after hardening, the form is removed.

[0003] However, the above-mentioned shade concrete block,
Construction work such as rebar or formwork and concrete casting must be carried out on site, so the construction period will be prolonged, and temporary brackets will need to be provided on the river side, etc. to support the formwork. There is a problem that the cost and time for the temporary construction work are required because a scaffold as a work bench on the side or the like is required. Furthermore, in winter construction, the workability is poor, and there are difficulties in the quality and curing of concrete.

[0004] In order to solve the problem of using such a formwork, Japanese Patent Publication No. 6-25410 discloses a precast concrete block on one side and a precast concrete block on the other side via a steel sheet pile wall. And a fixing means for assembling and fixing one side of the cap concrete block, the other side of the cap concrete block and the steel sheet pile wall, and the steel sheet pile wall at the lower end of each concrete block. A bottom concrete plate for a steel sheet pile wall is formed by integrally projecting a bottom plate that almost follows the recess of this type, and filling the bottom plate and the inner peripheral surface of the concrete block and the cavity surrounded by the steel sheet pile with a filler. It has been known.

In this concrete block for a sheet pile wall, one side of the concrete block and the other side of the concrete block are arranged on both sides of the steel sheet pile wall and fixed to the steel sheet pile wall by fixing means. And a cavity surrounded by a bottom plate and a steel sheet pile wall on the other side of the shank concrete, and when the filler is idled in this cavity, the lower opening of the cavity is closed by the bottom plate. Separation and downward leakage of the filler are prevented. Then, one side and the other side of the shank concrete block and the steel sheet pile wall are integrated by the filler in the cavity, so that the work of assembling the formwork and reinforcing bars can be omitted at the site, and the temporary scaffold can be installed at the site. Since there is no need for assembling, the on-site work can be reduced, and the problem of construction using conventional cast-in-place concrete can be solved.

By the way, in the above-mentioned concrete block for wall of steel sheet pile, the inner end of the bottom plate is formed in a shape substantially along the recess of the steel sheet pile, and the bottom plate is integrally formed on one side and the other side of the concrete block. Due to the provision, the shape of the shade concrete block may be relatively complicated. Also, in the construction, to make the inner edge of the bottom plate part along the steel sheet pile wall,
One side and the other side of each cap concrete block must be moved and aligned, and the one side and the other side of the cap concrete block are relatively heavy, making the positioning work complicated. There is a face. Further, even when cutting the cap concrete block for dimensional adjustment at the site or when manufacturing a cap concrete block according to the size of the site at the factory, since the bottom plate portion is provided integrally, the cutting work is performed. In addition, it is expected that the factory manufacturing work will be complicated.
