Abstract

PURPOSE:To adsorb large waves effectively from permeable slots and dissipate the waves efficiently, by laying a large number of crushed stones on suction- proof material stretched on the bottom of the sea, and by piling up precast concrete armor units having the permeable slots, on the crushed stones with a constant gradient. CONSTITUTION:A fascine mattress 12 and a suction-proof member 13 are stretched on the sea-bottom section of the front surface of an upright breakwater 11, and on the materials 12, 13, crushed stones 14, cobble-stones 15 and concrete blocks 16 are arranged. Besides, a pad squirred cage cylinder 17 and a wire cage cylinder 18 ar stretched over the blocks, and precast concrete armor units 21 having permeable slots are piled up with approx. 30-50% gradient to complete a wave dissipation revetment wall. As a result, large waves dashing against the wave dissipation revetment wall are passed into the revetment wall from the permeable slots of the precast concrete armmor units 21, and are dissipated.

[Related technologies and their problems] In conventional general wave-dissipating seawalls, as shown in Fig. 6, the front surface or the front and back surfaces of the vertical dyke 1 and the diagonal wall dyke are protected with concrete blocks 2 stacked with many protrusions. It is constructed in such a way.

However, in these wave-dissipating seawalls, the slope of the concrete blocks piled up is about i: 1.3 to 1: 2.0, as shown in Japanese Patent Publication No. 55-47166, which is considerably lower than that of natural beaches. Because it is steep and has many protrusions throughout, the part that is submerged into the sea does not eliminate the waves due to the effects of the protrusions placed on the steep slope, but actually makes the waves larger. In addition, while large waves caused by typhoons and seasonal winds gradually disappear in the case of natural beaches, on the artificially constructed beaches mentioned above, on the contrary, the waves become large, and the waves increase due to upright embankments and r:I.
V-levees are being climbed over, causing disasters. In addition, the scouring force caused by incoming waves or reverse undertow waves is not reduced and is applied directly to the side, so there is a problem that the blade tends to sink due to the scouring force.
