Abstract

PURPOSE:To permit the mooring of a small ship by directing the tidal current downwards by providing wave-dissipating openings to the upper deck and side outer plate of the topside tank and the side outer plate of the double-bottom tank in a breakwater using a scrapped ship. CONSTITUTION:Filling soil 8 is packed into the center tank of a bulkcarrier hull 1, and the scrapped ship is used as a breakwater. In the top-side tank 4, a wave- dissipating opening 4a is provided in the upper deck 2, and an wave-dissipitating opening 5 is provided in the side outer plate 3. In the double-bottom tank 7, a wave-dissipating opening 6 is provided in the side outer plate 3. A wave-dissipating effect can thus be provided to the breakwater. Since the tidal current passes through the lower part, the small ship can be moored to the inland sea side of the breakwater.

Description

【発明の詳細な説明】 を有する廃船を用いた消波堤に関する。[Detailed description of the invention] This invention relates to a wave-dissipating dyke using a decommissioned ship.

この種，廃船を用いた消波堤は，従来第１図に示すよう

２，縦通隔壁０８，及び上甲板０４に開口０５を設けて
消波口としていた。Conventionally, as shown in Figure 1, this kind of wave-dissipating dyke using a scrapped ship is constructed by putting filling soil into the bottom of the tanker and removing the side outer plate.
2. Openings 05 were provided in the longitudinal bulkhead 08 and the upper deck 04 to serve as wave dissipation ports.

しかし、これら従来の消波堤では，外海側の大波は消波

せるが潮流として内海側に流れる為，小型船０６の係留
には適さない。However, with these conventional breakwaters, large waves on the open sea side lose energy every time they pass through the breakwater mouth, making the waves on the inland sea calm, but they flow toward the inland sea as tidal currents, so they are not suitable for mooring small boat 06. Not suitable.

タンク内を通過する潮流により，中詰±０１の流出が考

以外に中詰土投入口を設ける必要がある。消波口が比較

効，６い等の欠点があった。It is possible that the inside filling ±01 may have leaked due to the current passing through the tank. In order to input the filling material ±01, it is necessary to provide a filling hole in addition to the wave-dissipating port on the upper deck 04. Since the wave-dissipating mouth is located relatively above, there are drawbacks such as the difficulty in cleaning the inside of the port by simply replacing the sea surface within the port.

本発明は上記従来の欠点のない消波堤を提供することを
目的とするものである。The object of the present invention is to provide a wave-dissipating bank that does not have the above-mentioned conventional drawbacks.

以下，本発明を第２図および第８図の１実施例に基づき
説明する。The present invention will be explained below based on an embodiment shown in FIGS. 2 and 8.

In Fig. 2, ■ is the bulk carrier hull (other types are possible as long as it has a double bottom), ■ is the upper deck, and ■ is the outer side. 4a is the wave-dissipating opening on the upper deck of the topside tank 4, ■ is the wave-dissipating opening on the side shell of the topside tank, ■ is the wave-dissipating opening on the side shell of the double bottom, and ■ is the wave-dissipating opening on the side shell of the topside tank. The heavy-bottomed tank section, ■ indicates the filling of earth and sand in the hull center tank, ■ indicates the mound material, [phase] indicates the seabed surface, ■ indicates the inland sea, ■ indicates the open sea, and σΦ indicates the moored small boat. What is shown in Fig. 2 is the filling of earth and sand in the center of the ship.The weight of the ship and the weight of the ship. The opening part and each space part have a wave-dissipating function, and the inland sea (
This is to maintain the calm inside the embankment.

第８図は本発明の第２の実施例を示し、第２図において

In Fig. 2, ■ is a bulk carrier hull (other types are also possible as long as it has a double bottom), ■ is an upper deck, and ■ is a side outside. Board, 4a is the wave-dissipating opening on the upper deck of the top side tank 4, ■ is the wave-dissipating opening on the side shell of the double bottom, ■ is the double-bottom tank,
■ indicates filling earth and sand 9 in the top side tank, ■ indicates filling earth and sand in the center tank, ■ indicates mound material, @l indicates the seabed, Lili indicates reclaimed ± (back etc.), and @ indicates the sea.

It is a seawall that has a wave-dissipating function through the openings provided in each part of , (■) and the independent spaces (double bottom space, side space) inside the hull.

なお、バルクキャリアーの廃船を用いれば。In addition, if you use a scrapped bulk carrier.

上甲板には、大開口のハツチがあり中詰土の投入口を設
ける必要がなく、又投入しやすいので。There is a hatch with a large opening on the upper deck, so there is no need to set up an opening for filling in the soil, and it is easy to do so.

コストダウンになる。It will reduce costs.

以上、述べたように本発明による消波堤は。As described above, the wave-dissipating bank according to the present invention is as follows.

廃船の二重底タンク部の側外板と、トップサイドタンク
部の上甲板と側外板とにそれぞれ消波用の開口を設けた
ものである。Openings for wave dissipation are provided in the side panels of the double-bottom tank section of a decommissioned ship, and in the upper deck and side panels of the top side tank section.

よって本発明は、消波効果は従来と同じであるが、潮流
が下方の為、内海側に小型船の係留に適している。また
、中詰土が海水（潮流）と隔離されている為、その流出
がなく港内の汚濁防止になる。Therefore, the present invention has the same wave-dissipating effect as the conventional one, but because the tidal current is downward, it is suitable for mooring a small boat on the inland sea side. In addition, because the filling soil is isolated from seawater (tidal currents), there is no outflow of the seawater, which prevents pollution within the port.

さらに、消波口が比較的下方の為港内の比重大なる沈澱
物の入替が行なわれ、洗浄効果が大きい等の効果がある
。Furthermore, since the wave-dissipating mouth is located relatively lower, significant sediment in the port can be replaced, resulting in a large cleaning effect.
