(イ) 技術分野
本発明は、サブマージドウオータージエツトを
利用して、磯焼けした沿岩部の岩礁表面を再生す
る方法と装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field The present invention relates to a method and apparatus for regenerating the surface of a rocky reef in a rocky area using a submerged water jet.
(ロ) 背景技術
沿岩部の岩礁が磯焼け現象によつて黄色又は白
色化して、コンブやワカメの胞子が付着しにくく
なり、これらの海藻の生育を阻害することが多
い。(b) Background Art Reefs along the rocks turn yellow or white due to the rocky shore phenomenon, making it difficult for kelp and wakame spores to adhere to them, often inhibiting the growth of these seaweeds.
このような磯焼け現象とは、スガモやホンダワ
ラなどの雑草類の繁茂や石炭藻の死骸によつて岩
礁面が黄色もしくは白色に変色することをいい、
これがコンブ、アラメ、カジメあるいはテング
サ、フノリなどの有用藻類が生育するところに発
生すると大きな被害を与え、また、その回復にも
数年かかるので非常に恐れられており、この現象
は近時我国の沿岸部にも広くみられ、有用海藻類
の生育の障害となつている。 This phenomenon of rocky shore exposure refers to the discoloration of the reef surface to yellow or white due to the overgrowth of weeds such as grass duck and sargassum, and the carcasses of coal algae.
When this occurs in areas where useful algae such as kelp, arame, kajime, amanita, and funori grow, it causes great damage and is extremely feared because it takes several years to recover. It is also widely found in coastal areas, and is a hindrance to the growth of useful seaweeds.
その対策としては、岩礁面をひつかくこと、磯
そうじ、投石等が行なわれて来たが、あまり効果
がなく、現在いろいろその再生対策技術が開発さ
れ提案されている。 Countermeasures have been carried out such as scratching the reef surface, cleaning the rocky shore, and throwing stones, but these have not been very effective, and various regeneration techniques are currently being developed and proposed.
例えば、１）ウオータージエツト、２）岩礁爆
破、３）岩礁石投入などである。 Examples include 1) water jetting, 2) reef blasting, and 3) reef stone injection.
これらの技術のうち、ウオータージエツトの場
合には水中噴射になるので、高圧水の吐出圧力を
数100Kg／cm2以上とかなり高圧にしてもその射程
距離は著しく短くなり、その除去能率が非常に悪
い。また、岩礁爆破といつた火薬を利用する方法
も水産動物類の死滅や施工の安全性の点で問題が
ある。更に岩石の投入ではその採取、運搬、投入
に大きな労力や日時を要する等の欠点がある。 Among these technologies, waterjet uses underwater injection, so even if the discharge pressure of high-pressure water is set to a fairly high pressure of several 100 kg/cm 2 or more, the firing range is extremely short and the removal efficiency is extremely low. bad for Additionally, methods that use gunpowder, such as reef blasting, have problems in terms of killing aquatic animals and construction safety. Furthermore, there are drawbacks to the inputting of rocks, such as the fact that collecting, transporting, and inputting the rocks requires a great deal of labor and time.

有効射程距離が短くなる。 In general, water jets are used for cutting soil, rocks, etc. in the atmosphere, and have good cutting efficiency, but as mentioned above, their efficiency drops dramatically underwater, and this phenomenon only occurs at deep depths. I see, its effective range becomes shorter.
従つて、このウオータージエツトにより磯焼け

A method for regenerating the surface of rock-scorched ground, which is characterized by scraping and removing the rock-scorched surface of rocky reefs, etc. by high-pressure jetting. 2. A tubular structure with a plurality of double pipe nozzles 9 provided on the lower surface, which are formed so that pressurized water is injected from the jet injection hole 22 in the center and compressed air is injected from the annular compressed air injection hole 23 on the outer periphery. The middle part of the support 1 is attached to the tip of a rod 2 formed into double inner and outer pipes 2a and 2b, and inside the support 1 there is a water passage 10 communicating with the rod inner pipe 2a and a rod outer pipe 2.
An air passage 11 is formed which communicates with the nozzle 9, and a double swivel 3 is fixed to the middle part of the rod 2 and communicates with the rod 2, and the swivel 3 is provided on the outside thereof. The rod 2 is rotatably supported by a rotary drive unit 4, and the inner tube 2a of the rod 2 is supplied with pressurized water.
A surface regeneration device for rocky rocky ground, characterized in that supply pipes 6 and 7 for supplying compressed air are connected to the surface. 3. In claim 2, the rotation of the nozzle support 1 causes the compressed air to be supplied to the rod outer tube 2b to be rotated by the rotation drive section 4 of the double swivel 3.
When rotating by directly supplying to the rod inner tube 2a
A surface regeneration device for rocky rocky ground, which is one of the systems in which pressurized water is supplied to the rotation drive unit 4 of the double swivel 3 to rotate it.
