Description
本考案は火山の噴火などによる軽石の発生により港湾施設等に軽石の流入を防ぐネットに関するものである。 The present invention relates to a net that prevents the inflow of pumice into harbor facilities and the like due to the generation of pumice due to the eruption of a volcano.
噴火などにより海中に溜まった軽石が海流により流され、港湾施設等が様々な影響を受けている。 Pumice stones accumulated in the sea due to eruptions are washed away by ocean currents, and port facilities are affected in various ways.
港湾施設には、養殖用の生簀などがあり、養殖中の魚が流されてきた軽石を飲み込み死んでしまう事例が報告されている。 It has been reported that there are fish cages for aquaculture in the harbor facilities, and the fish being cultivated swallow the pumice stones that have been washed away and die.
また港内に軽石が流入して、船舶の航行や船のエンジンなどに被害が出ている。 In addition, pumice stones have flowed into the harbor, causing damage to the navigation of ships and the engines of ships.
港内に溜まった軽石を除去することも必要であるが、ネットで流入を防ぐことも必要である。 It is necessary to remove the pumice stones accumulated in the harbor, but it is also necessary to prevent the inflow by using the net.
本考案は、軽石の流入を事前に察知した時に安全、迅速、簡易に設置、撤去出来ることを課題とする。 The present invention has an object that it can be installed and removed safely, quickly and easily when the inflow of pumice stone is detected in advance.
以上の課題を解決するために請求項1の考案に係る軽石流入防止ネットはネットの周囲をテント生地で補強し、周囲４辺に固定用ハトメ(上部）、ネット連結用ハトメ(左右）、ネットの垂直を保つためのハトメ（下部）を備えたネットである。 In order to solve the above problems, the pumice stone inflow prevention net according to the invention of claim 1 is reinforced with tent fabric around the net, and the eyelets for fixing (upper part), eyelets for connecting the net (left and right), and the net are on the four sides around the net. It is a net with eyelets (bottom) to keep it vertical.
本考案によれば、ネットを設置することにより、安全迅速、簡易に設置することが出来、多くのネットを短時間で設置することが可能である。 According to the present invention, by installing the net, it is possible to install the net safely, quickly and easily, and it is possible to install many nets in a short time.
以下、本考案に係る軽石流入防止ネットの好適な設置方法について図に基づいて説明する。 Hereinafter, a suitable installation method of the pumice stone inflow prevention net according to the present invention will be described with reference to the drawings.
軽石流入防止ネット設置方法は、水に入れるネットの周囲補強布5の下部に縫い込んだチェーン等6の重りが入っている辺から水に入れ、底近くに流し込み、周囲補強布5上部に取り付けたハトメ2と生簀など養殖施設やブイなどとロープ等で固定する。流入する軽石を防ぐのに横の距離が必要な場合はもう１枚ネットを用意し、左右に付いているハトメ3同士をロープ等で結び、横の長さを調整し、深さが必要な場合は、ネット下部に付けたハトメ４とネット上部に付けたハトメ2同士をロープ等で結び縦の長さを調整できる。
To install the grommet inflow prevention net, put it in water from the side where the weight of 6 such as the chain sewn on the bottom of the net surrounding
本考案の各部材は使用目的から言って同等の働きをするものであれば素材、形状は問わない The material and shape of each member of the present invention may be used as long as they have the same function in terms of the purpose of use.
本考案で使用する軽石流入防止ネットは、水の抵抗や軽石の大きさ、設置場所を考えてネットの大きさを決める。 For the pumice inflow prevention net used in the present invention, the size of the net is determined in consideration of water resistance, the size of the pumice stone, and the installation location.
本考案は軽石流入防止ネットを設置することにより、今まで考えたこともなかった軽石流入による港湾施設等の被害を防ぐことができる By installing a pumice inflow prevention net, the present invention can prevent damage to port facilities, etc. due to pumice inflow that has never been considered before.
