(57) [Summary] [Purpose] The present invention is a pollution prevention fence used to prevent the spread of polluted water used during dredging. A fouling prevention fence characterized in that an upper sheet-like membrane and a lower sheet-like membrane provided on a float are made into a floating state by a connecting tool so as to be integrated in the vicinity of the water surface.
Description
【０００１】[0001]
本考案は水中に布設して汚濁水の拡散等を防止するための汚濁防止フェンスに 関する。 The present invention relates to a pollution prevention fence that is laid in water to prevent the spread of polluted water.
【０００２】[0002]
従来の汚濁防止フェンスはフロートに一枚のシート状膜を垂下したものであっ た。 しかしながらフロートに設けられたシート状膜は波浪等により破損する欠点が あった。 Conventional pollution control fences consisted of a single sheet of film suspended on a float. However, the sheet-like film provided on the float has a drawback that it is damaged by waves or the like.
【０００３】[0003]
本考案者は、これら従来のように波浪等によってもシート状膜が破損しない方 法について種々研究を重ねた結果、本考案を完成するに至った。 The present inventor has completed the present invention as a result of various researches on the method of preventing the sheet-like film from being damaged by the wave or the like as in the past.
【０００４】[0004]
すなわち、本考案はフロートに設けられた上部シート状膜と下部シート状膜と を水面近傍部において連結具によって遊動状態にして一体としたことを特徴とす る汚濁防止フェンスである。 That is, the present invention is a pollution prevention fence characterized in that the upper sheet-like membrane and the lower sheet-like membrane provided on the float are made to be in a floating state by a connecting tool in the vicinity of the water surface and integrated.
【０００５】 次に本考案の汚濁防止フェンスについて図面を参照しながら詳細に説明する。 図１は本考案に係る汚濁防止フェンスの正面図である。フロート１に上部シー ト状膜２を垂設し、該上部シート状膜２の下端部に多数の連結具３によって下部 シート状膜４の上部とを連合し一枚のシート状膜を構成する。Next, the pollution prevention fence of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of a pollution prevention fence according to the present invention. An upper sheet-like membrane 2 is vertically provided on the float 1, and a lower end portion of the upper sheet-like membrane 2 is joined with the upper portion of the lower sheet-like membrane 4 by a plurality of connecting tools 3 to form one sheet-like membrane. .
【０００６】 上部シート状膜２と下部シート状膜４との連合部は汚濁防止フェンスを水中に 布設したときに水面下５０ｃｍ〜２ｍ程度の位置が好ましい。The joint portion of the upper sheet-shaped film 2 and the lower sheet-shaped film 4 is preferably located at a position of about 50 cm to 2 m below the water surface when the pollution prevention fence is installed in water.
【０００７】 上部シート状膜２および下部シート状膜４は、シート膜あるいはメッシュ状膜 のいずれでも使用できる。そしてこれらは例えば上部シート状膜２がシート膜で 構成され、下部シート状膜４がメッシュ状膜で構成されている場合、あるいは上 部シート状膜２がメッシュ状膜で構成され、下部シート状膜４がシート膜で構成 されていてもよい。さらには両者がシート状膜あるいはメッシュ状膜であっても よい。As the upper sheet-like film 2 and the lower sheet-like film 4, either a sheet film or a mesh film can be used. These are, for example, when the upper sheet-like film 2 is formed of a sheet film and the lower sheet-like film 4 is formed of a mesh-like film, or when the upper sheet-like film 2 is formed of a mesh-like film and the lower sheet-like film is formed. The film 4 may be a sheet film. Further, both may be a sheet-shaped film or a mesh-shaped film.
【０００８】 連結具としては特に制限されるものではなく種々の構造のものが使用できる。 ただし連結具で連合した部分で少なくとも下部シート状膜４が折れ曲がるような 遊動状態となることが好ましい。 また下部シート状膜４の下端部には平板状の重錘５を設けることが好ましい。The connecting tool is not particularly limited and various structures can be used. However, it is preferable that at least the lower sheet-shaped membrane 4 is in a floating state in which the lower sheet-shaped membrane 4 bends at the portion joined by the connecting tool. Further, it is preferable to provide a flat weight 5 on the lower end of the lower sheet-shaped film 4.
【０００９】 本考案の汚濁防止フェンスの幅は一ユニツトが例えば１ｍ〜２０ｍ程度のもの を調製し施工目的に合わせて適宜選択して使用すればよい。また２０ｍ幅のよう に幅が広い場合は、フロート１は小型のものを複数個設けて垂下させることもで きる。これらの汚濁防止フェンスは多数連接して設けることによって所期の目的 が達成される。As for the width of the pollution prevention fence of the present invention, one unit having a width of, for example, about 1 m to 20 m may be prepared and appropriately selected and used according to the construction purpose. When the width is wide, such as 20 m, a plurality of small floats 1 can be provided and drooped. The intended purpose can be achieved by installing a number of these pollution prevention fences in series.
【００１０】[0010]
本考案によれば垂下膜が上部シート状膜２と下部シート状膜４に分割され、且 つその連合部が遊動状態に連結されているので仮に高い波浪等によっても下部シ ート状膜４は連結具３部を基点として遊動状態を示すために直接フロート１と上 部シート状膜２との連結部分に力が集中しないので、この部分で破損することを 防止することができる。 According to the present invention, the drooping membrane is divided into the upper sheet-shaped membrane 2 and the lower sheet-shaped membrane 4, and the joint portion is connected in a floating state, so that the lower sheet-shaped membrane 4 may be temporarily moved even by high waves. In order to show a floating state with the connecting part 3 as a base point, the force is not directly concentrated on the connecting part between the float 1 and the upper sheet-shaped membrane 2, so that it is possible to prevent damage at this part.
