Abstract

<P>PROBLEM TO BE SOLVED: To provide an extension method of underwater membrane wherein the underwater membrane extended in a settling pond or the like can keep the extended state even water is withdrawn. <P>SOLUTION: In this extension method of the underwater membrane, the underwater membrane supported with ropes is suspended from a suspension rope with both ends fixed, by support ropes. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、沈殿池等に転調する水中膜の展張方法に関する。  The present invention relates to a method for spreading an underwater film that is tuned to a sedimentation basin or the like.

従来、沈殿池等に水中膜を設ける場合水中膜にフロート等を付設して、フロートの浮力を利用して水中膜を水面下に垂設していた。
しかしながら、水が貯えられている時には問題はないが、例えば沈殿池等の清掃を行う場合、貯えられた水を一旦排水する必要がある。このように排水を行うと水中膜は、それと共に沈殿池等の底部に垂れ下がり、その結果沈殿池等の清掃が極めて困難であった。Conventionally, when an underwater film is provided in a sedimentation basin or the like, a float or the like is attached to the underwater film, and the underwater film is suspended below the surface of the water using the buoyancy of the float.
However, there is no problem when water is stored. However, when cleaning a sedimentation basin or the like, for example, it is necessary to drain the stored water once. When draining in this way, the underwater film hangs down along with the bottom of the sedimentation basin or the like, and as a result, cleaning of the sedimentation basin or the like was extremely difficult.

そこで、本発明者は、沈殿池等を清掃するような場合においても、水中膜が緊張状態を保持しているための方法について種々検討を加えた結果本発明を完成するに至った。  Therefore, the present inventors have completed the present invention as a result of various studies on methods for maintaining the tension of the underwater film even when cleaning the sedimentation basin or the like.

すなわち、本発明は、両端部を固定した懸垂支持ロープに、ロープ等で支持された水中膜を支持ロープで懸吊することを特徴とする水中膜の展張方法である。  That is, the present invention is a method for spreading an underwater film, wherein an underwater film supported by a rope or the like is suspended by a support rope on a suspension support rope having both ends fixed.

本発明方法によれば、展張した水中膜が水を抜く際にも展張状態を保持することができるので、沈殿池等の清掃等を容易に行うことができる。  According to the method of the present invention, a stretched state can be maintained even when the stretched submerged membrane drains water, so that the sedimentation basin and the like can be easily cleaned.

次に本発明方法を沈殿池の図面を参照しながら説明するが、本発明は、以下の説明のみに限定されるものではない。  Next, the method of the present invention will be described with reference to the drawing of the settling basin, but the present invention is not limited to the following description.

図１は、沈殿池の縦断面概略図である。
１は沈殿池、２は支持具、３は懸垂支持ロープ、４はロープ、５はフロート、６は水中膜、７は支持ロープを示す。FIG. 1 is a schematic longitudinal sectional view of a sedimentation basin.
1 is a sedimentation basin, 2 is a support, 3 is a suspension support rope, 4 is a rope, 5 is a float, 6 is an underwater film, and 7 is a support rope.

沈殿池１の両サイドに支持具２を固定する。この支持具２間に懸垂支持ロープ３を展張する。次に例えばフロート５に垂下した水中膜６からなる水流傾斜板（「パトレシア」日本ソリッド株式会社製商品名）をロープ４に連接したものの両端部を支持具２に固定する。この水中膜６を連設したロープ４を支持ロープ７によって懸垂支持ロープ３に懸吊する。  The support 2 is fixed to both sides of the settling basin 1. A suspension support rope 3 is stretched between the supports 2. Next, for example, both ends of a water-flow inclined plate (trade name “Patresia” manufactured by Nippon Solid Co., Ltd.) made of an underwater film 6 suspended from the float 5 are fixed to the support 2. The rope 4 provided with the underwater film 6 is suspended from the suspension support rope 3 by the support rope 7.

本発明方法に用いられる懸垂支持ロープ３、ロープ４および支持ロープ７は，紐状物、ワイヤーロープ、鎖等種々の形態のものが好適に使用できる。
また水中膜も前記したフロート付水流傾斜板の他、シート膜、網状膜、モール状膜、穴あきシート膜等の種々の形態のものが使用できる。モール状膜は炭素繊維を使用し、担持効果をもたせるものも使用できる。The suspension support rope 3, the rope 4 and the support rope 7 used in the method of the present invention can be suitably used in various forms such as a string, a wire rope, and a chain.
In addition to the above-mentioned floated water flow inclined plate, various forms such as a sheet membrane, a net-like membrane, a molding membrane, a perforated sheet membrane can be used as the underwater membrane. As the molding film, carbon fibers can be used, and those having a supporting effect can be used.

本発明方法はフロート５を水面下に沈めて水中膜を垂設したものにも使用できる。さらに、ロープ４に垂下した水中膜６を取り付け垂設しても良い。  The method of the present invention can also be used in a case in which the float 5 is submerged below the water surface and an underwater film is suspended. Furthermore, an underwater film 6 suspended from the rope 4 may be attached and suspended.
