Description

本発明は、廃棄物処理場等に用いられる排水管に関するものである。   The present invention relates to a drain pipe used in a waste treatment plant or the like.

一般的な廃棄物処理場は図３で示すように、遮水シートを配設したピット１０を造成し、廃棄物中の有機物がある場合に発生する発酵ガスを排出するガス抜き縦多孔管１１やピット１０の底に溜まる雨水や廃棄物から浸出する有害物質を含んだ汚水を排水処理場１３に排水する排水多孔管１２が配管されている。   As shown in FIG. 3, a general waste disposal site has a pit 10 provided with a water shielding sheet, and a degassing vertical perforated tube 11 for discharging fermentation gas generated when there is organic matter in the waste. A drainage perforated pipe 12 is provided for draining rainwater collected at the bottom of the pit 10 and sewage containing harmful substances leached from waste to the wastewater treatment plant 13.

しかしながら、ガス抜き縦多孔管１１や排水多孔管１２は汚泥や廃棄物の破片等で目詰まりし排気や排水作用に悪影響を及ぼし、また、排水処理場１３では有害物質を含んだ汚水の処理負荷が増大し、さらには、ガス発生による廃棄物処理場内温度が高温となり廃棄物処理場の安定化に問題があった。尚、排水多孔管内に小砂利を充填して汚水の浄化を図っているものがあるが、これは排水多孔管内の小砂利により通水を悪くしており円滑な排水性に難点を有している。
特公昭６１−２０５２５公報 特開平６−１０６１５２公報 特開平７−２９００２３公報 However, the degassing vertical perforated pipe 11 and the drainage perforated pipe 12 are clogged with sludge and waste debris, etc., and have an adverse effect on the exhaust and drainage action. Furthermore, the temperature inside the waste treatment plant due to gas generation has become high, and there has been a problem in stabilizing the waste treatment plant. Some drainage perforated pipes are filled with small gravel to purify the sewage, but this has a problem in smooth drainage due to poor water flow due to the small gravel inside the drainage porous pipe. Yes.

本発明は、このような問題点に鑑みて、廃棄物処理場内の浄化促進、廃棄物処理場内の高温化の抑制、雨水による表面水の低減を可能にし棄物処理場の安定化が図れる排水管を提供することを目的とする。   In view of such problems, the present invention enables wastewater treatment to stabilize the waste treatment plant by promoting purification in the waste treatment plant, suppressing high temperatures in the waste treatment plant, and reducing surface water due to rainwater. The purpose is to provide a tube.

本発明は、この目的を達成するために、請求項１に記載のとおり、廃棄物処理場等に用いられる排水管であって、多孔管の外周面を不織布で被覆し、この不織布の外周に隙間を有して網かごを嵌挿し、前記不織布と網かごとの間の隙間に砂利砕石あるいは小砂利を充填したことを特徴とするものである。   In order to achieve this object, the present invention is a drainage pipe used in a waste treatment plant or the like as described in claim 1, wherein the outer peripheral surface of the porous pipe is covered with a nonwoven fabric, and the outer circumference of the nonwoven fabric is covered. A mesh basket is inserted with a gap, and the gap between the nonwoven fabric and the mesh basket is filled with gravel crushed stone or small gravel.

本発明によれば、多孔管はガス抜きと水みちを確保し、多孔管の外周面に被覆した不織布は多孔管の目詰まりを防止し、不織布と網かごとの間の隙間に充填した砂利砕石あるいは小砂利は汚水濾過と通水性を向上し、網かごは転圧による崩れを防止する効果を有している。   According to the present invention, the perforated pipe ensures gas venting and water, and the nonwoven fabric coated on the outer peripheral surface of the perforated pipe prevents clogging of the perforated pipe, and gravel filled in the gap between the nonwoven fabric and the net cage. Crushed stone or small gravel improves filthy water filtration and water permeability, and the net cage has the effect of preventing collapse due to rolling pressure.

以下本発明を実施するための最良の形態について図面に基づいて説明する。図１において、１は周面に多数の孔２が開設されている多孔管である。   The best mode for carrying out the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a perforated pipe having a large number of holes 2 on its peripheral surface.

本発明は、前記多孔管１の外周面を不織布３で被覆し、この不織布３の外周に隙間を有して網かご４を嵌挿し、前記不織布３と網かご４との間の隙間に砂利砕石あるいは小砂利５を充填した構造である。前記多孔管１は高密度ポリ塩化ビニール材が適当である。   In the present invention, the outer peripheral surface of the porous tube 1 is covered with a nonwoven fabric 3, a mesh basket 4 is inserted into the outer periphery of the nonwoven fabric 3 with a gap, and gravel is inserted into the gap between the nonwoven fabric 3 and the mesh basket 4. It is a structure filled with crushed stone or small gravel. The porous tube 1 is suitably a high-density polyvinyl chloride material.

本発明は上記の通りの構造であるから、多孔管１はガス抜きと水みちを確保し、多孔管１の外周面に被覆した不織布３は多孔管１の目詰まりを防止し、不織布３と網かご４との間の隙間に充填した砂利砕石あるいは小砂利５は汚水濾過と通水性を向上し、網かご４は転圧による崩れを防止する作用効果を有する。   Since the present invention has the structure as described above, the porous tube 1 ensures gas venting and a water channel, and the nonwoven fabric 3 coated on the outer peripheral surface of the porous tube 1 prevents clogging of the porous tube 1. Gravel crushed stone or small gravel 5 filled in the gap between the mesh cage 4 improves filthy water filtration and water permeability, and the mesh cage 4 has an effect of preventing collapse due to rolling pressure.

そこで、本発明の排水管を廃棄物処理場に用いた実施例について説明する。本発明の排水管をガス抜き縦多孔管として用いる場合、廃棄物処理場の廃棄物を貫通してピットの遮水シート上に立設配置する。   Therefore, an embodiment in which the drain pipe of the present invention is used in a waste disposal site will be described. When the drain pipe of the present invention is used as a degassing vertical perforated pipe, the waste pipe at the waste disposal site is erected on the water-impervious sheet of the pit.

これにより、廃棄物から発生するガスを抜くと共に、多孔管１内に入る雨水は不織布３、砂利砕石あるいは小砂利５を通過して網かご４より廃棄物処理場内に拡散し、廃棄物処理場の底部に排水される。この時、ガス抜き縦多孔管として用いた排水管は、不織布３により多孔管１の目詰まりを防止し、砂利砕石あるいは小砂利５は泥を濾過と通水性を確保し、網かご４は廃棄物の重みによる崩れを防止してガス抜き縦多孔管の形態を維持する。   As a result, the gas generated from the waste is removed and the rainwater entering the perforated pipe 1 passes through the nonwoven fabric 3, gravel crushed stone or small gravel 5 and diffuses into the waste treatment plant from the mesh basket 4. Drained to the bottom of the. At this time, the drainage pipe used as the degassing vertical perforated pipe prevents clogging of the perforated pipe 1 by the nonwoven fabric 3, gravel crushed stone or small gravel 5 ensures filtration and water permeability, and the mesh basket 4 is discarded. Prevents collapse due to the weight of the object and maintains the shape of the degassed vertical porous tube.

一方、本発明の排水管を廃棄物処理場の底部の遮水シート上に配設し汚水を排水処理場に回収する排水管として用いる場合、廃棄物処理場の底部に溜まった汚水を網かご４より砂利砕石あるいは小砂利５及び不織布３を通過して多孔管１内に入り、前記排水処理場に排水される。この時、網かご４は廃棄物の重みによる崩れを防止し、砂利砕石あるいは小砂利５は濾過作用により汚水を極力浄化すると共に通水性を確保し、不織布３により多孔管１の目詰まりを防止する。   On the other hand, when the drainage pipe of the present invention is used as a drainage pipe that is disposed on the water-impervious sheet at the bottom of the waste treatment plant and collects the sewage into the wastewater treatment plant, the sewage collected at the bottom of the waste treatment plant can 4 passes through the gravel crushed stone or small gravel 5 and the nonwoven fabric 3 and enters the porous tube 1 and is drained to the waste water treatment plant. At this time, the mesh basket 4 prevents collapse due to the weight of the waste, and the gravel crushed stone or small gravel 5 purifies the sewage as much as possible by filtration and ensures water permeability, and the nonwoven fabric 3 prevents the porous tube 1 from being clogged. To do.

従って、ガス抜き縦多孔管と排水処理場に回収する排水管として併用することにより、廃棄物中の有機物がある場合に発生する発酵ガスを殆ど完全に分解し、ガス発生がなくなり、廃棄物処理場の高温化を抑制して地中温度が周りと変わらなくなる。また、排水処理場の底部に溜まる汚水は極力浄化されて排水処理場に回収されるので汚水の処理負荷が低減し廃棄物処理場の安定化が図れる。   Therefore, the combined use as a degassing vertical perforated pipe and a drain pipe to be collected at a wastewater treatment plant almost completely decomposes the fermentation gas generated when there is organic matter in the waste, eliminating the generation of gas and waste treatment. Suppressing the high temperature of the field prevents the underground temperature from changing. In addition, the sewage collected at the bottom of the wastewater treatment plant is purified as much as possible and collected in the wastewater treatment plant, so that the wastewater treatment load is reduced and the waste treatment plant is stabilized.

このように、本発明による排水管は、廃棄物処理場内の浄化促進、廃棄物処理場内の高温化の抑制、雨水による表面水の低減を可能にし棄物処理場の安定化を促進する環境汚染防止に有益な利点を有しているものである。   Thus, the drainage pipe according to the present invention is an environmental pollution that promotes purification in the waste treatment plant, suppresses the high temperature in the waste treatment plant, reduces surface water by rainwater, and promotes stabilization of the waste treatment plant. It has a beneficial advantage in prevention.
