Description

さらに、図1に示すように、通水孔26の排水1が自然流入するマンホール18側の排水導入口に、ごみを除去する粗ごみフィルタ21が配置され、マンホール18内へ流入する排水1の粗ごみが取り除かれる。この粗ごみフィルタ21は、マンホール18の側壁に深さ(上下)方向に伸びるように配置されたガイドレール25によってスライド可能に保持され、所定位置に導かれて配置される。マンホール18の脇の陸上には、清掃時に粗ごみフィルタ21を吊り上げて移動させる吊上治具22が設けられる。ガイドレール25および吊上治具22がフィルタ移動手段に相当する。このフィルタ移動手段によって、粗ごみフィルタ21がマンホール18から陸上へ引き揚げられて異物除去などのメンテナンスが行われる。この点においても、潜水作業は必要なく、メンテナンス性が向上していることが分かる。 Further, as shown in FIG. 1, a coarse dust filter 21 for removing dust is disposed at the drainage inlet on the side of the manhole 18 where the drainage 1 from the water passage 26 naturally flows, and the wastewater 1 flowing into the manhole 18 is disposed. Coarse garbage is removed. The coarse filter 21 is slidably held by a guide rail 25 disposed on the side wall of the manhole 18 so as to extend in the depth (up and down) direction, and is guided to a predetermined position. On the land next to the manhole 18, a lifting jig 22 that lifts and moves the coarse filter 21 during cleaning is provided. The guide rail 25 and the lifting jig 22 correspond to filter moving means. By this filter moving means, the coarse dust filter 21 is lifted from the manhole 18 to the land, and maintenance such as foreign matter removal is performed. Also in this respect, it is understood that the diving work is not necessary and the maintainability is improved.

図6は、本発明の実施の形態2の放水口水モニタと比較するための比較例で、上述の実施の形態1の陸上ポンプ6の代わりに水中ポンプ14を使用し、放水路2内の流水中に採水口を配置してサンプリングを行う状態を示している。図6の構成では、水中ポンプ14は、マンホール18内で上下方向に伸びるガイド管13内に保持され、その内部に沿って吊り下げられて排水1中に設置される。水中ポンプ14の先端には、ごみを吸入しないようにフィルタ41が直付けされる。水中ポンプ14は、フレキシブルホース16を中継して吸入配管17に接続される。なお、上述の実施の形態1の場合は、陸上ポンプ6が測定建屋110内に設置されていたが、この実施の形態2の構成では、水中ポンプ14を用いるため、陸上ポンプを配置する必要はない。 FIG. 6 is a comparative example for comparison with the outlet water monitor of the second embodiment of the present invention, in which the submersible pump 14 is used instead of the above-described land pump 6 of the first embodiment, The state which has sampled by arrange | positioning a sampling port in flowing water is shown. In the configuration of FIG. 6, the submersible pump 14 is held in a guide tube 13 extending in the vertical direction in a manhole 18, suspended along the inside thereof, and installed in the drainage 1. A filter 41 is directly attached to the tip of the submersible pump 14 so as not to suck dust. The submersible pump 14 is connected to the suction pipe 17 through the flexible hose 16. In the case of the above-described first embodiment, the land pump 6 is installed in the measurement building 110. However, in the configuration of the second embodiment, since the submersible pump 14 is used, it is necessary to dispose the land pump. Absent.

このように、この実施の形態2の放水口水モニタでは、サンプリング手段は、マンホール18内の排水1を、マンホール18内に配置された水中ポンプ14によって、マンホール18の水面下に配置された採水口(フィルタ41配置部分と同じ。)からフレキシブルホース16を介してマンホール18外へ汲み出す構成である。図6の比較例の構成と比べても、本実施の形態2の放水口水モニタによれば、危険を伴う流水中での潜水作業から作業者を解放することができる。 As described above, in the water outlet water monitor of the second embodiment, the sampling means uses the water outlet 1 disposed below the surface of the manhole 18 by the submersible pump 14 disposed in the manhole 18 for the drainage 1 in the manhole 18. It is the structure pumped out of the manhole 18 via the flexible hose 16 (same as the filter 41 arrangement | positioning part). Compared with the configuration of the comparative example of FIG. 6, according to the outlet water monitor of the second embodiment, the operator can be released from diving work in dangerous running water.

また、この実施の形態2の放水口水モニタは、サンプリング手段として水中ポンプ14を用いることで、水の泡への耐性が強いことはすでに述べたが、さらに、実施の形態1と同様に、排水1をマンホール18内に導入することにより、排水中の泡の量を著しく減少させることができ、ポンプの負荷を軽減させられるので、ポンプの信頼性を一層向上させることが可能である。さらに、支持架台24はマンホール18内に配置され、一部が静止水中に設置されるため、速い流水中に設置した場合に比べて部材の物量を大幅に低減させられると共に、強度計算が簡素となり、設置コストが低減できるという効果も得られる。 In addition, although the outlet water monitor of the second embodiment has already been described as having strong resistance to water bubbles by using the submersible pump 14 as a sampling means, the drainage 1 is further discharged as in the first embodiment. By introducing it into the manhole 18, the amount of foam in the drainage 1 can be remarkably reduced and the load on the pump can be reduced, so that the reliability of the pump can be further improved. Furthermore, since the support frame 24 is disposed in the manhole 18 and a part thereof is installed in still water, the amount of members can be greatly reduced as compared with the case where it is installed in fast running water, and the strength calculation is simplified. The effect that the installation cost can be reduced is also obtained.
