【発明の詳細な説明】 〔産業上の利用分野〕 この発明は分流式下水道のマンホールに関し、特にた
とえば狭小道路下に埋設される分流式下水道のマンホー
ルに関する。The present invention relates to a split sewer manhole, and more particularly to a split sewer manhole that is buried under a narrow road, for example.
従来の分流式下水道では、汚水用および雨水用流路は
それぞれ独立して形成され、それに伴ってマンホールも
それぞれの流路毎に必要であった。そのため、道路幅が
或る程度以上必要となり、たとえば4m以下の狭小道路に
おける下水道整備がなかなか進まなかった。In the conventional sewage sewer system, channels for sewage and rainwater are formed independently, and accordingly, manholes are also required for each channel. For this reason, the road width needs to be a certain amount or more, and for example, sewerage development on narrow roads of 4 m or less has been slow to progress.
そこで、実開昭63−81954号（第１図〜第12図）で
は、１つのマンホールに汚水用流路および雨水用流路を
通すようにした分流式下水道が提案されている。この分

が汚水用流路とされ、上側空間が雨水用流路とされる。In view of this, Japanese Utility Model Laid-Open No. 63-81954 (FIGS. 1 to 12) proposes a split sewer system in which one manhole is provided with a sewage channel and a rainwater channel. This sewage sewer manhole has an invert formed at the bottom of the skeleton or housing at the site, and the inside of the skeleton or housing is divided into upper and lower parts by a partition plate, and the lower space is used as a wastewater flow path. The upper space is used as a rainwater flow path.

性が悪いという問題点があった。[Problems to be Solved by the Invention] In this conventional split-flow sewer manhole,
Since one manhole can control the rainwater flow path and the sewage flow path, it has become possible to install it on a narrow road, but the inversion of the sewage flow path must be formed in the manhole by mortar etc. However, there was a problem that the workability was poor.
それゆえに、この発明の主たる目的は、施工性を向上
できる。分流式下水道のマンホールを提供することであ
る。Therefore, the main object of the present invention is to improve workability. It is to provide a manhole for the sewer system.

とがインバートユニットの蓋等によって隔てられる。The case and the invert unit are separately prepared, and the invert unit is installed at the bottom of the case. Since the invert unit is provided with an invert and a lid for sealing the upper opening of the invert in advance, it is only necessary to install the invert unit at the bottom of the housing, and the sewage flow path having the invert at the bottom of the housing is installed. Can be formed. Since the rainwater sewer pipe is attached to the housing side surface above the invert unit through the fourth opening, the space above the invert unit serves as the rainwater flow path, and the wastewater flow path and the rainwater flow path are inverted. Separated by the lid of the unit.
点検に際しては、筐体の上部開口からインバートの蓋
の上に降り、まず、雨水用下水道管を、次いで、蓋を外
して汚水用下水道管を点検すればよい。At the time of inspection, it suffices to descend from the upper opening of the housing onto the lid of the invert, first check the rainwater sewer pipe, and then remove the lid and inspect the dirty water sewer pipe.
この発明によれば、筐体の底部にインバートユニット
を設置するだけでインバートを有する汚水用流路を簡単

ト20の上方に開口24aおよび24bが形成される。Referring to FIG. 1A and FIG. 1B, the split sewer manhole 10 of the present invention includes a casing 14 having a substantially rectangular planar shape with an opening 12 formed in an upper portion thereof. A plurality of steps 16 for an operator to move up and down in the housing 14 are attached to one side surface in the width direction of the housing 14, and at the bottom of the housing 14,
Inverting unit 20 which will be described later in detail via the spacer 18.
Is installed. Further, on both inner side surfaces in the length direction of the housing 14,
Openings 22a and 22b are formed in the lower portion, and openings 24a and 24b are formed above the invert unit 20.

面に密着するような幅に設定される。The invert unit 20 includes an invert 26 having a substantially U-shaped inner surface shape, and a substantially plate-shaped lid receiving portion 30 having an inspection opening 28 at a substantially central portion is formed on an upper portion of the invert 26. . Then, a substantially rectangular lid 32 made of, for example, FRP is attached to the lid receiving portion 30 so as to seal the opening 28. Here, the length of the invert unit 26 is set such that both longitudinal end surfaces of the invert unit 26 and the lid receiving portion 30 are in close contact with the inner surface of the housing 14, and the width of the invert unit 26 is The width of both ends of the portion 30 in the width direction is set to be in close contact with the inner surface of the housing 14.

される。This invert unit 20 is connected to the housing via the spacer 18.
When installed at the bottom of 14, the openings 34a and 34b at both longitudinal ends of the invert 26 and the openings 22a and 22b of the housing 14 communicate with each other.

されることはない。Then, sewerage sewers 36a and 36b are attached to the lower openings 22a and 22b of the housing 14, and rainwater sewer pipes 38a and 38b are attached to the upper openings 24a and 24b. Therefore, the sewage flows through the space (dirt water flow path) A in the invert unit 20, and the rainwater flows through the space (rain water flow path) B above the invert unit 20. Since the opening 28 of the invert unit 20 is sealed by the lid 32, the wastewater in the wastewater passage A and the rainwater in the rainwater passage B are not mixed.
この実施例によれば、筐体14の底部にインバートユニ
ット20を設置するだけで筐体14の底部にインバート26を

向上できる。According to this embodiment, the sewage flow path A having the invert 26 at the bottom of the housing 14 can be easily formed by simply installing the invert unit 20 at the bottom of the housing 14, thus improving workability.
また、汚水用流路と雨水用流路とを垂直方向に並置し
たので、筐体14すなわちマンホール10全体の幅を狭くで
きる。Further, since the sewage channel and the rainwater channel are arranged side by side in the vertical direction, the width of the housing 14, that is, the entire manhole 10 can be narrowed.
さらに、上に雨水を流し、下に汚水を流すようにした
ため、点検その他に際して、汚水で汚れることが少な
い。Furthermore, since rainwater is made to flow above and sewage is made to flow below, it is less likely to be contaminated with sewage during inspection or other purposes.
