本考案は、滝落し可能の塩ビ製公共ますに関するものである。 The present invention relates to a PVC public masu that can be dropped.
【０００２】[0002]
滝落し可能の塩ビ製公共ますや滝落し可能のコンクリ−ト製マンホ−ルは、次 のような排水設備に採用されている。 A public masu made of PVC that can be dropped and a manhole made of concrete that can be dropped are used in the following drainage facilities.
【０００３】 （１）一般に、宅地内排水設備では、施工の経済性を考慮し、塩ビ製起点ます は最小土被り（例えば、２０ｃｍ）になるよう設置し、基準勾配（例えば、排水 管径１００ｍｍφの場合、２／１００の勾配とする）により、塩ビ製排水管を布 設して行き、既設の下水本管と接続するが、そのとき、宅地と公共地との境近傍 に既に設置されている塩ビ製公共ますを介して接続する。(1) Generally, in the drainage facility in a residential land, considering the economical efficiency of construction, the PVC starting point is installed so as to have the minimum overburden (for example, 20 cm), and the reference slope (for example, the drainage pipe diameter is 100 mmφ). In case of 2), the PVC drainage pipe is installed and connected to the existing sewer main, but at that time, it has already been installed near the boundary between the residential land and the public land. Connect via a public masu made of PVC.
【０００４】 かかる塩ビ製公共ますは、従来、宅地内の排水管に比べ相当に低い位置（公共 地の配管は５０ｃｍ〜１ｍの埋設深さ）に流入・流出口があり、かつ、予め流入 口と流出口とは成形されているので、その流入口へ、順次勾配を整えた宅地内の 塩ビ製排水管を接続する場合、狭小地等により配管延長がとれない場合には、す なわち、塩ビ製公共ますの流入口が宅地内の塩ビ製排水管の下流端より低い位置 にある場合には、その落差を解消するため、例えば、実公昭６２−９４１９号公 報中第５図で示されているようなドロップますを介在させている。Conventionally, such a PVC public masu has an inflow / outflow port at a position considerably lower than a drainage pipe in a residential land (the piping of the public land is a burial depth of 50 cm to 1 m), and the inflow port is previously provided. Since the outlet and the outlet are molded, when connecting a PVC drainage pipe in a residential land with a graded slope to the inlet, if the pipe cannot be extended due to a small area, that is, If the inlet of the PVC public mast is located lower than the downstream end of the PVC drainage pipe in the residential area, in order to eliminate the drop, for example, see Fig. 5 in the publication No. 62-9419. The intermediary of a drop muzzle as described above is intervening.
【０００５】 （２）また、周知のように地表勾配が急な場合には、管きょ内の流速の調整と 、下流側の最小土破りを保つため、また、上流側の掘削深さを節減するため地表 勾配に合せた段差接合が行なわれている。かかる段差接合には、副管付のコンク リ−ト製マンホ−ルを用いている。(2) Also, as is well known, when the surface gradient is steep, the flow velocity in the pipe can be adjusted and the minimum soil breakage on the downstream side is maintained, and the excavation depth on the upstream side is adjusted. In order to save energy, step junctions are used according to the ground slope. For such step joining, a manhole made of concrete with a secondary pipe is used.

【考案が解決しようとする課題】 前記従来技術（１）では、塩ビ製公共ますの上流側にドロップますを必要とす る。[Problems to be Solved by the Invention] In the above-mentioned conventional technique (1), it is necessary to provide a drop masu on the upstream side of the PVC public masu.
【０００７】 前記従来技術（２）では、下水道本管にも塩ビ管が用いられながら段差接合用 の塩ビ製小口径マンホ−ルは存在しない。という問題があった。In the prior art (2), although a PVC pipe is also used as the main sewer pipe, there is no PVC small-diameter manhole for joining steps. There was a problem.

本考案を添付図面に示す実施例により詳細に述べる。 図１および図２において、本実施例の塩ビ製公共用会所ます（単に公共ますと もいう）の点検筒１は、１本の、例えば径３００ｍｍφの塩ビ製パイプで本体１ ａを構成し、その下端側には、上げ底高さＨ（例えば１００ｍｍ）を介して、流 出管２（すなわち、流出管部）を点検筒１から突出させて生産工場で溶接して取 付ける。 The present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. In FIG. 1 and FIG. 2, an inspection cylinder 1 of a PVC public hall (also simply referred to as a public masu) of this embodiment comprises a main body 1a of one PVC pipe having a diameter of 300 mmφ, for example. The outflow pipe 2 (that is, the outflow pipe portion) is protruded from the inspection pipe 1 via the raised bottom height H (for example, 100 mm), and is welded and attached to the lower end side of the inspection pipe 1.
【００１０】 この上げ底高さＨは、稜線を中心として弯曲された外向きフランジ４を一端に もち、かつ、該フランジ４の稜線と直交したゴム輪受口をもつ９０°支管３の該 フランジ４の稜線の張出し長さＬに略等しくしている。この流出管２は約１６５ mm φの塩ビ製短パイプで構成され、その基部外周にはＦＲＰをオ−バレイ１１し て補強している。この点検筒１の上端には掃除口用蓋１０が取付けられる。This raised bottom height H has an outward flange 4 which is curved around the ridgeline at one end, and which has a rubber ring receptacle orthogonal to the ridgeline of the flange 4 of the 90 ° tributary pipe 3. Is approximately equal to the overhanging length L of the ridgeline. This outflow pipe 2 is about 165 mm It is composed of φ short pipe made of PVC, and FRP is overlaid on the outer periphery of the base to reinforce it. A cleaning port lid 10 is attached to the upper end of the inspection tube 1.
【００１１】 点検筒１の下端側には、凹状弯曲面をもつ上げ底（底部）５が溶接または接着 等により、前記上げ底高さＨをもって設けられ、この上げ底５と下端板６とで形 成される上げ底空間には、充填材７が充填されている。この充填材７には砂や発 泡ウレタンが用いられる。したがって、この上げ底５と前記流出管２とでインバ −ト部材を構成する。A raised bottom (bottom portion) 5 having a concave curved surface is provided on the lower end side of the inspection cylinder 1 with the raised bottom height H by welding or bonding, and is formed by the raised bottom 5 and the lower end plate 6. The filling material 7 is filled in the raised bottom space. Sand or foaming urethane is used for the filler 7. Therefore, the raised bottom 5 and the outflow pipe 2 constitute an invert member.
【００１２】 以上のような点検筒１を現場に設置した後、この点検筒１の側壁に、現場に合 せて、つまり滝落し落差および水平方向を合せて流入管８の流入口９を穿設する 。但し、この流入口９の高さは最大約６０cm以内のものにすることが好ましい。 この流入口９の外周面を取り囲んで９０°支管３のフランジ４を接着剤で取付け る。したがって、この接着接合は、９０°支管に無理な力が作用せず、設計どお りの接合となって信頼性を損なわない。したがって、この実施例の公共用会所ま すは、滝落し配管専用のものとなる。After the inspection cylinder 1 as described above is installed on the site, the inlet 9 of the inflow pipe 8 is formed on the side wall of the inspection cylinder 1 in line with the site, that is, by adjusting the waterfall head and the horizontal direction. Set up. However, it is preferable that the height of the inflow port 9 be within a maximum of about 60 cm . The flange 4 of the 90 ° branch pipe 3 is attached with an adhesive so as to surround the outer peripheral surface of the inflow port 9. Therefore, in this adhesive bonding, an unreasonable force does not act on the 90 ° branch pipe, and the bonding is as designed, and reliability is not impaired. Therefore, the public hall of this embodiment is dedicated to the downfall piping.
【００１３】[0013]
本考案によれば、 １）滝落し可能の会所ますを、底部および流出管部からなるインバ−ト部材と 、１本の点検筒とで構成したので、これを射出成形しようとすれば、きわめて大 型の金型を必要として生産コストを上げるが、点検筒を既製の塩ビパイプで構成 し、これに、底部および流出管部からなるインバ−ト部材を生産工場で接合して 取付けたので、きわめて安価な滝落し可能の会所ますにすることができる。 According to the present invention, 1) the meeting place which can be dropped is composed of an invert member consisting of a bottom part and an outflow pipe part, and one inspection tube. Although a large mold is required to increase the production cost, the inspection tube is made of a ready-made PVC pipe, and the invert member consisting of the bottom part and the outflow pipe part is joined and attached at the production plant. It can be a very cheap waterfall hall.
【００１４】 ２）流入口を施工現場に合せて穿設して、ゴム輪受口をもつ９０°支管を接着 接合するので、滝落し落差の高さや水平方向の向きを無理なく、現場に正確に合 せることができ、ひいては、傾斜地の勾配に変化があっても、１種の公共ますで 足りると共に、施工が確実に可能となり、施工の信頼性が向上する。2) The inlet is drilled according to the construction site, and the 90 ° branch pipe with the rubber ring receiving port is adhesively bonded, so the height of the waterfall and the horizontal direction can be adjusted without difficulty. Therefore, even if there is a change in the slope of the sloping land, one type of public suffices will be sufficient, and the construction will be possible reliably, and the construction reliability will be improved.
【００１５】 ３）流入口の穿設や９０°支管の接合は、簡単な作業ですむことから、滝落し 可能のコンクリ−ト製公共ますや副管付のコンクリ−ト製マンホ−ルに比べ、本 考案の公共ますの施工はきわめて簡単にすむ。3) Since drilling of the inlet and joining of the 90 ° branch pipes are simple work, compared to concrete masu made of concrete that can drop a waterfall and manhole made of concrete with an auxiliary pipe. The construction of the public trout of the present invention is extremely easy.
【００１６】 ４）宅地内の排水管の下流端と公共ますの流入口との落差をなくする、従来の ドロップますを必要としない。4) It eliminates the need for the conventional drop hood, which eliminates the drop between the downstream end of the drainage pipe in the residential land and the inlet of the public mast.
【００１７】 すなわち、公共ますに本考案の塩ビ製公共ますを用いると、前記落差を点検筒 の穿設する流入口の位置によって解消することができる。That is, when the PVC public masu of the present invention is used in the public masu, the drop can be eliminated by the position of the inflow port where the inspection tube is bored.
【００１８】 ５）地表の勾配の急な所に配管する方式、すなわち、段差接合方式における副 管付コンクリ−ト製マンホ−ルの代りに用いることができる。5) It can be used in place of the manhole made of concrete with auxiliary pipe in the method of piping at a steep slope of the ground, that is, in the step joining method.
【００１９】 ６）宅地内における既設のガス管や水道管がある場合に、これを避けて、これ らの下方に布設する排水管用の段差用会所ますに代用することができる。6) If there is an existing gas pipe or water pipe in the residential area, it is possible to avoid it and substitute it for the step hall for drainage pipes installed below them.
