Description

本発明は、地震などの緊急災害時に、避難地に設置される仮設トイレ用配管装置に関する。   The present invention relates to a piping device for a temporary toilet installed in an evacuation area during an emergency disaster such as an earthquake.

たとえば特許文献１に開示された仮設トイレ用配管構造は、地中に上流側上位から下流側下位に傾斜して埋設される排水管と、この排水管に長さ方向に所定間隔毎に接続されて上端部が地表に露出される複数の縦管と、縦管の上端部に設置された便器と、排水管の下流端に設けられたマンホールとを具備し、マンホールと既設の下水管とを接続したものである。上記従来構成では、排水管のマンホール側またはマンホール内の排水管端部にスライドゲートを取り付けている。使用に際しては、スライドゲートを閉じて排水管内に初期水を溜めておき、初期水により縦管から落下されるし尿の軟化を促進し、所定量のし尿が溜まると、スライドゲートをあけてし尿を初期水と共にマンホール側に流し、下水管に排出するものである。
特開平１１−１０７３６２号公報 For example, the temporary toilet piping structure disclosed in Patent Document 1 is connected to a drain pipe inclined in the ground from the upstream upper side to the downstream lower side, and connected to the drain pipe at predetermined intervals in the length direction. A plurality of vertical pipes whose upper ends are exposed to the ground surface, a toilet installed at the upper end of the vertical pipe, and a manhole provided at the downstream end of the drain pipe, and the manhole and the existing sewer pipe It is connected. In the above conventional configuration, the slide gate is attached to the manhole side of the drain pipe or the drain pipe end in the manhole.

上記従来構成において、スライドゲートは、操作ロッドにより平板状のゲート板を排水管内の弁座面に沿って上下にスライドさせて開閉するように構成されたもので、ゲート板は弁座面に沿って摺動されるため、弁座面にパッキングなどの止水部材を設けても止水性能が低く、また時間の経過と共に止水性能が低下しやすいものであり、このため排水管内に初期水が確実に保持されずに流出する恐れがあった。このような場合、縦管から落下されたし尿が排水管内で堆積固化して排出されず、使用不能に陥るおそれがあった。   In the above conventional configuration, the slide gate is configured to open and close by sliding a flat gate plate up and down along the valve seat surface in the drain pipe by the operation rod, and the gate plate extends along the valve seat surface. Therefore, even if a water-stopping member such as a packing is provided on the valve seat surface, the water-stopping performance is low, and the water-stopping performance tends to deteriorate over time. However, there was a risk of spilling without being securely held. In such a case, the human urine dropped from the vertical pipe is not solidified in the drain pipe and is not discharged, and there is a possibility that it cannot be used.

[Embodiment 1]

本発明は、緊急災害時などの被災地に設置される仮設トイレ用配管装置で、実施の形態を図面に基づいて説明する。
［実施の形態］
本発明に係る実施の形態を図面を参照して説明する。 The present invention is a temporary toilet piping device installed in a disaster area such as an emergency disaster, and an embodiment will be described based on the drawings.
[Embodiment]
An embodiment according to the present invention will be described with reference to the drawings.

この仮設トイレ用配管装置は、下水管に排出する中継管に、２つの弁装置を直列に配設することにより、止水性に優れ、かつ水激性を確保できるように構成したものである。
すなわち、図１，図２に示すように、地中には、上流側上位から下流側下位に一定の勾配で傾斜される排水管１が埋設され、この排水管１の上面に、長さ方向に所定間隔毎に上端部が地表に露出される複数本（図では５本）の縦管２が立設接続されている。また排水管１の下流端部には、既設の下水管（図示せず）に接続される中継管３が接続され、この中継管３に２つの弁装置４，５が直列に設けられている。 This temporary toilet piping device is configured to have excellent water-stopping properties and to ensure water-strength by arranging two valve devices in series on a relay pipe discharged to a sewer pipe.
That is, as shown in FIGS. 1 and 2, in the ground, a drain pipe 1 that is inclined with a certain gradient from the upstream upper side to the downstream lower side is buried, and the length direction is formed on the upper surface of the drain pipe 1. In addition, a plurality (five in the figure) of vertical pipes 2 whose upper ends are exposed to the ground surface at every predetermined interval are connected upright. Further, a relay pipe 3 connected to an existing sewer pipe (not shown) is connected to the downstream end of the drain pipe 1, and two valve devices 4 and 5 are provided in series on the relay pipe 3. .

前記排水管１は、ポリエチレン製で口径が４００〜６００ｍｍ程度の複数本の単管１ａを接続して所定の長さに形成されている。そしてこの排水管１は、掘削された設置溝６内に基礎砕石６ａを介してたとえば２％の一定の勾配で設置され、覆土で覆われている。   The drain pipe 1 is formed to a predetermined length by connecting a plurality of single pipes 1a made of polyethylene and having a diameter of about 400 to 600 mm. The drainage pipe 1 is installed in the excavated installation groove 6 with a constant gradient of 2%, for example, via a basic crushed stone 6a, and is covered with cover soil.

図３に示すように、前記縦管２はポリエチレン製で、サドル付き支管２ａと、この支管２ａの上部に接続された縦管本体２ｂと、縦管本体２ｂの上端を開閉自在なキャップ２ｃとを具備し、排水管１の上面に長さ方向に一定ピッチで形成された縦管用開口部１ｃに支管２ａが嵌合され、そのサドルが取付バンド２ｄにより排水管１に取り付けられている。また縦管２の上端部周囲には、開閉蓋２ｆ付きのスラブ枠２ｅが設けられ、開閉蓋２ｆとキャップ２ｃを取り外した状態で縦管本体２ｂの上部に便器７が取り付けられる。   As shown in FIG. 3, the vertical pipe 2 is made of polyethylene, and includes a saddle-equipped branch pipe 2a, a vertical pipe body 2b connected to the upper portion of the branch pipe 2a, and a cap 2c capable of opening and closing the upper end of the vertical pipe body 2b. The branch pipe 2a is fitted into the vertical pipe openings 1c formed on the upper surface of the drain pipe 1 at a constant pitch in the length direction, and the saddle is attached to the drain pipe 1 by the attachment band 2d. A slab frame 2e with an opening / closing lid 2f is provided around the upper end of the vertical tube 2, and the toilet bowl 7 is attached to the upper portion of the vertical tube main body 2b with the opening / closing lid 2f and the cap 2c removed.

排水管１の上流端部には、初期水を供給するとともに、作業員が入ってメンテナンス可能な口径のマンホール槽８が設けられており、マンホール槽８の槽本体８ａは、設置溝６内に基礎砕石６ａを介して設置され、その上面開口部にスラブ枠８ｂを介して開閉可能な開閉蓋８ｃが設けられている。   The upstream end of the drain pipe 1 is provided with a manhole tank 8 having a diameter that can supply initial water and can be maintained by workers, and the tank body 8a of the manhole tank 8 is provided in the installation groove 6. An opening / closing lid 8c that is installed via a basic crushed stone 6a and that can be opened and closed via a slab frame 8b is provided at the upper surface opening.

排水管１の下流端に管変換継手部９を介して、排水管１より小口径の中継管３が接続されている。そしてこの中継管３には、上流側に弁板４ｃを上下方向にスライドさせて中継管３を急速開放・閉鎖可能なスライドゲート弁からなる第１弁装置４が設けられるとともに、前記第１弁装置４の下流側に所定間隔をあけて、弁体５ｄを回動して弁座部５ｈに圧接し中継管３を確実に閉鎖・開放可能なバタフライ弁からなる第２弁装置５が設けられている。   A relay pipe 3 having a smaller diameter than the drain pipe 1 is connected to the downstream end of the drain pipe 1 via a pipe conversion joint portion 9. The relay pipe 3 is provided with a first valve device 4 comprising a slide gate valve capable of rapidly opening and closing the relay pipe 3 by sliding the valve plate 4c in the vertical direction on the upstream side, and the first valve A second valve device 5 composed of a butterfly valve is provided which is capable of rotating the valve body 5d at a predetermined interval on the downstream side of the device 4 to press and contact the valve seat portion 5h to reliably close and open the relay pipe 3. ing.

すなわち、前記第１弁装置４は、図４，図５に示すように、設置溝６内に基礎砕石６ａとコンクリート製の床版６ｂを介して縦置き円筒状の弁箱４ａが設置され、この弁箱４ａに中継管３が接続されている。そして弁箱４ａ内には、中継管３に連通された開閉用弁穴４ｂを全閉可能な板状の弁板４ｃと、開閉用弁穴４ｂの両側で弁板４ｃの昇降を案内するとともに弁座面を形成するガイド溝４ｄと、弁箱４ａ内で弁板４ｃを昇降駆動する操作ロッド４ｅとが設けられている。そして操作ロッド４ｅの上端部には操作用の把手４ｆが設けられている。また弁箱４ａの上方部には、開閉蓋４ｇを有するスラブ枠４ｈが設置されている。この第１弁装置４の構成では、弁板４ｃがガイド溝４ｄを摺動して開閉用弁穴４ｂを開閉するため、ガイド溝４ｄの弁座面と弁板４ｃが圧接されることがなく、このため止水性能が劣る傾向にある。一方、開閉蓋４ｇを開け把手４ｆを掴んで操作ロッド４ｅを素早く引き上げることで、弁板４ｃを短時間で引き上げて中継管３を急速開放することができる。   That is, as shown in FIGS. 4 and 5, the first valve device 4 is provided with a vertically placed cylindrical valve box 4 a installed in the installation groove 6 via a basic crushed stone 6 a and a concrete floor slab 6 b, The relay pipe 3 is connected to the valve box 4a. In the valve box 4a, a plate-like valve plate 4c capable of fully closing the open / close valve hole 4b communicated with the relay pipe 3, and the elevation of the valve plate 4c are guided on both sides of the open / close valve hole 4b. A guide groove 4d forming a valve seat surface and an operating rod 4e for driving the valve plate 4c up and down within the valve box 4a are provided. An operating handle 4f is provided at the upper end of the operating rod 4e. A slab frame 4h having an open / close lid 4g is installed above the valve box 4a. In the configuration of the first valve device 4, the valve plate 4c slides on the guide groove 4d to open and close the opening / closing valve hole 4b, so that the valve seat surface of the guide groove 4d and the valve plate 4c are not pressed against each other. For this reason, the water stopping performance tends to be inferior. On the other hand, by opening the opening / closing lid 4g and grasping the handle 4f and quickly pulling up the operating rod 4e, the relay plate 3 can be opened quickly by pulling up the valve plate 4c in a short time.

第２弁装置５は、図４，図６，図７に示すように、中継管３に介在された弁箱５ａの開閉用弁穴５ｂに、水平軸５ｃを中心に所定範囲で回動される円形の弁体５ｄを有し、水平軸５ｃの端部にはギヤボックス５ｅを介して操作軸５ｆが立設され、この操作軸５ｆの上端に操作ハンドル５ｇが設けられている。ギヤボックス５ｅと操作軸５ｆと操作ハンドル５ｇは、円筒状の外筒体５ｊ内に収容され、外筒体５ｊの上端部にはスラブ枠５ｋを介して開閉蓋５ｍが設けられている。この第２弁装置５の構成では、弁体５ｄの外周部が、開閉用弁穴５ｂの周囲に設けられた弁座部５ｈに、大きい加圧力で圧接されて弁穴５ｂを閉鎖するので、止水性能が高くかつ寿命も長い。一方、弁体５ｄの回動動作が遅く中継管３を急速開放することができない。   As shown in FIGS. 4, 6 and 7, the second valve device 5 is rotated in a predetermined range around a horizontal shaft 5c into an opening / closing valve hole 5b of a valve box 5a interposed in the relay pipe 3. A circular valve body 5d is provided, and an operating shaft 5f is erected on the end of the horizontal shaft 5c via a gear box 5e, and an operating handle 5g is provided on the upper end of the operating shaft 5f. The gear box 5e, the operation shaft 5f, and the operation handle 5g are accommodated in a cylindrical outer cylinder 5j, and an open / close lid 5m is provided on the upper end of the outer cylinder 5j via a slab frame 5k. In the configuration of the second valve device 5, the outer peripheral portion of the valve body 5 d is pressed against the valve seat portion 5 h provided around the opening and closing valve hole 5 b with a large applied pressure to close the valve hole 5 b. High water stopping performance and long life. On the other hand, the rotation of the valve body 5d is slow and the relay pipe 3 cannot be opened quickly.

また排水管１には、排水管１からオーバーフローした初期水とし尿とを下水管に排出するオーバーフロー管１０が設けられている。このオーバーフロー管１０は、上流端が管変換継手部９の閉鎖板部で初期水の水位Ｗより上方の部位に接続され、第１弁装置４を迂回した後、下流端が中継管３の第２弁装置５の下流側に接続されている。   Further, the drain pipe 1 is provided with an overflow pipe 10 for discharging initial water overflowing from the drain pipe 1 and urine to the sewer pipe. The overflow pipe 10 has an upstream end connected to a portion above the water level W of the initial water at the closing plate portion of the pipe conversion joint portion 9, bypasses the first valve device 4, and then has a downstream end connected to the first end of the relay pipe 3. It is connected to the downstream side of the two-valve device 5.

上記構成において、使用する延べ人数に応じた所定時間ごとに（ここで「所定時間」とは、予め決定された時間ではなく、使用状態やし尿の貯留状態から判断される排出を必要とする時間をいう）、まず、第２弁装置５の開閉蓋５ｍを開けて操作ハンドル５ｇを操作し、閉鎖位置の弁体５ｄを開放位置に回動させる。ついて、第１弁装置４の開閉蓋４ｇを開け、操作ロッド４ｅの把手４ｆを掴んで素早く弁板４ｃを引き上げて中継管３を急速開放する。この開放時の水激性により、排水管１内の尿は初期水と共に勢い良く中継管３に流れ込み、下水管にスムーズに排出される。   In the above configuration, every predetermined time according to the total number of people to be used (here, “predetermined time” is not a predetermined time, but a time that requires discharge determined from a use state or a stored state of human urine) First, the opening / closing lid 5m of the second valve device 5 is opened, the operation handle 5g is operated, and the valve body 5d in the closed position is rotated to the open position. Subsequently, the opening / closing lid 4g of the first valve device 4 is opened, the handle 4f of the operating rod 4e is grasped, the valve plate 4c is quickly lifted, and the relay pipe 3 is rapidly opened. Due to the water violence at the time of opening, urine in the drainage pipe 1 flows into the relay pipe 3 vigorously together with the initial water and is smoothly discharged to the sewer pipe.

排出が終わると、操作ロッド４ｅを押し込んで第１弁装置４を閉じるとともに、操作ハンドル５ｇを操作して第２弁装置５を閉じる。さらにマンホール槽８の開閉蓋８ｂを開けて、最上流位置の縦管２に対応する排水管１の水位Ｗが所定高さになるまで初期水を供給する。   When the discharge is finished, the operation rod 4e is pushed in to close the first valve device 4, and the operation handle 5g is operated to close the second valve device 5. Further, the open / close lid 8b of the manhole tank 8 is opened, and initial water is supplied until the water level W of the drain pipe 1 corresponding to the vertical pipe 2 at the most upstream position reaches a predetermined height.

上記実施の形態によれば、排水管１を既設の下水管に接続する中継管３の上流側に、急速開放可能であるが止水性能に劣るスライドゲート弁からなる第１弁装置４を設け、その下流側に止水性能は高いが、開閉動作が遅いバタフライ弁からなる第２弁装置５を設けたので、排水管１内の初期水の漏れを確実に防止することができるとともに、第２弁装置５の開放後に第１弁装置４を開放することで、中継管３を急速開放して水激性を生じさせ、排水管１内のし尿を初期水と共にスムーズに下水管に排出することができる。   According to the above-described embodiment, the first valve device 4 including the slide gate valve that can be quickly opened but is inferior in water stopping performance is provided on the upstream side of the relay pipe 3 that connects the drain pipe 1 to the existing sewer pipe. In addition, since the second valve device 5 comprising a butterfly valve that has a high water stopping performance but is slow in opening and closing operation is provided on the downstream side, it is possible to reliably prevent leakage of initial water in the drain pipe 1 and By opening the first valve device 4 after the two-valve device 5 is opened, the relay pipe 3 is quickly opened to cause water violence, and the human waste in the drain pipe 1 is smoothly discharged to the sewer pipe together with the initial water. be able to.

また排水管１の上流端に、マンホール槽８を設けたので、作業員によるメンテナンスを容易に行うことができる。
さらに排水管１と、第２弁装置５の下流側の中継管３とを接続するオーバーフロー管１０により、排水管１内でオーバーフローした初期水とし尿とをスムーズに下水管に排出することができる。 Further, since the manhole tank 8 is provided at the upstream end of the drain pipe 1, maintenance by an operator can be easily performed.
Furthermore, the overflow pipe 10 connecting the drain pipe 1 and the relay pipe 3 on the downstream side of the second valve device 5 can smoothly discharge the initial water overflowed in the drain pipe 1 and urine into the sewer pipe. .
