これらの排水ますの敷設においては、排水管と同様に地中に埋設されるが、その埋設に際しては、排水ますの埋設位置の特定、特に、深さの調整が施工の上でのキーポイントとなる。すなわち、排水ますの埋設に際しては、インバート部材の排水管接続部と、それに接続する排水管との心合わせや、蓋部表面を地表面(GL)に面合わせをすることが重要で、さらには、枝管接続部の排水枝管との心合わせも重要なことである。   When laying these drainage basins, they are buried in the ground in the same way as drainage pipes. However, when burying them, specifying the location of the drainage basins, especially adjusting the depth, is a key point in construction. Become. That is, when embedding drainage basins, it is important to align the drain pipe connection part of the invert member and the drain pipe connected to it, and to make the surface of the lid part face the ground surface (GL). It is also important to align the branch pipe connection with the drain branch pipe.

そのためには、埋設箇所の掘削深さを調整するとともに、インバート部材と立上がり管を別部材とし、埋設箇所において、排水管の埋設深さなどの状況に応じて、立上がり管を切断して埋設位置の調整、すなわち、排水管との心合わせや地表面(GL)との面合わせを行っている。   For this purpose, the excavation depth of the buried part is adjusted, and the invert member and the riser pipe are separated from each other, and the riser pipe is cut at the buried part according to the situation such as the buried depth of the drain pipe.

In addition, in the figure, the same site | part is fundamentally displayed with the same code | symbol.

図1において、排水ます1は、相対する側壁にそれぞれ排水本管2,2を連結したインバート部材3と、このインバート部材3の上部に形成された立上がり部4に接続される、円筒状の立上がり管主体からなる点検部材5と、この点検筒5の上部開口に装着される蓋部6とから構成されるものである。なお、前記点検筒5は、家庭などからの汚水を排水本管2に流すための排水枝管15が取付けられるもので、その取付け手段にはなんら制限はないものである。また、前記蓋部6は、より具体的には、前記点検筒5の上部に外嵌される蓋受枠部7と、この蓋受枠部7に開閉自在に装着される蓋8とからなるものである。   In FIG. 1, a drainage basin 1 is a cylindrical riser connected to an invert member 3 having drainage mains 2 and 2 connected to opposite side walls, and a riser 4 formed at the top of the invert member 3. The inspection member 5 is mainly composed of a pipe, and the lid 6 is attached to the upper opening of the inspection cylinder 5. The inspection cylinder 5 is provided with a drainage branch pipe 15 for flowing sewage from a home or the like to the drainage main pipe 2, and there is no limitation on the attaching means. More specifically, the lid portion 6 includes a lid receiving frame portion 7 fitted on the upper portion of the inspection cylinder 5 and a lid 8 attached to the lid receiving frame portion 7 so as to be freely opened and closed. is there.

かかる構成の排水ます1は、通常、埋設設置箇所の現場において、排水管の埋設深さ、排水枝管の位置等を考慮して設置されるもので、排水枝管との心合わせや地表面(GL)との面合わせのため、主として点検筒5を所要長さに切断し、さらには他の部材、たとえば、図1には示されていない前記のアジャスタや、前記蓋部受枠7を切断して長さ調節をして、埋設位置を調整することにより行なっている。   The drainage basin 1 having such a structure is usually installed at the site of the burial installation site in consideration of the burial depth of the drainage pipe, the position of the drainage branch pipe, and the like. (GL) For the surface alignment, the inspection cylinder 5 is mainly cut to a required length, and further, other members such as the adjuster not shown in FIG. 1 and the lid receiving frame 7 are cut. The length is adjusted to adjust the burying position.

その際、排水ます1の概略の位置調整は、使用する立上がり管からなる点検筒5の切断により行ない、微調整は前記螺子を用いることにすると、部材の種類を少なくすることができ、より効率的な作業が可能となる。   At that time, the rough position adjustment of the drainage basin 1 is performed by cutting the inspection cylinder 5 made of the rising pipe to be used, and the fine adjustment is performed by using the screw, so that the number of types of members can be reduced and the efficiency can be improved. Work becomes possible.

前記インバート部材3の立上がり部4や、点検筒5などの各部材に設けられる螺子については、大きさや形状に格別の制限はなく、多条螺子や角螺子などの螺子も用いることができるものである。また、図1においては、前記点検筒5はインバート部材3の立上がり部4に内嵌させ、点検筒5の外周面と立上がり部4の内周面にそれぞれ螺子を設けてあるが、その嵌合状態を逆にして、点検筒5の内周面と立上がり部4の外周面に螺子を設ける形態とすることもできる。   There are no particular restrictions on the size and shape of the screws provided on the rising portion 4 of the invert member 3 and the inspection cylinder 5, and a screw such as a multi-thread screw or a square screw can also be used. is there. In FIG. 1, the inspection cylinder 5 is fitted into the rising portion 4 of the invert member 3, and screws are provided on the outer peripheral surface of the inspection cylinder 5 and the inner peripheral surface of the rising portion 4. The state may be reversed, and a screw may be provided on the inner peripheral surface of the inspection tube 5 and the outer peripheral surface of the rising portion 4.

さらに、前記蓋受枠部7と点検筒5との嵌合面にも螺子を設けることにより、蓋8と地表面(GL)との面合わせを容易に行なうことができる。   Further, by providing a screw on the fitting surface between the lid receiving frame portion 7 and the inspection cylinder 5, the lid 8 and the ground surface (GL) can be easily aligned.

図3に示す排水ます11は、図3で明らかなように、相対する壁面にそれぞれ排水本管2,2を連結したインバート部材3の上部に設けた立上がり部4に、長さの短い立上がり管主体12を連結するとともに、排水枝管15を接続するための接続部14を有するアジャスタ13とで点検筒5を構成したものであって、蓋受枠部7とアジャスタ13、アジャスタ13と立上がり管主体12などの嵌合面についても、前記と同様に螺子を設けることができ、それらにより、地表面(GL)との面合わせ、更には排水枝管との心合わせなどを、容易にすることができる。   As shown in FIG. 3, a drainage trough 11 shown in FIG. 3 has a short riser pipe in a rising part 4 provided on an upper part of an invert member 3 having drainage main pipes 2 and 2 connected to opposite wall surfaces. The inspection cylinder 5 is constituted by the adjuster 13 having the connecting portion 14 for connecting the main body 12 and connecting the drainage branch pipe 15, and the lid receiving frame portion 7, the adjuster 13, the adjuster 13, and the rising pipe main body. As for the fitting surface such as 12, a screw can be provided in the same manner as described above, thereby facilitating the surface alignment with the ground surface (GL) and the centering with the drainage branch pipe. it can.

この排水ます11は、排水枝管15を取付け接続するための接続部14が設けられたアジャスタ13を、立上がり管主体12と蓋受枠部7との間に有するもので、この排水ます11には、排水枝管15から流入する排水の流路を制限し、また、流れ方向を変えるための内副管16が設けられている。   This drainage basin 11 has an adjuster 13 provided with a connection part 14 for attaching and connecting a drainage branch pipe 15 between the rising pipe main body 12 and the lid receiving frame part 7. An inner auxiliary pipe 16 is provided for restricting the flow path of the drainage flowing from the drainage branch pipe 15 and changing the flow direction.

さらに、この排水ます11は、アジャスタ13を立上がり管主体12に内嵌する形態を有し、図4で明らかなように、アジャスタ13の下端部外周面に螺子が形成され、この螺子に螺合するリング体17がアジャスタ13の外周部に設けられているものである。したがって、前記の螺子同士を噛合させながら、リング体17を回転させると、リング体17が上下方向に移動し、アジャスタ13と立上がり管主体12の嵌合部の増減、すなわち、アジャスタ13の位置(高さ)を任意に決定することができ、地表面(GL)との面合わせ、さらには排水枝管15との心合わせなどが、煩雑な作業を伴わずに、簡単に行なうことができ、かつ微調整も容易にできるのである。   Further, the drainage basin 11 has a configuration in which the adjuster 13 is fitted into the rising pipe main body 12, and as is apparent from FIG. 4, a screw is formed on the outer peripheral surface of the lower end of the adjuster 13, and the screw is engaged with the screw. A ring body 17 is provided on the outer periphery of the adjuster 13. Therefore, when the ring body 17 is rotated while meshing the screws, the ring body 17 moves in the vertical direction, and the increase / decrease of the fitting portion between the adjuster 13 and the rising pipe main body 12, that is, the position of the adjuster 13 ( (Height) can be arbitrarily determined, and the alignment with the ground surface (GL) and the alignment with the drainage branch pipe 15 can be easily performed without complicated operations. In addition, fine adjustment can be easily performed.

また、前記と同様に、概略調整は、立上がり管主体12、アジャスタ13、さらには蓋受枠部7などの切断により行ない、微調整は上記リング体17を利用することにすると、部材の種類を少なくすることができ、より効率的な作業が可能となるのである。   Similarly to the above, the rough adjustment is performed by cutting the riser main body 12, the adjuster 13, and the lid receiving frame portion 7 and the fine adjustment is performed using the ring body 17. This makes it possible to work more efficiently.

さらに、アジャスタ13とリング体17に設けられる螺子については、大きさや形状に格別の制限はなく、多条螺子や角螺子などの螺子も用いられる。また、図3においては、アジャスタ13を立上がり管主体12に内嵌させ、アジャスタ13の下端部の外周面に螺子を設けてあるが、その嵌合状態を逆にして、立上がり管主体12の上端部の外周面に螺子を設け、それに螺合するリング体17を設ける形態とすることもできる。   Further, the screws provided on the adjuster 13 and the ring body 17 are not particularly limited in size and shape, and a screw such as a multi-thread screw or a square screw is also used. In FIG. 3, the adjuster 13 is fitted into the rising pipe main body 12 and a screw is provided on the outer peripheral surface of the lower end portion of the adjuster 13, but the fitting state is reversed and the upper end of the rising pipe main body 12 is reversed. A screw may be provided on the outer peripheral surface of the portion, and a ring body 17 that is screwed to the screw may be provided.

さらに、蓋受枠部8の下端部とアジャスタ13の上端部、立上がり管主体12の下端部とインバート部材3の立上がり部4の嵌合面にも、同様な措置を取ることができ、蓋部7と地表面(GL)との面合わせを容易に行なうことができる。   Further, similar measures can be taken for the lower end portion of the lid receiving frame portion 8 and the upper end portion of the adjuster 13, the fitting surface of the lower end portion of the rising pipe main body 12 and the rising portion 4 of the invert member 3, and the lid portion 7. And the ground surface (GL) can be easily aligned.

なお、螺子を用いて、前記部材同士を嵌合させる際には、図4に示すように、嵌合面にシール性を付与するためにシールリング18を用いることが望ましく、シールリング18により嵌合部の液密性が維持され、排水の漏洩が防止される。さらに、それら部材同士を螺子を用いて嵌合させた際も、従来の嵌合でも採用されている、接着剤を併用し、液密をより完全なものにすることもできる。   When the members are fitted to each other using screws, it is desirable to use a seal ring 18 to provide a sealing property to the fitting surface as shown in FIG. The liquid tightness of the joint is maintained and the leakage of drainage is prevented. Furthermore, even when these members are fitted together using screws, an adhesive that is also used in conventional fitting can be used in combination to make liquid tightness more complete.
