Description

The present invention relates to a joint with a drainage device such as a non-return valve and a drainage basin system including the joint, and particularly to a joint inserted between the inverted portion of the basin and the frame portion of the lid and the drainage basin system. In the connecting portion of the inverting part and the joint, the position of the inflow port of the joint equipped with a drainage device by cutting the connecting port of either the inverting part or the joint into a spigot whose length can be adjusted Easily adjustable fittings (especially height) and basin systems containing such fittings.

In general, the drainage pipes connected to each drainage system are used to mitigate sudden changes in the amount of wastewater discharged from toilets and other drainage facilities, or for the purpose of removing and inspecting foreign objects such as garbage. The wastewater collected in the drainage basin is collected in the drainage basin installed in the residential lot, and the wastewater collected in the drainage basin is discharged to the sewage main via the public basin or the manhole.

However, due to abnormal weather in recent years, there have been frequent cases in which a large amount of rainwater has flowed into the sewer main pipe in a short period of time. There is a problem that overflowing wastewater flows back through a drain basin or the like, and the backflowing wastewater spouts out from an indoor drainage system connected to a drain pipe.

For this reason, in order to prevent the backflow of wastewater from the sewage main pipe from overflowing from the indoor drainage equipment through a drainage basin or the like, for example, as described in Japanese Patent Laid-Open No. 2006-283547 (Patent Document 1) In addition, anti-backflow devices have been developed that are attached to the inlet of the basin.

However, the backflow prevention device described in Patent Document 1 is based on the premise that it is attached to the inlet of the inverted portion of the drain basin. For this reason, if the position (especially height) of the inlet of the invert section differs from the position (especially the height) of the external drainage pipe to be connected, a wide area around the drainage basin will be excavated and the external drainage will be adjusted to match the height of the inlet. There was the problem of having to lay out the tubes.

On the other hand, in order to solve the above problems, for example, as described in Japanese Patent Application Laid-Open No. 11-269976 (Patent Document 2), a riser pipe extending in the height direction is connected to the upper opening of the invert portion. A multi-basket has been developed in which the side wall of the riser pipe is narrowed with a hole saw or the like so that the inlet can be retrofitted according to the position (especially the height) of the external drain pipe.

However, in the case of the multi-trough described in Patent Document 2, after burying, the side wall of the riser pipe is aligned with the position of the external drainage pipe and narrowed using a hole saw or the like, and furthermore, the inflow port is added around the drainage basin. There was also the problem that a large area had to be excavated, and the installation work for the drainage basin was also large-scale. In addition, since the backflow prevention device must be installed after the inflow port is retrofitted to the multi-basket, there is a problem that the installation work of the drainage device must be carried out in an extremely narrow space inside the multi-basket.

In order to solve the problem that the multi-masu described in Patent Document 2 has, for example, Japanese Patent Application Laid-Open No. 6-229009 (Patent Document 3) discloses a masu main body provided with an outflow port and an invert, and the masu It has a pipe material connected to the upper socket of the main body, and a joint member having a lower socket connected to the pipe material and an inlet. By cutting the length of the pipe material, A drain basin is disclosed in which the height of the inlet of the joint member connected to the upper part thereof can be adjusted to the height of the external drain pipe.

However, in the drain basin described in Patent Document 3, a cuttable pipe material must be prepared and connected to the basin body in order to enable the height adjustment of the inlet of the joint member, which is laborious and costly. I had a hang problem. In addition, since the drainage basin described in Patent Document 3 does not plan to attach a backflow prevention device to the inflow port, it is necessary to process the inflow port of the joint member if a backflow prevention device is to be newly installed. I had a problem.

Furthermore, in the drainage basin described in Patent Document 3, if the lid is to be installed according to the level of the ground, the height of the frame and the lid connected to the top is adjusted by cutting the length of the pipe material. There was the problem that a second pipe material had to be prepared and connected between the frame supporting the lid and the joint member in order to be ground level. In particular, in the drainage basin described in Patent Document 3, the upper connection port of the basin body and the upper and lower connection ports of the joint member are shaped as sockets in order to increase the degree of freedom in assembling each part. If you put it away, you will not be able to secure the receiving height (lap allowance with the spigot) necessary for connection and adhesion. Therefore, there is a problem that a dedicated pipe material whose length can be adjusted by cutting must be prepared and used separately from the container body, the joint member and the frame body.
