Description

  The present invention relates to a water gate opening / closing jig for a manhole with a water storage gate.

In recent years, plans to bury drainage facilities in advance in places where many people gather, such as schools and parks, have been promoted so that temporary toilets can be temporarily installed in preparation for disasters such as earthquakes and events.
As shown in FIG. 5, the conventional temporary toilet drainage system joins the vertical pipe 2 and the vertical pipe 2 to make the fluid flow down according to the number of toilet bowls B installed on the ground and the installation position, and the vertical pipe 2. Drainage horizontal pipe 3 buried in the ground so as to collect and discharge the fluid toward a sewer pipe (not shown), and drainage horizontal pipe 3 in manhole 4 to which one end of drainage horizontal pipe 3 is connected. Is formed by providing a water storage gate 5 that opens and closes the pipe line R at the edge P and stores or discharges the fluid in the drainage horizontal drawing pipe 3. The water storage gate 5 has a gate valve 5a that opens and closes the conduit of the drainage horizontal draw pipe 3, an operation rod 5b that operates the gate valve 5a, and an operation handle 5c, and is manually opened and closed (for example, Patent Document 1) below.
When the temporary toilet 6 is not required, the drainage equipment A is configured such that the upper end opening 2a of the vertical pipe 2 is tightly closed with a lid material (not shown), and the lid is installed in the case of temporary installation of the temporary toilet 6. The temporary toilet 6 can be installed on the ground G by removing the material and opening the upper end opening 2 a of the vertical pipe 2.

  When the temporary toilet 6 is installed and the above drainage facility A is used, the water storage gate 5 is normally closed in order to efficiently use water stored in a water storage tank (not shown). At a timing at which a fixed amount of fluid is stored in the drainage horizontal draw pipe 3, the fluid is released once to several times a day.

By the way, when the drainage equipment A discharges the fluid stored in the drainage horizontal drawing pipe 3, the lid 7 of the manhole 4 having a large load is opened and a hand is put in the manhole 4 or an operator puts the manhole 4 in the manhole 4. The operation handle 5c of the water storage gate 5 must be operated by directly entering the inside. This work is usually performed by ordinary users such as city staff and school staff who manage the temporary toilet.
However, a person other than a specialist who is unfamiliar with the wastewater treatment in the manhole 4 opens the cover material 7 of the manhole 4 with a large load with a dedicated jig and bends in the vicinity of the opening or enters the manhole 4 to be constant. It was not easy to keep the water storage gate 5 open in the same posture for a time, and there was a problem that it was avoided by the user.
In addition, while holding the water storage gate 5 in an open state, the odor from the drainage horizontal pipe 3 is easily sucked, so that there is a problem that the work is painful.
Then, in view of the said subject, this invention makes it a subject to provide the opening-and-closing jig of the water storage gate which can operate the water storage gate provided in the manhole easily.
