Abstract

PURPOSE:To obtain a changeover socket for changing over drainage paths in prepared waste water treatment facilities for emergency when the drainage paths of a public toilet in a park, etc., are damaged by an earthquake, etc. CONSTITUTION:A changeover socket for a drainage path is formed in structure having a bottomed vertical cylinder section 2 having an opening in an upper section, an on-normalcy duct 3 protruded from the vertical cylinder section to the left and the right so as to be communicated through the vertical cylinder section 2, an on-emergency duct 4 protruded in one direction from the vertical cylinder section 2 on the lower side of the on-normalcy duct 3, a closing door 5 closing the on-emergency duct 4 from the vertical cylinder section 2, and an operating means 6 for pulling up the closing door 5 to the upper side through the opening of the vertical cylinder section 2. When the closing door 5 is pulled up by the operating means 6 at the time of emergency, the flow of waste water is changed over from the on-normalcy duct 3 to the on-emergency duct 14.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an emergency drainage treatment facility prepared in advance when the drainage route of a public toilet such as a park, which is an evacuation site in the event of a disaster such as an earthquake, is damaged by the disaster. The present invention relates to a drainage path switching socket used in the case of switching.

[0002]

2. Description of the Related Art In the event of a disaster such as an earthquake, local governments have designated parks as evacuation sites. Naturally, many evacuees will gather at this evacuation site in the event of a disaster, but if public toilets are unavailable at that time, it will be extremely inconvenient for the evacuees. In addition to the destruction of the public toilet itself, the reason why the public toilet cannot be used in the event of a disaster is damage to the water supply or sewerage. In case of damage to the sewer, prepare a wastewater treatment facility for emergency use in advance, guide the wastewater to this wastewater treatment facility for treatment, and use the treated water as flush water for the toilet. It is possible to take emergency measures.

From this point of view, some local governments are considering the installation of wastewater treatment facilities for emergency use and are proceeding with specific designs. Regarding this, there are no problems because various types of wastewater treatment facilities have been known so far, but there is still no such example for switching the drainage route during normal times to the drainage route during emergency situations, which is an urgent task. It is left as.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is provided for emergency use prepared in advance when a drainage route of a public toilet such as a park is damaged by a disaster. The purpose is to provide a switching socket for switching the drainage route to the wastewater treatment facility.

[0005]

A switching socket according to the present invention has a bottomed vertical cylindrical portion having an opening at the top and a normal state in which the vertical vertical portion protrudes from the vertical cylindrical portion so as to communicate with each other. Pipes, emergency pipes that project from the vertical cylinder in one direction below the normal pipes, closed doors that close the emergency pipes from the vertical pipes, and opening of the closed doors in the vertical pipes. It has an operation means for pulling it up through the.

[0006]

This switching socket is used by being installed at the bottom of the manhole with the normal time pipe line connected to the normal time drainage route and the emergency time pipe line connected to the emergency drainage route. And in normal times, drainage is flowing through the normal-time drainage path to the normal-time drainage path, but in an emergency, if you open the manhole cover and operate the operating means to pull up the closing door, A certain emergency line is opened, and drainage naturally flows into the emergency line and the drainage route can be switched. In other words, according to this switching socket, the drainage path can be switched by a simple operation such as pulling up the closing door.

[0007]

EXAMPLE An example of the present invention will be described below. As shown in FIGS. 1 and 2, the switching socket 1 according to the present embodiment is centered on a bottomed vertical cylindrical portion 2 having an opening at the top, and from this vertical cylindrical portion 2 to the normal time conduits 3 and 3 and emergency. It has a structure in which the hour pipe 4 is provided in a protruding manner.

The two normal times pipelines 3 and 3 are provided so as to be aligned with each other at the intermediate height position of the vertical tube portion 2, while the emergency time pipeline 4 is provided in the normal times pipelines 3 and 3. The lower side is projected in a direction intersecting the directions of both the normal times pipelines 3 and 3 at a right angle, and the openings 3 of the both normal times pipelines 3 and 3 with respect to the vertical cylindrical portion 2 are provided.
The openings 3w and 3w do not overlap with the opening 4w of the emergency conduit 4 with respect to the vertical cylindrical portion 2 in terms of level.

Then, the vertical cylindrical portion 2 is blocked transversely at a level sandwiched between the upper side of the opening 4w of the emergency conduit 4 and the lower sides of the openings 3w, 3w of the both normal conduits 3,3. Closed door 5
Is provided. More specifically, the closing door 5 is provided with a communication recess 5p transversely recessed, and the communication recess 5p is formed.
Therefore, both normal times of the pipelines 3 are directly communicated with each other. Further, the closing door 5 is fixed to the vertical tube portion 2 by painting the periphery thereof by caulking. Therefore, the closing door 5 surely prevents the drainage from flowing into the emergency conduit 4 at the time of normal operation, and secures the smooth flow of the drainage between the normal conduits 3 and 3 (arrow in FIG. 1). it can.

An operating handle 6 is attached to the closing door 5 as an operating means.
It can be pulled away from the vertical tube portion 2 by pulling it up. Here, the operation handle 6 is provided at a position deviated from the center of the closing door 5, so that the surrounding caulking can be easily peeled off at the time of separation.

As shown in FIG. 3, the switching socket 1 as described above has both normal time pipelines 3 and 3 connected to the normal drainage path N.
It is used by being installed at the bottom of the manhole M in a state where the emergency conduit 4 is connected to the emergency drainage path E. Then, in an emergency, the manhole M lid (not shown) is opened, the operation handle 6 is pulled upward, and the closing door 5 is pulled up.
Then, the emergency conduit 4 is opened to switch the drainage path, and the drainage flows to the emergency drainage path E through the emergency conduit 4 as indicated by the arrow in FIG. Incidentally, T in FIG. 3 is a toilet, U is a sewer, and S is a simplified wastewater treatment facility.

[0012]

As described above, the switching socket of the present invention ensures a smooth drainage flow during normal operation,
In an emergency, it is possible to switch the drainage route reliably with a simple operation, which can contribute to the implementation of an emergency system for a toilet whose drainage route has been damaged in a disaster.
