Abstract

PROBLEM TO BE SOLVED: To provide a method that is available as a toilet in the event of a disaster even in a permeation tank.SOLUTION: A permeation tank of the present invention is the permeation tank provided underground and made by water-permeable concrete. The permeation tank is provided as follows: a valve capable of being interrupted from the part above the ground is provided in an inflow port of rainwater to the permeation tank; also, air vent piping and toilet seat mounting piping are provided in the top surface of the permeation tank; both are opened on the surface of the earth, and the valve is interrupted in the event of a disaster; a water-proof bag is inserted from an opening of the toilet seat mounting piping; an entrance portion of the water-proof bag is formed of a hard member and a body section of the water-proof bag being put in the inside of the permeation tank inside is formed of flexible materials; the bag is expanded with an inflow of fluid materials to serve as a manure storage part; and a toilet seat is installed after the insertion of the water-proof bag to thereby serve as an emergency toilet.SELECTED DRAWING: Figure 2

Description

The present invention belongs to a technique in which a permeation tank made of osmotic concrete for controlling the outflow of rainwater or the like is used as a disaster toilet.

The storage space is formed by arranging a plurality of aquifers underground, and the storage space is covered with a water shielding sheet, and the partition is partitioned and part of it is temporarily stored as a toilet for disaster. This method is proposed by our company. Japanese Unexamined Patent Application Publication No. 2009-041204 partitions and uses a storage tank, and Japanese Unexamined Patent Application Publication No. 2009-185484 uses a human hole as a toilet.

The present invention proposes a method that can be used as a toilet even in a permeation tank in the event of a disaster.

The present invention is a permeation tank made of permeable concrete provided in the basement, provided with a valve that can be shut off from the ground at the inlet of rainwater etc. to the permeation tank, and attached to the upper surface of the permeation tank with an air vent pipe and toilet seat Piping pipes are provided, both open to the ground, shut off the valve in the event of a disaster, and a water shielding bag is inserted through the toilet seat mounting pipe opening, and the entrance portion of the water shielding bag is formed of a rigid member. The body part of the water-impervious bag that enters the inside of the infiltration tank is made of a flexible material, expands as the fluid flows in, becomes a manure storage part, and is attached to the toilet seat after insertion of the water-impervious bag and becomes an emergency toilet It is a tank.

The present invention uses the osmosis tank to expand the bag body as the stool is inserted and manure is stored in the bag body even when rainwater or the like is present in the tank. It can be used because rainwater penetrates the ground.
The valve prevents the inflow of rainwater when used with a toilet.

These are the conceptual diagrams of the penetration tank used for this invention. These are the conceptual diagrams which show the state which changes from an osmosis tank to a toilet.

Hereinafter, the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the infiltration tank used in the present invention is constructed of water-permeable concrete, and is provided with a valve that can block inflow of rainwater and the like. Further, an air vent pipe opened on the ground and a pipe for attaching a toilet seat are provided.
In the figure, the air vent pipe is provided so as to accompany the toilet seat mounting pipe, but it may be located at a position where air between the permeable concrete wall and the bag body can escape when the bag body described later is inflated.

FIG. 2 shows a procedure for changing the permeation tank into a toilet.
FIG. 2a shows a state in which the bag is inserted into the tank.
FIG. 2b shows a state in which the toilet seat is attached.
FIG. 2c shows a state in use as a toilet.
The entrance of the bag body needs to be formed of a hard material having a large diameter so that the inflowing manure does not adhere to and clog the inside of the pipe.
The excrement reservoir, which is the main body of the bag, is formed of a flexible and water-proof material and must swell in accordance with the amount of inflow.

Usually, it can be used as a rainwater outflow control facility, and can be used as a toilet in the event of a disaster.

Claims (1)

This is a seepage tank made of permeable concrete in the basement, and a valve that can be shut off from the ground is provided at the inlet of rainwater to the seepage tank, and an air vent pipe and a toilet seat mounting pipe are provided on the top surface of the seepage tank Both open to the ground surface, shut off the valve in the event of a disaster, and a water-impervious bag is inserted from the toilet seat mounting pipe opening, and the entrance part of the water-impervious bag is formed of a hard member inside the infiltration tank. The main part of the water-impervious bag that enters is an infiltration tank that is formed of a flexible material and expands with the inflow of fluid to become a manure storage part, and after the insertion of the water-impervious bag, a toilet seat is attached.
