Description

[Detailed Description of the Invention] The present invention relates to a container for growing plants that also serves as a cover for an inspection port in underground facilities such as sewage treatment facilities and sewage pipes, and a support thereof.

Conventionally, iron manhole covers have been used for inspection of underground sewage treatment facilities, sewage pipes, etc.

However, iron manholes have a strong image of being a cover for a sewage facility, which is not desirable in terms of environmental beautification and effective use of the facility. However, this was becoming a problem.

The present invention was developed in view of the above points, and instead of the conventional iron manhole cover, a container made of FRP or other synthetic resin is used for the inspection opening of the treatment tank, etc., and soil is placed in the container to hold flowers or flowering plants. The purpose of this project is to beautify the environment near sewage treatment facilities or sewage pipe manholes installed on the side of roads and make them places of relaxation by cultivating such plants.

Embodiments will be described in detail below with reference to figures showing examples.

FIG. 1 is a longitudinal cross-sectional view of the container A, in which the bottom wall 1 is provided with many holes 2 for drainage or ventilation, and the upper end of the side wall 3 has an upper edge rib 4 folded outward and downward. is established,
A backing 5 made of a resilient material such as rubber is fitted or adhered to the inside of the rib.

The planar shape of the container A is circular or rectangular to match the shape of the inspection port.

FIGS. 2 to 4 are cross-sectional views of a container A, a container support B, and a state in which they are installed in an inspection port C of a processing tank or the like.

In the example shown in FIG. 2, the upper surface of the structure 7 such as a processing tank is made almost equal to the upper surface of the container A, and the support body B that matches the diameter of the inspection port C is attached to the structure 7 such as the processing tank using an anchor bolt 6.
The upper edge rib 4 of the container A is placed and fixed on the upper end of the support B.

When container A and support B of the present invention are installed in this way, and soil is placed in container A and plants are planted, the odor emitted from the treatment tank etc. will be discharged into the container from the hole 2 in the bottom wall 1 of the container. The odor is deodorized by the soil in the container and clean gas is discharged into the atmosphere.

Since the packing 5 is provided at the contact area between the container A and the support B, odor or bubbles are not emitted or released into the atmosphere from the contact area.

The hole 2 serves as a drainage hole for water when watering plants or for rainwater, which seeps into the underground facility.

In the example shown in FIGS. 3 and 4, the height of the support B is increased,
The top surface of container A is made higher than the top surface of construct 7.

Figure 5 shows yet another example, in which the container A and support B of the present invention are installed in a facility where the sewage treatment facility is not a new facility, but an old facility where an iron manhole cover is used for the inspection opening. This is an example of application.

In this case, a gasket 9 is placed on the grooved manhole receiving part 8 of the inspection opening from which the iron manhole cover has been removed, a support body B is placed on top of the gasket 9, and a container A is further set on the support body B.

FIG. 6 shows an application example of the container A of the present invention in which the support B is not used.

In this case, a horizontal step 10 is provided at the bottom of the side wall 3 of the container A so that the bottom wall protrusion slightly enters the inspection opening, and the backing 9 installed in the manhole receiving part 8 of the inspection opening is attached to the side wall of the container. The lower surface of the horizontal stepped portion 10 is placed thereon.

The container A of the present invention needs to have sufficient rigidity so that it can deform and fall into the processing tank through the inspection port C, and for this purpose, the wall thickness of the container must be adjusted appropriately, and the It is also necessary to appropriately provide reinforcing ribs (not shown).

Alternatively, the lower end of the support body B is made to protrude outward in a buckwheat shape,
The support body B may be fixed by driving an anchor bolt into the collar-shaped portion vertically to the underground facility.

[Brief explanation of the drawing]

Figure 1 is a longitudinal sectional view of container A, and Figures 2 to 5 are container A.
Fig. 6 is a cross-sectional view showing the state in which the container A and the support B are installed in the inspection port of a processing tank, etc., and Figure 6 is a cross-sectional view showing the state in which the container A is used without using the support B. In the figure, 1 is the bottom wall, 2 is the through hole, 3 is the side wall, 4 is the upper flange, 5 is the packing, 6 is the fixing fitting, 1 is the structure, 9 is the packing, A is the container, B is the support, C indicates each inspection port.

Claims (1)

[Scope of utility model registration request] A container A has a bottom wall provided with an appropriate number of drainage holes or ventilation holes, a side wall having an upper edge rib whose upper end is folded back, and a backing material installed in the upper edge rib, and the upper end is in close contact with the backing material. A container for plant growth which also serves as a cover for an inspection port of an underground facility, and its support, which is made of a combination of a cylindrical container support B having an opening at the top and bottom and whose side or lower end is in close contact with the wall of the inspection port of an underground facility. .
