Abstract

PURPOSE:To miniaturize a merged treating septic tank, an independent treating septic tank and the other various septic tanks. CONSTITUTION:A plurality of tanks are aligned and provided backward and forward or right and left by concrete walls. A septic tank is miniatured by providing a middle slab 2 to the space part of the upper part of a tank low in the water level WL of the septic tanks. This septic tank is vertically split and a control chamber tank 3 is formed on the middle slab 2 and thereby miniaturization of the septic tank is realized.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a septic tank applicable to various septic tanks such as a combined treatment septic tank and a single treatment septic tank.

0002

2. Description of the Related Art Conventional septic tanks usually have a plurality of tanks 6 lined up front to back and left and right with concrete walls, and a slab 7 is provided on top of each tank to form a control room tank 8, as shown in FIG. A blower and other equipment are installed in this management room tank, and management openings 9 are provided in the slab 7 corresponding to each tank 8.

0003

[Problem to be solved by the invention] The problem to be solved is that since the treatment tank and the control room tank are arranged one above the other, the entire septic tank becomes large and costly, and especially in the case of an underground type. , the amount of excavation is large, and the wall thickness of the septic tank needs to be set sufficiently to accommodate the earth pressure and water pressure.

0004

[Means for Solving the Problems] The septic tank of the present invention has a plurality of tanks lined up front to back or left and right by concrete walls, and is divided into upper and lower parts by providing an intermediate slab in the upper space of the tank where the water level of the septic tank is low. The size of the septic tank was realized by forming the control room tank on the intermediate slab.

[0005]

[Function] According to the septic tank with the above configuration, an intermediate slab is provided in the upper space of the tank with the lowest water level among the multiple tanks arranged in a row, and the control room tank is formed above it, so the overall height of the septic tank is lower than that of the conventional one. In addition, since most of the septic tank can be managed from the ground, it is possible to significantly save labor for lighting and ventilation equipment, achieving the objectives of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a plan view of an embodiment of a septic tank according to the present invention, and FIG. 2 is a sectional view taken along line A--A in FIG.

The septic tank of the present invention is made of precast, concrete, or cast-in-place concrete, as is well known, and has a plurality of tanks 1 arranged front to back or left and right by concrete walls.

Among the plurality of tanks 1 arranged in a row, the tank 1 with a low water level
An intermediate slab 2 is provided in the upper space of the tank to form a divided tank 1A divided into upper and lower parts, and a management chamber tank 3 is formed above the slab 2. An entrance 4 is established on the ceiling of the control room tank 3, and a staircase or ramp 5 is provided between the entrance 4 and the intermediate slab 2, or an entrance is established in the side wall and a staircase or ramp is provided from the ground surface to the entrance. It has been done.

It goes without saying that the septic tank of the present invention can be applied to any of the underground, above-ground, and semi-underground types.

[0009]

[Effect of the invention] As explained above, the septic tank of the present invention has
Among the multiple tanks arranged in a row, an intermediate slab is installed in the upper space of the septic tank with a low water level to form a divided tank divided into upper and lower parts.
Since the control room tank is formed above the intermediate slab, the overall height of the septic tank can be significantly reduced compared to conventional septic tanks, and cost reductions can be realized. In addition, when applied to an underground type, the amount of excavation is reduced by the reduction in the height of the septic tank, labor-saving work is achieved, and the object of the invention is achieved.
