JPH0533895U - Septic tank for easy horizontal confirmation - Google Patents

Abstract

(57) [Summary] [Purpose] To make it easy to check the horizontality of the septic tank body during and after burial. [Structure] A level (8) is fixed to an appropriate place on the upper surface of the partition plate (6) and other walls of the septic tank body (1).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a septic tank capable of easily confirming whether or not it is horizontal when it is buried in the ground or after it is buried.

[0002]

[Prior Art]

 Except for very large septic tanks, usually septic tanks that are manufactured in advance in factories are embedded in the ground and installed for use. At this time, if the septic tank is not properly kept horizontal, the purifying function of the sewage will deteriorate, and the bubbles will not rise correctly evenly over the entire surface of the septic tank, so the aeration effect will also decrease.

[0003] Therefore, when the septic tank is inserted into a hole dug into the ground and installed, a level is applied to an appropriate position on the upper edge of the septic tank, and the septic tank is visually maintained while being held, so that the septic tank is properly kept horizontal. Thus, the burying work is performed. The same applies to the inspection after installation.

[0004]

[Problems to be solved by the device]

 While burying the septic tank or after installing it, it is troublesome and inefficient to check the level by holding the level with each hand and abutting it on the proper position on the upper edge of the septic tank. It is dangerous because the posture is forced.

[0005]

[Means for Solving the Problems]

 According to the present invention, the above-mentioned problems can be solved by attaching a spirit level to a proper place on the upper surface of the septic tank body.

[0006]

[Action]

 You can check the level of the septic tank main body without having to manually put the level on the septic tank main body.

【Example】

 The figure shows an embodiment of the invention.

In FIGS. 1 and 2, (1) is a septic tank main body, which is manufactured in advance in a factory or the like by, for example, FRP. The septic tank body (1) has an inflow pipe (2) on one side, an outflow pipe (3) on the other side, and appropriate partition plates (4) (5) (6) and a fumarolic pipe (7) inside. Etc., and the specific structure of itself is not directly related to the present invention, so further description will be omitted.

An omnidirectional bubble level (8) is fixed to the upper edge of an appropriate partition plate, in the embodiment, the last partition plate (6). This level (8) is installed so that the air bubbles come to the center when the main body (1) of the septic tank is kept correctly and horizontally.

The mounting procedure of the electronic level (8) is shown in FIGS. 3 and 4.

In FIG. 3, a horizontal holding tool (10) protrudingly provided on the rear surface of a locking piece (9) having a downward U-shaped cross section, which is fitted and locked to the upper edge of the partition plate (6), is shown. A circular spirit level (8) is properly fitted into the vertical bottomed hole (11) on the upper surface, and is fixed with an adhesive or the like.

In FIG. 4, the circular spirit level (8) is dropped into the vertical bottomed hole (13) of the rear-facing holder (12) fixed to the rear surface of the upper end of the partition plate (6), and the bottomed hole ( Since the screw ring (15) is screwed into the threaded portion (14) to be provided on the upper part of the inner surface of the level (13), the spirit level (8) is pressed and held.

FIG. 5 shows an example in which two rod-shaped spirit levels (16) and (16) are mounted orthogonally. The retainer (17) has a rearward supporting piece (19) projectingly provided on the rear surface of a locking piece (18) having a downward U-shaped cross section that can be fitted to the upper edge of the partition plate (6) from above, and Elongated bottomed holes (20) (21) orthogonal to each other are provided on the upper surfaces of the locking piece (18) and the support piece (19). The spirit level (16) is fitted and fixed in each bottomed hole (20) (21), and the locking piece (18) is fitted and attached to the upper edge of the partition plate (6).

In any of the above cases, the bottomed holes (11), (13), (20) and (21) have their postures so that the spirit level fitted and fixed in them may be properly leveled. Needless to say, and the shape is defined.

The level is not necessarily attached to the upper edge of the partition plate but may be attached to the upper surface of the side wall of the septic tank body.

In addition, the holder may be omitted, and the bottomed hole may be formed on the upper surface of the wall body of the septic tank main body, that is, the side wall or the partition wall, and the spirit level may be fitted therein.

[0017]

[Effect of the device]

 (a) Since it is not necessary to apply the level with each hand, workability is good and it is safe.

(B) There is no risk of making an error in the confirmation of the levelness of the septic tank body due to the contact point of the level or improper holding.

(C) Even after installation, it is possible to easily confirm whether the septic tank main body is inclined or deformed.
