The lower slab version, the lower mount version, the upper mount version, and the upper slab version are manufactured in a factory so that they can be assembled separately.

(Function) Since the lower slab version, lower mount version, upper mount version, and upper slab version are manufactured separately in the factory, these parts are precisely manufactured under strict quality control at the factory. It can be shaped and transported to the site, where a lower slab slab is laid on the bottom side of the burial trench, a lower pedestal slab is erected on the top side, and a septic tank, etc. is cut on top of this upper pedestal slab. Then, the upper slab plate is integrated with the lower frame plate, the septic tank is fixed by the lower frame plate and the upper frame plate, and the upper slab plate is laid on the upper surface of the upper frame plate. A septic tank or the like can be installed in a well-buried manner on the lower surface side, and the work can be done very easily.

(Example) Hereinafter, one embodiment of the present invention will be described based on the drawings.

Fig. 1 is a perspective view of a septic tank C installed with each constituent member. A pair of lower slabs 1 and 2 can be laid on the upper side of this foundation. These lower slab plates 1 and 2 are factory-produced PC plates (precast concrete plates), and are formed into a rectangular shape with a considerable length, with groove-shaped fitting grooves 1a and 2a in the center. are formed respectively.

After the lower slab plates 1 and 2 are laid, a plurality of lower stand plates 3 and 3.3 are erected on the lower slab plates 1 and 2 at appropriate intervals. That is, the fitting protrusions 3c l 3 C', -rlff provided in the fitting grooves 1a, 2a of the lower slab plates 1 and 2 and protruding from above onto the lower surface of the lower pedestal plate 3 are placed in the lower pedestal plate, avoiding one person. 3, 3.3 can be erected.

In the center of each of the lower mount plates 3, 3.3, upwardly opened arcuate receiving surfaces 3a, 3a, 3a are formed, respectively. It is formed in advance to match the outer peripheral shape of the lower surface of the septic tank C, and after the plurality of lower mount plates 3, 3.3 are erected at appropriate intervals, the plurality of lower mount plates 3, 3. A septic tank C is placed on the circular arc receiving surface 3a of each frame plate 3, 3.3.

A septic tank C is placed in the shape of a base in 3a and 3a.

In addition, connecting recesses 3b, 3b, 3b are formed on both sides of the upper end of each lower pedestal plate 3 and open upward in a stepped manner.

After the septic tank C is installed, an upper frame plate 4 is erected and fixed integrally with the lower frame plate 3 from above. That is, L mount version 4
has a symmetrical shape with the lower pedestal plate 3, and a connecting protrusion 4b that can be fitted into the connecting recess 3b is formed protruding from its lower end. , an upper mounting plate 4 is integrally erected above the lower mounting plate 3.

At this time, an arcuate receiving surface 4a formed in an arc shape at the center of the upper mounting plate 4 comes into contact along the outer peripheral surface of the upper surface of the installed septic tank C, and is sandwiched between the lower mounting plate 3 and the upper mounting plate 4. The septic tank C is fixed in this state.

Incidentally, the upper mounting plates 4 do not have to be erected on all the lower mount plates 3, and the number of upper mount plates 4 required for strength is erected on the lower mount plates 3.

After the upper mounting plates 4, 4.4 are installed, upper slab plates 5, 6 are laid on the upper surface side thereof. The upper slab plates 5 and 6 are formed in substantially the same shape as the lower slab plates 1 and 2, and the upper slab plates 5 and 6 have a manpole Ca protruding from the top of the septic tank C, Ca, Ca is 1
An opening is formed into which the manhole Ca can be inserted.

The manhole Ca can be installed with its opening facing the ground surface, and the installation is completed by attaching a cover member to each manhole Ca from above. In this state, the upper surfaces of the upper slabs 5 and 6 are exposed to the ground surface, and can be used, for example, in a parking lot.

In this example, the lower slab version 1.2, the lower mounting version 3, the upper mounting version 4, and the upper slab versions 5 and 6 are each made of a PC board or other material and manufactured separately in a factory with accurate dimensions. It can be easily assembled on site, and by transporting each component to the site and assembling it in sequence,
Installation work for septic tank C is completed.

In addition, since this example has fewer components, it can be easily transported to the site, and the assembly work on site can be easily performed. Since there are few problems, the installation state is accurate, and the septic tank C can be firmly and accurately installed in a predetermined position. Furthermore, the fitting state can be made stronger by applying an adhesive to the fitting portion of each member (7).

Note that the longitudinal dimensions of the lower slab plates 1, 2 and the upper slab plates 5.6 can be changed as appropriate R1, and various shapes may be formed in accordance with the longitudinal dimensions of the septic tank C to be installed. It is also possible to connect several sheets in the longitudinal direction and install them on site. Further, the number of lower mounting plates 3 and upper mounting plates 4 arranged can be increased or decreased depending on the length of the septic tank C, etc.

In addition, although this example shows an example of installing a septic tank CL:r)R, similar factory-produced structural members can be used not only for septic tank C but also for other underground objects (for example, underground tanks). The burial work can be completed within 24 hours.

(Effects of the Invention) The installation structure of a septic tank, etc. of the present invention includes a lower slab laid on the bottom side of the constructed burial trench, and a receiver that is erected on the lower slab and formed in an upwardly opening shape.
