Conventionally, after the buried groove H is excavated at the installation site, the concrete base 52 is poured into the bottom surface of the concrete base 52 together with the foundation part 51. When the upper surface of the septic tank C is used as a parking lot, the slab layer is formed above the septic tank C, and the reinforcing column for supporting the slab layer is embedded in the buried groove H. Since it was constructed by the method of pouring concrete into it, concrete work was required at the site, there was a lot of pre-work to install the septic tank C, a considerable construction period was required, and the concrete base 52 and It is necessary to perform strict quality control of the concrete to secure sufficient strength of concrete such as reinforcement columns, and a great deal of labor is required for civil engineering work and quality control. There is a problem that it requires.

(Means for Solving Problems) The present invention has been devised in view of the above-mentioned conventional problems, and does not provide an installation structure capable of completing installation work simply and quickly when installing a septic tank or the like. For the purpose, the gist thereof is a structure in which an underground buried object such as a septic tank is installed on a slab plate formed in a flat plate shape by a precast concrete plate (PC plate) forming a foundation surface, and the lower part of the underground buried object. Is provided with an appropriate number of mounts, and the slab plate is formed with grout holes for level adjustment at appropriate intervals along the longitudinal direction thereof.

(Operation) A slab board is laid on the bottom of the buried groove constructed on the site, mortar etc. is injected into the grout hole of the slab board to adjust the level of the slab board, and a septic tank, etc. is placed on the top of the slab board via a stand. Can be installed and the installation work can be completed, there is no need to perform concrete pouring at the site as in the past, and the septic tank and the like can be installed easily and in a short time.

When using the upper surface of the septic tank as a parking lot, the upper slab is made of reinforced concrete or the like above the septic tank, but reinforcement columns to support the upper slab are also manufactured by factory production. If such members are used, a septic tank or the like can be installed by assembling them on site.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 to 5, the septic tank C is formed of a material such as FRP into a cylindrical shape, and a manhole Ca having a projecting upper opening is integrally formed on the upper surface thereof. Inside the septic tank C, a sedimentation separation tank, a contact aeration tank, a sedimentation tank, and the like capable of purifying human waste water and domestic waste water are incorporated. This septic tank C is molded at the factory, and when installing the septic tank C in a buried state on the site, in this example, the slab plate 1 and the pedestals 2 and 3 that are similarly manufactured at the factory are used. To do.

That is, the slab plate 1 is a PC as shown in FIG.
It is formed into a plate shape by a plate (precast concrete plate), and a pair of engaging grooves 1a and 1b having a concave cross section is formed along the longitudinal direction on both sides of the surface side thereof. Notches 1c are formed at appropriate intervals along the longitudinal direction on both side edge portions, and hook rebars 1d project into the notches 1c. Further, concave connecting grooves 1f are formed at appropriate intervals also in the lateral direction of the slab plate 1, and hook reinforcing bars 1d are formed to project in the connecting grooves 1f. By connecting a plurality of the slab plates 1 in the longitudinal direction via hook rebars 1d in the connecting groove 1f, a slab plate having the same size as the septic tank C is formed. The connected state is enlarged and shown in FIG. 3 and FIG. J in the figure
Is a connecting fitting for connecting the opposing hook rebars 1d.

In addition, the slab plate 1 is formed with grout holes 1e at appropriate intervals along the longitudinal direction. If the length of the slab plate in the longitudinal direction is, for example, 9 m, a slab plate of 4 m 1
And 5m slab 1 can be combined, and other 3
If the slab plate 1 formed in each length of m, 4 m, 5 m, etc. is prepared, the slab plate of the required length can be obtained by appropriately combining.

On the other hand, the pedestals 2 and 3 are symmetrically shaped by factory production, and arc surfaces 2b and 3b capable of contacting the lower surface of the septic tank C are formed on the upper surface side of the pedestals 2 and 3, respectively. , 3b are formed integrally with locking projections 2a, 3a below. The engaging protrusion 2a of the gantry 2 is formed in a shape that can be fitted into the engaging groove 1b of the slab plate 1, and the engaging protrusion 3a of the gantry 3 is the engaging groove 1a of the slab plate 1. It is formed into a shape that can be fitted into. The mounts 2 and 3 are factory-produced using, for example, a PC version.

When installing the septic tank C using the slab plate 1 and the pedestals 2 and 3 as shown in FIG. 5, the foundation part 51 is previously constructed on the bottom surface side of the embedding groove H by gravel or the like at the installation site. In that state, the connected slab plate 1 is laid from above and mortar or the like is injected into the grout hole 1e of the slab plate 1 to adjust the level, and the mortar or the like is also placed in the connecting groove 1f of the slab plate 1. The slab plates 1 are injected and joined to each other, and the pedestals 2 and 3 are placed from above the laid slab plate 1 along the longitudinal direction of the slab plate 1 at appropriate intervals and in an appropriate number. At that time, the respective locking projections 2a, 3 of the pedestals 2 and 3
By fitting a into the engaging grooves 1a and 1b of the slab plate 1, the slab plate 1 and the pedestals 2 and 3 are integrated. In that case, it is also possible to firmly fix the both via an adhesive or the like.

In this way, after a suitable number of pedestals 2 and 3 are arranged facing each other on the upper surface side of the slab plate 1, the septic tank C is placed on the arc surfaces 2b and 3b of the pedestals 2 and 3 from above, Stand 2,
It is possible to fix the septic tank C on the surface of the container 3. At that time, since the locking projections 2a and 3a of the pedestals 2 and 3 are fitted into the engaging grooves 1a and 1b of the slab plate 1, the pedestals 2 and 3 are firmly fixed without lateral displacement due to the pressing force from above the septic tank C. Septic tank C
Can support. In this state, the slab plate 1 is further
By hooking a float prevention wire or the like on the hook rebar 1d protruding from the notch portion 1c of the wire, the wire is laid over the upper peripheral surface of the septic tank C, and the end of the wire is tied to the hook rebar 1d on the opposite side. The septic tank C can be fixed more firmly via the via, and the septic tank C can be prevented from floating. After the septic tank C is fixed, the buried groove H is filled, and only the manhole Ca projecting to the upper surface side of the septic tank C is opened to the surface of the ground, and the installation work of the septic tank C can be completed.

As described above, in this example, the septic tank C can be easily installed by simply carrying in the slab plate 1 and the pedestals 2 and 3 that have been modeled by factory production and arranging them at predetermined positions. Therefore, the installation work of the septic tank C can be completed in a short time. Moreover, the slab 1 and the pedestals 2 and 3
Can be molded in a factory under strict quality control, so quality such as strength can be secured satisfactorily. The septic tank C can be firmly installed without the need for management.

In FIG. 6, the width of the buried groove H is increased so that the buried groove H

Also in this example, since the slab plate 1 and the pedestals 2 and 3 are modeled by factory production, the installation is extremely easy. In this example, the anti-floating wire is hung on the hook rebar 1d of the slab plate 1 of each septic tank C, each wire is laid over the upper surface of each septic tank C, and the end of each wire is tied to the hook rebar 1d on the opposite side. Thereby, each septic tank C can be fixed.

Further, FIG. 7 shows an installation structure when the surface of the septic tank C is used for a parking lot or the like.

In this example, the foundation part 51 is formed on the bottom surface side of the buried groove H in advance by gravel or the like at the installation site, and the factory-produced slab plate 1 and the pedestals 2 and 3 are installed on the top surface thereof. The septic tank C is mounted on the column, and a column for reinforcing the upper slab 6 is arranged on the side edge of the septic tank C. That is, a suitable number of support bases 4 and 4 shaped by factory production are arranged at predetermined intervals along the longitudinal direction of the slab plate 1 on both side edges of the slab plate 1 that has been laid. Since the recessed engaging recesses are formed, the reinforcing columns 5 having the engaging protrusions that can be fitted into the engaging recesses are erected on the support bases 4 and fixed by the bolts 7. An upper slab 6 is formed on the upper ends of the reinforcing columns 5 by using reinforced concrete or the like, and the upper slab 6 supports the vehicle weight and the like. Since the reinforcing column 5 and the support base 4 can also be formed by factory production, the installation can be easily performed and the installation work can be completed in a short time.

In FIG. 8, the width of the buried groove H is increased so that the buried groove H
An example in which two septic tanks C are installed side by side inside is shown.

In this example, three reinforcing columns 5 are used in the width direction, and an upper slab 6 is formed above them. The central reinforcement column 5 is also used as the two septic tanks C, C. The upper slab 6 can be adjusted to a suitable size.

In addition, in the said Example, although the case where the septic tank C was installed in the burial groove H was described, the same structural member is not limited to the septic tank C but other underground buried objects (for example, an underground tank etc.). It can be installed easily as well.

(Effects of the Invention) The present invention is a structure in which an underground buried object such as a septic tank is installed on a slab plate formed in a flat plate shape by a precast Ncleet plate (PC plate) forming a foundation surface, In addition to providing a suitable number of pedestals in the lower part of the slab, by forming grout holes for level adjustment at appropriate intervals along the longitudinal direction of the slab plate, the structural member is carried into the site, A slab plate is laid on the bottom of the buried groove constructed on the site, mortar etc. is injected into the grout hole to adjust the level of the slab plate, and a septic tank etc. can be installed on the slab plate via a stand, which is the conventional method on site.
