Abstract

PURPOSE:To cut down the number of days required for work and prevent the leakage of hazardous substances in an underground tank and the penetration of underground water as well. CONSTITUTION:Cobble stones 2 are installed to an installation hole 1 while sub-slab concrete 3 is cast. A prefabricated frame-shaped skeleton 4 is set up on the sub-slab concrete 3. The skeleton 4 is installed in such a way that reinforcing bars 5 are exposed crosswise near the bottom of the skeleton 4 while an installation base 6 is formed in one piece with the skeleton. An underground tank 14 is fastened and fixed with the installation base 6 with a fixing band 15 as well. Then, ready-mixed concrete is cast up to the top (line A to A) of the skeleton 4 so that the underground tank 14 may be covered with concrete. At the same time, a foundation slab is formed in one piece with reinforcing bars 5 as a base in the lower part of the underground tank 14. After the cure period of concrete has elapsed, sand 20 is spread over the concrete of the skeleton 4 and an upper base 21 is installed to the skeleton 4. Earth and sand are cast into the installation hole as a final practice and back-filled up to the top (line B to B) of the upper base 21.

As described above, according to the installation method of this embodiment, since the skeleton 4 and the upper board 21 are manufactured in advance in the factory and brought into the installation site, it is necessary to form them by on-site construction. Therefore, the underground tank 14 can be installed easily and in a short period of time. Moreover, the quality of each component can be maintained at a constant high level. Furthermore, since the skeleton 4 is formed in the shape of a frame to serve also as a support for installing the upper board, and the installation base 6 of the underground tank 14 is integrally molded, temporary frame construction for concrete pouring on site is unnecessary. , No need for construction by skilled workers.

In addition, since the underground tank 14 can be completely surrounded by integral molding by continuous casting of concrete, even if a dangerous substance leaks from the underground tank 14, it is possible to prevent it from entering the soil. In addition, when concrete is poured into the skeleton 4, the base slab is integrally formed based on the reinforcing bars 5 laid near the bottom surface of the skeleton 4. Therefore,
Unlike the conventional installation method in which the concrete that surrounds the underground tank 14 and the foundation slab are configured as separate bodies,
Corrosion of the underground tank 14 due to intrusion of groundwater from the boundary portion of those concretes is not caused.

Further, since the skeleton body 4 is shaped like a frame, and the base slab at the bottom is shaped after the skeleton is installed,
For example, the weight of the body 4 can be reduced as compared with the case where the body 4 is formed into a box shape and the base slab is integrated in advance, and the work load can be reduced and safety can be secured. further,
By pouring concrete into the skeleton 4, the skeleton 4 and the concrete inside the skeleton 4 can be made into an integrated structure, and the load from above (including the load of the upper plate 21) is supported as a whole, The strength of the object can be further increased.
