そのため、貯水量が減少するとともに、必要以上の材料
を要し不経済さを免れない。However, construction using cast-in-place concrete requires reinforcement work, formwork carpentry, or skilled workers such as scaffolding and support work, and shortens the construction period because of concrete curing. There is a problem of difficulty. In particular, since the side wall has a large area and a large amount of formwork is required, on-site construction becomes complicated and a lot of time is spent. On the other hand, with the precast box culvert, the construction period can be shortened compared to the case of casting on site, but since box-shaped box culverts are installed side by side, there is also a wall inside the storage tank. Become.
As a result, the amount of water storage decreases, and more material is needed than necessary, which is uneconomical.

There are some difficulties in terms of safety. This kind of difficulty also applies to the one constructed by the PC concrete wall. As a measure for solving the above-mentioned inconvenience, for example, only the bottom plate is made of cast-in-place concrete, and a side wall made of precast concrete block is erected on the bottom plate to construct a storage tank, and a floor member covering the upper surface thereof. It is conceivable to support the columns with columns or beams.

があった。However, when a wall member made of a precast concrete block is placed on a bottom plate made of cast-in-place concrete to form a side wall or the like, it is possible to secure the joint strength and sealing property between the bottom plate and the side wall. There was a problem that it was difficult.

ができることとなった。Since at least the side plates of the rainwater storage tank according to this prior application are made of precast concrete blocks, large-scale formwork work is not required, and it depends on skilled workers such as reinforcing bars, formwork carpenters, or scaffolding and support work. It has become possible to significantly reduce the degree and prevent the construction from becoming complicated, and also shorten the construction period. Moreover, if the connection between the side wall and the bottom plate is as described above, it becomes possible to secure both high mechanical strength and sealing performance, and the wall member is provided with a concave and convex engaging portion that allows lateral movement on the bottom plate. Since it is mounted via the wall member, it is possible to comfortably tighten the wall members forming the side wall in the direction toward each other by the connecting member.
It has become possible to sufficiently secure the sealing property of the joint portion between the wall members.
