Description

Combined Rainwater Storage Tank {Rainwater Storage Tank}

The present invention relates to a rainwater storage tank installed in the basement, and more particularly, by using a cast iron panel in the lower portion of the storage tank to secure the storage space by stacking plastic blocks to secure the movement passage of the worker for maintenance deposition on the bottom of the reservoir The invention relates to a mixed rainwater reservoir capable of carrying out maintenance work, such as cleaning up pollutants from time to time.

In general, as urbanization progresses and drainage develops, rainwater flows into rivers at high speeds, causing frequent flooding, resulting in a lack of rainwater seeping into the ground, resulting in groundwater depletion. have.

In order to prevent this phenomenon, by securing a storage space to store a considerable amount of rainwater in the ground, it controls the speed and quantity of water flowing into the stream by confining rainwater during rainy season, reducing the flooding phenomenon of the river and infiltrating the stored rainwater into the ground. Efforts are being made to prevent groundwater depletion.

According to the prior art Patent No. 10-0782992, four square pillars are provided at the corners of the bottom plate and the top plate, respectively, and are stacked upright to form a concrete block having four open surfaces, and bind each other to the underground rainwater There is what constituted a storage tank.

The prior art neutralizes the cement's toxicity by adding silicate mineral powder as admixture as a mixed material when the storage tank is manufactured to solve the toxicity caused by the toxicity of concrete and the negative ion effect released in large quantities. It provides a low-toxic concrete rainwater storage tank that can prevent pollution of rivers, public waters, or oceans due to the toxic emissions of and prevent corrosion of rebar due to bleaching.

However, not only the toxicity of concrete is not completely removed, but the rainwater stored in the storage tanks stays for a long time, so the concentration of toxic substances eluted from the concrete increases, so if it is penetrated underground or discharged into the river, groundwater pollution and river pollution There is a problem that does not overcome the harmfulness of concrete because it causes.

In addition, after the storage tank is introduced into the storage tank containing various contaminants, the contaminants are deposited and accumulated during the storage process.

Eventually, the water in the reservoir caused by the sediment is not only contaminated but also has a problem that the storage capacity is reduced because the storage space is reduced. In order to improve this, the cleaning work to remove the sediment regularly should be done from time to time. Since the concrete block is small, it is impossible for the worker to enter the storage tank. Therefore, the maintenance work such as cleaning is not designed at all.

In addition, Patent Registration No. 10-0813995 discloses a storage tank structure using a cast iron panel. The storage facility using cast iron panels has the advantage that the cast iron itself has a high strength, so it can be installed without restriction regardless of the depth, load, and water pressure of the storage tank. Although there is an advantage that can be maintained periodically, such as it can be carried out periodically, the cost of facility costs increases due to the high price of cast iron, a raw material, which impedes obstacles in the practical adoption.

In addition, according to the Japanese company "Ogawa Electric Co., Ltd.", a storage block having a support column having a predetermined height is formed on the center or both sides of the rectangular plate body made of plastic material, which is installed on the destroyed reservoir installation surface and supported thereon. The structure is constructed by laminating a repair layer in a structure in which pillars are occluded up and down, and covering the upper portion thereof to complete the structure.

The storage tank has the advantage of securing a solid rainwater storage space at a low cost because the raw material plastic price is low. However, due to the limited strength of plastics and the technical limitations of injection molding, the plastic blocks are manufactured only in small size, so the space between the plastic blocks constituting the storage tank is narrow. If deposits accumulate on the bottom of the reservoir, there is a problem that there is no way to clean them.
