Seismic-resistant water storage tanks [40m³, 60m³ to 100m³] Our products are certified products that comply with the secondary product fire water tank (40m³) and secondary product seismic-resistant water storage tanks [40m³ type, 60m³ type, and 100m³ type] conducted by the "Japan Fire Equipment Safety Center," designated by the Fire and Disaster Management Agency as a subsidized project. The products are available in Type I and II standalone types and Type I and II shared types. Type I is installed underground in locations such as parks and residential areas where vehicles are unlikely to enter, subjected to a uniformly distributed load of 10 kN/m², while Type II is installed underground in other locations, subjected to a total weight of 200 kN from vehicle loads.

With the development of residential land and other projects, it is necessary to install retention basins to prevent the decrease in safety levels in downstream areas due to increased flood flow in rivers. The "Open-Type Retention Basin II" is a product that serves as a storage facility to mitigate road flooding and residential inundation caused by urbanization in river basins. It is easy to maintain after construction. Additionally, since the bottom slab is constructed on-site, it is possible to create pit areas and drainage slopes. 【Design Conditions】 ■ Superimposed Load: Q=10kN/m2 ■ Unit Weight of Soil: W=18kN/m3 ■ Internal Friction Angle of Soil: Φ=30° ■ Soil Pressure Calculation: Trial Wedge Method ■ External Water Level: Hw = Total Height / 2 *For more details, please download the PDF or feel free to contact us.

The "play water area" is a facility for rainwater runoff control installed underground, while the surface can be used for various purposes such as schoolyards, parking lots, and parks in a multi-dimensional way. It allows for a shortened construction period and is economical. It can also be used for domestic water, fire-fighting water, and as a facility for storing rainwater or rainwater infiltration. Additionally, it is a structure that has seismic resistance against earthquakes equivalent to levels 1 and 2, with an internal height of 1.5m to 4.0m for box types and 1.5m to 7.0m for stand types. 【Features】 ■ Effective use of land ■ Shortened construction period and economical ■ Usable for domestic water, fire-fighting water, and as a facility for storing rainwater or rainwater infiltration ■ Internal height - Box type: 1.5m to 4.0m - Stand type: 1.5m to 7.0m *For more details, please refer to the PDF document or feel free to contact us.

The "open-type retention basin" is a storage facility that can accommodate an internal height of 3 to 7 meters. Being open-type, it allows for easy maintenance and management after construction. Additionally, it can be constructed to fit the shape of the site, and a fence can be installed on the top edge of the product. 【Features】 ■ Easy maintenance and management after construction due to its open type ■ Shorter construction period, making it economical ■ Can be constructed to fit the shape of the site ■ Accommodates internal heights of 3 to 7 meters *For more details, please refer to the PDF document or feel free to contact us.

Due to land development and other factors, it is necessary to install retention basins to prevent the safety of downstream areas from being compromised by increased flood flow in rivers. The "Open-Type Retention Basin II" is a product that serves as a storage facility to mitigate road flooding and residential inundation caused by urbanization in river basins. Being an open type, it is easier to maintain compared to underground types after construction. Additionally, the bottom slab can be constructed on-site, allowing for the creation of pit areas and drainage slopes. 【Features】 ■ The bottom slab is constructed on-site ■ Pit areas and drainage slopes can be created ■ Water-stopping structures can utilize either the "Sealing Method" or the "TSKJ Method" ■ There are holes for fence installation at the top of the product, allowing for fence erection *For more details, please refer to the PDF materials or feel free to contact us.

The "Mini Gate" is an underground rainwater storage facility designed for multi-purpose use of the land above, such as parks, schoolyards, and parking lots. Due to its large internal space, maintenance tasks such as inspections and cleaning can be performed inside the storage tank. While a pump drainage system is possible, it can be made economical by standardizing the internal height to allow for a natural flow system that does not require mechanical equipment like pumps. 【Features】 ■ Maintenance tasks such as inspections and cleaning can be performed inside the storage tank. ■ Flexible design can be tailored to the site. ■ Earthquake resistance against seismic motions equivalent to levels 1 and 2. ■ Installation costs are reduced and economical due to a product weight of less than 5 tons. ■ The use of inverted concrete allows for the establishment of any desired slope. *For more details, please refer to the PDF document or feel free to contact us.

"Riserain Stadium II" is a storage facility that consists of a rainwater retention tank or infiltration tank, formed by stacking plastic components and wrapping them with a waterproof sheet or a permeable sheet, which includes multiple tunnel structures. The main components have handles for easy manual installation, and the side panel components can be attached with a single touch. Utilizing the tunnel structure inside the tank, cleaning operations can be performed using maintenance tools (self-propelled cameras, vacuum hoses). Additionally, since this component can be delivered to the site without using pallets, there is no need for pallet collection or industrial waste disposal after construction. 【Features】 ■ The main components have handles for easy manual installation. ■ The side panel components can be attached with a single touch. ■ Cleaning operations can be performed using maintenance tools (self-propelled cameras, vacuum hoses). ■ Some materials used are recycled materials. ■ Complies with the Ministry of the Environment Notification No. 46 "Environmental Standards Regarding Soil Contamination" and RoHS standards. *For more details, please refer to the PDF document or feel free to contact us.
