The "BZ base-mounted pipe" is a high-strength external pressure pipe that does not require a concrete foundation due to its base-mounted shape at the bottom. Thanks to the high-performance rubber joint (BZ gasket), it ensures the water tightness of 0.10 MPa required at the joints as an external pressure pipe. Additionally, due to the bi-con manufacturing method, it has high durability against neutralization, abrasion resistance, and chemical resistance, contributing to the longevity of structures. 【Features】 ■ Excellent workability, seismic resistance, and environmental performance ■ Base-mounted shape eliminates the need for a concrete foundation ■ Built-in high-performance rubber joint ■ Quick and reliable lifting ■ Structure that is resistant to eccentricity *For more details, please refer to the PDF document or feel free to contact us.

Introducing the Hume Scepter, a product designed for surface drainage measures. The Hume Scepter is a product that incorporates an invert device within a prefabricated manhole for sewage systems. It can separate and capture pollutants such as oils contained in rainwater drainage. The invert device collects rainwater drainage into a retention tank and utilizes differences in specific gravity for separation. It helps reduce non-point source pollution flowing into closed water bodies such as lakes and rivers, contributing to water quality improvement. The structure is in the shape of a prefabricated sewage manhole, and installation is very simple, as it can be completed by just stacking the components. ◎ You can view detailed specifications and more by downloading the catalog. If you are interested, please download and check the catalog.

The most dangerous situation regarding slip and fall accidents is when there are items with varying slip resistance scattered around. (Typical manhole covers have a lower slip resistance compared to the surrounding pavement.) [Effects of Rosingrip] ○ Slip prevention effect Glass beads are embedded in the sheet and thermally fused to the surface of the manhole cover, providing slip resistance comparable to the surrounding pavement. ○ Environmentally friendly! The main component of the binder is natural materials such as pine resin. It contains no harmful substances. ○ Easy to install! The anti-slip installation is completed in about 50 minutes. ○ Specifications Color: Black Dimensions (mm): 500×1100 ★ Available for purchase online.

Conventional methods use sandbags, which are not sufficient for water stopping, leading to the need for the installation and cost of submersible pumps. The Exstopper is a product that enhances the water-stopping ability and workability that were problematic during water replacement in conventional methods. It fixes the water-stopping plate inside the pipe and drains using a temporary pipe.

1. High separation capability In the storage tank, the flow rate of the collected water decreases (to about 1/100), allowing very difficult-to-separate fine particles (SS) to settle in a still water state. Oil components are captured by the invert device. 2. Pinpoint treatment method By focusing on treating relatively high concentrations of pollutants during low rainfall (initial rainfall), the treatment area per unit increases, allowing for fewer installations. 3. Easy construction The structure is a prefabricated manhole shape for sewer systems, so construction is completed by stacking on-site. 4. Space-saving Each function is arranged vertically, making it compact and requiring less installation space. Being underground, only the manhole cover appears above ground. 5. Easy maintenance Due to its structure that does not use power or consumables like filter materials, maintenance only involves cleaning the inside of the storage tank.

Fallen leaves in green belts and parks gather in grates due to rain and wind. The leaves that accumulate in the grates pile up around the grates, obstructing drainage. In the case of Water Leaf, the leaves are pushed out by the force of the water. 【In the case of conventional products】 Leaves get caught at the edges of the grates and accumulate there. The leaves cover the area around the grates, allowing water to pass through the grates. 【In the case of Water Leaf】 Leaves are pushed towards the center of the grate by water flowing down the slope. Since the guide slope section is always open, it allows for sufficient drainage of rainwater.

• Grating

On roads with a steep longitudinal gradient, a phenomenon occurs where water collected in the grating overflows and passes over the grating. The amount of water that cannot be collected by the grating increases, leading to a situation where a large volume of rainwater is not drained. With the Water Wolf, this overflow phenomenon is eliminated. [NETIS Registration Number KK-060045]

【Shoulder Clarity】 【Bicycle Path, Bicycle Lane Compatibility】 The twin drainage ditches are equipped with continuous water channels and drainage holes just below the surface of permeable pavement, providing high drainage capacity by draining water within the permeable pavement layer downwards. Additionally, the surface of the ditches at the edge of the roadway is not exposed, and the pavement surface continues uniformly up to the boundary blocks of the pedestrian and vehicle areas.
