Renovation of the existing underground drainage ditch to a bolt-fixed type by simply replacing the cover.
The High-Tension Hard Rock System Grating is a grating that can be easily installed on existing variable ditches or slim-type drop-in ditches, preventing the grating cover from bouncing or wobbling.
Theft prevention hardware for raised grating | Prevents theft by fitting under concrete covers.
Almost all of the grates that are stolen nationwide lack fixed or restraint features. The absence of grates can lead to unexpected accidents such as vehicle rollovers, wheel detachment, and children falling. For raised grates suitable for road ditches, variable ditches, and underground ditches, we have solutions that cover about 90% with two types of fittings.
Leak repair and weed control sheet | Made of rubberized asphalt for great effectiveness
Weeds that grow in the slightest gaps of roads, water leaks caused by cracks and shifts in drainage... The effects of weeding and repair tape are not very effective. In such cases, we introduce the "Multi Maintenance Sheet," which has a proven track record of over 400 km nationwide, including the Ministry of Land, Infrastructure, Transport and Tourism and the Agricultural Policy Bureau, for weed control and leak repair.
Recommended for agricultural management pits! A drainage pit that frees you from the hassle of opening and closing heavy grates.
Operation of the weir board necessary for water division and flow adjustment to the rice fields. Isn't it difficult to lift the large manhole cover? As the manhole increases in size, the cover becomes heavier, and there is also a risk of falling from the wide opening. Many of the weir boards used in collection manholes are installed by constructing a gate with a vertical groove called "kakuro" at the connection point with roadside ditches or agricultural waterways, which is inserted into the inside of the manhole. Therefore, when operating the weir board, it is necessary to open and close the manhole cover grating. For this reason, we recommend the "high-tension grating weir board pocket" that allows for water division and flow changes to the rice fields without opening the large manhole cover.
Shoveling snow is tough. At least, I want to make the lid lighter.
As the population ages, a budget was allocated to introduce spring-operated snowmelt gutter grates. Residents were thrilled with the light opening and closing during snow removal! However, a few years later, the device deteriorated, resulting in the same heavy standard grates as before... If that was the case, it would have been better to use standard snowmelt gutters from the beginning and allocate the funds to other maintenance costs. Therefore, we now have lighter snowmelt gutter grates without the weight reduction device.
