With dedicated operation port | High tensile grating weir plate with pocket
Recommended for agricultural management pits! A drainage pit that frees you from the heavy lifting of grates.
Operation of the weir board necessary for water distribution and flow adjustment to the rice fields. Isn't it difficult to lift the large manhole cover? As the manhole gets larger, the cover becomes heavier, and there is also the risk of falling from the wide opening. Many of the weir boards used in collection manholes are installed inside the manhole with a gate that has a vertical groove called "kakuro" at the connection point with the roadside ditch or agricultural waterway. 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 distribution and flow changes to the rice fields without having to open the large manhole cover.
