With dedicated operation port | High tensile grating with pocket for weir plate
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.
