A multi-piece precast concrete structure that assembles and is installed in an irrigation canal perpendicular to the flow of water. This structure is designed to control water flow in the canal.
Precon’s Check Structure is a multi piece (typically using 9-13 pieces) precast concrete structure that assembles together in the shape of an ‘H’ and is installed in an irrigation canal perpendicular to the flow of water. The shape of the structure creates a double water cutoff, ensuring that water cannot get around or under the structure, helping prevent bank erosion.
The Check Structure is engineered and designed to USBR standards and is a reliable solution for water flow control in a water conveyance system. The Check Structure allows the designer to control water levels and water velocity, which works well in conjunction with Precon’s Inlet/Turnout as a way to obtain necessary water levels for water delivery.
The structure is designed for canal's with flows as large as 3.5 cubic metres per second. We take into account the width of the canal at the top and bottom, the flow of water, and the type of gate when designing. The structure can accommodate Overshot, Stop Log Systems and several other popular gate systems. The Check Structure can also be used to measure the flow of the water.
1. Level control in the storage, deliver and drainage of water systems
2. Weir Structure
Precon’s Check Structures are produced in many different sizes to accommodate the specific application. Size depends on flow. Precon can design structures for flows between 1.0 cubic metres per second to 3.5 cubic metres per second.
There are many options that can be added to or cast into many Precon products
