The method of stacking fishway blocks in an oval shape allows for a significant reduction in the site area.
■The method of stacking fishway blocks in an oval shape significantly reduces the site area. ■The product shapes used for the curved and straight sections are standardized, which enhances workability. ■By creating a track shape with straight sections between the semicircular parts, the flow conditions in the pool are adjusted to facilitate fish ascending. ■The slope of the fishway has the semicircular return section at level and the ascending straight section at a gentle slope of 1/10, improving the ascent efficiency compared to a circular shape. ■The partition wall adopts an ice harbor method that accommodates small fish species. ■By rounding the shape of the overflow section of the partition wall, it creates a submerged flow that is easier for fish to ascend. ■Overflowing at the fishway outlet section allows for adjustment of the fishway flow rate. ■Light windows are installed to ensure adequate illumination.
You can freely choose the slope! This birdfish nest block can be used not only as a fish nest but also as a fishway.
This is a fish nest block that has a shape resembling a cut top slab and upper side walls of a box culvert. It creates natural depressions suitable for the ecological environment of aquatic life. The block has good water and light permeability, making it suitable for the growth environment of aquatic plants, algae, and plankton. It allows for relatively easy inflow and outflow of sediment, which helps prevent functional degradation. By laying stones on the bottom slab, a natural environment is formed, making it suitable for the activities and spawning behaviors of aquatic life. Its stepped structure helps prevent water accidents caused by falls or slips, and it provides a platform for cleaning operations within rivers. Patterns can be added to the front wall, harmonizing with the landscape. The slope can be freely selected (1: 0.5 to 2.0). The stagnant water areas are conducive to the growth of reeds and other vegetation, creating an environment for bird nesting. It is easy to install and does not require specialized skills such as those needed for block work. It can be used not only as a fish nest but also as a fishway.
L-shaped parapet blocks that enable elevation by being installed on top of levees and tidal barriers.
■Early flood prevention measures are possible. ■The impact on the surrounding environment can be minimized. ■It accommodates product heights of 1.1 to 1.5 meters. ■No need for cast-in-place concrete. ■Easy installation, shortened construction period, and labor-saving on-site work can be achieved. ■A shape is adopted that sets the backfill height low to minimize the impact on existing structures. ■It has a strong integrity with three reinforced fittings. ■Waterproofing between products is ensured by sealing materials.
