Embodiment 1
[0014] Because the spillway of this embodiment is in the plain river course, the artificial roughening of the bottom of the spillway near the downstream two-thirds is to directly use cement to make protrusions of different shapes on the bottom of the groove as roughening objects, according to the Closer to the downstream channel, the larger the roughness is required to be built.
Embodiment 2
[0016] Because the spillway of this embodiment is also in the plain river course, the artificial roughening of the bottom of the spillway in the downstream two-thirds part uses prefabricated cement blocks of different shapes made in advance or on the spot as roughening objects, according to the closer The downstream channel, the greater the roughness, is required to be constructed.
Embodiment 3
[0018] Because the spillway of this embodiment is located in a mountainous river, the bottom of the spillway near two-thirds of the downstream is artificially roughened using pebbles in the river as roughening objects. The closer to the downstream river, the greater the roughness. Ask to build.
