Hardening riverway ecological protection band alternately used in rainy season and dry season
The invention discloses a hardening riverway ecological protection band alternately used in the rainy season and the dry season. Cylindrical steel rails of the protection band are fixed to river bank sides. Gaps are formed in one sides of the cylindrical steel rails, and second chain wheels are arranged at the gradient reducing positions. Chains penetrate hollow parts in the cylindrical steel rails and are wound around first chain wheels at the top ends of the cylindrical steel rails and second chain wheels at the lower portions of the cylindrical steel rails. Round rods penetrate trapezoid grooves and pass the gaps of the cylindrical steel rails to be fixed to the chains. Matched gaps between the round rods and through holes in the two sides of the trapezoid grooves are plugged through plug gaskets. The sides, facing the river, of the trapezoid grooves are provided with water outlet holes, and the upper edges of the sides, making contact with the river banks, of the trapezoid grooves are provided with arc edges. Lower layers in the trapezoid grooves are filled with a fine filter material, upper layers in the trapezoid grooves are filled with a coarse filter material, and plants are planted. The hardening riverway ecological protection band has the technical beneficial effects that in the rain season, the step type arrangement of the trapezoid grooves along the river banks is adjusted, and rainfall runoff is processed in a multi-level manner; and in the dry season, the trapezoid grooves can be orderly formed in the two sides of the riverway, water can be purified, the plants can be cared, and the landscape effect of greening and beautifying the riverway is achieved.
