Selection of ecological revetment in waterscape engineering?

The following is the selection of ecological revetment in waterscape project brought by Zhong Da Consulting for your reference.

(1) Natural prototype revetment For the river reach with gentle slope or large hinterland, it may be considered to maintain the natural state and cooperate with plant planting to stabilize the river bank. Such as planting willow, poplar, poplar, beating tree, reed, pappus and other plants with water-loving characteristics, whose developed roots grow and stretch, and stabilize the embankment. In addition, their branches and leaves are flexible and conform to the current, which increases the ability of flood control and dike protection. The traditional river management method in China is a summary of this aspect. (2) For natural revetment with steep slope or serious erosion, in addition to planting vegetation, natural stone and wood are also used to protect the bottom to enhance the flood resistance of the dike. For example, gabions, wooden stakes or mortar stones (without fish nests) are used to protect the bottom of the slope, and an earth embankment with a certain slope is built on it, and vegetation is planted on the slope. Implement the combination of arbor, irrigation and grass, and strengthen dikes and revetments). (3) When the gravity retaining wall must be built in the river section with high flood control requirements and small hinterland, the stepped artificial natural revetment should be layered step by step. On the basis of natural dike protection, reinforced concrete and other materials are used to ensure greater flood resistance. For example, a trapezoidal box frame is made of reinforced concrete columns or water-resistant logs, and big stones are placed, or concrete pipes with different diameters are inserted to form a deep fish nest, and then willow branches and poplar branches are buried in the box frame. Adjacent to the water surface, aquatic plants such as reeds and calamus are planted, so that lush green vegetation can grow in the cracks.
