The integral rectangular structure of hooked stone cage net adopts the latest environmental protection technology, which is mainly used as the slope protection structure of river course, bank slope and roadbed slope. It prevents river banks from being eroded by currents and wind waves. In the construction process, the cage filled with stone, constitutes a flexible structure, strong permeability of the whole material, is conducive to promoting the rapid growth of natural plants.

In river regulation engineering, the traditional river revetment or slope protection generally uses masonry or concrete, three-sided light, impervious, can not meet the needs of natural ecological river regulation, and the hooked stone cage net has strong anti-scouring ability, strong permeability, and is a porous structure that is easy for living organisms, so it is often used in the construction of multi-natural ecological river. In the middle.
