In addition, the existing ecological bank protection building blocks are mostly of a single-cavity structure (with holes on the outer walls of the building blocks), so that the structural strength of the building blocks is guaranteed, the single-cavity ecological bank protection building blocks are constructed in a tiled mode, and therefore the river bank side slope is slow, and the occupied land is large. In addition, in the construction process of the single-cavity ecological bank protection building block, in order to increase structural integrity, the corner of the building block is set to be of a mortise and tenon structure, and accordingly the construction difficulty is increased.
In addition, ecological bank protection engineering is mostly river channel reconstruction engineering in cities, and the small-sized pond is basically designed for natural slopes due to inconvenient mechanical construction and small reconstruction engineering investment. However, natural side slopes are easily washed by water flow, so that water and soil loss is caused; meanwhile, the natural side slope gradient is generally slow, so that the estuary is wider, and the land occupation problem can be encountered in the process of reconstruction of the river and pond. The arrangement of the ecological bank protection engineering can properly improve the slope gradient, reduce the width of the estuary, reduce the occupation of the land and realize the ecological reconstruction of the pond.
