River retaining wall structure with buoyancy base and its construction method

Abstract

This invention relates to a river retaining wall structure with a buoyancy foot, comprising multiple foundation stone cages, a buoyancy foot, and multiple consolidation stone cages. The foundation stone cages are stacked on the riverbed and upwards along the riverbank slope. The buoyancy foot is located between the foundation stone cages and is integrated with adjacent foundation stone cages. Each buoyancy foot has a load-bearing section, two supporting sections, and a wall section. The supporting sections are located at the bottom ends of the load-bearing section, and the wall section is located on the load-bearing section. The consolidation stone cages are stacked in a stepped manner on the load-bearing section. The foundation stone cages and consolidation stone cages effectively absorb the impact of river water and driftwood and soil in the river, preventing them from being eroded by river water, thus enhancing the overall strength of the river retaining wall structure. Furthermore, underground water and surface runoff can pass through the foundation stone cages without water accumulation, thereby maintaining the strength of the river retaining wall structure. This invention also provides a method for constructing the river retaining wall structure.
