Modular geogrid retaining wall with construction waste as filler and construction method

The invention provides a modular geogrid retaining wall with construction waste as filler and a construction method, relates to the technical field of construction waste, and effectively utilizes the advantages of high strength, good stability, good water permeability, frost heaving prevention and the like of concrete blocks, broken tiles, broken gravels and the like in the construction waste. The novel module type geogrid retaining wall with the geogrid as the filler has the advantages of being low in cost, wide in applicability, good in water permeability, environmentally friendly and the like. The retaining wall comprises one layer of module units, or more than two layers of module units are arranged in the height direction, and the module units on the two adjacent sides are stacked in a staggered mode. The two adjacent module units on the same layer are connected; every two adjacent module units in the height direction are connected. Each module unit comprises a steel wire mesh structure and construction
