Study on a Kind of Eco-concrete Retaining Wall's Block with Water Purification Function

Considering the environmental protection requirements for retaining wall and slope protection in Civil engineering and construction of water conservancy, a new type of retaining wall materials and structures with functions of slop reinforcement, slope greening and water purification was studied. In this paper, it designed a kind of Eco-concrete retaining wall's block which has functions of slope vegetation planting and water purification, and studied functions of water purification of this kind of Eco-concrete retaining wall's block through the water quality purification experiment. It shows that, the maximal disposable removal rates of CoDcr, TN and TP are respectively 87%, 70% and 90%, which means that functions of water purification of this kind of Eco-concrete retaining wall's block are very good.
