Summary: RCCD asks oneself that since generation, develops very fast, but its prevention of seepage has been the focus that people have paid close attention to all the time . The prevention of seepage of RCCD includes two respects mainly: The prevention of seepage which rolls the noumenonn of concrete (RCC) combines the prevention of seepage of Taxi with layer. The prevention of seepage of its noumenonn can meet the request of the water conservancy project building, but its aspect is relatively bad in prevention of seepage, must deal with the aspect .
