A kind of interlocking prefabricated concrete block paving system that can be installed manually and is suitable for the control of soil water erosion under medium and small flow conditions. Chain interlocked retaining bricks with a unique interlocking design, each block and the surrounding six blocks produce super strong linkage, the surface of the store has a zero stability under the effect of water flow; high open porosity permeated flexible structure paving can reduce the flow rate and reduce fluid Pressure and increase drainage capacity.
