SEAMLESS CLOSE CONNECTION TYPE PLASTIC RESIN BULKHEAD STRIP

摘要

PROBLEM TO BE SOLVED: To provide a seamless close connection type improved plastic resin bulkhead strip.SOLUTION: At least one sealing projecting rib or two sealing projecting ribs are formed on one or both of a tang edge outer surface and an edge groove inner surface of each bulkhead strip. When the bulkhead strips are mutually connected, the sealing projecting ribs can be used to certainly fill a gap between the tang edge outer surface and the edge groove inner surface, thereby making it possible to avoid flooding and prevent bed load loss and land subsidence.
