Erosion protector for soil and sand in sea bed, etc.
Abstract
Abstract PURPOSE: To prevent the breakdown of pier due to the excavation of soil and sand at the sea bed by the flow of the sea water by attaching a mat on which a large number of fibers are flocked upwardly to the surrounding of the piers, etc., of a bridge or structure set at the sea bed. CONSTITUTION: The foundation 2 of the pier 1 of a bridge or structure set at the sea bed or river bottom, etc., is in danger of falling due to erosion 92 of soil and sand by the flow 93 of the sea water or river water. Thus, a mat 14 as an erosion protector 13 of a synthetic resin, etc., having a high durability to the sea water, etc., on which a large number of fibers are flocked, is placed on the sea bed surrounding the pier 1. By the fibers 15, the flow of water is retarded and the soil and sand are deposited in and around the pier 1 to form a reinforced soil combined with the fibers. Thus, the falling of the pier 1 by excavation and erosion of soil and sand around the pier 1 by the flow of water can be avoided. COPYRIGHT: (C)1982,JPO&Japio
