METHOD FOR CONSTRUCTING SCOUR PROTECTION OF BRIDGE AND STABILIZATION OF STREAM BED USING BLOCK MAT

摘要

This method be used for construct scour protection bridge and stable river bed using concrete block armour layer according to the present invention pass through construct several concrete block armour layer structures be interlocked by cell block, riverbed ground peripheral part submerged structure of the single layer or multilayer that are laid with the concrete block armour layer structure has a better understanding. Through the invention, the resistance decline stream that can be improved is in upper and lower region bridge pier, to prevent from local riverbed wash away be by flowing the flexibility due to concrete block armour layer, and stablize ground riverbed due to the space between cell block full of gravelly sand in multiple duplicate flood currents and common stream, then pad becomes secured.
