#CMT# #/CMT# The method involves digging into a railway embankment, laying a prefabricated foundation plinth (1) with two lower holes (4, 4a) through an inner hollow space (3a), laying and cementing reinforcement rods (5, 5a) with two lower anchoring micropiles through the inner hollow space, laying an upper steel support (2) in the inner hollow space, cementing the adjacent empty space and installing the sound-absorbent panel (6) on the support. #CMT# : #/CMT# The foundation plinth has a width of 42-84cm, preferably 60cm, and a length of 63-126cm, preferably 90cm. #CMT#USE : #/CMT# For installing the supports of sound-absorbent panels for railway lines. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side sectional view of the foundations, supports and panel.
