Method for manufacturing noise control wall element, involves inserting of absorption layer in formwork, on these layers reinforced, settled base layer is applied in liquid or pasty form

摘要

The method involves inserting of an absorption layer (2) in a formwork (1), on these layers the reinforced, settled base layer (3) is applied in liquid or pasty form and also with another absorption layer (4). The three layers are pressed together, until the entire wall element has reached a pre-determined thickness.
