Reinforced concrete noise screen wall section - is hollow bulk material filled, with sloping walls and top gutter between them

摘要

The prefabricated component is for erection of protective walls used for reducing traffice noise, esp. along roads. There is a hollow reinforced concrete unit (2-4), forming a section of wall length, for filling with bulk material. This is bounded by two wall panels (6, 7) sloping towards each other and linked by a series of cross beams (8-10). Between them there is a filler gutter (18) on top (17) of the wall (1). There may be recesses in the wall sections, for filling with earth for plant growth. Ends may be fitted with provision for transport onto site.
