Title: Constructing composted waste wall as noise barrier
Inventor: LUFTENEGGER FERDINAND
IPC: G10K11/16
Filed: 1983-08-08
Abstract: The wall is made of a compost of waste material which may be supplemented with clayey, mineral materials. Pref. layer-upon-layer, moist compost is packed into a preformed envelope of wire netting, wattle or other pervious material which yields under filling pressure. Before packing into the envelope, the waste is screened to retain only particle sizes between 0.01-5.0(0.06-20) mm. In free flow state, the waste has an apparent specific wt. of 600-900 g/l pref. 750 g/l and a water content of 35-50%, pref. 48%. The waste is compacted in the normal way inside the envelope. Pref. the envelope is completely filled with compost which, in its moist state, then has a specific wt. between 0.95-1.1 t/cubic m. The wall is pref. of trapezoidal cross-section with a base which is wider than its top. A central, vertical upright which anchors into the ground has cross bars at the top and at ground level to which the wire netting etc. is fixed. Grass and/or plants are pref. grown over the surface of the wall by rooting into the compost through the envelope. Used for outdoor walls to reduce noise nuisance, e.g. from motorways, factories, airports, etc. Aesthetically pleasing walls can be inexpensively constructed very quickly from waste material which has previously presented a disposal problem.
