Title: Sand-packed unit production process - fills hopper lined with packing material which is closed over sand
IPC: E02D15/10
Filed: 1974-06-25
Abstract: The process is particularly for the construction of wave-breakers, dams etc, using sand or similar material. The inner surface of a hopper (1) is clad with packing material (2), after which it is filled with sand (6) and the packing material closed over the latter. The packed unit is then released at the site of the dam etc. to be built. The hopper can be mounted on a vehicle, dividing in halves to release the unit. The packing material can be permeable to water but no sand, and can be not completely filled with sand. The process involves the handling of much less sand in all than with conventional methods, as the sand does not wash away after placement.
