METHOD FOR AUTOMATIC LAYING AND COMPACTING CONCRETE MIXTURE Russian patent published in 1996 - IPC

FIELD: civil engineering. SUBSTANCE: method for automatic laying and compacting concrete mixture includes transporting concrete mixture under pressure along a pipeline, concreting the construction by sections according to sequence of operations predetermined in advance, layer-by-layer concrete compacting, determination of time to supply concrete mixture into the pipeline. Then concrete mixture compacting, measuring thickness of the layer being laid and comparison the same with predetermined one, determination of compact extent of the concrete mixture in each layer begins. Section concreting is finished after achievement preset height. Then pipeline is transported to the next section. EFFECT: high speed of concreting. 5 dwg
