FIELD: construction engineering. SUBSTANCE: method implies utilization of discarded, worn out and served its life reinforced concrete and using it for production of new reinforced concrete articles. According to method, discarded reinforced concrete article 2 is placed in technological chamber 1, high-voltage electrode 3 is installed, high-voltage electric pulse is sent to electrode from generator. Under action of electric pulse, concrete is crushed, reinforcement gets completely free from concrete. Lumps of concrete are directed to discharge unit 4 were after dewatering they are carried from technological chamber to crushing chamber 5 where concrete lumps are crushed by electric pulses at classificator electrode 6. Crushed concrete is delivered through unloading device 7 to granulometric screen 8 for sorting and conveying to aggregate store 9. Used water from technological chamber 1 and crushing chamber 5 together with crushed concrete of required sizes from aggregate store 9 are directed to concrete mixing unit 10 where concrete mix is made and which is then reloaded to form 11 for producing new reinforced concrete articles. Also placed into form is reinforcement freed from discarded reinforced concrete article 2. EFFECT: high efficiency. 33 cl, 2 dwg |
