FIELD: construction. ^ SUBSTANCE: draining system of sports ground with manufactured coating and associated construction method is proposed in this invention. The draining system provides for installing at different depth the main line (annular, collecting) draining channels and compacting ground of draining layers filled in with draining and filtering materials. The new feature of the invention is insertion of wrapped in geo-textile corrugated mainline and draining pipes into the mainline and draining channels of sports ground. All profiled and re-compacted surface of granite-crushed stones is coated by geo-textile layer. The whole surface of the above geo-textile layer is filled with compacted, profiled, re-compacted granite screening covered with the second layer of geo-textile. The manufactured coating of sports ground is laid upon the geo-textile layer. Draining system construction technology is also proposed by the invention for the sports ground with manufactured coating. ^ EFFECT: fast and easy method of draining system construction and long-term all-seasonal sports ground operation. ^ 8 cl, 2 dwg |
