The essence of controlled multipurpose circulative system for maintenance of grassed sports grounds in rational use of area of sport ground for a number of purposes and in joining technical-technological imperative demands for rational and high quality maintaining of grass fields from the field of HYDROTECHNOLOGY, HYDROLOGY AND SCIENTIFIC PEDOLOGY. The system provides singular function control of all drainage channels (2-4) with possibility of their cleaning (3/14) with the use of drainage system for dewatering (2-4-5-6) and for capillary irrigation by circulative system which switches mechanical filtration (9-10-11-12-13), chemical control of water composition (16), improving chemical composition of water (18) with a possibility for heating water to a level needed for development of root system and in winter period conditions (20), and reuse of the same water by circulation pump (22), with eventual addition of water from city water supply (21). <i>Construction of multipurpose capacity within the same area and location of the sport ground</i>, from the economical point is also connected with the system for dewatering and circulative capillary irrigation, making the entire system rational, profitable and attractive. |
