Arrangement mode and structure of small ecological flow unit of hydropower station underground powerhouse
The invention discloses an arrangement mode and structure of a small ecological flow unit of a hydropower station underground powerhouse. According to the arrangement mode and structure, pressure steel tubes of water diversion lines (1) of a large unit, close to the riverbed side, of an original water diversion and power generation system are perforated and branched for the arrangement of water diversion lines (1) of the small unit. The small ecological flow unit (2) is arranged at the position, where auxiliary powerhouses are arranged originally, of the end, close to the riverbed side, of an underground powerhouse main engine chamber (4). The lower portion of an installation chamber (5) is expanded and excavated, part of the auxiliary powerhouses are moved to the lower portion of the installation chamber (5), and the other part of the auxiliary powerhouses are moved to the side, close to the riverbed, of the small ecological flow unit (2). According to the technical scheme of the arrangement mode and structure, an existing hydraulic structure is fully used, and the coordinative and reasonable arrangement of whole hub buildings is considered, so that huge investment is saved, the economical benefit is remarkable, construction is safe and convenient, and the arrangement mode and structure are worth popularizing.
