Work At Aviemore On Tunnel Gate
(New Zealand Press Association)
OAMARU, July 8.
With just two years to go before Aviemore begins producing hydro-electric power for the national grid, workmen have started assembling the 118-ton diversion tunnel gate which will block the Waitaki river and form a man-made lake of 12 square miles.
This gate, which will drop shut early in 1968, will be made in two parts— a top section of 56 tons and lower section of 62 tons. Girders for each section were manufactured in Christchurch. Two steel sections of the first of four penstocks have been set in the concrete dam.
i When completed, each pen- , stock will have an internal diameter of 23ft, the largest ' in New Zealand. Each Is in 13 ’ sections from 10ft to 15ft long ' and weighing up to 18 tons. Progress on the concrete dam is continuing steadily, > with four of the 18 dam i blocks at top height and an- • other seven at varying stages of completion. The nominal height of the dam will be 186 ft
