Abstract

Винахід стосується удосконалення тунелів для підведення води до гідроагрегатів електростанцій. Запропонований спосіб знижує втрати енергії потоку на тертя у порівнянні з необлицьованими тунелями або іншими тунелями з шорсткими поверхнями стінки і/або змінним поперечним перерізом. Для цього у тунель вводять гнучку або жорстку трубу, поперечний переріз якої дорівнює або є дещо меншим за найбільший круглий відкритий поперечний переріз тунелю. Трубу закріплюють у тунелі до певних точок стінки тунелю. Передбачено застосування засобів підтримання у трубі надлишкового внутрішнього тиску порівняно із зовнішнім тиском під час протікання потоку. Винахід скорочує питомі втрати енергії потоку на тертя по стінках тунелю у 3-4 рази.
