METHOD TO REDUCE LOAD AT RETAINING STRUCTURES OF TSIMLYANSKIY WATER-ENGINEERING SYSTEM

摘要

FIELD: construction.;SUBSTANCE: method includes erection of flow-through dams with locks and connection canals. To lower water level upstream the dam of the Tsimlyanskiy water-engineering system, the "Eastern part of the Tsimlyanskoe storage pond is isolated from its "Western" Part by erection of a separation dam in the water area of the Tsimlyanskoe storage pond and a flow-through dam with locks in rock bases of the island "Kozhevenniy" in the bay near the mouth of the river Chir into the Tsimlyanskoe storage pond close to the existing fairway in the water area of the Tsimlyanskoe storage pond. From the "Eastern" part of the Tsimlyanskoe storage pond between the bay in the mouth of the river "Aksay-Kurmoyarskiy" and the "Dubovskoe" stoage pond, in the valley of the river Sal, the fairway "Aksay-Sal" is constructed. Also the "Volgodonskoe branch" is constructed from the fairway "Aksal-Sal", which is designed to supply water to cooling ponds of the Rostov nuclear power plants near the town of Volgodonsk and to city water intakes. Continuous water level is maintained in the riverbed at the elevation of +36 metres, supported with the retaining flow-through dam with locks, providing for transition of vessels from the water level in the "Aksay-Sal" canal equal to +36 metres, to the water level in the "Dubovskoe" storage pond. The "Dubovskoe storage pond is developed for supply of water to the "Semikarakorskaya" branch of the fairway from the "Dubovskoe" storage pond to the retaining flow-through dam with locks designed for transition of vessels from the "Semikarakorskaya" branch of the fairway into the Don river.;EFFECT: reduced loads at retaining structures of the Tsimlyanskiy water-engineering system and safe conditions for navigation.;2 cl
