Under-sill water delivery energy dissipation structure and construction method thereof

Abstract

The invention relates to an under-sill water delivery energy dissipation structure and a construction method thereof. The invention aims at providing the under-sill water delivery energy dissipation structure which is simple in simple, convenient to construct and high in energy dissipation efficiency and the construction method of the under-sill water delivery energy dissipation structure. According to the technical scheme, the under-sill water delivery energy dissipation structure is provided with a lock head bottom plate, a lock head curtain wall and lock side walls, wherein the lock head curtain wall is poured onto the lock head bottom plate, and the lock side walls are on the two sides of the lock head curtain wall. The under-sill water delivery energy dissipation structure is characterized in that a water retaining vertical plate is built in the position, a certain distance spaced from the lock head curtain wall, of the lock head bottom plate on the upstream side of the lock head curtain wall; a perpendicular water delivery vertical well is formed between the water retaining vertical plate and the lock head curtain wall; energy dissipation devices are arranged in the perpendicular water delivery vertical well; the lower portion of the perpendicular water delivery vertical well communicates with water inlets of a plurality of sudden expansion chambers reserved at the bottom of the lock head curtain wall; and water outlets of the sudden expansion chambers communicate with a ship lock chamber through a water delivery gallery reserved in a lock bottom plate on the downstream side of the lock head curtain wall. The under-sill water delivery energy dissipation structure and the construction method thereof are suitable for water conservancy and hydropower engineering and water transportation traffic engineering.

Description

technical field [0001] The invention relates to an under-sill water conveyance and energy dissipation structure and a construction method thereof. Applicable to water conservancy and hydropower projects, water transportation and transportation projects. Background technique [0002] The development of navigable structures has a history of more than 2,000 years, and nearly 4,000 ship locks have been built around the world. The history of ship lock construction in my country is very long, and nearly 800 ship locks have been built so far, accounting for about 20% of the total number of ship locks in the world. In the design of the ship lock, the type selection of the water delivery system and the advantages and disadvantages of the energy dissipation structure type are one of the most critical technologies to ensure the efficient and safe operation of the ship lock. According to the current regulations of my country's transportation industry, there are mainly two types of wat...

Problems solved by technology

For large-scale ship lock construction, due to different rivers and different water heads, the selection of models simply according to the norms can no longer meet the requirements of ship lock construction. For the type selection of high water head, large flow, narrow river bed, and non-standard ship lock water delivery system, it is necessary to break through the norms stipulations, research innovative achievements, in order to meet the layout and operation requirements of ship locks with different water heads at all levels
