Problems solved by technology

For large-scale ship lock construction, due to the different rivers and different water heads, simply applying the code selection can no longer meet the requirements of ship lock construction. For hydropower stations with high water heads and cramped hub layouts, it is necessary to make breakthroughs in the layout of water delivery system outlets for navigable buildings. Conventional, research innovative results to meet the layout and operation requirements of high head ship lock outlets

Embodiment Construction

[0014] Such as figure 1 As shown, the structure of the water delivery system in this embodiment has a concrete bottom plate 10 arranged along the direction of water flow, concrete gate piers 9 on both sides of the bottom plate, and a discharge outlet structure section on the side of the river bed (wherein the water outlets are concentrated and independently arranged in the discharge outlet structure. section, so that the water body of the water delivery corridor can directly enter the riverbed on one side). The upstream water flows into the downstream riverbed through a slightly Z-shaped trajectory, which includes: the main floor corridor 8 in the sequentially connected concrete floor 10, the 90° transition corridor 7, and the valve perpendicular to the direction of water flow Corridor 5 (in order to facilitate the maintenance of the staff, there is a valve maintenance well 6 at the corridor), the arc-shaped diffusion section turning corridor 4, the trapezoidal stilling basin ...

Abstract

The invention relates to a navigation lock draining system with an independent porous diversion water outlet structure. The navigation lock draining system with the independent porous diversion water outlet structure effectively solves a plurality of technical problems. The navigation lock draining system is characterized by comprising a concrete floor distributed along the water flow direction, concrete lock piers and a draining opening structure segment close to one side of bed. The navigation lock draining system is characterized in that upland water is drained into an underwater bed from an approximately-Z-shaped water flow track; the water flow track sequentially comprises a main corridor of the floor, a 90-degree transition joining corridor, a valve corridor, an arc expansion segment turning corridor, and a ladder-shaped stilling pool; an outlet of the ladder-shaped stilling pool is joined with the underwater bed; the valve corridor is positioned in a lock pier close to the draining opening structure segment; a group of arc diversion piers are distributed on a junction of the arc expansion segment turning corridor and the ladder-shaped stilling pool along the water flow direction; a slanting ladder-shaped stilling baffle is arranged in the ladder-shaped stilling pool. The navigation lock draining system is suitable for construction of a navigation lock in projects of water conservancy and hydropower, and the like.

Description

technical field [0001] The invention relates to a ship lock drainage system with an independent multi-hole diversion outlet structure, which is suitable for the construction of ship locks in water conservancy and hydropower projects and water transportation and transportation projects. Background technique [0002] The development of navigable structures has a history of 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. Whether the position layout and type selection of the water outlet of the ship lock water delivery system are appropriate are the key factors to ensure the water outlet effect of the ship lock water delivery system and the berthing conditions of ships in the approach channel. According to the current regulations of my country's transportation i...
