Problems solved by technology

For large-scale ship lock construction, due to the different rivers and different water heads, simply applying the codes to select types can no longer meet the requirements of ship lock construction. For medium-water head ship locks between centralized and decentralized water delivery systems, it is very necessary to break through the codes and regulations. Study the irrigation system suitable for the operation requirements of the water head locks at all levels

Embodiment

[0030] Such as figure 1 , image 3 As shown, this embodiment includes a gate head bottom plate 5, a gate head side pier 10, a lock chamber bottom plate 11 and a lock chamber 12. One of the characteristics of this example is to set a water retaining wall connecting the left and right gate head side piers 10. 3 and the head curtain wall 4, five tongue-shaped (trumpet-shaped orifice) water inlets 1 with a large vertical drop are arranged between the water retaining wall and the head curtain wall facing the water flow, and the size of the water inlets It is 2.5×1.2m (height×width), and the bottom of the water inlet is provided with a horizontal corridor 1c. The second feature is that an annular water delivery corridor 2 connecting the upstream side water inlet 1 and the downstream side sluice chamber 12 is provided in the side pier 10 of the gate head, and the water delivery corridor communicates with the transverse corridor 1c. The third feature is that an energy dissipation ch...

Abstract

The invention relates to a water adding system of a ship lock and a construction method thereof. A technical problem to be solved is to provide a water adding system of the ship lock and a construction method thereof. The water adding system has the advantages of high energy dissipation efficiency, full utilization of lock head space, even water level surge height, favourable current joining condition and simple structure, can effectively solve energy and flow state distribution of high-speed current, and can expand new research field for design and type selection of moderate lift lock water delivery system. The technical scheme solving the problem is as follows: the water adding system of the ship lock comprises a lock head baseplate, lock head side blocks, a lock chamber baseplate and a lock chamber. The water adding system is characterized in that a water blocking wall and a lock head screen wall are connected between the lock head side blocks on two sides; a group of tongue-flap shape water inlets with vertical fall are arranged between the water blocking wall and the lock head screen wall; an annular water delivery corridor communicating the water inlet with the lock chamber is arranged in the lock head side block, and an energy consumption chamber is arranged between the outlet end and the water inlet of the annular water delivery corridor. The invention is mainly suitable for water conservancy and hydropower engineering and water transport traffic engineering.

Description

technical field [0001] The invention relates to a water irrigation system of a ship lock and a construction method thereof. Mainly applicable to water conservancy and hydropower projects, 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. In the design of the ship lock, the selection of the water delivery system is 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 water delivery systems: centralized and decentralized water delivery systems. The design and selection are genera...
