Underground shiplock arranged in mountain body

Abstract

The invention relates to an underground shiplock arranged in a mountain body, which comprises an upstream approach channel (2) and a downstream approach channel (4) for connecting a shiplock main body section (3), wherein the shiplock main body section (3) comprises an upper lock head (20), a lock chamber (22) and a lower lock head (21), an upstream water-blocking door slot (6) is arranged at theupper lock head (20) of the shiplock, an upstream working door (7) is arranged behind the upstream water-blocking door slot (6), a downstream working door (8) is arranged at the lower lock head (21) of the shiplock, a downstream access door slot (15) is arranged behind the downstream working door (8), and the shiplock adopts a reinforced concrete lining structure. When the shiplock is built on a water conservancy and hydropower junction in a high mountain and valley area, hole excavation is used for replacing open excavation, thereby greatly saving engineering quantity and cost of the shiplock; by matching with construction of a dam, the navigation conditions of an upstream river course and a downstream river course are improved, and a bright future is provided for enabling the river courses to expand the navigable mileage upstream and developing water transportation traffic in mountain areas.

Description

Technical field [0001] The invention relates to a ship lock, more specifically it is an underground ship lock arranged inside a mountain. It arranges the main building of the ship lock inside the mountain and is a fully lined reinforced concrete structure. Background technique [0002] For a pivotal dam site with a narrow river bed and high and steep mountains on both banks, according to the layout requirements, when the ship lock line is located at the high and steep mountain on the river bank, the main structure needs to be deep-cut and excavated, and high and steep excavation slopes are formed on both sides of the gate. To ensure the long-term stability of the excavated slope and meet the requirements of safe operation of the ship lock, the design and construction of the slope reinforcement and support are difficult, and the engineering quantity and cost are high. For large ship locks, this kind of engineering construction can be as small as hundreds of millions. As many as h...

AI Technical Summary

Problems solved by technology

When the overall layout of the hub is carried out at these dam sites, the width of the riverbed is often occupied by flood discharge structures, so that the ship lock cannot be arranged in the riverbed

[0004] Therefore, inventing a new arrangement of ship locks, adapting to the overall layout of the hub dam site with narrow riverbed and high and steep mountains on both sides, and overcoming the shortcomings of difficult engineering construction technology, high engineering quantity and high cost, is a very meaningful project.
