Embodiment 1

[0016] This embodiment is a navigation structure through the air at the head and bottom of parallel ship locks, the structure is as follows Figure 1-2 As shown, the width of the diversion navigation structure gradually decreases from the gate head to the approach channel to the end 3; the end 3 of the diversion navigation structure is a solid arc structure, and the arc of the arc structure and the connecting lines on both sides Tangential; the upper part of the part between the end of the diversion navigation structure and the lock head is a solid structure 1 that completely separates the water flow of the double-line ship lock; the lower part of the part between the end of the diversion navigation structure and the lock head is a passable Water-permeable structure 2. In this embodiment, the height of the diversion navigation structure is higher than the highest navigable water level, and the lower permeable structure is located below the draft of the ship at the lowest navig...

Abstract

The invention belongs to the technical field of navigation building hydraulics, and discloses a lock head and pocket floor permeable shunting navigation structure of a paratactic navigation lock. The width of the shunting navigation structure is gradually reduced to the end from a lock head to an approach channel direction; the end of the shunting navigation structure has a solid arc structure; the arc of the arc structure is tangent with connection lines on two sides; the upper part of a portion between the end of the shunting navigation structure and the lock head is in a solid structure capable of completely partitioning water flow of the double-line navigation lock; and the lower part of the portion between the end of the shunting navigation structure and the lock head is in a permeable structure capable of permeating water. The lock head and pocket floor permeable shunting navigation structure has the outstanding advantages of improving the approach channel water flow condition, improving the ship scheduling flexibility, saving engineering investment and being convenient to construct.

Description

technical field [0001] The invention belongs to the technical field of hydraulics of navigable structures, and in particular relates to a navigation structure for penetrating space at the head and bottom of parallel ship locks. Background technique [0002] The arrangement of navigation structures and flow-blocking structures between parallel double-line ship locks will directly affect the water flow conditions in the approach channel of the other line of ship locks and the water flow conditions in the entrance and exit of the other line of ship locks during water delivery, as well as the navigation safety of ships entering and leaving the other line of locks. If the arrangement is not proper, a relatively large reverse flow may be generated in the inlet and outlet of the other line of ship locks when the water is delivered to the other line of ship locks, which will have an adverse effect on the operation safety of the miter gates of the other line of ship locks, or large S...
