Lock head and pocket floor permeable shunting navigation structure of paratactic navigation lock

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...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to: in order to solve the technical problems existing in the layout of the existing navigation and flow-blocking structures in the above background technology, a kind of navigation structure through the head and bottom of parallel ship locks is proposed, which can reduce the impact of single-line ship lock operation on the other line when the water level is low. The influence of ship locks can improve the water flow conditions of the approach channel, increase the flexibility of ship dispatching, reduce the distance between parallel double-line ship locks, and reduce project investment
