Broken-line ship lock approach channel dike and its layout method

An approach channel and broken-line technology, applied in the directions of ship locks, ship lifting devices, buildings, etc., can solve the difficulty of smooth connection between the approach channel and the mainstream of the river, the length of the straight section of the dike is difficult to meet the requirements, and it is difficult to meet the ship lock approach channel. Problems such as the requirements for the straight line arrangement of the navigation section, the adjustment section and the berthing section to achieve the effect of improving the navigable water flow conditions

Problems solved by technology

The above regulations can still be satisfied for plain rivers, but in mountainous rivers, due to the many bends in the river, the hubs are generally arranged on bends or slightly curved river sections, which makes it difficult to meet the requirements of straight line layout of the navigation section, alignment section and berthing section of the approach channel of the ship lock. It is difficult to meet the requirements for the length of the straight line section of the corresponding dike
In addition, when the straight line section is arranged according to the above requirements, it is also difficult to smoothly connect the approach channel with the mainstream of the river

Embodiment 1

[0021] This embodiment illustrates the design principle and specific scheme of the arrangement method of the present invention.

[0022] 1. Necessary conditions for the layout method of the broken-line dike in the approach channel of the ship lock

[0023] (1) The ship lock is arranged in the slight bend or curve section of the restricted river section on both sides of the mountain

[0024] ①Water conservancy projects are arranged in slightly curved or curved river sections with limited river width. In order to ensure the requirements for ships entering and leaving the lock, the lock chamber and the navigation section of the approach channel must be arranged as straight sections. It is difficult to meet the requirements stipulated in the "Code for the Overall Design of Ship Locks" for the length of the alignment section and the straight section of the berthing section.

[0025] ②Restricted by factors such as mountains on both sides of the river, other existing buildings, cult...

Embodiment 2

[0045] Embodiment Taking a river section in a mountainous area as an example, the method for arranging the barrier embankment of the present invention is described in detail.

[0046] Traditional dike + layout such as figure 2 As shown, the ship lock is arranged on the slightly curved or curved river section restricted by the mountains on both banks. It needs to be arranged together with other hydraulic structures on the shore side of the river. In order to ensure that the length of the straight line section of the approach channel and the water flow conditions in the approach channel meet the requirements, It is necessary to set up a longer navigation diversion embankment. Affected by the river bend, the longer the diversion embankment, the larger the angle between the outlet of the downstream approach channel and the mainstream water flow of the river, and the worse the navigable water flow conditions in the channel of the entrance area; The longer the embankment is, the la...

Abstract

The invention relates to a broken-line type ship lock approach channel breaker and an arrangement method. After arranging the upper section breaker that meets the requirements of the ship lock approach channel and the required straight section length of the breaker, it rotates to the river bank side. a Continue to arrange the lower part of the dike at an angle to form a broken line type dike; the upper and lower part of the dike are arranged in a straight line. The present invention overcomes the problems caused by the traditional method of dividing the dike arrangement in the application of multi-curve mountain rivers, and adopts the design of the folded dike, so that the approach channel and the main stream of the river are smoothly connected, and the navigable water flow in the waterway in the entrance area is improved. condition.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a break-line type ship lock approach channel diverge and an arrangement method thereof. Background technique [0002] As an important part of the approach channel of the ship lock, the dike divides the river flow to form a slow flow or still water area in the approach channel, so as to meet the requirements of ships passing the lock to safely enter and exit the lock and waiting gate through the approach channel. The dike generally follows the approach channel The arrangement form is arranged on the river side. Whether the arrangement of the approach channel dike is appropriate or not has a great influence on the safe and smooth passage of ships, the capacity of the ship lock, project investment and benefits, and is one of the keys to the success of the ship lock arrangement. [0003] In the "Code for the Overall Design of Ship Locks", there are ...
