Ship lock type for silt-laden wandering river

Abstract

The invention relates to the field of water conservancy projects and channel engineering buildings, and provides a ship lock type for a sediment-laden wandering river, which comprises a port entering channel, an offshore ship lock, an underground channel, an alongside ship lock and a plurality of corresponding flushing and drainage systems, a plurality of gates are used for separation between the port entering channel and the offshore ship lock, between the offshore ship lock and the underground channel, and between the underground channel and the docking ship lock. The entrance channel and the ship lock are separated from the main channel through the gate, so that silt is prevented from entering; lifting of the ship is achieved through the flushing and draining system; on the premise that a river channel is occupied as little as possible, on the basis that the flood discharge section is not affected, the ship enters the port and reaches the shore. Meanwhile, three-beach treatment is considered, and high-quality development of the downstream beach area of the Yellow River is achieved.

Description

technical field [0001] The invention relates to water conservancy engineering, channel engineering, ship locks and auxiliary facilities, in particular to a ship lock type suitable for wading rivers with silt and sand so that ships can berth smoothly. Background technique [0002] The Yellow River is a world-famous wandering river with silt and sand. In the lower reaches of the river, it is characterized by less water, more sand, wide and shallow river beaches, and the main channel is mostly wandering and bifurcating. The embankment is 5 to 10 kilometers away from the narrow width, and 24 kilometers at the widest point. The river channel is densely covered with sandbars, and there are many series of ditches. The river swings frequently, and the swing range is 5 to 7 kilometers. complex. Combined with the concept of three beach governance, combined with the implementation of projects such as control and guidance projects, although the main tank can travel, but the main tank ...

Problems solved by technology

All of these make it very difficult to build a suitable wharf in the lower reaches of the Yellow River

The traditional channel uses dredging to achieve a satisfactory water depth, but it is difficult to achieve the desired effect by using traditional dredging methods to ensure the continuous and stable operation of the channel for the Yellow River, which is famous for its silt.

[0003] Traditional wharves often adopt the structural form of steps vertical to the shoreline and solid ramps. As the water level changes, it is necessary to move and store ships back and forth. The operation is frequent and labor-intensive, and the wharf itself
