However, in the rivers in the southeast coastal cities of my country, the riverbed is generally only a few meters long. Considering the navigation under the bridge, the bridge must be built very high, generally more than 20 meters. , and also occupied a large amount of land due to the slope problem, and most of them had to demolish more buildings and relocate more residents
After the completion, the passing vehicles must also climb the slope, and some vehicles have to detour to increase the driving distance, which also leads to increased energy consumption and transportation costs

Example Embodiment

[0011] The specific implementation method of the present invention will be further described below in conjunction with the embodiments.

[0012] When a 30-meter-high ship (including the underwater part) is going to pass the bridge with a height of 20 meters from the bottom of the bridge to the water level of the channel, the ship enters the lock, closes the lock gate, and activates the pumping equipment to pump the lock water out of the lock In addition, the water level in the ship lock drops, so that the ship also begins to drop. When the height of the vessel drops below the bottom of the bridge, turn off the pumping equipment. If the ship lock is fixed, the ship is directly driven through the bottom of the bridge in the ship lock; if the ship lock is movable or not equipped with power, the ship lock and the ship are pulled through the channel at the bottom of the bridge together with the power ship, and the activity is equipped with power equipment. As for the ship lock, it will...

Abstract

The invention discloses a boat running method in low bridge sea-route. It constructs the tail gate in the bridge bottom, when the boat in the sea-route, the tail gate is opened and the boat is in the tail gate; when the door is closed, the water in tail gate is pumped out and the boat height is to decrease according to the bridge; one method is the boat only passes the bridge bottom while the tail gate is fixed on the bridge sea-route; the other is the tail gate is movable and the tail gate is pulled or through the seal-route. Then the water is drained into the gate when it reaches the out level, the boat is out of the tail gate. The invention is proper for all kinds of the sea-route in high boat and low bridge.

Description

technical field [0001] The invention relates to a method for sailing a ship in a bridge bottom channel with a high ship and a low bridge, which belongs to the field of fixed buildings. Background technique [0002] At present, the demonstration of building bridges generally considers the problem of navigation under the bridge first. However, in the rivers in the southeast coastal cities of my country, the riverbed is generally only a few meters long. Considering the navigation under the bridge, the bridge must be built very high, generally more than 20 meters. , and also occupied a large amount of land due to the slope problem, and most of them had to demolish more buildings and relocate more residents. Passing vehicles also have to climb slopes after completion, and some vehicles have to detour to increase the driving distance, which also leads to increased energy consumption and transportation costs. Taking the Nanjing Yangtze River Bridge as an example, the length of the...
