Method for launching and floating of ship carrying chamber of ship lift

Abstract

The invention relates to a method for launching and floating of a ship carrying chamber of a ship lift, and belongs to the field of navigation structures of water conservancy and hydropower engineering. A launching type ship lift ship chamber is located in a reservoir, the ship chamber and the lower portion structure of an upper gate bay are submerged under water, under the normal operation condition of the reservoir, the ship lift does not meet the requirement of unwatering the ship chamber, so that the ship carrying chamber can only adopt integral floating. In order to let the ship carrying chamber enter the ship chamber safely and stably in a floating mode, a method which can make the ship carrying chamber enters the ship chamber in a floating mode needs to be designed. The method for launching and floating of the ship carrying chamber of the ship life includes the following steps of prospecting site conditions of the ship lift, understanding the basic information of the ship carrying chamber, building up an organization mechanism of floating of the ship carrying chamber, understanding the basic requirements the ship carrying chamber needs to meet before launching, preparing safety measures before floating, launching the ship carrying chamber, floating and dragging of the ship carrying chamber, and fixing and positioning the ship carrying chamber after entering the ship chamber in a floating mode. The method for launching and floating of the ship carrying chamber of the ship lift is reasonable in design, and considerate.

Description

technical field [0001] The invention relates to a water entry and floating method for a ship-bearing compartment of a ship lift, and belongs to the field of navigable structures of water conservancy and hydropower projects. Background technique [0002] Among the ship lifts that have been built in China at present. The vessel of the Yantan ship lift adopts the method of manufacturing at the downstream wharf and natural floating and launching. A temporary wharf built during the downstream construction period can be used as a processing and assembling yard, and the overflow dam arc gate can be used to adjust the downstream outflow flow. However, it needs to overcome (1) when the ship-holding box floats in the downstream wharf, ensure that the ship-holding box is not washed away by the water flow; (4) Technical difficulties such as the selection of berths for the ship-bearing box. The ship-bearing compartment of the Fujian Shuikou ship lift was built at the Mawei Shipyard ten...

Problems solved by technology

For example, the date of publication is August 1, 2007, and the publication number is CN101008176, which discloses a manufacturing and installation method for a large ship lift cabin. , using the method of floating on water, the ship-bearing compartment is divided into a nut column beam floating unit, a ship-holding compartment main longitudinal beam integral floating unit, and a floor embedding unit; the unit is built as a whole in the factory, and they are floated to The dam; the above units are floated to the ship’s compartment, and assembled and welded after adjusting the water depth of the ship’s compartment, turning over the pier, and positioning accurately; the main longitudinal beam, bottom plate structure and nut column beam of the entire ship’s bearing compartment are connected. As a whole, the manufacturing and installation method of the large-scale ship lift's ship-holding box does not adopt the method of integral floating, and it is difficult to solve the problem that the ship-holding box cannot be assembled because the lower structure of the ship's box room and the upper lock head is submerged underwater
