Large scale ship booster supporting compartment manufacture and installation method

Abstract

The invention relates to a method for manufacturing and installing a large-scale ship lift for a hydropower station dam. According to the structure of the ship and the characteristics of the ship room and transportation requirements, the ship is divided into two parts by means of floating transportation on water. The floating unit of the nut column beam, the overall floating unit of the main longitudinal beam of the ship-holding box, and the intercalation unit of the bottom plate; the units are built in the factory as a whole, and they are floated to the dam; the above-mentioned units are floated to the ship room, By adjusting the water depth of the ship's compartment, turning over, dropping the pier and positioning it accurately, it is assembled and welded to form; the main longitudinal beam, bottom plate structure and nut column beam of the entire ship's bearing compartment are connected into one. The present invention adopts the whole or large-piece floating transportation method, so that the super-large component ship lift can be built and formed in the factory according to the division of units, and can be installed after being transported to the construction site, which not only makes the ship lift It has high manufacturing precision and good molding quality, which greatly improves the construction efficiency of super-large projects, and at the same time greatly reduces transportation costs.

Description

technical field [0001] The invention relates to a method for manufacturing and installing a large-scale ship lift for a dam of a hydropower station, and is a method for manufacturing and installing a large component or an ultra-large component. Background technique [0002] The ship-holding box of the ship lift used to build the dam of the hydropower station is a super-large steel component, which is composed of the main longitudinal beams arranged on both sides of the longitudinal direction and the bottom plate connecting the main longitudinal beams on both sides. The front and rear are provided with nut column crossbeams for lifting the ship-holding compartment of the ship lift. One of the characteristics of this super-large component is its large size and heavy weight, with a length of 132 meters, a width of 24.1 meters, a height of more than 6 meters, and a weight of more than 3,000 tons. The overall width is about 10 meters, and the weight of the nut post beam is more ...

AI Technical Summary

Problems solved by technology

In order to meet the manufacturing accuracy of super-large components, it is usually necessary to complete the molding in the factory. However, the super-large components after forming can hardly be transported with existing vehicles and conditions. Even if they are transported to the construction site, they are difficult to lift and install, so they can only be scattered However, due to the limited facilities at the construction site, excessive scattered dismantling will make it difficult to guarantee the manufacturing quality of super-large components, and will also affect the strength and mechanical properties of super-large components; It will bring the problems of high construction difficulty and low efficiency
