Large scale ship booster supporting compartment manufacture and installation method

Abstract

The invention relates to a method for producing and installing large shift-lift support compartment used in the dam of hydraulic power plant. The invention based on the structure, the character and the transportation demand of compartment utilizes the floating method; divides the support compartment into nut beam floating unit, the main longitudinal floating unit, and the bottom plate embed unit, to be produced in factory, floated to the dam and into the compartment; adjusts the water level of compartment, positions the pier and assembles and welds the units, to connect them integrally. The invention can build the compartment via assembling units on site, to improve the accuracy, quality and reduce the cost.

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
