Aquatic floating and transportation method of ultra-large type component

Abstract

The invention relates to waterborne floating transporting method used when construct super sized component such as dams for the power stations and bridges. Its program is: detecting fairways, forming sealed compartment with the cross beam and / or the longitudinal beam of trunk section of super sized component, forming inflatable air chamber with the within web of said cross and longitudinal beam; connecting the inflatable air chamber with compressed air source, putting the super component in waterborne fairways; aerifying the inflatable air chamber and forming air cushion between it and the surface and leading to the giant component floating on the water; regarding the towboat as power and driving the super component into waterways to floating and transporting. Its features are: installing independent ballast water tank on the both ends of longitudinal beam on the both sides of super component, ballast water tank is linked with the ballast pumping system to adjusting the ballast water of each ballast water tanks. The adaptability to component structure of the invention is better, adjustment and balance is easy and convenient to completing when in water run-time, so the overall floating and transporting performance of super component is more perfect.

Description

technical field [0001] The invention relates to a method for floating on water for super-large components such as construction of power station dams and bridges, in particular to a method for floating on water as a whole of the main longitudinal beam of a ship-bearing compartment of a dam ship lift, which is an improvement on the existing method for floating on water further improvement. Background technique [0002] One of the characteristics of large steel components used in the construction of hydropower dams and bridges is their large size and heavy weight. For example, the ship lift compartment used for hydropower dams is more than 100 meters long and 100 meters wide. From a few meters to more than 20 meters, the height is ten meters, and the weight can reach several thousand tons; the second feature is that the cross-section of the longitudinal beam and part of the beam is a hollow box structure, and has the structural characteristics of a low outer periphery below the...

AI Technical Summary

Problems solved by technology

A key issue in water transportation of super-large components is to maintain the balance of component operation to prevent the air cushion from leaking and failing. This patent is to adjust the balance of component floating by supplementing air in different air chambers, and the left and right of component floating The balance is adjusted by setting the left and right air chambers. For large components with no longitudinal partitions in the structure to form the left and right air chambers, there is a problem that the left and right heels cannot be adjusted during floating transportation. This will not only greatly increase the difficulty of floating transportation, but the situation is serious. will lead to the failure of floating

However, adding longitudinal partitions on large components to form left and right air chambers will not only damage the structure of the components to a certain extent, but also greatly increase the cost of component fabrication and assembly.
