Shipping channels and the Peking ship

It is not known who and when built the first artificial navigable canal on Earth. The oldest known is the Ancient Egyptian, which united the Red Sea during the Middle Kingdom of the Nile. But probably the very first canal builders have faced with a problem that modern engineers have solved a century later.

A ship caisson can go vertically or on a slope, but from the beginning to the end of the voyage, it moves in one direction and in a straight line. This makes possible the use of all balancing schemes. In this case, the relief interfered with this: the raised vessel then needed to be turned and lowered into the water at an angle to the original path. It was impossible to extend the upper or lower reach so that the road become straight, they would have to demolish the mountain. Transport on counterweights cannot be turned to the side, so they had to resort to a solution that is usually avoided all over the world: to put all the work of lifting and lowering on machines.

Special equipment of Peking media

The invention relates to methods for conducting rescue operations at sea and can be used when lifting sunken ships, other underwater objects, including submarines, underwater vehicles and fragments of offshore platforms for the extraction of hydrocarbons.

In practice, rescue operations apply the following known methods of lifting sunken ships:

  • lifting using ship lifting pontoons
  • draining the vessel’s compartments after sealing them (restoring buoyancy)
  • the use of various lifting means
  • filling ship compartments with lightweight materials
  • filling the vessel compartments with foam plastic materials
  • the combined method, including restoring buoyancy and lifting to the surface of the sunken ship by means of pontoons or lifting devices.

Reaching the top, the giant must turn around. It cannot do this by itself. There is a turning circle for this – as in locomotive depot, but much more. The final part of the path remains: down at the same angle (the camera should remain horizontal), but now stern ahead. Entry into the water, the opening of the gate – and the dry dock on the rails send the barge to the water expanses a hundred meters above the starting point.

The use of the invention will improve the efficiency of lifting operations by reducing the complexity and ensuring safety during carrying out lifting operations of large-sized sunken objects.
