SUBSTANCE: ship-raising construction includes a ship-carrying trolley, precast reinforced concrete slabs, a ship-carrying track with inclined and horizontal platforms and is equipped with a metal rack for placement and movement of precast reinforced concrete slabs along it in process of construction erection. The metal rack is made in the form of a metal frame including bearing metal beams with rigidly fixed retaining planks, which form an inclined guiding upper belt /IGUB/ with higher and lower sides, at the same time the higher side of IGUB is installed closely to the coastal ledge, and the lower side is installed with a support to the underwater coastal slope, at its end there is a support of the end block rigidly fixed with the end wall. L-shaped brackets are fixed to the lower side of each precast reinforced concrete slab. In the middle part of each reinforced concrete slab there is a hole for supply of concrete mix. Also the method is proposed to erect a ship-raising construction.

SUBSTANCE: in method samples of soil are picked, density and humidity are determined in natural condition, as well as density of soil particles, overburden pressure at the depth of sample picking and preconsolidation pressure.

FIELD: transportation.

SUBSTANCE: transport system is designed to provide the possibility of transferring vessels through dams of hydropower facilities, weirs and terrain sections between different water basins. A launching trolley 2 with a self-propelled vessel transportation water-filled chamber 3 is lowered into water. A vessel 4 enters the chamber 3, and its shutter closes. The launching trolley 2 with the vessel transportation chamber 3 and the vessel 4 rises to the level of the horizontal slip 5. The vessel transportation chamber 3 with the vessel 4 is moved to the horizontal slip 5, and moves on it to the launching trolley 2 on the other side of the obstacle to be overcome, enters it, after which this launching trolley 2 descends downward along vessel transportation paths 1 to a level sufficient for the vessel 4 to come out of it into the open water area. In the presence of a horizontal vessel transportation path 6, the vessel transportation chamber 3 with the vessel 4 from the launching trolley 2 is moved to a self-propelled transport trolley 7, which moves it to the other end of the horizontal vessel transportation path 6. If there is a curvilinear section 10 on the horizontal vessel transportation path 6, the vessel transportation chamber 3 with the vessel 4 from the self-propelled transport trolley 7 is moved to an additional self-propelled transport trolley 11, on which it moves to the end of the curvilinear section 10, where it moves to the launching trolley 8 and descends to the level sufficient for the vessel 4 to come out of it to the open water area.

EFFECT: simplifying the design of the vessel transportation system and expanding its functional capabilities.
