Formation of defects in reinforced concrete structures during transportation by rail

The article discusses the provisions on the choice of vehicles for the transportation of prefabricated reinforced concrete structures. The need for the use of railway transport in the delivery of structures may be caused by construction in remote areas of Siberia, as well as the existing location of supplier enterprises.

General-purpose gondola cars, as well as four-axle platforms, are mainly used for transporting structures. The methods of fixing and placing reinforced concrete structures are given.

The main causes of damage to reinforced concrete structures are considered and recommendations for their elimination during transportation are developed. In most cases, structural damage during rail transportation occurs at the moment of collision of wagons when they are improperly lowered from the sorting slides due to displacement or fracture of fasteners under the action of shifting cargo, when the speeds of the platforms exceed the standard ones. The amount of damage is also affected by poor-quality fastening.

The possibilities of loading mass-produced structures into gondola cars and onto platforms are investigated, assuming that they are loaded with reinforced concrete structures of the same weight and size.

The proposals for improving the efficiency of rail transport are presented, including a recommended technical solution with the installation of a frame on a platform for transporting slabs.
