3.4 MODERN FASTENING OF REINFORCED CONCRETE SLEEPERS IN THE RAILWAY

Abstract

Analysis of the working conditions of fasteners, which are one of the main elements of the road safety device in ensuring high-speed safe movement of trains on high-speed railways.

Since 2004, on the main lines of JSC " Uzbekistan railways ", reinforced concrete sleepers of the modern BF70 type with an elastic intermediate rail bond of the "Pandrol Fastclip" type (England) have been laid and operated on a large scale. BF 70 sleepers have the strength parameters of sleepers on average 25-30% higher than those of the sh-1 type. This allows them to be installed and operated on main lines of any class, including high-speed and high-speed lines, as well as sections with increased axial loads [1.2.3.4.5.6.7].
