Hi
I am Rahul Welcome to my youtube channel Civil Notebook.
About this video-
Dosto is video me app logo ko batayunga sleeper density in railway engineering ke bare me.
Ummeed Hai Aapko Ye Video Bahut Pasand Aayegi.
Sleeper density is the number of sleepers per rail length.
It is specified as M+x, where M is the length of the rail in metres and x is a number that varies according to factors such as:
(a) axle load and speed
(b) nature of formation
(c) type and strength of the sleepers
(d) type and section of rails
(e) type of ballast and ballast cushion
Sleeper density normally varies from M+3 to M+7 in india
What is a Railway Sleeper?
Railway sleepers are the components on which the rails are arranged with proper gauge. These sleepers generally rests on ballast and is also called as ties in some regions. The load from rails when train passes, is taken by these sleepers and is distributed it to the ballast.
Functions of Railway Sleepers :
hold the rails strongly and to maintain uniform gauge.
transfer the load from rails to the ballast or ground.
reduce the vibrations coming from rails.
offer longitudinal and lateral stability.
Classification of Railway Sleepers :
Wooden sleepers
Concrete sleepers
Steel sleepers
Cast iron sleepers
Composite sleepers
