Railway Shoulder's drainage system

First, drainage system composition
Railway Shoulder's drainage system usually consists of the following parts:

Drainage ditch:
The gutter is generally located on the outside of the Railway Shoulder, next to the edge of the roadbed.
Side Ditch:
In the cut section, the side ditch is located under the slope on both sides of the roadbed and is used to collect rainwater on the slope.
Gutter and hanging ditch:
Above the cutting slope, the gutter is used to trap the rainwater flowing from the upper level, and the lifting ditch connects the gutter with the side ditch.
Collecting well and pump:
In tunnels or low-lying areas, collection Wells will be set up.
Second, the working principle of drainage system
Natural drainage:
In the relatively flat terrain or moderate slope of the road, rainwater and other fluids can rely on gravity flow out, through the drainage ditch, side ditch and other natural flow to the depression or drainage system.
Forced drainage:
In low-lying or tunnel areas that cannot be drained by self-flow, forced drainage facilities such as collection Wells and pumps need to be set up. When the water reaches a certain level, the pump automatically starts to pump the water to the external drainage system.
Three, drainage system maintenance
Regular cleaning:
Regularly clean drainage facilities such as drainage ditches, side ditches, gutter and hanging ditches to prevent debris from blocking the drainage effect.
Inspection and maintenance:
Regularly check the integrity and function of the drainage system is normal, if there is damage or loss of function effect timely repair.
Reinforcement and transformation:
For the sections that are prone to water accumulation or poor drainage, measures such as strengthening the slope and reforming the drainage facilities can be taken to improve the drainage capacity.
