Bảo Ngọc

On August 25, 2021, the Ministry of Transport of Vietnam issued Circular 17/2021/TT-BGTVTstipulating natural disaster prevention, combat and remediation; incident response and rescue in the railway sector.

According to  Vietnam's Circular 17/2021/TT-BGTVT, disaster prevention for railway works in operation and use is guided as follows:

Regularly inspect and monitor critical positions and railway works that are potentially unsafe when a disaster occurs in order to proactively and promptly overcome or report to competent authorities in Vietnam for a decision on handling measures.

In which, for railways in Vietnam:

- Regularly inspect and cut trees and grass ranges; dredge to clear; repair longitudinal ditches, top ditches, underground water drainage, and roadbed drainage to ensure water drainage when floods occur;

- Create a slope of the curb for water to flow into the trench or down the slope below, create a continuous slope for the ditch to pour water into the sump and exit the road;

- Handle roadbeds and excavated roadbeds to prevent landslides; tarpaulin, leveling to create a plane of sustainability and drainage for the surface of the embankment; cut down trees growing on top of the embankment; handle underground water sources draining to the floodplain (if any).

At critical roadbed positions, reinforcement measures should be taken to enhance stability and sustainability.

More details can be found in Vietnam's Circular 17/2021/TT-BGTVT, effective from October 15, 2021.
