This signified a crucial breakthrough in the railway project, as it lays a solid foundation for the project's timely completion and operation.
The Lopburi-Pak Nam Pho section of the double-track railway is located in Central Thailand. Part of the project comprises elevated ballastless track railways and regular ground railways, along with three stations, one of which is reserved for future use.
The completed continuous beam is a pivotal engineering component of the project's bridge section, which has a total length of 2.88 kilometers. It adopts an I-shaped beam and cast-in-place bridge panels. It was designed with a width of 10 meters and a thickness ranging from 0.325 to 0.2 meters.
The entire beam consists of 47 segments, and the pouring method in this phase of the project has broken away from conventional construction methods in Thailand. This has effectively shortened the construction period.
During construction, POWERCHINA overcame numerous challenges and difficulties, including complex geological conditions, a lengthy tropical rainy season, technical standard differences, and tight deadlines.
A series of measures such as optimizing design, fully localizing operations, and quantifying work objectives have been taken to advance the project.
This double-track railway is the largest urban rail transit project in Thailand, with a length of approximately 116 km and a designed speed of 160 km per hour.
Upon completion, it will significantly enhance the railway transportation capacity and operational efficiency in northern Thailand, further driving economic development in Thailand and benefiting the local population.
