The State Railway of Thailand’s ( SRT ) double-track railroad is being constructed between Den Chai district in Phrae and Chiang Khong district in Chiang Rai using the technology of arch culverts from Switzerland.
Ekkarat Sriarayanpong, mind of the SRT mayor’s office, said that for the first day in Thailand, the technology is being employed in construction of the first arch culvert in the 323.10- kilometre Den Chai- Chiang Rai- Chiang Khong dual- track railway project.
He claimed that the first for arch bridge is being constructed as part of the railway’s Den Chai- Ngao part in Tambon Pong Pa Wai in the Den Chai area.
The culvert’s installation is anticipated to be finished in two months, he said, and it will bend 33.5 meters long and increase 4.22 meters.
He claimed that the newly developed European technology will help reduce the cost of building bridge conduits by 20 to 25 % and lessen the site’s carbon footprint by reducing the amount of concrete used.
Rather, he said, precast fortified material knocks are produced in a shop before they are taken to the blog to be assembled.
With a full height of up to 4.2 meters from floor to ceiling, he claimed the culvert’s dome design also makes more space for vehicles when passing underneath the railroad.
At least 37 like bridge culverts may be built in this task, 21 in the first part of the rail, another eight in the next and at least eight others in the next section, he said.
The 103.7km first section ( Den Chai- Ngao ), which cost 26.6 billion baht to build, is 6.49 % complete, faster than initially planned.
The 132.3km, 26.89- billion- bass following area ( Ngao- Chiang Rai ) is 7.76 % perfect and even ahead of schedule.
The third and last 87.1km section ( Chiang Rai- Chiang Khong ), which was allocated a 19.38 billion baht budget, is 5.54 % complete and is also ahead of schedule, he said.
He said the new double- track railway, expected to be ready in 2028, will be faster for both passengers and moving merchandise.
He added that it will connect to Kunming, China’s and Laos.
More importantly, he said, this new double-track railway will allow goods from other landlocked nations in the Greater Mekong Sub-region to be transported through Thailand and then shipped to a third destination nation from the Laem Chabang seaport.
