The Yangzhou Dilong NPD600 slurry balance pipe jacking machine has been successfully launched and put into operation for the Thonburi Wastewater Collection and Treatment System Pipeline Project in Thailand. The official deployment marks the full entry of this overseas environmental infrastructure project into the pipe jacking tunnelling phase, providing solid equipment support for the efficient delivery of the project.

As a key supporting water environment improvement project in Thonburi, Thailand, the initiative focuses on upgrading the urban wastewater collection and treatment system, with a total construction length of 9.3 kilometers. The Yangzhou Dilong NPD600 slurry balance pipe jacking machine is adopted for trenchless tunnelling along the entire route. Systematic and large-scale continuous long-distance jacking operations impose high requirements on equipment overall stability, sustained tunnelling capacity and working condition adaptability.

Developed and optimized by Yangzhou Dilong for overseas municipal environmental pipeline construction, the NPD600 slurry balance pipe jacking machine caters to refined construction requirements of urban wastewater pipelines. Equipped with a mature and reliable slurry balance tunnelling system, the equipment features stable operation, high forming accuracy and low failure rate. It is perfectly suitable for large-scale continuous long-distance jacking tasks, ensuring continuous and standardized tunnelling construction for the full 9.3 km pipeline and effectively overcoming construction challenges including low efficiency and severe equipment wear in long-distance pipeline works.

During construction, Yangzhou Dilong’s professional technical service team provided full-time on-site support with round-the-clock equipment inspection. The team responded promptly to site demands and resolved various technical difficulties, closely coordinating with the contractor to carry out long-distance tunnelling and guarantee steady, orderly, high-quality and efficient project progress.

The Thonburi Wastewater Collection and Treatment System Pipeline Project is a vital livelihood project to improve regional aquatic ecology and complete the urban sewage treatment system. Upon completion, it will greatly enhance local urban wastewater collection, treatment and discharge capacity and lift regional water environment management standards. Meanwhile, the project fully proves the dependable performance of Yangzhou Dilong small-size slurry balance pipe jacking machines for large-scale long-distance construction, further strengthening the competitive edge of domestic trenchless equipment in the Southeast Asian market.
