In the ongoing construction of the Bang Pakong-south Bangkok power plant gas transmission pipeline project in Thailand, a significant breakthrough has been achieved. The first section of the initial phase of pipeline laying, which covers approximately 1km, has been successfully completed using a laying and jacking machine with a diameter of 914mm. The machine, manufactured by CRCHI (China Railway Construction Heavy Industry), is specifically designed for constructing large slope V-shaped longitudinal curves. It overcomes engineering challenges such as accurate long-distance curve guidance, equipment layout, heat dissipation, long-distance power transmission, and rapid and safe propulsion. The machine achieved a stable excavation speed of 600mm per minute and recorded a maximum footage of 48m in two hours. It successfully navigated through the pile foundations of two power towers with precision, marking a technological breakthrough in the construction of ultra-small diameter, ultra-long distance, and ultra-high precision curves.
