Recently, at the construction sites of the China-Thailand Railway Bridge Project and the major infrastructure project in Chiang Rai Province, the KR220C rotary drilling rig with CAT chassis of TYSIM Piling Equipment Co., Ltd. (hereinafter referred to as "TYSIM") has become a core equipment for solving local complex geological problems by virtue of its 220kN·m maximum output torque and intelligent adaptation capability. This "pile foundation expert" not only accurately meets the construction requirements for pile bodies with a diameter of 1000mm, but also achieves efficient drilling in diverse geologies ranging from sandy soil to moderately weathered rock formations. With a single equipment availability rate of over 95%, it provides key support for shortening the construction period and improving the quality of the two projects, and has become a typical case of Chinese equipment empowering infrastructure construction in Southeast Asia

Dual-Project Campaign: Efficiency Breakthrough Under Complex Geological Conditions Dual-Project Campaign: Efficiency Breakthrough Under Complex Geological Conditions For the bridge pile project of the China-Thailand Railway, three complex geological layers need to be overcome: 1-9m white sand layer, 10-33m muck layer, and 34-39m strongly weathered red sandstone. The piles require a diameter of 1000mm and a depth of 39m. To address these geological challenges, the KR220C adjusts drilling parameters in real time via its intelligent electronic control system: it drills continuously at 3.5m/h in the sand layer without hole collapse; in the muck layer, it uses intelligent hydraulic power distribution technology to reduce the single-pile penetration time by 2.5 hours; in the strongly weathered red sandstone section, it activates the one-click rock entry mode for accurate rock embedding at 1.2m/h. Its construction efficiency is 30% higher than that of traditional equipment, while the sediment thickness is controlled within 50mm and the hole formation qualification rate reaches 100%.

Its construction efficiency is 30% higher than that of traditional equipment, while the sediment thickness is controlled within 50mm and the hole formation qualification rate reaches 100%. In the same period, the Chiang Rai project requires piles to be 51m deep and 1000mm in diameter, with geological conditions including sand, strongly weathered white sandstone and moderately weathered white sandstone. The KR220C rod-locking drill pipe meets the ultra-deep requirement: it maintains a drilling efficiency of 3m per hour in the surface sand layer, and the verticality deviation is less than 1/300 in the strongly weathered sandstone. For the hardest moderately weathered white sandstone, its 220kN・m of torque, combined with multi-stage shock absorption design, achieves a drilling speed of 0.8m per hour—over 40% higher than local equipment. Eventually, a single unit completed 2 piles (51m deep each) daily, finishing the phased task two weeks ahead of schedule.

Behind the Efficiency: Dual Support from Technology and Services Behind the Efficiency: Dual Support from Technology and Services The high-efficiency performance of the KR220C stems from full-chain support covering "hardware + software + service". In terms of hardware, its Caterpillar engine and chassis provide strong power and a stable operating platform, adapting to muddy sites during Southeast Asia's rainy season. For software, the full electronic control system automatically optimizes torque and pressure parameters for different geological conditions, avoiding unnecessary energy consumption. More importantly, TYSIM simultaneously dispatches after-sales engineers for on-site guidance, offering parameter adjustment and maintenance services. This ensures the comprehensive failure rate of the equipment in both projects is below 5%, clearing obstacles for efficient construction.

International Recognition: Chinese Equipment Deepening Presence in Southeast Asia International Recognition: Chinese Equipment Deepening Presence in Southeast Asia “KR220C has perfectly addressed the construction pain points in Thailand's complex geological conditions, with efficiency far exceeding expectations," commented the Thai construction director of the China-Thailand Railway. These two project challenges have not only continued the equipment's outstanding performance in countries like Uzbekistan and Turkey, but also confirmed the international competitiveness of Chinese piling equipment. As connectivity projects such as the China-Thailand Railway move forward, highly efficient and reliable Chinese equipment like the KR220C is becoming the preferred choice in Southeast Asia's infrastructure market, laying a solid technical foundation for regional cooperation. “KR220C has perfectly addressed the construction pain points in Thailand's complex geological conditions, with efficiency far exceeding expectations," commented the Thai construction director of the China-Thailand Railway.
