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 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 1 meter, 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
For the bridge pile engineering of the China-Thailand Railway, it is necessary to tackle three layers of complex geology: 1-9m white sand layer, 10-33m black silty mud layer, and 34-39m strongly weathered red sandstone. Additionally, the piles require a diameter of 1 meter and a depth of 39 meters. Facing the challenges of the sand layer being prone to hole collapse, high resistance in the silty mud layer, and high hardness of the red sandstone, the KR220C adjusts drilling parameters in real time through its intelligent electronic control system: in the sand layer, it drills continuously at a speed of 3.5 meters per hour without hole collapse, achieving a 40% efficiency improvement compared to traditional equipment; in the silty mud layer, relying on the intelligent hydraulic power distribution technology, the time required to penetrate a single pile is reduced by 2.5 hours; in the strongly weathered red sandstone section, it activates the one-click rock entry mode, embedding into the rock accurately at a speed of 1.2 meters per hour. The sediment thickness is controlled within 50mm, and the hole formation qualification rate reaches 100%.
The Chiang Rai Province project advanced in the same period requires piles with a depth of 51 meters and a diameter of 1 meter, and the geology covers sand, strongly weathered white sandstone and moderately weathered white sandstone. The rod-locking drill pipe of the KR220C adapts to the ultra-depth requirement: it maintains a drilling efficiency of 3 meters per hour in the surface sand layer, and achieves a verticality deviation of less than 1/300 in the strongly weathered rock layer. Facing the hardest moderately weathered white sandstone, its 220kN・m torque, combined with the multi-stage shock absorption design, enables a drilling speed of 0.8 meters per hour—more than 50% higher than that of local equipment. In the end, a single piece of equipment completed an average of 1.5 51-meter-deep piles per day and finished the phased task 12 days ahead of schedule.
Behind the Efficiency: Dual Support from Technology and Services
The high-efficiency performance of the KR220C stems from the full-chain support of "hardware + software + services". On the hardware front, the Caterpillar engine and chassis provide powerful power and a stable operating platform, adapting to the muddy sites during Thailand's rainy season. On the software front, the full electronic control system can automatically optimize torque and pressure parameters for different geological conditions, avoiding ineffective energy consumption. More importantly, TYSIM simultaneously dispatches engineers to provide on-site guidance, as well as parameter debugging and maintenance services. This ensures the comprehensive failure rate of the equipment in the two projects is less than 5%, clearing obstacles for efficient construction.
International Recognition: Chinese Equipment Deepening Presence in Southeast Asia
"The KR220C has perfectly addressed the pain points of construction in Thailand's geological conditions, and its efficiency far exceeds expectations," commented the Thai construction supervisor of the China-Thailand Railway. This two-project campaign not only continues the equipment's outstanding performance in countries such as Uzbekistan and Turkey, but also confirms the international competitiveness of Chinese piling equipment. With the advancement of connectivity projects like the China-Thailand Railway, high-efficiency and reliable Chinese equipment such as the KR220C is becoming a preferred choice in the Southeast Asian infrastructure market, laying a solid technical foundation for regional cooperation.
