近日，江苏泰信机械株式会社（如下简称“泰信机械”）研制的卡特彼勒底回旋挖钻机KR220C于中泰铁路桥梁工程和清莱府庞大基建项目现场，依附精彩演出，成为破解本地繁杂地质的焦点装备之一。这款“桩基础施工专家”不仅精准匹配现场桩体施工需求，更于从沙土到中风化岩层的多元地质中实现高效钻进，单装备出勤率超95%，为两年夜项目缩短工期、晋升施工质量提供要害支撑，成为中国设备赋能东南亚基建的典型案例。

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 1000妹妹, 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

双项目攻坚：繁杂地质下的效能突围

Dual-Project Campaign: Efficiency Breakthrough Under Complex Geological Conditions

中泰铁路桥梁桩工程需霸占 “1-9米白色沙土层 + 10-33米淤泥层 + 34-39米强风化红砂岩” 三层繁杂地质，且桩体要求1米直径、39米深。面临云云繁杂地质难题，KR220C经由过程智能电控体系及时调治钻进参数：沙土层中以每一小时 3.5 米速率持续钻进无塌孔；淤沙泥层依托液压功率智能分配技能，单桩穿越耗时缩短 2.5 小时；强风化红砂岩段启动一键入岩模式，以每一小时 1.2 米速率精准嵌岩。如上施工效率较传统装备晋升30%，同时沉渣厚度节制于 50妹妹 内，成孔及格率 100%。

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 1000妹妹 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 50妹妹 and the hole formation qualification rate reaches 100%.

同期推进的清莱府项目，桩体深度达51米、直径1米，地质涵盖沙土、强风化白沙岩与中风化白沙岩。KR220C锁杆式钻杆适配极限深度需求，表层沙土连结每一小时3米钻进效率，强风化岩层中垂直度误差小在1/300；面临最坚硬的中风化白沙岩，其220kN・m扭矩共同多级减震设计，实现每一小时 0.8 米钻进速率，较本地装备晋升40% 以上。终极单台装备日均完成2根51米深桩，提早两周完成阶段性使命。

In the same period, the Chiang Rai project requires piles to be 51m deep and 1000妹妹 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.

效能暗地里：技能与办事双支撑

Behind the Efficiency: Dual Support from Technology and Services

KR220C 的高效体现，源在“硬件 + 软件 + 办事”的全链条保障。硬件上，卡特彼勒策动机与底盘提供强劲动力与不变功课平台，顺应东南亚雨季泥泞园地；软件上，全电控体系可针对于差别地质主动优化扭矩、加压参数，防止无效能耗。更要害的是，泰信机械同步派驻售后工程师现场引导，提供参数调试与维护办事，确保装备于两年夜项目中综合妨碍率低在 5%，为高效施工扫清障碍。

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.

国际承认：中国设备深耕东南亚

International Recognition: Chinese Equipment Deepening Presence in Southeast Asia

“KR220C完善解决了泰国繁杂地质施工痛点，效率远超预期。” 中泰铁路泰方施工卖力人评价道。这次双项目攻坚，不仅延续了该装备于乌兹别克斯坦、土耳其等国的精彩体现，更印证了中国桩工装备的国际竞争力。跟着中泰铁路等互联互通项目推进，KR220C这种 “高效、靠得住” 的中国设备，正成为东南亚基建市场的优选，为区域互助筑牢技能根底。

“KR220C has perfectly addressed the construction pain points in Thailand's complex geological conditions, with efficiency far exceeding expectations," co妹妹ented 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.
