近日，江蘇泰信機(jī)械股份有限公司（以下簡稱“泰信機(jī)械”）研制的卡特彼勒底盤旋挖鉆機(jī)KR220C在中泰鐵路橋梁工程及清萊府重大基建項(xiàng)目現(xiàn)場，憑借出色表演，成為破解當(dāng)?shù)貜?fù)雜地質(zhì)的核心設(shè)備之一。這款“樁基礎(chǔ)施工專家”不僅精準(zhǔn)匹配現(xiàn)場樁體施工需求，更在從沙土到中風(fēng)化巖層的多元地質(zhì)中實(shí)現(xiàn)高效鉆進(jìn)，單設(shè)備出勤率超95%，為兩大項(xiàng)目縮短工期、提升施工質(zhì)量提供關(guān)鍵支撐，成為中國裝備賦能東南亞基建的典型案例。

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 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

雙項(xiàng)目攻堅(jiān)：復(fù)雜地質(zhì)下的效能突圍?

Dual-Project Campaign: Efficiency Breakthrough Under Complex Geological Conditions

中泰鐵路橋梁樁工程需攻克 “1-9米白色沙土層 + 10-33米淤泥層 + 34-39米強(qiáng)風(fēng)化紅砂巖” 三層復(fù)雜地質(zhì)，且樁體要求1米直徑、39米深。面對如此復(fù)雜地質(zhì)難題，KR220C通過智能電控系統(tǒng)實(shí)時調(diào)節(jié)鉆進(jìn)參數(shù)：沙土層中以每小時 3.5 米速度連續(xù)鉆進(jìn)無塌孔；淤沙泥層依托液壓功率智能分配技術(shù)，單樁穿越耗時縮短 2.5 小時；強(qiáng)風(fēng)化紅砂巖段啟動一鍵入巖模式，以每小時 1.2 米速度精準(zhǔn)嵌巖。如上施工效率較傳統(tǒng)設(shè)備提升30%，同時沉渣厚度控制在 50mm 內(nèi)，成孔合格率 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 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%.

同期推進(jìn)的清萊府項(xiàng)目，樁體深度達(dá)51米、直徑1米，地質(zhì)涵蓋沙土、強(qiáng)風(fēng)化白沙巖與中風(fēng)化白沙巖。KR220C鎖桿式鉆桿適配極限深度需求，表層沙土保持每小時3米鉆進(jìn)效率，強(qiáng)風(fēng)化巖層中垂直度偏差小于1/300；面對最堅(jiān)硬的中風(fēng)化白沙巖，其220kN?m扭矩配合多級減震設(shè)計(jì)，實(shí)現(xiàn)每小時 0.8 米鉆進(jìn)速度，較當(dāng)?shù)卦O(shè)備提升40% 以上。最終單臺設(shè)備日均完成2根51米深樁，提前兩周完成階段性任務(wù)。?

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.

效能背后：技術(shù)與服務(wù)雙支撐?

Behind the Efficiency: Dual Support from Technology and Services

KR220C 的高效表現(xiàn)，源于“硬件 + 軟件 + 服務(wù)”的全鏈條保障。硬件上，卡特彼勒發(fā)動機(jī)與底盤提供強(qiáng)勁動力與穩(wěn)定作業(yè)平臺，適應(yīng)東南亞雨季泥濘場地；軟件上，全電控系統(tǒng)可針對不同地質(zhì)自動優(yōu)化扭矩、加壓參數(shù)，避免無效能耗。更關(guān)鍵的是，泰信機(jī)械同步派駐售后工程師現(xiàn)場指導(dǎo)，提供參數(shù)調(diào)試與維護(hù)服務(wù)，確保設(shè)備在兩大項(xiàng)目中綜合故障率低于 5%，為高效施工掃清障礙。?

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.

國際認(rèn)可：中國裝備深耕東南亞?

International Recognition: Chinese Equipment Deepening Presence in Southeast Asia

“KR220C完美解決了泰國復(fù)雜地質(zhì)施工痛點(diǎn)，效率遠(yuǎn)超預(yù)期。” 中泰鐵路泰方施工負(fù)責(zé)人評價道。此次雙項(xiàng)目攻堅(jiān)，不僅延續(xù)了該設(shè)備在烏茲別克斯坦、土耳其等國的出色表現(xiàn)，更印證了中國樁工設(shè)備的國際競爭力。隨著中泰鐵路等互聯(lián)互通項(xiàng)目推進(jìn)，KR220C這類 “高效、可靠” 的中國裝備，正成為東南亞基建市場的優(yōu)選，為區(qū)域合作筑牢技術(shù)根基。?

"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.
