近日，江蘇泰信機械股份有限公司（以下簡稱“泰信機械”）的三款定制化旋挖鉆機：KR220、KR165、KR125憑借卓越性能成為中烏兩國在基礎(chǔ)設(shè)施建設(shè)領(lǐng)域深化合作的核心力量，為項目高效施工提供了關(guān)鍵保障。烏茲別克斯坦伊斯蘭街下穿隧道項目作為該國提升城市交通格局的關(guān)鍵工程，自啟動以來便受到廣泛關(guān)注。泰信機械憑借其先進的樁工設(shè)備和豐富的施工經(jīng)驗，成為該項目施工的重要參與者，為項目的順利推進提供了堅實保障。

Recently, three customized rotary drilling rigs from Jiangsu TYSIM Piling Equipment Co., Ltd. (hereinafter referred to as "TYSIM") — KR220, KR165 and KR125 — have become a key force in deepening cooperation between China and Uzbekistan in infrastructure construction, thanks to their excellent performance. They provide key support for the efficient construction of projects. Uzbekistan's Islam Street Underpass Tunnel Project, a key project to improve the country's urban transportation layout, has attracted wide attention since it started.  

With its advanced piling equipment and rich construction experience, TYSIM has become an important participant in the project's construction, offering solid support for the smooth progress of the project.

復(fù)雜地質(zhì)輕松克服，施工效率提升?

Complex Geology Easily Overcome, Construction Efficiency Up

該項目施工區(qū)域的地質(zhì)條件復(fù)雜，給樁基施工帶來了巨大挑戰(zhàn)。從地表往下，0~1米是水泥硬化路面與沙卵石回填層，堅硬且結(jié)構(gòu)松散，對設(shè)備的入巖和鉆進能力是極大考驗；1~5米為粉質(zhì)粘土層，粘性大，易造成鉆頭堵塞；5~7米的粗砂層，穩(wěn)定性差，極易發(fā)生塌孔；7~28米的粘泥層，質(zhì)地粘稠，鉆進阻力大，效率難以保證。?

The geological conditions in the project's construction area are complex, posing great challenges to pile foundation construction. From the surface down, the 0-1 meter layer is a cement-hardened road surface and sand-gravel backfill, which is hard yet loosely structured, putting a big test on the equipment's rock penetration and drilling abilities. The 1-5 meter layer is silty clay, with high viscosity, which easily clogs the drill bit. The 5-7 meter layer is coarse sand, with poor stability, making hole collapse very likely. The 7-28 meter layer is clayey mud, thick and sticky, leading to high drilling resistance and making it hard to ensure efficiency.

泰信機械研制的KR220、KR165、KR125三款旋挖鉆機展現(xiàn)出了卓越的性能。KR220 擁有強大的扭矩輸出和鉆進動力，在7~17米的粘泥層施工中，能夠輕松克服粘稠土壤帶來的阻力，保證成孔效率和質(zhì)量；KR165則憑借其精準的控制和穩(wěn)定的作業(yè)性能，在5~7米的粗砂層施工中，通過優(yōu)化泥漿配比和鉆進參數(shù)，有效避免了塌孔現(xiàn)象的發(fā)生，確保了施工的連續(xù)性；KR125則針對0~5米的復(fù)雜表層，快速破碎水泥硬化路面，處理沙卵石回填層和粉質(zhì)粘土層。?

The three rotary drilling rigs developed by TYSIM — KR220, KR165 and KR125 — have shown excellent performance. KR220 has strong torque output and drilling power. In the construction of the 7-17 meter clayey mud layer, it can easily overcome the resistance from the sticky soil, ensuring hole-forming efficiency and quality. KR165, with its precise control and stable operating performance, effectively prevents hole collapse in the construction of the 5-7 meter coarse sand layer by optimizing mud ratio and drilling parameters, ensuring continuous construction. KR125, targeting the complex surface layer of 0-5 meters, quickly breaks the cement-hardened road surface and handles the sand-gravel backfill layer and silty clay layer.

國際合作典范 技術(shù)與服務(wù)獲認可?

Model of Int'l Cooperation: Tech & Services Recognized

泰信機械參與伊斯蘭街下穿隧道項目，是中烏在基建領(lǐng)域國際合作的一個縮影。泰信機械不僅提供了先進的施工設(shè)備，還派遣了專業(yè)的技術(shù)團隊駐扎烏茲別克斯坦，與當?shù)厥┕F隊緊密協(xié)作，進行技術(shù)指導(dǎo)和設(shè)備維護。這種“設(shè)備+技術(shù)+服務(wù)”的模式，不僅保證了項目的施工進度和質(zhì)量，也為當?shù)嘏囵B(yǎng)了一批專業(yè)的施工技術(shù)人才，得到了烏茲別克斯坦政府和施工方的高度認可。這一合作不僅加快了伊斯蘭街下穿隧道項目的建設(shè)進程，也為烏茲別克斯坦未來的基礎(chǔ)設(shè)施建設(shè)提供了可借鑒的經(jīng)驗。

TYSIM's participation in the Islam Street Underpass Tunnel Project is a microcosm of international cooperation between China and Uzbekistan in infrastructure. TYSIM not only provided advanced construction equipment, but also sent a professional technical team to stay in Uzbekistan. They worked closely with the local construction team, offering technical guidance and equipment maintenance. This "equipment + technology + service" model not only ensured the project's construction progress and quality, but also trained a group of local professional construction technicians. It has been highly praised by the Uzbekistan government and the construction side. This cooperation has not only speed up the construction of the Islam Street Underpass Tunnel Project, but also provided useful experience for Uzbekistan's future infrastructure development.

深化中烏合作 共繪發(fā)展藍圖

Deepen China-Uzbek Cooperation, Co-shape Development Blueprint

目前，在泰信機械設(shè)備的助力下，伊斯蘭街下穿隧道項目的樁基施工已取得階段性成果，各項工作正按計劃有序推進。該項目的建成將極大改善當?shù)氐慕煌顩r，提升區(qū)域交通通行能力，為烏茲別克斯坦的經(jīng)濟社會發(fā)展注入新的活力。同時，這也將進一步推動中烏兩國在更多領(lǐng)域的合作，實現(xiàn)互利共贏。

Currently, with the help of TYSIM's equipment, the pile foundation construction of the Islam Street Underpass Tunnel Project has achieved phased results, and all work is progressing in an orderly manner as planned. The completion of the project will greatly improve local traffic conditions, enhance regional traffic capacity, and inject new vitality into Uzbekistan's economic and social development. At the same time, this will further promote cooperation between China and Uzbekistan in more fields, achieving mutual benefit and win-win results.
