复杂地质轻松克服，施工效率提升

Complex Geology Easily Overcome, Construction Efficiency Up

该项目施工区域的地质条件复杂，给桩基施工带来了巨大挑战。从地表往下，0~1米是水泥硬化路面与沙卵石回填层，坚硬且结构松散，对设备的入岩和钻进能力是极大考验；1~5米为粉质粘土层，粘性大，易造成钻头堵塞；5~7米的粗砂层，稳定性差，极易发生塌孔；7~28米的粘泥层，质地粘稠，钻进阻力大，效率难以保证。

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.

泰信机械研制的KR220、KR165、KR125三款旋挖钻机展现出了卓越的性能。KR220 拥有强大的扭矩输出和钻进动力，在7~17米的粘泥层施工中，能够轻松克服粘稠土壤带来的阻力，保证成孔效率和质量；KR165则凭借其精准的控制和稳定的作业性能，在5~7米的粗砂层施工中，通过优化泥浆配比和钻进参数，有效避免了塌孔现象的发生，确保了施工的连续性；KR125则针对0~5米的复杂表层，快速破碎水泥硬化路面，处理沙卵石回填层和粉质粘土层。

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.

深化中乌合作 共绘发展蓝图

Deepen China-Uzbek Cooperation, Co-shape Development Blueprint

目前，在泰信机械设备的助力下，伊斯兰街下穿隧道项目的桩基施工已取得阶段性成果，各项工作正按计划有序推进。该项目的建成将极大改善当地的交通状况，提升区域交通通行能力，为乌兹别克斯坦的经济社会发展注入新的活力。同时，这也将进一步推动中乌两国在更多领域的合作，实现互利共赢。

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.
