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.
Complex Geology Easily Overcome, Construction Efficiency Up
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.
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.
Model of Int'l Cooperation: Tech & Services Recognized
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.
Deepen China-Uzbek Cooperation, Co-shape Development Blueprint
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.
