Due to continuous water erosion and geological changes, the slopes of certain sections of the Beijing-Hangzhou Grand Canal collapsed and loosened, posing a serious threat to shipping safety. The bank protection project became extremely urgent. However, the narrow and rugged construction site, coupled with the requirement of uninterrupted shipping during construction, rendered conventional equipment inadequate. Standing out with its outstanding performance, the Tysim KR150 drilling rig took on the crucial task of reinforcing the canal banks.
I. Facing Complex Construction Challenges
The construction site was narrow and uneven. Leveraging the advantages of its crawler walking system, the KR150 drilling rig maneuvered through the confined areas with precise steering and stable movement. Thanks to its design with low ground pressure, it effectively prevented sinking on muddy ground, ensuring stable positioning at each work site.
The project involved a complex geological formation, alternating between soft sandy soil and hard weathered rock layers. With a powerful torque of 150 kN·m, the KR150 drilling rig could quickly penetrate sandy soil and break through rock layers. Its intelligent control system monitored parameters in real-time and issued immediate warnings when geological changes occurred. For example, during construction in sandy soil sections, the system alerted the operators of potential hole collapse risks. They promptly reduced the drilling speed and strengthened mud support, safeguarding the quality of bored piles and construction safety.
During construction, the KR150 drilling rig collaborated seamlessly with steel cage hoisting and concrete pouring equipment. Once the drilling was completed, all equipment coordinated smoothly, significantly shortening the construction time for each bored pile.
II. Remarkable Achievements Highlighting Strength
Compared with traditional drilling rigs, the KR150 drilling rig increased construction efficiency by 30%, successfully overcoming the tight schedule and minimizing disruptions to canal shipping. These achievements earned high praise from the project management and relevant authorities.
In terms of bored pile quality, the verticality deviation was controlled within 0.5%, the hole diameter error was less than 5mm, and all piles met the integrity standards, firmly securing the canal banks.
III. Customer Recognition and Future Prospects
The project manager commended, “The KR150 drilling rig exceeded our expectations. It balanced efficiency and quality under complex conditions. For similar projects in the future, Tysim equipment will be our top choice!” The success of this project confirms the formidable strength of the Tysim KR150 drilling rig. In the future, Tysim Machinery will continue to innovate, committed to providing higher-quality equipment and services for construction projects worldwide.
