Recently, the rotary drilling rig KR285C of TYSIM played a key role in the viaduct construction project in Chiang Rai, Thailand, showing excellent construction performance and contributing to the infrastructure construction in Thailand. The viaduct under construction is of great significance to the improvement of traffic in Chiang Rai, which will effectively improve the local transportation efficiency and promote regional economic development.
Challenging topography necessitates targeted construction techniques
In this construction, KR285C rotary drilling rig faced many challenges. Chiang Rai Province, as a mountainous province in northern Thailand, has complex and diverse terrain. The mountains here are an extension of the Nushan Mountains of the Yunnan-Guizhou Plateau in China, running through the entire territory from north to south. Large and small rivers crisscross, and the groundwater level is high. The geological conditions in the construction area are also relatively complex, which brings certain difficulties to the drilling operation. To meet these challenges, the construction team adopted targeted construction methods. The borehole diameter is designed to be 1000mm with drilling bucket with soil teeth. This drill bucket can adapt to different geological conditions and effectively improve drilling efficiency. When faced with complex geology and high groundwater levels, the construction team used a 6-meter casing under the puller to ensure the stability of the hole wall and prevent the occurrence of hole collapse accidents. After precise operation, the drilling depth finally reached 39.4 meters successfully.
A custom-designed chassis propels an efficient construction workflow
KR285C uses CAT chassis, which is like building a "robust skeleton" and "agile legs" for the equipment. It has been precisely designed and optimized, which not only enhances the equipment's pass ability in complex terrain, but also greatly improves its stability during construction. In the construction environment of Chiang Rai, where mountains and plains are intertwined and the ground is undulating. The chassis can easily cope with it, reducing the time and number of adjustments of equipment movement due to terrain restrictions. The precise steering and flexible movement characteristics of the chassis enable the drilling rig to quickly locate each drilling point without frequent large-scale site leveling, effectively saving construction preparation time. At the same time, stable chassis support ensures that the equipment remains stable during drilling operations, reducing operating errors and equipment losses caused by shaking. Thereby improving the success rate and efficiency of a single drilling operation.
Hard‑Core Capabilities Showcase the Fruits of International Collaboration
The KR285C rotary drilling rig of TYSIM has excellent performance, providing a strong guarantee for the smooth progress of the construction. The construction selected the appropriate configuration according to the actual needs. The intelligent computer monitoring system can also monitor the status of the drilling rig in real time and find and solve problems in time. In addition, key components such as the imported Rexroth motor reducer and the imported Kawasaki main pump have reliable performance and are relatively easy to maintain. The Chiang Rai Viaduct Construction Project in Thailand is a vivid practice of international cooperation in the field of infrastructure. The advanced equipment of TYSIM combined with the professional technology of the local construction team overcame the difficulties brought by the complex terrain. This not only reflects the competitiveness of China's machinery manufacturing technology in the international market but also injects new vitality into Thailand's infrastructure construction and promotes exchanges and cooperation between the two countries in the field of engineering construction. With the steady progress of the project. In the future, the Chiang Rai area will witness more convenient transportation, which will have a positive impact on the local residents' lives and economic development.
