The customized construction method for complex landforms breaks the deadlock Taixin Machinery KR300C contributes to the construction of the Chiang Rai Elevated Bridge in Thailand

Recently, the KR300C rotary drilling rig with Caterpillar undercarriage, developed by Tysim Piling Equipment Co., Ltd.(hereinafter referred to as "Tysim"), has played a pivotal role in the viaduct construction project in Chiang Rai, Thailand, demonstrating exceptional construction performance and contributing significantly to Thailand's infrastructure development. This viaduct project holds great importance for improving transportation in the Chiang Rai region. It will effectively enhance local transportation efficiency and boost regional economic development.

During this construction project, the KR300C rotary drilling rig faced numerous challenges. Chiang Rai Province, located in the northern mountainous region of Thailand, has a complex and diverse terrain. The mountainous areas here are an extension of the Nu Shan Mountain Range in China's Yunnan and Guizhou provinces, running from north to south throughout the province. In the plain areas such as Mae Sai and Mae Sot, numerous rivers crisscross and the groundwater level is relatively high. The geological conditions in the construction area are also rather complex, posing certain difficulties for pile driving operations. To address these challenges, the Tysim Thailand construction team adopted targeted construction methods. The diameter of the pile holes was designed to be 1 meter, and a double-bottom bucket with cutting teeth was used. This type of drilling tool can adapt to different geological conditions and effectively improve drilling efficiency. When encountering complex geological conditions and a high groundwater level, the construction team used a driving and extracting machine to install a 6-meter casing to ensure the stability of the hole wall and prevent hole collapse accidents. Through precise operation, the final drilling depth successfully reached 39.4 meters.

The Tysim KR300C is equipped with a customized Caterpillar rotary drilling rig chassis, which is like creating a "sturdy skeleton" and "robust body" for the equipment. This chassis, after precise design and optimization, not only enhances the equipment's passability in complex terrains but also significantly improves its stability during construction thanks to the Caterpillar chassis. In the Chiang Rai area where mountains and plains alternate and the ground is uneven, the Tysim drilling rig can handle the situation with ease, reducing the time and frequency of equipment movement and adjustment due to terrain restrictions. The precise steering and flexible movement characteristics of the Caterpillar chassis enable the drilling rig to quickly position itself at various drilling points without the need for extensive site leveling, effectively saving construction preparation time. At the same time, the stable chassis support ensures that the equipment remains steady during pile driving operations, reducing operational errors and equipment wear caused by shaking, thereby increasing the success rate and efficiency of each pile driving operation.

Tysim's KR300C rotary drilling rig, built on a Caterpillar undercarriage, delivers outstanding performance and provides robust assurance for smooth construction operations. For this project, the optimal configuration was selected based on actual requirements. Its intelligent computer monitoring system enables real-time tracking of equipment status, allowing prompt identification and resolution of issues.Key components such as the original Rexroth hydraulic motor reducer and imported Kawasaki main pump ensure reliable performance with relatively straightforward maintenance.The Chiang Rai Viaduct Construction Project stands as a vivid example of international collaboration in infrastructure development. By combining Tyism's advanced piling equipment with the specialized construction techniques of its Tysim Thailand , the project successfully overcame challenges posed by complex terrain.This achievement not only demonstrates the global competitiveness of China's piling machinery manufacturing technology but also injects new vitality into Thailand's infrastructure development. It further enhances engineering cooperation and knowledge exchange between the two nations.As the project progresses steadily, Chiang Rai will benefit from improved transportation networks, bringing positive impacts to local communities and economic growth.
