Recently, the Yuchai YCR280 rotary drilling rig has been involved in the bridge pile foundation construction of the Shaanxi Qu-Tai Expressway Expansion Project. The equipment operates well and efficiently, winning high praise from customers.

In the current era of rapidly advancing trains, transportation infrastructure has flourished. As an important component of transportation infrastructure, reinforced concrete bridges are increasingly becoming a focus in transportation infrastructure construction. Bridge pile foundations are one of the very important components of reinforced concrete bridge construction, and their load-bearing capacity has a direct impact on the safety of bridge use. With the continuous updating and development of drilling rig technology, rotary drilling rigs, as the main hole-forming equipment, have been widely used in engineering construction such as bridge pile foundations. The Yuchai YCR280 rotary drilling rig participating in the Qu-Tai Expressway Expansion Project, which is the reconstruction and expansion project of the Qujiang to Taiyigong section with a total route length of 18.53 kilometers, is of great significance for effectively alleviating traffic congestion in the southern area of Xi'an, substantially improving the traffic service level in the north-south direction of Shaanxi Province, and ensuring the convenience and smooth flow of the national highway corridor.

The Yuchai YCR280 rotary drilling rig is equipped with a Cummins engine, featuring high work efficiency and strong power, and can quickly and accurately complete pile foundation construction, thereby greatly shortening the construction period. The equipment also adopts professional drill pipes and drill bits. The drill pipes are light in weight and meet the on-site requirements for drilling depth and diameter. The drill bits use independent intellectual property rights and have been continuously optimized and improved by the R&D team, making the precision and effect during construction even better. The Yuchai YCR280 rotary drilling rig also features flexibility and adaptability. The rig can adapt to different sites and environments, such as bucket transfer and repositioning, free bridge crossing, and hydraulic self-locking on slope tops, effectively ensuring construction site safety and construction efficiency.

The strata at the construction site of the Yuchai YCR280 rotary drilling rig are mainly clay layers and strongly weathered mudstone layers. The construction pile diameter is 1.6 meters, the hole-forming depth is 45 meters, and the hole-forming time is about 2 hours. After multiple sampling inspections by the National Expressway Quality Inspection Center, the hole-forming quality of the Yuchai YCR280 rotary drilling rig has been recognized. Customers have highly praised the equipment's high efficiency, stability, and safety.
