The core of selecting a rotary drilling rig is to match the geological characteristics. The hardness, permeability, and wear resistance of the four types of soil layers—clay, sand, gravel, and hard rock—differ significantly, directly determining the selection of the rig's power, torque, and drill bi Read More

The configuration upgrade of rotary drilling rigs needs to take into account practicality, economy, and scene adaptability. Blind selection can easily lead to cost waste, and precise selection of core functions is necessary to achieve "adding money is adding value". Based on the current construction Read More

The renovation of old urban areas is the core link of urban renewal, and pile foundation engineering serves as the foundation support for the renovation project. Due to factors such as dense existing buildings, narrow roads, and complex pipelines in the urban area, the construction space is extremel Read More

As the core equipment of infrastructure construction, the daily maintenance of rotary drilling rig is the key to extending the service life of the equipment, reducing the failure rate, and ensuring the continuity of construction. Compared to maintenance and repair after a malfunction, scientific and Read More

The core of selecting a rotary drilling rig is to adapt to geological conditions. The four typical geological conditions of clay, sand, gravel, and hard rock have significant differences. Improper equipment selection can easily lead to low construction efficiency, increased equipment wear, and e Read More
