Construction Engineering Borehole Pile Rotary Drilling Rig Kelly Bar for Soil Rock Drilling with High Precision

Product Overview

The Construction Engineering Borehole Pile Rotary Drilling Rig Kelly Bar is a state - of - the - art equipment part designed specifically for soil and rock drilling in construction engineering projects. This kelly bar is brand new, ensuring high - quality performance and reliability from the very start. It is an essential component for rotary drilling rigs, which are widely used in borehole pile construction.

Design and Structure

• Robust Build: The kelly bar is constructed with high - strength steel materials. This choice of material not only provides excellent durability but also allows it to withstand the high - stress environment during drilling operations. The steel is carefully heat - treated to enhance its hardness and toughness, making it resistant to wear and tear, even when drilling through hard rock layers.
• Precision Design: The design of the kelly bar features a precise helical structure. This helical design helps in efficient torque transmission from the drilling rig to the drill bit. It ensures that the drill bit rotates smoothly and steadily, enabling accurate drilling with high precision. The pitch of the helix is carefully calculated to optimize the drilling speed and the amount of soil or rock removed per rotation.
• Modular Design: It adopts a modular design, which means different sections of the kelly bar can be easily assembled and disassembled. This modularity allows for easy transportation and on - site adjustment according to the specific requirements of the drilling project. For example, if a deeper borehole needs to be drilled, additional sections can be added to increase the length of the kelly bar.

Functionality

• Soil and Rock Drilling: This kelly bar is suitable for both soil and rock drilling. In soil drilling, it can quickly penetrate through various types of soil, such as clay, sand, and silt. When it comes to rock drilling, its high - strength structure and efficient torque transmission enable it to break through hard rock formations, including limestone, granite, and sandstone.
• High - Precision Drilling: Thanks to its precise design and stable torque transmission, the kelly bar can achieve high - precision drilling. It can maintain a straight and accurate borehole, which is crucial for the stability and integrity of the borehole pile. This high precision reduces the need for re - drilling and ensures that the construction project can proceed smoothly.
• Efficient Material Removal: The helical structure of the kelly bar facilitates efficient removal of the drilled soil or rock. As the drill bit rotates, the helix helps to lift the cuttings out of the borehole, preventing them from accumulating at the bottom and causing blockages. This efficient material removal improves the overall drilling efficiency and reduces the wear on the drill bit.

Compatibility

• Rotary Drilling Rigs: The kelly bar is designed to be compatible with a wide range of rotary drilling rigs. It can be easily installed on different models of rotary drilling rigs, making it a versatile choice for construction companies. Whether it is a small - scale drilling rig for residential projects or a large - scale rig for commercial construction, this kelly bar can provide reliable performance.
• Drill Bits: It is also compatible with various types of drill bits. Different drill bits are suitable for different drilling conditions, and the kelly bar can work seamlessly with them. For example, it can be paired with a drag bit for soft soil drilling or a roller cone bit for hard rock drilling.

Maintenance and Service

• Easy Maintenance: The modular design of the kelly bar makes it easy to maintain. Each section can be inspected and replaced separately if necessary. The surface of the kelly bar is coated with an anti - corrosion layer, which protects it from rust and corrosion, especially in harsh outdoor environments.
• Technical Support: In case of any technical problems or questions, users can rely on professional technical support. The manufacturer has a team of experienced engineers who can provide timely assistance, including installation guidance, troubleshooting, and maintenance advice.

The Construction Engineering Borehole Pile Rotary Drilling Rig Kelly Bar is a high - quality, reliable, and efficient equipment part that offers excellent performance in soil and rock drilling. Its advanced design, functionality, compatibility, and ease of maintenance make it an ideal choice for construction engineering projects around the world.
