How to Properly Transport, Store and Use Drill Rods?

Table of Contents

Many factors affect the service life of rock drilling tools, and they are also very complex. In addition to internal factors such as steel type and process, external factors such as corrosion, bending, and bumping during transportation and storage also directly or indirectly affect the service life of rock drilling tools. Therefore, to maximize the service life of rock drilling tools, in addition to choosing high-quality rock drilling tools, prevention should be taken during transportation, storage, and use. Especially the drill rod, it is a slender rod and more likely to cause damage. How to reasonably carry out transport, storage, and use the drill rod is particularly important for enterprises.

Types and selection of drill rods

There are many varieties of drill rods, including integral drill rods, tapered drill rods, threaded extension rods, etc. When choosing drill rods, it should be selected according to actual needs, such as project type, efficiency requirements, economy, and other factors.

Precautions for transporting drill rods

Civilized loading and unloading

In the process of loading and unloading, the goods are easy to be subjected to violent handling. Rock drilling tools are steel products, and unprofessional loading and unloading personnel will take it for granted that this loading and unloading method will not cause damage to them. On the contrary, the cyclic stress is very sensitive to the surface damage of the drill rod, which will directly lead to sudden fracture, and the formation of fatigue failure, so civilized loading and is necessary.

Double packing

To effectively prevent bending, bumping, and water hole blockage, double-layer packaging should be used according to regulations, namely, the inner layer is softly packaged and the rock drilling tools should be separated by plastics. In addition, plastic sleeves and water hole plugs should be inserted at both ends of the rod.

Prevent rain and water immersion

The material of the drill rod is brazing steel. After being drenched in rain or water, the drill rod is prone to rust due to the action of moisture and oxygen in the atmosphere, shortening the service life. Therefore, it is necessary to strictly prevent rain and water immersion during transportation.

Security issues

During transportation, it should be ensured that the drill rods are well fixed to avoid sliding or rolling. Meanwhile, longer drill rods should take anti-tipping measures to ensure transportation safety.

Transportation method

Longer drill rods should be transported appropriately, such as using special brackets or lifting equipment, to ensure stability and safety during transportation.

Precautions for storing drill rods

Classified storage

Drill rods with damaged packaging or damp, bent, bruised, or blocked water holes should be inspected and repaired one by one and then repackaged and stored separately. Drill rods that have not been wetted and are well packaged should be classified and placed on the rock drill tools rack after acceptance.

Storage location

Drill rods should be stored in a dry, well-ventilated, and dust-free room, avoiding the sunshine, rain, and humid environment.

Moisture-proof measures

For drill rods stored for a long time, appropriate moisture-proof measures should be taken, such as checking the humidity regularly and placing desiccant to avoid rusting and damage.

Regular maintenance

Regularly inspect drill rods and promptly dispose of those with bends, deformations, cracks, etc., while maintenance supplies such as anti-rust oil should be applied regularly.

Marking records

It is also very essential to label and record the drill rod well. Each drill rod should be clearly labeled with its model number, specifications, production date, and other information and recorded. It helps us quickly find the right drill rod when needed and understand each drill rod‘s usage and maintenance history.

Precautions for using drill rods

Preparation

Before use, check whether the drill rod is intact and confirm that there are no problems before use. At the same time, other required tools and safety equipment should be prepared. For example, When leading and sending drill rods, pay attention to prevent bending, rust, injury, and blocking. Before drilling, we should check the wear state of the rock drill shank adapter, the operation of the rock drilling equipment, and the overall condition of the drill rod.

Correct selection of rock drilling tools and equipment

①The length of the drill rod should meet the depth required, and should not be too long.

②The connection status of the drill rod and the drill bit should meet the requirements, and the dimensional accuracy and contact conditions should be good.

③Choose drill bits with fast drilling speed and long service life. Its diameter should meet the requirements of the drilling hole diameter, and should not be too large.

④ The hydraulic rock drilling equipment with moderate and adjustable impact power, good stress waveform, and anti-jamming and automatic feeding facilities is preferred.

In use

According to different operating requirements, use the correct method to avoid damaging the drill rod or affecting the quality of the project. For example, use smaller impact energy to open the hole and appropriately adjust the shaft thrust, wind pressure, and water volume. Keep the rock drill and the rock drilling tools consistent with the axis of the drilling hole at any time, so that the chip removal is unobstructed and the drill rod rotates flexibly.

During the drilling process, the operator needs to keep the drill rod in alignment with the ground to prevent unnecessary wear from side forces. Additionally, the drill rod should avoid excessive wear and replace the worn parts in time to ensure its overall performance and service life.

Operation process

Familiar with the operation process, follow the operation specifications for construction, and avoid accidents caused by improper operation. For example, when drilling, choose the appropriate rock drill bit and drilling speed according to the needs, and keep the drilling rig stable and safe.

After use

①Repair and replace blunt drill bits and expired drill bits in time, and it is forbidden to use blunt drill bits.

②Use the special tool to discharge the rock drilling tools. Do not use a hand hammer to remove the drill bit.

③The drill rod should be wiped dry, oiled, and placed flat on the special drill rod holder immediately after use.

④ Drill rods that have not been used for a long time should be properly stored. When storing, it’s important to select a dry and ventilated location, avoiding direct sunlight and humid environments. Additionally, avoid exposing the drill rod to corrosive substances or chemicals to prevent damage.

Conclusion

In short, reasonable transportation, storage, and use of drill rods are critical factors to ensure project quality and improve construction efficiency. During the construction process, engineering construction personnel should fully understand the characteristics and usage methods of drill rods and make selections and operations based on actual conditions to ensure the smooth progress of project construction. At the same time, every aspect of the transportation, storage, and use of drill rods must be strictly abided by relevant regulations and standards to ensure that project materials and equipment are properly handled and lay a solid foundation for the quality and safety of the entire project construction.
