How To Prevent Track Slip of Rotary Drilling Rig?

Rotary drilling rig is an efficient construction machine, which is widely used in pile foundation construction, tunnel excavation and infrastructure construction. However, in the construction process, the track slip phenomenon of rotary drilling rig often brings no small trouble to the project progress and safety. It is very important to prevent track slip of rotary drilling rig to ensure construction efficiency and safety.

1. Pay attention to the influence of weather factors on track slip

When it rains or snows, the moisture content of the soil increases and the ground becomes slippery, which will lead to the adhesion of the track is reduced and it is easy to slip.

In extremely cold or high temperature environments, the hardness of the ground and the state of the soil will also change. At low temperatures, the soil surface may freeze, and the friction between the track and the ice is greatly reduced. In high temperatures, the ground may become soft and even muddy.

In the morning or at night, when the air is humid, a thin layer of dew may form on the surface of the soil, causing the ground to be slippery.

2. Be aware of the effects of topography and soil quality

In soft soil, soft sandy soil and other terrain, the track of rotary drilling rig is easy to fall into the soil, resulting in skid phenomenon.

When rotary drilling RIGS operate on slopes and uneven terrain, the risk of track slip is higher, especially when the machine is required to perform uphill or downhill work.

Hardened ground or hard rock formations can make it difficult for the track of a rotary drilling rig to gain sufficient friction during movement. Although hard surfaces are not prone to skidding, the track is prone to wear due to excessive friction.

3. Choose a more suitable construction environment

The operator of the rotary drilling rig should reasonably plan the operation path according to the geological conditions, weather and slope of the site. Try to avoid too steep or soft ground, choose a more flat, firm working area. If soft ground is encountered, the operator can consider using a gentle advance and retreat route to avoid intense rotation or rapid movement, thereby reducing the risk of slippage of the track.

On wet or soft ground, quick start or rapid movement will increase the probability of the track slipping. Operators should try to avoid sharp acceleration or sharp turns, control the speed of the rotary drilling rig, so that it can steadily move forward in a complex environment. Especially in uphill or muddy areas, you should start smoothly at low speed to avoid track slipping because you accelerate too fast.

During heavy rains, the carrying capacity of the soil is greatly reduced and the ground becomes very slippery. In order to avoid sliding of the track of the rotary drilling rig, the operation should be suspended and the equipment should be protected to avoid excessive ballast. In addition, before construction, you can consider strengthening the ground in advance, such as laying drainage pipes to reduce water accumulation and keep the ground dry.

Strong winds may cause the ground to dry and crack, serious dust, in this case, the friction of the track is easy to decrease, and the skid phenomenon increases. It is recommended to suspend the operation when the wind is too large, especially in the construction site in the open area, to avoid wind sand affecting the stability of the equipment.

4. Conclusion

The slippage of the track of rotary drilling rig will not only affect the operation efficiency, but also may bring security risks. By reasonably predicting the weather, optimizing the operation path, strengthening equipment maintenance and flexibly responding to different terrain and weather conditions, the phenomenon of track slip can be greatly reduced. Operators should stay alert during the operation, pay close attention to environmental changes, and adjust operation strategies reasonably to ensure that the rotary drilling rig can work smoothly and efficiently under various conditions.
