Why Is A Casing Used for Rotary Drilling RIGS in Rural Construction

When conducting construction in rural areas, the operation of rotary drilling RIGS may seem simple, but in fact, there are hidden dangers, especially the use of the casing is indispensable. Now let me tell you why rotary drilling RIGS need to use casings when working in rural areas.

1. Stabilize the hole wall: The geological conditions in rural areas are complex, and there are often loose soil layers and sand. The casing is like a "safety guard", slewing around the borehole to prevent the borehole wall from collapsing, ensure the stability of the borehole and avoid all previous efforts being wasted.

2. Isolate debris: It is inevitable that there will be stones, tree roots and other debris in the construction area. The casing can separate the borehole from the outside world, preventing debris from falling into the borehole, ensuring the borehole is clean and not affecting subsequent operations.

3. Control the pile position: Precise construction is the key. The casing can fix the drilling position, prevent the drilling rig from shifting, ensure that the pile foundation accurately "lands", guarantee the project quality and prevent deviations.

4. Prevent water seepage: If the groundwater level is high, water is prone to seep into the holes. The casing can form a closed space to prevent the influx of groundwater, keep the hole dry, facilitate concrete pouring, and ensure the strength of the pile foundation.

5. Protect the drilling rig: During the drilling process, the collapse of the hole wall may cause the drill to get stuck and damage the drilling rig. The casing maintains the stability of the hole wall, reduces the direct contact between the drilling rig and the unstable soil layer, and lowers the risk of equipment damage.

6. Convenient for construction: With the casing, the drilling rig positions more quickly, and the depth and verticality of the borehole are better controlled. Moreover, it can also guide the smooth pouring of concrete and improve the construction efficiency.

In conclusion, in rural construction with rotary drilling RIGS, although the casing may seem insignificant, it plays a crucial role in stabilizing the hole wall, ensuring the accuracy of the pile position, and protecting the equipment. It is like a "behind-the-scenes hero" that guards silently. Without it, the construction not only has low efficiency but may also cause various problems, affecting the quality and safety of the project.
