How Many Piles Can A Medium Or Small-sized Rotary Drilling Rig Drill in A Day

In foundation construction, understanding the pile formation efficiency of small and medium-sized rotary drilling RIGS is of vital importance for project schedule planning and cost control. However, the number of piles it can drill in a day is not a fixed value and is affected by multiple factors. Now let's talk to you in detail about the key influencing factors.

1.Geological conditions: When encountering soft soil layers such as clay and sandy soil, the drilling speed is fast, and 10 to 15 piles can be completed in a day. If encountering rock or pebble layers, not only is the efficiency low, but only 3 to 5 piles may be completed in a day.

2. Pile diameter and pile depth: When the pile diameter is small and the pile depth is shallow, the pile formation efficiency is high. For example, for piles with a diameter of 800mm and a depth of 15 meters, 8 to 12 can be driven in a day. However, for piles with a diameter of 1500mm and a depth of 30 meters, only 3 to 5 can be driven in a day.

3. Equipment performance: New equipment and well-maintained medium and small-sized rotary drilling RIGS have sufficient power, low failure rates, and naturally higher pile formation efficiency. Old equipment not only runs slowly but may also shut down due to malfunctions, affecting the daily number of piles formed.

4. Operator proficiency: Experienced operators can precisely control drilling parameters, make timely adjustments based on formation changes, and reduce ineffective operation time. It is quite normal for them to complete 2 to 3 more piles per day than novices.

5. Construction environment: The site is open and the transportation is convenient, which can reduce the time for equipment movement and waiting. If the site is narrow, transportation is inconvenient, or there is even cross-operation, it will all slow down the construction progress.

6. Auxiliary operation efficiency: The auxiliary links such as steel cage production and concrete pouring are closely coordinated, achieving seamless connection and effectively increasing the daily pile formation volume. Conversely, any delay in any link will affect the overall efficiency.

The number of piles formed by small and medium-sized rotary drilling RIGS in a day is restricted by multiple factors, among which geology, equipment, personnel and environment are all indispensable. Only by comprehensively considering these factors and optimizing the construction process can the efficiency of the equipment be fully exerted and the progress of the project be guaranteed.
