Precision in Hammer Drilling: Delving into the Process

Hammer drilling, a technique known for its meticulousness, unfolds within the range of 180 mm to 300 mm in diameter.

Initiating the Process:

At the crux of hammer drilling lies a sequence of precise steps, commencing with the selection of the drill's starting point or the designated well position. The orchestration of the drilling endeavor involves the strategic placement and calibration of the drilling apparatus, compressor, and the necessary drilling tools to align with the chosen drill point.

The Process Unfolds:

As the elements are harmoniously set in place, a stand pipe is introduced to facilitate the seamless progression of the procedure. Central to the technique is the introduction of the drill hammer, ingeniously positioned on a specialized leverage mechanism. The drill hammer's essential component, the bit crown, is meticulously fitted with industrial diamonds to ensure optimal efficiency.

Precision in Adaptation:

Tailored to the characteristics of the soil type, distinct bit crowns come into play, reflecting the versatility of the approach. The pivotal moment arrives when the compressor, tethered to the drilling apparatus via a hose, is initiated. This catalyzes the air-driven force, with power ratings varying from 16 to 26 bar, contingent upon the soil composition.

Methodical Progression:

The orchestration of mechanical elements, from the rotation of the leverage and piping to the transmission of compressed air to the hole bottom, epitomizes the precision inherent in hammer drilling. Notably, the bit crowns incorporate rinse ports, facilitating the expeditious evacuation of the borehole's cuttings.

Ensuring Efficiency:

The annular space between the leverage and piping plays a pivotal role in conveying the excavated drill cuttings to the surface, exemplifying the meticulous nature of the operation.

Simultaneous Mastery:

This drilling technique intertwines the prowess of hammer drilling at the leverage with the hydraulic rotary table mechanism at the piping, orchestrating a harmonious dual effort. The procedure unfolds in a synchronized manner, culminating when both the piping and leverage have been fully extended.

Advancing Deeper:

Progression is achieved through a calculated series of actions: disassembling the hammer-attached leverage, securing a fresh leverage and piping, and repeating the cycle. This iterative approach continues until the desired drilling depth is attained.

Strategic Insights:

The very act of drilling unravels more than just layers of earth; it unveils the identity of water-bearing formations, a crucial juncture that informs the placement of the impending filter pipe, central to the well's functionality.

The Culmination:

Upon reaching the predetermined drilling depth, the meticulous operation shifts towards its conclusion. The disengagement of the leverage, to which the drill hammer is affixed, marks the culmination of the process, characterized by its precision, attention to detail, and unwavering commitment to quality outcomes.
