A 20mm drill rod typically refers to a cylindrical tool made of high-strength steel, designed for use in drilling operations. Its 20mm diameter strikes a balance between robustness and manageability, allowing it to penetrate materials while maintaining sufficient structural integrity. The rod can be produced in various lengths, which can be tailored to the specific requirements of a drilling project. Additionally, many manufacturers offer drill rods with various coatings or treatments to enhance wear resistance and durability, making them suitable for use in harsh environments.
The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.
One of the notable advantages of submarine hammer drilling is its efficiency in penetrating tough materials. Traditional drilling methods may struggle with hard rock formations, often resulting in slower progress and increased operational costs. Hammer drilling wears less on the drill bit, ultimately reducing the frequency of replacements and downtime.

When the pile driver is working, the pile driver should be reliably grounded to reduce the risk of personal electric shock.
The reason:
The suction pipe is not filled with water
Blocked suction line or inadequate valve opening
The inlet pipe of the pump, the meter or the stuffing box are serious
