Submarine hammer drilling, often referred to as underwater percussion drilling, is an advanced technique utilized primarily in marine construction and resource exploration. This method combines the principles of traditional drilling with hydraulic and pneumatic operations, enabling the effective penetration of hard substrates beneath the sea floor. In this article, we will explore the processes, equipment, advantages, and applications of submarine hammer drilling.

The primary function of a drainage pump is to collect and remove water from a specified area. Most commonly used in basements, crawl spaces, and construction sites, these pumps are equipped with a float switch that activates the pump when water reaches a certain level. Once the water is detected, the pump will turn on, drawing the water into its casing and expelling it through a discharge pipe to a designated drainage area. This process continues until the water level drops below the float switch, at which point the pump turns off.
