Rock Drill

rock drill

A rock driller is a piece of equipment used for drilling the rocks. A rock drill is designed for heavier jobs such as bench and secondary drilling. 

there are so many reasons to drill rocks, such as soil nailing which means reinforcing the retaining walls to the rocky side by piles embedded into the rock, aslo this is used for different construction purposes like footing  lying and fixing equipment. and can also be used for drilling for smooth
blasting

The teeth of the rock driller have to be very sharp to cut the rocks without being damaged, and for that purpose, the alloy used for making these teeth consists of steel and  Powder of diamond. the driller arm is fitted to powering system which is carried on crawler or wheeled vehicle and often is powered by hydraulic system. There are some rock drills that can drill holes up to 6 meters deep

Petroleum Drilling

Drilling for oil  is one of the most important things in any economy, as oil means life for most industries. It can make a poor country rich in very short time.As the world is running out of this source of energy it is getting more value than ever. And we can notice the positive effect of oil extraction on Arabic  countries economy and other oil deposits around the world



The drilling operation requires high technique engineering and expert people  to get the job done in perfect way. It is a heavy industry needs  heavy equipment. On the scientific face it also very useful, geologists can identify the geologic reservoirs through the oil. It gets in almost every industry, for example, fuel for vehicles and factories and allot of things run on gas or oil, clothes made from chemical fibers , roads asphalt, and so many things that nobody can imagine


Though nothing have only good staff specially at dealing with the nature, it is very dangerous and carry a lot of risks during and after the extracting. The next video show animation explanation of the extraction process

Offshore Drilling

 petroleum drilling in water

Offshore petroleum drilling is drilling for oil under the ocean bed. And for that purpose  companies use special techniques and advanced platforms designed precisely to be steady on the water surface 

There are massive oil deposits under the ocean bed that make companies of oil extraction Obsessed to get it out.the first offshore oil drilling was in 1938 in the area of the gulf of Mexico. After that people know that something called offshore oil drilling and began to search for it around the world under the ocean floor. On the other hand, many people have an opposition of this kind of drilling due to its environmental bad effect and also the oil spills  on the coasts. 

The process of extraction varies a lot, depending on the depth and also on the suitable platform, floating or fixed or in case of best mobility it may be ships conducted to the underneath pipes. But every thing from the nature has a price,  offshore drilling operation is very dangerous and if something wrong happened the results can be catastrophic, besides it carry the danger of pollution. And for live example of that we can't forget the terrible  accident of the gulf of Mexico. the next video show an animation of how pipes driven in water

Pile Driver

Pile driver is one of the construction equipment used to install piles in soil to provide more support and stability, and also to form the core strength of a structure. The weight of the structure is transferred to the soil through the piles. 

This piling here is not common in all construction projects; it is only used in some cases like large structures and structures on poor soil. An example for poor soil is the soil of sea bed. In water construction piling is always used. Piles can be made of wood, steel ( H shaped or steel tubes) or reinforced concrete.

The pile driver use a heavy weight, lift it for big height and then releases it over the pile top. This impact force forces the pile to go into the soil. In case of concrete piles, they have to be especially reinforced to withstand the impact power. There are many types of pile driver developed with the time. These types such as

• Diesel Hammer Pile Driver.
• Hydraulic Hammer Pile Driver.
• Vibrator Pile Driver.

 

 And the sizes of these pile drivers vary from small to medium to large. near this equipment, some cautions are necessary like covering ears because of the noise, standing away from it while operating and other routine Maintenance must be done
