Pile Foundation
DRILLING COMPANY
DRILLING COMPANY
SEVASO Group, started with its experience in soil techniques, ground survey, and construction works, especially in geotechnical matters; It offers project services in piles foundation, Anchor, Soil nails, Jet Grout, and Shout Great, works.
We add to our career and working experience in pile works by cooperating with great partners in Iraq to deliver with high efficiency to multiple projects within Baghdad and the surrounding Area.
Our company is taking firm steps towards the coming years with the latest technology of the 21st century. This success is undoubtedly the work of a young, dynamic technical staff who are focused on the same goals with a principled and progressive method.
Our company, which has sufficient knowledge and experience in the construction of Cast-in-Situ Reinforced Concrete Piles (Bore Piles), intersecting piles, Anchor, Injection, Soil nails, Jet Grout, and Shout Grinding, continues its work domestically and abroad.
A pile is a long cylinder of a strong material such as concrete that is pushed into the ground to act as a steady support for structures built on top of it.
We have rigs that are capable of forming piles 600 to 1200mm in diameter and to a depth of up to 60.0 meters. The piles are constructed using self-inserting hydraulic rigs 30 to 70T the lighter variants being particularly well suited to small sites meaning that most sites are accessible with our equipment. Contact us to get detailed information about our company, which continues its activities in Iraq, we are ready to participate in any project all over Iraq.
Pile foundations are used in the following situations:
- When there is a layer of weak soil at the surface. This layer cannot support the weight of the building, so the loads of the building have to bypass this layer and be transferred to the layer of stronger soil or rock below the weak layer.
- When a building has hefty, concentrated loads, such as in a high-rise structure, bridge, or water tank.
Pile foundations are capable of taking higher loads than spread footings.
There are two fundamental types of pile foundations (based on structural behavior), each of which works in its way.
End Bearing Piles
In end-bearing piles, the bottom end of the pile rests on a layer of especially strong soil or rock. The load of the building is transferred through the pile onto the strong layer. In a sense, this pile acts like a column. The key principle is that the bottom end rests on the surface which is the intersection of a weak and strong layer. The load therefore bypasses the weak layer and is safely transferred to the strong layer.
Friction Piles
Friction piles work on a different principle. The pile transfers the load of the building to the soil across the full height of the pile, by friction. In other words, the entire surface of the pile, which is cylindrical, works to transfer the forces to the soil.
Rotary Auger Bored Piling
The rotary auger bored piling technique utilizes a short flight auger attached to the Kelly bar of the piling rig and creates the pile bore by removing the soil in short sections, using augers approximately 1 to 3 meters long, dependent upon the hole size, until the design depth has been reached. In non-cohesive ground conditions, such as made ground and or granular layers, a steel temporary casing is inserted and sealed into the top of the clay to prevent soil collapse or groundwater inflow. This casing is either screwed in using the rig or vibrated into place using an ancillary service crane and specialist vibrator equipment. A reinforcing cage is then installed into the open bore and concrete is placed in via a hopper and or delivery tube.
