Sheet pile walls are constructed by driving prefabricated sections into the ground. Soil conditions may allow for the sections to be vibrated into ground instead of it being hammer driven. The full wall is formed by connecting the joints of adjacent sheet pile sections in sequential installation. Sheet pile walls provide structural resistance by utilizing the full section. Steel sheet piles are most commonly used in deep excavations, although reinforced concrete sheet piles have also being used successfully.
Steel sheet piling is the most common because of several advantages over other materials:
1. Provides high resistance to driving stresses.
2. Light weight
3. Can be reused on several projects.
4. Long service life above or below water with modest protection.
5. Easy to adapt the pile length by either welding or bolting
6. Joints are less apt to deform during driving.
Sheet pile walls are constructed by:
1. Laying out a sequence of sheet pile sections, and ensuring that sheet piles will interlock.
2. Driving (or vibrating) the individual sheet piles to the desired depth.
3. Driving the second sheet pile with the interlocks between the first sheet pile and second "locked"
4. Repeating steps 2 & 3 until the wall perimeter is completed
5. Use connector elements when more complex shapes are used.
Deepwell Corporation was incorporated in 1972 after acquiring all Plants, Equipment and stores of the U.S. Firm M/s Harold T.Smith which winded up its drilling business in Pakistan. Since its inception Deepwell has been continuously updating and replenishing its equipment and services to meet the modern demands of the industry through Research and Development.
