Cutterhead Dredging

 

In marine construction, the creation of deep foundations is often necessary to ensure that structures are properly supported. This is especially the case in areas where the surface level of the floor of a lake or an ocean isn’t strong enough to provide support to heavy loads. Pile driving is used as a way to engineer a deep foundation. Piles are driven several feet below the surface of the floor or ground to help create rock-like, sturdy platforms - environmental dredging.

The answer to dealing with pile obstructions varies based on the depth of the obstruction. The unanticipated motion of piles is another indication of a problem that needs to be resolved before work continues. Where the blow depends is far lower than anticipated, evaluate the soil borings. You will need to do restrike testing in the case of decreased soil resistance. This requires establishing the setup factor and driving to a lower capability. The variety of blows needed to drive the pile to the required depth is calculated upfront. If it's taking many more blows to drive the pile than planned, there is an issue with the soil and/or the driving system. In addition to sheet piling, structural pipe piling is often used in areas of marine construction. Pipe piling creates a tremendous amount of frictional load resistance in deep foundations and boasts excellent point bearing capabilities - cutterhead dredging.

Sheet piles are often made of steel, concrete, or timber. Composite sheet piles are made of a mixture of concrete and steel. This type of pile can be used to create capped columns or to build wall-like foundations underground. Sheet piles either have to be forcefully driven into the ground, or are driven into holes that are drilled before their placement. The depth of a foundation created using the driving of sheet piles is determined by how far below it takes to reach stable, solid ground.
