Best Pile Driving from pmgsocial media's blog

Pile driving is a critical part of the construction process. Vertical columns made of various materials (wood, concrete, steel, or a combination) are driven into un-excavated soil. The piles are a type of deep foundation used to hold up large structures – often bridges. In this article we discuss pile driving basics, the common problems encountered, and potential solutions.Early pile driving was done by hand. The energy required to drive a pile was created by the weight of the ram falling through the gravity field. In the twentieth century, greater driving force was achieved by using air- or steam-powered machines to accelerate the ram’s downward action. Many of today’s pile driving hammers are powered by diesel or hydraulic systems - pile driving.

At a high level, a pile driving system has four main parts: lead, hammer cushion, helmet, and pile cushion. Each part has a role in transferring energy to the pile which in turn impacts hammer performance. The pile driver lead is a supporting framework that guides the pile and hammer. They are categorized by how they attach to the pile driver hanging, fixed, or swinging. Leads keep the piling and hammer aligned. A hammer cushion, typically made of man-made materials, is placed between the striker plate and helmet - Harbor Pile Driving.

The design of a pile foundation is highly dependent on the soil the piles are driven into. Other factors include the material of the piles, the expected load, and the level of use anticipated. Keep in mind that driving the piles alters how the soil around it will behave. As well, soil particularly in a large area can vary greatly. Determining the right design is difficult. The planning process must include extensive and careful soil testing. Testing and evaluation should continue during construction.

Piles driving into the soil much deeper than original estimates may be due to lower soil resistance than anticipated. Or increased driving system performance. A restrike test is needed to determine changes in the soil strength. A structural engineer will determine if changes in the driving system or pile depth are required.
