Delmag on Driving Sheet Piles

It may seem odd on this site, but we present the Delmag Guide to Driving Sheet Piles, which Delmag (a one-time competitor of Vulcan's) put out many years ago. It's a nice and comprehensive guide to the subject for impact hammers; it's a subject that's not always well understood. Diesel hammers (in Europe at least, … Continue reading Delmag on Driving Sheet Piles

Sixty Years of Vulcan in Chattanooga

In the midst of all that's going on these days, one anniversary (for this site at least) doesn't need to pass unmentioned: this month sixty years ago, Vulcan moved its operation from Chicago to Chattanooga, after 108 years in the "Windy City." Everything around the operation went according to plan, from the plant construction to … Continue reading Sixty Years of Vulcan in Chattanooga

Driving Concrete Piles Wild

Driving piles wild, i.e., without any leader of any kind, is something that takes a great deal of skill and forethought by the contractor. Like piles driven with a stub leader, it is necessary at least to use some kind of template to insure that the pile is on location and in alignment, and also … Continue reading Driving Concrete Piles Wild

Using a Vulcan #2 for Residential Piling

Most residences do not require pile foundations, but some do, generally because of the combination of the size of the house and the geotechincal stratigraphy (read soft.) In Vulcan's history this is generally associated with the New Orleans area, but recently a Vulcan #2 was used to drive residential piling in Connecticut. The whole post … Continue reading Using a Vulcan #2 for Residential Piling

Leaving the Derrick Barge Behind

Above is a photo of one of Ingram Construction's barges in the wake (literally) of the crew boat carrying Vulcan's representative (probably Jess Perry) away after a field service trip. Vulcan developed its field service capabilities mostly in response to its customers in the Gulf of Mexico and elsewhere, and that frequently entailed long field … Continue reading Leaving the Derrick Barge Behind

Colonnades Beach Hotel

One of the pleasures of having an office in West Palm Beach was the ability to take in the pleasures of a resort area like South Florida. One of those more pleasurable places was the Colonnades Beach Hotel on Singer Island; the photo above of the entrance dates from October 1966. I'm not sure how … Continue reading Colonnades Beach Hotel

Pile Driving Part III: Installation Equipment — Pile Buck Magazine

View Part II of this article here. Over time, the technology for pile installation has led to the development of hammers that are both larger and faster. From rams that were raised by humans or horses to steam, air, and hydraulic hammers to double acting hammers, this equipment is an essential part of any construction… via … Continue reading Pile Driving Part III: Installation Equipment — Pile Buck Magazine

No, the Cut-In Height Didn’t Cause the “Downfall” of the Air Hammers

There's an urban legend going around social media these days that states that the "demise" (which is hardly true since they're still in use) of air hammers is due to the fact that the valve admits air to the cylinder before impact, thus slowing down the ram.  This legend has it that this was detected … Continue reading No, the Cut-In Height Didn’t Cause the “Downfall” of the Air Hammers

OTC 5395 Revisited: Analysis of Cushioned Pile Hammers

This is a new paper to update and expand on part of the first technical paper presented by a Vulcan employee: the paper "A Proposal for a Simplified Model for the Determination of Dynamic Loads and Stresses During Pile Driving," originally presented at the 1987 Offshore Technology Conference.  The abstract is here: Warrington (1987) was … Continue reading OTC 5395 Revisited: Analysis of Cushioned Pile Hammers
