For the rest of the book click here. Currently, several methods are known for trenchless pipe laying: puncture - pressing closed pipes, punching with simultaneous development and removal of soil from the pipe and horizontal drilling. For trenchless installation of pipes with a diameter of up to 500 mm, used as casings for laying pipelines … Continue reading Use of Vibratory Hammers for Trenchless Pipe Laying
For the rest of the book click here. Recently, some construction organizations have begun to use the vibration method for immersing and removing large-diameter casing pipes. At Stalingradgidrostroy recently [65], a hydrovibration method for immersing pipes with a diameter of 400-500 mm has been developed and successfully implemented. Using this method, it was possible to … Continue reading Drilling Using Vibration of Deep Dewatering and Artesian Wells
This is another in a series of technical reports on vibratory and impact-vibration pile driving equipment. It is scheduled to be presented at the 2024 Arts and Research Conference at the University of Tennessee at Chattanooga. You can download the paper here. The abstract is as follows: Abstract: Driving piles by longitudinal vibrations has been … Continue reading Analysis of Vibratory Pile Drivers using Longitudinal and Rotational Oscillations with a Purely Plastic Soil Model
Showing off the product: a diagram of Vulcan's product line exhibition at the Pan-American Exhibition in Buffalo, NY, in 1901. Vulcan participated in most of the "world's fairs" of the era, including the Columbian Exhibition in Chicago. It's worthy of note that all of the products shown here: the leaders, the #2 steam hammer, the … Continue reading Vulcan’s Awards at the Columbian (Chicago, 1893) and Pan-American Expositions (Buffalo, 1901)
The rest of the book is here. Both of these topics would also occupy Vulcan and the construction industry. In the late 1950's and early 1960's Vulcan would develop its Sand-Drain hammers, but as you can see the Soviets were already doing this installation using vibratory drivers. (For an overview of sand drains and Vulcan's … Continue reading Construction of concrete cast-in-place piles and sand piles-drains using the vibration method
For the rest of the book, click here. By "shells," the Russians mean large concrete cylinder piles. Raymond Concrete Pile was developing their own prestressed cylinder piles for work in Venezuela and the Chesapeake Bay Bridge/Tunnel, with diameters up to 66". For their part the Russians were installing working piles up to 1.55 m (61") … Continue reading Application of Low-Frequency Longitudinal Vibratory Hammers for Immersion of Hollow Piles and Shell Wells into the Ground
For the entire book, click here. This is something of the "Holy Grail" of the whole vibratory project: the ability to estimate the static capacity of piles driven by vibration. The Soviets took up the question early in the development of these machines and ran into the same obstacles that most everyone since then has … Continue reading About the Bearing Capacity of Piles Driven by Vibration
For the rest of the book, click here. Driving concrete piles by vibration is still not as accepted as it should be, but doing it has preoccupied researchers both geotechnical and equipment application since the early days of the technology. The Soviet approach to it was to use low speed, high eccentric-moment vibrators, a practice … Continue reading Production Experience of Driving Heavy Reinforced Concrete Piles with Low-Frequency Longitudinal Vibratory Hammers
For the entire book, click here. This is an interesting section for many reasons, but we can mention two: it's the first reference in the book to diesel hammers (up to now the vibratory drivers have been competing with air/steam hammers) and it's the first reference for letting the vibratory driver bounce on the pile … Continue reading Vibratory Driving of Light Piles
For the rest of the book, click here. With the right choice of equipment and organization of work, vibratory extraction of sheet piles, as well as driving, makes it possible to use stock metal sheet piles more widely than before, which contributes to a sharp increase in labor productivity and a reduction in the cost … Continue reading Work on Vibratory Extraction of Metal Sheet Piles from the Ground
