Vibratory and Impact-Vibration Hammer Technology

Vulcan was involved in a great deal of research on vibratory technology. Most of this is presented on this page. It can be broken down into three parts: Articles and Monographs written by Vulcan personnel, during and after Vulcan's existence Material from the Soviet Union and Russia, the home of vibratory and impact-vibration technology Other … Continue reading Vibratory and Impact-Vibration Hammer Technology

Development of a Parameter Selection Method for Vibratory Pile Driver Design with Hammer Suspension

Don C. Warrington, P.E. Originally presented at the Colloquium of the Department of Mathematics of the University of Tennessee at Chattanooga 26 September 2006. Abstract This paper details the mathematical modelling of vibratory pile driving systems using a linear model with the objective of obtaining a closed form solution to estimate either the power requirement … Continue reading Development of a Parameter Selection Method for Vibratory Pile Driver Design with Hammer Suspension

Vibro-Engineering and the Technology of Piling and Boring Work

This work is an excellent and detailed treatment of the titled subject. We will present an English translation of the parts of the work that most directly deal with vibration and impact-vibration of piles and the equipment used to perform the work. You can click on the hyperlinked chapters to view them. Table of Contents … Continue reading Vibro-Engineering and the Technology of Piling and Boring Work

Driving Cylinder Piles

Editor’s Note: the term “cylinder piles” used in the section is a translation of a Russian term that is more exactly translated “shell piles” or “pile shells.” Since that term has an entirely different connotation in English (for one thing, it usually denotes a steel pile, while a concrete one is meant here) we use … Continue reading Driving Cylinder Piles

Driving Prismatic Steel Reinforced Concrete Piles

The mass vibration driving of heavy steel reinforced concrete piles was first done in the beginning of the 1950's with the aid of vibratory drivers of the VP-1 and VP-3 types (B. P. Tatarnikov). Several tens of thousands of steel reinforced concrete piles with a cross section up to 45 x 45 cm and a … Continue reading Driving Prismatic Steel Reinforced Concrete Piles

Installation and Extraction of Metal Sheet Piling

Editors note: from a practical, equipment standpoint, this is one of the most interesting sections of the book. It describes the first use of vibratory hammers on an actual project, and an interesting description of driving sheet piles and problems that can arise during that installation. The vibratory method of installation and extracting piles began … Continue reading Installation and Extraction of Metal Sheet Piling

Vibrating Drivers and Impact-Vibration Hammers

It was previously noted that vibration machines are classified with respect to dynamic action on the element to be driven (extracted) into vibrating drivers, impact-vibrating drivers-impact-vibration hammers, and also combined ones, in which both vibration and impact-vibration modes or their combinations can be realized. In most vibrating drivers and impact-vibration hammers the power of the … Continue reading Vibrating Drivers and Impact-Vibration Hammers

Methods for Approximate Calculation of the Parameters of Vibratory Drivers and Impact-Vibration Hammers

Calculation of the parameters of longitudinal-action vibrational pile drivers. The initial data for calculation are: the mass of the element to be driven mo, in kg; the geometric dimensions of the element to be driven;the depth of sinking l, in m; and the soil conditions. 1. The resistance of the soil is determined. The calculated … Continue reading Methods for Approximate Calculation of the Parameters of Vibratory Drivers and Impact-Vibration Hammers

Characteristics of the Dynamics of Vibration and Impact- Vibration Drivers

As indicated above, the questions of nonuniformity in the rotation of eccentrics and the limited drive power are as a rule considered in studying dynamic loads in the drive of the vibrodriver and vibrating hammer, and also in determining the power required. Nonuniformity in the rotation of the eccentrics is caused by: variation in the … Continue reading Characteristics of the Dynamics of Vibration and Impact- Vibration Drivers
