Scheme of the device of the vibrator of the simplest type. The vibrator consists of an electric motor 1, a directional vibrator 2 and a head 3; the design may also include loading plates 4. In the process of translating and putting online Savinov and Luskin's classic work The Vibration Method of Driving Piles and … Continue reading About Those Vibratory Suspensions…
For the rest of the book, click here. Vibratory hammers with spring load (Figure 35) were proposed by the authors in 1950.* Unlike machines of the simplest type with rigidly connected elements, this vibratory driver consists of two parts - a vibrating one, which includes a vibrator 1 and a cap 2, and a part … Continue reading Suspended Vibratory Hammers
In the midst of posting The Vibration Method of Driving Piles and Its Use in Construction, it's worth stopping and looking at the first successful vibratory driver: the BT-5, developed by D.D. Barkan and his associates and first used at the Gorky hydroelectric project in 1949. It was the first successful use of a vibratory driver … Continue reading D.D. Barkan’s BT-5 and the Vulcan 400
For the rest of the book, click here. The main distinguishing feature of the simplest type of vibrodriver (Figure 27) is that all its parts are connected to each other and to the submerged body into one common whole. The vibrator consists of an electric motor 1, a directional vibrator 2 and a head 3; … Continue reading Vibrators of the Simplest Type
For the entire book, click here. Vibratory machines for plunging sheet piles, piles and pipes into the ground should be classified according to the type of dynamic effect on the immersed body, the device diagram. and drive type. According to the first sign, these machines are divided into two main groups: pure vibratory action - … Continue reading Vibrating Machines For Sheet Piling, Piling And Pipe Driving: Introductory Remarks
Editor's Note: this is the original presentation of the "Savinov and Luskin Method" for sizing a vibratory driver for a specific application. It has been reproduced in many publications and in various forms. I would remind my readers that the method is presented here in Those Pesky Kilogram-Force Units. For successful pile driving in each case … Continue reading Practical Methods for Selecting the Parameters of a Vibratory Pile Driver
For the rest of the book, click here. The significant complexity of the phenomenon of vibrational immersion of bodies into the ground and the difficulties associated in choosing the optimal parameters of pile vibratory drivers prompted many researchers to attempt to construct a theory of vibrational immersion and vibroextraction. Work on the creation of such … Continue reading Existing Proposals for the Theory of Vibratory Pile Driving
For the rest of the book, click here. The main factors that determine the process of immersion in the ground (or extraction from the ground) of a pile subjected to vibration are the intensity of vibrations and the value of the resultant of external statically acting forces applied to the pile. Consider the influence of … Continue reading Factors on which the speed and depth of immersion of a pile subjected to vibration depend
Citation: O. A. Savinov and A. Ya. Luskin, The Vibration Method of Driving Piles and Its Use in Construction [in Russian], Gosstroiizdat (1960). Scientific editor - Dr. tech. Sciences Prof. D. D. Barkan. In a form accessible to the engineer, this book outlines the basics of theory, technology and experience production application of the vibration … Continue reading The Vibration Method of Driving Piles and Its Use in Construction
Immersion in the ground of bodies subjected to vibration represents a complex mechanical phenomenon. Let us consider the features playing the most significant role in the process of vibration immersions so you can correctly understand the mechanism of this process. Imagine that at the head of a pile immersed in the ground to a certain … Continue reading Physical and Mechanical Features of the Phenomenon of Vibration Immersion
