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
For the rest of the book, click here. In a relatively short period of time that has passed since the time when the method of vibrating immersion of metal sheet piles was successfully applied for the first time in production conditions, the vibration and crane equipment used and the methods of work have changed radically. … Continue reading Basic data of production experience and technical and economic indicators of vibration immersion of metal sheet pile
Editor's Note: the term "pile drivers" or "piling headframes" means what we would call today a dedicated rig. Before the advent of crane lifted and controlled pile driving, people would use a specialty mast type of arrangement--skid or turntable mounted--to drive piling, dragging it from one pile to the next. The arrangements shown here are … Continue reading Features of the Technology of Vibratory Immersion of Sheet Piling Using Piling Headframes
Editor's Note: this is an interesting overview of the installation of sheet piles using a crane. It can be compared with the post Installation and Extraction of Metal Sheet Piling. The composition of the main equipment for the performance of work on the vibro-immersion of a metal sheet pile, in addition to the vibratory pile driver, … Continue reading Production of Works for Immersion of Metal Sheet Piles Using Jib Cranes
For the rest of the book, click here. Editor's note: this is the beginning of the section concerning the application of vibratory drivers to sheet piles. One problem described here was keeping the sheets in alignment and now allowing them to get out of alignment (the "fan" effect described in below) which only gets progressively … Continue reading Manufacture of works on vibration immersion and extraction of metal sheet piling: General Information
https://youtu.be/a1UUXuO2Ia0 This is a video clip of a yard test of the Foster 1800 vibratory driver at Vulcan Iron Works' Chattanooga, TN factory where it was made. The driver was the result of a program of Vulcan manufacturing L.B. Foster's vibratory drivers. The 1800 exciter was built from Foster's existing specifications, down to the lever … Continue reading Foster 1800 Vibratory Yard Test
Editor's Note: this is a topic that has occupied quite a lot of space on this site, starting with Russian Impact-Vibration Pile Driving Equipment and continuing with other pieces. That piece deals some with the early history but is more concerned with the development subsequent to this book at the VNIIstroidormash institute in Moscow. It is … Continue reading Impact-Vibration Hammers
For the rest of the book, click here. The scheme of a pile vibratory driver with a sprung load provides for the implementation of a narrow load in the form of additional elements that are laid on the sprung part and move when immersed together with the pile. This method has well-known advantages, the most … Continue reading Vibratory Downcrowding Units
