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
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
The last in our series of historical sheeting sections are Belval sheeting sections, including BZ-I N, BZ-II N, BZ-III N, BZ-IV N, BZ-1 R, BZ-II R, BZ-III R, BZ-IV R, BZ-III A, BZ-IV N-50, and BZ-V N. They are all Z-sections featuring double jaw interlocks. Belval sheeting was originally from Luxembourg, not far from Vulcan's … Continue reading Historical Belval Sheeting Sections
