|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.

In 1988, while still at Vulcan, I made my first visit to the then Soviet Union with my brother Pem, our Executive Vice President. The visit had some interesting twists and turns along the way. One side trip from Moscow was to Leningrad (now St. Petersburg,) where we were able to view a B-402 vibrator drive sheet piles. (A contemporaneous account of the visit is given below.) Although we never really pursued further commercial discussions, one thing we were sent was the book Vibro-Engineering and the Technology of Piling and Boring Work, parts of which we reproduce here in translation.
Although it is acknowledged that vibratory (and impact-vibration hammers) were brought into practical use in the Soviet Union, there are very few details of this readily available. (Most of them are probably on this website!) The publishing of the English translation here will hopefully fill in some of the history and perhaps advance the technology in its present form.
Vulcan commissioned Language Services in Knoxville, TN, to translate the parts of the work that are presented here. Although we freely admit that some of the translation is too literal, the content is of sufficient value that it merits posting. We have edited the text some to make the nomenlcature more in line with terminology used in the U.S.
Visit to Leningrad (April 1988)
In Moscow we went to Leningrad Station about 2300 to take the train to Leningrad. We were met by Mr. A.A. Orlov, Chief Engineer of the All-Union Construction and Energy Mechanization Organization of the Ministry of Energy and Electrification of the USSR, and his assistant. We then took the train to Leningrad and arrived about 0830.
We were met there by a delegation from the Organization, which first took us to the Moscow Hotel where we got a room and prepared for the day. Included in the delegation were E.A. Narozhnitskii, (Director) and M.L. Pevzner of the Leningrad Experimental Factory of Construction Machinery. We then went to a jobsite in Leningard, where they were building a tunnel under the river. They had been working on this project for a year and had managed to drive some sheet piling. Their vibratory hammer was driving some Laarsen sections about 24m in length, which they did using their vibratory hammer. On the vibratory, an electric motor mounted in the suspension plate on top of the hammer and a chain drive system extending from the suspension to the gearbox. The clamp is able to drive only one sheet at a time. The hammer is electric, about the eccentric moment of the 1150 but with about half of the power. The power comes from the electric power grid (that is to say, they plug it in somewhere), and they have a control box to provide the necessary circuitry to start and stop the 3-phase motors. In spite of the potential to gear up or down, the electric motor and eccentrics both rotate at1500 rpm, and they have other models that are slower. It took them about 5-10 minutes through the glacial till they were driving through. The hammer is quiet though and, without the power pack, the noise was limited.
After this, we went on and eventually had lunch back in the Moscow Hotel. After lunch, about 1530, we sat down for a conversation about the hammers. We explained the construction and operation of our equipment, but they thought that we used too much power for our eccentric moment, that we were wasting power and that our additional power could not accomplish anything. I replied that the only way to know this for sure was to run a race amongst the units and see. They also told us that they thought electric vibratory was better and planned to stick with it in their programme. Nevertheless, the door was kept open by both sides for further discussion, as they felt that there was potential for this. We also invited them to Chattanooga (our headquarters) for further discussions.
