ANALYSIS OF SOME PROBLEMS AND REQUIREMENTS FOR NEW SOUND RESONANT UNITS FOR TRENCHLESS LAYING OF PIPELINES BY VIBRATION METHODS
Kiriencko Elena Anatolyevna, – Candidate of Technical Sciences, associate professor of Applied Fluid Mechanics and Mechatronics Department of NTUU «Igor Sikorsky Kyiv Polytechnic Institute» (03056, Kyiv, Prospect Peremohy, 37).
This article continues the series of works, which are devoted to studies of vibration methods of pipe laying, with purpose of increasing the productivity through higher speed of driving, penetration capacity, possibility to overcome the great frontal resistance of soil at acceptable energy consumption. The studies have been fulfilled on the base of wave theory of stress propagation in going downward pipe and in soil.
This article analyzes some of the challenges facing designers of sound-resonance units for vibro-puncture and vibro-compression, operating in a wide range of laid pipes and in different soil conditions while constructing underground passages not only under motor roads, highways and railway embankments but also under bottom of various water basins which can be carried out by trenchless methods.
There has been conducted the analysis of the high frequency vibrators existing abroad, which are suitable for work in sound resonance modes, in particular, quarter wave and unpaired multiple to it “three-quarter wave” and “five-quarter wave” modes. Existing drives, able to provide the possibility for high consumed power achievement, have been analyzed, which may be necessary while constructing long lengths under water pathways (up to 300 m) with the use of sound-resonance units.
Some examples of necessary technical characteristics for new sound-resonant installations for vibro-puncture and vibro-compression are given; basic requirements for these installations are formulated.
