Abstract:
This paper deals with a new model of the booms梩he directing boom with corridor. A theoretical and experimental study was done by author in hydro-technical laboratory of the Leningrad Forestry Academy at the U. S. S. R.The directing boom with corridor might be used on those rivers where the velocity of flow should be in the range 1.5m/s to 3.0m/s, their depth should be less than 3m and the specific density of the driving logs should be less than 0.95.The constructive dimensions of the boom with corridor are given in this paper on a basis of analysis of the experimental data. It is recommended that the width of the main boom should be 1.2m, the depth of the draft legde of the boom could be changing in the range 0.4m to 0.6m and the width of the corridor could be changing from 4m to 6m, but not be less than the length of the driving logs.
