| Summary: | An engineering technique is proposed for calculating the
technical parameters of a pneumatic hammer for horizontal
clogging of steel pipes into the foundation of roads for the laying
of various communications – electrical cables, communication
lines, sewerage, etc. The method is based on the use of equation
of laws of conservation of energy and momentum. Examples of
horizontal clogging of pipes in a compressible soil are considered.
The concept of «additional mass» is introduced taking into
account the friction force of the soil the pipe. This value is added
to the weight of the pipe. This makes it possible to estimate the
efficiency of the transport of kinetic energy from the hammer to
the pipe as penetration of the pipe into the ground increases. |
