From the experience of examining the surfaces of concrete and isolating gaskets directly under the hammer’s shabot, after a certain period of time after its operation, strong deformations of the gaskets are always found, and sometimes even the destruction of the concrete surface. This allows you to evaluate the order of stresses developing under the hammer shabot in several tens of kg/cm2. Therefore, from the existing calculations to determine the stresses under the hammer Shabot, one should give preference to the calculation that gives maximum stress, since until experimentally the values of the actual stresses are somewhat risky for calculations that do not give reserves of strength.
