However, the service life of many pipelines at the moment is several decades. In this regard, the number of emergency situations is increasing. Moreover, the degree of their impact on infrastructure and the environment is increasing from year to year.

The dependence is obtained, which allows determining the force of penetration of the cutter of the milling working equipment into the soil.Discussion and conclusions. It is recommended to use the results of the performed theoretical studies for calculating the design and operating parameters in the design and creation of milling working equipment. |
