Experiences of GAZ-SYSTEM S.A. in the application of microtunneling technology for the construction of trenchless sections of the gas transmission network

Microtunneling is a commonly used trenchless technique by GAZ-SYSTEM S.A., the primary technique for performing short crossings of single obstacles. This technology provides a high degree of confidence in the successful completion of the crossing. However, the method of performing microtunnels and the additional technologies that are associated with their use are not found in traditional implementations carried out by other network operators, e.g. for water or sewer. These additional technologies, as well as experience in the implementation of microtunnels with steel pipes, will be in this presentation.
