Design of a machine for trenchless pipe replacement using the static cracking method

Abstract

Efforts to minimize surface disturbances during earthworks are an important aspect of modern civil engineering. These expectations are met by a number of technologies that make it possible to carry out such works using trenchless technologies. The static cracking method makes it possible to extend, modernize or renovate the existing underground infrastructure. The paper presents the design of a device assigned for trenchless pipe replacement using the static cracking method. The developed device is characterized by the use of a new type of drive system with the use of articulated rods. In addition, the work proposes ways to solve the main issues in the design of this type of device.
