Underground piping construction system with horizontal moat intelligent robot

Abstract

In recent years, the slope horizontal drilling method for non-open underground piping construction has become widespread, and realization of demands for the removal of utility pole is proceeding. However, these development technologies require construction area and development of smart excavation technology that can avoid multiple underground piping such as intersections and obstacles is required. In this newly developed drilling method, all the drilling facilities are accommodated in manhole pits. It is an underground piping construction system that enables precise horizontal control by liquefaction excavation without discharging earth and sand between manhole pits.
