Abstract
A system for digging sewer pipe trenches without the need of manholes, including a pair of oppositely disposed parallel elongated sidewalls defining a work volume therebetween, at least one support member extending between the sidewalls, and a location guidance assembly positionable within. The guidance assembly includes a pair of spaced parallel elongated positioning members, at least one elongated connection member extending between the positioning members, a GPS sensor operationally connected to each positioning member, a laser support member connected to one of the elongated positioning members, a mounting connection connected to the laser support member; and a laser connected to the laser support member. A movement actuator is coupled to the location guidance assembly, wherein energization of the actuator moves the laser between a first position and a second position in the working volume.
