Method and apparatus for digging and installing curved sewers

摘要

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.

1. A system for digging sewer pipe trenches without the need of manholes, comprising:
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 work volume and further comprising:
a pair of spaced parallel elongated positioning members;at least one elongated connection member extending between the positioning members;a respective positioning sensor operationally connected to each respective positioning members;a straight-line generator support member operationally connected to one of the elongated positioning members;a mounting connection operationally connected to the straight-line generator support member; anda straight-line generator operationally connected to the straight-line generator support member; and a movement actuator operationally coupled to the location guidance assembly; wherein energization of the actuator moves the straight-line generator between a first position and a second position in the working volume.
