Abstract
An apparatus for cleaning a culvert includes a rod pushing and pulling machine, a rod string made from a series of extension rods coupled end to end, which rod string is mounted at a proximal end to the rod pushing and pulling machine. A debris removal tool is mounted on a distal end of the rod string. The debris removal tool may comprises a rod having a center longitudinal axis, a proximal end, and a distal end, the rod having a coupling at its proximal end. A bucket is mounted at the distal end of the rod, which bucket has an end opening positioned so that movement of the bucket along the culvert scoops debris into the bucket.
Claims14
An apparatus for cleaning a culvert, comprising:
- a rod pushing and pulling machine that comprises a motor vehicle;
- a rod string comprising a series of extension rods coupled end to end, which rod string is mounted at a proximal end to the rod pushing and pulling machine and extends forwardly from the rod pushing and pulling machine;
- wherein the rod pushing and pulling machine is a directional drilling rig capable of rotating the rod string about its lengthwise axis and
- a debris removal tool mounted on a distal end of the rod string, comprising a rod having a center longitudinal axis, a proximal end, and a distal end, the rod having a coupling at its proximal end configured for connection to a distal end of the rod string, and a bucket at its distal end, which bucket has an end opening positioned so that lengthwise movement of the bucket along the culvert scoops debris into the bucket.
An apparatus for cleaning a culvert, comprising:
- a directional drilling machine;
- a rod string comprising a series of extension rods having male and female threaded ends coupled end to end, which rod string is mounted at a proximal end to the directional drilling machine which can advance or withdraw the drill string from the culvert or rotate the drill string about its lengthwise axis;
- and
- a debris removal tool mounted on a distal end of the rod string, comprising a bucket having an end opening positioned so that movement of the bucket along the culvert scoops debris into the bucket.

- the rod string comprising a series of extension rods coupled end to end, which rod string is mounted at a proximal end to the rod pushing and pulling machine;
- a debris removal tool mounted on a distal end of the rod string, comprising a rod having a center longitudinal axis, a proximal end, and a distal end, the rod having a coupling at its proximal end and a bucket at its distal end, which bucket has an end opening at a proximal end of the bucket facing the rod pushing and pulling machine, so that pulling movement of the bucket along the culvert towards the rod pushing and pulling machine scoops debris into the bucket.
