Embodiment Construction

[0024] A. Overview of Exemplary Drilling Equipment

[0025] figure 1 A drilling apparatus 20 is shown having features in accordance with the principles of the invention. Generally, apparatus 20 includes a plurality of tubular sections 22 joined together in end-to-end relationship to form drill string 24 . Each of the tube sections 22 includes a drive shaft 26 rotatably mounted in a housing assembly 28 . Drill head 30 is mounted at the distal end (ie, leading end) of drill string 24 , while drive unit 32 is located at the proximal end (ie, trailing or trailing end) of drill string 24 . The drive unit 32 includes a torque driver adapted to apply torque to the drill string 24 and an axial driver for applying a thrust or pull back force to the drill string 24 . Push or pull back forces from the drive unit 32 are transmitted between the proximal and distal ends of the drill string 24 through the housing assembly 28 of the tubular portion 22 . Torque is transmitted from the prox...

Abstract

The present disclosure relates to a drilling apparatus including a cutting unit defining at least one through-hole that provides fluid communication between a distal side and a proximal side of the cutting unit. The cutting unit includes a plurality of cutting elements at the distal side of the cutting unit. The cutting unit also includes a shutter for selectively opening and blocking the through- hole of the cutting unit.

Description

[0001] This application was filed on March 15, 2010 as a PCT International Patent Application for applicants other than the U.S. who are designated as Keith Allen Hoelting, a U.S. citizen, Andis Salins, and Stuart Harrison, an Australian citizen. All of the designated national applicants are Vermeer Manufacturing Company, a U.S. national business. technical field [0002] The present invention relates generally to non-trenching drilling equipment. More specifically, the present invention relates to drilling equipment capable of maintaining precise slopes and lines. Background technique [0003] Modern installation techniques provide the underground utility services needed for community infrastructure. Sewerage, water, electricity, gas and telecommunication services are increasingly being located underground to improve safety and to create a more visually pleasing environment that is not cluttered with visible utilities. [0004] One method used to install underground utili...
