摘要： A pneumatic ground piercing tool according to the invention has a reversing mechanism provided as part of the air distributing mechanism. Such a tool includes an elongated tubular housing having a rear opening, a head assembly including an anvil, a striker disposed for reciprocation within an internal chamber of the housing to impart impacts to a rear impact surface of the anvil for driving the body through the ground, an air distributing mechanism for effecting reciprocation of the striker, and a tail assembly mounted in a rear end opening of the housing that secures the striker and air distributing mechanism in the housing. In one embodiment, the outer bushing of the valve sleeve can slide a short distance relative to the air supply tube and has an intermediate radial port which selectively communicates with the air supply conduit. The valve sleeve also includes a detent mechanism for securing the air supply tube in its forward or reverse position. A biasing device such as an resilient tube biases the detent mechanism to an unlocked position when the compressed air is off, and is overcome by air pressure so that the detent assumes a locked position when the compressed air is on.

摘要： Methods and apparatuses for producing a planar cavern are provided. The planar cavern is formed by first creating a continuous bore that extends through a subsurface resource deposit. The drill head used to create the bore can be steered in response to information about the concentration of the resource in the strata through which the drill head is passing, in order to keep the bore within resource deposit. The continuous bore can be formed by connecting first and second bores at a point within the subsurface resource deposit. After the continuous bore has been formed, a sawing assembly is placed within the continuous bore. The sawing assembly is then moved, in a continuous or in a reciprocating fashion, within the continuous bore. As the sawing assembly is moved, it is maintained under tension, to create a planar cavern. By thus exposing a large area of the resource deposit, a relatively large amount of the resource deposit can be dissolved in a solvent introduced to the planar cavern per unit time. Saturated solution can then be pumped from the planar cavern, and the resource recovered from the saturated solution by evaporation.

摘要： A method of replacing an existing underground pipe, especially a sanitary sewer line, uses a boring machine that advances a drill string of hollow rods through the existing pipe. The method includes the steps of mounting a rotary cleaning tool on a distal end of the drill string, moving the cleaning tool progressively through the underground pipe while rotating the drill string in order to clean the inside of the pipe, flushing debris loosened by the cleaning tool from the pipe using a pressure fluid, removing the cleaning tool from the drill string and mounting a camera assembly on the distal end of the drill string, moving the camera and drill string through the underground pipe on the drill string and inspecting the inside surface of the pipe with the camera, removing the camera from the drill string and replacing it with a pipe destroying apparatus, moving the pipe destroying apparatus through the pipe to destroy the existing pipe, and then installing a replacement pipe along the same line as the destroyed existing pipe. This permits a single piece of equipment, such as a directional drill rig, to perform several different functions as part of the pipe replacement process.

摘要： An impactor for use with a directional boring machine for replacement of underground pipes includes a bursting head having a rearwardly opening recess and a front end opening that communicates with the recess. An inlet pipe is connected at its front end to a distal end of the drill string and extends into the recess of the bursting head through the front end opening. A striker is mounted for sliding movement along the inlet pipe, and a distributing mechanism responsive to pressure fluid supplied through the drill string and inlet pipe causes the striker to reciprocate in the rearwardly opening recess of the head to deliver forward impacts against the bursting head. The striker and distributing mechanism are mounted in a tubular housing, and a pulling connection is provided by which the impactor can be pulled by the drill string while the striker is delivering impacts against the head in the same direction as a pulling force exerted by the drill string. The bursting head is preferably slidably mounted on the inlet pipe and moves forward relative to the inlet pipe and drill string in response to an impact of the striker against the bursting head. The impactor can be readily used with existing directional boring machines.
