摘要： A tricone type of drill bit assembly (10) including an arrangement of lugs (18) which rotatably support cone-type cutter heads (30, 32, 34), specifically three such cutter heads, circumferentially about a common central axis (26) of the assembly (10) such that a segment of each cutter head defines a corresponding segment of the drill face (44) of the assembly between its central axis (26) and the outermost periphery of its drill face. The particular drill bit assembly (10) disclosed herein is an improvement over known such assemblies in that it provides at least one high pressure fluid cutting jet (42) located between two of the cutter heads at a point radially spaced inward from the outer periphery of the assemblies drill face. In particular embodiments shown, a number of such cutting jets are provided along a radial line between the outer periphery of the drill face and the common axis (26) of the assembly.

摘要： The present invention is a hydraulic excavation and delivery device capable of hydraulically removing soil overburden from a buried structure, like a pipeline, and delivering an article, such as an electro-mechanical connector for attachment to the buried structure. Hydraulic excavation is achieved by directing a stream of fluid at soil adjacent to and inside an open bottom region of the device to simultaneously dislodge adjacent soil, suspend dislodged soil in the accumulating fluid and form a pit that the device may fit within. Delivery of article is achieved by: (1) loading an article into the tool; (2) advancing the device toward the buried structure by deepening the pit without significant failure (slumping or sagging) of the pit walls until a portion of the buried structure is exposed and within the device; (3) landing the device on the exposed portion of the structure; (4) fixing the article to the exposed portion of the structure; and (5) releasing the article from the device.

摘要： A dual circulation fluid hammer drilling system (10) has a fluid hammer (12) which is coupled to a drill string (14). The system (10) utilises a first fluid (16) and a second fluid (18). The first fluid (16) is delivered through the drill string (14) to drive or otherwise power the fluid hammer (12). The second fluid (18) is also delivered through the drill string (14) but in isolation of the first fluid (16) so they do not mix within the drill string (14). The second fluid (18) passes through a hammer bit (38) of the hammer drill (12) and is directed to flow out from a bit face (20). Thus when the system (10) is in use the second fluid (18) will flow across the bit face (20). The first fluid (16) also exits the drilling system (10) at the hammer drill (12). However the first fluid (16) exits upstream or up-hole of the bit face (20).
摘要翻译：双循环流体锤钻井系统（10）具有连接到钻柱（14）的流体锤（12）。系统（10）利用第一流体（16）和第二流体（18）。第一流体（16）通过钻柱（14）输送以驱动或以其他方式对流体锤（12）供电。第二流体（18）也通过钻柱（14）输送，但是与第一流体（16）隔离，因此它们不会在钻柱（14）内混合。第二流体（18）穿过锤钻（12）的锤头（38）并被引导从钻头面（20）流出。因此，当系统（10）在使用中时，第二流体（18）将流过钻头面（20）。第一流体（16）也在锤钻（12）处离开钻井系统（10）。然而，第一流体（16）离开钻头面（20）的上游或上部孔。
