141 | Bedrock drilling and excavating apparatus | EP04101704.7 | 2004-04-23 | EP1589187A1 | 2005-10-26 | Lee, Chin-Yi |
A bedrock drilling and excavating apparatus receives power from a rotational power source to drive a drill to strike and shatter bedrock under the gravity of the apparatus and reciprocal vibrations of a pneumatic unit (50) located on the apparatus. The apparatus includes a coupling device (10) to couple with the rotational power source and an air intake vibration structure (12), a coupling sleeve (20) which has one end coupling with the lower end of a coupling axle and a connector which further couples to the pneumatic unit, and a drill (40) coupling to the pneumatic unit. The pneumatic unit drives the drill to vibrate up and down reciprocally to strike and shatter bedrock. The drill has a drill shell (41) which is alterable according to the diameter of the service shaft without changing the diamter of the pneumatic unit. The drill shell has a plurality of conical drill gimlets (42) mounted thereon in different biased angles to shatter the bedrock and improve drilling and excavating effect. |

A piling auger (1) includes a fixedly mounted element (5) which is arranged so as to extend beyond the circumference of the flight (3) of the auger (1). The element (5) is configured so that when the auger (1) is first rotated in a given direction and allowed to penetrate the ground to a predetermined depth, a first spatial volume is swept out by the element (5), and when the auger is withdrawn from the ground with continued rotation in the given direction and with concomitant supply of concrete or grout to the tip (4) of the auger (1) a second spatial volume is swept out by the element, the second volume being greater than the first volume. In this way, a pile having a circumferential helical concrete or grout projection is formed without undue disturbance to the surrounding soil during penetration, thereby enhancing the end bearing capacity and skin friction of the resulting pile. | ||||||

The invention relates to a concrete consisting of an aggregate which comprises, in dry weight and for obtaining 1 m3 of aggregate: between substantially 100 kg and 400 kg of cement and/or lime, between substantially 10 kg and 50 kg of an elastic substance, and between substantially 500 kg and 1,800 kg of flying ashes and/or sand. For creating in a ground a pile (3) made of such a concrete, a drill is screwed in the ground (1) for digging therein a shape corresponding to the shape of said pile, while pushing the ground material forced by the drill into the surrounding ground, the drill is then unscrewed for bringing it up to the ground surface, and the space released in the ground by unscrewing the drill is provided with the above concrete which is injected through the drill. | ||||||

155 | TWIST DRILL WITH ASYMMETRICALLY SPACED SUPPORT MARGINS | EP97914431.0 | 1997-03-25 | EP0891239A1 | 1999-01-20 | HOWARTH, Bertram, Victor; GOODWIN, Richard |
A helical twist drill has fluted lands (6) each having projecting from their radially outer faces a plurality of circumferentially spaced support margins (21, 22, 23, 24). At least one of the suport margins (24) is asymmetrically spaced with respect to the other support margins (21, 22, 23). | ||||||
156 | Rotary drill bit with gage definition region, method of manufacturing such a drill bit and method of drilling a subterranean formation | EP98302621.2 | 1998-04-02 | EP0869256A2 | 1998-10-07 | Tibbitts, Gordon A. |
A drill bit (10) and method of drilling employing a gage definition region (30) on the bit to relatively gradually and incrementally increase the diameter of the borehole being drilled from a diameter that is cut by fixed face cutters (20) or rolling cone cutters on the bit body to a larger diameter. Preferably, the diameter of the gage definition region defined by cutting structures thereon varies along a longitudinal length of the bit, being smallest nearest the leading end of the bit. In a preferred embodiment, the gage definition region includes a plurality of helically arranged cutting elements (26) disposed around the perimeter of the gage definition region. Such a configuration of cutting elements helps to reduce the loading on, and wear of, each individual cutting element. Thus the effective life of the bit is extended by enhancing its ability to drill the borehole to the gage diameter over a longer interval than may be achieved with conventional bit designs. |
