摘要： A method and apparatus for installing a pile or load-bearing element into soft ground, wherein a non-percussive force, rather than a percussive force such as that applied by a hammer or a jack, is applied to the top of a hole-forming tool or pile (1) so as to push the hole-forming tool or pile (1) in a substantially continuous motion to a first depth into the ground, and wherein the hole-forming tool or pile (1) is then pushed in a non-percussive manner to a second depth while being simultaneously rotated. There is also disclosed a method and apparatus for forming a cast-in-situ pile in soft ground by pushing a hole-forming tool (1) provided with fins (3) at its base into the ground. Once the required level has been reached, the hole-forming tool (1) is rotated and concrete or grout is pumped through the body of the hole-forming tool so as concomitantly to help displace and replace the soil swept away by the fins (3). The hole-forming tool (1) is then withdrawn, and further concrete or grout is supplied so as to form a predictably-shaped pile with enhanced bearing capacity.

摘要： A method of forming a cast-in-situ pile with an enlarged head, wherein a collar (1,13) is releasably affixed to the lower end of a piling tool (10) and the piling tool (10) and the collar (1,13) are driven to a first depth and the collar (1,13) is released from the piling tool (10). The piling tool (10) is then driven to a second depth, the piling tool (10) passing freely through a central aperture (2,14) of the collar (1,13), which remains at the first depth. The piling tool (10) is then withdrawn, and concrete or grout (20) is supplied to the lower end of the piling tool so as to form a cast-in-situ pile (22). When the lower end of the piling tool (10) again reaches the first depth, the collar (1,13) is lifted from the ground and concrete or grout (20) is supplied into the void left thereby so as to form a pile (22) with an enlarged head (23).

摘要： There is disclosed a method of continuous flight auger piling and a continuous flight auger rig (1), wherein an auger (2) is applied to the ground so as to undergo a first, penetration phase and a second, withdrawal phase, and wherein the rotational speed of and/or the rate of penetration of and/or the torque applied to the auger (2) during the first, penetration phase are determined and controlled as a function of the ground conditions and the auger geometry by means of an electronic computer (8) so as to tend to keep the auger flights loaded (11) with soil originating from the region of the tip of the auger (2). During the withdrawal phase, concrete (14) may be supplied to the tip (12) of the auger (2) by way of flow control and measuring means (6, 7), the rate of withdrawal of the auger (2) being controlled as a function of the flow rate of the concrete (14), or vice versa, by means of an electronic computer (8) so as to ensure that sufficient concrete (14) is supplied to keep at least the tip (12) of the auger (2) immersed in concrete (14) during withdrawal.

摘要： A waterbar for use between adjacent panels (22, 24) in a diaphragm wall, the waterbar comprising a first member (5) in the form of an elongate strip (6) provided along a first longitudinal edge (8) with a hydrophilic material (7) and along the opposite longitudinal edge (9) with a retaining channel (10), and a second member (12) in the form of an elongate strip (13) provided along a first longitudinal edge (15) with a hydrophilic material (14) and along the opposite longitudinal edge (16) with a keying projection (17). The retaining channel (10) of the first member (5) is shaped so as to slidably retain the keying projection (17) of the second member (12), and either the retaining channel (10) or the keying projection (17) is provided along its length with a hydrophilic material (18) which serves to seal the joint between the first and second members (5, 12). The first member (5) is installed when casting the first (22) of the adjacent panels (22, 24) of the diaphragm wall, whereas the second member (12) is installed when casting the second (24) of the adjacent panels (22, 24). In this way, prolonged exposure of the hydrophilic material (7, 14, 18) to water during installation is reduced, and the integrity of the joint is improved.

摘要： 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.

摘要： There is disclosed a method and apparatus for testing the static load-bearing capacity of a pile, wherein a test load is applied to the top of the pile (2) by way of a jack (1) braced against a reaction member (3) and the magnitude of the test load and the resulting displacement of the pile are measured and communicated to an electronic computer (7). The electronic computer (7) issues control signals to the jack (1) in response to the measured magnitude of the test load so as to apply a predetermined regime of test loads to the top of the pile (2). By automatically monitoring the applied test load, it is possible to maintain a desired load with a high level of accuracy for an extended period of time without the need for operator intervention.
