A drill including a drill flight where the drill flight changes angle from a primary flight angle (A1) to a secondary flight angle (A2).

A rotary drive machine for the installation of helical pile sections through installation openings in a slab floor inside of a building perimeter. A vertical frame having an upper end and an open lower end is positioned over an installation opening through which it is desired to rotationally install a helical pile section, and the vertical frame anchored to the slab floor. A rotary power means, attached to the helical pile section moves along a vertical movement guide and is driven by a vertical actuator to rotationally and vertically drive the helical section into the ground. A method of use is also disclosed.

An assembly and method of simultaneously spin drilling and pressure grouting a helical anchor into the ground vertically, horizontally or at an inclined angle create a continuous grouting configuration inside and outside the helical anchor for its entire depth in the ground. The helical anchor is configured to be partially or completely removed as desired and can be provided at its upper end with a tensioning element to post tension a cementitious foundation structure. A unique spin drilling and grouting assembly continuously provides grout under pressure to the interior of the helical anchor during its spin drilling into the ground. In one embodiment, the pressure grouted helical anchor is used with an upwardly extending tensioning element to reinforce cementitious foundation caps or other concrete support foundations.

A foundation support apparatus is provided and includes a tubular piling with a rib of material fixed to an exterior or outer surface of the piling. The rib provides improved total resistive force capabilities for the support apparatus, as compared to a bare piling. The rib is positioned and dimensioned as to not impede the installation of the piling. The rib may be circular or helical, continuous or discontinuous, and is disposed coaxial with a longitudinal axis of the piling. The foundation support apparatus may be manufactured on a construction site to readily improve the load capacity of various types of vertical foundational systems, such as driven pilings. The foundation support apparatus may be encased or backfilled with grout materials which harden around the ribs of the apparatus forming an interlocking engagement between the grout and the ribs, thereby increasing load resistance capabilities of the support apparatus.

A machine and method utilize a tracked undercarriage including a frame with a central body, front and rear transverse assemblies connected to the central body and extending on opposite sides. Each of a pair of lateral tracks is connected, at the front and at the rear, to ends of the transverse assemblies. The base machine includes excavation equipment having different working positions/configurations. Each of a pair of front load cells of the tracked undercarriage is mounted between a lateral track and the front transverse assembly. Each of a pair of rear load cells is mounted between a lateral track and the rear transverse assembly. Each load detects force data indicating the reaction force exerted between the associated lateral track and the respective transverse assembly. A control system computes a barycentre planar position of the machine situated substantially at a reference plane computed as a function of the force data.

A device measures the flow rate of a fluid, such as concrete, in a pumping plant connected to a drilling machine provided with a drilling tool. The pumping plant includes a motor pump and a connection pipe to lead fluid from the motor pump to the drilling tool. The device includes a transmitting module, for rigidly and removably mounted on the pumping plant and including an accelerometer and a receiving module, associated with the drilling machine. The transmitting module detects accelerations generated by vibrations of the pumping plant during the pumping of the fluid. The accelerations indicate flow rate of the fluid. The transmitting module wirelessly sends a signal, which is processed based on the detected accelerations, to the receiving module. The receiving module receives the signal from the transmitting module and sends a signal indicating the flow rate of the pumped fluid based on the received signal.
