摘要： An elongate rectilinear rigid member (10) is arranged, consisting of a rod (11) connected to or rested against an enlarged bottom member (12). A driving tube (21) is arranged around the rod (11), with a lower edge of the tube abutting against the enlarged bottom member (12). The assembly of elongate member (10) and driving tube (21) is controlled by a thrust, or percussion, or roto-percussion, or vibration movement, or a combination thereof, so as to drive the member (10) in the soil. A hole (F) is obtained, which is drilled around the rod (11). The driving tube (21) is removed from the hole, and a consolidating mixture is optionally injected in the hole drilled around the rod (11).

摘要： To form columns of consolidating material having a non-circular section in the soil, the method comprises the steps of:
- introducing into the soil a rotatable rod (55) having, near an end thereof, a radial nozzle for injecting pressurized consolidating liquid;
- translating and rotating the rod (55) at controlled speed while injecting pressurized consolidating liquid.
During rotation of the rod (55) its speed of rotation is varied between a minimum value, at which the penetration distance of the liquid into the soil is maximum, to a maximum value, at which the penetration distance of the liquid into the soil is minimal.

摘要： A set of primary blocks of artificial conglomerate (10, 11) spaced apart from each other around the portion of ground (T) which has to be excavated is formed using jet grouting techniques in a vertical plane transverse to the axis of the tunnel which has to be excavated. A set of infill blocks of artificial conglomerate (20, 21) each located between two consecutive primary blocks in order to firmly connect them together is then formed. Each infill block has an outer portion (22) which extends over the outer surfaces (13-16) of two consecutive primary blocks (10, 11). A continuous closed ring structure is thus obtained. By repeating these operations alongside the structure already formed, a continuous tubular structure of artificial conglomerate is obtained.

摘要： A trench rig (1) for excavating continuous monolithic brattices or bases, presenting a self-propelled crawler truck (2), a chain-driven excavating tool (6) provided with a central column (9) which extends along a working axis (A), and a control unit (8) for the column (9) presenting a fixed gripper (15) in relation to the truck (2) and a mobile gripper (16) in relation to the fixed gripper (15) itself; the two grippers (15, 16) are slidingly coupled to the column (9), and can be selectively engaged to the column (9) itself in order to move the tool (6) along the working axis (A), and are connected to each other by means of a linear step actuator (17).

摘要： Directional drilling equipment comprises a drill string with a hollow bottom rod (13) connected to a boring tool (11) by means of an obtuse-angle connection piece or "bent sub" (12). In order to restore the verticality of the drilling a vertical borehole section (F) is formed and then a probe (14) equipped with an inclinometer is lowered inside the bottom rod (13). The string is rotated into four angular positions and the inclination values of the probe in each angular position are detected at the depth reached. The string is rotated so as to bring it into an angular position corresponding to the maximum inclination value detected. The string is moved so as to move the boring tool further downwards and the inclination of the probe is detected again in order to check that the verticality has been reached.

摘要： The head (10) includes an outer cylindrical body (12) with at least one upper inlet (16) for fluids, at least one outlet side nozzle (11) and at least one helical duct (13) having a helical central line (m). The duct connects the upper inlet (16) to the nozzle (11) and imparts the fluid flowing through it a helical motion about the longitudinal axis (Z) of the outer body (12) towards the nozzle (11). The helical duct (13) is progressively tapered towards the nozzle (11) and includes a terminal length of the duct which is radiused to the nozzle in a tapered manner, both when viewed in cross-sectional planes (P) parallel to the longitudinal axis (Z) and tangent to the helical central line, as well as when viewed in cross-sectional planes perpendicular to the longitudinal axis (Z).
