A multi-impeller passive-rotating-stirring-type rotary drilling rig for open caissons includes a hollow main drill pipe, a drill bit, four cutting edges, four impeller shafts, four passive impellers and a rotation bracket. Through being uniformly distributed at a peripheral of the drilling rig, four passive impellers contact with a hole wall of a borehole during the drilling process for passively generating relative rotation opposite to the rotation direction of the drill bit, so as to accelerate sufficient mixing of silt and water for forming mud during the drilling process.

A multi-impeller passive-rotating-stirring-type rotary drilling rig for open caissons includes a hollow main drill pipe, a drill bit, four cutting edges, four impeller shafts, four passive impellers and a rotation bracket. Through being uniformly distributed at a peripheral of the drilling rig, four passive impellers contact with a hole wall of a borehole during the drilling process for passively generating relative rotation opposite to the rotation direction of the drill bit, so as to accelerate sufficient mixing of silt and water for forming mud during the drilling process, thus enhancing the stirring effect of the drill bit on the mud. The present invention is able to improve the mud discharge efficiency without adding additional power, thus avoiding the blockage of the mud suction pipe and blockage or even breakage of the drill bit due to poor mud discharge during the drilling process.

An aircraft-transportable platform component for supporting a drilling rig includes a buoyant body supported by a frame and lifting members coupled to the frame for engagement by an aircraft. A portion of the frame protrudes from an underside surface of the frame for anchoring the platform component in unstable ground. The buoyant body maintains a top surface of the aircraft-transportable platform component above the unstable ground.

A building development (1), having a building (4) arranged on a building development base (2), wherein the building development base (2) has a pontoon (8) having at least one float (6) for floating on a liquid and a pile mooring (10), which extends through a passthrough opening (14) of the pontoon (8) along a pile mooring axis (X) perpendicularly to the pontoon (8). The passthrough opening (14) is configured centrally in the pontoon (8), and the pontoon (8) is rotationally movably mounted around the pile mooring (10) that extends through the passthrough opening (14). The pontoon (8) can be aligned and positioned around a pile mooring axis (X), wherein the pile mooring (10) projects into the receiving chamber through the passthrough opening (14) of the pontoon (8) and through a first breakthrough (16) arranged in a bottom of a receiving chamber, arranged above the passthrough opening (14). The invention relates further to a building development base (2) and a pile mooring (10) of such a building development (1).
