A system for supporting and transporting a drilling rig. The system may have a pair of rails, wherein each rail has a plurality of rail segments and a plurality of connections between the segments. Moreover, each connection may have a plurality of interlocking lugs secured with a shear pin and opposing abutment faces, such that each connection may be configured to transfer moment and shear forces between adjacent rail segments. In some embodiments, the each rail segment may be configured to support a point load of up to 1000 kips. In some embodiments, each rail segment may have a protruding connector and a receiving connector, and each connection may include the protruding connector of a first segment and the receiving connector of a second segment. In some embodiments, a portion of each connection may be configured for tension loading and another portion may be configured for compression loading.

A side saddle slingshot drilling rig includes a right substructure and a left substructure, the substructures positioned generally parallel and spaced apart from each other. The right substructure includes a right lower box and a first strut, the first strut pivotably coupled to the drill rig floor and pivotably coupled to the right lower box. The left substructure includes a left lower box and a second strut, the second strut pivotably coupled to the drill rig floor and pivotably coupled to the left lower box. The side saddle slingshot drilling rig also includes a drill rig floor, the drill rig floor including a V-door. The side of the drill rig floor has the V-door defining the V-door side of the drill rig floor, the V-door side of the drill rig floor parallel to the right substructure. The side saddle slingshot drilling rig further includes a mast, the mast including an open side defining a mast V-door side. The open side is oriented to face perpendicular to the right substructure. The mast is pivotably coupled to the drill rig floor by one or more mast pivot points and one or more lower mast attachment points, the mast being pivotable in a direction parallel to the V-door side of the drill rig floor or the mast being pivotable in a direction perpendicular to V-door side of the drill rig floor. The mast includes two or more subunits, wherein the two or more subunits are pinned together.

There is provided a utility pole assembly including a utility pole. The utility pole includes a plurality of pole segments. A first said pole segment includes a flange and an end portion extending outwards from the flange. A second said pole segment is shaped to fit about the end portion. The second said pole segment having a distal end and including a flange adjacent to said distal end of the second said pole segment. The assembly includes at least one longitudinally-extending guide pin connectable with a first one of the flanges. The guide pin is at least partially extendable through a second one of the flanges.

Tower erecting systems and methods are disclosed. An example method for erecting a tower includes: nesting frusto-conical tower sections within one another and within a frusto-conical tower base; securing the frusto-conical tower base to a tower foundation; lifting each frusto-conical tower section from within the frusto-conical tower base with a lifting apparatus; and securing each frusto-conical tower section to the frusto-conical tower base or to a previously lifted frusto-conical tower section.

The invention relates to a method for erecting a structure 0 comprising at least two prefabricated concrete elements 1, 2, the method comprising: installing a first concrete element 1; placing a second concrete element 2 with at least one spacer 4 maintaining a gap between respective end faces 104, 203 of the first element and second element; tensioning at least one bar 105, 3 held on the first and second elements and passing through the gap maintained by the spacer, and introducing a hardenable interface product 5 into said gap. The method thus makes it possible to move off the critical path relating to the erection the need to wait, between two assembly operations, for the joints between the assembled pieces to have hardened. Incidentally, a significant reduction in the time taken for erecting such a structure is obtained.
