Disclosed is an apparatus (100) for sub-surface injection of constituents of a slurry, wet mixture, and or gas in a phase of entrainment for controlled flow. The apparatus (100) includes a rotary union (113), a drilling assembly (403), hollow shaft injection drilling arrays (1003A), limit switches (1705, 1707, 1709), and encoders (1605B). The rotary union (113) facilitates the filling of the constituent in hollow shaft drilling bits (129) during a drilling process or before the drilling process via an opening and closing of a plurality of valves (111, 215, 505B, 805B, and 1107B). The constituents are capable of being injected through the rotary union, wherein the rotary union (113) is in concert with the valve (111) to dispense predefined quantities of constituents at a specific depth in a sequence of dispersal. The drilling assembly (403) is directed by a GPS (1413C) to control an X plane and Y-plane injection coordinates. The drilling assembly (403) determines through a PLC (1405C), a computer (1411C), and an AI robot (1505) in concert with achieved depths of the Z (cubic) volume of injected material. The hollow shaft injection drilling arrays (1003A) provide the sequential dispensing of the constituents at one or more targeted depths, wherein the hollow shaft injection drilling arrays (1003A) enable capturing of targeted volumes of constituents thereby creating mono or poly constituent horizons. The hollow shaft injection drilling arrays (1003A) are enabled by the limit switches (1705, 1707, 1709), the encoders (1605B), and the AI robot (1505) to sequence the constituents to be injected at specific depths.

Construction equipment is provided that can include: a transport assembly operably supporting a platform, the platform having a leading edge opposing a rearward edge, the leading edge associated with a first direction of the transport assembly, and the rearward edge associated with a second direction of the transportation assembly; an operator cab above the platform and aligned closer to the leading edge than the rearward edge; an engine above the platform and aligned closer to the rearward edge than the leading edge; and a boom pivotably attached above the platform closer to the rearward edge than the leading edge, the boom being movable between a first position fully extended and a second position fully raised. Utility line pole placement and/or removal construction methods are provided that can include extending an extension assembly having a banana boom from a transport assembly to couple with a utility line pole.

A guide device and associated methods for forming a hole in the ground using compression or other means. In one example, the guide device includes a compression hammer having a hammer tip; a guide frame member for guiding the compression hammer into one or more positions along the guide frame member; and a movement control assembly securing the compression hammer to the guide frame, the movement control assembly selectively moving said compression hammer along said guide frame, so that said compression hammer forms the hole in the ground. By compressing soil materials, which has the effect of increasing soil density around the hole, a more rigid and accurate hole (i.e., within higher dimensional tolerances) is created when compared with holes created by drilling/boring/excavation.
