Over time, wind loading on insufficiently braced utility poles has caused utility pole tipping, resulting in the weight of the conductor failing the line. In some environments, such as soft soils, guy wires may be ineffective in bracing utility poles. Traditional methods of supporting a utility pole include using one or more guy wires at the upper end of the utility pole to laterally brace the upper end of the utility pole in the vertical position. Utility poles are used to support overhead power lines and other public utilities. This document relates to methods and apparatuses of supporting and bracing a utility pole. This application is a continuation-in-part of U.S. A combination comprising: a bracket comprising a plate and a clamp a utility pole extended from a ground surface, in which the plate is secured to the utility pole a screw pile fastened to the clamp and penetrating the ground surface along an axis that is parallel to a utility pole axis and a lateral stabilizer connected to the utility pole in which the utility pole is positioned above or partially within unstable soil, and the unstable soil is one or more of permafrost, soils with ice lensing, muskeg, soil with organics, water saturated soils, silts, sands, peat, hog fuel, wood chips, and weak alluvial soils. The combination of claim 11 further comprising a screw pile thrust stop secured to the plate.Ģ0. The combination of claim 17 in which the clamp defines a screw pile shaft axis, which is parallel to a utility pole axis defined by the channel.ġ9. The combination of claim 11 in which the utility pole mount is a channel formed by the plate and having a C-shaped cross-sectional shape.ġ8. The combination of claim 11 in which at least one of the cooperating screw pile shaft receiving parts is fused to the plate.ġ7. The combination of claim 14 in which the second screw pile comprises plural second screw piles secured at various radially spaced locations about a utility pole circumference.ġ6. The combination of claim 11 in which the screw pile is a first screw pile, and further comprising a second screw pile penetrating the ground surface and secured by bracket to the utility pole at a base of the utility pole above the ground in a batter pile configuration relative to the utility pole, in which the first screw pile is mounted parallel to a utility pole axis.ġ5. The combination of claim 11 in which the utility pole is positioned above or partially within unstable soil that is one or more of permafrost, soils with ice lensing, muskeg, soil with organics, water saturated soils, silts, sands, peat, hog fuel, wood chips, and weak alluvial soils.ġ4. The combination of claim 11 in which bolts securing the bracket to the utility pole or fastening the screw pile to the clamp are installed to an installation torque at or above 150 Newton meters.ġ3. A combination comprising: the bracket of claim 1 a utility pole extended from a ground surface, in which the plate is bolted to the utility pole through the bolt holes in the plate and a screw pile fastened to the clamp and penetrating the ground surface.ġ2. The bracket of claim 9 in which the screw pile thrust stop comprises a plate positioned across a screw pile shaft axis defined by the clamp.ġ1. The bracket of claim 1 further comprising a screw pile thrust stop secured to the plate.ġ0. The bracket of claim 1 in which the clamp comprises a series of clamps axially aligned and spaced from one another along the plate.ĩ. The bracket of claim 5 in which each stiffener comprises a utility pole penetrating pin.Ĩ. The bracket of claim 5 in which each stiffener has a utility pole contacting edge that is curved to follow a portion of an outer circumferential surface of a utility pole.ħ. The bracket of claim 3 further comprising a series of stiffeners located within the channel.Ħ. The bracket of claim 3 in which the clamp defines a screw pile shaft axis, which is parallel to a utility pole axis defined by the channel.ĥ. The bracket of claim 1 in which the utility pole mount is a channel formed by the plate and having a C-shaped cross-sectional shape.Ĥ. The bracket of claim 1 in which at least one of the cooperating screw pile shaft receiving parts is fused to the plate.ģ. A bracket comprising: a plate having bolt holes and a utility pole mount and a clamp secured to the plate, the clamp comprising cooperating screw pile shaft receiving parts having laterally extending flanges, the flanges having fastener receiving openings for securing the clamp around a screw pile.Ģ. The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:ġ.
