Emergency restoration structure

A restoration structure is recommended as a temporary replacement to assure rapid restoration in an emergency event. The modular structure provides a method to rapidly restore safe operation of a transmission line while a permanent replacement is in the engineering and procurement process. The modular structure provides an `erector set´ at full scale with interlocking units standardized. Each unit is labeled with its exact weight. No unit exceeds 600 lb. A user-friendly PC program is used to determine structure strength by guy tensions and anchor locations. After selection of the structure type the program asks for several inputs at the structure location. Structure height, guy slope, load parameters, factors, etc. are inputs. Computer program output gives guy tension and checks comprehensive loads. The user determines if computed tensions are viable for the chosen guy/anchor system and modifies the program to suit the parameters and chosen guy/anchor system. With the results of the design program for a given structure type, the user determines a layout for the structure foundation and the required anchors. Field operations and the erection method for the structure are discussed
