The invention discloses a temporary rapid installing support for cable erection. The temporary rapid installing support for cable erection comprises a square-arch-shaped frame body, inclined pull wires, ground anchors, hydraulic cylinders, a multi-way valve and a hydraulic station, wherein the inclined pull wires are connected with the top corners of the square-arch-shaped frame body and are fixed to the ground through the ground anchors, and the hydraulic cylinders are arranged between the inclined pull wires and the ground anchors 3 and are connected with the hydraulic station through the multi-way valve. The pull force of each pull wire can be independently controlled, it is only required that the pull wires and the ground anchors are connected together through the hydraulic cylinders and the hydraulic cylinders are controlled by the multi-way valve to stretch or contract to adjust the pull force of the pull wires, and the whole temporary rapid installing support for cable erection is easy, convenient and fast to install, high in corresponding speed and accurate in pull force control.
