The invention relates to the technical field of electric power paying-off, and particularly discloses a rapid fixing type paying-off construction process. The rapid fixing type paying-off constructionprocess comprises the following steps that S1, a rapid fixing type paying-off device is taken, wherein the rapid fixing type paying-off device comprises a support and a cable installing disc, the cable installing disc is rotationally connected to the support, and the cable installing disc comprises a supporting shaft and two baffle discs which are distributed in the axial direction of the supporting shaft; S2, a cable coil is installed, wherein the cable installing disc is taken down from the support, the baffle discs are taken down from the cable installing disc, the cable coil which needs to be installed sleeves expanding rods, then the taken-down baffle discs are installed back, stretching and retracting units are adjusted, so that the inner ring of the cable coil is tightened throughthe expanding rods, the baffle discs are adjusted, so that the baffle discs tightly press against the two sides of the cable coil, and the cable installing disc are installed on the support; and S3, paying-off is prepared, wherein a cable head of the outer ring of the cable coil is sorted out, and a section of cable is pulled out for later use. According to the scheme, the problems that the cablecoil is scattered, the paying-off speed of the cable is low and the manual labor intensity is large in the prior art are solved through the cable installing disc, the stretching and retracting units and the expanding rods.
