Fixing method for underground pipe gallery structure deformation joint socket steel edge water stop belt

The invention discloses an underground pipe gallery structure deformation joint socket steel edge water stop belt fixing method which comprises the steps that a shaping wooden box is manufactured, a support is erected at a deformation joint socket, and the mounting position of the shaping wooden box on the support is determined; the upper face and the lower face of the steel edge rubber water stop are connected between the two shaping wooden boxes in an abutting mode, and the shaping wooden boxes and the support are fixed; a locking device is installed in the shaping wooden box in advance, and the pre-locking position of the locking device is adjusted in the width direction of the steel-edged rubber waterstop; the end, close to the steel-edged rubber waterstop, of the locking device extends out of the shaping wooden box, so that a plurality of points on the upper face and the lower face of the steel-edged rubber waterstop are locked and fixed. By adopting the locking device, the situation that the position of
