Wherein, flexibly hinged between cope plate and lower template, by the up fold of cope plate, waterstop can be carried out It clamps, meanwhile, cutting is inserted into corresponding first limit hole and the second limit hole, is realized between cope plate and lower template It further reinforces, so as to carry out reliable grip, moreover, the fixture block of thrust step and the card slot of waterstop to waterstop It is matched, realizes being reliably connected for thrust step and waterstop;To realize the reliable placement of waterstop, its hair is prevented Phenomena such as raw sliding, improve the reliability of fixing device.
Preferably, the inner wall of the card slot is set there are two limiting slot, and the both sides of fixture block are all provided with there are one ripple pearl screw, two Ripple pearl screw is corresponded and is matched with two limiting slots, in order to further be limited to waterstop and thrust step, ripple pearl Screw is matched with limiting slot, so as to be further fixed to the two.
Preferably, the bottom of the lower template is equipped with three connecting plates, and such lower template can reliably connect with lining cutting end It connects.
Preferably, the height of the thrust step is more than the thickness of waterstop.
Preferably, the cope plate is the L-shaped punching block in cross section, and the lower template is the punching block that cross section is in inverted L shape, Such design is used to avoid fabricating to realize the concrete for blocking lining cutting end using very thick steel plate, to advantageous In the weight for mitigating cope plate and lower template.
The utility model has the beneficial effects that:In the tunnel in buried water stop fixing device, pass through cope plate and lower die It is flexibly hinged between plate, by the up fold of cope plate, waterstop can be clamped, meanwhile, cutting is inserted into correspondence The first limit hole and the second limit hole in, realize the further reinforcing between cope plate and lower template, so as to only Water band carries out reliable grip, and moreover, the fixture block of thrust step is matched with the card slot of waterstop, realizes thrust step With being reliably connected for waterstop;Phenomena such as to realize the reliable placement of waterstop, prevent it from sliding, improve fixation The reliability of device.
