Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-4 is please referred to, the present invention provides a kind of technical solution: a kind of preformed armouring shield lines, including it is arranged in bridge
The cable of beam or tunnel portal, the cable include clue 1 and the armour protective layer 2 that is coated in 1 axial direction of clue, the armour
Dress protective layer 2 further includes that sheath 21, intermediate flame-retardant layer 23 and outer jacket 22, the intermediate flame-retardant layer 23 are located at the interior shield
Between layer 21 and the outer jacket 22, the sheath 21 is coated along the axial direction of the clue 1, and the outer jacket 22 is coated on institute
