The invention discloses a fireproof and anti-explosion inhaul cable which comprises a cable body, a first fireproof layer, a second fireproof layer, a steel pipe, a waterproof cover and an anti-explosion pipe. The two ends of the fireproof cover are connected with the steel pipe and one end of the anti-explosion pipe correspondingly, and the other end of the anti-explosion pipe is connected with abridge. The cable body sequentially penetrates through the anti-explosion pipe and the waterproof cover and stretches into the steel pipe. The first fireproof layer located above the waterproof coveris arranged between the cable body and the steel pipe. The second fireproof layer located below the waterproof cover is arranged on the surface of the cable body. According to the fireproof and anti-explosion inhaul cable, on the basis of not changing the original functions of the inhaul cable, the fireproof and anti-explosion functions are provided for the inhaul cable at the same time, a protection layer and the inhaul cable are separated, meanwhile, the fireproof layers and an anti-explosion layer are also separated, and replacement and maintenance are convenient; and the fireproof and anti-explosion inhaul cable can be used for new bridge or old bridge inhaul cable construction and can also be used as the inhaul cable of a long-distance cable-stayed bridge.
Description
technical field [0001] The invention relates to a cable, in particular to a fireproof and explosion-proof cable. Background technique [0002] At present, bridge accidents mostly occur in the damage of cables caused by fire or explosion, and there is no corresponding technical means for the safety protection of cables at the same time for fire and explosion. [0003] Existing cable protection is dedicated to corrosion, vibration, etc., or the cable is only a kind of fireproof or explosion-proof function. For example, Chinese patent CN207259963U discloses a fireproof cable, which includes a cable, an inner liner, a fireproof layer and The outer liner is provided with a fireproof layer between the inner liner and the outer liner; the fireproof layer is one of filled fireproof materials, wrapped fireproof fillers or fireproof coatings, and the cable only has a fireproof function. Chinese patent CN208395669U discloses a new type of anti-explosion impact cable, including a cable...
