Abstract

The invention discloses a fireproof and antiriot bridge steel cable protection system which comprises an inhaul cable and a protection fireproof layer on the outer side of the inhaul cable. Multiple hoops are evenly fastened to the outer side of the protection fireproof layer at intervals in the length direction of the inhaul cable; a plurality of elastic pieces are connected to the top edge and the bottom edge of the circumference of the hoops at intervals; an outer protection layer comprises a plurality of sections of outer sealing sleeves which are arranged on the outer side of the protection fireproof layer in a sleeving manner; and an outer sealing sleeve comprises two semicircular pipes, and after the two semicircular pipes are fixed in a butt joint mode, the two ends of the two semicircular pipes are fixedly connected with the elastic pieces on the two adjacent hoops respectively. According to the device, the protection fireproof layer is fastened through the hoops, so that the stability of the protection fireproof layer is improved; the outer protection layer is directly connected to the hoops through the elastic piece, so that construction can be facilitated; and the outer protection layer has an excellent vibration effect, external violent impact force can be buffered and released, and the impact resistance is improved.

Description

technical field [0001] The invention relates to the technical field of cable-stayed bridge fire prevention and fire protection, and more specifically relates to a bridge steel cable protection system for fire prevention and riot prevention. Background technique [0002] my country began to build large cable-suspended bridges in the 1990s. During the past 30 years of operation, the incidence of accidents and disasters during the bridge construction and operation periods has also increased, causing immeasurable losses to the society. With the development of my country's economy and society, the traffic flow of bridges has increased, and the number of vehicles transporting flammable and explosive materials on bridges has also increased. As a result, there have been more and more incidents of vehicle burning and fire, and the problem of bridge fire prevention has gradually received attention. For the cable system bridge, the cable is the main load-bearing component of the bridge...
