In the anti-impact flame-retardant barrier, the upper end of the elastic corrugated pipe is fixedly connected with a sealing ring, and the sealing ring is connected with the elastic corrugated pipe in a sliding and sealing manner.

In the anti-impact flame-retardant isolation fence, the movable plate is sleeved with the elastic cloth, the lower end of the elastic cloth is fixedly connected with the upper end of the base, and the outer surface of the elastic cloth is embedded with the water-absorbing fiber layer.

Compared with the prior art, the anti-impact flame-retardant isolation fence has the advantages that:

1. the invention can counteract the impact from the outside by arranging the spring and the elastic corrugated pipe, reduce the impact force to the vehicle and the like and reduce the damage to the vehicle and the isolation fence.

2. By arranging the supporting pipe, the invention can automatically spray water when the elastic corrugated pipe deforms due to impact, thereby reducing the probability of spontaneous combustion of the vehicle due to impact and reducing accident loss.

3. By arranging the memory spring, when the temperature is too high in summer and reaches the stretching temperature of the memory spring, the spring automatically shrinks to extrude water in the elastic corrugated pipe, so that the temperature of the road surface around the isolation fence is reduced.

4. According to the invention, by arranging the elastic cloth and the water absorption fiber layer, when the water spraying sleeve sprays water, the water absorption fiber layer is used for absorbing water and locking water, when the memory spring is reduced to be below the expansion temperature and suddenly recovers to a long time, the elastic cloth shakes, water drops on the water absorption fiber layer shake off, and the air around the isolation fence is sprayed with water again for cooling.
