Function of cable trench blocking device
The cable trench blocking device is fireproof and anti-small animals, and a cable trench blocking device is installed every 100 meters in the cable trench. The fireproof blocking partition utilizes the cable support frames on both sides of the cable trench to fill the cable gaps with organic blocking materials, the spare part is sealed with fire-resistant packaging, and the middle channel is separated by bricks, concrete and mortar. After the bricks are laid, the passage will be blocked forever. When the cables are to be repaired and replaced, the partitions need to be destroyed, which makes repairing and replacing the cables very inconvenient.
The technical problem to be solved by the cable trench blocking device is to provide a cable trench fire-proof blocking partition so that maintenance personnel can pass through when repairing the cable.
The technical scheme of the cable trench blocking device includes the use of cable support frames, organic blocking materials covering the cable gaps, fire bags for filling and sealing the remaining space, and fire door components. The feature is that the fire doors are installed in the middle of the cable support frames on both sides , The door frames on both sides of the fire door are respectively fixedly connected with the cross bars of the cable support frame on both sides, and the vertical bars of the cable support frame are fixedly connected with the ribs embedded on both sides of the cable trench.
