Abstract
The invention discloses a cable trench fireproof sealing construction method, and belongs to the field of cable trench fire prevention. The method includes the following making steps: (1) using fireproof bags to make fireproof walls at the position where a bridge enters a cable trench and at a hole of the cable trench under a power distribution cabinet; (2) cleaning up garbage and sundries to-be-sealed portions; (3) finishing and flattening fire-resisting bags, and then stacking the fire-resisting bags to form fire resisting walls from bottom to top at the to-be-sealed portions in a bricklaying mode; (4) using inorganic fire partition boards on both sides of each fire-resisting wall for clamping and sealing, and fixing the fire-resisting walls on the channel wall of the cable trench through 40*4 angle steel and expansion bolts obtained after anti-rust and fire-proof treatment; (5) using organic fireproof putty to fill and seal gaps at cable passing portions and gaps between the fire-resisting walls, and making the gaps in regular shapes. The device has the advantages of being resistant to moisture, corrosion and mouse biting, not likely to collapse and long in valid period.
Description
Technical field
The invention belongs to a kind of fire-protection construction method, specifically, more particularly to a kind of cable duct fireproof blocking construction method.
Background technology
Cable duct is emphasis guard section in transformer station's fire prevention link, and when fire occurs, the intensity of a fire can be with the circumocular sky of cable duct
Gap spreads, so strictly closure cable duct spreads along the space of surrounding, the just complete control device of conservation value, while cable duct
Closure can prevent toy from running through, it is to avoid cause short circuit accident.The causing of many substation accidents often blocks problem and there is not treatment
Good, toy goes to switch board and causes short circuit, and causes fire incident.Therefore, transformer station's outlet cable ditch fireproof blocking is excellent
It is bad particularly important.
The content of the invention
It is an object of the invention to provide a kind of cable duct fireproof blocking construction method, to overcome transformer station's closure problem in the prior art
The bad defect for being susceptible to fire incident for the treatment of.
Present invention employs following technical scheme：A kind of cable duct fireproof blocking construction method, including following operating procedure：
(1) crane span structure enter cable duct at and power distribution cabinet lower section cable duct hole fire prevention wrap (granular rock wool plantar stone) make it is anti-
Wall with flues shape, it is highly consistent with cable ditch depth, and thickness is not smaller than 300mm at least, crane span structure is intercepted completely with cable duct；
(2) cleaning out needs the rubbish and its debris of closure site；
(3) back-fire relief bag (granular rock wool vermiculite) is arranged smooth, being piled into fire resisting wall as then seemingly laying bricks from the bottom to top is needing
The position of closure.It is required that closure is closely knit, and light is loseed by offside it is defined.Pile up height concordant with conduit line；
(4) clamp is carried out with inorganic fire dividing plate in fire resisting wall both sides, and with the 40*4 angle steel processed by antirust fireproof and swollen
It is swollen to be bolted on conduit line wall；
(5) cable is filled closure, and make regular shape by the gap between place and fire resisting wall with organic fire prevention calking.
Compared with prior art, beneficial effects of the present invention：The conduit line of fireproof blocking of the present invention have it is moistureproof, corrosion-resistant,
Be not afraid of damaged by rats, be difficult to cave in, the characteristics of the term of validity is long.
Specific embodiment
With reference to embodiment, the invention will be further described.
A kind of cable duct fireproof blocking construction method, including following operating procedure：
(1) crane span structure enter cable duct at and power distribution cabinet lower section cable duct hole fire prevention wrap (granular rock wool plantar stone) make it is anti-
Wall with flues shape, it is highly consistent with cable ditch depth, and thickness is not smaller than 300mm at least, crane span structure is intercepted completely with cable duct；
(2) cleaning out needs the rubbish and its debris of closure site；
(3) back-fire relief bag (granular rock wool vermiculite) is arranged smooth, being piled into fire resisting wall as then seemingly laying bricks from the bottom to top is needing
The position of closure.It is required that closure is closely knit, and light is loseed by offside it is defined.Pile up height concordant with conduit line；
(4) clamp is carried out with inorganic fire dividing plate in fire resisting wall both sides, and with the 40*4 angle steel processed by antirust fireproof and swollen
It is swollen to be bolted on conduit line wall；
(5) cable is filled closure, and make regular shape by the gap between place and fire resisting wall with organic fire prevention calking.
Claims (1)
