Abstract
The utility model belongs to the technical field of urban railway system communication engineering, and relates to a civil air defense engineering through hole fireproofing plugging system for a subway, which is characterized in that one end of the through hole is enclosed through a fire retarding block and sealed through epoxy resin putty, an inflaming retarding foam material produced through on-site foaming is filled in the middle of the through hole, and the other end of the through hole is enclosed through a hard foam material and sealed through the epoxy resin putty. The civil air defense engineering through hole fireproofing plugging system can instantly and freely foam to seal the cable-penetrating pipe hole in the construction site, and solidify in short time, so as to form high-strength rigid sealing, and the static load strength of the plugging amounts to 0.6MPa. By adopting the system, not only the pipeline sealing of the subway is accelerated, but also the shock resistance of the first civil air defense door of the five-level civil air defense is satisfied, as a result, the force resistant piece that is complicated to machine and difficult to mount is replaced.
Description
Technical field
The utility model relates to the track traffic technical field, particularly subway people's air defense through hole fireproof blocking system in the railway traffic engineering.
Background technology
Subway engineering is because the needs of operation; Each mechanical discipline is like specialties such as communication, moving photograph, FAS, BAS, guiding; All there are many cables will pass through the door frame wall in access, air channel and the partition wall between the protective unit; For guaranteeing Pyatyi people's air defense resistibility requirement, these shutoff measures of wearing the cable pore all should be satisfied its protection airtight performance.
Existing subway people's air defense shutoff engineering is still continued to use the asbestos bitumen material of early stage use, and the obstruction construction is difficult, and it is more than to distribute pernicious gas renders operation workman tear stream, can't work continuously, and causes construction speed slow, is difficult to accomplish the shutoff task of hole surplus in the of nearly ten thousand.
Summary of the invention
For this reason; To the above-mentioned material problem; The utility model proposes a kind of subway civil air defense constructions and installations through hole fireproof blocking system, solves the fireproof blocking of horizontal through hole in the subway civil air defense constructions and installations, vertical through hole, can freely foam immediately at the construction field (site) and wear the cable pore with shutoff; Solidify at short notice, form the high strength rigid seal.Said a kind of novel subway civil air defense constructions and installations through hole fireproof blocking product is characterized in that, product is a base-material with hard-foam polyurethane foaming material, and adds fire proofing and process.
Subway civil air defense constructions and installations through hole fireproof blocking system; It is characterized in that: an end of through hole seals with the back-fire relief piece, and with the sealing of epoxy resin putty, the centre is filled with the flame-retardant expanded material layer that foam-in-place generates; The other end of through hole seals with fire proofing, and seals with the epoxy resin putty.
Said flame-retardant expanded material layer is the sieve aperture shape.
Said flame-retardant expanded material is the polyurethane foam material that is added with fire retardant.
Said back-fire relief piece thickness is 50mm.
Said fire proofing is a hard flame retardant polyurethane sheet material, and its thickness is 50mm.
The utility model subway civil air defense constructions and installations through hole fireproof blocking system; In the conventional sealing of the two ends of through hole construction; Adopt the on-the-spot directly foaming material forming of foaming in the intermediate layer; Sealing with between through hole and the pipeline is more tight, and the foaming material has suitable structural strength and cohesion after solidifying.This system is to have good engineering property, and its easy construction is quick, and the tool good air-tightness.This material is easy to remove, and is convenient to run through the replacing of thing.
This system has the favorable environment protection ability, and it does not contain hazardous substancess such as formaldehyde, chlorine, bromine and heavy metal, in construction with in using human body is not had physiological harm.It also has good chemical property, can be acidproof, alkaline-resisting, oil resistant, Stability Analysis of Structures, have long application life.
This system is good seal performance not only, and the static load intensity of its obstruction can reach 0.6MPa, satisfies the requirement of civil air defense constructions and installations fully.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the vertical view of the utility model,
Each label is listed as follows among the figure:
The 1-through hole, 2-back-fire relief piece, 3-epoxy resin putty, the flame-retardant expanded material of 4-, 5-fire proofing, 6-pipeline.
The specific embodiment
As shown in the figure; Subway civil air defense constructions and installations through hole fireproof blocking system; It is characterized in that: an end of through hole 1 seals with back-fire relief piece 2, and with 3 sealings of epoxy resin putty, the centre is filled with the flame-retardant expanded material 4 that foam-in-place generates; The other end of through hole 1 seals with fire proofing 5, and with 3 sealings of epoxy resin putty.
Preferred flame-retardant expanded material 4 is for being added with the polyurethane foam material of fire retardant.
Preferred back-fire relief piece 2 thickness are 50mm.
Preferred fire proofing is a hard flame retardant polyurethane sheet material, and its thickness is 50mm.
Because through hole pipeline 6 is more, flame-retardant expanded material 4 presents the sieve aperture shape.
The utility model subway civil air defense constructions and installations through hole fireproof blocking system; In the conventional plate sealing of the two ends of through hole construction; Adopt the on-the-spot directly foaming material forming of foaming in the intermediate layer; Sealing with between through hole and the pipeline 6 is more tight, and the foaming material has suitable structural strength and cohesion after solidifying.This system is to have good engineering property, and its easy construction is quick, and the tool good air-tightness.This material is easy to remove, and is convenient to run through the replacing of thing.
Job practices:
A) earlier through hole 1 is cleaned out, removed foreign material such as dust, grease.
B) through hole one end is sealed with thick back-fire relief piece 2 fillings of 50mm, and with 3 sealings of paste epoxy resin putty.
The raw material that c) will be added with the polyurethane foam material of fire retardant (is respectively how different hydrogen acid ether (hydrogen acid ester) of many phenyl polymethine and PPG; The two is liquid material) be filled into the civil air defense constructions and installations through hole from the other end after the mixing by a certain percentage; And with the another port with the thick hard flame retardant polyurethane foaming plate of 50mm filling sealing, and with 3 sealings of paste epoxy resin putty.
D) mixed liquor begins foaming and intumescing at 10-20 in second, is full of space and slit in the through hole 1, begin in 10 minutes to solidify, and sclerosis in 30 minutes, typing has fully formed flame-retardant expanded material 4 in 2 hours.
