Description
Technical field
The invention belongs to technical field of tunnel construction, be specifically related to the construction method of a kind of tunnel fire proofing coating.
Background technology
In general, the fire hazard occurred in tunnel is very big, and in tunnel, best-effort path is limited, and fire fighter is difficult
Rescue in time with entrance scene of fire, affected by these unfavorable factors, once breaking out of fire in tunnel, often make
Become great casualties and structural failure.
For the generation of fire is reduced or avoided, need decoration and fire prevention at tunnel inner wall.Under normal circumstances, there are 3 kinds of fire prevention
Decorating method: one is to use fireproof coating brushing internal face, and this mode is common in the tunnel inner wall of highway, and its advantage is
Construction is simple, low cost, but also has serious defect, i.e. sprayed surface the most coarse, dust easy to stick and cleaning difficulty；Two is to adopt
By ceramic tile dress patch, this mode is common in urban road tunnel inner wall, and its advantage is neat appearance, can rinse, but is constructed into
This height, time permanent ceramic tile can come off, and have potential safety hazard；Three is to use PLASTIC LAMINATED decoration, and this mode needs at tunnel arch
Interior installation Os Draconis, then block-by-block installs PLASTIC LAMINATED on Os Draconis, although relatively ceramic tile safety, but difficulty of construction is big, construction cost is same
Height, and the possibility that also PLASTIC LAMINATED is damaged in operation uses.
Using fireproof coating brushing internal face is the most extensive in engineer applied and most economical effective method.It is used
Fire-proof coating for tunnels combines oneself requirement on the basis of finishing fire retardant paint and grows up, thus the research of raw material and choosing
With referring to finishing fire retardant paint.Fire-proof coating for tunnels is as sapecial coating, except having the decoration function of common coating
There is provided outside physical protection with to cable base material, in addition it is also necessary to having the specific function of flame-retardant, this just requires that they are at a constant temperature
The lower formation fire proof heat-insulation layer that can foam of degree.Therefore its base material is had a particular/special requirement, it is desirable to base material can be with whole coating system
Consonance, makes the existing good mechanical physics and chemistry function of coating, can form preferable insulated foam coating, in order to reach one again when by fire
The fixed flame-retardant time, it is desirable to foaming layer does not falls off the most yet.Additionally cable rubber type of material is high-elastic gonosome, and
And cable needs usually to check movement, this just requires that coating should have the function of enough resistance to telescopic variation, also requires that fire prevention is coated with
Expect to the rubber cable non-corrosive function of class material, adhesive force good, room temp solidified good, decorative coating film is good.
But, in the operation of daily tunnel, fire-proof coating for tunnels performance is the best, or obscission occurs, fall block etc. to tunnel
Operation causes the biggest potential safety hazard.
Summary of the invention
For the deficiencies in the prior art, the present invention provides the construction method of a kind of tunnel fire proofing coating, and the method is used
Fireproof coating there is excellent fire prevention, water resistance, and heat insulation property is good, and adhesion strength is high, it is possible to prevent coating shedding,
Fall the generation of the phenomenons such as block.
Concrete, the construction method of tunnel fire proofing coating of the present invention, comprise the following steps: tunnel structure surface is clear
Reason, sprayed fire proofing coating, steel wire arrange, flatten, spray fire resistant coating, it is characterised in that in described sprayed fire proofing coating procedure, institute
The fireproof coating used is made up of the raw material of following weight fraction ratio: refractory cement 20-35 part, styrene-acrylic emulsion 8-12 part, expansion
Perlite 8-12 part, expanded vermiculite 5-8 part, aluminium hydroxide 3-7 part, meerschaum 3-7 part, potter's clay 3-7 part, china clay 2-5 part, kaolinite
Soil 2-5 part, precipitated calcium carbonate 2-5 part, wollastonite 1-3 part, glass fibre 1-3 part, cement expansive material 0.5-1 part, concrete
Extender 0.5-1 part, cellulose ether 0.1-0.3 part, polypropylene fibre 0.1-0.3 part, rubber powder 0.05-0.1 part, alkyl naphthalene sulfonic acid
Sodium 0.05-0.1 part.
Further illustrating as the present invention, described tunnel structure removing surface includes: remove the vacation on tunnel double-lining surface
Skin, ghost, burr, carry out filling-in to construction joint, rinses the greasy dirt on tunnel double-lining surface, earth and dust.
Further illustrating as the present invention, described steel wire arranges and includes: fire resisting covering is the 1/4 of gross thickness
Time, set swell fixture, lay steel wire the most from top to bottom.
Further, described fire resistant coating gross thickness is 0.5-1.5cm.
Further illustrating as the present invention, described leveling includes: when fire resistant coating reaches design thickness, uses waterproof greasy
Zi Gua 1-2 road, polishes after drying, until surfacing.
Further illustrating as the present invention, described spray fire resistant coating includes: after leveling, selectes in inner surface of tunnel spraying
Colored paint.
Due to the fact that and tunnel structure surface is cleared up, go to degrease, imitation leather etc., fireproof coating and tunnel can be improved
The adhesion strength of two linings, makes fire resistant coating difficult drop-off.
The present invention constructs simply, and construction cost is relatively low, and is coated with fire resistant coating at outer layer, can increase inner surface of tunnel
Attractive in appearance.
Fire resistant coating of the present invention has excellent fire prevention, water resistance, and heat insulation property is good, and service life is long, through surveying
Examination, has the warranty of more than 30 years.
