Description
Technical field
The present invention relates to the PLASTIC LAMINATED in tunnel, relate to the technique of tunnel interior trim simultaneously.
Background technology
The tunnel inner wall of urban road tunnel and speedway all needs decoration and fire prevention.Under normal circumstances, there are 3 kinds of decorating method: one is adopt fireproof paint brushing internal face, and this mode is common in the tunnel inner wall of speedway, its advantage is that construction is simple, cost is low, but also have serious defect, namely sprayed surface is very coarse, easy binding dust is native and cleaning is difficult; Two is adopt ceramic tile dress to paste, and this mode is common in urban road tunnel inner wall, and its advantage is neat appearance, can rinses, but construction cost is high, time permanent ceramic tile can come off, and has potential safety hazard; Three is adopt PLASTIC LAMINATED decoration, and this mode needs to install keel in tunnel arch, then block-by-block installs PLASTIC LAMINATED on keel, although comparatively ceramic tile safety, difficulty of construction is large, construction cost is high equally, and also have that PLASTIC LAMINATED is damaged in operation uses may.
Having of PLASTIC LAMINATED is related to: No. ZL2004200604817 " environmental protection type composite fireproof board for tunnel " in Chinese patent application part, No. 2005100266364 " fire-proof plate for tunnel ", No. ZL200620034698X " Assembled environmental type fire-proof plate for tunnel ", No. ZL2008100716162 " a kind of fire-proof plate for tunnel and preparation method thereof ", No. ZL2008201734676 " ceramic fibre veneer fire-proof plate for tunnel ", No. ZL2009103062865 " a kind of high-tenacity waterproof and fireproof board specially used for tunnel and preparation method ", No. ZL2010105344002 " a kind of manufacture method of composite tunnel fireproof board ", No. 2012101531102 " a kind of fire-proof plate for tunnel and production technology thereof ", No. ZL201220099085X " a kind of tunnel PLASTIC LAMINATED ".Clearly, these patents are all the production technologies of fire-proof plate for tunnel.Up to now, there is no the report that the construction technology of PLASTIC LAMINATED is imitated in tunnel, also the patent application of not imitative PLASTIC LAMINATED.
Summary of the invention
The present invention aims to provide the construction technology that PLASTIC LAMINATED is imitated in a kind of tunnel, to overcome the defect of existing tunnel interior trim technique, reduces trimming cost simultaneously, for beautifying the inwall service in tunnel.
The construction technology that PLASTIC LAMINATED is imitated in the tunnel that inventor provides comprises the following steps:
(1) tunnel inner wall basic unit is cleared up
First degrease at tunnel inner wall basic unit supernatant, earth and dust, have the place of infiltration will block infiltration source;
(2) spraying bonding basic unit
Tunnel inner wall basic unit sprays with pulp shooting machine the interfacial agents tack coat of one point-like, to strengthen the adhesion stress of inwall basic unit, prevents the hidden danger of cracking, hollowing;
(3) sprayed fire proofing layer
Tunnel inner wall basic unit repeatedly sprays with pulp shooting machine the material of imitative PLASTIC LAMINATED, forms fireprotection layer;
(4) flatten
When the material of the imitative PLASTIC LAMINATED sprayed reaches design thickness, carry out pressing operation immediately, first tentatively flatten with chi bar, flatten further with plaster trowel afterwards, needing the place of mending slurry floating with smearing platen press local repair slurry again, dry whole of rear sand paper polishing, erases tool marks;
(5) levelling
Use water-proof putty for building to scrape 1 ~ 2 road, polishing after dry, until surface smoothing;
(6) sticky seam
In order to decorate, at the sticky dividing joint adhesive tape in levelling tunnel inner wall surface;
(7) color spray paint
According to design, at the color paint coating that tunnel inner wall surface spraying is selected, after spray paint completes, tear dividing joint adhesive tape off, expose dividing joint;
(8) coating hood finish paint
After colored paint drying, at the finish that tunnel inner wall surface spraying paint film is transparent, to protect the not sticky dust of colored paint, alleviate or eliminate wind sand, freezing erosion, and can wash by water.
In (2) step of above-mentioned technique, described interfacial agents tack coat is the material by common refractory and water-soluble resin mix, and the ratio that wherein refractory material and water-soluble resin are mixed is 1: 0.75, and its adhesion strength is greater than 0.15MPa.
In (3) step of above-mentioned technique, the material of described imitative PLASTIC LAMINATED by first component and second component according to 1: 1 the material that is made into of mass ratio, wherein first component is common thicker fire proofing material, second component be 1: 3 cement mortar add the compound of the Admixture of its quality 8%.The object adding cement mortar is the intensity increasing imitative PLASTIC LAMINATED.The amount that the material of PLASTIC LAMINATED is imitated in described each spraying is no more than 5mm, and the time interval of twice spraying is more than 24 hours.
In (4) step of above-mentioned technique, described chi bar is the aluminium alloys chi bar of 1m length.
In (6) step of above-mentioned technique, the lattice of described sticky dividing joint adhesive tape, the width of every lattice is 1.0 ~ 1.5m, dividing joint tape width 2cm.
