A kind of self-adhering type insulation spill guide
Technical field
The utility model relates to tunnel water handling technical fields, and in particular to a kind of self-adhering type insulation spill guide.
Background technique
The cold-proof freeze proof measure of extremely frigid zones railway tunnel waterproof and water drainage system is always that great in Concerning Railway Tunnel Construction is asked
It inscribes, it is main that the position 1.2m other than preliminary bracing is mounted on using circumferential blind pipe in existing tunnel in cold area waterproof and drainage design, and facing upward
The scheme in center gutter is connected under arch in the form of traverse furrow, make tunnel vault draining it is unobstructed, this scheme not only time and effort consuming,
Project amount is huge, causes security risk, and does not have heat preservation to drainpipe at all in the concrete of dead season 1.5m left and right thickness
Effect, vault still seeps water seriously, by frost heave, so that vault construction is become fragile, the diseases such as concrete cracking, chip off-falling occur
Evil.
A kind of self-adhesive waterproof plate is disclosed in the file of Publication No. CN206785410U, passes through self-adhesive layer and tunnel
The buffer layer bonding that preliminary bracing surface paving is hung is realized that the paving of splash guard ontology is hung and is fixed.But its thermal insulation property is poor, does not have
Standby cold-proof cryoprotective effects, have much room for improvement.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of self-adhering type insulation spill guide, and which solve tradition
The poor defect of self-adhesive waterproof plate thermal insulation property.
Technical problem to be solved in the utility model is realized using following technical scheme:
A kind of self-adhering type insulation spill guide, including from sticky cloth, vacuum heat-insulating plate and self-adhesive waterproof plate, it is described from sticky cloth and
Self-adhesive waterproof plate is wrapped in the two sides of vacuum heat-insulating plate respectively.
Further improvement lies in that being connected with several self-adhesive tapes, self-adhering type by hot melt adhesive on the self-adhesive waterproof plate
Splash guard is Nian Jie with vacuum heat-insulating plate by hot melt adhesive, and self-adhesive tape faces outwardly.
Further improvement lies in that the core material of the vacuum heat-insulating plate is powder core material or glass core material.
Further improvement lies in that being filled with metal getter in the core material of the vacuum heat-insulating plate.
Further improvement lies in that the metal getter is powder structure.
The beneficial effects of the utility model are: by using self-adhering type insulation spill guide, so that railway tunnel guarded drainage system
The good heat insulating of system ensure that the guarded drainage of tunnel in cold area vault is unobstructed, and reduce difficulty of construction, reduce work
Amount.

Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
In conjunction with shown in Fig. 1 to Fig. 3, a kind of self-adhering type insulation spill guide, including from sticky cloth 1, vacuum heat-insulating plate 2 and self-adhering type
Splash guard 3 is wrapped in the two sides of vacuum heat-insulating plate 2 from sticky cloth 1 and self-adhesive waterproof plate 3 respectively.In addition, self-adhesive waterproof plate
Several self-adhesive tapes 31 are connected with by hot melt adhesive on 3, self-adhesive waterproof plate 3 is Nian Jie with vacuum heat-insulating plate 2 by hot melt adhesive, from
Adhesive tape 31 faces outwardly.
Wherein, the material of self-adhesive waterproof plate 3 is low-pressure high-density polyethylene (density 0.910-0.925g/cm3), polyphenyl
One of ethylene, ethylene-vinyl acetate copolymer or phenolic resin.
Wherein, the core material of vacuum heat-insulating plate 2 is powder core material or glass core material, and is filled out in the core material of vacuum heat-insulating plate 2
Filled with metal getter, metal getter is powder structure, material be selected from for K, Ca, Na, Mg, Al, Zn or Fe one kind or
It is a variety of.
As shown in figure 4, showing the paving hanging method of above-mentioned self-adhering type insulation spill guide, first in tunnel surrounding 100
200 upper berth of preliminary bracing hangs bonding layer from sticky cloth 300, then by above-mentioned self-adhering type insulation spill guide 400 (including from sticky cloth 1, vacuum
Heat-insulating shield 2 and self-adhesive waterproof plate 3) self-adhesive waterproof plate side be pasted onto and need the position that keeps the temperature, finally protected in self-adhering type
Outer layer self-adhesive waterproof plate 500 is hung in spreading from sticky cloth side for warm splash guard 400.
