Abstract
The present invention relates to waterproof material technical fields, title is a kind of waterproof jointing material for tunnel concrete structure seam, main technical schemes: the self-adhesive glue layer being used in conjunction with concrete surface including the substrate being made of closed cell rubber foam plate and coated on the substrate side；Wherein, closed cell rubber foam plate includes ethylene propylene diene rubber, carbon black, AC foaming agent, altax, vulcanizing agent and auxiliary blowing agent.Self-adhesive glue layer coated on closed cell rubber foam plate side when construction can be realized and the combination of new-old concrete, and that self-adhesion adhesive tape and concrete are pasted is firm, sealed waterproof effect is good, it ensure that impervious conjunction old and new concret face i.e. construction joint, stability and binding force, and the also feature simple, easy for construction, quick with process.Various new-old concrete connecting portions can be applied, there is great promotional value.
Description
Technical field
The invention belongs to traffic engineering technical fields, will specifically be related to one kind and be used in deformation joint, construction joint and stretch
The waterproof jointing material of the tunnel concrete structures such as seam seam.
Background technique
In the underground structures such as subway, the underground space, original old concrete structure exists with the concrete newly poured can not
The faying face avoided i.e. construction joint, the construction joint of tunnel lining structure, deformation joint, these gaps are then the emphasis portions of waterproofing design
Position should accomplish not leak, is not permeable, without wet stain.Since the contraction of old concrete is completed, and the contraction of novel concrete has just started,
The contraction of new-old concrete must cause to shear or stretch to form crack in faying face, not only prevent new-old concrete from being total in this way
With work, and make the problems such as infiltration, leak are generated between the new and old concrete poured, seriously affect the durable of tunnel structure with
Service performance.Railway tunnel Second Lining Construction stitches waterproofing design at present, and 300mm wide back sticking type generally is arranged in structure upstream face
Waterstop 3, and 5 watertight connection of splash guard, buried water stop 4(is shown in Fig. 1 in the setting of centre)；Secondary lining waterproofing of movement joints is set
300mm wide back-adhering waterstop 3 generally is arranged in structure upstream face, with splash guard watertight connection in meter；It is stitched in structure back side
End setting 20mm galvanized steel plain sheet water receiver 8, the two-component polysulfide rubber sealing compound 9 that 15-20mm depth is then arranged again is embedding
Seam, land side use pointing 7 to clog (see figure 1).The common processing mode of basal plane be by old concrete joint surface dabbing, with
Increase frictional force, the conjugation of contact surface, buried water stop, external labeling type waterstop improve the waterproofness of faying face and resist in setting
Infiltration property, since polysulfide sealant is influenced by execution conditions, such as cement basal plane is moist or removing surface is not in place and aging
Etc. reasons, cause falling off for polysulfide sealant.On the one hand waterproof effect is lost, the train of another aspect cast and high-speed cruising
Generation severe traffic accidents are hit, especially middle buried water stop, positioning difficulty is big, easily deviates, and causes seam crossing cracking, chip off-falling work
Cheng Zhiliang is difficult to ensure.
It is an object of the invention to provide a kind of waterproof jointing materials for tunnel concrete structure seam.
To achieve the above object, the technical solution adopted by the present invention are as follows:
A kind of waterproof jointing material for tunnel concrete structure seam, including the substrate being made of closed cell rubber foam plate and painting
It is overlying on the self-adhesive glue layer of the substrate side being used in conjunction with concrete surface；Wherein, the closed cell rubber foam plate includes
The ethylene propylene diene rubber of 100 parts by weight, the carbon black of 10-18 parts by weight, the AC foaming agent of 0.3-0.6 parts by weight, 0.3-0.5
The auxiliary blowing agent of the altax of parts by weight, the vulcanizing agent of 0.3-0.6 parts by weight and 3.0-4.5 parts by weight.
In constituting a kind of above-mentioned waterproof jointing material for tunnel concrete structure seam,
--- isolated film is covered on the surface of the self-adhesive glue layer；
--- the self-adhesive glue layer includes the butyl rubber of 100 parts by weight, the thickening filler of 8-18 parts by weight and 10-
The tackifier of 20 parts by weight, the solvent naphtha of 180-220 parts by weight, the polyisobutyl group alkene of 10-15 parts by weight；
