Abstract
A kind of tunnel fastening tape type geotextiles, for double-decker, one layer is first geotechnique's layer of cloth that fine-denier chemical fibre is made through nonwovens process, and this layer can play filtration, draining, protective action；Second geotechnique's layer of cloth that another layer is made through nonwovens process for thick denier chemical fibre, described second geotechnique layer of cloth surface forms abundant cast matte or hook-type matte through special needling process, this abundant cast matte or hook-type matte can bond with magic tape, hang fixing such that it is able to have the splash guard of magic tape, draining board and drainable waterproofing plate to realize adhesive type paving by described geotextiles and surface recombination.Convenient construction of the present invention, the splash guard, draining board and the drainable waterproofing plate paving that match hang close and firm, without unsettled space, and splash guard, draining board or drainable waterproofing plate are not caused damage, it is ensured that the installation effect of anchor bar of waterproof plate in tunnels, draining board and drainable waterproofing plate and guarded drainage effect thereof.
Description
Technical field
The present invention relates to tunnel water handling Material Field, particularly relate to a kind of can be compounded with the splash guard of magic tape, row
Water plate and drainable waterproofing plate realize the tunnel geotextiles that adhesive type is fixing.
Background technology
In prior art, the fixed form of splash guard, draining board and drainable waterproofing plate in tunnel is: as it is shown in figure 1, first
With hot melt packing ring and nailing, geotechnique's layer of cloth is fixed in the preliminary bracing in tunnel, then by splash guard, draining board or guarded drainage
Plate sweat soldering is on hot melt packing ring.This paving is hung fixed form and is had the disadvantage that: 1) need to use artificial one by one at hot melt pad
Place carries out sweat soldering, and efficiency of construction is low；2) splash guard, draining board or drainable waterproofing plate are easy to crack at sweat soldering, at cracking
Seepage easily occurs, and the guarded drainage effect of splash guard, draining board or drainable waterproofing plate is difficult to ensure that；3) during tunnel tunnel face blast working
Can produce impact air-flow, the breach of gas shock splash guard, draining board or drainable waterproofing plate easily causes splash guard, draining board or anti-row
Water plate destroys further and even drops.
Summary of the invention
It is an object of the invention to provide a kind of tunnel fastening tape type geotextiles, thus solve present in prior art
Foregoing problems.
To achieve these goals, the technical solution used in the present invention is as follows: a kind of tunnel fastening tape type geotextiles, should
Geotextiles is double-decker, and one layer is first geotechnique's layer of cloth that fine-denier chemical fibre is made through nonwovens process；Another layer is thick
Second geotechnique's layer of cloth that denier chemical fibre is made through nonwovens process, described second geotechnique layer of cloth surface is through special needling process shape
Become abundant cast matte or hook-type matte.
Preferably, the line density of described first geotechnique's layer of cloth is 2-6 denier.
Preferably, the line density of described second geotechnique's layer of cloth is 6-30 denier.
Wherein, the described abundant cast matte on the second geotechnique layer of cloth surface is 2 with the peel strength of Hook of thread gluing strap bonding
～30N/cm.
Wherein, the described abundant hook-type matte on the second geotechnique layer of cloth surface is 2 with the peel strength of thread gluing zone circle face bonding
～30N/cm.
Further, it is characterised in that abundant cast matte or the hook-type matte of described second geotechnique's layer of cloth are acupuncture work
Skill is made.
Wherein, the physical and mechanical property of described geotextiles meets TZ 331-2009 " railway tunnel guarded drainage construction technology refers to
South " in about the technology requirement of cushioning layer material geotextiles, i.e. described in following table:
The invention has the beneficial effects as follows:
One layer of the present invention is first geotechnique's layer of cloth that fine count fiber is made through nonwovens process, and this layer can play
Filter, draining, protective action；Second geotechnique's layer of cloth that another layer is made through nonwovens process for coarse denier fiber, described second geotechnique
Layer of cloth surface forms abundant cast matte or hook-type matte through special needling process, and this abundant cast matte or hook-type matte can be with
Magic tape bonds, such that it is able to have the splash guard of magic tape, draining board or drainable waterproofing plate by described geotextiles and surface recombination
Realize paving and hang fixing.Fastening tape type bonding paving hangs convenient construction, splash guard, draining board or drainable waterproofing plate paving close and firm；This
Invention need not splash guard, draining board or drainable waterproofing plate be welded with hot melt pad, on splash guard, draining board or drainable waterproofing plate not
There will be hot melt breaking point.
