Embodiment
The utility model is described further below in conjunction with the drawings and specific embodiments.It should be noted that this reality
It is to be directed to institute's reference with the new middle Directional terms used or determiner " on ", " under ", "left", "right", " interior ", " outer " etc.
Accompanying drawing for.They are not used to limit the absolute position of involved parts, but can change as the case may be.
It is further to note that unless explicitly stated, in category of the present utility model, " guarded drainage " " waterproof ", " row
These three terms of water " can be with general.
Fig. 1 shows the structural representation of the tunnel waterproof and water drainage system 1 according to one embodiment of the present utility model.The tunnel
Road waterproof and water drainage system 1 is particularly useful for the guarded drainage of railway tunnel.
According to the utility model, tunnel waterproof and water drainage system 1 includes arch wall water-tight device 100.In constructing tunnel, it will usually
Preliminary bracing layer 10 is usually provided with the inwall in tunnel, it is generally formed by concrete.Then, branch sheath 10 is applied in the early stage
Add according to arch wall water-tight device 100 of the present utility model.It is alternatively possible to secondary mould is set to build on arch wall water-tight device 100
Lining cutting layer 20.
Fig. 2 shows the arch wall water-tight device 100 according to one embodiment of the present utility model.As shown in Fig. 2 the arch wall
Water-tight device 100 include be applied on preliminary bracing layer 10 (Fig. 2 is not shown) from sticky cloth 110, be applied to from sticky cloth 110
Splicing tape 120, and the convex hull formula drainable waterproofing plate 130 being applied on splicing tape 120.In the illustrated embodiment, drainable waterproofing plate 130
It can be the coiled material made of PE, the projection 131 of multiple cavity-likes is provided with one surface.Two neighboring raised 131
Between be connected with each other logical formed with passage 132, each passage 132.So, arch wall water-tight device 100 can not only effectively be prevented
Water, the passage 132 that can also be introduced through carry out draining, realize the effect of " face draining ".
Fig. 3 shows the arch wall water-tight device 100 ' according to another embodiment of the present utility model.As shown in figure 3, should
Arch wall water-tight device 100 ' is roughly the same with the arch wall water-tight device 100 shown in Fig. 2, unlike, it is not used convex hull formula and prevented
Drain bar 130, but employ the splash guard 140 of ordinary flat formula.The splash guard 140 is general planar, and its surface is not set
Put projection.Therefore, it can only play a part of waterproof.In order to realize the effect of draining, splicing tape 120 is arranged only at from sticky cloth
In regional area between 110 and splash guard 140.So, the gap of adjacent splicing tape 120 can also play the effect of guiding draining
The effect of fruit, i.e. " line draining ".
By the way that according to arch wall water-tight device of the present utility model, guarded drainage effectively can be carried out to tunnel arch wall.
In constructing tunnel, because tunnel is generally very long, and laterally the size on (also referred to as ring) is also very big, therefore
Generally all it is that segmentation is constructed.Therefore, the connection between the drainable waterproofing plate (or splash guard) of each section of arch wall water-tight device 100
Place inevitably forms seam, and just there is the hidden danger of leak for this.
Therefore, seam waterproof device 200 is also included according to tunnel waterproof and water drainage system 1 of the present utility model.The seam waterproof
Device 200 can use back sticking type self-adhesion water stop band 210, buried self-adhesion water stop band 260 in can also using.
Fig. 4 shows the structure of back sticking type self-adhesion water stop band 210.As illustrated, back sticking type self-adhesion water stop band 210 includes plate
Body 205, it can for example be made up of rubber, plastics or steel plate.The first surface (bottom surface in Fig. 4) of plate body 205 is flat, and
Some fins 240 extended perpendicular to plate body 205 are provided with second surface (top surface in Fig. 4).A pair in inner side are convex
Be formed as variant part 220 between rib 240, and be formed as anchoring section 215 on the outside of variant part.Set at the middle part of variant part 220
Into generally U-shaped Drainage Division 230.The Drainage Division 230 along with the identical direction of fin 240 from the second surface of plate body 205
Stretch out, it forms fracture (i.e. the opening of U-shaped structure) at first surface, so as to form drainage channel.In anchoring section 215,
Water stop portion 245 is provided between two neighboring fin 240, it is for example made up of barrier film and adhesive polymer glue-line.Back sticking type
Self-adhesion water stop band 210 can be for example bonded on the drainable waterproofing plate (or splash guard) of arch wall water-tight device 100 by cold bonding technique, from
And prevent the seam crossing leak between two neighboring drainable waterproofing plate (or splash guard).
The structure of Fig. 5 buried self-adhesion water stop bands 260 in showing.It is similar with back sticking type self-adhesion water stop band 210, in it is buried from
Viscous waterstop 260 also includes plate body 265, extends from two surfaces of plate body 205 fin 290, be formed at inner side a pair
Variant part 270 between fin 290, and it is formed at the anchoring section 275 in the outside of variant part 270.In anchoring section 275,
Water stop portion 295 is provided between two neighboring fin 290.
In for buried self-adhesion water stop band, one part is embedded to and a part is exposed.As a rule, the part exposed
Length be about 30cm or so.The free end of this buried self-adhesion water stop band in easily causing is easily sagging in seam crossing.Therefore,
According to the utility model, 20-25cm can be shortened to by the exposed length of buried self-adhesion water stop band by, it is sagging to avoid the formation of.
Alternatively, buried self-adhesion water stop band in can also being made using steel plate, can equally be avoided the formation of sagging.Another kind solves
Scheme is to arrange reinforcement on buried self-adhesion water stop band in, overcomes the problem of sagging with this.
Furthermore, it is contemplated that the size of tunnel vertical and horizontal is all very big, it is necessary to be stitched together using multiple waterstops.
Therefore, it is also required to carry out guarded drainage between waterstop.For the adjacent waterstop extended in the same direction, heat can be passed through
Vulcanized joint (being directed to rubber fastening band), hot melting connector (being directed to plastics waterstop) and welding point (being directed to steel plate water stopper)
To realize that the guarded drainage of adjacent waterstop connects.For two waterstops extending in different directions, (such as one transversely prolonged
Stretch and one extends longitudinally) for, guarded drainage connection can be carried out by providing a geneva cross.
In addition, according to the utility model, tunnel waterproof and water drainage system 1 also includes tunnel bottom guarded drainage device 300.The anti-row in the tunnel bottom
Water installations 300 preferably may be made in a prefabricated component, and it can be prefabricated in advance at factory.So, can at job location
So that the tunnel bottom guarded drainage device 300 in the form of prefabricated component directly is installed into tunnel bottom, construction is facilitated.But need what is illustrated
