Abstract
The utility model belongs to the technical field of the waterproof material of using of building stagnant water, a waterproof board, drain bar or prevent drain bar that is used for between tunnel preliminary bracing and the secondary lining is disclosed. Its technical scheme comprises with the plastic substrate who connects in between the convex hull a plurality of convex hulls, and both structures as an organic whole, combination department of base plate and convex hull is arc or chamfer structure. The uncompacted problem of concrete filling in convex hull and plastic substrate's combination department stress concentration and the convex hull is solved to the panel of this structure.
Description
Technical field
This utility model relates to tunnel support component technology field, can be used for railway tunnel, highway tunnel particularly to one
Splash guard, draining board or drainable waterproofing plate between road or the preliminary bracing of municipal tunnel and secondary lining.
Background technology
The complicated railway tunnel waterproof and drainage design in tunnel, especially geological state follow " prevent, arrange, cut, bridging conjunction, because of ground
Suiting measures to different conditions, comprehensive control " principle build.On the one hand the waterproof requirement of function, Tunnel and two are used for meeting tunnel
Splash guard is all laid between secondary lining cutting；Simultaneously for discharging secondary lining subsoil water behind, it is to avoid or reduce hydraulic pressure to lining cutting knot
The detrimental effect of structure, typically lays draining board between Tunnel and secondary lining.Fig. 1 is used by prior art
The structural representation of draining board, i.e. this draining board are made up of some convex hulls 1 and the plastic base 2 being connected between convex hull, convex hull with
The junction 3 of plastic base uses right angle transitional structure.The subject matter that this draining board structure in use exists is:
One, when draining board tension, convex hull is easily generated problem of stress concentration with the junction, right angle of plastic base, and then causes combining
Place's fracture；Its two, in concreting process, junction, right angle is unfavorable for the flowing of concrete, concrete in convex hull easily occurs
Filling uncompacted problem, convex hull is yielding by preliminary bracing extruding so that the cross dimensions of drainage channel reduces, and then impact
The drainability of draining board also increases secondary lining water pressure behind, increases the security risk of structure.
Utility model content
This utility model solve purpose be just to provide one effectively prevent stress collection neutralize enable in convex hull
A kind of splash guard, draining board or the drainable waterproofing plate that Concrete Filled is closely knit.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of splash guard, draining board or drainable waterproofing plate, be made up of some convex hulls and the plastic base being connected between convex hull, and
Both are structure as a whole；It is characterized in that: the junction of described substrate and convex hull is arc or chamfering structure.
Its additional technical feature is:
Described convex hull is dome-type；
Described convex hull is the hollow structure of top seal；
Described plastic base is connected with the bottom of described convex hull；
Described plastic base is connected with the arc pars intermedia of described convex hull.
A kind of splash guard, draining board or the drainable waterproofing plate that this utility model provides, compared with prior art has following excellent
Point: one, the junction of described substrate and convex hull owing to constituting this plate is arc or chamfering structure, solves convex hull and plastics
The junction stress of substrate is concentrated and the uncompacted problem of Concrete Filled in convex hull；Its two, due to plastic base and convex hull
Arc pars intermedia connects so that its base plate bottom has in some lining cutting being inserted in second coagulation soil, substantially increases
Splash guard, draining board or drainable waterproofing plate and the bonding strength of secondary lining.
Accompanying drawing explanation
Fig. 1 is existing draining board structural representation.
Splash guard, draining board or the drainable waterproofing plate structural representation that Fig. 2 provides for this utility model；
Fig. 3 is the second splash guard, draining board or drainable waterproofing plate structural representation.
Detailed description of the invention
The structure of a kind of splash guard, draining board or the drainable waterproofing plate that below in conjunction with the accompanying drawings this utility model are proposed do into
One step explanation.
As in figure 2 it is shown, be the structural representation of splash guard, draining board or drainable waterproofing plate, its structure and embodiment include indulging
To and be laterally made up of some convex hulls 1 and the plastic base 2 being connected between convex hull respectively, and both are structure as a whole, and base
The junction 3 of plate and convex hull is arc (or chamfering) structure so that formed by the junction 3 of concrete arc in casting process
It is beneficial to the flowing of concrete, and flows in convex hull smoothly, form closely knit concrete 4；The junction of this arc is favourable simultaneously
The stress herein of eliminating concentrate the generation causing brisement phenomenon occurs, also overcome convex hull by preliminary bracing extruding easily simultaneously
The cross dimensions deforming, making drainage channel reduces and then affects the drainability of draining board and increase secondary lining behind
The appearance of water pressure phenomenon.
Constitute in the structure of above-mentioned splash guard, draining board or drainable waterproofing plate:
When above-mentioned convex hull is dome-type structure, not only preparation technology is simple, more importantly due to its convex hull 1
Highly increase and plastic base 2 and the prolongation intersection of the junction of convex hull are that rectangular-shaped (i.e. plastic base extended line 9 is through half
The centre of sphere of ball-type convex hull), therefore can be greatly improved the comprcssive strength of sheet material；
Above-mentioned convex hull 1 is the hollow structure that top 5 is closed, and plastic base 2 and the end of convex hull 1 as shown in Figure 2
Portion connects；
Additionally as it is shown on figure 3, when plastic base 2 is connected with the arc pars intermedia 6 of convex hull so that the bottom of substrate
Just defining annular ring 7, this annular ring is inserted in the lining cutting in second coagulation soil, substantially increases splash guard, draining board
Or the bonding strength of drainable waterproofing plate and secondary lining；This annular ring and the junction 8 of plastic base are in beneficially concrete simultaneously
The arcuate structure of flowing.
