Abstract
The utility model relates to a drainage permeation-resistant board which is composed of a nonwoven fabric infiltration filter layer and a concave-convex waterproof basal board. Nonwoven fabric and the waterproof basal board are polymerized, and are bonded into a whole with the waterproof basal board through the convex surface of the waterproof basal board. A drainage passage is formed between the concave-convex of the waterproof basal board and the nonwoven fabric infiltration filter layer. The board can be buried in a foundation soil layer when civil engineering construction is carried out, so that excessive formation water can penetrate through the nonwoven fabric to be drained outward from the drainage passage. The waterproof basal board has the functions of water isolation and permeation resistance. The utility model can prevent the water from leaking towards a working surface, and can be used for the permeation resistance of the drainage of the foundation of civil engineering, such as roads, foundation structure, tunnel culvert buildings, etc.
Description
The utility model relates to a kind of draining barrier sheet, and it is to be embedded in a kind of in the underground foundations such as highway, railway, sports ground, building, tunnel to have draining antiseepage materials with function.
As everyone knows, in the more area of rainwater, because rich groundwater, the ground of civil workss such as the ground of highway, railway, sports ground and building, subterranean tunnel all need have good drainage, in case heavy rain later contains dilutional hyponatremia in the stratum, cause the ground humidity, even ground is loosening caves in; Especially also should there be seepage control measure in building and tunnel, in order to avoid the infiltration of underground flooring is moist, seepage is dripped in the tunnel, and influence is normally used.At present, porous blind pipe and the plastic plates of adopting are realized the draining antiseepage more in the civil works.Blind pipe is wrapped with chemical fibre non-woven fabric, and water infiltrates in the porous blind pipe from adhesive-bonded fabric in the stratum, discharges by blind pipe.Plastic plate be placed on as required blind pipe above or below.The used blind pipe of this method is many, complex structure, and it is big to bury workload underground, and is the point type contact, and the infiltration area is little, and drainability is relatively poor, the cost height.
The purpose of this utility model provides a kind of draining barrier sheet, and it integrates draining, antiseepage function, and is simple in structure, buries underground conveniently, and the draining anti-seepage effect is good.
The utility model draining barrier sheet is made up of adhesive-bonded fabric permeatable filter layer and concave-convex type waterproof substrate, adhesive-bonded fabric and waterproof superimposed substrate, the adhesive-bonded fabric permeable formation is integral by the convex surface and the waterproof substrate bonding of waterproof substrate, forms drainage channel between the convex-concave surface of waterproof substrate and the adhesive-bonded fabric permeatable filter layer.The plastics book plate that said waterproof substrate can be a surface irregularity in the heat ductile forming process, is compound in adhesive-bonded fabric its surface while hot, and both are bonded into one.
The utility model draining barrier sheet has permeable and the antiseepage function, can when civil engineering, it be imbedded in the foundation soil, when the dilutional hyponatremia of stratum, hydrostatic pressure increases in the soil, water is under pressure action, see through adhesive-bonded fabric enter its with the plastics waterproofing substrate between passage in, from the outside draining of this passage, avoid foundation soil to become flexible and the consequence that causes ground to cave in.The plastics waterproofing substrate has the antiseepage effect, can prevent that sealing is to the work plane seepage.The utility model can be put in order the plate large tracts of land and bury underground, easy construction, and the saving of labor economizes material, saves cost.Be applicable to the draining water proof of occasions such as highway, railway, sports ground, structure foundation and tunnel culvert, can avoid especially basement metope, sweat get damp and the tunnel culvert in the infiltration dripping phenomenon.
Below in conjunction with description of drawings example structure of the present utility model.
Fig. 1 is the structural representation of this draining barrier sheet.
Fig. 2 is an embodiment three-dimensional structure diagram of concave-convex type waterproof substrate.
Fig. 3 is the use-case schematic diagram that this draining barrier sheet is applied to road foundation.
Fig. 4 is the use-case schematic diagram that this draining barrier sheet is applied to building basement.
Fig. 5 is the use-case schematic diagram that this draining barrier sheet is used for the tunnel culvert.
As shown in Figure 1, the upper strata of this draining barrier sheet is the strong chemical fibre non-woven fabric permeatable filter layer 1 of water permeability, and lower floor's waterproof substrate 2 is high-intensity concave-convex type plastics book plates (its structure is seen Fig. 2), flexible distortion, chemical fibre non-woven fabric 1 is bonding with each convex surface of waterproof substrate 2, and the two is combined into one.Space between the male and fomale(M﹠F) of adhesive-bonded fabric 1 and waterproof substrate 2 forms drainage channel, and the arrow of Fig. 1 both sides is represented the situation that water is discharged from passage.Fig. 2 is a structure embodiment of draining substrate 2, and as shown in Figure 2, concave surface 2-2 and convex surface 2-1 are contained in the surface of this waterproof substrate, and concave surface and convex surface intersect alternately, and it is excessive to be cambered surface between the two, forms drainage channel.In Fig. 3 example, this draining barrier sheet is embedded in the soil layer under the ground 3 of road, and waterproof substrate 2 is downward, its below be stratum soil 5 ', adhesive-bonded fabric 1 upwards its top has soil layer 5 again.The avenue tree that 4 expression both sides, road surface are planted among the figure.When rainwater from surface flow during to the soil, both sides, the water such as the direction of arrow are infiltrated soil layer 5 downwards, and discharge by the concavo-convex passage that adhesive-bonded fabric 1 infiltrates waterproof substrate 2.Stratum soil 5 ' interior moisture is intercepted by plastics waterproofing substrate 2 and can not permeate to roadbed 3, thereby guarantees the firm safety of roadbed.This draining barrier sheet is used to prevent that the embodiment of building basement infiltration from seeing Fig. 4, and plastics waterproofing substrate 2 is towards the ground 7 of basement 6, and adhesive-bonded fabric 1 guarantees that towards soil layer 5 basement metope and ground drying do not seep water.The embodiment that this draining barrier sheet is used for the tunnel culvert sees Fig. 5, and it is embedded in the outside soil layer of culvert along the curved surface bending of culvert 8, and waterproof substrate 1 is towards the culvert side, and the adhesive-bonded fabric pervious layer prevents that towards soil layer 5 tunnel railway or highway tunnel inwall and end face from seeping water in the hole.
