Description
Technical field
The invention belongs to plumbing fields, and in particular to one kind draining blind pipe with multi-layer structure and its component.
Background technology
It is a kind of multifunctional soil chemical product to drain blind pipe, and with light-weight, easily cutting, construction and installation are conveniently, main to use
It seeps water in collecting in casting, to reduce groundwater pressure, excludes excessive moisture, protect the soil body and building will not be because generating infiltration
It deforms and destroys.The material of existing draining blind pipe is mainly plastics and steel, for example, patent CN1556289A propose it is compound
Spring reinforcing line is made with steel wire in formula integrate draining blind pipe, sleave formula tube wall be the plastic wire squeezed out with extruding machine and at
Upset when type.It is impossible to meet the actual needs of railway construction for the draining blind pipe of the prior art.
Railway tunnel is usually built in Yushan Hill body or underground, underground integrate draining engineering undertake a greater amount of drainage loads；And
And railway tunnel draining contain more calcium salts and magnesium salts at branch, corrosivity is stronger.Steel are not corrosion-resistant materials, are added
The stress impact of upper repetitive vibrations is not used to the integrate draining engineering of railway tunnel.On the other hand, because tunnel is logical for vehicle
Row, draining blind pipe need the mechanical strength of bigger.
Invention content
Place in view of the shortcomings of the prior art, the present invention propose a kind of draining blind pipe and its component.
Second object of the present invention is to propose the application of the draining blind pipe and its component.
Realize that the technical solution of above-mentioned purpose of the present invention is：
A kind of draining blind pipe and its component, the draining blind pipe is anti-caking crystal coating from inside to outside, inner wall drainage blanket, outer
The multilayered structure that wall construction layer and filter layer are formed, drain blind pipe between connected by component.
The inner wall drainage blanket is molded by the raw material of following mass parts：High density polyethylene (HDPE) (HDPE) 80-86, cyclopentadienyl
Metal polyethylene 2~4, antiaging agent 0.1-0.2,0.5-1.0 parts of antioxidant, 2-3 parts of fire-retardant master granule, 2-3 parts of color masterbatch.
The outer wall construction layer is molded by the raw material of following mass parts：55-70 parts of low density polyethylene (LDPE), high density
15-25 parts of polyethylene, 4-5 parts of ethylene-vinyl acetate copolymer (EVA), 0.1-0.2 parts of antiaging agent, antioxidant 0.5-
1.0 parts, 2-3 parts of fire-retardant master granule, 40-50 parts of filler, 5-7 parts of silicon-calcium-magnesium whisker, 10-15 parts of reinforcing agent, 1-2 parts of color masterbatch；
Wherein, the antioxidant is antioxidant 3114, antioxidant 1010, BHT, one kind in antioxidant 1076 or two
Kind.The filler is wood powder and/or calcium carbonate, and the antiaging agent is antiaging agent RD or DNP；The outer wall and inner wall
Color masterbatch is different color.
Reinforcing agent is improving the mechanical property of tubing.The present invention provides a kind of optimal technical scheme of reinforcing agent, described
Reinforcing agent is by following mass parts at being grouped as：20-30 parts of 10-15 parts of high density polyethylene (HDPE), alkali-free glass fiber (i.e. alkali-free glasss
Fiber, the low glass fibre of alkali metal oxide content.The content of alkali metal oxide no more than 0.8%), superfine talcum powder
20-30 parts, it is 10-12 parts of ABS high glue powders, 4-6 parts of paraffin, 10-15 parts of graphene oxide, 0.8-1.0 parts of silane coupling agent, hard
10-15 parts of resin acid 1-2 roots, elastomer POE.
By the different formula design of novel inside and outside wall, the filler material and multiple additives added in outer wall formula can
The ring stiffness of tubing, the mechanical properties such as ring flexibility are effectively improved, while being added to the flame retardant property that fire retardant improves tubing；It is logical
Crossing weatherability of the improvement to inner wall formula to the smoothness of inner wall of tubing and tubing, there has also been greatly improve.
Preferably, anti-caking crystal coating is applied in inner wall drainage blanket, anti-caking crystal coating is that hydrophobic material applies to be formed, by
Phenolic resin, inorganic silicon materials, organosilicon material and metal composite high molecular material composition, it is poly- according to inner wall raw material middle-high density
Ethylene 80-86 mass parts meters, hydrophobic material dosage are 2-3 parts.
Existing hydrophobic material ingredient includes phenolic resin, nano silicon dioxide, organosilicon material, metal composite macromolecule
Material etc..For railway tunnel drainage system, calcium carbonate crystal caused by underground water is the principal element for reducing draining tube lifetime；
It prevents calcium carbonate crystal may be used and reduces the consideration of surface adhesion force direction.Calcium carbonate crystal is a slow process, crystallization-
Chemical balance between dissolving is related with the surface adhesion force of inside pipe wall.After calcium carbonate nucleus or crystallite are formed, it can be adsorbed in
Surface continues to grow up, and crystallization area is increasing.The inner wall smooth of double-wall corrugated pipe does not have lines, after being coated with hydrophobic coating, shape
At hydrophobic material layer surface adhesion force it is small, flow will take away calcium carbonate crystal ingredient, to will not form crystallization deposition
The phenomenon that, effectively prevent calcium carbonate crystal.
It is highly preferred that the outer wall of the draining blind pipe has double wave peak structure, it is disposed in the axial direction of outer wall outside 3~6
Wall reinforcing rib.Outer wall reinforcing rib can be stainless steel or polyethylene material same with outer wall.
It is less than the small-bore pipe of 200mm for diameter, (inside and outside wall all punches) is punched on tube wall；The hole is located at dual waves
The trough of structure.
Further land used, is less than diameter the small-bore pipe of 200mm, and punching form is to make a call to 2~5 every 1 or 2 wave crest
The elongate holes of a long 0.5~2cm, wide 0.1~0.5cm.
The double-wall corrugated pipe draining blind pipe diameter can be 50~800mm diameters.For a diameter of 200~600mm
The large-diameter pipe of (be free of 200mm) does not punch on the wall of the draining blind pipe；Pass through the additional clip of spigot-and-socket between large-aperture pipe
Form connection.It is less than the small-bore pipe of 200mm (containing 200mm) for diameter, connecting sleeve pair two is used between draining blind pipe
Pipe carries out straight line connection or connects three pipes with threeway or connected to two effective bend pipes at a right angle.Wherein, it is used to connect draining
The component of blind pipe includes bend pipe, connecting sleeve and threeway, and inwardly protruded platform is arranged at intervals on the tube wall of component, platform
Spacing and size are matched with the wave crest shape on outer wall construction layer, the intermediate position internal diameter contracting on the connecting sleeve length direction
