Abstract
The present invention relates to the water baffle system comprising barrier rib, for preventing material to the flowing of the side of the wall, wherein the barrier rib includes fabric, the fabric can prevent the infiltration of the fluid of the material and comprising high-strength polyolefin fiber.
Description
Technical field
The present invention relates to the baffle system comprising barrier rib, it is used for preventing material to the flowing of the side of the wall, its
Described in barrier rib include fabric.
Background technology
This baffle system is well known in the art, such as from US 4033137, it is disclosed that being used for accommodating
The obstruct of oiliness leakage or other debris on the surface of water body.The obstruct can also include flat rectangular slab, the square
Shape plate can be constituted by stretching in the impermeable fabric in rectangular shaped rim.
The content of the invention
However, known baffle system (such as presented above) can improve according to observations.Therefore, target of the invention
The baffle system of improvement can be to provide and the obstruct system with suitable strength and/or mechanical stability is more specifically provided
System.
The present invention provides the baffle system comprising barrier rib, for preventing material to the flowing of the side of the wall, wherein
The barrier rib includes fabric, and the fabric can prevent the infiltration of the fluid of the material and comprising high-strength polyolefin fibre
Dimension.
It has been observed that baffle system of the invention can prevent relative bulkrage (dust, rock, water, snow etc.
Deng) flowing, and fault-free.Additionally, it has been observed that baffle system of the invention can maintain its original-shape, though temperature,
Under the change of temperature and other environmental factors.Specifically, even if running into by material (such as those discussed above) miscarriage institute
Raw multiple loads, baffle system of the invention can still maintain its original-shape.
Specific embodiment
In one embodiment, baffle system of the invention be used for preventing such as rock burst apart or snowslide in occur
The flowing of rock or snow.Fabric for manufacturing the barrier rib of the system of the implementation method needs to prevent flowing and the snow of rock
Flowing, but it is probably favourable some rocks or some wachtes is crossed rock wall for the reason for energy loss.This can be with
Realized by using the fabric wherein with opening.
In another embodiment, baffle system of the invention is used for preventing the flowing of dust.
In further embodiment, baffle system of the invention is water baffle system, i.e., for preventing the flowing of water

Embodiment and contrast experiment
Embodiment
It is 0.193kg/m with AD2, thickness about 0.6mm, about 1.72 meters of width and comprising 880 dtex be referred to asThe basket braided fabric of the polyethylene yarn of SK 65 prepares barrier rib, the fabric impregnated of
0203。0203 is the plastic body from DEXPlastomers, and is have about 18% octane, density for 902kg/
m3And DSC Peak melting points are 95 DEG C of vinyl octane plastic body.Plastic body is melted and flowed out at a temperature of about 145 DEG C
On the surface of fabric.
Apply the pressure of about 45bars, so that plastic body is impregnated into fabric at about 120 DEG C.
In order to coat two surfaces of woven fabric, said process is repeated.The barrier rib for being obtained has the thickness of about 0.8mm
Degree, 0.550kg/m2AD and the space less than 40%.The AD of wall is that the AD280% of woven fabric is high.Plastomer layer is designed
Into：
● one surface A D about 0.17kg/m of covering2Part I；
● Part II of the dipping through fabric between its yarn and fiber；
● another surface A D of covering is for about 0.175kg/m2Part III.
