Deformation, to influence the drainage efficiency of drain bar.
Utility model content
The purpose of the utility model is to provide a kind of plastic draining boards, it solves the problems, such as that drain bar is easily deformed, from
And improve the drainage efficiency of drain bar.
The above-mentioned purpose of utility model of the utility model has the technical scheme that
A kind of plastic draining board, including core plate and filter membrane, the filter membrane are wrapped in the outside of core plate, the two sides of the core plate
Face is equipped with rhone, and the cross section of the core plate is in wave linear shape shape, and the core plate includes connecting plate, folded plate and convex hull, connects
The both ends of plate are fixed with folded plate, and bifoldable plate is fixed with convex hull.
By using above-mentioned technical proposal, when the underground of drain bar insertion subgrade, the sundries of membrane filtration soil layer, so that
Water under subgrade wears the rhone that more filter membranes enter drain bar, and the external drainpipe in the top of drain bar and vacuum pump are arranged
Water is drained to realize using drain bar；This drain bar structure is simple, and rationally, the design of core plate can be effective for design
The deformation of drain bar is reduced, to enhance the structural strength of drain bar, is conducive to the drainage efficiency for enhancing drain bar.
The utility model is further arranged to: the connecting plate and folded plate form 25 to 75 angles spent.
By using above-mentioned technical proposal, angle is 25 to 75 connecting plates spent and folded plate while ensureing structural strength,
The cross-sectional area of rhone is increased, to be conducive to drain bar draining.
The utility model is further arranged to: the cross section of the convex hull is arc-shaped.
By using above-mentioned technical proposal, arc-shaped convex hull makes the more compact structure of core plate, to reduce core plate
Deformation is conducive to the structural strength for enhancing core plate.
The utility model is further arranged to: the filter membrane is specially non-woven fabrics.
By using above-mentioned technical proposal, non-woven fabrics is a kind of non-woven cloth, it is directly to utilize high polymer slice, short fibre
Fiber by air-flow or mechanical networking, is then reinforced by spun lacing, needle thorn or hot rolling, finally passes through final finishing shape by dimension or long filament
At non-woven cloth.Non-woven fabrics is compared with general knitted or woven fabrics, in the case where water-permeable and air permeable performance is the same, non-woven fabrics tool
There are better toughness and tensile strength.
The utility model is further arranged to: the material of the filter membrane is terylene or polyvinyl.
By using above-mentioned technical proposal, the advantages of terylene and polyvinyl, is that wearability is good, hygroscopicity is poor, therefore can be reliable
Complete filtering, durable task in ground.
The utility model is further arranged to: the side of the filter membrane and the other side are staggeredly compound.
By using above-mentioned technical proposal, the side and the other side of filter membrane are compound by ultrasonic wave in place of interlocking, ultrasonic wave
The compound structure that will not destroy filter membrane, to ensure that filter membrane has preferable filter effect.
In conclusion the advantageous effects of the utility model are as follows:
1. the underground of this drain bar insertion subgrade, the sundries of membrane filtration soil layer, so that the water under subgrade
The rhone that more filter membranes enter drain bar is worn, the external drainpipe in the top of drain bar and vacuum pump are drained, so that realizing makes
It is drained with drain bar；This drain bar structure is simple, and rationally, the design of core plate can be effectively reduced the change of drain bar for design
Shape is conducive to the drainage efficiency for enhancing drain bar to enhance the structural strength of drain bar；
2. filter membrane is specially non-woven fabrics, non-woven fabrics is compared with general knitted or woven fabrics, in the same situation of water-permeable and air permeable performance
Under, non-woven fabrics has better toughness and tensile strength, and non-woven fabrics also has the advantages that low cost, to reduce production draining
The cost of pipe.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model.
In figure, 1, core plate；101, connecting plate；102, folded plate；103, convex hull；2, filter membrane；3, rhone.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It referring to Fig.1, is a kind of plastic draining board disclosed by the utility model, including core plate 1 and filter membrane 2, filter membrane 2 are wrapped in
The outside of core plate 1, filter membrane 2 not only acts as the effect of protection core plate 1, and filter membrane 2 can filter sundries, prevent sundries is from leaning on
Nearly core plate 1, while ensureing the drainage efficiency of drain bar, there is the phenomenon that congestion in also reduction drain bar；Filter membrane 2 is non-woven fabrics
And be made using the material of terylene or polyvinyl, not only ensure filter membrane 2 strainability, but also make filter membrane 2 it is more wear-resisting and
