Abstract
The utility model discloses a three-dimensional composite drain board which comprises a frame formed by steel bars, a warp-weft knitting fabric layer and a non-woven fabric layer, wherein the surface of the frame made of the steel bars is covered with the warp-weft knitting fabric layer, the warp-weft knitting fabric layer is wrapped by the non-woven fabric layer, the inside of the frame made of the steel bars is sequentially filled with a gravel layer, a silt layer, a limestone layer and an activated carbon layer from top to bottom, and the warp-weft knitting fabric layer is formed in the mode that polyester fiber warp yarn and nylon fiber weft yarn are knitted to form plains. The three-dimensional composite drain board is high in reliability and long in service life, has the functions of purifying water quality and facilitating rain seepage and also is capable of effectively adsorbing poisonous gas produced by refuse landfills.
Description
Technical field
The utility model relates to a kind of surface coverage the band drain of longitude and latitude base fabric, relate in particular to a kind of can purification, the three-dimensional composite water draining board of filtered water, long service life.
Background technology
In garbage loading embeading place, because general household garbage is after rotting, all can produce a lot of noxious materials.If these noxious materials are not handled well, near the water source will polluting, particularly in rainy season, the rubbish in garbage loading embeading place, after rainwater is drenched, if can not timely and effectively filter out these noxious materials, just more pollutes the environment.So the pad system that special leakproof detoxification purifies water generally all can be set in garbage loading embeading place, pad system is mainly in order to prevent that the rainwater in garbage loading embeading place or other water are directly penetrated in underground water or in the environment of periphery.In the time that the rainwater in rainy season is a lot, in order to guarantee the safety of refuse landfill, our pad system must have guide function, therefore must diafiltration guide system be installed to liner system.Traditional diafiltration guide system generally adopts the rainwater diafiltration guide of the free drainage materials such as sand gravel for refuse landfill, can take very large landfill space.For slope percolate guide, use sand gravel will be difficult to stack simultaneously.Meanwhile, this system can not be removed the noxious material in water in time, can not remove the toxic gas that household garbage produces.And then cause the ecological deterioration around of garbage loading embeading place.The deterioration of surrounding environment, causes garbage loading embeading place vegetation around destroyed, and then causes soil erosion, may cause the gravel of the diafiltration guide system of setting up while setting up refuse landfill originally to run off, thereby does not have the effect of guide, enters vicious circle.A kind of new constructional materials of market in urgent need is manufactured the rainwater diafiltration guide system in garbage loading embeading place.
Summary of the invention
In order to solve the problems of the prior art, the purpose of this utility model is to provide that a kind of reliability is high, long service life, has the three-dimensional composite water draining board of the toxic gas that purifies water, is beneficial to rain penetration, can also effectively adsorb refuse landfill and produce simultaneously.
For achieving the above object, the utility model is by the following technical solutions: a kind of three-dimensional composite water draining board, comprise framework, the longitude and latitude base fabric that covers steel bar framework surface that reinforcing bar forms and the nonwoven layer of wrapping up longitude and latitude base fabric, in described steel bar framework, be sequentially filled with layer of gravel, silt layer, limestone layer and active carbon layer from top to bottom, described longitude and latitude base fabric is woven to plain weave by polyster fibre warp thread and nylon fiber weft yarn and forms.
Three-dimensional composite water draining board of the present utility model adopts reinforcing bar as skeleton, forms the main framework of band drain, makes its reliability high, be difficult for falling apart, and long service life.In the time of Waste Landfill Site ground, only need to around garbage loading embeading place, all build this band drain, make it wrap the rubbish in garbage loading embeading place, just can effectively filter the noxious material producing from rubbish.Base fabric and the nonwoven layer of the surface parcel of its steel bar framework can effectively filter out the rubbish being mingled with in rainwater, while base fabric is woven into plain weave by polyster fibre and nylon fiber through longitude and latitude and forms, durable, not only there is filtration, can also play certain load-bearing effect.Utilize layer of gravel, silt layer, limestone layer and the active carbon layer of in steel bar framework, filling successively, the effect that played infiltration, guide, purifies water, removes noxious material, makes the water ejecting from garbage loading embeading place not pollute surrounding enviroment.Wherein layer of gravel and silt layer play the effect of filtration; Limestone layer plays noxious material in water, the effect of sterilization of removing; The toxic chemical substance of active carbon layer in not only can adsorbed water, also can adsorb the toxic gas producing in rubbish place.
Preferred version, the particle diameter of the gravel of described layer of gravel is 3 ~ 50 millimeters.Preferred gravel particle size can make the tightr of layer of gravel filling, is unlikely to again to permeate rainwater.Good filtration can be realized, outstanding infiltration rainwater function can be brought into play again.
Further preferred version, the granular size of the active carbon of described active carbon layer is 100 ~ 300 orders.Adopt the active carbon of this granular size, the effectively noxious material in adsorbed water, purifies and gets rid of the rainwater of coming from garbage loading embeading place.
accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the perspective view of a kind of three-dimensional composite water draining board of the utility model,
Fig. 2 is the cross section sectional structure schematic diagram of a kind of three-dimensional composite water draining board of the utility model.
the specific embodiment
As shown in Figure 1 or 2, a kind of three-dimensional composite water draining board 4, comprise framework 1, the longitude and latitude base fabric 2 that covers steel bar framework 1 surface that reinforcing bar forms and the nonwoven layer 3 of wrapping up longitude and latitude base fabric 2, in described steel bar framework 1, be sequentially filled with layer of gravel 11, silt layer 12, limestone layer 13 and active carbon layer 14 from top to bottom, 2 layers of described longitude and latitude woven cloth are woven to plain weave by polyster fibre warp thread and nylon fiber weft yarn and form.The particle diameter of the gravel of described layer of gravel 11 is 3 ~ 50 millimeters.The granular size of the active carbon of described active carbon layer 14 is 100 ~ 300 orders.Adopt the active carbon of this granular size, the effectively noxious material in adsorbed water, purifies and gets rid of the rainwater of coming from garbage loading embeading place.
