All other embodiments obtained by a person skilled in the art without making any inventive step, based on the given embodiments, fall within the scope of protection of the present application.
In the description of the present application, it is to be understood that the terms "upper", "lower", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.
In the description of the present application, the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.
The utility model discloses ecological porous cellucotton 100 capable of slowly releasing rainwater, which comprises a rock wool fiber body 1, wherein a transversely-unfolded barrier material layer 2 is arranged in the rock wool fiber body 1, a channel 3 for rainwater to pass through is formed on the outer side of the barrier material layer 2, and as shown in figure 1, the edge of the barrier material layer 2 is away from the edge of the rock wool fiber body by a distance 31. The slow release effect can be influenced by adjusting the distance.
In this embodiment, the rock wool fiber body 1 is a block structure made of rock wool fibers, and may be called porous fibers because of the inherent properties of rock wool fibers.
Referring to fig. 1 and 2, the barrier material layer 2 may be made of a film material, which may be a hard plastic film or a soft plastic film. As shown in the drawing, in one embodiment, the rock wool fiber body 1 is cut and then a film material is placed in the rock wool fiber body 1, and the film material is spread in a plane and transverse direction in the rock wool fiber body 1, thereby forming a structure in which the barrier material layer 2 is spread in a transverse direction in the rock wool fiber body 1.
As shown in the figure, the rock wool fiber body 1 is largely divided into upper and lower layered structures by a membrane material. It can be understood that, because of the structure of the membrane material, after the rock wool fiber bodies of the upper layer and the lower layer are separated by the membrane material, the inherent capillary water absorption process of the rock wool fiber is interrupted to a certain extent, and the rainwater adsorbed by the rock wool fiber body 11 of the upper layer is prevented from permeating and transferring to the rock wool fiber body 12 of the lower layer to a certain extent, so that the volume water content of the rock wool fiber body 1 can be kept at a relatively high value after the rock wool fiber body is placed for a plurality of times.
Generally, the film material has a plurality of layers, and the plurality of layers of the film material are arranged at intervals in the height direction of the rock wool fiber body 1. In this embodiment, the plurality of layers of the film material may be spaced apart by a distance of 5-25 cm. Of course, the spacing distance between the layers of the film material may take other values to achieve different water retention.
In one embodiment, the rock wool fiber body 1 has a length, width and height dimension of 12.2m x 0.3m x 0.5m, and the rock wool fiber body 1 has a volume water content of 96.1% after being filled with water, and is substantially stable at about 30% after half an hour of slow-release permeation. The following experimental data were obtained using the following different spacing distances to insert a film material having a length and width dimension of 1.0m by 0.2 m:
and adding a layer of membrane material every 10cm, and after half an hour of slow-release permeation, increasing the volume water content from 30% to 70%.
And a layer of membrane material is added every 15cm, and after half an hour of slow-release permeation, the volume water content is improved from 30% to 60%.
And a layer of membrane material is added every 25cm, and after half an hour of slow-release permeation, the volume water content is increased from 30% to 50%.
In another embodiment, through holes 30 may be provided in the membrane material to accommodate the root growth needs of the plant. Rainwater on the rock wool fiber body 1 on the upper layer can permeate into the rock wool fiber body 1 on the lower layer through the through holes 30. Of course, a relatively large membrane material may be used as a whole, and rainwater contained in the upper rock wool fiber body 1 may permeate into the lower rock wool fiber body 1 only through the through holes 30.
In the present invention, the membrane material is made of a material having no water permeability.
From the data of the above examples, the volume water content is obviously improved after half an hour of penetration, so the ecological porous cellucotton has the slow release effect.
In another embodiment, through-holes 30 are provided in the layer of barrier material 2. In the present embodiment, the passage 3 through which rainwater passes is formed by the through-hole 30. The size of the through-holes 30, and the overall area of the through-holes 30, may be tailored depending on the desired volumetric water content. As an equivalent embodiment, both the channels 3 for passing rainwater are formed on the outside of the barrier material layer 2 and the channels 3 for passing rainwater are provided on the barrier material layer.
Usually, the rock wool fiber body 1 is covered with a permeable geotextile so as to be buried in the ground for use. In specific application, in a season with much rainwater, the ecological porous cellucotton 100 for slowly releasing the rainwater can fully absorb the rainwater, and after the surrounding soil is lack of water, the rainwater slowly permeates into the surrounding soil by utilizing the slow release performance of the ecological porous cellucotton 100 for slowly releasing the rainwater, so that the drought state of the soil is relieved.
In another embodiment, the membrane material may be made of waterproof paper, and may or may not be provided with the through-hole 30 structure. Of course, the membrane material may also be replaced by a grid plate.
It should be noted that the ecological porous cellucotton for slowly releasing the rainwater can adjust the volume water content, namely the gas-water ratio to be suitable for different plant growths by setting the distance of the barrier material layer and/or the diameter of the through holes on the barrier material layer and the total area of the through holes. Thus, the ecological porous cellucotton 100 for slowly releasing rainwater can be applied more.

Meanwhile, the released rainwater enters the drainage pipe 51 through the graded broken stone 61 and the second hole 502 and is discharged. The ecological porous cellucotton 100 for slowly releasing the rainwater has a filtering function, and the rainwater treated by the flower box can meet the II-class and above index requirements of the national surface water quality standard.
As shown in the drawing, the overflow pipe 53 communicates with the drain pipe 51, and the top of the overflow pipe 53 is provided with an overflow port 531, and the overflow port 531 is lower than the top of the tank 4.
