At least a portion of the water seepage blind tube 400 is disposed on the cushion layer 230. The water seepage blind tube 400 has water permeability to be located in the cushion layer 230. The moisture quickly penetrates into the water seepage blind tube 400. Alternatively, moisture located within the water immersed blind tube 400 quickly penetrates into the underlayer 230 and further penetrates the buffered rainwater through the mat 230 to the substrate 20. In the present embodiment, the water seepage blind tube 400 is a porous plastic tube. The water seepage blind tube 400 can be in communication with an external drainage system (not shown), in which rainwater can be quickly introduced into the cushion layer 230 through the water seepage blind tube 400, and the cushion layer 230 penetrates into the base layer 220 of the honeycomb structure for storage.

Water rate.

As shown in FIG. 5, in one embodiment, the infiltration system 10 further includes a watering assembly 500. The water seepage blind tube 400 is in communication with the irrigation assembly 500 and is configured to communicate with a rainwater well (not shown in FIG. 5) provided on the substrate so that moisture located in the rainwater well can be rapidly infiltrated through the water seepage blind tube 400 and the cushion layer 230 in sequence. The moisture within the screen drum 224, or within the screen drum 224, may pass through the mat 230 and The water seepage blind tube 400 quickly penetrates into the rainwater well. In the present embodiment, the watering assembly 500 is located on the side of the water seepage blind tube 400 that is remote from the cellular roadbed 200. Moisture in the base layer 220 can also penetrate into the rainwater well 30 provided on the substrate 20 through the mat 230.

In the present embodiment, the substrate 20 is a building ceiling. Both the honeycomb roadbed 200 and the planting zone 40 are laid on the substrate 20. A plurality of capillary through holes (not shown) are formed in the irrigation pipe 510 to allow moisture located in the irrigation pipe 510 to penetrate into the soil of the planting area through the capillary through holes. Alternatively, a sprinkler head may be provided at the end of the irrigation pipe 510 to uniformly spray moisture within the irrigation pipe 510 through the sprinkler head into the planting zone.

As shown in FIG. 1, it can be seen from the direction indicated by the arrow in the figure that when the surface layer 210 has a large amount of water and does not have water permeability, moisture flows into the rainwater well 30 through a sewer or a side ditch (not shown), and the rainwater The moisture in the well 30 penetrates into the mat 230 through the seepage blind tube 400, and finally penetrates into the screen barrel 224, the base body 222, and the substrate 20 by the mat 230. As the water level in the rainwater well 30 continues to rise, the water level in the sieve drum 224 will also continuously rise, because the water storage capacity of the unit cubic base body 222 is less than the water storage capacity of the inner cavity of the unit cubic sieve drum 224, when the sieve After the inner cavity of the tub 224 is filled with water, the water level rise rate of the rainwater well 30 will increase.

When the surface layer 210 has more water and has water permeability, a part of the water flows into the rainwater well 30 through the sewer or the side ditch, and the rainwater well penetrates into the cushion layer 230 through the water seepage blind tube 400, and finally penetrates into the sieve barrel 224 by the cushion layer 230. In the base body 222 and the substrate 20, another portion of moisture penetrates directly into the screen barrel 224, the base body 222, and the substrate 20 through the surface layer 210. Since the rainwater well 30, the base body 222 of the honeycomb roadbed 200, and the sieve drum 224 all have a certain water storage capacity, the flooding pressure of the city can be alleviated. When the water level of the rainwater well 30 reaches a certain height, excess water will pass through the rainwater well 30 connected drain pipes are injected into the river.

As shown in FIG. 5, when the water level in the rainwater well (not shown) is lowered, such as when the green belt is irrigated by the rainwater well or the water in the seepage blind pipe 400, the sieve drum 224 and the base body 222 The water level inside will also decrease. It can be seen from the direction indicated by the arrow in the figure that the diameter of the water located in the sieve drum 224 penetrates into the cushion layer 230 or first penetrates into the cushion layer 230 through the base layer body 222, and the moisture in the cushion layer 230 will be Infiltrating into the water seepage blind tube 400 and the substrate 20, the moisture located in the water seepage blind pipe 400 can be quickly injected into the rainwater well 30 and the irrigation pipe 510, which can alleviate the pressure of the water source required for irrigation or cleaning the streets in the city during drought.

The above-mentioned osmosis system 10, the honeycomb roadbed 200 and the sieve drum 224 thereof are disposed in the base body 222 of the base layer 220 of the honeycomb roadbed 200, and the base body 222 and the cushion layer 230 may both have water permeability and Made of water-storing material. When the surface layer 210 has water permeability, the water on the road surface can penetrate into the base layer 220 through the surface layer 210. Since the base layer body 222 has water permeability and water storage capacity, and the main body 224a of the sieve barrel 224 is provided with a plurality of water-permeable passages. The hole 2241, the moisture located in the base body 222 is filtered into the interior of the sieve drum 224 through the through hole 2241, thereby realizing the storage of moisture by the sieve barrel 224, and greatly improving the water storage capacity of the base layer 220. Of course, the moisture in the base layer 220 and the underlayer 230 also penetrates into the substrate 20 to perform natural purification and filtration of the rainwater. The screen drum 224 is embedded in the base body 222 to ensure the support capability of the base layer 220. At the time of design, the water seepage blind pipe 400 may be laid on the cushion layer 230, and the water seepage blind pipe 400 is connected to the rainwater well 30, and the water flowing into the rainwater well 30 penetrates into the cushion layer 230 through the water seepage blind pipe 400, and then passes through the cushion layer. 230 is infiltrated into the sieve drum 224 for slow storage, which can reduce the pressure of the flood. In the case of drought, water in the seepage pipe or rainwater well 30 can be extracted for irrigation or cleaning the street. Since the honeycomb body is filled in the base body 222 by the sieve barrel 224, the earthwork used for the construction of the section of the road section can be saved, so that the construction cost of the roadbed 200 can be reduced. The above-described honeycomb roadbed 200 has the effect of a city sponge, and can better regulate the rainwater of the city.
