Figure 1

[0026] ​The sponge city rainwater resource utilization system mainly comprises a water storage and drainage unit, an exhaust unit, a flow guide unit, a water storage unit and a drainage unit, wherein the water storage and drainage unit has pores inside, can store the penetrated rainwater in the pores, and is naturally discharged when the amount of the stored rainwater in the pores is sufficient; the exhaust unit is used for connecting the water storage and drainage unit with the outside air, so as to avoid the air pressure difference between the inside of the water storage and drainage unit and the outside. The flow guide unit is used for connecting the inside of the water storage and drainage unit, and connecting the water storage and drainage unit with the water storage unit and the drainage unit, so that the rainwater can flow freely. The water storage unit is used for storing the rainwater flowing from the water storage and drainage unit, so as to deliver the rainwater to the drainage unit when needed. The drainage unit is used for recycling the delivered rainwater, for example, city green land irrigation, car washing, roof vegetation irrigation, etc.

[0027] In one embodiment, the water storage unit can not be provided, and the water storage and drainage unit is directly used as a temporary storage of the collected rainwater, and the rainwater is directly delivered from the water storage and drainage unit to the drainage unit through the flow guide unit.

[0028] The water storage and drainage unit is arranged on the base layer 60, and inorganic glass porous modules 10 are specifically selected, so that the water storage and drainage unit can be used without frequent cleaning and will not be corroded by rainwater in a long-term use process, even if the rainwater is mixed with impurities, the wear and tear can also be avoided, and the size can be kept stable in a large range of temperature alternation between summer and winter, so that mutual extrusion and gaps between adjacent inorganic glass materials are avoided, and the effective water storage and drainage capacity is continuously ensured. For example, the inorganic glass porous material is selected as foamed glass, and the rainwater is stored in the porous structure inside the foamed glass.

[0029] In one embodiment, the inorganic glass porous module 10 can be prepared as a whole plate and directly laid on the base layer 60. Alternatively, the inorganic glass porous module 10 can also be prepared as a plurality of blocks and laid on the base layer 60 by mutual splicing.

[0031] In one embodiment, the water storage and drainage unit further comprises a second filter layer 50, and the second filter layer 50 is arranged at the bottom of the inorganic glass porous module 10. When the rainwater stored in the inorganic glass porous module 10 penetrates downward, the rainwater can first pass through the filtering action of the second filter layer 50, so that the impurities can be prevented from penetrating into the base layer 60 below the inorganic glass porous module 10.

[0032] In one embodiment, the first filter layer and the second filter layer 50 are made of acid- and alkali-resistant filter cloth. For example, the acid- and alkali-resistant filter cloth may be a geotextile.

[0034] In one embodiment, the diversion unit is configured as a diversion tube 30. For example, one end of the diversion tube 30 is inserted into the inorganic glass porous module 10, and the other end is connected to the drainage unit, thereby allowing rainwater to flow bidirectionally between the inorganic glass porous module 10 and the drainage unit. In another embodiment, both ends of the diversion tube 30 can be inserted into different inorganic glass porous modules 10, thereby allowing rainwater to flow between adjacent inorganic glass porous modules 10. In another embodiment, the diversion tube 30 can also be used to connect the inorganic glass porous module 10 with the water storage unit, and to connect the water storage unit with the drainage unit.

[0035] In one embodiment, the water storage unit includes at least one water storage container. For example, only one water storage container may be provided, or a plurality of water storage containers may be provided in a distributed manner.
