[0027] The sponge square water absorption and recovery structure provided by the present invention comprises a soil base 100, a water-permeable layer 200 laid on the soil base 100, a plurality of brick plates 300 laid on the water-permeable layer 200, and a water collecting box 800. The brick plates 300 are provided with through holes extending vertically, and a rubber cylinder 400 is embedded in the through hole. The rubber cylinder 400 has a cylinder cavity 401 extending vertically;

[0028] A plurality of diaphragms 500 are arranged in the barrel cavity 401, and the plurality of diaphragms 500 are arranged around the circumference of the barrel cavity 401. The barrel cavity 401 has a water accumulation section located above the plurality of diaphragms 500. The outer side of the diaphragms 500 is butted against the inner side wall of the barrel cavity 401, and the inner side of the diaphragms 500 is extended toward the middle of the barrel cavity 401. When the plurality of diaphragms 500 are in a horizontal state, the plurality of diaphragms 500 close the through cavity, and when the plurality of diaphragms 500 are in a bent state, the barrel cavity 401 is opened.

[0029] The water-permeable layer 200 is provided with a plurality of water collecting channels 210, which are connected to the water collecting box 800 through a pipe 220, and a water pump is provided in the pipe 220; the brick plate 300 has a plate surface arranged upward, and a plurality of water guide grooves 301 are provided on the plate surface, and the plurality of water guide grooves 301 are connected to the through hole;

[0030] The water on the plate surface enters the water accumulation section through the water guide groove 301. When the water level in the water accumulation section is set to a high level, the multiple diaphragms 500 bend downward, the cylinder cavity 401 opens, and the water in the water accumulation section enters the permeable layer 200, and enters the water collection channel 210 in the permeable layer 200, and is pumped into the water collection tank 800 by the water pump through the pipeline 220.

[0031] The sponge square water absorption and recovery structure provided above allows water to enter the water accumulation section through the diversion groove or the through hole. When the water level in the water accumulation section reaches a certain height, under the action of gravity, the water in the water accumulation section causes the diaphragm 500 to deform, and the water enters the water collection channel 210, so that the water in the water accumulation section can be effectively controlled and guided, so that the water can enter the pipeline 220 through the water collection channel 210, and the water is pumped into the water collection tank 800 by a water pump for irrigation of plants, etc. This helps to drain water, avoid the formation of accumulated water that erodes the road structure, and realize rainwater collection.

In this way, it is ensured that the water on the board surface can flow into the through hole.

[0033] The periphery of the brick plate 300 has a peripheral wall, and a water-permeable filling layer 600 is provided between the peripheral walls of adjacent brick plates 300.

The groove strip 601 extends along the length direction of the peripheral wall, and the bottom of the groove strip 601 is in communication with the water guide groove 301. In this way, multi-directional rapid drainage is achieved.

[0034] The lower part of the rubber cylinder 400 penetrates into the water-permeable layer 200 to form a lower section, which is located above the water collection channel 210; a plurality of membranes 500 are arranged in the lower section. In this way, the connection between the brick plate 300 and the water-permeable layer 200 is strengthened, and the depth of the water accumulation section is lengthened, so as to realize a large amount of water storage and drainage.

[0035] The upper part of the lower section is arranged longitudinally to form a longitudinal section 410, and a plurality of membranes 500 are arranged in the longitudinal section 410; the lower part of the lower section is arranged transversely to form a transverse section 420, and a plurality of lateral water-permeable holes 421 are arranged on the periphery of the transverse section 420. In this way, the water in the permeable layer 200 can enter the cylinder cavity 401 through the lateral water-permeable holes 421, and then enter the water collection channel 210 through the cylinder cavity 401.

[0036] A lower waterproof layer 700 is laid between the permeable layer 200 and the soil base 100, and the lower waterproof layer 700 limits the water in the permeable layer 200 from penetrating into the soil base 100. In this way, water is prevented from penetrating into the soil base 100 to damage the soil base 100.

[0037] The lower part of the water collecting channel 210 is coated with a bottom waterproof layer, which limits the water in the water collecting channel 210 from penetrating downwards, and the upper part of the water collecting channel 210 is open. In this way, the water in the water collecting channel 210 is effectively limited from penetrating downwards by the bottom waterproof layer, ensuring the water storage of the water collecting tank 800.

[0038] The water collecting box 800 is provided with a filter layer 810, a water inlet cavity is formed between the filter layer 810 and the bottom of the water collecting box 800, a water inlet cavity is formed between the filter layer 810 and the top of the water collecting box 800, and the pipe 220 is connected to the water inlet cavity; when the water in the water inlet cavity flows over the filter layer 810 from bottom to top, the water is filtered by the filter layer 810 to form clean water placed in the water inlet cavity. In this way, large particles of impurities are precipitated in the water inlet cavity by the filter layer 810.

[0039] In this embodiment, the through hole forms a top opening on the board surface, and the top opening is covered with an elastic membrane layer 900, and the elastic membrane layer 900 has a bottom surface arranged toward the through hole; a suspended column 910 arranged in the air is connected to the center position of the bottom surface, and the top of the suspended column 910 is butted at the center position of the bottom surface, and the bottom of the suspended column 910 extends downward to the top of the plurality of membrane sheets 500, and is arranged in the air;

[0040] The elastic membrane layer 900 is provided with peripheral holes 901 on its periphery, and the density of the material of the suspended column 910 is less than the density of the water body; when the suspended column 910 is in a naturally suspended state, the elastic membrane layer 900 is affected by the gravity of the suspended column 910 and is arranged to be concave downward, and the aperture of the peripheral hole 901 is reduced. When the water in the water accumulation section overflows the bottom set height of the suspended column 910, the suspended column 910 is affected by the buoyancy and pushes upward, driving the elastic membrane layer 900 to arch upward, and the aperture of the peripheral hole 901 is increased. In this way, through the design of the peripheral holes 901, a larger deformation space is provided for the elastic membrane layer 900, and its deformation is utilized; the suspended column 910 is used to realize the up and down floating of the elastic membrane layer 900, so as to avoid the water accumulation section from being blocked. In addition, through the design of the elastic membrane layer 900, it is prevented that larger impurities enter the barrel cavity 401, causing the water accumulation section to be blocked.

[0041] A plurality of elastic strips 920 are arranged around the top of the suspended column 910, and the plurality of elastic strips 920 are arranged around the periphery of the suspended column 910 at intervals; the top of the elastic strip 920 is butted against the bottom surface of the elastic film layer 900, and the bottom of the elastic strip 920 is butted against the periphery of the suspended column 910; the bottom of the suspended column 910 expands outward to form a disc-shaped bottom plate 911. In this way, through the design of the plurality of elastic strips 920, during the floating process of the suspended column 910, the deformation range of the elastic film layer 900 can be limited under the buffering effect of the elastic strips 920, and the elastic film layer 900 can be prevented from being excessively stretched or compressed during the floating process, while increasing the stability of the structure, and through the design of the bottom plate 911, the stirring area is enlarged to prevent the water accumulation section from being blocked.
