[0039] An assembly groove 4 is formed in one of the second side plates 22 , and an assembly protrusion 5 aligned with the assembly groove 4 is formed in the other second side plate 22 .

[0040] The bottom plate 1, side plates 2 and top plate 3 are lightweight concrete components.

[0041] A chamfer 6 is formed at the transition point of the outer contour of the side panel 2 .

[0042] Specifically, the module unit can be used as a water reservoir module, an equipment module 13 , and a gray water tank module 14 .

[0043] Specifically, the bottom plate 1 and the top plate 3 are formed with assembly grooves 4 and assembly protrusions 5 corresponding to the side plates 2 .

[0044] More specifically, the assembly groove 4 and the assembly protrusion 5 in the first side panel 21 are arranged at the midline position. Similarly, the assembly groove 4 and the assembly protrusion 5 in the second side panel 22 are arranged at the midline position.

[0045] Specifically, the cross-sections of the assembly groove 4 and the assembly protrusion 5 are trapezoidal. Example

[0046] like Figure 1 As shown, a modular rainwater recycling device integrated with rail transit entrances and exits includes eight modular units, namely six water reservoir modules, an equipment module 13, and a reclaimed water tank module 14. The six water reservoir modules are a first water reservoir module 7, a second water reservoir module 8, a third water reservoir module 9, a fourth water reservoir module 10, a fifth water reservoir module 11, and a sixth water reservoir module 12.

[0047] As an assembly instruction, the first water reservoir module 7 is assembled with the second water reservoir module 8 via the assembly groove 4 and the assembly protrusion 5 on the second side panel 22, and the first water reservoir module 7 is assembled with the fourth water reservoir module 10 via the assembly groove 4 and the assembly protrusion 5 on the first side panel 21. The above assembly is repeated to form a two-row and four-column arrangement.

[0048] Specifically, two rows and four columns of modular units are arranged at the entrances and exits of rail transit.

[0049] Specifically, the chamfers 6 between the first water reservoir module 7 , the second water reservoir module 8 , the third water reservoir module 9 , and the fourth water reservoir module 10 form a strip-shaped cavity.

[0050] Specifically, a pipe network is laid out in the module unit to form a pipeline connection, such as Figure 1 As shown, the connection order is the first water tank module 7, the second water tank module 8, the third water tank module 9, the fourth water tank module 10, the fifth water tank module 11, the sixth water tank module 12, the equipment module 13, and the intermediate water tank module 14.

[0055] Specifically, the module unit is in the form of a lightweight concrete component, and the volume of each module unit is 24 cubic meters. The size and shape of the module unit can accurately match the shape and size of the foundation pit of the standard entrance and exit of the rail transit, saving the construction investment of the space excavation and support of the water collection area itself, greatly saving costs. At the same time, the module unit has a simple shape, is sturdy and durable, and the assembly groove 4 and the assembly protrusion 5 can be directly spliced with each other to form a mortise and tenon system. The overlap relationship is very tight, which is convenient for installation and fixation.

[0056] Specifically, the eight modular units have fixed water delivery directions that align with the spatial design of the ground water collection tanks and sunken green spaces. Subway entrances and exits themselves require water collection tanks, sunken green spaces, and transportation connections, and the spatial flow of these functions aligns with the water delivery direction of the modular water collection system. Therefore, the prefabricated modular units, combined with the entrance and exit enclosures and ground landscape layout, form an efficient sponge city area, effectively solving problems such as entrance and exit landscape design, disaster prevention and water diversion, and rainwater recovery.
