[0030] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1

[0033] The following is in conjunction with the appendix Figure 1-5 This embodiment will be further described as follows:

[0034] This embodiment provides a roadbed structure 10. Please refer to [link / reference]. Figure 1-5 The roadbed structure 10 includes the roadbed body 200 and the water storage structure 100.

[0035] The water storage structure 100 is not specifically limited. In this embodiment, the water storage structure 100 includes a water storage component 110 and a water-using mechanism (not shown in the figure).

[0036] The water storage component 110 is disposed inside the roadbed body 200. In this embodiment, the water storage component 110 includes a connected water storage tank 111, at least one outlet pipe 112, and at least one collection pipe 113. In this embodiment, the water storage tank 111 is disposed in the middle of the roadbed body 200, and the collection pipe 113 is disposed above the outlet pipe 112. Both the collection pipe 113 and the outlet pipe 112 are connected to the water storage tank 111. In this embodiment, one end of the collection pipe 113 is connected to the water storage tank 111, and the other end extends toward the top of the roadbed body 200. The collection pipe 113 has multiple first collection holes 114. The above-mentioned arrangement of the collection pipe 113 is conducive to collecting rainwater over a large area from multiple directions. After the rainwater enters the collection pipe 113 through the first collection holes 114, it automatically slides into the water storage tank 111.

[0037] In this embodiment, the top surface of the water storage tank 111 is provided with multiple second water collection holes 115. Rainwater can also enter the water storage tank 111 through the second water collection holes 115. In the event of a large water volume, excess rainwater can also be discharged through the first water collection hole 114 and the second water collection hole 115. Collecting and reusing rainwater can conserve and utilize natural resources, and also avoid roadbed quality problems caused by excessive water in the roadbed body 200.

[0038] In this embodiment, the water-using mechanism includes two sets of water-using components 120 symmetrically arranged on both sides of the water storage component 110. The water-using component 120 includes a temporary water storage tank 121, a hydroponic tank 122, and an elastic component 123.

[0039] In this embodiment, one end of the outlet pipe 112 is connected to and communicates with the water storage tank 111, and the other end extends towards the bottom of the roadbed 200. In this embodiment, the end of the outlet pipe 112 away from the water storage tank 111 is connected to and communicates with the temporary water storage tank 121, and the distance between the bottom of the temporary water storage tank 121 and the road surface is greater than the distance between the water storage tank 111 and the road surface. Rainwater in the water storage tank 111 can automatically flow into the temporary water storage tank 121.

[0040] In this embodiment, a temporary water storage tank 121 is disposed inside the roadbed body 200 and located below the shoulder of the roadbed body 200. The temporary water storage tank 121 has a recessed receiving groove 124 from top to bottom for accommodating the hydroponic trough 122. Specifically, the temporary water storage tank 121 extends along the length direction of the roadbed body 200, and its cross-section is U-shaped along the length direction perpendicular to the roadbed body 200. In this embodiment, the hydroponic trough 122 is disposed in the receiving groove 124, with the sidewall of the hydroponic trough 122 abutting against the sidewall of the receiving groove 124. The elastic component 123 has its two ends along the extension / contraction direction connected to the bottom wall of the hydroponic trough 122 and the bottom wall of the receiving groove 124, respectively. In this embodiment, the hydroponic trough 122 extends along the length direction of the roadbed body 200, and the elastic component 123 includes multiple springs spaced apart along the length direction of the roadbed body 200.

[0041] The sidewall of the receiving tank 124 has multiple first connecting ports 1241, and the sidewall of the hydroponic tank 122 has multiple second connecting ports 1221, with the second connecting ports 1221 located below the first connecting ports 1241. In this embodiment, the multiple first connecting ports 1241 located on the sidewall of the same receiving tank 124 are spaced apart along the length direction of the basic body 200, and the multiple second connecting ports 1221 located on the sidewall of the same hydroponic tank 122 are spaced apart along the length direction of the basic body 200. When the hydroponic tank 122 moves up and down relative to the temporary water storage tank 121, it can be connected or disconnected through the first connecting ports 1241 and the corresponding second connecting ports 1221.

[0042] A grid plate 125 for fixing plants is provided at the end of the hydroponic tank 122 away from the elastic component 123.

[0043] This embodiment also provides a construction method for roadbed structure 10, including: filling the roadbed body 200 to about half its length, leveling and compacting it, laying the above-mentioned water storage structure 100, and then continuing to fill the roadbed body 200 until the construction of the roadbed structure 10 is completed.

[0044] The roadbed structure 10 provided in this embodiment works as follows: When there is sufficient rainwater in the hydroponic trough 122, the weight of the hydroponic trough 122 and the elastic force of the spring reach equilibrium. The second connecting port 1221 is located above the first connecting port 1241, and the hydroponic trough 122 and the temporary water storage tank 121 are separated, so the water in the temporary water storage tank 121 will not enter the hydroponic trough 122. When the rainwater in the hydroponic trough 122 evaporates and decreases, the elastic force of the spring is greater than the weight of the hydroponic trough 122. At this time, the hydroponic trough 122 moves up until the first connecting port 1241 and the second connecting port 1221 begin to connect, and the water in the temporary water storage tank 121 begins to enter the hydroponic trough 122 until the weight of the hydroponic trough 122 and the elastic force of the spring reach equilibrium again, thereby enabling timely replenishment of the water in the hydroponic trough 122 to prevent the plants from withering.

[0045] In summary, the roadbed structure 10 and its construction method provided in this embodiment can form a road green belt to beautify the road environment, and at the same time, it can achieve water storage within the roadbed. When the water volume in the green belt decreases in hot weather, it can automatically and promptly replenish the water in the green belt without human intervention, preventing the plants in the green belt from withering due to lack of water, maintaining the ecological environment, and is economical and practical, with great value for promotion and application. The construction method is simple and easy to operate.

[0049] In this embodiment, a first connecting port 2241 is provided on the side wall of the receiving tank 224; a second connecting port (not shown) is provided on the side wall of the hydroponic tank (not shown). The first connecting port 2241 located on the side wall of the same receiving tank 224 extends along the length direction parallel to the road base body (not shown), and the second connecting port located on the side wall of the same hydroponic tank extends along the length direction parallel to the road base body.

[0050] Compared to Example 1, the structure of the first connecting port 2241 and the second connecting port provided in this example has the advantage of large water output.
