[0029] [First embodiment]

[0030] like Figure 1-5 The figure shows an assembled grass-planting ditch provided by the first embodiment of the utility model. Figure 1 As shown, the groove space is filled with a filler layer 4, and the top of the filler layer 4 is filled with a planting soil layer 2. The rainwater passing through the planting soil layer and the filler layer can be effectively slowed down, dissipated, accumulated and purified, and finally enters the infiltration and storage module for storage, thereby reducing the possibility of soil erosion and garbage deposition.

[0031] The top of the planting soil layer 2 is planted with green plants through the planting module 1, such as Figure 3-4As shown, the planting module 1 in this embodiment includes a planting body 11, and a plurality of planting holes 12 are evenly opened inside the planting body 11. Green plants can pass through the planting holes 12 and extend into the planting soil layer 2, thereby further improving the ability to decelerate, dissipate energy, accumulate and purify rainwater. Preferably, the planting module 1 is spliced ​​into a concave shape at the top of the planting soil layer 2, thereby further improving the collection and convergence of rainwater.

[0032] like Figure 1 As shown, in this embodiment, a separation layer 3 is provided between the ends of the planting soil layer 2 and the filling layer 4 and the inner wall of the groove space, and the separation layer 3 is made of a permeable geotextile to facilitate water permeation while reducing the outflow of impurities and soil.

[0033] like Figure 1 and Figure 5 As shown, a plurality of infiltration and storage modules 5 are installed at the bottom of the packing layer 4. The water outlets of the infiltration and storage modules 5 are connected to the rainwater well 7 via the drainage pipe 6. After passing through the infiltration and storage modules, the rainwater is discharged into the rainwater network through the drainage pipe, thereby improving the water storage capacity and further purifying the water quality.

[0034] like Figure 5 As shown, the infiltration and storage module 5 in this embodiment includes an infiltration and storage body 51, a water inlet 52 is opened on the top of the infiltration and storage body 51, and a water outlet (not shown) is also arranged on one side of the infiltration and storage body 51. Adjacent infiltration and storage bodies 51 are connected through the water outlets, and the water outlet of the outermost infiltration and storage body 51 is connected to the drain pipe 6. Rainwater enters the infiltration and storage body 51 through the water inlet 52 and is discharged through the drain pipe 6, thereby realizing the flow of rainwater between adjacent infiltration and storage modules 5 and the flow from the infiltration and storage module 5 to the drain pipe 6. Preferably, a filter medium can be installed at the position of the water inlet 52 to further filter and purify the rainwater entering the infiltration and storage module 5.

[0035] Preferably, in this embodiment, a connection portion 53 is provided on the outer edge of the seepage storage module 5, and the fixed connection between adjacent seepage storage modules 5 and between the seepage storage module 5 and the drain pipe 6 can be achieved by the cooperation of an external fixing member (such as a bolt, a screw, etc.) and the connection portion 53. At the same time, mutually cooperating positioning portions 54 are respectively provided on the top and bottom of the seepage storage module 5, such as Figure 5 As shown, the positioning portion 54 can be set to a shape structure that is convex at the top and concave at the bottom (not shown) and can be matched to facilitate positioning and installation, so as to meet the requirements of stacking the seepage storage module 5 in multiple layers, and positioning and installing the seepage storage module 5 at the bottom of the packing layer 4. Through the setting of the connecting portion 53 and the positioning portion 54, the seepage storage module 5 can be provided with one or more according to the seepage storage requirements, and when multiple seepage storage modules 5 are selected and installed, they can be arranged in a single layer or in multiple layers.

[0036] As a further preference, the seepage storage module 5 in this embodiment can also directly select a storage module for a prefabricated biological retention facility disclosed in the patent application with application number 202322927354.8.

[0037] As a further preference, the drain pipe 6 in this embodiment is configured as a one-way drain pipe (for example, by adding a one-way valve inside) to prevent rainwater in the rainwater well 7 from flowing back into the infiltration storage module 5 during rainfall drainage.

[0038] In addition, if Figure 1 As shown, the rainwater well 7 includes a top overflow chamber 71 and a bottom water storage chamber 72. The overflow chamber 71 is provided with an overflow port to facilitate the direct overflow and discharge of a large amount of rainwater during rainfall. The water storage chamber 72 is connected to the drain pipe 6 for temporarily storing rainwater purified and stored by the infiltration and storage module 5.

[0039] During the specific operation of this embodiment, after rainfall, rainwater flows into the grass-planted ditch. The rainwater passing through the planting soil layer and the filler layer can be effectively slowed down, dissipated, accumulated and purified, and finally enters the infiltration and storage module for storage, thereby reducing the possibility of soil erosion and garbage deposition. At the same time, a number of infiltration and storage modules are installed at the bottom of the filler layer. After passing through the infiltration and storage modules, the rainwater is discharged into the rainwater well through the drainage pipe and finally enters the rainwater pipe network, thereby improving the water storage capacity and further purifying the water quality.

[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
