[0002] In the practice of sponge city construction, setting up sponge facilities is an important means to improve urban drainage and flood prevention capabilities and promote the utilization of rainwater resources. However, in actual applications, it is often the case that rainwater on roads in sponge facilities is only discharged to sponge facilities through the water holes in the road curbs and grass-planted ditches. In particular, when the amount of rainwater exceeds the design capacity of the sponge facilities, the rainwater in the sponge facilities may accumulate rapidly. At this time, the rainwater can only be discharged to the rainwater pipe network through the overflow port in the sponge facilities. There is a situation where the overflow port has insufficient drainage capacity and the accumulated water on the road cannot be discharged in time, which may even cause safety problems such as waterlogging.
[0003] Therefore, how to improve the ability of sponge facilities to cope with extreme weather conditions while ensuring their normal operation has become an urgent problem to be solved in the current sponge engineering design and construction. Utility Model Content

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example 1
[0025] Figure 1 and Figure 2 The rainwater outlet structure shown in the figure is used for construction drainage and overflow of sponge facilities, which is applied during the construction of sponge facilities 5.
[0026] The invention comprises a rainwater inlet 1, which is arranged between a sponge facility 5 and a road curb 6, and a rainwater inlet cover plate 2 is arranged on the rainwater inlet 1.
[0027] The rainwater inlet cover plate 2 is divided into a solid section 21 and a grille section 22.
[0028] An overflow port 51 connected to the rainwater inlet 1 is provided on one side of the sponge facility 5 close to the rainwater inlet 1. A solid water receiving plate 4 extending obliquely upward into the rainwater inlet 1 is provided at the bottom of the overflow port 51. The solid water receiving plate 4 with a certain slope facilitates the collection of rainwater by the sponge facility 5.
[0029] The grille section 22 of the rainwater inlet cover plate 2 is located on a side close to the road curb 6 , and the solid water-bearing plate 4 is located below the solid section 21 of the rainwater inlet cover plate 2 .
[0030] like Figure 5 As shown, the gully cover plate 2 is arranged on the gully 1 through the gully well seat 3 fixed to the upper end of the gully 1, the bottom of the inner side of the gully well seat 3 is provided with a protrusion, and the bottom of the outer side of the gully cover plate 2 is provided with a groove that is plugged in and out with the protrusion of the gully well seat 3. The plug-in structure is adopted to facilitate the replacement of the placement of the gully cover plate 2 to match different applications.
[0031] A water hole 61 connecting the road 7 and the rainwater inlet cover plate 2 is provided on the upper surface of the road curb 6 close to the road 7 .
[0032] The rainwater inlet 1 is connected to the rainwater well through the rainwater inlet connecting pipe 11 .
[0033] The angle between the solid water bearing plate 4 and the horizontal plane is in the range of 5-15°.
[0034] During the construction of the sponge facility 5, if it rains, the road drainage needs to be discharged in time, so as not to affect the construction of the greening sponge facility 5. At this time, the rainwater inlet cover plate 2 is a movable structure, which is directly plugged into the rainwater inlet well seat 3. The grille section 22 of the rainwater inlet cover plate 2 is located on the side close to the road curb 6, and the solid water bearing plate 4 is located below the solid section 21 of the rainwater inlet cover plate 2, that is, the grille section 22 avoids the solid water bearing plate 4 below;
[0035] After passing through the water hole 61 , the road rainwater can be directly discharged downward into the rainwater outlet 1 through the grid section 22 of the rainwater outlet cover plate 2 , and then discharged into the rainwater well through the rainwater outlet connecting pipe 11 .
[0036] Example 2
[0037] It is basically the same as Example 1, except that: after the sponge facility 5 is put into use, Figure 3 and Figure 4 As shown, the grille section 22 of the rainwater inlet cover plate 2 is located on a side close to the sponge facility 5 , and the solid water-bearing plate 4 is located below the grille section 22 of the rainwater inlet cover plate 2 .
[0038] At this time, the rainwater inlet cover plate 2 is rotated 180 degrees on the basis of Example 1 and then plugged into the rainwater inlet well seat 3 and fixed. The road rainwater flows through the water hole 61 and then flows through the solid section 21 of the rainwater inlet cover plate 2, and then flows downward from the grille section 22 of the rainwater inlet cover plate 2 through the solid water receiving plate 4 and discharged from the overflow port 51 to the sponge facility 5, completing the process of collecting road rainwater to the sponge facility 5;
[0039] When the rainwater of the sponge facility 5 is stored to the designed elevation, the excess rainwater overflows into the rainwater inlet 1 through the overflow port 51 and then is discharged into the rainwater well through the rainwater inlet connecting pipe 11.
[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
