[0008] Furthermore, a filter screen is provided at the water inlet of the connecting pipe, and the filter screen is fixedly connected to the inner wall of the drainage ditch.

[0009] Furthermore, the water collection trough includes a groove, a connecting pipe is connected to the groove, a groove cover is arranged on the groove, a geotextile is laid on the groove cover, and the upper end of the capillary water column passes through the groove cover and the geotextile in turn and extends to the soil above the water collection trough.

[0010] Furthermore, the connection between the capillary water delivery column and the geotextile is sealed.

[0011] Furthermore, one end of the water collection tank is connected to a water inlet pipe, on which a water inlet valve is installed, and the other end of the water collection tank is connected to a drain pipe, on which a drain valve is installed, the water inlet pipe is connected to a municipal water supply pipeline, and the drain pipe is connected to a drainage ditch.

[0012] Furthermore, the water inlet valve and the water discharge valve are both arranged and installed in the manhole.

[0013] Beneficial effects of the utility model:

[0014] 1. It can collect rainwater and use it to supply water to vegetation in green belts, which helps save water resources and reduce the intensity of manual irrigation, making it more convenient to use;

[0015] 2. By combining natural rainwater collection with municipal water supply, on the one hand, it can ensure the normal irrigation of the green belt when there is no rain, and on the other hand, it can also realize the flushing of the collection tank and achieve long-term and stable use.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0022] Embodiments of the present utility model:

[0023] like Figure 1-3As shown, in this embodiment, the drainage ditch 2 next to the road 1 is connected to the water collecting tank 4 through a connecting pipe 5, and a filter screen 51 is arranged at the front end of the connecting pipe 5. The filter screen 51 is fixed on the inner wall of the drainage ditch 2 (screws, etc.), and the water collecting tank 4 is arranged below the green belt 3.

[0024] The water collecting trough 4 includes a groove 41, a groove cover 42 is arranged on the groove 41, and a geotextile 43 is covered on the groove cover 42. A capillary water column 44 (porous building material, such as foam concrete, porous bricks, etc.) is arranged in the groove. The capillary water column 44 passes through the groove cover 42 and the geotextile 43 and extends to the loam (loose soil) above the water collecting trough 4. The connection between the capillary water column 44 and the geotextile 43 is adhesively sealed.

[0025] One end of the water collection tank 4 is connected to the municipal water inlet pipe 45, and an inlet valve 451 is installed on the inlet pipe 45. The other end of the water collection tank 4 is connected to the drain pipe 46, and the drain pipe 46 is connected to the drainage ditch 2, and a drain valve 461 is installed on the drain pipe 46, wherein the inlet valve 451 and the drain valve 461 are both arranged in the manhole 6.

[0026] The principle of this utility model is:

[0027] The utility model can collect rainwater when in use. When it rains during use, on the one hand, a certain amount of water will accumulate in the drainage ditch 2, and this part of water can overflow into the water collection tank 4 through the connecting pipe 5. On the other hand, rainwater can also be collected in the water collection tank 4 by infiltrating through the geotextile 43 from the soil in the green belt 3, thus realizing the collection of rainwater.

[0028] The rainwater collected in the trough 4 can be transferred to the soil above the trough 4 through the water conveying effect of the capillary water column 44 on sunny days, thereby replenishing the water for the plants in the green belt 3, effectively avoiding the need for manual watering, saving manpower and being more convenient. It should be noted that the soil in the municipal green belt 3 is generally loam, that is, loose soil, and will not become compacted. Therefore, the blockage of the capillary water column 44 can be effectively avoided, thereby ensuring stability during long-term use.

[0029] During use, due to the entry of muddy water in the drainage ditch 2, mud and dirt will appear in the water collection tank 4 after long-term use. At this time, the water inlet pipe 45 can be opened for flushing. At the same time, in the hot summer, when there is no water stored in the water collection tank 4, municipal water supply can also be carried out through the water inlet pipe 45, thereby effectively reducing the burden of operations and making it more convenient to use.
