Description

Road Rainwater Harvesting System

technical field

The utility model relates to the field of road rainwater collection, in particular to a road rainwater collection system.

Background technique

At present, the water permeability of the road surface in modern residential quarters is relatively low. When the environment is relatively harsh, a large amount of rainwater can only be discharged into the river through the drainage facilities, which greatly increases the burden on the drainage facilities, so a large amount of water will form on the road. , which adversely affects the comfort and safety of pedestrians. On the other hand, the amount of water infiltrated into the ground by roads with poor water permeability will gradually decrease, resulting in a decrease in the groundwater level. Industrial production and modern life have doubled the amount of groundwater extraction, causing insufficient water in the soil, Problems such as lack of oxygen and rising ground temperature directly affect the health of urban vegetation and further aggravate urban drought and water shortage.

detailed description

The specific embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the utility model, and are not intended to limit the utility model.

As shown in FIG. 1 , the utility model provides a road rainwater collection system, which includes a road surface 1 , a curb 4 is arranged on the edge of the road surface 1 , and a drainage hole 5 is opened on the side wall of the curb 4 . Optionally, as shown in Figure 2, in order to improve the drainage efficiency of the curb 4, the drainage holes 5 run through both sides of the curb 4, so when there is water accumulation on the road surface 1, the water will flow through the curb 4. Drainage hole 5, wherein, filter screen can also be set in the drainage hole 5, to block impurities etc. In other embodiments, the drainage hole 5 and the curbstone 4 can be in any shape, which is not limited by the present invention.

Simultaneously this system also comprises green belt 2, and this green belt 2 comprises crushed stone layer 21 and the planting soil layer 22 that is laid on this crushed stone layer 21, and crushed stone layer 21 can store moisture, and the vegetation of planting soil layer 22 can Moisture is absorbed from within the gravel layer 21 .

In addition, between the road surface 1 and the green belt 2, there is also a filter ditch 3, which includes a bottom wall 31 with an anti-seepage structure and two side walls 32, and one of the side walls 32 is provided with a drainage channel. The hole 5 communicates with the water inlet 6 , and the other side wall 32 is provided with a first water outlet 7 communicating with the gravel layer 21 , and the position of the water inlet 6 is higher than that of the first water outlet 7 . That is, the rainwater circulated by the drain hole 5 of the curb 4 will flow into the drain ditch 3 through the water inlet 6, and when the water storage capacity of the drain ditch 3 reaches the position of the first water outlet 7, the rainwater can flow into the grate. In the stone layer 21, the water stored by the gravel layer 21 will be absorbed and utilized by the vegetation in the planting soil layer 22, and assist the growth of plants such as flowers and trees.

Wherein, the cross section of the drain ditch 3 can be U-shaped, so that when rainwater enters the inside of the drain ditch 3, impurities such as sediment can be deposited to the bottom of the U-shaped groove, which is beneficial to the filtration of rainwater.

In this embodiment, as shown in FIG. 1 , the height of the lower edge of the drainage hole 5 above the road surface 1 is 2cm-3cm. That is, when the road surface water reaches or exceeds the range of 2cm-3cm, rainwater will enter in the drain hole 5, so that it can be guaranteed that the road surface water will not exceed 2cm-3cm, preventing a large amount of water accumulation on the road surface, which is not convenient for pedestrians to walk .

As shown in Figure 1, a permeation pipe 8 is arranged in the gravel layer 21, and one end of the permeation pipe 8 communicates with the first water outlet 7. The rainwater in the permeation pipe 8 can permeate into the gravel layer 21, so that the vegetation in the planting soil layer 22 absorbs moisture. In addition, in the embodiment of the present utility model, there can be two permeation pipes 8, which are respectively located on the upper and lower edges of the gravel layer 21. When it is in the dry season, the rainwater storage capacity in the filter ditch 3 Smaller, rainwater can flow into the permeation pipe 8 along the lower edge, so as to be used for the absorption of vegetation.

In this embodiment, a plurality of permeable holes are formed on the outer surface of the permeable pipe 8, so that the rainwater in the permeable pipe 8 can flow into the gravel layer 21 through the permeable holes for storage and utilization.

Returning to Fig. 1, in order to keep the liquid level of the filter ditch 3 from exceeding the preset position, an overflow pipe 9 communicating with the municipal pipe network is arranged in the filter ditch 3, and the position of the overflow pipe 9 is higher than that of the first outlet. The position of nozzle 7. Wherein, the cross-section of the mouth of the overflow pipe 9 needs to be large enough so that when the liquid level exceeds, the excess liquid can quickly overflow and be discharged into the municipal pipe network, and the position of the overflow pipe 9 should be higher than the first water outlet 7, so that when the water storage in the filter ditch 3 exceeds the first water outlet 7 and reaches the height of the overflow pipe 9, excess rainwater can be discharged to the municipal pipe network to ensure that the liquid in the filter ditch 3 Maintain a certain fluid level.

As shown in FIG. 1 , in this embodiment, the drain ditch 3 is covered with a drain cover 10 . Wherein, the water filter cover plate 10 is a water permeable structure formed by bonding granular aggregates through a water permeable adhesive. Its water-permeable aperture is much smaller than the particles in the water, not only can prevent large and small solid matter from entering the gutter 3, but can also preliminarily filter the sewage discharged into the gutter 3, thereby avoiding blockage of the ditch.

Further, as shown in FIG. 1 , arc-shaped grooves 11 are formed on the surface of the filter cover 10 , so that the impurities blocked on the outer surface of the filter cover 10 will deposit and accumulate in the low-lying arc-shaped grooves 11 In addition, on the one hand, the arc-shaped groove 11 can increase the seepage area, and on the other hand, it can also be used as an open ditch to collect and discharge road water when the rainfall is large.

Specifically, as shown in FIG. 1 , the side of the water filtering cover plate 10 in contact with the curb 4 is higher than the side away from the curb 4 . That is, there is a height difference on both sides of the arc-shaped groove 11. In the utility model, the water filter cover 10 connected with the curb 4 is flush with the road surface 1, and the side connected with the curb 4 is higher than the side far away from the curb 4. One side of curb stone 4, when avoiding excessive rainfall, the accumulated water in arc-shaped groove 11 the inside flows back to road surface 1.

As shown in FIG. 1 , the bottom wall 31 of the gutter 3 is lower than the bottom surface of the gravel layer 21 in order to facilitate mud collection and prevent sediment from entering the permeation pipe 8 of the gravel layer 21 . In this way, impurities such as silt are deposited on the bottom surface of the filter ditch 3, and the rainwater will not enter the permeation pipe 8 arranged in the crushed stone layer 21 to block the permeation pipe 8.

The optional implementation of the utility model has been described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the specific details of the above-mentioned implementation, within the scope of the technical concept of the utility model, the technical solution of the utility model can be carried out Various simple modifications, all of which belong to the protection scope of the present utility model.

In addition, it should be noted that the specific technical features described in the above specific embodiments can be combined in any suitable way if there is no contradiction. The combination method will not be explained separately.

In addition, any combination of various implementations of the present invention can also be made, as long as they do not violate the idea of the present invention, they should also be regarded as the disclosed content of the present invention.
