Technical Field

[0001] This utility model relates to the field of municipal drainage technology, specifically a water collection and purification device for sunken green belts under municipal roads. Background Technology

[0002] Sunken green belts along municipal roads are a form of urban sunken green space. As an ecological urban rainwater utilization technology, urban sunken green spaces have been widely used in urban communities and squares, and have achieved good results in mitigating urban flooding and improving the urban ecological environment. Currently, sunken green belts are equipped with water collection devices at the bottom to collect water that seeps down from the green belt. The water seeps down and is filtered to some extent. However, the water collection devices at the bottom of the sunken green belts currently drain the water directly without reusing the collected water. In dry weather, the green belts still need to be watered by the municipal greening department.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a water collection and purification device for sunken green belts under municipal roads. Utility Model Content

The water-retaining and seepage-proof layer covers the water collection cover, which is located at the inner bottom of the sunken green belt cavity. Water channels are provided at the bottom of both the sunken green belt cavity and the bottom of the water collection cover. Water in the water collection cover is collected into the water collection trough through the two water channels. Warp and weft cotton strips are also provided within the sunken green belt cavity, and longitudinal cotton strips are connected to the warp and weft cotton strips. The longitudinal cotton strips pass through the water-retaining and seepage-proof layer, the water collection cover, and the water channels in sequence and enter the water collection trough.

[0006] Furthermore, the water collection and purification device also includes a longitudinal conduit, which passes through the water-retaining and seepage layer, the water collection cover, and the water passage trough in sequence before entering the water collection trough, with the longitudinal cotton strip located inside the longitudinal conduit.

[0007] Furthermore, a filter cloth is laid on the water-retaining and permeable layer.

[0008] Furthermore, the water-retaining and permeable layer is one of zeolite, diatomaceous earth, or ceramics.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] This utility model provides a technical solution: Please see Figure 1-3A water collection and purification device for sunken green belts along municipal roads is disclosed. The sunken green belt includes a cavity 1, which is typically filled from bottom to top with a gravel layer, a sand layer, and a planting soil layer. Green plants are planted on the planting soil layer. The water collection and purification device is located below the cavity 1 and includes a water collection trough 2. The device also includes a water-retaining and seepage-proof layer 3 and a water collection cover 5 located within the cavity 1. The water-retaining and seepage-proof layer 3 covers the water collection cover 5. Water channels 6 are provided at the bottom of the recessed green belt cavity 1, the bottom of the recessed green belt cavity 1, and the bottom of the water collection cover 5. Water in the water collection cover 5 is collected into the water collection trough 2 through the two water channels 6. Warp and weft cotton strips 9 are also provided in the recessed green belt cavity 1. The warp and weft cotton strips 9 are multiple cotton strips arranged in a warp and weft pattern. The warp and weft cotton strips 9 are located inside the planting soil layer. The warp and weft cotton strips 9 are connected to longitudinal cotton strips 8. The longitudinal cotton strips 8 pass through the water-retaining and seepage layer 3, the water collection cover 5, and the water channels 6 in sequence and enter the water collection trough 2.

[0015] The water-retaining and permeable layer 3 uses a metal filter frame, which can be filled with one of the following: zeolite, diatomaceous earth, or ceramic. The water-retaining and permeable layer 3 ensures that a certain amount of water is retained in the green belt, while more water flows directly into the water collection cover 5. In order to prevent sand and soil from seeping down, a filter cloth 4 is laid on the water-retaining and permeable layer 3. The filter cloth 4 filters sand and soil, and then flows from the water collection cover 5 into the water collection trough 2. The longitudinal cotton strips 8 and the warp and weft cotton strips 9 draw the water in the water collection trough 2 back into the planting soil layer.

[0016] In order to protect the longitudinal tampons 8, the water collection and purification device also includes a longitudinal conduit 7. The longitudinal conduit 7 is supported by a support rod located at the outlet of a water channel 6 below. The longitudinal conduit 7 passes through the water-retaining and seepage layer 3, the water collection cover 5, and the water channel 6 in sequence and enters the water collection channel 2. The longitudinal tampons 8 are located inside the longitudinal conduit 7.

[0017] Example 1 The water collection tank 2 is a sealed box. An overflow trough is provided on the upper side of the water collection tank 2. The overflow trough is connected to a drainage branch pipe 10. The other end of the drainage branch pipe 10 is connected to the municipal drainage pipe to introduce the water in the water collection tank 2 into the municipal drainage pipe. Since the overflow trough is located at a high position, it is necessary to ensure that the water storage capacity in the water collection tank 2 is large before it can be drained.

[0018] Example 2 The water collection trough 2 is a precast concrete drainage trough, that is, the water collection trough 2 is the main drainage. The water collection trough 2 adopts modular connection. The upper part of the interior of the precast concrete drainage trough is equipped with a water collection tank 12. The outside of the water collection tank 12 is supported and suspended by the support frame 13. The water collection tank 12 and the water collection cover 5 are interconnected by the water passage trough 6. Overflow ports are opened on both sides of the water collection tank 12. Water seeping down from the green belt first enters the water collection tank 12, and then flows into the water collection trough 2 through the overflow port on the water collection tank 12. Since the overflow port is located high, it is necessary to ensure that the water storage capacity in the water collection tank 12 is large before it can be drained.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
