Description

A water-saving green belt structure

technical field

The utility model relates to the technical field of environmental protection, in particular to a water-saving green belt structure.

Background technique

Green belts mostly refer to the strips for greening within the scope of road land. Green belts have the functions of beautifying the city, eliminating drivers' visual fatigue, purifying the environment, and reducing traffic accidents, and occupy an irreplaceable important position in urban planning.

The green plants in the green belt often need watering, especially in arid and semi-arid areas, the amount of watering is more. Existing irrigation methods are generally performed by sprinkler irrigation or professional irrigation equipment, and the amount of irrigation water is huge, which aggravates the water burden of cities in some arid regions, and the above-mentioned irrigation methods have high operating costs.

Utility model content

Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide a water-saving green belt structure, which can reduce the urban water burden by collecting rainwater and using it as irrigation water, and the water-saving green belt structure is simpler, Lower operating costs.

In order to achieve the above purpose, the utility model provides the following technical solutions: a water-saving green belt structure, including a number of green boxes for installation on both sides of the road and arranged in sequence, the green box is equipped with a support plate , and the support plate divides the green box into a planting area and a water-saving area arranged up and down; a partition plate is fixed at the bottom of the water-saving area and the partition plate divides the water-saving area into a buffer section and a water storage section in the horizontal direction, The surrounding wall of the buffer part is provided with a water inlet for guiding the runoff of the road surface into the buffer part, the bottom of the buffer part is connected with a drain pipe, and the partition plate is provided with a water storage for introducing part of the water in the buffer part into the water storage part. mouth; the water storage part is provided with a water-absorbing belt, one end of the water-absorbing belt is connected to the bottom of the water storage part and the other end penetrates into the planting area.

By adopting the above technical scheme, the runoff of the road surface can enter the buffer part through the water inlet, part of the water will enter the water storage part through the water storage port and be stored, and the other part of the excess rainwater will be directly discharged into the municipal pipe network through the drainage pipe . The water stored in the water storage part can be diverted to the soil in the planting area through the water absorption belt, so as to meet the needs of plant production. That is, by collecting rainwater and using it as irrigation water to reduce the city's water burden, and the water-saving green belt has a simpler structure and lower operating costs.

The further setting of the utility model is: there are several water leakage holes on the support plate.

By adopting the above technical solution, since part of the rainwater will fall into the planting area and infiltrate into the soil, if there is no water leakage hole, this part of the water will accumulate in the soil, which may cause root rot of plants and affect plant growth. The water leakage hole can drain this part of water in time, reducing the probability of plant root rot.

The utility model is further provided as follows: the upper side of the support plate is laid with a functional layer for blocking the soil on the upper side of the support plate and having a water-permeable function.

By adopting the above technical scheme, due to the setting of the water leakage hole, a part of the water may bring the soil under the water leakage hole during the process of leakage, resulting in soil loss in the planting area. The functional layer can reduce soil loss without affecting water seepage.

The utility model is further configured as follows: a collection box is installed on the underside of the support plate, and the end of the water-absorbing belt away from the bottom of the water storage part passes through the box wall of the collection box, the support plate, and the functional layer in turn and penetrates into the planting area; The bottom of the box is equipped with guides for guiding the suction belt.

By adopting the above-mentioned technical scheme, the collection box can collect the water leaked from the leakage hole, and in the later stage, the water-absorbing belt can reuse this part of the water back into the soil, so as to improve the utilization rate of rainwater. In order to allow the runoff on the road surface to flow into the water storage part, the height of the water storage port is lower than the height of the water inlet and lower than the height of the support plate, and the liquid level in the water storage part is naturally lower than the height of the water storage port, which eventually leads to Waste of vertical space between the reservoir and the reservoir. The setting of the collection box can properly utilize this part of the space and improve the space utilization rate, that is, increase the water storage capacity in a limited space.

The utility model is further set as: an overflow hole is opened on the box wall of the collection box.

By adopting the above technical scheme, when the water in the collection box accumulates to a certain height, it can overflow out of the collection box through the overflow hole, thereby releasing the pressure of the collection box.

A further setting of the present utility model is that: the overflow hole is located above the water storage part.

By adopting the above technical proposal, the water discharged from the overflow hole can fall into the water storage part and be collected by the water storage part for later reuse.

The utility model is further configured as follows: the bottom of the water storage part is lower than the bottom of the buffer part, and the water storage port is opened at the lowermost position of the partition plate.

By adopting the above technical scheme, when the runoff of the road surface is not very large, since the water storage port is set at the lowest position of the partition plate, the water storage part can still collect part of the water, that is, the above arrangement can improve the water storage part. Water storage capacity, thereby reducing the city's water burden.

The utility model is further set as: a filter screen is installed on the water storage port.

By adopting the above technical solution, the entry of impurities such as sediment into the water storage part is reduced, thereby reducing the probability of the water storage capacity of the water storage part being reduced due to sediment accumulation.

The further setting of the utility model is: a grid plate is installed at the water inlet.

By adopting the above technical solution, the grid plate is used to prevent large-sized debris such as leaves from entering into the buffer portion, thereby reducing the probability of blockage of drain pipes and water storage ports.

The utility model has the following advantages:

1. Collect rainwater and use it as irrigation water through the water storage department and collection box to reduce the city's water burden;

2. The structure of the water-saving green belt is simpler and the operating cost is lower;

3. When the water in the collection box accumulates to a certain height, it can overflow into the water storage part through the overflow hole for storage. On the one hand, it can relieve the pressure of the collection box; The discharged water is collected for later use.
