Description

A self-irrigating ecological tree pond

technical field

The utility model relates to a tree pond, in particular to a self-irrigation ecological tree pond, which belongs to the field of garden greening.

Background technique

In recent years, many cities in my country have experienced frequent rainstorms and waterlogging. By introducing ecological tree ponds into cities, multiple benefits such as waterlogging prevention, water resource utilization, and landscaping can be achieved to a certain extent. As a small bioretention facility, the ecological tree pond is generally composed of planting soil layer, sand filter layer, drainage system and trees and shrubs. The ecological tree pond has become a low-impact development facility widely used in foreign streets due to its advantages of small footprint and flexible application. After collecting surface runoff, it is discharged into municipal pipelines by soil infiltration. It is a new type of road ecological rainwater outlet.

The existing ecological tree ponds usually purify the rainwater and then discharge it into the municipal pipeline, that is, use the sand and gravel filter layer to filter the rainwater layer by layer. The Chinese utility model patent with the announcement number CN207905070U discloses "a tree pond based on the concept of sponge city", which is stored in the plain soil layer by allowing the rainwater to penetrate through the planting soil layer, the sand filter layer and the plain soil layer in sequence. In the water storage tank, water can be stored in rainy days; at the same time, when the water is dry, the rainwater is pumped out of the water storage tank by the pump, and then drip irrigation is carried out on the planting soil layer through the drip irrigation pipe, so that the roots of the trees can absorb water. This kind of ecological tree pond that is self-irrigated by the water storage tank has defects. Because the amount of rainwater cannot be determined during urban rainstorms, it is easy to exceed the capacity of the water storage tank, and the supply and distribution of water resources cannot be effectively carried out.

In addition, the self-watering ecological tree pond used in the sponge city uses the combination of the outer water collecting tank and the inner planting box with wooden seats to collect rainwater and slowly self-watering, but the rainwater delivery system is too complicated and cannot be effective. Issues concerning the supply and distribution of water resources.

Utility model content

The purpose of the utility model is to provide a self-irrigation ecological tree pond, which can solve the technical problem that the amount of rainwater cannot be determined during the urban rainstorm, the internal capacity of the water storage tank is easily exceeded, and the supply and distribution of water resources cannot be effectively performed.

The purpose of the present utility model can be achieved through the following technical solutions:

Beneficial effect: after the rainwater is purified by the filter tank body, it can enter the interior of the water storage tank through the conveying system. The water in the water storage tank can not only be drip-irrigated through the drip irrigation pipe, but also the rainwater can be discharged to the municipal rainwater pipeline for diversion when the rainwater stored in the water storage tank is excessive, so as to ensure the timely discharge of rainwater, and the upper part of the filter tank body is not easy to accumulate rainwater.

As a technical optimization scheme of the present invention, the conveying system includes a seepage pipe and a drain pipe, the water storage tank is connected to the drip irrigation pipe through the drain pipe, a pump is installed between the drain pipe and the drip irrigation pipe, and the filter tank body is connected through the seepage pipe. In the water storage tank, the rainwater enters the interior of the water storage tank from the seepage pipe after being filtered by the filter tank body. When the plant needs drip irrigation, the water pump will pump the water inside the water storage tank into the drip irrigation pipe through the drain pipe for drip irrigation.

As a technical optimization scheme of the present invention, a pressure switch water outlet is installed at the connection between the water storage tank and the municipal rainwater pipeline, and the water outlet of the pressure switch is an air pump pressure switch. When the pressure of the water inside the water storage tank is greater than the set full When the water pressure is on, the air pump pressure switch is automatically turned on, so that the excess rainwater enters the interior of the municipal rainwater pipeline to ensure that the rainwater can be discharged in time, and the upper part of the filter tank body will not accumulate water. When the pressure of the internal water is lower than the set pressure, the air pump pressure switch will automatically close. Using the air pump pressure switch to control the opening or closing of the water outlet is the use of the prior art.

As a technical optimization scheme of the present invention, the two ends of the water storage tank are respectively connected to the water seepage pipe and the drain pipe through the water inlet and the drain port, and the water storage tank is composed of four groups of interconnected water storage tank bodies. The inner wall of the water storage tank is covered with a waterproof film, and the water storage tank body can increase the water storage capacity of the water storage tank, and the mutual penetration ensures the common water storage inside.

As a technical optimization scheme of the present invention, the interior of the filter tank body is sequentially provided with a ground cover layer, a planting soil layer, a sandstone layer and a gravel cushion layer from top to bottom, and the seepage pipe is arranged on the gravel cushion layer. At the bottom of the water tank, when the rainwater penetrates, it goes through the ground cover, planting soil, sand and gravel layers in order to purify.

The beneficial effects of the present utility model:

A self-irrigation ecological tree pond is adopted, so that the rainwater is stored in the water storage tank after physical filtration for many times, which is cleaner and less likely to block the pipeline. The water pump can transport the rainwater in the water storage tank to the drip irrigation pipe through the water outlet, so that the water can reach the planting soil layer, and the rainwater can be used to save water resources. When the rainwater inside the storage tank is excessive, the pressure switch can be automatically opened, so that the excess rainwater enters the municipal drainage pipeline. When it rains, water storage is realized, and when the rainwater penetrates, it is stored in the water storage tank after being physically filtered for many times. for the roots of trees to absorb water. At the same time, in the event of heavy rain, the excess rainwater is effectively discharged into the municipal rainwater pipeline, which can ensure the timely discharge of rainwater without the phenomenon of water accumulation, making the distribution of rainwater reasonable.
