Description

A buried anti-clogging tree root irrigation device

Technical Field

The utility model relates to the technical field of tree irrigation, in particular to an underground anti-clogging tree root irrigation device.

Background Art

In cities where the ecological environment is highly affected by human activities, trees can be regarded as natural regulators of urban ecosystems. The tangled root system of trees can make urban soil become like a natural sponge, absorbing rainwater, and then transporting it to the leaves through transpiration through the trunk, and releasing it back into the atmosphere through dense pores, thereby regulating air humidity; the mesh structure of tree roots can also prevent soil erosion, keep the soil hydrated, help prevent natural disasters such as floods and mudslides, and reduce the pressure on stormwater channels and urban water treatment systems; in addition, leaves can capture carbon and other pollutants in the air, playing a vital role in responding to climate change and preventing and controlling urban air pollution.

With the booming development of the gardening and greening industry, the green coverage rate of urban built-up areas has increased year by year. In order to protect the green area of urban built-up areas, the maintenance and irrigation of trees have become important issues. At present, tree irrigation mainly uses aerial sprinkler irrigation and underground drip irrigation technology. Sprinkler irrigation is an irrigation method that uses professional equipment to spray pressurized water into the air and evenly sprinkle it on the soil surface for plants to absorb. Aerial sprinkler irrigation is suitable for low plants such as shrubs, lawns, and flowers, and the spraying is dense and uniform. However, the uniformity of its irrigation is greatly affected by wind. Excessive wind will increase water loss and waste water resources; at the same time, the equipment price and management and maintenance costs of sprinkler irrigation are high. Underground drip irrigation uses pressure pipes to transport water to the sprinkler, and the sprinkler injects irrigation water into the soil under a certain working pressure. After the water drips or seeps out at a constant low flow rate through the sprinkler, it diffuses around in the soil under the dripper in the form of unsaturated flow. The water flow rate of the dripper is very small, and the irrigation time is long. Drip irrigation pipes are generally buried in the soil. Long-term water supply to the soil will affect the normal breathing of the roots of trees. In addition, underground drip irrigation technology has high requirements on water quality, the drip outlets are easily clogged, and the maintenance cost is high.

In this embodiment, the underground anti-clogging tree root irrigation device is used in a shallow root shrub forest in a sandy environment. Since the root depth of the shallow root shrub is relatively shallow, the diversion pipe 100 is cut to 45 cm to reduce the use of plastic pipes and protect the environment. The underground anti-clogging tree root irrigation device is buried in the soil at the middle position between the trunk and the edge of the crown, and the rain collection surface 400 is set at the same level as the ground. When it rains, rainwater is collected by the rain collecting surface 400, and the rainwater is directed into the soil around the roots of trees by the diversion pipe 100. The protective sleeve 800 is wrapped around the outside of the diversion pipe 100 to prevent sandy soil and tree roots from invading and growing into the underground anti-clogging tree root irrigation device through the gaps in the diversion pipe 100. When it rains less, tap water is introduced from the water supply branch pipe of the irrigation system into the water inlet pipe 500, and the tap water is sprayed on the diversion pipe 100 in an umbrella shape by the pressure compensation fountain nozzle 600.
