A rainwater purification tree box system

Abstract

The invention relates to the technical field of city afforestation tree boxes, and discloses a rainwater purification tree box. The rainwater purification tree box comprises a box body and a water inlet pipe; the box body comprises an outer wall, a cover plate and a base plate, wherein the cover plate and the base plate are connected with the outer wall; a water filtering layer and a soil layer are sequentially arranged in the box body from top to bottom; the water inlet pipe penetrates the outer wall of one side of the box body, the water filtering layer and the soil layer to extend out form the outer wall of the other side of the box body; a water leakage hole and a water inlet are formed in the water inlet pipe, the water leakage hole is formed in the water filtering later, the water inlet is formed in the soil layer, and the outer wall is a breathable seepage-proofing sand layer. By means of the rainwater purification tree box, rainwater in the rainwater purification tree box can be recycled after being filtered by the box body; and the rainwater purification tree box has the beneficial effects of being good in purification effect and saving energy; in addition, the outer wall is the breathable seepage-proofing sand layer, the breathable seepage-proofing performance is obvious, and trees better grow and develop.

Description

technical field [0001] The invention relates to the technical field of urban greening tree boxes, in particular to a rainwater purification tree box system, in particular to a rainwater purification tree box system which is beneficial to tree growth and can purify rainwater. Background technique [0002] Most of the existing tree boxes adopt concrete pouring or box structure, holes are opened on the curb, rainwater grates are installed, and then the reinforced concrete cover is covered. The material of concrete is airtight, and the stored rainwater will deteriorate, which seriously affects the quality of rainwater and is not conducive to tree growth and tree root respiration. Concrete materials consume a lot of rock or land resources, and the pouring, transportation and installation are inconvenient and expensive. [0003] The rainwater in the existing tree box will be directly drained through the rainwater outlet, and the rainwater resources cannot be recycled. With the i...

AI Technical Summary

Problems solved by technology

The material of concrete is airtight, and the stored rainwater will deteriorate, seriously affecting the quality of rainwater, which is not conducive to tree growth and tree root respiration

Concrete material consumes a lot of rock or land resources, and it is inconvenient to pour, transport and install, and the cost is high

[0003] The rainwater in the existing tree box will be directly drained through the rainwater outlet, and the rainwater resources cannot be recycled

With the intensification of urbanization, a large amount of rainwater runoff is directly discharged without treatment, which increases the burden on urban drainage facilities, especially the initial rainwater is mixed with a large amount of surface pollutants, which flows into the river, making the water quality of the river black and smelly
