Drainage planting hole structure with purifying and recycling functions

Abstract

The invention relates a drainage planting hole structure with purifying and recycling functions. The drainage planting hole structure consists of three parts, namely a planting mechanism, a flow guiding mechanism and a collecting and purifying mechanism, can promptly drain residual water in planting holes of clay soil to prevent transplanting soil balls from being soaked and to reduce the survival rate of nursery stocks, and also can purify and recycle residual water in tree holes. With respect to the characteristics that clay soil is poor in water and air permeability, the arc-shaped lug boss planting hole structure is adopted, and a cobblestone layer, a rubble layer, a zeolite layer and a coal ash layer are sequentially arranged in a purification bath from bottom to top, so that water is preliminarily purified through an ecological filtering layer from bottom to top by virtue of the water pressure action, residual water is purified and recycled on the basis of promptly discharging water accumulated in and around the planting holes, and accordingly, the survival rate of the nursery stocks and recycling of water resources are improved to the utmost extent. The drainage planting hole structure is suitable for transplanting large nursery stocks, such as street trees of cities in clay soil regions.

Description

technical field [0001] The invention relates to the field of ecological environment, in particular to a drainage planting hole structure for purification and reuse, which is especially suitable for planting street trees in sticky soil with poor drainage. Background technique [0002] In urban landscaping, arbor shows its unique charm. It is not only the basic skeleton of urban landscaping, but also exerts its landscape effect in the shortest time. It is also very important in improving the urban ecological environment and has certain ecological benefits. and social benefits. However, when transplanting arbors in landscaping, some problems such as high requirements for transplanting techniques, high transplanting costs, low survival rate, and easy waste of resources have been exposed. Since the survival rate of seedlings is closely related to the water permeability and air permeability around the soil ball of the seedlings, especially the poor water permeability and air perm...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of sticky soil with poor water permeability and air permeability, easy to cause water accumulation in tree holes after transplanting arbors, soak the roots of seedlings, reduce the survival rate of seedlings and cause waste of water resources, and propose a drainage planting method for purification and reuse. Hole structure, on the basis of timely removing the accumulated water in and around the planting hole, purify and reuse the excess water, so as to avoid the tree root system from being soaked in water, which is conducive to the growth of new roots and improves the survival rate of tree transplantation
