Problems solved by technology

At the same time, the green planting of most outdoor sites must rely on the soil, and the soil resources are becoming more and more scarce. The two have formed an irreconcilable contradictory situation. Therefore, it is urgent to reuse the existing waste resources and develop a garden planting method. soil, reducing the need for natural soil

Embodiment 1

[0038] A garden planting soil prepared from construction waste, comprising the following components in volume percentage: 40% of a mixture separated from construction waste, 50% of clay, and 10% of humus soil.

[0039] The selected construction waste needs to be piled up in the open air for a certain period of time, and has been washed by rainwater or soaked in water for many times.

[0040] The fineness of the mixture of construction waste separation is ≤2mm. Before separation and sieving, it is necessary to sort different materials according to the environmental protection department, and control the aperture of the final sieve to 2mm, and the mesh number of the sieve to be 10 mesh.

[0041] The pH value of the mixture after construction waste separation is controlled within the range of 7.5-8.0, if it exceeds the range, it can be soaked with water.

[0042] The core soil of the Quaternary red soil is selected as the clay soil, and the pH value of the humus soil needs to be ...

Abstract

The invention discloses garden planting soil prepared from construction waste. The garden planting soil comprises, by volume, 40 to 60% of a mixture obtained after separation of construction waste, 30to 50% of clay and 10% of humus soil. According to the invention, the garden planting soil is prepared from the mixture obtained after separation of construction waste, clay and humus soil; the prepared garden planting soil has a good physical structure; the humus soil is rich in elements needed by the growth of plants, and addition of construction waste improves the penetrability and permeability of the soil; and the prepared garden planting soil has stable and long-lasting soil properties and can provide a good soil growth environment for the growth and development of plants and promote plant growth. According to the invention, the mixture obtained after separation of construction waste is used as a main component of the garden planting soil, so an effective approach is provided for effective utilization of construction waste and on-site treatment of construction waste, garden planting soil is saved, and sustainable development of resources is realized. The invention also disclosesapplication of the garden planting soil.

Description

technical field [0001] The invention relates to the technical field of garden planting soil, in particular to a garden planting soil prepared from construction waste and its application. Background technique [0002] With the continuous development of urban construction, the amount of construction waste generated continues to increase. According to statistics, the total amount of construction waste in my country has accounted for 30% to 40% of the total amount of urban waste. Construction waste is mainly composed of muck, crushed stones, broken bricks, waste mortar blocks, waste concrete blocks, waste glass, waste ceramics, waste asphalt blocks, waste plastics, waste metal materials, waste bamboo and wood, etc. Most of the construction waste is stacked in the open air or landfilled without any treatment, and it needs to be cleaned up and consumes a lot of land. The problems of dust, dust and sand flying in the process of cleaning up and stacking will undoubtedly make the ci...
