Description

Technical Field

[0001] The invention relates to the technical field of soil improvement, in particular to a fiber sponge meson soil improvement base material. Background Art

[0002] In modern urban construction, the original soil at construction sites is often unsuitable for plant growth due to its physical and chemical properties, and has problems such as poor soil structure, lack of nutrients, and low water retention capacity. This results in the need to transport and replace unsuitable soil before planting plants, which increases construction costs and time, and also causes certain pollution and pressure on the environment.

[0003] Traditional soil replacement methods usually involve a large amount of soil transportation and treatment, resulting in high economic costs and potential environmental risks. In addition, due to the large differences in soil properties in different regions, a simple one-size-fits-all soil replacement strategy cannot effectively meet the needs of plant growth, but may lead to unsatisfactory soil improvement effects, affecting subsequent ecological restoration and landscape effects.

[0004] Existing technologies for soil improvement mostly rely on the introduction of external soil materials, lack of full utilization and improvement of the original soil, and limit the efficient use of soil resources. Therefore, there is an urgent need for a new soil improvement method that can comprehensively consider local soil characteristics without relying on a large amount of external resources, and carry out scientific and effective improvement to meet the needs of plant growth and reduce the burden of construction on the environment.

[0005] For this purpose, we propose a fiber sponge meson soil improvement base material. Summary of the invention
