Ecological recovery method with combination application of planting ecological concrete and high-molecular aggregates

Abstract

The invention provides an ecological recovery method with combination application of planting ecological concrete and high-molecular aggregates. The ecological recovery method comprises the following steps: first, planting ecological concrete is prepared; second, high-molecular aggregates are prepared; third, a riverway or a slope is cleaned to meet construction requirements, fourth, after concrete curing is carried out for 28 days, the high-molecular aggregates are subjected to spray seeding on cured ecological concrete through a high-molecular aggregate spray seed machine. Because planting ecological concrete self has a lot of continuous pores, the high-molecular aggregates in a flow state flow through ecological concrete pores rapidly, finally all the concrete pores are filled with the high-molecular aggregates and the high-molecular aggregates are sprayed continuously, and the high-molecular aggregates can attach to pores and surfaces of the ecological concrete. Through implementation of the above method, the technology problem of low final greening rate due to that a large amount of surface layer covering soil is taken away because of rain wash is solved.

Description

technical field [0001] It is used in the fields of river slope protection engineering and ecological restoration engineering. Background technique [0002] In river slope protection and urban greening, vegetation ecological concrete is widely used, which can effectively prevent soil erosion and restore ecological balance. As an artificial soil technology widely used in engineering practice, polymer aggregates have stabilized slopes, repaired exposed mountains, and contributed to the restoration of ecological balance. [0003] Traditional plant-growing ecological concrete is used for surface covering soil. In actual engineering use, the surface covering soil is easily washed away by rain, or due to long-term drought and no rain, and complex soil moisture in the construction area, the final plant survival rate is low.

Problems solved by technology

[0003] Traditional plant-growing ecological concrete is used for surface covering soil. In actual engineering use, the surface covering soil is easily washed away by rain, or due to long-term drought and no rain, and complex soil moisture in the construction area, the final plant survival rate is low. Disadvantages such as high maintenance costs in the later stage: ① rainwater washes away the concrete surface covering soil and plant seeds in the covering soil, ② drought and water shortage lead to low germination rate of seeds, ③ lack of nutrients during plant growth, and the root system cannot penetrate the concrete pores and take root in the soil

The final result is that the survival rate of plants is low, and the effect of slope greening and ecological restoration cannot be achieved.
