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

Abstract

The invention provides an ecological recovery method with combination application of vegetation concrete and high-molecular aggregates, and is applied to fields of riverway slope protection engineering, ecological recovery engineering, garden greening engineering and the like. The ecological recovery method comprises the following steps: first, vegetation concrete is prepared; second, high-molecular aggregates are prepared; third, a riverway or a slope is cleaned to meet construction requirements, a layer of nutrition earthwork cloth is laid on a construction surface first, then the vegetation concrete and high-molecular aggregates are mixed and stirred for half hour completely, and then subjected to pouring on the earthwork cloth, and the pouring thickness is 10-15 cm; fourth, after the vegetation concrete is poured for 4h, watering curing is started, according to local climate change, the curing state with water every day is kept until plants sprout, and then curing is continued for half month to a month. The problems that plants cannot survive because of too high dosage of vegetation concrete cement and the anti-scouring property of vegetation concrete is not enough because of too low dosage of cement are solved.

Description

technical field [0001] It is used in river slope protection engineering, ecological restoration engineering, landscaping engineering and other fields. Background technique [0002] Vegetation concrete is a new ecological protection technology that uses specific concrete formula and mixed green seeds to protect and green rock slopes. 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] After the matrix of the vegetation concrete is solidified, it has a certain mechanical strength without cracking, scouring or loss. However, cement is added in this technical method. If the amount of cement is small, it is not enough to make the matrix achieve sufficient strength. If a large amount of cement is added for construction strength, grass cannot survive. In previous constructions, the method of adding vegetation concrete greenin...

AI Technical Summary

Problems solved by technology

In previous constructions, the method of adding vegetation concrete greening additives was used to increase the fertility of the substrate and reduce the alkalinity of the concrete, so that the vegetation concrete is more suitable for plant growth, but this method is not used to excessively reduce the alkalinity of the cement, otherwise The mechanical strength of concrete does not meet the requirements, and cracks will also occur. When the two sides reach a balance, the varieties of plants that can adapt to growth are limited.
