Grass planting concrete construction based on herbal root system architecture and fabrication method of grass planting concrete construction

Abstract

The invention discloses a grass planting concrete construction based on a herbal root system architecture and a fabrication method of the grass planting concrete construction. The grass planting concrete construction comprises a grass planting concrete multilayer structure; the concrete construction is divided into 2-4 layers according to root system density and a natural rootstock growth rule; the total thickness is 10-15cm; the porosity of the grass planting concrete construction is 10-35%; and the grass planting concrete construction is prepared from the following raw materials in parts byweight: 113-313 parts of cement, 1421-1568 parts of coarse aggregate, 113-313 parts of fine aggregate, 2-10 parts of hardening agent, 0.23-0.63 parts of water reducer and 29-95 parts of water. The fabrication method gives a comprehensive consideration from microstructure features and physiologic growth feature parameters of vegetation, and contributes to providing scientific and good growing spaceand growing conditions for plant root system growth; the growth activity and a coverage rate of herbal plants in concrete are improved and increased; the tensile strength, fracture strength, bendingresistance and reversed filter performance of the concrete are improved; and a herb-concrete-soil complex adapted to the natural plant growth rule is formed.

Description

technical field [0001] The invention relates to ecological engineering technology, in particular to a grass-planting concrete structure based on the configuration of the herb root system and a preparation method thereof following the natural growth law of the herb root system. Background technique [0002] Under the background of the extremely arduous task of ecological construction in our country, it is more and more urgent to apply biological measures to ecological protection of engineering measures. Therefore, the promotion and application of ecological technologies and products combining concrete and herbal plants has great application prospects, space and markets. . [0003] Since the 1990s, the Japan Concrete Engineering Association has proposed the concept of ecological concrete. At present, scholars are mainly conducting research on the macroscopic physics, mechanics and planting performance of grass-planted concrete. The so-called grass-planting concrete is a kind ...

Problems solved by technology

However, compared with the herbs that grow naturally in the soil environment, grass-planted concrete has a special random pore structure, which has a certain restrictive effect on the growth of herbs.

The mechanical strength and structural pores of grass-planting concrete are contradictory. When the particle size and pores are large, although it is beneficial to plant growth, the compressive and flexural strength will decrease; the particle size is small, the pores are small, and the strength increases. Large but unable to meet the needs of plant root growth, which reduces the survival rate and growth vigor of herbs, and weakens the overall performance of the "herb-concrete-soil complex"
