Slope-protective plant-growing type pitch blend containing planting matrix and preparation method and application for same

Abstract

The invention discloses a slope-protective plant-growing type pitch blend containing planting matrix and preparation method and application for the same. The blend comprises pitch material and planting matrix. The pitch is made of the following compositions by parts: 80 to 84 parts of rock pitch, 7 to 8 parts of epoxy resin, 1 to 4 parts of methylhexahydrophthalic anhydride, 1 to 4 parts of hydrophilic assistant; the planting matrix is made of the following compositions by parts: 3 to 5 parts of vermiculite powder, 4 to 6 parts of perlite powder, 2 to 4 parts of Carboxymethylcellulose sodium, 4 to 7 parts of soilless culturing nutrient solution, 1 to 3 parts of ferrous sulfate, 58 to 64 parts of nutrient soil, 8 to 11 parts of long-acting organic composite fertilizer, 1 to 5 parts of kieselguhr and 2 to 6 parts of coal cinder; and the pitch is immersed into the planting matrix or the planting matrix is poured on the pitch. The slope-protective plant-growing type pitch blend containing planting matrix is advantaged by great durableness, vigorous plant production and strong adaptability.

Description

technical field [0001] The invention relates to an environment-friendly vegetation type asphalt mixture, in particular to a slope protection vegetation type asphalt mixture containing a planting substrate and a preparation method thereof, which is mainly used for greening and protection of surfaces such as buildings, urban municipal engineering slope structures, and slope protection on both sides of rivers. Background technique [0002] In recent years, with the continuous development of our country's social economy, the large-scale and unprecedented number of civil engineering construction activities carried out in major and medium-sized cities have caused a load on the environment that cannot be ignored. Traditional roads, harbors, revetments and other engineering components are generally composed of concrete made of cement, stone, steel, sand and other materials. They are closed and impermeable, and plants cannot grow. This completely destroys the natural water and soil en...

Problems solved by technology

[0004] Among the existing plant-based mixtures of the same type, the invention patent of the plant-based substrate formula and structure of slope protection vegetation concrete (200410022453.0) provides a simple structure, easy to prepare, good water retention performance, and anti-scouring vegetation concrete for slope protection. Although the material formula and structure can meet the requirements of river bank slope protection, the durability of concrete under the immersion and erosion of river water cannot be fully guaranteed, and the pores required for grass planting are not easy to control in concrete blocks, and the growth of plants is not vigorous.

Invention patent A kind of plant medium for greening vegetation on mountain (200510047466.8) mainly considers the unfavorable factors of vegetation growth in the mo
