Abstract

The invention belongs to the technical fields of road building blocks and a preparation method therefor. The invention mainly aims to solve the technical problems that a conventional foaming and coagulating building block for paving a side slope of a road cannot provide durable nutrition for plants and the durability is poor because of low compressive strength. The nutritional foaming and coagulating grass planting building block disclosed by the invention comprises a foaming and coagulating framework and a nutritional foaming and curing sludge module, wherein a groove is formed in the middle of the foaming and coagulating framework, and the nutritional foaming and curing sludge module is arranged in the groove of the foaming and coagulating framework. The preparation method comprises the following steps of: preparing foam; preparing the foaming and coagulating framework; preparing the nutritional foaming and curing sludge module; and preparing the nutritional foaming and coagulating grass planting building block. The nutritional foaming and coagulating grass planting building block disclosed by the invention has the advantages of being capable of providing the durable nutrition for the plants, and being high in compressive strength.

Description

technical field [0001] The invention belongs to the technical field of road blocks and preparation methods thereof, and in particular relates to a nutritional foaming concrete grass-planting block and a preparation method thereof. Background technique [0002] Greening around traffic lines and cities is an important task in modern traffic and urban construction. Traditional road slope protection works mostly use ordinary concrete blocks. To achieve greening on the slope protection, it is necessary to reserve a certain volume of space on the slope protection material, and place soil in it for plant growth. However, traditional concrete blocks do not have water storage and water retention capacity, let alone nutrition, and it is difficult to provide lasting nutrients for road slope greening vegetation. Soil erosion occurs, which in turn makes it difficult for plants to grow. [0003] Although foamed concrete building materials have been developed for many years, they have th...
