Sand-fixing plant-growing hollow brick and preparation method thereof

Abstract

The invention discloses a sand-fixing plant-growing hollow brick. The sand-fixing plant-growing hollow brick comprises the components prepared from the following raw materials in percentage by weight: 40 to 70% of coagulator, 20 to 50% of desert sand, 2 to 10% of water-retaining agent, 4 to 10% of straw fibers, and 0.2 to 0.5% of foaming agent. The hollow brick can be piled to a desert area to effectively resist quicksand moving; vegetation can be planted in a hollow brick body; the brick body has the characteristics of water absorption, water retention and breathability based on the special matching, thus good conditions are provided for psammophytes to grow in the hollow space; the desert of a large area can be comprehensively treated and greened quickly and effectively so as to prevent from water and soil loss, and as a result, the ecological environment can be improved, and the economic benefits and social benefits are obvious.

Description

technical field [0001] The invention relates to the technical field of desertification control, in particular to a sand-fixing and plant-growing hollow brick and a preparation method thereof. Background technique [0002] Land desertification is one of the most serious ecological and environmental problems in the world today. According to the latest data, the desertified land area in my country is 2.6237 million square kilometers, and the desertified land area is 1.7311 million square kilometers, accounting for 27.33% and 18.03% of the total land area respectively. In recent years, the ever-intensifying sandstorms and the expansion of desertified land have made the ecological environment worse, and the living space of the people has been continuously reduced, which has caused great harm to social and economic development. [0003] At present, the main methods of desert control at home and abroad include biological sand fixation, physical sand fixation and chemical sand fixat...

AI Technical Summary

Problems solved by technology

In desertified areas, due to the slow growth of plants, it is difficult to achieve single biological sand fixation, while the physical sand fixation technology based on setting up sand barriers is relatively expensive and can only work at short distances. Sand barriers with a height of tens of centimeters will be submerged and filled in less than 2 to 5 years, and the effective time is short

At present, chemical sand fixation is difficult to be widely applied due to its high cost, poor environmental adaptability, and some sand fixation materials will cause secondary pollution to the environment.
