Abstract

The invention discloses a method for utilizing solar energy for fixing sand. The method utilizes a convex lens for focusing solar radiation and generates high temperature at a focus point for meltingsand particles for producing block-shaped sand bricks. The large-area coverage of the block-shaped sand bricks on a sand dune can thoroughly prevent desert from flowing and prevent dust storm. The method comprises the following steps: producing a special tool and utilizing optical materials for producing the convex lens with a support which can adjust direction. The convex lens is arranged on thesupport, and the direction of the support is adjusted, thereby melting the sand particles at the focus point of the convex lens for forming the big sand bricks. The large-area coverage of the sand bricks on the surface of the sand dune can achieve the purpose of fixing the sand.

Description

Technical field: [0001] The invention belongs to the physical method of quicksand fixing engineering in desert area, and also relates to solar energy application technology. Background technique: [0002] With the warming of the climate and the over-exploitation of land by humans, the desert area of ​​the earth's land is gradually expanding, swallowing up large areas of green land and farmland suitable for human survival. The governance of the desert has raised a major and difficult problem for human beings. [0003] Our country is one of the countries with serious sand damage. Several large deserts are threatening the survival of people around the deserts after they flow due to wind force. Governments at all levels of the country are vigorously carrying out sand prevention and sand fixation projects, and their budgets are huge. At present, sand control projects basically adopt two types of biological methods and physical methods. The plant method of planting a large numbe...
