Desertification is a serious ecological crisis that refers to the gradual transformation of land in arid and semi-arid areas into barrenness, loss of vegetation, and eventual desertification. Desertification not only threatens the survival and development of human beings, but also destroys the biodiversity and climate balance of the planet. With the increase of extreme weather, the phenomenon of desertification is becoming more and more serious, according to the United Nations statistics, the land swallowed by the desert has reached more than 2 million square kilometers in the world every year, and the traces of desert can be seen on all continents of the world.
According to statistics, the deserts of Gansu, Inner Mongolia and Xinjiang account for 90% of the total deserts in the country, taking Gansu as an example, the desertification area of the province has accounted for more than 7 percent. In the face of the ever-expanding desert, human beings have not given up the way to break the situation, but the sand in the desert is too fine and the adhesion is too weak, and it is difficult to use it as construction sand.
In order to solve this problem, Chinese scientists have designed a magical machine called the "Sand Swallowing Behemoth" after years of hard work.
It is a large construction machine that can travel freely in the desert, and it has a variety of functions and technologies that can turn the desert into a valuable resource. It is very versatile, not only to harden and fix the sand, but also to prevent the sand from blowing. Desert soils can also be directly improved to facilitate the planting of trees on desertified land, sand fixation, and even the use of sand as building materials for the construction of houses and roads.
The successful implementation of the "Sand Swallowing Behemoth" is a pioneering initiative of China in the field of environmental protection, and has also received high praise and attention from the international community. “
The core technology of the "Sand Swallowing Behemoth" is a high-energy particle beam that breaks up the sand on the surface of the desert and then turns it into a cement-like slurry. The mortar is then sucked into the machine by strong suction, shaped at high pressure, and finally turned into a strong building material that can be used to build houses, roads, bridges and other facilities.
This building material not only has good strength and durability, but also has the properties of heat insulation, sound insulation, fire prevention, etc., and is a new type of material that is environmentally friendly, energy-saving and low-cost. In 2018, Chinese scientists carried out a series of experiments in Gansu Province, where desertification is the most serious in the country, using the "sand swallowing monster" for small-scale use in Jiuquan and Jiayuguan, and has achieved remarkable results and results so far.
According to statistics, in the process of testing and promoting the "sand swallowing monster" in Gansu, the desertification area can be reduced by more than 40 acres per day, so that the desert area that a machine can handle will reach 1 per year50,000 acres, and at the same time can produce about 150,000 cubic meters of building materials.
These building materials can not only be used for local infrastructure development, but can also be exported to other regions, generating new income for local economic development**. In this way, the "sand swallowing monster" is simply an artifact to deal with desertification. It can not only effectively improve the ecological environment of desertification, increase the fertility and moisture of the land, and create favorable conditions for the restoration and growth of vegetation;
Moreover, it directly solves the age-old problem of not being able to use the fine sand in the desert, converts it into valuable building materials, realizes the recycling of resources and reduces the waste of resourcesThird, it has effectively promoted local economic and social development, increased employment opportunities and income levels, and improved people's quality of life and happiness.
The "Sand Swallowing Behemoth" is still some way from being rolled out on a large scale. In order to achieve good results, machinery will consume huge amounts of energy when running, which is a heavy burden for energy conservation and emission reduction, and in the long run, if the problem of high energy consumption is not solved, it will only transform the problem of desertification into a corresponding greenhouse effect, and it seems that the desert will actually aggravate the El Niño phenomenon.
Moreover, the machine needs to consume a lot of water in the process of operation, and the areas with serious desertification are generally drought and lack of water, and how to reduce the water consumption in the construction process is also a direction of future difficulties. Not to mention the huge cost of care and maintenance, the operation of this machine requires regular maintenance and management to guarantee its safe, stable and efficient work.
Although the Sand Swallowing Behemoth is not perfect, it still has some problems and challenges that need to be solved. For example, it uses a lot of energy when it operates, and if it uses fossil energy such as coal, oil, and gas, it will cause air pollution and increase the greenhouse effect.
But we can't deny its merits and potential. With the progress and innovation of science and technology, it is possible for us to make the "sand swallowing monster" use more environmentally friendly, efficient and sustainable energy and technology, which can reduce the impact on the environment and improve the utilization of resources. Moreover, the application prospects of the "sand swallowing monster" are not limited to the desert, but can also be used to improve the soil, prevent landslides, fill cracks, etc., so that the natural environment can be protected and restored.
