Description
Technical Field
The invention relates to the technical field of cliff wall soil sampling equipment, in particular to cliff wall soil texture analysis sampling equipment for civil engineering.
Background
Civil engineering is a general term for scientific technology for building various land engineering facilities. It refers to both the materials, equipment used and the technical activities carried out such as surveying, designing, construction, maintenance, repair, etc., as well as the objects of engineering construction. I.e. various engineering facilities such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, ocean platforms, water supply and drainage and protection projects, which are built on or under the ground, on land and directly or indirectly serve human life, production, military affairs and scientific research.
Along with the development of society, the engineering structure is increasingly large and complex, super high-rise buildings, super large bridges, huge dams and complex subway systems are continuously emerged to meet the living demands of people, and meanwhile, the engineering structure is also transformed into a sign of social strength.
Civil engineering needs are related to soil texture analysis. Soil texture analysis, i.e., soil analysis, is a qualitative and quantitative measurement of the composition and/or physical and/or chemical properties of soil. The method is a basic work for carrying out soil generation and development, fertility evolution, soil resource evaluation, soil improvement and reasonable fertilization research, and is also an important means for carrying out environmental quality evaluation in environmental science.
The soil is a complex multi-phase system consisting of three phases of solid, liquid and gas. The soil solid phase comprises mineral matters, organic matters and soil organisms; between the solid phase materials are pores of different shapes and sizes, in which moisture and air are present.
The soil is mainly solid, and three phases coexist. The relative contents of the three-phase substances vary depending on the kind of soil and environmental conditions. The three-phase substances are mutually linked and restricted, and are connected with the atmosphere at the upper part and the underground water at the lower part to form a complete multi-medium multi-interface system.
A cliff is an exposed rock that is perpendicular or nearly perpendicular, and is a terrain that is eroded, weathered.
Cliffs are formed by construction activities, water movement, weathering, erosion and glacier activities. Earthquakes and landslides also form cliffs. Cliffs tend to form on shore, in mountainous areas, along rivers or as walls of canyons. Some cliffs are formed because when structural plates under the earth surface rub together due to the action of the internal force of the earth, one or two plates are pushed upwards by the pressure, so that earthquake and landslide are caused, and faults are generated; some are caused by landslides or collapses; also some are due to sea wave erosion; in addition, the cliff can be formed by the mining of rocks, engineering blasting and the like in the mountains of human beings.
The method is used for analyzing the soil quality of the cliff wall and is beneficial to the research of geological activities at the cliff wall.
However, as is known, the cliff has a large angle, and if the cliff climbs manually to fetch soil, the acting point is limited, so that the soil fetching work is very difficult, and the life risk also exists. In the prior art, the number of sampling devices specially used for cliff wall soil quality analysis is small, so that the sampling device for cliff wall soil quality analysis for civil engineering needs to be designed to complete cliff wall soil sampling work.
