Introduction of the technology of the guest soil spraying machine

Guest soil spraying machineUse background：  

With the acceleration of urbanization in China and the gradual advancement of various development and construction projects, a large number of exposed slopes have appeared. These exposed slopes will not only have a great impact on the original soil and water conservation functions, but also cause landslides and cause great damage to the surrounding ecological environment. regular protection means such as shotcrete anchor, mortar rubble skeleton, cement skeleton and retaining wall can well support the stability of the slope, but because of its low coordination with the surrounding environment, it can not adapt to the modern urban landscape, nor can it meet the aesthetic needs of people. The soil spraying can not only realize ecological restoration, but also protect the environment. The soil spraying technology is to mix the soil with organic matrix, binder, water retaining agent, fertilizer, acid-base regulator, seeds, etc. according to a certain ratio, stir fully by machinery, and then spray the slope with the energy of the soil spraying machine to form a soil layer for plant growth on the slope. After the seeds germinate and grow into a flat, the stability of the slope can be effectively protected, thus quickly restoring vegetation and ecological barriers.

1 Basic principles of construction of soil spraying machine

Spray seeding slope protection and engineering protection, plant slope protection mechanism is different. Engineering protection mainly adopts methods such as mortar plastering, jointing, spraying, stone slope protection or surface protection to reinforce and stabilize unstable rock or soil slope. The purpose of beautifying the road appearance and coordinating the surrounding environment is achieved through measures such as grass planting, turf laying and tree shrub planting. At the same time, the stability and erosion resistance of the relatively gentle stable soil slope are improved to a certain extent through measures such as plant culvert water and soil fixation, shallow root reinforcement and deep root anchoring. Obviously, the guest soil spraying is different from the engineering protection which is extremely discordant with the surrounding environment, and also different from the only plant protection measures on the gentle soil slope, but this is not a combination of the two. This method is mainly aimed at the stable rock slope, hard soil slope and special soil slope which are not suitable for plant growth, and its essence is to create "soil" artificially, to create the foundation for the settlement and growth of plants, so as to achieve the purpose of greening the barren slope. However, as a kind of flexible shallow surface slope protection, its slope protection mechanism includes two aspects besides closely connecting the anchor rod and the hanging net to maintain the stability of the surface soil: one is the plant community formed on the slope, which uses measures such as precipitation interception and plant leaf system barrier to reduce the erosion of rainfall on the slope, and can slow down the speed of rainfall and reduce the erosion of rainfall, isolating the rock mass from the external environment can effectively slow down and inhibit the weathering and spalling of the rock mass under natural conditions.
