Air pressure parallel device for scattering materials to deep part of soil layer and method

Abstract

The invention provides an air pressure parallel device for scattering materials to a deep part of a soil layer and an implementation method. The device comprises a material scattering gun, a soil penetrating device located at the upper part of the material scattering gun, and a gas spray explosion system and a material feeding system which are separately connected with the material scattering gun,wherein the gas spray explosion system and the material feeding system in mutual parallel connection are connected with the material scattering gun, the gas spray explosion system comprises a high-pressure gas tank and a spray explosion valve, and the material feeding system comprises a material bin, a feeding valve, a valve I, a material sending bin, a valve II and a material conveying pipe which are sequentially connected with one another. And the material conveying pipe communicates with the interior of the material scattering gun. By the adoption of the device and the implementation method, various materials of fixed amounts can be evenly applied into the soil layer at any depth, a traditional mode is replaced, the operation efficiency of applying the materials into the deep portion of the soil layer is greatly improved, the cost of applying the materials into the deep portion of the soil layer is remarkably reduced, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention belongs to the technical field of spreading materials to the deep part of the soil layer, and in particular relates to an air pressure parallel device and method for spreading materials to the deep part of the soil layer. Background technique [0002] Soil is the basis of human activities and the source of human survival and development. With the rapid development of the economy and society, human activities have seriously overdrawn the carrying capacity of the soil, resulting in the compaction, degradation and pollution of the soil that nourishes us. This overdraft activity not only damages and affects the soil surface, but further damages and affects the deep soil. How to restore and improve the soil, maintain and rebuild the deep soil is currently facing the embarrassing situation that no one is willing to do manual work, there is no way to do it technically, and there is no available operating equipment. This situation is not only t...

Problems solved by technology

[0006] In the field of shallow soil restoration and improvement, the related equipment and methods of material application are mainly limited to surface application, and then the soil and materials are mixed with hoes, plowshares, shovels, excavators, forklifts and other digging tools. The defects are mainly manifested in: first, destroying the surface soil and soil aggregate structure; second, there are many factors restricting the operation, including but not limited to topography, crop types, types of materials applied, operating seasons, etc.; third, low operating efficiency , poor effect, high cost, complicated process and high labor intensity

[0007] For soil remediation and improvement in the deep soil layer, the related equipment and methods of material application are mainly limited to the process links such as drilling, injection of chemicals, high temperature and high pressure pressure, extraction treatment, etc. The existing defects are mainly manifested in: First, the type of mixed materials Restrictions, the spraying agent is limited to gas and liquid agent with permeation and diffusion, and cannot diffuse solid powder and granular substances; second, the process is complicated, the cycle is long, the investment is high, the efficiency is low, and the mixing process is uneven and incomplete; 3. The scope of application is narrow, powerless for mine restoration, desert control, groundwater pollution control, etc.
