Soil monolith acquisition and production equipment and technology

Abstract

Soil monolith acquisition and production equipment and a technology belong to experimental research equipment for soil monolith acquisition and production and operational technical specification, and can well solve the problem that a soil sample is easy to crack and collapse, bonding strength of a produced sample is not high, mechanical material is easy to fall and soil structure is easy to destroy during sampling in the field by present equipment and technologies. The equipment provided by the invention is mainly composed of a soil sampling frame, a supporting auxiliary plate, a base plate, a cover plate, an auxiliary frame, gauze, a cementing agent and the like. Detailed implementation way of the invention comprises two stages of field sample acquisition and lab sample treatment, including more than 10 technical steps. By the adoption of the equipment and the technology to produce the soil monolith, original genetic state of an earth pillar can be retained to the maximum, and the earth pillar has characteristics of large stretching surface, thin thickness, light weight, high strength and the like.

Description

technical field [0001] The patent of the present invention relates to a kind of equipment and technology for collecting and making the whole section of soil samples. The whole section of the soil sample after making can better maintain the original structure, layer differentiation and morphological characteristics of the vertical section of the soil, and the sample has good consolidation and hardness, which can be preserved and displayed for a long time. Background technique [0002] The whole soil sample is a longitudinal section sample from topsoil to core soil, across the entire soil profile, which is often used for scientific research, teaching, archiving and popular science display after collection and production. Compared with other forms of soil samples, the collection and manufacture of whole soil samples is difficult, costly, and easily damaged. The main tool for traditional soil sample collection is a wooden frame with a length of about 100cm and a width of about ...

AI Technical Summary

Problems solved by technology

Since this kind of sample collection equipment cannot effectively support the facade of the soil column, the sample is easily broken and collapsed when the soil is peeled off

In the subsequent specimen preparation process, it is usually fixed on the bottom plate (the bottom plate is wood, particleboard or fiberboard with the same size as the specimen) after drilling and dipping. This treatment method is easy to cause damage to the specimen. And only rely on the adhesive force of the cement to bond the specimen to the bottom plate, without structural protection measures

On the one hand, in the process of transportation and under the action of its own gravity in a static state, the sample is prone to integral shedding and fracture; on the other hand, the surface of the specimen is prone to mechanical material shedding and soil structure damage due to changes in external environmental temperature and humidity
