Soil lossless sampling construction technological process

Abstract

The invention discloses a soil lossless sampling construction technological process which comprises the following steps: S1, early-stage preparation: determining a suitable drilling method and sampling equipment according to a stratum structure, a drilling depth, a collected sample type and the like, performing technical disclosure with a drilling unit and a detection unit, and determining task division and requirements; S2, sampling time determination: determining the sampling time according to soil conditions and recent weather conditions; S3, determining a sampling range: determining underground conditions of an underground tank, a pipeline, a water collecting well and an inspection well at the lower part of the sampling device before soil drilling, and ensuring sampling safety. According to the device, field sampling can be well carried out, the influence of weather reasons on sampling can be effectively avoided, the sampling accuracy is ensured, the sampling quality is improved, and therefore accurate monitoring can be conveniently carried out, and the soil condition can be known.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a construction process flow of soil non-destructive sampling. Background technique [0002] The collection of soil samples is the basic work in the field of soil science research and geological exploration, which provides a material basis for the determination of the physical and chemical properties of soil samples. [0003] Clarifying the composition and concentration of soil pollutants is the basic premise for formulating soil pollution control measures, and soil sample collection and analysis are the basic means to obtain soil physical, chemical, biological properties and composition characteristics. The soil sampler is one of the necessary tools for soil sample collection. The quality of its sampling performance determines the quality of the sampling, which is closely related to the accuracy and reliability of the final obtained data.

Problems solved by technology

[0004] Soil sampling tools currently on the market are too simple in structure, and often use sampling tools similar to Luoyang shovels, which are inaccurate in positioning the sampling depth, or cause the sample to be taken to separate during the sampling extraction process, resulting in sampling failure, and can only be re-sampled at another location ; and when multiple sampling is required, the sampling tool can only be repeatedly probed and taken out once and for all, resulting in a waste of personnel energy and time, and the sampling accuracy is not accurate enough, which seriously affects the follow-up soil sample analysis. And its large excavation range will cause the vegetation layer of the sampling site to be destroyed. Therefore, we propose a soil non-destructive sampling construction process to solve the above problems
