Soil remediation sampler for stratified sampling of soil

Abstract

The invention discloses a soil remediation sampler for stratified sampling of soil. The invention relates to the technical field of soil remediation. The soil remediation sampler for stratified sampling of soil comprises a sampling main cylinder, an air groove is annularly formed in the inner side wall surface of the sampling main cylinder, an inner cylinder is arranged on the inner side of theair groove; an extrusion transmission groove is annularly formed in the side wall of the top of the inner side of the inner cylinder; according to the soil remediation sampler for stratified samplingof soil, after Sampling is finished, a lower rod is controlled by control equipment to be lifted up; therefore, an extrusion block on the gas control equipment ascends and extrudes the interior of the inner cylinder to extrude gas above the extrusion block; the air groove, the extrusion transmission groove and an inflation groove are used for conducting, so that the air above the extrusion blockis impacted and extruded into a closed air bag on a closed device, the closed air bag is inflated and expanded to be reset and closed, and the effect of completely taking out sandy soil is achieved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a soil remediation sampler for layered sampling of soil. Background technique [0002] As the understanding of the ecological environment becomes clearer, the methods of environmental protection are gradually implemented. When adopting environmental protection methods, the most common way is usually the planting and cultivation of green plants, so as to improve and enhance the regional ecology, while some The soil quality in the area will be damaged, and soil restoration needs to be carried out in a targeted manner. Therefore, it is usually necessary to sample and analyze the soil in advance during soil restoration, so that the soil can be targeted for adaptive restoration. However, due to regional Some soils are in the shape of loose sand, and the conventional sampling method for this type of soil will easily cause the soil to be separated from the sampling container in...

[0002] As the understanding of the ecological environment becomes clearer, the methods of environmental protection are gradually implemented. When adopting environmental protection methods, the most common way is usually the planting and cultivation of green plants, so as to improve and enhance the regional ecology, while some The soil quality in the area will be damaged, and soil restoration needs to be carried out in a targeted manner. Therefore, it is usually necessary to sample and analyze the soil in advance during soil restoration, so that the soil can be targeted for adaptive restoration. However, due to regional Some soils are in the shape of loose sand, and the conventional sampling method for this type of soil will easily cause the soil to be separated from the sampling container instantly after being taken out, thus making it impossible to complete the sampling operation. Therefore, we propose a soil remediation sampler for stratified sampling of soil
