Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a soil sample packaging and sealing device for earthquake zone survey sites. Background Art

[0002] Soil composition is complex. Generally speaking, it consists of three phases: solid, liquid, and gas: minerals, organic matter from the decomposition of plant and animal debris, water, and air. China's soil resources are rich and diverse, a rare find in the world.

[0003] During seismic soil monitoring, representative values ​​of factors affecting soil environmental quality are measured to determine soil environmental quality and its changing trends. During the testing process, the sampled soil needs to be classified and stored. However, in existing technologies, workers often use disposable sealed bags to store soil samples. The sealed bags used to store soil samples have poor sealing properties, and soil samples are prone to oxidation, which reduces the integrity of soil sample storage and the accuracy of soil sample testing. Stacking multiple sample bags filled with soil will make sample extraction and access difficult, and will also result in waste of sealed bags, creating an environmental burden. To this end, we provide a soil sample packaging and sealing device for earthquake zone survey sites. Utility Model Content
