Hydraulic ring investigation sampling device

Abstract

The invention discloses a water conservancy project environment investigation sampling device, and relates to the field of water conservancy project environment investigation sampling devices. A steam collecting chamber, an initial screening chamber, a first mixing chamber, a second screening chamber, a second mixing chamber, a third screening chamber, a heating chamber and a water collecting chamber are arranged in the sampling and separating box from top to bottom. Then the sealing door assembly covers the front side of the sampling and separating box to seal the sampling and separating box, the interior of the sampling and separating box is heated through the heating unit, and a soil sample in the sampling and separating box is dried; water vapor generated in the drying process can completely enter the steam collecting chamber through the water vapor collecting assembly to be condensed, the condensed water flows into the water collecting chamber from the communicating channel to be collected, and the water content of the soil samples can be obtained.

Description

technical field [0001] The invention relates to the field of survey and sampling devices for hydraulic environment, in particular to a survey and sampling device for hydraulic environment. Background technique [0002] The hydraulic ring refers to hydrogeology, engineering geology and environmental geology. Hydrogeology is the science that studies groundwater. It mainly studies the distribution and formation of groundwater, the physical properties and chemical composition of groundwater, groundwater resources and their rational use, and the adverse effects of groundwater on engineering construction and mining and its prevention and control. Engineering geology is the science of investigating, researching, and solving geological problems related to human activities and various engineering buildings. [0003] However, when the existing hydraulic and environmental geological survey sampling devices detect the different coarse and fine particle components and moisture content ...

Problems solved by technology

[0003] However, when the existing hydraulic and environmental geological survey sampling devices detect the different coarse and fine particle components and moisture content contained in the soil sample, they often take out part of the soil and use a humidity sensor to detect the humidity, so as to obtain the moisture content in the soil, and then pass Part of the soil is separated to obtain the content of different coarse and fine particle components, while the water in part of the soil continues to volatilize, and the soil contained in each part may be inconsistent, and the different coarse and fine particle components in each part may also be inconsistent, which leads to poor detection accuracy.
