Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering investigation, and more specifically to a geotechnical engineering investigation borehole water level measuring device. Background Art

[0002] Soil is a general term for any kind of rock and soil that makes up the earth's crust from the perspective of engineering and construction. Rock and soil can be subdivided into five categories: hard (hard rock), sub-hard (soft rock), weakly connected, loosely unconnected, and with special composition, structure, state and properties. In China, the first two categories are called rocks and the last three are called soil. The collective name is "rock and soil". In geological exploration, a cylindrical circular hole with a small diameter and a large depth drilled underground by drilling equipment is also called a well. Water level refers to the elevation of the free water surface of the water body above the fixed base surface, and its unit is meter. The water level measurement in the borehole is to measure the water level in the borehole to provide data for subsequent projects.

[0003] The working environment of geological exploration is not only on the ground, but sometimes it needs to be carried out inside caves. At the same time, geological exploration is also needed during the mining process of mines. However, the rock exploration borehole water level measuring instrument in the existing technology is in the form of a cart. The space for working in caves and underground is originally small. The water level measuring instrument in the form of a cart is not only difficult to operate, but also occupies a large space, making it inconvenient to enter and exit caves and mines.

[0004] After searching, a Chinese patent with application number CN202322131253.X discloses a geotechnical engineering survey borehole water level measuring instrument, which can disassemble the positioning sleeve on the rotating rod to the positioning plate. During use, the entire device can be disassembled and assembled, which makes it more flexible and convenient to carry during use.

[0005] When the above-mentioned geotechnical engineering survey borehole water level measuring instrument is actually used, a large amount of dust, soil or other impurities may accumulate on the measuring device during geotechnical engineering survey. The accumulation of dust and dirt may aggravate the wear or damage of the measuring device, resulting in distorted or inaccurate measurement data. Utility Model Content
