Description

Technical Field

[0001] The utility model relates to the technical field of rock and soil investigation water level, in particular to a rock and soil investigation water level measuring device. Background Art

[0002] In the process of geotechnical engineering investigation, when conducting geotechnical water level exploration, the investigation site is generally drilled with drilling equipment first, and then the water level measuring head is extended into the groundwater through the drilled investigation hole to measure the water level in the geotechnical layer.

[0003] In practice, the measuring device may be affected by uneven ground or complex geological conditions within the survey hole. If the rock surface to be measured is uneven, tilted, or wobbles, the guide wire securing the measuring head can easily collide with protruding rocks within the survey hole. Over time, the wire can break, causing the measuring head to fall into the hole and damage the measuring device. Furthermore, the measuring head may collide with the inner wall of the survey hole, or loose sand and gravel from the inner wall may fall and hit the measuring probe, which can easily damage the probe.

[0004] Several measures are typically taken to improve measurement accuracy and reliability: Strengthening the measuring device: Use stronger, more durable materials for the measuring head, ensuring it can withstand certain impact forces. Improving the guide wire material: Use high-strength, wear-resistant rope or wire as the guide wire to increase its tensile strength and service life. Using a guide tube: Whenever possible, drill a straight, smooth guide tube before measuring to prevent the guide wire from colliding with the rock during measurement.

[0005] However, there is a need to provide a geotechnical survey water level measuring device with increased stability to reduce tilting and shaking caused by uneven ground. Summary of the Invention
