[0002] The static sounding for geotechnical engineering investigation is an in-situ testing method widely used in the field of geotechnical engineering, which is used to evaluate the physical and mechanical properties of foundation soil. By vertically pressing the probe rod with a cone head into the ground at a constant speed and measuring the resistance encountered during insertion, important information about soil strength, density and layering can be obtained.

[0003] The existing static sounding for geotechnical engineering investigation usually fixes the probe rod on the extension rod by screw connection first, then splices the extension rod according to the requirements, and then inserts the probe rod into the soil for testing. However, due to the need for multiple rotations of the extension rod for splicing and fixing by screw connection, it cannot be quickly spliced and fixed, the operation is cumbersome, and the efficiency is low.

[0004] Therefore, it is necessary to design a static sounding device for geotechnical engineering investigation that can quickly splice and fix the extension rod, is simple to operate, and improves work efficiency. SUMMARY

[0007] As a further preferred scheme, the lower part of the plug rod is conical.

[0008] As a further preferred embodiment, the probe assembly includes a probe rod, an extension rod, a second motor, a first bidirectional lead screw, a second sliding frame, and a clamping rod. The second motor is connected to the right side of the first sliding frame, and the first bidirectional lead screw is connected to the output shaft of the second motor.

The operation is simple and improves the work efficiency.

[0013] 2. This utility model moves the probe downwards, causing it to contact the guide wheel and rotate, thus inserting the probe into the ground for static penetration testing. The guide wheel limits the probe's position, achieving the effect of limiting and guiding the probe during static penetration testing, preventing probe deviation from affecting the test results.

[0014] 3. This utility model achieves the effect of scraping off the soil on the surface of the probe rod and extension rod by moving the probe rod and extension rod upward and scraping it off with a scraper. This prevents the soil from re-entering the next test point and affecting the accuracy of the test results. Attached Figure Description
