Description

Technical Field

[0001] This utility model relates to the field of soil improvement auxiliary equipment technology, specifically a soil profile ruler for improving contaminated soil. Background Technology

[0002] Soil profile gauges are core tools in contaminated soil remediation. They need to accurately measure the thickness of soil layers at different depths and locate the distribution of contaminated soil layers to provide data support for the selection of remediation technologies, application of amendments, and evaluation of effects. However, existing soil profile measurement tools have many shortcomings and cannot meet the precision requirements of contaminated soil remediation.

[0003] Insufficient verticality calibration accuracy: Patent CN220853349U discloses an improved soil profile ruler, which uses a traction rope and a weight block to cooperate with the positioning groove on the support to calibrate verticality. However, it can only achieve alignment of a single plane and cannot ensure that the ruler body is perpendicular to the horizontal plane, resulting in a large measurement error. In addition, it lacks an auxiliary positioning structure, and the ruler body is prone to tilting.

[0004] Insufficient rigidity and stability: Patent CN219551337U discloses a telescopic flexible ruler for soil profile measurement. The telescopic flexible ruler is prone to elongation and deformation due to counterweight traction. At the same time, it is easily shaken by the influence of wind and other field environments, which further reduces the measurement accuracy.

[0005] Limited adaptability: Some traditional rigid profile rulers have fixed lengths and cannot be flexibly adjusted according to the depth of the soil profile, making it difficult to cover the diverse measurement needs of contaminated soil from shallow (<1 meter) to deep (>2 meters).

[0006] To address the shortcomings of the existing technologies, there is an urgent need to design a soil profile ruler for remediating contaminated soil that is highly accurate in verticality, adaptable, and stable. Utility Model Content

A flat plate 18 is installed in the guide bracket 13 with adjustable height. A first hand-tightening bolt 20 is installed through a threaded hole at the bottom of the flat plate 18. A support plate 21 is installed on the top of the first hand-tightening bolt 20. A rectangular guide frame 17 is provided at the top of the guide bracket 13. The inner contour of the rectangular guide frame 17 is adapted to the outer contour of the first ruler body 1 and the extended ruler body 4. Scale strips are provided on the first ruler body 1, the extended ruler body 4 and the guide bracket 13.

[0025] By adopting the above-described scheme, in use, after selecting a suitable and skilled extension ruler 4 according to the depth of the excavated soil profile, the first ruler 1 and several extension rulers 4 are sequentially connected through the cooperation of the locking block 5, the locking groove 6, and the limiting mechanism. Then, the guide bracket 13 is fixed to one side of the bottom of the soil profile, and the plate 18 is adjusted to an appropriate height within the guide bracket 13. Finally, the lowest extension ruler 4 is passed through the rectangular guide frame 17, and the locking block 5 at the bottom of the extension ruler 4 abuts against the support plate. 21. Then observe the first circular bubble level 3 to straighten the first ruler 1 so that it is perpendicular to the horizontal plane. Then rotate the first hand-tightening bolt 20 to fine-tune the height of the support plate 21 so that the zero mark of the first ruler 1 is aligned with the top of the soil profile.
