Embodiment 1
[0041] An improved soil saturated hydraulic conductivity detection method is carried out according to the following method:
[0042] S1. Sample collection: collect the undisturbed soil with the sample ring knife (53), and bring the collected undisturbed soil back to the laboratory;
[0043] S2. Soaking and saturation: soak the sample ring knife 53 24 hours before testing the saturated hydraulic conductivity; install a filter paper of suitable size in the hole cover on one side of the sample ring knife 53, and install a non-porous cover on the other side, and place it Soak in water, the end of the sample ring knife with the hole cover is facing down, and the water level should not pass through the hole cover; avoid too little water to completely soak and saturate;
[0044] S3. Adjustment level: adjust the overall level of the improved soil saturated hydraulic conductivity detection device through the level adjuster; it is also possible to adjust the entire improved soil saturat...
Embodiment 2
[0061] Such as figure 1 and figure 2 The hydraulic conductivity detection device shown includes a support plate I1, a support plate II2 fixedly connected to both sides of the support plate I1, a water container 5 fixed between the two support plates II2; A plurality of sample receivers 54 for placing the sample ring knife 53, the bottom of the sample receiver 54 is connected with a ∽ tube, one end of the ∽ tube passes through the water container 5 and communicates with the latex tube 4, the latex tube 4 The lower end passes through the clamping structure 3 arranged below the water container 5 and extends into the water receiving container 6 . The clamping structure 3 controls the on-off of the liquid in the multiple latex tubes 4 at the same time. The top of the water-receiving container 6 is a constriction, and the lower end of the latex tube 4 is inserted into the constriction, so as to avoid water evaporation and splashing during the experiment to make the detection data ...
Embodiment 3
[0064] On the basis of Example 2, such as image 3 The clamping structure shown includes a first clamping plate 32 and a second clamping plate 34, the two sides of the first clamping plate 32 are fixedly connected with the supporting plate II2 on both sides of the supporting plate I1, and the two sides of the second clamping plate 34 are connected with the supporting plate II2. The supporting plate II2 on both sides of I1 is movably connected, and the two sides of the first clamping plate 32 and the second clamping plate 34 are connected by a spring 33, and the opposite surface of the first clamping plate 32 and the second clamping plate 34 is provided with a latex tube 4 to pass through. The groove 321 passed through, the second splint 34 is provided with a protrusion 341 that matches the groove 321; a timing assembly is arranged between the first splint 32 and the second splint 34, and the timing assembly is used to check the passage of time. The time of the experimental wat...
