[0034] As a further embodiment, two threaded rods 7 are fixedly arranged on the installation table 3. Two connecting ears 9 are provided on the top tank 5. The two threaded rods 7 can pass through the connecting ears 9. A threaded sleeve 8 for pressing and connecting the connecting ears 9 is provided on each threaded rod 7.

[0035] As a further embodiment, the clamping assembly further includes a second retaining ring 10 fixedly arranged on the inner circumferential surface of the top tank 5. The inner ring of the second retaining ring 10 is fixedly connected to the track housing 11. A track 12 is provided on the inner circumferential surface of the track housing 11. A top clamping member 14 is rotatably connected inside the track housing 11. The middle of the top clamping member 14 is fixedly connected to the outer ring of the bearing 23, and the inner ring of the bearing 23 is fixedly connected with a first magnetic block 22.

[0036] As a further embodiment, the top clamping member 14 is in the shape of multiple rods connected by a ring. One of the rods of the top clamping member 14 is fixedly connected with a counterweight slider 13, and the remaining rods of the top clamping member 14 are connected with sliders 21. The counterweight slider 13 and the slider 21 slide in the track 12.

[0037] As a further embodiment, a second magnetic block 20 is provided in the middle of the bottom support member 18.

[0038] As a further embodiment, a sealing ring 19 is provided at the opening of the inner circumferential surface of the top tank 5, and the upper end of the slip ring 17 is in an arc shape.

[0039] As a further embodiment, the lower end of the top clamping member 14 is higher than the lower end of the track housing 11. The top clamping member 14 does not directly contact the geotextile and does not compress the standard sand, ensuring accurate test results.

[0040] As a further embodiment, an operating platform 2 for controlling the driving module is provided on the workbench 1.

[0041] A method for determining the effective aperture of a geotextile, which is used in conjunction with a geotextile effective aperture measuring instrument as claimed in claim 1, the specific steps are as follows:

[0042] S1: Remove the threaded sleeve 8, take out the top tank 5, and open the cover 6;

[0043] S2: Cut the geotextile to be tested and place it flat on the bottom tank 4. Position the top tank 5 under the cover through the threaded rod 7 and tighten the threaded sleeve 8;

[0044] S3: During the process of tightening the threaded sleeve 8, the second magnetic block 20 is attracted by the first magnetic block 22, driving the geotextile to move towards the top clamping member 14 together until the second magnetic block 20 and the first magnetic block 22 attract and fit together to clamp the geotextile. At this time, the arc surface of the slip ring 17 cooperates with the sealing ring 19 to clamp the geotextile. Due to the different thicknesses of the geotextile, this design can adapt to geotextiles of different thicknesses. At the same time, the bottom of the track housing 11 and the top of the slip ring 17 also seal the edge of the geotextile, and the edges of the top tank 5 and the bottom tank 4 clamp the outer circle of the geotextile, forming three clamps to avoid sand leakage;

[0045] S4: Observe the compaction state of the geotextile through the top of the top tank 5, and then add the weighed standard sand into the top tank 5;

[0046] S5: Tighten the cover 6, set the working time through the operation console 2, and start the detection. During the detection process, as the installation table 3 shakes, due to the existence of the counterweight slider 13, the top clamping member 14 will start to rotate. During the rotation process, the standard sand in the top tank 5 will be continuously spread out to avoid the aggregation of the standard sand, promote the more uniform distribution of the standard sand, and avoid the situation where the standard sand in the traditional detection equipment moves along the edge with the vibration;

[0047] S6: After the detection is completed, remove the threaded sleeve 8, take out the top tank 5 and the bottom tank 4 as a whole, lift the top tank 5. At this time, the first magnetic block 20 and the second magnetic block 22 still maintain the adsorption state and do not release the clamping of the geotextile. Pour out the standard sand in the bottom tank 4 for weighing to obtain the test result. Then continue to drag the top tank 5 to open the clamping state of the first magnetic block 20 and the second magnetic block 22, and take out the geotextile and the standard sand on the top.

[0048] The above are only the embodiments of the present invention, and do not limit the patent protection scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
