Geotextile effective pore size measuring instrument for the determination of effective pore size of all types of geotextile products - Database & Sql Blog Articles

The geotextile effective aperture measuring instrument is composed of a bottom plate, a cover, a holder, a screening device, a shower system and the like. The four corners of the bottom plate are provided with mounting slots, which can be fixed on the foundation or the worktable by bolts; the control area of ​​the upper left corner of the cover is equipped with a counter, a power switch and a start button. The cover and the screening vibration device are not in direct contact, reducing the effects of vibration. The sprinkler system is installed on the pillar on the right side of the bottom plate. The geotextile consists of a water inlet, a flow switch, a metal hose and a shower head. The shower head is provided with a splash-proof cover. When used, the shower head is placed in a transparent cover and covered with a splash-proof cover. And fasten the clip to prevent water from spilling. The collecting trough is rigidly coupled with the vibrating head, and the collecting tube is arranged on the left side, and the supporting trough is provided on the bottom of the collecting trough. The sample is laid on the grid, pressed with a geotextile holder, and then the flip bolt and the star are used. The handle is pressed tightly. The specific operation method of turning the bolt and the star handle is as follows: due to the anti-seepage requirement between the collecting trough and the geotextile holder, the outer wall is provided with a sealing ring, so that there are two opening cap bolts with a long groove, when When the geotextile holder is difficult to remove, the geotextile cover bolt can be rotated in reverse, and the bayonet will lift the holder for convenient operation. Geotextile effective pore size measuring instrument is suitable for the determination of effective pore size of all types of geotextile products. Its performance is in accordance with GB/T17634-1998 "Determination of effective pore size of geotextiles and related products - wet screening method". The effective aperture analyzer uses a single layer of geotextile without tension and its related product samples as a screen to spray water on the sample and the graded granular material at a specified vibration frequency and amplitude to pass the particle grading material. Sample. The effective pore size of the sample is indicated by the passing particulate material and the specific particle size. Geotextile Effective Aperture Tester Operation Step 1. Take out the holder 6, and flatten the sample without any force on the support grid 18, and then press it with the holder, and the sample should be kept horizontal. 2. Spread the granular material selected according to the standard evenly on the sample. 3. Turn on the power and turn on the power to switch 15. 4. Set the vibration power time on the timer 17 (according to the gb/t17634-1998 standard, it can be set to 600 seconds. The instrument timer has two-speed timing function, which can be set from 0 to 99.99s and 0 to 99 minutes and 59s respectively) . 5. The water inlet 14 is connected to the regulated water source. The shower head 10 is placed in the transparent cover 8, covered with a splash cover, and the clip 7 is fastened, and the flow regulating valve 13 is opened to spray the sample. 6. Press the start button 16 to start the test. 7. The particles passing through the sample flow out of the collecting tank 3 and are collected. 8. After the set time has elapsed, stop the instrument from vibrating. 9. Collect the failed particulate material and sample. 10. The test results are processed according to the gb/t17634-1998 standard. 11. After the instrument is finished, turn off the power and clean the instrument.
