Geotextiles is a new type of engineering building materials, It has the characteristics of light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance, and excellent performance in engineering construction such as filtration, drainage, insulation, reinforcement, seepage , and protection. , so it is used more and more in civil engineering.
The thickness of the geotextile is a parameter in its product performance, and a special geotextile thickness gauge is required to detect its thickness. Commonly used geotextiles are generally 2mm, 4mm and 7mm thick. The geoYG060 textile thickness gauge is suitable for thickness testing of geotextile less than 10mm thick, with excellent characteristics such as fast testing speed, high accuracy, simple structure, easy maintenance and easy operation.
Geotextile Thickness Gauge When testing the thickness of geotextiles, the relevant geotextile testing standards must be followed. The specific standards are as follows: p
JTG E50-2006 Testing regulations for geosynthetics in road construction
ISO9863 1:2005 Determination of thickness of geosynthetics under specified pressure
IOS 13761.1-2009 Determination of thickness of geosynthetics under specified pressure
The geotextile thickness test steps are as follows:
1. Prepare YG060Geotextile Thickness Gauge1 set, 1 ZB01 disc sampler;
2. Use the ZB01 Disc Sampler to cut 5-10 circular samples at different positions of the test sample, mark them for later use;
3. Select the appropriate print weight according to the testing standard, rotate Sie the handle with your counterclockwise to the right so that the cam takes the full weight of the roller and pressure weight;
4. Choose a suitable presser foot, clean the reference plate and the surface of the presser foot, and then put the presser foot on the reference plate, making sure that the triangular blade of the presser foot with the inverted V-shaped groove is aligned
5. Select the dial gauge and insert it into the hole of the gauge stand 0.1-0.2mm below the top, then tighten the nut and reset the gauge;
6. Raise the presser foot, place the pattern between the reference plate and the presser foot, lower the presser foot and the pattern withstands the specified pressure;
7. After 30 seconds, read the reading on the dial indicator, then you can find the thickness of the geotextile sample under pressure, then the sample replace and repeat the above process to complete testing of all samples.
8. By summarizing the From the results of all the test samples, the thickness of each part of the geotextile and the average thickness of the geotextile can be obtained, which is of positive importance for product quality control.
