जियोग्रिड कच्चे माल के रूप में उच्च शक्ति वाले पॉलिएस्टर फाइबर या पॉलीप्रोपाइलीन फाइबर का उपयोग करता है, और ताना बुनाई उन्मुख संरचना को अपनाता है। The warp and weft yarns in the fabric are free of bending, and the intersection is bound with high-strength fiber filament to form a firm joint, giving full play to its mechanical properties. Do you know how good its fatigue crack resistance is?
The main effect of asphalt overlay on the old cement concrete pavement is to improve the application function of the pavement, but it does not contribute much to the bearing effect. The rigid concrete pavement under the overlay still plays a vital role in bearing. पुराने डामर कंक्रीट फुटपाथ पर डामर ओवरले अलग है। डामर ओवरले पुराने डामर कंक्रीट फुटपाथ के साथ मिलकर भार सहन करेगा। Therefore, asphalt overlay on asphalt concrete pavement will not only present reflection cracks, but also fatigue cracks due to the long-term effect of load. Let's analyze the stress of the asphalt overlay on the old asphalt concrete pavement: because the asphalt overlay is a flexible pavement with the same nature as the asphalt overlay, the road surface will deflect when subjected to the load effect. The asphalt overlay directly touching the wheel is under pressure, and the surface is subject to tension in the area beyond the wheel load margin. Because the force properties of the two stress areas are different and close to each other, the junction of the two stress areas, that is, the sudden change of force, is easy to be damaged. लंबे समय तक भार के प्रभाव में थकान की समस्या उत्पन्न हो जाती है।



यूनियाक्सियल टेंसिल जियोग्रिड एक प्रकार का उच्च शक्ति वाला जियोटेक्सटाइल है जिसमें मुख्य कच्चे माल के रूप में उच्च आणविक बहुलक होता है, जिसे कुछ एंटी पराबैंगनी और एंटी-एजिंग एजेंटों के साथ जोड़ा जाता है। After unidirectional stretching, the original distributed chain molecules are reoriented to a linear state, and then extruded into a thin plate, impacting the conventional mesh, and then stretched longitudinally. भौतिक विज्ञान।
In this process, the polymer is guided by the linear state, forming a long elliptical network structure with uniform distribution and high node strength. इस संरचना में बहुत अधिक तन्यता ताकत और तन्यता मापांक है। The tensile strength is 100-200Mpa, close to the level of low carbon steel, which is much better than traditional or existing reinforcement materials.
In particular, this product has an ultra-high early international level (elongation of 2% – 5%) tensile strength and tensile modulus. यह मृदा प्रतिबद्धता और प्रसार के लिए एक आदर्श प्रणाली प्रदान करता है। This product has high tensile strength (>150Mpa) and is applicable to various soils. It is a kind of reinforcing material widely used at present. इसकी मुख्य विशेषताएं उच्च तन्यता ताकत, अच्छा रेंगना प्रदर्शन, सुविधाजनक निर्माण और कम कीमत हैं।
