Geogrid price? Solution!
- 3 for the road surface, so that the grid and pavement materials are mixed together, can effectively disperse the load transfer, to prevent road cracks;4 can withstand a certain impact load;5 can withstand large alternating load;6 shorten the construction cycle;7 in harsh environmental conditions, can also be constructed;8 can prevent frost caused by surface subsidence and crack;9 can reduce the amount of pavement material;s
How to determine the number of geogrid detection method
- What are the geogrid testing items1) place: in the surface layer of 50cm thick sand gravel or sand (egg) gravel cushion, and compaction, which is not only conducive to improve the friction between the soil and the grid, but also conducive to the consolidation of the foundation drainage.s
What is the grille on the railway?
- High tensile strength and low elongation glass fiber geogrid is a glass fiber as raw material, has a high resistance to deformation, the elongation rate is less than 3%.s
What is the meaning of 80 in geogrid TGSG80
- A model can be viewed as a double grids
Should the municipal geogrid be included in the area of overlap, and, if necessary, the proportion of the area to be included?
- The measurement of municipal geogrid shall not be included in the overlap areas
Geogrid and geotextile which effect is good
- Geotextile has excellent filtration, isolation, reinforcement and protection effect, high tensile strength, good permeability, high temperature resistance, anti freezing, anti-aging, corrosion resistances
Municipal road engineering in the glass fiber grille what role?
- (1) due to the existence of joints and cracks, the old cement concrete pavement as the base of the overall strength is reduced, and under the action of external forces, the asphalt overlay in the three-dimensional stress state. The vehicle passing adiscontinuous board, because the joints and cracks on both sides of the adjacent plate reflecting cracks of vertical displacement difference, asphalt overlay in the corresponding position of the larger shear stress, the shear stress is the main reason of asphalt pavement reflection cracks produced. Usually referred to as the load type reflective crack.(2) due to the exposure of the pavement in the atmosphere, the asphalt overlay and the old cement concrete face have the shrinkage and the temperature stress. Because of the Old Cement Concrete Pavement Stress in the joints is not continuous, so the asphalt overlay and bear it and the old pavement caused by temperature stress, especially under low temperature in winter, the asphalt overlay at the seams, cracks, because of excessive tensile stress and cracking formation temperature reflection crack.s
What is the 110 type bidirectional geogrid?
- As the polymer in the manufacture of plastic polymer in the process of heating with the extension of the process of re orientation, strengthen the link between the molecular chain force, to achieve the purpose of improving its strength. Its elongation rate is only 10% ~ ~ of the original plate of 15%. If the carbon black and other anti-aging materials are added in the geogrid, the utility model has the advantages of good acid resistance, alkali resistance, corrosion resistance, aging resistance and the likes
