In today's many projects are used in non-woven geotextile, but the application of the material did not cause everyone's attention, many projects because there is no use of such materials, also led to a lot of problems. Non-woven geotextile is mainly used in highway, railway, water conservancy, electric power, soil and water conservation and environmental greening and infrastructure construction, with excellent filtration, isolation, reinforcement and protection, and high tensile strength, good permeability, high temperature, Freezing, anti-aging, corrosion resistance and other advantages.
In many construction, because there is no use of non-woven geotextile, resulting in the collapse of the dam, burst, piping major problems. Do not geotextile, river water after the impact of the stones behind the dam, resulting in mud stone collapse. The use of geotextile, the river does not touch the sediment, the impact is only a hundred years of life of the geotextile, geotextile in the construction of the importance of its resistance from its resistance and resistance to deformation. Of course, geotextiles in the case of beyond the affordability, will be deformed.
Geotextile manufacturers from the overall project for us to analyze the average tension of the plate is limited, but in the dam and the bank soil geotextile anchorage, due to rigid anchorage and the role of huge water pressure "fixture effect" in the dam Under the action of load, if you do not consider the geotextile and the dam body interaction, geotextile will produce their own can not bear the tensile deformation. In addition, the rigidity of the geotextile has a small effect on the structural displacement of the high earth-rock dam. Under the special area of the rigid anchoring end, the elongation of the geotextile should be paid attention to, and the geotextile should be adapted to the local Large deformation of the area. However, due to the deformation of the geotextile by the displacement of the dam on both sides of the restrictions, so the tensile force within the geotextile will be limited, reducing the possibility of cracking the geotextile was broken.
Therefore, in the purchase of non-woven geotextile must be in accordance with the construction requirements, the procurement of the corresponding specifications of the geotextile.
The role of geotextile:
1, the first is to play a very good isolation, making the material is not easy to drain, can be very good to maintain the overall function of the material, making the bearing capacity to strengthen.
2, filtration, mainly water from the fine soil to the coarse material when the geotextile has a good permeability, water flow, the effective reduction of sand and stone inflow, to ensure the stability of water projects.
3, drainage function is good, can be formed in the soil within the drainage channel, the excess liquid and other discharge.
4, reinforced, effectively enhance the stability of building structures, improve the quality of soil.
