Geotextile is used to reinforce the soft foundation of fish ponds
The main purpose of using geosynthetics to reinforce the embankment is to improve the overall sliding safety factor of the embankment or to use steep slopes to reduce land occupation under the premise of ensuring safety. Simply using flat geosynthetics to strengthen the soft foundation can increase the bearing capacity, but it has little effect on improving settlement. The settlement is generally relatively large and the settlement duration is relatively long. Therefore, in the case of thick soft soil layers, only laying geosynthetics is not very effective.
Laying geotextile reinforcement is mainly used to strengthen the foundation where the local silt layer is not very thick, and it is generally used in combination with a medium-coarse sand cushion. If the embankment line crosses the fish pond or ancient river channel, the silt embankment foundation will be treated. Due to the small treatment area, it is not economical to adopt other embankment foundation treatment methods. At this time, you can consider strengthening the high quality polyester nonwoven geotextile.
On the one hand, the reinforcement effect of the geotextile on the sand cushion makes the embankment load spread to both sides, reducing the central stress of the subgrade; on the other hand, the lateral displacement and lateral compression are effectively suppressed, thereby reducing the vertical compression deformation That is, the main principle of geotextile to reduce settlement is to reduce the effective load of the embankment center on the one hand, and reduce the lateral displacement and lateral extrusion on the other. In addition, the polyester nonwoven geotextile manufacturers and its underlying sand layer act as horizontal drainage channels to accelerate the drainage and consolidation of soft soil.
Geotextile is used to reinforce the soft foundation of the Luxi River crossing the fish pond section. Although the settlement is large and the settlement lasts for a long time, most of the settlement is completed during construction. In the design process, proper retention of the height of the embankment or increase the height of the embankment after the settlement is basically stable can ensure the design elevation of the top of the embankment. Two to three years after the earth embankment is built, concrete pavement is laid on the top of the embankment. After years of operation, no cracks appeared, proving that the use of polypropylene nonwoven geotextile for sale to reinforce the silt foundation of the Liuxihe fish pond is successful.
