聚酯长丝土工布

聚酯长丝土工布是采用聚酯切片经纺丝成网、针刺固结等工艺制成。具有良好的力学功能,透水性好,并能抗腐蚀,抗老化,具有隔离、反滤、排水、保护、稳固、加筋等功能,能适应凹凸不平的基层,能抵抗施工外力破坏,蠕变小,长期荷载下仍能保持原有的功能。广泛用于水利工程堤坝及护坡的反滤,渠道的隔离、防渗,公路、铁路、机场跑道的基础隔离、反滤、排水、土坡、挡土墙及路面加筋、排水,港口工程的软基处理,海滩围堤、海港码头及防波堤加筋、排水等领域。
Filament fiber polyester geotextile is made of PET chips which are spinned into a net and needle punched. It has good mechanical function, good water permeability, and it can resist corrosion,anti-aging with the function of isolation,filtration,drainage,protection,stabilization,reinforcement and others. it can adapt to uneven base, resist external damage of construction,creepage is small, and can maintain its original function under long-term load. For the water conservancy project, It is widely used in the filtration for the dam and slope, channel’s isolation and anti-leakage. It can be used for isolation, filtration, drainage, soil slopes, retaining walls, pavement reinforcement and drainage for the foundation of roads, railways, airport runways, It can also be used in treatment for the soft foundation of the port, reinforcement and drainage for the beach dikes, port terminals, dam and other fields.
