摘　　要：非开挖铺设和无砂铺设有许多益处,用这些技术可以比传统的铺设方法节约费用达60%,并且有利于环境保护。可以预期,这种技术的应用会越来越普遍。新的铺设技术,对于塑料管材及其材料提出了新的要求,而由此新开发的塑料管道系统大部分是基于复合管的。No-digging installation and Sandbed-free installation have many advantages. Using these techniques can reduce costs of the installations by up 60% compared to traditional methods and environmentally friendly. Their use is expected to become increasingly popular in the come years. New techniques introduce new requirements on plastics pipes and raw materials. Most newly developed plastics piping system are based to multilayer pipe designs.
