1.前言将玻璃钢轻质高强的特性应用到玻璃钢管上,开发了以树脂砂浆为中间层的夹层结构玻璃钢(FRPM)管,这种管子大量用于地层松软地区或需要耐腐蚀的场合,因其重量轻,容易安装,所以,可以缩短施工周期。今后,管道的发展趋势是向大规模化、大孔径化发展,而且以围绕环境保护等问题提出的排除交通障碍、减轻噪音和振动、以及减低人工费等管道埋设工程提出的要求变
1. Introduction The application of lightweight, high-strength glass fibre reinforced plastics to glass fibre reinforced plastic has led to the development of FRP tubes with resin mortar as the intermediate layer. These tubes are used extensively in areas where the formation is weak or where corrosion resistance is required. It is lightweight and easy to install, so it can shorten the construction period. In the future, the development trend of the pipeline will be large-scale and large-aperture development, and the requirements put forward by the pipeline embedding project that eliminates traffic obstacles, reduces noise and vibration, and reduces labor costs, such as those proposed for environmental protection, will change.
