软土地基上大直径玻璃钢夹砂管用作压力输水管的研究

摘要

The basic principles, key techniques, and the construction experiences of the application of glass fiber reinforced plastic pipe in soft soil foundation were studied, and the reasons for the accidents were figured out based on investigation and analysis. Through experiments, the suggestions on the section pattern and slope of gutter, the foundation trench backfilling materials and their density control were proposed. This paper also discussed the key techniques of the application of glass fiber reinforced plastic pipe on soft soil foundation, including: the selection of pipe rigidity, density of backfilling materials, gutter structure, and connector types, etc.%探索了玻璃钢夹砂管在软土地层中应用的基本规律、技术关键和施工经验,通过调查分析得出玻璃钢管出现事故的原因.通过试验对沟槽断面形式、坡度大小、基坑回填的材料及其密实度控制等方面提出建议.探讨了软土地基上埋地玻璃钢管设计的关键技术,包括:管道刚度的选择、回填材料密实度、沟槽构造和接头形式等.
