随着市政建设的不断发展,对雨、污水管道技术性能的要求日趋提高。国内外市政建设技术人员经不断努力创新,推出了新型的施工方便、劳动强度低的玻璃钢夹砂管。该种产品正在不断替代陈旧的钢筋混凝土管。在工程实践中通过对拉森钢板桩入土深度、主动土压力、被动土压力、基坑抗隆起等验算更显现该产品的优越性。 With the continuous development of municipal construction, the requirements for the technical performance of rain and sewage pipelines are increasingly increasing. Domestic and foreign municipal construction technicians have continuously strived to innovate and introduced a new type of FRP sand-filled pipe with convenient construction and low labor intensity. This kind of product is constantly replacing the old reinforced concrete pipes. In the engineering practice, the superiority of the product is further revealed by checking the depth of the Larsen steel sheet pile, active earth pressure, passive earth pressure, and anti-uplift of the foundation pit.
