防洪堤工程中预制桩的应用及施工

Application of Precast Pile in Flood Protection Dike

根据温州特性土层和重点建设区的工程地质分析,讨论了预制桩在城区防洪堤工程中的应用及施工方法.目前这一方面的理论研究和工程实践都进展的很深入.采用预制桩作为防洪堤工程的桩基基础,除了预制桩本身的优点外,还有耐久性好,能满足防洪堤寿命的要求;预制桩施工均为工厂化生产,工艺成熟,质量有保证;沉桩施工速度比灌注桩施工速度快,对防洪堤的早日建设完成有利,并具有安全、经济、可行的特点.

The application of precast pile in flood control engineering is discussed in the article in the perspectives of theoretical studies and constructing techniques according to the geological analysis and the special soil layer of Wenzhou. It shows that the construction procedures and technical measures of sinking pile are better than that of filling pile. The precast piles, as the pile foundation of flood protection dike, are probed to be safe, economical and practical with good quality and long duration.
