预应力混凝土管桩在上海白龙港污水处理厂升级改造工程中的应用

Application of Pre-stressed Concrete Piles in Shanghai Bailonggang Sewage Treatment Plant Upgrading Project

预应力混凝土管桩是被普遍用于高层建筑地基基础的一种桩基施工工艺,用于市政污水处理工程尚不多见。结合工程实际,对解决工程基坑抗浮和沉降的方法作了比选,并简要阐述了预应力混凝土管桩压桩及其质量控制过程。

Pre-stressed concrete piles are commonly used in high-rise building construction as a foundation treatment.Its application in the municipal wastewater treatment works is still rare.Combined with this engineering practice,several anti-buoyancy and anti-setting methods of foundation pit are compared.Brief description of pre-stressed concrete pile's pile pressing and quality control processes is presented.
