粉砂地质区污水系统建设的抗沉降措施

Anti-settlement Measures in Construction of Sewage Systems in Silt Areas

以绍兴滨海新城污水系统建设为例,介绍了粉砂地质区污水系统建设在设计和施工方面采取的抗沉降措施。针对设计,主要介绍了从前期规划设计和实施阶段施工图设计采取的抗沉降措施;针对施工,主要介绍了从管道连接、回填密实度处理等方面采取的抗沉降措施。最后,通过对实例沉降观测记录分析,验证采取抗沉降措施的效果,也给类似粉砂地质地区工程设计施工提供了一些借鉴。

Taking Shaoxing Binhai new city sewage system construction as an example, anti-settle- ment measures in design and construction of the sewage system in silt area were introduced. For the de- sign, the anti-settlement measures adopted in the early planning design and construction drawing design during the implementation phase were described. For the construction, the anti-settlement measures a- dopted in the pipeline connection, backfill and compactness treatment were expounded. The effects of the anti-settlement measures verified through the observation record analysis of the settlement examples, and a reference for engineering design and construction in similar silt areas was provided.
