横跨深大基坑的大直径雨水管线悬吊保护设计

Design of Large Diameter Rain Water Pipeline Suspension Protection across Deep and Large Foundation Pit

随着城市的快速发展,明挖法施工在城市中修建地下道路不可避免地与地下管线交叉甚至发生冲突。为了做好基坑施工期间管线的保护工作,文章对广渠路东延工程中横跨基坑的Φ1600雨水管线进行悬吊保护设计。计算表明,设计参数和方案满足雨水管线悬吊保护要求。该方案可供类似工程参考。

Open excavation is crossed and even conflicted with underground pipelines inevitably during the construction of underground roads in the city with the rapid development of the city.Suspension protection design is carried out on the Φ1600 rain water pipeline cross the foundation pit during eastward extension project of Guangqu Road in the paper.The calculation shows that the design parameters and scheme meet the requirements of rain water pipeline suspension protection.The scheme can be used as a reference for similar projects.
