应用漂管沉降施工工艺穿越河流

River Crossing Using Floating & Settling Pipeline Method

以浙江省镇海炼化—杭州康桥成品油管道工程为例 ,详细介绍漂管沉降工艺在管道穿越河流中的应用。其中着重介绍了水下管沟开挖及测量、漂管到位及充水下沉、稳管及管沟回填等施工工艺。该方法的优点是施工简单、造价低、工期短、经济效益显著、不破坏农田 。

By taking Zhenhai-Hangzhou oil pipeline project as an example, the writer introduced the river crossing using floating & settling pipeline method, including underwater trenching, floating pipeline position measuring, pipeline settling with filling water, underwater pipeline stabilizing, underwater backfilling & some construction cautions etc. This method is suitable for larger or medium river crossing. It has many advantages e.g. construction simple,cost low,working period short & no-damage to farmland etc.
