全封闭式充砂管袋围堰在填海项目水闸施工中的应用

Application on Fully Enclosed Sand-Filled Pipe Bag Cofferdam in Sluice Construction of Reclamation Project

充砂管袋围堰具有结构简单、施工方便和迅速的优点,被广泛应用于水利水电施工导截流、河湖边坡治理等。以福州市江阴东部填海造地项目排涝水闸为例,结合地质条件和潮汐特征,采用全封闭式充砂管袋围堰进行导截流。笔者详细介绍了充砂管袋围堰施工工艺及控制要求。检测结果表明,围堰施工质量满足要求,堰体牢固、稳定、无变形。该类型围堰在项目中的应用,为类似工程提供了借鉴。

Sand-filled pipe bag cofferdam has the advantages of simple structure,convenient and rapid construction,which is widely used in water conservancy and hydropower construction diversion and closure,river and lake slope treatment.Taking the drainage sluice of Jiangyin East Reclamation Project in Fuzhou as an example,combined with the geological conditions and tidal characteristics,the fully enclosed sand-filled pipe bag cofferdam is used for diversion and closure.The construction technology and control requirements of sandfilled pipe bag cofferdam are introduced in detail.The test results show that the construction quality of the cofferdam meets the requirements,and the cofferdam body is firm,stable and non-deformation.The application of this type of cofferdam in the project provides reference for similar projects.
