远距离输送砂浆充填砂袋施工技术

以肯尼亚拉姆港项目疏浚及吹填工程为例，针对临时围堰及引堤建设中陆地砂源与充砂袋施工区域距离远的问题，对远距离输送砂浆充填砂袋施工技术进行研究。创造性地提出通过优化泵机组合、合理设计远距离砂浆输送管线及适用于该管路系统的合流器及分流器，实现安全、高效的远距离输送砂浆充填砂袋施工。可减少船机设备的投入，降低施工成本，保障施工进度，取得良好的经济和社会效益。目前国内针对远距离输送砂浆充填砂袋施工技术尚无成熟的施工工艺，该技术的成功实施对类似工程有重要的参考意义。

Construction technology of long-distance pipeline mortar transportation for sand bag filling

Taking the dredging and reclamation project in Kenya Ram Harbor as an example,and aiming at the problem that the distance between the onland sand source and sand filling bag construction area is too long,we study the construction technology of pipeline mortar transportation for sand bag filling,and propose creatively a safe and efficient method for the long-distance mortar transportation for the filling sand bag construction by optimizing the pump combination,rationally designing the long-distance mortar conveying pipeline and the combiner and the splitter suitable for the pipeline system,by which,we can reduce the input of equipment,cut down the construction cost,guarantee the construction progress,and achieve good economic and social benefits.At present,there is no mature construction technology of long-distance pipeline mortar transportation for sand bag filling in our country.The successful implementation of this technology has important referential significance for similar projects.
