Abstract: crossing the river, “the subject is often in hydropower construction. How equipment and materials in the shortest time to cross the river, to open a construction job to play a decisive role in the face of hydropower projects. The three gods of water, land and air is able to show by sea using boats to cross the river; land bridge across the river; by air using the ropes for lifting equipment and materials. Waterways in the three-way construction the lowest cost and shortest construction time. This paper focuses on the simple conjoined construction of the pontoon across the river process and precautions Investigative studies have been designed to guide the correct construction methods, so as to achieve the desired results
Key words: conjoined pontoon; crossing the river; technology

1、前言
“过江”这一课题在水电施工中经常出现。怎样在最短时间内将设备物资过江,全面打开施工作业面对水电项目起着决定性的作用。“水、陆、空”三路神仙也是各显其能,水路使用船只过江;陆路架设桥梁过江;空路使用缆索吊运设备材料。三路中水路的施工成本最低,施工时间最短。所以本文就水路中的简易联体浮箱过江技术的相关问题结合工程实例作以介绍。
2、工程概况
