为了解决在通航河道中使用绞吸式挖泥船隔河出土施工,又不影。向正常通航,我们参考大型挖泥船潜管施工经验, 结合60立米绞吸挖泥船的实际情况,研制了浮筒式潜管。浮筒式潜管是在输泥管两侧增设浮筒,把沉浮系统和输泥系统组合在管线上,向浮 In order to solve the use of cutter suction dredger in the navigable channel across the river unearthed construction, not shadow. To the normal navigation, we refer to the experience of the construction of large dredgers submarine pipe, combined with the actual situation of 60 cubic meters of cutter suction dredger, developed a float tube. Floating tube is in the dip tube on both sides of an additional float, the sinking system and the mud system combined in the pipeline, to float
