用链斗式挖泥船开挖码头前沿,一般码头前沿水深较难达到设计要求。如用抓扬式挖泥船补挖,则工程衔接较难掌握,生产成本必然提高。工期也将延长,影响码头正常使用。 我处用500米~3/时链斗式挖泥船对码头前沿的开挖进行了一些尝试,质量均达到设 With the bucket-type dredger excavation front of the pier, the pier is generally difficult to meet the design requirements of the water depth. If grasping the digging dredging excavation, the project is difficult to grasp the convergence, production costs will inevitably increase. Duration will also be extended, affecting the normal use of the pier. I use the 500 m ~ 3 / hour chain bucket dredger on the cutting edge of the pier some attempts have been made to set
