通州湾腰沙围垦二期通道工程深槽段封堵工艺

围堤封堵和龙口封堵存有一定的相似性，在以往的围填工程技术研究中，往往忽略了两者的诸多不同点，对深槽封堵的研究很少。结合通州湾腰沙围垦二期通道工程深槽段的封堵施工，分析了海岸滩涂区域深槽的形成原因、施工过程中的处理技巧及注意事项。

Deep trough blocking construction techniques of Tongzhou Bay reclamation sand waist phase II channel engineering

There is certain similarity between the dike closure and gap closure.In the research of reclamation technology of the past,many differences were ignored.There is few research on deep groove block.Combined with deep trough blocking construction of Tongzhou Bay reclamation sand waist phase II channel engineering,the cause of deep trough formation of the coastal region is analyzed,while the construction processing techniques and notes are indicated.
