深水直立式防波堤石料抛填施工工艺及质量控制

针对某深水直立防波堤基床抛填施工作业面小、抛填石料量大、工期紧且抛填质量要求高等特点,通过合理选择抛填施工船机设备,确定粗抛、细抛、补抛等基床抛石施工工艺,科学设计抛填网格并在施工中严格控制,确保了基床抛石施工的进度、质量,从而保证了整个工程按期竣工。

Construction Technology and Quality Control of Placement of Rock Material for Vertical Deepwater Breakwater

In view of the problems of limited working face in placement of materials to form the foundation bed for a deep water vertical breakwater, voluminous placement of materials, tight construction schedule and rigorous quality requirements of placement of the materials, a technological process of rough placement, fine placement and patching was determined together with the reasonable selection of suitable vessels and machinery for placement of fill materials. Pumping grids were scientifically designed and strictly controlled. With these measures, the progress and quality of placement of materials for the foundation bed were ensured, thus completing the whole project in due time.
