浅析吹填施工技术在造地工程中的应用

通过吹填造地的工程实例,介绍了吹填造地的设计、施工工艺及施工方法。吹填料源以海砂为主,辅以淤泥和土料。吹填工艺采用挖运抛吹的方案。吹填造地采用耙吸式挖泥船在海上挖砂装舱,重载航行至吹填区附近的储泥坑抛砂,绞吸式挖泥船将海砂吹填至筑陆区。吹填造地结合城市新区用地需要,具有明显的社会效益和经济效益。

Application of the Hydraulic Reclamation Construction Technology to Reclamation Project

Through a project example, the design, construction techniques and construction methods of land reclamation are described. Main material source for hydraulic fill is sea sand, supplemented by silt and soil material. The program of blowing sand reclamation is digging transport parabolic and blowing. Dredging and stowing the sand by drag-suction dredger, than slinging at the soil storage pit near the reclamation area by heavy load sailing, the craft that sea sand is blown to reclamation area by cutter-suction dredge. Blowing-sand reclamation construction has significant social and economic benefits combined with the need of newly-developed urban area.
