填海造陆过程中的“筑岛”运砂施工技术

Construction Technology of Sand Transportation for "Building Island" in the Process of Land Reclamation from Sea

填海造陆工程会遇到由于浅海滩涂因海浪冲刷而造成海砂损失、地基软弱等问题。经过方案比选,最终采用临时"筑岛"的施工方案,通过采取储砂平台软基处理、周边防护、施工运砂便道等措施,顺利地进行了储砂和倒运回填,保证了造陆施工质量,且节约了工期,可为类似工程提供借鉴。

The sea reclamation projects will encounter the problems of sea sand loss, weak foundations and so on due to the surf erosion of shallow beaches. After the scheme comparison and selection, the construction scheme of temporary island-building is finally adopted, and sand storage and backfilling are successfully carried out by means of soft foundation treatment of sand storage platform, perimeter protection and pathway for construction and sand transportation and so on. It not only ensured the quality of land reclamation construction, but also saved the construction period, which can provide references for similar projects.
