摘　　要：本文以宁波杭州湾新区慈溪十二塘围涂工程一期Ⅰ标段为例,介绍了粉砂土地基水闸基础的浅埋式地下连续墙无泥浆固壁施工技术。该施工技术将地下连续墙分为上层连续墙和下层连续墙,先进行分层分段施工,再进行墙体内外侧黏土回填夯实。该施工技术不但降低了施工成本、节约了工期,而且避免了施工中泥浆处理问题,取得了较好的施工效果。In the paper, Ningbo Hangzhouwan New Zone Cixi Shiertang Reclamation project Stage I No. 1 Bidding Section is adopted as an example for introducing shallow-embedded underground diaphragm wall non-slurry wall-reinforcement construction technology in silty sand sluice foundation. The underground diaphragm wall is divided into an upper diaphragm wall and a lower diaphragm wall according to the construction technology. The diaphragm wall is constructed firstly in layers and sections, and then clay is used for backfilling and tamping inside and outside the wall The construction technology not only reduces the construction cost and shortens the construction duration, but also avoids slurry treatment problem in construction with excellent construction effect.
