As a new type of waterproof curtain, several station construction of Qingdao Metro Line 1 successfully used the trench cutting remixing deep wall (TRD). It is difficult to find the factors that affect the wall quality because the method is in situ underground excavating and mixing. This paper has obtained the main factors affecting the TRD quality in Qingdao by studying construction experience and carrying out tests. Geological conditions are fundamental factors. Among them, the parameters of medium-coarse sand layer, the groundwater table, and the humus content are the main factors. The design parameters are the key to high-quality TRD. In the design parameters, the depth inserting into the bedrock, the cement soil ratio, and the mixing time are important factors. And this paper proposes the methods of improving the wall quality, which can provide a theoretical guarantee for the follow-up application of the TRD in the Qingdao area.

青岛地区沟槽Cutting缝搅拌深墙质量的影响因素研究

作为一种新型的防水幕布，青岛地铁1号线的多个车站建设成功地使用了沟槽切割混合深墙（TRD）。由于该方法是在现场进行地下开挖和搅拌，因此很难找到影响墙体质量的因素。通过研究施工经验并进行试验，得出了影响青岛市TRD质量的主要因素。地质条件是根本因素。其中，中粗砂层参数，地下水位和腐殖质含量是主要因素。设计参数是高质量TRD的关键。在设计参数中，插入基岩的深度，水泥土比和搅拌时间是重要的因素。并提出了改善墙体质量的方法，
