【摘要】 文章以扬州市长江防洪能力提升堤防加固一期工程的地连墙工程为研究背景，分析总结了双轮搅地连墙机的施工工艺流程及技术要点，并在实际工程中进行了应用，成功实现了堤防成墙厚度50 cm、墙深15 m、单幅宽2.8 m的技术目标。经现场随机抽样检测，地连墙的墙身厚度、长度、完整性、位移及渗透系数等技术指标均满足设计要求。研究表明，双轮搅地连墙机具有施工效率高、成墙质量好、适应性强等优势，特别适用于堤防加固、水利防渗等对墙体连续性和抗渗性要求较高的工程，施工经验和技术参数可为类似工程提供可靠的技术参考和实践依据。更多还原

【Abstract】 Taking the underground diaphragm wall construction of the first-phase of the Project of Embankment Reinforcement for Improving the Flood Control Capacity of the Yangtze River in Yangzhou City as the research background, this paper analyzes and summarizes the construction process and technical key points of the double-wheel stirring machine for construction of underground diaphragm wall. It has been applied in actual engineering construction, successfully achieving the technical goals of the diaphragm wall thickness of 50 cm, wall depth of 15 m, and single span width of 2.8 m for the embankment. Through the on-site random sampling detection, the technical indicators of the diaphragm wall thickness, length, integrity, displacement, and permeability coefficient, all met the design requirements. Research results have shown that the dual-wheel stirring machine for diaphragm wall construction has the advantages of high construction efficiency, good wall-forming quality, and strong adaptability. It is particularly suitable for projects with high requirements for wall continuity and impermeability, such as embankment reinforcement and hydraulic structures seepage prevention. The construction experience and technical parameters can provide reliable technical reference and practical basis for similar projects.更多还原
