水泥土截渗墙安全度高,抗渗能力强,耐久性好,适应性广。在工程实践中,由于水泥土截渗墙受施工方法及其他因素的影响,施工质量有时达不到设计技术要求,会出现墙体开叉、搅拌深度不够、搅拌不均匀、断浆、少浆、夹泥、孔洞等缺陷,影响防渗效果。因此,进行水泥土截渗墙质量检测,发现和解决质量问题,及时采取处理措施很有必要。本文采用多道瞬态面波法、纵波垂直反射法、高密度地震映像法等多种无损检测技术对水泥土截渗墙进行质量检测研究,探讨了一套快速有效的检测方法。
Cement soil cutoff wall high security, impermeability, durability, wide adaptability. In engineering practice, due to the impact of construction methods and other factors, construction quality may not meet the design and technical requirements sometimes, there will be split wall, stir depth is not enough, uneven mixing, broken pulp, less pulp , Mud clip, holes and other defects affect the anti-seepage effect. Therefore, the quality of cement soil cutoff wall testing, quality problems found and solved, timely measures are necessary. In this paper, multi-channel transient surface wave method, vertical wave vertical reflection method, high-density seismic mapping and other non-destructive testing techniques for cement soil cutoff walls for quality inspection, discussed a set of fast and effective detection methods.
