:通过对某工程采用的深层搅拌连续桩墙的抗渗试验 ,认为桩机喷头喷浆不均匀、叶片搅拌不均匀、上下进尺不均匀等是导致深层搅拌连续桩墙整体防渗能力降低的主要原因 ,提出“双排套打”或“多排套打”是目前用深层搅拌桩进行闸基防渗加固的较好措施之一 Through the impermeability test of deep mixing continuous pile wall used in a project, it is considered that the uneven spraying uniformity of the pile machine nozzle, the non-uniform mixing of the blades and the unevenness of the upper and lower scales are the main factors leading to the decrease of the overall anti-seepage capacity of the deep mixing continuous pile wall Reason, put forward “double row sets of play” or “multiple rows of sets of” is currently using deep mixing pile impermeable reinforcement gate one of the better measures
