摘　　要：本文结合沭阳闸柴米地涵实际工程案例,对运行条件下大型水利工程中承受8m左右水压的伸缩缝堵漏处理方案进行了研究,提出先使用土工布和聚氨酯化学注浆材料构造人工止水带,将伸缩缝内绝大部分漏水堵住,再对仍有渗漏水的部位采用高压注浆机注浆处理的方案,并结合实施效果,总结了该技术的可行性与局限性,以期为后续类似工程施工提供指导借鉴。This paper combines the actual working case of the Shuyang sluice to study the leakage plugging scheme of expansion joints under the operating conditions of large-scale water conservancy projects with a water pressure of about 8 meters.It proposes to first use geotextile and polyurethane chemical grouting materials to construct an artificial waterstop to block most of the leakage in the expansion joint,and then use a high-pressure grouting machine to grout the parts that still have seepage.The feasibility and limitations of this technology are summarized based on the implementation effect,in order to provide guidance for subsequent similar projects.
