摘　　要：水闸防渗安全问题关乎水闸的使用寿命和效率。结合东河水利枢纽水闸防渗加固工程实例,在结合水闸工程和地基评价基础上,使用多波束测深仪检测,发现河道深层淤泥存在“沙冒石跑”、防渗墙渗漏失效的现状。提出了防水墙顶端将与水闸底座板直接衔接的钢板桩防渗墙加固结合闸基混凝土桩进行基础加固的措施。在护坦外,使用膜袋混凝土护坦方案,提升原有的空箱防护体稳固性的综合加固治理措施。The safety issue of anti-seepage in water gates is related to their service life and efficiency.Taking the example of the anti-seepage reinforcement project of the Donghe Water Conservancy Hub sluice,and based on the evaluation of the sluice project and foundation,using a multi beam depth sounder for detection,it was found that there is a current situation of"sand and stone running"and anti-seepage wall leakage failure in the deep silt of the river channel.A measure was proposed to reinforce the steel sheet pile anti-seepage wall directly connected to the water gate base plate at the top of the waterproof wall,combined with the concrete pile of the gate foundation for foundation reinforcement.A comprehensive reinforcement and treatment measure is taken to enhance the stability of the existing empty box protective body by using a membrane bag concrete protective layer scheme outside the protective layer.
