摘　　要：水中钢板桩围堰施工过程中,相邻钢板桩锁口局部易发生漏水现象,传统处理方法止水效果较差,甚至还会污染水域。传统方法虽然有着一定的止水效果,但工时长、费用高,而且后期锁口复漏率高,针对现有技术存在的不足,我们提出一种水中钢板桩围堰快速止漏方法,并结合施工实例详细阐述了该方法的关键技术。During the construction of steel sheet pile cofferdam in water,in view of the local water leakage at the lock mouth of adjacent steel sheet piles,the traditional treatment method has poor water stop effect,and even pollutes the water area.Although the traditional method has a certain water stop effect,it has the disadvantages of long working hours,high cost and high re-leakage rate of lock mouth in the later stage.In view of the shortcomings of the existing technology,a kind of quick leakage stoppage method for the steel sheet pile cofferdam in water is put forward,and the key technology of this method is elaborated in combination with the construction example.
