摘　　要：以梅龙大道东侧河道为例,为解决河道护坡塌陷问题,通过采用注水式堵水气囊阻断水流,形成一个安全可靠的施工空间,对破损段管段进行钢管内穿结构性修复,解决了高水头、大直径、快流速的污水管道封堵及修复问题,减少了人员下井及水下作业时间,增加了安全系数,整个封堵及修复过程不产生垃圾,对管道排水不产生后续影响,取得了较好的社会效益和经济效益,可为类似工程提供一定的借鉴。Taking the river channel on the east side of Meilong Avenue as an example,in order to solve the problem of slope protection collapse of the river channel,a safe and reliable construction space is formed by water injection type water shutoff air bag to block the water flow.The structural repair of steel pipeline inner penetration is carried out for the damaged pipeline section,which solves the plugging and repair problem of sewage pipeline with high water head,large diameter and fast flow speed,the time for personnel to go down the well and underwater operation is reduced,and the safety factor is increased.It can provide some reference for similar projects.
