In practice, wet and submerged repair and reinforcement is often encountered, such as damage to tunnels due to wear and tear and water erosion, leakage in concrete diversion channels, etc. Due to the presence of large amounts of water in the environment, it is very difficult to achieve dry conditions for repair and reinforcement of such structures, which often requires wet or submerged construction. In addition, dams are subject to cracks and surface peeling in submerged concrete or reinforced concrete due to the complex environment they have been in for a long time, and concrete is also subject to pressure water due to dam storage. Conventional repair materials pursue high groutability, good flowability of the slurry but it is extremely easy to disperse when it encounters water scouring, failing to achieve the effect of grouting, wasting material seriously and washing away lost material will also cause pollution to the environment. As the mountain is relatively fragmented, the grouting process consumes a large amount of grout, so it is necessary to keep the grouting within certain limits. Therefore, the specific grouting construction conditions also place special requirements on the grouting material, towards the need for grouting material to meet the premise of groutability and mechanical properties, but also the need to meet the construction requirements of underwater or moving water conditions, as well as the control requirements of the grout flow range. This paper introduces a controlled grouting material which, by regulating the setting time and viscosity of the material, allows the grouting material to be well adapted to grouting under local subsurface moving water conditions.
