I have been working on a project where i am facing an problem wit is as follows :
Reservoir water has become acidic of ph 3+ due to existence of coal mines on the upstream side of the dam. The concrete of the dam has eroded & further deterioration is continued which make the dam stability in danger . To save the front face of the dam , necessary barrier is required to avoid further deterioration.
What type of protective measures should be taken to solve this problem under water condition ?
The Thickness of steel plates of the panstock has reduced by 3 to 6 mm and there is a possibility of bursting of the pipes under the hydro static water pressure. The panstock pipes are lying under ground at about 30 to 40 degree of the power house and it is not possible to replace the whole length with further steel lining .We are of the view that some kind of polymer coating be done inside the panstock under wet condition so as to achieve the required strength of the pipe to the designed value. It may be suggested what kind of polymer coating maybe done & whether the thickness provided may achieve the required design strength of the pipe by bonding with the steel as one unit.
