Method for stabilizing and lifting channel boards by underwater grouting
A method for stabilizing and lifting a channel board by underwater grouting includes (A) when the channel board is damaged, removing the damaged channel board, cleaning and leveling a gravel layer under the damaged channel board, placing an undamaged channel board installed with first grouting pipes and a second grouting pipe on the gravel layer, wherein multiple geotextile bags are respectively bound to the first grouting pipes; when the channel board is subsided, installing first grouting pipes and a second grouting pipe into first grouting holes and a second grouting hole, respectively; (B) performing a first polymer grouting through the first grouting pipes, and performing a second polymer grouting through the second grouting pipe; (C) cutting off a part of the first grouting pipes the second grouting pipe which are exposed to the channel board, and leveling incisions; and (D) removing excess polymer left on the channel board.
