Datianxia Water Conservancy Hub
2025-05-09
Project Name: Water Seepage Treatment of the Left and Right Bank Installation Room Structural Joints of the Datengxia Hydropower Hub
Materials Used: LW water-soluble polyurethane grouting material, HW water-soluble polyurethane grouting material
Treatment Results: The main concrete structures of the left and right bank workshops and installation rooms have been completed. During the inspection of the workshops and installation rooms, seepage was found in the upstream structural joints of installation rooms #1 and #2 on the right bank and installation rooms #3 and #4 on the left bank. Long-term observation showed that the seepage amount varied with upstream water storage. Preliminary judgment indicated possible damage to the water stop. After repair, the water stop function did not reach its original state. After grouting the structural joints with LW and HW water-soluble polyurethane grouting materials, the seepage was effectively sealed. Continued observation under varying upstream water pressure showed no re-seepage.
