Abstract
The water stop system is a key component of the anti-seepage system in concrete face rockfill dams.In order to adapt to the settlement and deformation of the dam body,various structural joints need to be set up for the panel dam.However,in high-altitude areas where the water level changes,the surface layer waterproofing and fixing components are easily damaged by frost heave and lose their fixing function.The rock fill dam project of a certain pumped storage power station adopts a submerged water stop structure on the surface of the panel dam,and the surface plastic filling is directly constructed using a molding machine.At the same time,polyurea is applied to all structural joints and water level fluctuation areas to ensure that the surface water stop is not damaged by freezing ice.After the power station was filled with water,two complete freeze-thaw monitoring tests showed that this technology has certain advantages in the engineering application of panel dams in high-altitude areas.关键词
